PCB manufacturers tell you how to increase the resistance to deformation of the circuit board

PCB manufacturers tell you how to increase the resistance to deformation of the circuit board


1. Use high Tg PCB material. High Tg means high rigidity, but the price will increase accordingly. This must be a trade-off.


2. Increase the thickness of the PCB circuit board. If you can, it is recommended to use a circuit board with a thickness of 1.6mm or more. If you still have to use 0.8mm, 1.0mm, 1.2mm thickness boards, it is recommended to use furnace fixtures to support and strengthen the deformation of the board when passing the furnace. Although you can try to reduce it.


3. Pouring Epoxy glue (potted) on the circuit board. You can also consider pouring glue around the BGA or on the back of the corresponding circuit board to strengthen its stress resistance.


4. Add steel bars around the BGA. If there is space, consider building a house with a supporting iron frame around the BGA to strengthen its ability to resist stress.
