I know IPC-A-610 RevD has requirements for Gold Fingers and solder contamination. Is there any such requirements for Gold Mounting Holes, Gold Pressure Fit Socket Lands (SMT pads), Exposed Gold Traces ? Wouldn't these all be considered "critical cont

Lead cannot be penetrate your body through your skin by just touching it. You have to swallow it. It does not promote cancer or cause you to go steril like the rumors at my plce of work talk about. Although it is fun to touch people you dislike wi

Why not. He's an easy target, just look at him. Like a deer caught in the headlights. But what do you think about the other info? About the EPA. Did you know that when asked if we could inform other local companies of their policy, they told us no.

This is strange EPA is not out to fine companies but to enforce regulations. We are in the solder and flux business and get audits at least twice a year. We are not perfect (yet) so there are times that we have non compliances. When that happens we g

The rep from the EPA told our director of operations that it can not be faught. Apparently he was really rude and basically said (with his team of over paid lawyers there of course) that the one company that tried to fight one of these fines ended up

This sounds really fishy. But of course we only hear one side of the story. Again the EPA is not out there to fine companies UNLESS everything else fails. You say �The rep also very sternly informed us that we are NOT allowed to form any campaign th

I believe this was a ultra wing attempt to open political arguments. I have had many dealings with the EPA, because the company I work(ed) for screwed up. The EPA allows you time to fix things, will fine you if needed and can shut you down if requi

What techniques do you use practically to reduce rearmament time of SMT line in high mix production ? There was such post on forum about it but I would like to gather all techniques in one post so everyone can add some ideas which are already applie

as most of our components are described in AML list, we can't play with that so much... so we focus on preparing the line tools/materials before the change (paste, spatulas, test pcb) - and Yes all the dressing for Juki is ready, for TCM most of the

We have received in one lot PCBs with defect of not wetting properly. Pads were finished with HASL but they were matte rather then shiny (attachment). For me looks like they are oxidized. Interesting is there was just top side with such defect. We h
