Various factors such as component quality, equipment functionality, soldering procedures, and environmental conditions can contribute to the occurrence of defects. These defects encompass issues like open circuits, cold soldering, short circuits, bridging, incomplete soldering, and misalignment. Additionally, problems may arise with the BGA solder balls themselves, such as missing balls and inconsistent sizes.
Inspecting BGAs poses challenges in ensuring the high quality of the final product. This is primarily due to the positioning of the solder balls beneath the visual inspection and the chip, which makes it difficult to identify cavities within the solder joints. Consequently, the inspection process necessitates the utilization of professional and sophisticated equipment to yield accurate results. Advanced methods employed for this purpose include boundary scans, X-ray inspections, and electrical tests.
Traditional electrical testing methods are well-suited for detecting short and open circuits. On the other hand, boundary scan techniques facilitate access to solder joints through boundary connectors, enabling inspection of short and open circuits across interconnected surface-mounted components. Boundary scan methods offer greater efficacy in testing hidden and obscured joints compared to electrical tests. Both methods effectively assess the electrical performance and conductivity of a circuit board. However, they do not assess the quality of solder. Therefore, it is essential to combine these technologies with other methods to evaluate solder quality and identify solder in concealed and invisible joints.
X-ray inspection, performed using X-ray machines, is capable of detecting additional defects that may arise during BGA assembly. This method enables the identification of soldering issues such as solder balls and paste bridging. Some X-ray machines are equipped with software support that can accurately measure the size of solder balls, provided they adhere to established standards. By generating 3D images, a 2D X-ray machine aids in analyzing inner layers, cold soldered joints, blind vias, and vias on soldered joints of BGAs.

PCB technology will continue to evolve with advances in materials, manufacturing techniques, and design software. As a result, we can expect to see even more innovative and sophisticated PCBs that offer improved performance, reliability, and flexibility.
Printed circuit boards (PCBs) play a critical role in electronic devices, and it is essential that they have a long shelf life to maximize their durability. One of the most effective ways to achieve this is by applying a protective surface finish to shield the copper layer from environmental factors that can compromise its performance. ENEPIG is a technology utilized in the PCB fabrication process to create a protective finish that prevents copper oxidation and other forms of corrosion, thereby extending the lifespan of the PCB.
Therefore, ENEPIG PCB is a type of surface finish used in the manufacturing of printed circuit boards (PCBs). It stands for Electroless Nickel Electroless Palladium Immersion Gold and is known for its excellent corrosion resistance, solderability, and wire bonding capabilities. ENEPIG has become increasingly popular in recent years due to its ability to meet the stringent requirements of modern electronic devices.
In this article, we will explore the composition, manufacturing process, applications, and advantages and disadvantages of ENEPIG PCB, as well as compare it with other surface finishes commonly used in the industry.
Understanding ENEPIG
ENEPIG, or Electroless Nickel Electroless Palladium Immersion Gold, is a surface finish used in the manufacturing of printed circuit boards (PCBs). It is composed of three layers: an electroless nickel layer, an electroless palladium layer, and an immersion gold layer.
The electroless nickel layer is the first layer applied to the PCB substrate. It is applied through a chemical process that involves the deposition of nickel onto the copper surface of the PCB. This layer serves as a barrier between the copper and the outer layers of the surface finish.
The electroless palladium layer is applied on top of the electroless nickel layer. It is also deposited through a chemical process and serves as a diffusion barrier between the nickel layer and the immersion gold layer. Palladium is preferred to other metals, such as nickel or copper, as it is less prone to tarnish and provides better adhesion for the immersion gold layer.
The immersion gold layer is the outermost layer of the ENEPIG surface finish. It is deposited through an electroless immersion process and provides excellent solderability, wire bonding, and corrosion resistance. The thickness of the immersion gold layer can vary depending on the application, but it typically ranges from 0.05 to 0.2 microns.
ENEPIG is known for its excellent corrosion resistance, solderability, and wire bonding capabilities. It is also widely used in the industry due to its ability to meet the stringent requirements of modern electronic devices. However, ENEPIG is relatively expensive compared to other surface finishes and requires more processing steps, which can increase the overall cost of manufacturing PCBs.
