Flexible PCB manufacturer tells you What PCB finish you should use？
Once a printed circuit board has become warped, it is nearly impossible to fix. Thus, the best method for fixing PCB warping is by mitigating risks that cause it from the start through smart board design, as well as an understanding of the importance of thermal management in PCB manufacturing.
As PCB supplier china knows that，PCB is Metal Core Printed Circuit Board, that is, the original printed circuit board is attached to another metal with better heat conduction effect
As PCB manufacturer China knows that, Printed circuit boards can become unusable after warping too much.
How to distinguish the number of Multi-layer PCB layers
FPC board production process
From the analysis of the basic structure of the flexible printed circuit board, the materials that constitute the flexible printed circuit board include insulating substrates, adhesives, metal conductor layers (copper foil) and cover layers.
The quality of solder joints is very important in SMT (Surface Mount Technology) Health care PCB assembly.
Printed circuit boards can become unusable after warping too much by FPC supplier. However, every single FPC will show some degree of warping due to the nature of their manufacturing process.
Compared with other SMT processes, the solder paste printing process has more variables and potential instability. The printing process has a variability of more than 60%.
