Thanks Dave. Talked to a few people at APEX this week and if nothing else, had my frustration reduced some. Of course I made sure I talked to mfg. people and avoided the design guys like the plague. ;) I actually picked up a copy of 785 a while bac

| I'm having problems with trying to get a good solder joint using a Ceramic PCB. We are using AMTECH hi-temp solder (ws-486 96.5/3.5ag). My profile looks great and I used the recommended profile from Amtech with a few adjustments. My max temp is abo

| | Hi, | | We are having problem with yield loss due to electrical fail. Further investigation shows that the failure is due to solder bridging under BGA. Has been there any study or experience on how this could occur and what we can do to prevent

| The question raised by our components engineering group is, is it possible to tell whether these failures are thermally or mechanically induced. The focus of design engineering up until now has been on process. Are our reflow temps ok, are the pa

Is this a sample board that you ran without components? If so, I'd get it back to your board house, and ask them to explain to you what's happening. We never did get to a satisfactory root cause on our issue (at least, satisfactory to me). It seem

| | | What approach do you you use to reducing wave solder dross? What is your experience with Klennox? | | | Dave F | | Klennox should be spelled Kleenox. Dave F | Kleenox works well for removing accumulated dross as it separates the dross from t

I have read many of the past threads on both topics and I still am not convinced I know the answer to the soldering problem we are encountering. I am hopping someone can help. I have a dense SMT board we are building and have been building for some

I have recently signed onto a company with very little board assembly experience. I am trying to develop a process control and continuous process improvement program for a new surface mount line, but have run into several people who are not really i
