Tips for Rework of Large Scale BGA Components
image
You've just been given a board with a shorted BGA site. If management decides the board is worth salvaging, there's only one thing to do; remove the BGA component, clean the site, paste the site, and replace the BGA. You've done this many times before, but still, as any one who has attempted BGA removal and replacement knows, BGA rework at any level can be finicky and challenging. Yes, it is complicated enough, but in this case the challenge is magnified as this BGA component has 2600 balls at 1.0 mm pitch ...
Feature Story
BGA BAll Sheer Testing
Ask the Experts
We soldered a lead-free 548-ball BGA. After reflow, we mechanically pulled the BGA component off the circuit board surface. In some areas the pad was ripped off the circuit board surface and remained attached to the BGA ball. In other areas the joint sheered at the ball/pad interface. What should we expect to see? Should all the joints act the same way? Is one attachment result better than ...

Watch a short video that shows our robotic BGA component reballing capabilities. Our high-reliability BGA Reballing service can quickly rework BGA components that require reballing. Reballing is most often required when the alloy of the BGA component solder balls needs to be changed from lead-free to leaded. Every BGA Reballing project is completed to meet IPC and JEDEC specifications.

Base Board Burn Repair - How and Why
image
Cosmetic surgery is big business today, but our discussion here is not about face-lifts or tummy tucks. We're concerned with the cosmetic touch ups we must often apply to circuit boards. While we're all familiar with reworking components, repairing pads, adding jumper wires, and the like, we have been talking about the practical application of repairing or restoring functional circuitry. What about repairs to the non-functional parts of the board? Are "cosmetic" repairs even necessary ...
