Multilayer circuit boards, with at least three layers, are complex to manufacture, require precise design using Eagle software, and offer benefits like increased density, reduced weight, and better performance compared to single or double-layer boards.
In general, the pressing process does not affect the bonding force between the copper foil and the substrate in the laminate, but contamination or damage during lamination can result in insufficient bonding and poor peeling strength, leading to potential copper wire fall-off. In addition, the use of poor quality foil or mismatched copper foil and resin can also lead to inadequate peeling strength and copper wire shedding.
Prepreg must be carefully oriented during lamination to prevent post-lamination warping, stress relief and straightening processes are crucial for PCB thick copper plates, and warped boards require baking and pressing for salvage, highlighting essential anti-warping measures in PCB manufacturing.
