You Must Know 9 PCBA Equipment

In PCB assembly, there are four main steps of SMT, also known as Surface Mount Technology assembly, using the reflow method. These include the application of paste, automation placement of components as well as soldering as well as checking (plus testing, if required). The most basic equipment needed to perform PCB assembly is:

● Solder Paste Printing machine.
● Solder Paste Inspection (SPI) machine.
● Glue Dispensing Machine.
● Pick-and-Place machine.
● Reflow Soldering Machine.
● Wave Soldering Machine (for the by-hole component).
● Automated Optical Inspection (AOI) machine.
● In-Circuit Test (ICT) Fixture.
● Functional Validation Test (FVT) Fixture.

Stage 1: Paste Application

Solder Paste Printing Machine

The main function of the machine is to print the solder paste onto the PCB. It is able to be used for reflow soldering or wave soldering. The principal components of this machine comprise an extruder and a solder paste pump and a dispensing head.

The solder paste that is extruded by the extruder is then pumped through the pump before being dispensed onto the printed circuit board using the head that dispenses it.

The solder paste needs to be delivered with accuracy so that there are no dry spots or excessive solder remains on the board. This machine is also employed to print other materials like epoxy resin and electrically conductive ink.

Solder Paste Inspection (SPI) Machine

The SPI machine can be used to examine solder paste for any defects like missing or excessive tin, irregularity in the paste solder, and the color of the paste varies between different places in the PCB.

The machine also can determine the existence of particles within the paste, as well as particles that could be present on the pad of the die. In addition to optical microscopes, the SPI machine can also be used with scanning electron microscopes.

Stage 2: Automated Component Placement

Glue Dispensing Machine

Prior to the placement of components prior to component placement, the dispensing device places dots of glue on the PCB, where parts’ body components will rest, keeping the components in position until contact leads are made. This is crucial when using wave soldering, where the power of the soldering wave can dislodge bigger components, as well as for double-sided wave or reflow soldering, to prevent components from falling off.

Pick-and-Place Machine

Pick-and-place machines are probably the most mesmerizing machines in an assembly line. As its name implies, the machine is able to pick up parts and then place them on a blank board. Traditionally, this step of the PCB assembly procedure was done manually, and humans would meticulously select and place the components using an instrument like a tweezer. However, PCB manufacturers nowadays have this procedure automated by utilizing a pick-and-place machine because machines are more precise than humans and operate all hours of the day.

Pick-and-place equipment suctions up SMT components and then places them precisely in their set positions over the paste of solder. They’re thrown down at lightning speed that can reach speeds of up to 30,000 components per hour. When the machine puts components in an orderly, however, almost chaotic way watching the pick and place machines at work is definitely the most entertaining to observe!

Stage 3: Soldering

Reflow Soldering Machine

Rework soldering machines are part of the assembly process and play a crucial function in the final quality of the product.

Many who are just getting started as technicians are usually overlooked. However, it must be acknowledged that without this device, the entire process of production would stop dead in its track.

The goal of the soldering machine for rework is to create electrical connections between different components as well as other parts that are soldered together or coated with solder paste. They can also be employed for rework processes. Hence, they are called Rework stations.

Although there are a variety of kinds of these machines at present, they all operate by heating the parts by applying pressure to them at extremely high temperatures.

Technicians must be aware that when working at Rework stations, specific safety precautions and steps must be taken.

Wave Soldering Machine (For Through-hole Components)

Wave soldering machines are the most common way to solder through-hole components to PCBs. It’s among the easiest cheap, most affordable, and most flexible methods. It can be used to produce a large capacity and can be used with various technology and materials.

In wave soldering machines, molten solder flows continuously over the components when they are passed through a temperature-controlled oven.

A wave soldering machine is designed for high-throughput environments in mass manufacturing. They should be strong sufficient to handle boards that have multiple components that need to be soldered simultaneously.

It means that the majority of wave soldering equipment is designed for boards that are between 1in2 and 2in2 and have a maximum height of 0.0185in or 4 mm above the board’s surface after it goes into the oven.

By adjusting its temperature profile, a wave soldering machine can be used to solder through-hole or surface mount devices. The massive machines have two temperature zones, one to solder to the leads of the through-hole component as well as another one for the soldering of the body of the device.

Wave soldering also offers distinct advantages:

The circuit board is equipped with an extremely short contact, with high-temperature soldering, which may lower the rate of warpage of the board.

The high efficiency of the solder on the wave soldering equipment is beneficial to increasing the performance of joints soldered by it.

Stage 4: Inspection

Automated Optical Inspection (AOI)

Once the boards are complete, they can be put to the test and inspected. Due to the increasing complexity of PCB boards, automated optical inspection is more crucial than ever before. Although it is still possible to focus and identify errors using your eyes, Manual inspection is not efficient for mass production because the workers become tired, and errors can be easily missed. Testing PCBAs is a vital stage in PCBA production to prevent costly re-manufacturing costs and the waste of materials. AOI systems are used to spot problems before they occur during the production process and permit processes to be improved or specific boards to be repaired.

Utilizing optical techniques to identify imperfections, AOI systems can perform checks that are previously carried out manually, however, with higher speed and precision. The AOI camera uses high-definition technology to take pictures of the surfaces of the board and create an image to analyze.

This image is examined against images of an appropriate reference board to find a variety of imperfections, from defective or missing components to scratches and shorts.

In-circuit Test (ICT) Fixture

ICT fixtures can be used for testing PCBs once they’ve been made. The fixture is connected to the PCB via an electrical power supply like that used in the majority of electronic consumer products, like your laptop computer or phone charger, for instance. It has an indicator light to show when the board is powered up.

When the board is powered on, the light will blink. You can then check whether all your components are operating properly and also if any of the traces on the board are shorting out.

It is essential to use an ICT fixture for testing boards using components mounted on surfaces as it decreases the number of external connections needed.

Functional Validation Test (FVT )

Functional Validation Testing (FVT) is the last step to provide the decision to go or not on PCBs that have been completed prior to when they are sent out for shipping. At this point, we’re no longer simply testing for physical imperfections such as tombstones or solder bridges. Instead, the software has been loaded, and we’re testing whether the board functions in the way it is supposed to when utilized in any application that our customers may have in mind for the boards.

FVT simulates the operational environment in which the PCB is used, typically through interfacing the PCB using its connector or by using it as a test point. Functional tests vary from product to product because each PCB tested is distinct. The most popular method of testing functional includes “hot mock-ups,” which is a set-up that is designed to mimic the final product the PCB is used in. However, regardless of how the FVT is configured, they are all based on the same elements of a system: the hardware and software.