How Does ENEPIG work?
To understand the working of ENEPIG, it is crucial to examine the four layers of metal structure that constitute the finish. The process involves the following steps:
Copper Activation
The first step of the process is selectively activating the copper layer to determine the deposition pattern of the nickel layer during electroless plating. A displacement reaction creates a catalytic copper surface on which the nickel will sit.
Electroless Nickel
Copper can react with gold, making nickel a necessary barrier layer to separate the two metals. An oxidation-reduction reaction is used to deposit the nickel onto the catalytic copper surface, creating a layer that is typically 3 to 5 microns thick.
Electroless Palladium
The palladium layer serves as another barrier layer, preventing the nickel from corroding and diffusing into the gold. It also acts as an anti-corrosion and anti-oxidation layer. Similar to the electroless nickel application, this step utilizes an electroless oxidation-reduction chemical reaction to make the nickel react with palladium. The thickness of the palladium layer can range from 0.05 to 0.1 microns, depending on the application.
Immersion Gold
The final step involves the addition of the gold layer to protect against oxidation and friction while providing low contact resistance. Gold also helps to preserve the solderability of palladium. Immersion of gold involves fully immersing the PCB while using a displacement reaction to dissolve palladium and release electrons that reduce the surrounding gold atoms. The gold ions then attach to the PCB surface, replacing some of the palladium. As a result, the finish has a gold plating layer that is typically 0.05 to 0.2 microns thick, significantly thinner than other gold plating techniques.
All in All, the ENEPIG process involves four layers of metal structure that serve as barriers and anti-corrosion/oxidation layers, ultimately resulting in a thin gold plating layer that provides excellent protection and solderability.
ENEPIG PCB Manufacturing Process
The ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold) PCB manufacturing process involves several steps to create a surface finish that provides excellent protection and solderability. The following is a brief overview of the ENEPIG PCB manufacturing process:
Preparation of PCB substrate
The first step is to prepare the PCB substrate, which involves cleaning and degreasing the surface to remove any impurities. The substrate is then etched to remove any unwanted copper, leaving behind the desired circuit pattern.
Electroless Nickel Deposition
The next step is to deposit a layer of electroless nickel onto the substrate. This process involves immersing the PCB in a solution containing nickel ions and a reducing agent. The nickel ions are reduced and deposited onto the catalytic copper surface, creating a layer that is typically 3 to 5 microns thick.
Electroless Palladium Deposition
After the electroless nickel layer is deposited, the PCB is immersed in a palladium solution to deposit a layer of electroless palladium. This layer serves as a barrier to prevent nickel from diffusing into the gold and also provides anti-corrosion and anti-oxidation properties. The thickness of the palladium layer can range from 0.05 to 0.1 microns, depending on the application.
Immersion Gold Deposition
The final step is to immerse the PCB in a gold solution to deposit a layer of immersion gold. This layer provides excellent protection against oxidation, friction, and low contact resistance while also preserving the solderability of the palladium layer. The immersion gold layer is typically 0.03 to 0.05 microns thick.
Quality Control
Throughout the ENEPIG PCB manufacturing process, quality control measures are taken to ensure that the final product meets the desired specifications. This includes monitoring the thickness and composition of each layer, as well as performing various tests to ensure the finish’s reliability and functionality.

Comparison of Final Finish Performance
Upon evaluating the ultimate finishing outcomes across various assembly techniques, it is discernible that Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG) is a fitting choice for an extensive spectrum of assembly prerequisites.
Things To Be Wary About With ENEPIG
Despite its many advantages, the ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold) process has some drawbacks that experts have extensively studied. These include cost, reliability, and fractures.
The cost of the ENEPIG process can be relatively high, particularly due to the high cost of gold. Although palladium prices have decreased in recent years, gold prices have remained high, making the process somewhat expensive. Additionally, the process can be wasteful if gold wire bonding or lead-free coating is not required.
Reliability is also a concern with ENEPIG, particularly with lead and tin bonding. Due to the distribution of palladium and the presence of copper, bonding with these metals may have some reliability issues. In comparison, ENIG (Electroless Nickel Immersion Gold) provides better bonding performance and reliability with these metals.
