I recently picked up a used GSM-1, 1994 or 1995 vintage. I'm in the process of setting up my first product on it - everything seems to be going well, however there's a constant inch or so offset on the X-axis. That is, when the board slides in, it'

Does the pcba:s comes directly from the assembly line, You are going to do rework on? If faulty pcba:s comes back from, let say a customer from outside or the pcba:s has been on Your shelf for some days/weeks, exposed to open environment (humidity in

Quad/Tyco should have some old 'q-tips' on programming help for that type of board on a 'c-series machine'that i wrote a long time ago. I cant remember anymore exactly how to help you but they should have some paperwork on doing it. It also is a 'sli

Guys, I have a 2.4mm pcb 8layer with a lot of copper on board. I am having some problems with solder not travelling up through the holes. Looking from the bottom of the board it looks fine . Also, To measure temp. of board through preheat zones

Some causes of lack of top side fillets (hole fill) are: 1. Not enough pre-heat (a top side preheat will help, if no-clean flux, be sure to follow flux mfrs specification for top side board temp just before hitting wave) 2. Not enough flux 3. Flux i

In addition to Pete's fine tips, here's one we have successfully used in similar situations as long as you're using OA flux. Get some kind of pump action spray bottle (like hair spray comes in) and fill is with some of your wave flux. Use the bottl

The soldering handbook that I use gives a 'rule of thumb' for best preheat temps for wave soldering. For multilayer brds that are metal core it suggests 110 to 130 degrees C topside temp to get the best solder fillet. We do a lot of multilayer meta

Bob, I've heard that many WSM manufacturers are not providing warranties for stainless steel solder pots that are holding SN100 because they are not completely confident that the SN100C alloy is non-destructive to the pot. fct�s own webpage states

Hello Pete, Do you know how long Electrovert warranties their coated pots/pump equipment in use with SAC alloys? Also, does the warranty cover an operator scratching the surface while cleaning the pot in normal maintenance procedures? The good news
