Used for "reballing" chips. These precision-cut metal sheets allow a technician to apply perfectly uniform solder spheres to the bottom of a BGA (Ball Grid Array) chip.
Disclaimer: Always follow ESD safety and manufacturer guidelines. Conductive epoxy is not a substitute for solder in high-current or high-frequency applications without testing. pcbrepairtool
Connect the power supply to the board, but limit the current. Use the pcbrepairtool to generate a voltage map. Look for the component that is unusually hot. Used for "reballing" chips
Heat is the primary mechanism used to solder and desolder components, but it is also a double-edged sword that can damage heat-sensitive silicon or delaminate the fiberglass substrate. Conductive epoxy is not a substitute for solder
To get the most out of your , avoid these pitfalls:
If you work in electronics repair, you know the feeling. You’ve got a multilayer board on the bench—maybe from a medical device, a laptop, or an industrial control unit. A component failed, but when you removed it, the pad lifted. Or worse, the via pulled clean out of the inner layer.
