Difficulties in the pressing process when producing Flex rigid PCB:

The superposition of multiple core plates and PP (cured plate) is prone to problems such as delamination, sliding plate and steam drum residue during pressing. In the structural design process of the inner layer, factors such as the dielectric thickness between the layers, the glue flow, and the heat resistance of the sheet should be considered, and the corresponding laminated structure should be reasonably designed.

Recommendation: Keep the inner layer of copper spread evenly, and spread the copper in a large area without the same area with the same balance as PAD.
