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

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

We have seen this problem before. We have ALWAYS found it to be a board vendor issue. Also, we tend to see it more during the summer months. Our solution has been to bake our PCBs @ 50 deg C for 1 hr prior to use. We use immersion white tin board fin

Hi There is a Benchtest on the EPP Stand at the SMT Hybrid & Packaging exhibition that may be on interest to you where 11 printers are going to be tested against each other. It should be interesting to all who are looking to purchase a screen printe

I have bought an old SP-2400 screen printer, very cheap. I have "repaired" it from my best knowledge, replaced all pneumatic tubes that were in bad shape, replaced some logic in the "controller", and changed it from 110v operation to 220v. Well, to

Does anyone have an easy way to estimate how much solder paste is applied to a smt pcb? I understand it varies on squeegee pressure, stencil thickness, and pitch of the components but I was looking for an average. I would assume that somewhere out th

We had some materials management brainiac insist that every component of a product had to have an exact quantity stated on the BOM so we had to weigh every board with and without paste printed. We rented a 4 place digital scale, weighed 5 of each boa

Just trialled some NXT nozzles from SMT Xtra - very impressed by the quality of them, I would guess that their CP nozzles would be of similar standard. Had mixed results whilst using Metro nozzles for CP6 equipment, found lengths varying etc. You co

Well if you are getting bridges under, one thing that we used to do was flood the part with flux and then run it back through the reflow. Keep in mind we were not a High reliability manufacturer. This practice didn't hurt OUR boards, and most of the
