The quick frame does work well with the DEK 265, but we feel that tensioning is user dependent and introduces variation into the process on an operator to operator basis. Also, because tensioning occurs only on two sides (instead of four) this also i

When you say well designed for wave, does that include "extra" solder pads for the IC's for solder thieving? And Boards that are well designed for wave don't have QFP's on the bottom. They might be ok but then the board would be "ok for wave", but no

Assuming all things are equal (attention to good DFM guidelines, well trained and capable operators, well maintained equipment, etc.), which would you expect to have the higher process yield, standard SMT/through-hole all topside, or all SMT bottom (

There is no standard. If your boards solder well, they're good. Well soldered boards that have been stored a long time will have field life similar to well soldered boards that have not been stored a long time. The solderability of boards depends

We have been using Tape and Reel on our GSM for the SOIC-8 packages for a while, and it's working pretty well. Less operator error, less reloads, less jams (provided you take good care of the feeders) and LESS TUBES STUCK IN MY VCD SEQUENCER!!! I hav

Just learned today that Humiseal will no longer be producing their HT-500 masking tapes or dots. Bummer, because their tape worked very well and left no residues even after baking. They say it was becoming so hard to get the raw material for their

My plan is to remove as much of the parts as possible and reuse them. Once removed I plan to fix the baord as well. Now have a fresh board to build too.Just about every part can be reworked these days. Even BGAS. Most boards can be redone so that

We use a small surface mount connector that has two alignment pins to ensure proper alignment. It works fairly well. I'm thinking that this simple alignment solution might work well with lead less parts like a BGA or QFN. I can hand assemble QFNs

Ask for board fiducials if you're running arrays. Global fids on the panel do not work well. One handy product we use on flex is "Tacsil". Works well on SMT pallets as well as router operation. It's double sticky stuff that helps hold on to the P

Tom, I use the same Fuji machine you are referring to. The company that I use is ibe smt. Alex Dalgleish and Larry Johnson both are very well versed in these machines, and they stock parts for them as well. I have never had to look anywhere else f
