Hello, My company is looking at the possibility of bringing in an SPI machine. I was wondering if anybody can advise me on what I should be looking for, and questions I should be asking to evaluate different vendors. I know of two different technolo

What is the reflow temperature you use to attach this package to your PCB.? I did extensive study on this package and compared it with other packages. I used our own Moire Interferometry, SEM, EDX studies. In my opinion the problem is TI does not man

We've gone through this a couple times. Once it was because the device was warping in reflow. We confirmed with shadow moire that the corners were lifting up. The supplier fixed some things in their molding process to reduce the warpage. Another

We went through this with one PBGA supplier recently and they were able to get the problem under control by fixing some of their molding processes that were inducing residual stresses. You can really see it in a thermal moire where you measure warpa
