PCB bent due to mechanical force | 15 May, 2019

Can we bent a PCB using mechanical force ?Will the PCB come back to original condition or it will be bent forever after the mechanical force is removed from the pcb?

If you are trying to remove/reduce warpage in the PCB (I am presuming) place in heated environment (170 F) for 24 hrs with weight on it to keep it flat. Has helped us in the past.

Look up the glass transition temperature (Tg) for the PCB material. If you get the PCB above this temperature it will become quite soft. If it is a populated board remember to take any moisture sensitive devices on it into consideration.

This issue is seen at mechanical process.The pcb is thin 32 mils.Can we bent it just by using mechanical force without the heat?or the pcb will break if the force is high instead of becoming bent at one corner..
