Q1) How to identify on good or bad RF shield that could contribute to dewetting? A1) We use Alloy 770 and 752 [German silver] for our RF shields. We have never seen a solderability issue, even aged stock solders well. * Nickel Alloy 752, Nickel Silv

Assuming that you have a saturated moisture-sensitive component: At what temperature would popcorning or internal component damage occur? I would guess that it would be at a temperature where water would boil, around 100 degrees? However, the JEDEC J

Thank you ENIAC for your comments Here is another problem (JUKI KE-750L) Which applies to 0603 (1608 metric) resistors and only resistors (mind you the board is more heavily populated with resistors) After the panel has gone through the oven, Wh

If your silkscreen is too close to the toes of your leads, you can bring the lead bank inspection box in a little bit to compensate. I haven't had many issues with tantalum caps. I inspect those under white light with no filter just fine, but then

We do in fact see a reduction in soldering defects, most especially wetting issues for both parts and PWBs, tombstones, billboards, etc... As a CM we see all kinds of customer furnished material, some of it not in the greatest condition. Our best p

I meant more from the programming perspective, make sure you make the most of what you can do with modern computing interfaces. Making configuring/creating jobs etc as accessible as possible to as wide an audience possible. As an example look at how

Sorry for delay - been flat out. Sr - I understand what you are saying. My concern is that combined with the head offsets and variations in pick points (i.e. having to teach feeder positions for very slight amounts like 0.05mm)then you cycle times wi

We manufacture low volume, high reliability assemblies (class 3) that are conformal coated. Up until now we have been cleaning after SMT, then after through hole, then immediately prior to coating with test, formal inspection, etc. between cleaning p

I’m setting up an RF and mm-wave lab in a university. My idea is to purchase a set of machines using which I can do pcb prototyping, solder pasting, picking and placing the components (the smallest footprint would be 0201), and soldering (oven). In a
