I realize this is a SMT forum, but I have another problem related to electronics assembly and hope there will be someone out there that can save my life (this time). We build quite a few VME assemblies to which we attach a SAM board. Fairly standard

Shy: You say, "I've already done some evaluation to reduce the heigh of the glue but it fails at wave solder which cause the component to be drop/missing." Based on your evaluation, questions are: * What is the relation between component standoff an

I have seen tooling cause cracked capacitors.....are the plastic standoffs compliant???? If they are not.....this could be the cause....

Wouldn;t the glue hold the part up?, usually a glued part has much higher standoff than a soldered one. Russ

Shy: Oh, we NOW understand what you're asking. Sorry to be so dense. We agree that the standoff of component from the board could end-up being a little heigher than the pad height when using chipbonder adhesive. We rarely see a problem.

We do not paste when we glue. We glue components so they will stay inplace during wave soldering. In wave soldering there is ample solder to bridge the standoff between the component and the pad.

Hi: I'm looking for input from anyone who has experience assembling the MLP package on PCBs. We are experiencing solder opens after assembly, and I'm curious to see how others are processing these critters. The part we are using is a Semtech SH3000
