●Limiting reflow cycles, which introduce thermal stresses.
●Storing prepreg materials in a dry, controlled environment to prevent moisture absorption.
Reducing Plating Voids in High-Aspect-Ratio Vias

As vias become narrower and deeper, plating uniformity becomes more challenging. Poor copper deposition can lead to voids, increasing electrical resistance and reducing via reliability.

Best practices for via plating:

●Maintaining bath agitation during electroless copper deposition for even coating.
●Using pulsed reverse plating to promote uniform copper growth inside microvias.
●Controlling sulfuric acid concentration to prevent over-etching during desmear.

Avoiding Delamination Due to Moisture Absorption-

High-Tg materials like Shengyi S1141 PCB can absorb moisture if not stored properly. Before assembly and soldering:
