Muse, I agree. There has been much debate but the previous scenarios discussed in the forum have been regarding the SAC/RoHS BGA and Sn-Pb paste. I have successfully collapsed a SAC BGA with a Sn-Pb paste using the "hybrid" profile that Amol refers

Pat, Try to run a glass plate (yeah I've used these before too), keep your wave pump speed the same, and slow down your conveyor speed. You will find the actual contact between molten solder and the 0.5" grids to be LESS vs. a faster conveyor speed

I'm just wanting something solid to show my workplace. I am under the belief that it is a flattened coined lead. But like how i've been trained in IPC, I have to be able to prove that it is true... or that IPC says it is false. We have a customer tha

The surprise to me with this entire post is why CyberOptics (USA) has never come up in this conversation. The new SQ3000 will change the 3D AOI market for the better with their MRS technology. I have witnessed the image quality from this new sensor

| | We are anticipating switching from RMA to OA flux for both reflow and wavesolder in the next few months. If you use a batch cleaner running DI water only I would like to hear your experiences. How is it for cleaning under low standoff component
