"...the part is aligned to the pads with in 10% before going into the IR oven." Sounds like the pad pitch might be okay (?). If that's not the problem, then what? I wish I had the answer, because I've struggled with heavy QFPs for some time now (2

I need advices as to how a gap between the bottom of an LED (1209-package) and the PCB can be controlled on a small rigid-flex PCBA? The problem that we experience is due to tight tolerance in the design of our molded housing in which this PCBA is as

This sounds like sales-type teaser posting, but let's see what we get. When comparing convection to IR BGA rework stations, IR stations perform poorly when: * Evaluation board has no power and ground planes. Worst case PWB as IR energy from bottom h

I've used DBA in the past. It's not a bad MRP software for the price. Though, your mileage may vary. We were using an older version of it at my last company, and there was no desire to upgrade. From a manufacturing standpoint (bill of material co

It�s reasonable to want to understand this strange looking fabrication, before moving on to other issues. Before moving on to that, tell us more about your thinking the silicon being from the BGA package. What kind of plastic package is this? Desc
