I haven't had the luxury of machine based pth assembly in quite a while, but when I did, given that the machines control which parts are inserted (and to a lesser degree where they are inserted) we decided not to perform inspection on that part of th

We need to be careful with product to avoid introducing a new failure mode, namely corrosion and dendrite growth, especially those running no clean processes! In addition to heat (reflow, wave and some selective soldering processes) killing the vi

Hi Ya'll... I'm in here again today trying to deal with my down wave solder. I've been beatin' my head against the wall for the last couple of days, it's a Soltec Prisma and the conveyer keeps jamming. What it's doing is up at the exit end where th

Stuart, My suggestion is a DFM meeting (most of the process people dream about a meeting like this, and luckily, I've been to a few) with: - project manager (if there's one) - customer service rep (annual volume, lot size, product life) - smt proce

Hi, We are encountering a shortage on our parts and our purchasing said that the parts, which is in PLCC packaging, is hard to order from the local and international market and we can only get them in QFP packaging. Now the problem enters here. Our P

Greg: It depends on the specifics of the flux you are using. You didn�t say. Generally, using a: � "No-clean flux" should create no flux entrapment problems for most applications. � RMA with 25% or more solids as a "no-clean" should create no flu
