#PCB Design
I am a mechanical designer. I have sent my PCB design file to manufacturer. But they said the data may be not enough. So what data are you used to send to your PCB manufacturer.
My PCB manufacturer just informed me that he is facing PCB warpage issue in my simple, single sided, copper poured PCB. He says to avoid this issue he suggests to add a dummy copper patch by keeping 3mm copper clearance from all sides. Can somebody tell me what leads to this issue and what are possible solutions to this problem ?
I ordered a TV repair service. It is so costly. Do you have similar experience? Why does it cost a lot?
