I'm looking for information from both those who do cure glue and reflow past with the same profile and those who have tried and decided against it. What were the problem? What are the limitations?

Has anyone had experience with placing BGA on gold plated boards. I thought I read a while ago there was a problem with embrittlment causing cracked joints. If anyone has experience with this your feedback would be great. Mike

I have heard that there are problems using immersion gold on PCBs when working with BGAs. Is this correct? Is white tin more suitable?

Howdy Jack, That is a huge request, It would help if you start from the begining of your process and break down the problems that you are having.

Solder balls with wave soldering can have different causes. The two most important are the solderresist and the flux. I have similar problems, after changes the flux type 90% off all solderballs are gone. KR, Joris Groot koerkamp

Hi Bert, For your second issue, are the tools well lubricated? If not the Midas head can fail to grab the tool and can generate the z motor error. Doing this followed by a base-centre level measurement should resolve your problem. Steve

We currently do have part system in place. The problem that we are having is finding the same part used on multiple jobs. We it be sufficient to keep most used and common parts on hand. Then turn kitting into fifo.
