| In the early days, we used screens made of stainless steel or polyester. Sometimes - after A period - the tension was not good, because A wire was broken. | Later on we started to us metal stencils, glued in A polyester screen. even than we had som

We are using the Universal tooling..the one with the side plates. I'm not sure what the C-tool is. The machine did not come with much. I'm running the vision system test now..I've never done it before..but I'll let you know what happens with it. To

about WHY violating IPC design standards gives you grief? Do they even know they exist? We've got one in particular that seems to shoot from the hip. I want to tell them the "why" as well as the "what" so they'll be a little more proactive. My fee

Since we are on the topic, What we do over here, is to get SMT Technical to machine pick&place "sample component layouts" onto double-sided tape, which in turn is placed onto an actual PCB... QA will take that double-sided tape sample, and using an

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

Continuing, I�ve optioned about the uselessness of shear testing of solder connections on this forum previously. So, the points that you make about the elusiveness of developing a standard for measuring solder connection strength is well taken. I�l

They key requirement before any fancy tools is careful storage, stock control, labeling and handling. If your parts are incorrect before they even get to production, you're screwed. As gregp suggests, to get consistently correct value and orientation

| I am looking for more information about: | | 1) What kind of evaluation can I do to measure the resistance to fall off of a bottom side glueded SMT component?; | | 2) There is some influence of doble wave solder machine (temperature, flux, etc) i

Russ, As I stated earlier 100% satisfaction guaranteed. I'd like to address a couple of your problems. 1. Lack of TC control. I don't really understand this issue. The system is a closed loop system w/ the TC located directly in the nozzle block.
