Gel flex is crap! If you put enough in to actually support the board, it bows. Apparently MPM knows this because they include hard pins with the set (kinda defeats the purpose huh)! I trialed the grid-lok and it worked fine and operators loved it. Th

JNJ made a nice tooling plate for MPM Hi-E series. Its intent was to replace MPM's "Universal Nest" with an alpha-numeric grid type system. I looked on their website, and they don't make it anymore. Worked great as long as you documented your setu

Well see you wrong. I've done this kind of thing for 12 years and I cna tell you that suporting boards with anything else will cause more problems. wave is an art tha needs to be respected even by engineers at AI. Once you get the process down the

Hi Steveo, What sort of products are you using the vacunest on? ie: PCB thickness, panel size, complexity etc... What brands and types of screen printers are you using? - Did you have to modify your printers? Do you also use it in your placement

I know this is not SMT related but would anyone care to comment on Alpha 856 flux, good/bad experiences or any known issues? I did some samples recently using it and had excellent results. Information on it seems a little hard to find and it makes

We saw something like this in the machine shop years ago. Fumes from a soldering operation in the shop turned exposed iron and steel tools and the spindle on my Bridgport mill green. Can your supplier apply plating or a coating to the exposed parts o

No problem. If you get no joy you're going to have to change the footprint to a 1206 or 1210. Murata have a range of high Q value inductors (50-60) & from memory Toko used to be pretty hot too. The terminations on the coilcraft part are listed a

with lead-free solders, one would expect to find less instances of tombstoning. this is because SAC alloys are not eutectic and melt over a range of temp (usually 217-220 deg C) instead of at a single temperature. therefore the forces due to solder s

Hmm... how about the people inside this room; working in this dry environment? This is something never discussed highly, but I believe it is most certainly important for the human health. This is another interesting thing about RoHS; the side effects
