Also I suggest you read through the Charity Report I produced on the specifi process of Double Sided Reflow Assembly which you can also get from the SMTA. All the money from the sale of the report goes to the Charles Hutchins Scholarship Fund which T

A couple of weeks back I produced a video clip for Metcal to show what happens when BGA pop or the edge of the base warps causing shorts to form. Its 2.3meg if there is enough interest in seeing this I will put it up some where for download. Bob Wil

Ver: The best thing I could do is send you to Bob Willis' site (www.bobwillis.co.uk or something like that), suggest that you root-around there and find one of his procedures that will help you, and come back and we'll refine your process. Good luc

Check Bob Willis' site. He calls this Single Side Multipass Endothermic Elongated Happy Reflow Soldering, er someting like that. Ha ha ha!!! Naw, he calls it Simultaneous Double-Sided Reflow Soldering. That might be something like you are talking

SMTNet has a video tape and interactive CD ROM on Intrusive Reflow Soldering that you may want to check out. In addition there are some free inspection standards for pin in hole printing, placement and soldering available at http://www.dpmo-monitori

I have had a look at what Bob Willis say's and the answer to my problem is not there. The paste we are using has a very high viscosity and I beleive that if we reduce the metal content to less than 90% it will solve the problem. The problem is parti
