Just heard yesterday from my KIC rep that they have a product called KIC vision now. Sits in your oven and does the profiling automatically whenever you tell it to. They also have one called KIC 24/7 which can profile (and assign a PWI) to each board

I agree, the level of Pd plays a role here. Knowing that some versions were probably OK we tried to develop a soldering test for PdAg components with pass/fail criteria, but decided it wasn't worth the engineering effort for a finish that's so rarel

Check out http://www.solderstar.co.uk/wavePro.html This tool measures all key wave solder information with a single pass. Wave/PCB contact, immersion depths, etc. Also has a reflow pack to allow use on reflow, 9 channels with predictive software. B

Hi, We have had a few vendors push automatic solder paste inspection devices on us in the past, and I have resisted until now. However we have a new product with a micro BGA on it, and I am worried about yield, so am considering it seriously for th

Does anybody have any reasonable experience with an in-line Solder Paste Inspector that actually is inspecting 3-D solder paste? Does the information that you get provide any reasonable data on process control (not just pass/fail) that would justify

Do you specify copper weight on your boards? This could be the difference between the the boards. Also the finish will be different between the boards as well. These two factors are enough to cause bottom side parts to reflow and fall off. In eit

Use of a hot air gun to reflow solder that passes tests [after failing those tests] seems to indicate the standard process reflow was inadequate. To understand this better, we'd want to measure temperatures at various points on the board during reflo

We have used good industrial dish washers in the past. We washed very dense SMT boards with mulitiple BGA's. they always passed Ionic tests. You can buy these for as little as $500. The less expensive ones won't hold up to 140F water and suponifier b

I don't know about that machine but 5000 wouldn't suprise me. And make sure your targets is less than X false fails with zero false passes. I can probably get zero false fails with any machine but I"m sure a lot of defects would get past that machi

Colorization is relatively uniform across the board. "Processing" is first pass reflow. I belive MacDermid is the ImmAg supplier. Plating thickness has not been determined, our XRF is being revitalized. Elemental analysis did show a large copper
