Intel had a similar problem with one of their military packages. They had "dull" leads. QC screamed loudly about this because the "dull" leads looked like a solder-coating problem. (Actually the solderability was equal or better than the "shinny" lea

please send me a copy of sample reflow profiles for BGA packages. Please indicate the type of BGA and the Oven used. As well as any special characteristics of the assembly that have effected the profile. I a trying to learn more about the common "t

A more efficient and cheaper way of reballing bga's would be to use the Solder Quick bga preforms made by Winslow Automation. It is a very simple process .I've been using it for over six months and it works fine.They have a website winslowautomation.

What we did was design or panels with routed out edges held on by tabs. This was very effective. All we use is a pair of pneumatic scissors to cut off the tabs. We are using from single-to 13 layer PCB's and we have had no problems with delamination

My company is just beginning in SMT. We are using a glue and wave solder process to build mixed technology boards. Our components are mostly 1206 and 0805 chips. The designers are wanting to use 0603's on an upcoming board. I'm concerned that the

Currently i am producing a board using dloble reflow process. The bottom side is mostly 0603 chips and some SOIC. The top side is mostly QFP and some heavy component. During the double reflow process , the capacitor chip on the bottom side drop(same
