Assuming you've already looked at optimizing your profile and stencil design, have you looked at metal load in the paste? I hadn't, but just read that increased metal load (associated with reduced powder size, i.e., moving from T3 to T4) has been sh

Zack, circles 36mil copper 35mil circle stencil aperture. Pitch is 80mil. Stencil is 5mil and apertures are spread 46mm under the 50mm component size. In my mind this might be too much paste. I am afraid that if I print 4mil I might get open joints

Yes, you may need tell us how the PCB designed, how it re-flow(even it's Indium voiding formula), how stencil is. The void ratio means area ratio, not diameter ratio, so you need calculate it. If you have high ratio void, show its picture.

Hello, When I calculate based on the data you gave, your stencil aperture area compared to pad area is 94.52%. Your aperture area ratio is 1.76 using 5 mils thickness foil. OK, your stencil and your paste release is not the culprit here. Your proble

I would recommend quik-tool. Jim Bernhard essentally the inventor of Grid lok left when they went to DEK. Started quik-tool, we use grid-lok in our printers, quik-tool in our Panasonic P&P instead of support pins. Like quik-tool alot more. JBernhard@

haven't tried the MINT as it won't let me get that far !! Swapping the Eproms with card 1 and changing the identifier will let it get to the 'Press SYSTEM key' part of the startup though, then it fails on card 1 instead of 0 so I'll give that a try i

Hello, I recently purchased a Hotflow 3 oven, using a step up transformer I received with unit, 220v to 480v. Unit turns on but does not heat up. Getting an F02 error saying no convection. I am getting 480v to oven, I also switched the phase still