Finally, the ENEPIG process can result in a brittle surface above the nickel plating, making it more prone to fracturing. This is because the tin-palladium metallic layers form a brittle layer above the nickel plating.
In conclusion, while the ENEPIG process has many advantages, it is essential to be aware of its potential drawbacks. By understanding the limitations of the process, manufacturers can make informed decisions about whether ENEPIG is the most suitable surface finish for their specific application.
Measures to Cost-Effective Surface Finish
Upon considering the advantages and disadvantages of Electroless Nickel Immersion Gold (ENIG) and Electroless Nickel, Electroless Palladium, Immersion Gold (ENEPIG) plating methods, the latter appears to be a more promising option. However, the higher cost of ENEPIG relative to ENIG presents a notable drawback.
One of the primary issues with ENIG plating is the formation of black pads. This problem can be addressed through the implementation of an appropriate plating method. However, with an electroless gold layer in ENIG plating, detecting the presence of black pads can be difficult.
This is due to the fact that the nickel layer remains concealed until the gold layer is chemically stripped away. Additionally, a phosphorus-rich nickel layer is produced naturally upon contact with nickel and gold, as well as solder and nickel before and after soldering, respectively.
The actual causes of black pads can be attributed to poor implementation of technology, resulting in non-uniform crystal particle formation and numerous cracks. Additionally, prolonged immersion of gold can lead to corrosion and crack formation on the nickel surface.
The solder mask utilized can also impact the electroless nickel plating process. An incorrect solder mask can result in a degraded pad surface. Moreover, inadequate cross bonding and rigidity can impede the copper activation reaction. When exposed to a hot electroless nickel solution, the solder mask monomer generates hydrogen, hindering the nickel reaction and disrupting the chemical balance.
Furthermore, the solder mask present in micro vias can undergo electrochemical reactions, impeding the creation of a catalytic copper surface during the plating process.
How To Solve the Black Pad Issue
To effectively the issue of black pads, manufacturers must implement several key measures.
First, analyzing the stabilizer content of the electroless nickel solution and controlling its PH value can help prevent the formation of black pads. Additionally, it is important to prevent nickel surface corrosion when immersing it in gold.
Fortunately, new immersion gold technology has emerged as a viable solution to this problem, as it effectively reduces plating costs while minimizing corrosion on the nickel surface. This is achieved by creating a more neutral pH range of 7.0 to 7.2, which helps to minimize corrosion. Furthermore, the new technology utilizes a lower gold content, thereby reducing the cost of raw materials and minimizing its influence on the nickel surface.
Another key benefit of this new technology is that it produces a nickel film with a columnar structure, which means that micro-cracks can only form on the surface. This further helps to minimize the risk of black pad formation and ensures that the plating process is more reliable and effective.
Conclusion
The ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold) process is a surface finish used in printed circuit board (PCB) manufacturing. It involves the deposition of four layers of metals, starting with copper activation, electroless nickel deposition, electroless palladium deposition, and immersion gold deposition. Each layer serves a specific purpose, such as preventing corrosion, diffusing metals, and providing low contact resistance.
The advantages of ENEPIG include its ability to withstand thermal shock, excellent solderability, and low contact resistance. It is also suitable for high-frequency applications and can handle multiple reflow cycles without degrading. As a result, ENEPIG is commonly used in consumer electronics, automotive, aerospace, and medical devices.
Compared to other surface finishes such as HASL, ENIG, and OSP, ENEPIG offers superior performance and reliability. It is a versatile and cost-effective solution that provides excellent results for a wide range of applications.

What is A Hard Gold Plating PCB?
A hard gold plating PCB refers to a printed circuit board that has undergone a process called hard gold plating on its surface. Hard gold plating is a type of electroplating process where a layer of gold is deposited onto the surface of the PCB to enhance its performance, durability, and conductivity.
In hard gold plating, a layer of hard gold alloy (usually a combination of gold and other metals like cobalt or nickel) is selectively deposited onto specific areas of the PCB, typically the contact pads and connectors. This hard gold layer acts as a protective coating, ensuring reliable electrical connections, resistance to wear, and corrosion resistance.
