How to check repair mobile short circuit board
An electrical network that has a closed loop giving a return path for the current Printed Circuit broad is made up with Fiber.
Circuit has prints and a wires in copper. If copper prints is broken, It may be repair with a jumper wire If Circuit is burned or damage, no way to recover it.
Short circuit Checking method
Set multi-meter on CONTINUITY
Scenior1: Connect Black probe to Circuit's +VE print. and Red probe to Circuit's -VE print shows some reading.
Scenior2: Connect Black probe to Circuit's -VE print and Red probe to Circuit's +VE print shows no reading.