The main purpose of hard gold plating on a PCB is to improve the conductivity and durability of the contact areas. It helps maintain low electrical resistance, allowing for efficient signal transmission and reducing the risk of defects such as oxidation or tarnishing. The hard gold plating also provides a robust surface for soldering and wire bonding processes, ensuring secure and reliable connections between components.
How Many Types of Hard Gold Plating PCB?
There are typically two types of hard gold plating used on printed circuit boards (PCBs):
Electrolytic Hard Gold Plating: This method involves electroplating a layer of hard gold onto the PCB’s surface. It provides a thick and durable coating, usually ranging from 30-50 micro-inches (0.75-1.25 micrometers) in thickness. Electrolytic hard gold is commonly used for applications where repeated physical contact or environmental factors may cause wear or corrosion.
Electroless Hard Gold Plating: In this process, a layer of hard gold is deposited onto the PCB using a chemical reaction, without the need for an electric current. Electroless hard gold plating typically results in a thinner coating, typically ranging from 3-8 micro-inches (0.075-0.2 micrometers) in thickness. It offers good solderability and is often used in applications where cost and space constraints are important.
What Is The Recommended Thickness Of PCB Hard Gold Plating ?
The recommended thickness of PCB hard gold plating can depend on various factors, including the application requirements and specific industry standards. However, the typical range for hard gold plating thickness is as follows:
Electrolytic Hard Gold Plating: The thickness for electrolytic hard gold plating typically falls between 30 to 50 micro-inches (0.75 to 1.25 micrometers). This thickness range provides a durable and reliable gold coating suitable for applications that involve repeated physical contact or exposure to harsh environments.
Electroless Hard Gold Plating: For electroless hard gold plating, the recommended thickness is generally thinner, ranging from 3 to 8 micro-inches (0.075 to 0.2 micrometers). This thinner gold layer still offers good solderability and corrosion resistance while being more cost-effective compared to thicker gold coatings.
It’s crucial to consider the specific requirements of your PCB design and the intended application when determining the appropriate thickness for hard gold plating.

How Do You Perform PCB Hard Gold Plating?
The process of PCB hard gold plating typically involves the following steps:
Surface Preparation: The PCB undergoes thorough cleaning to remove any dirt, oils, or contaminants from the surface. This is typically done through a combination of mechanical scrubbing, chemical cleaning, and rinsing processes.
Electroless Nickel Plating: Before applying the gold layer, an electroless nickel (EN) plating is usually applied to the PCB surface. This involves immersing the PCB in a bath containing a solution of nickel salts and reducing agents. The EN plating creates a thin layer of nickel on the surface, providing good adhesion and a barrier between the base material and the gold.
Activation: After the EN plating, the PCB is selectively activated using an acidic solution or proprietary activation chemical. This prepares the surface for effective gold adhesion and improves the overall bonding strength.
Gold Plating: Once activated, the PCB is immersed in the gold plating solution. The gold plating process can be carried out using either electrolytic or electroless methods, depending on the specific requirements and desired results.
● Electrolytic Hard Gold Plating: In this method, the PCB is placed as the cathode in an electrolytic cell containing a gold salt solution. An appropriate voltage and current are applied, allowing the gold ions to be reduced and deposited onto the PCB surface.
● Electroless Hard Gold Plating: In this method, the PCB is immersed in an electroless gold bath containing a reducing agent. The gold deposition occurs through an autocatalytic process without the need for an external power supply.
Post-treatment and Quality Control: After the gold plating process, the PCB is thoroughly rinsed to remove any residual chemicals and dried. Post-treatment steps may include applying a protective coating or additional surface finishes to ensure the longevity and reliability of the hard gold plating.
Throughout the entire process, various quality control measures are implemented to check the thickness, adhesion, and overall quality of the hard gold plating. These can include visual inspection, X-ray fluorescence (XRF) testing, cross-section analysis, and adhesion tests.
It’s important to note that the specific details and parameters of the PCB hard gold plating process can vary based on the manufacturer’s capabilities, customer requirements, and industry standards.
