I guess I asked the wrong question. For an OEM that builds electronic equipment that is used by industry in the production of pc boards, what specification(s) should the OEM be meeting for electrical safety? I have been given some paperwork that ref

If this is a requrement from your customer then: They should supply the name/brand of the material, AND they must supply solder samples because their requiremnt is a destructive profiling technique. You should charge them more dollars for setup and

DI water de-ionized water is an easier way to ensure washing free of contaminates. De-ionized water has a characteristic resistance of 18 meg ohms per cm squared. Resistance monitors can be installed in cascading wash systems that would monitor conta

GerberGrab does exactly this, and it's low cost, and you can use it for a month for free. It is a sophisticated but easy to use reverse engineering tool which will automatically generate top / bottom BOMs with placement and rotation after teaching of

Hello We are using a No-Clean process for a lot of boards that we do, but the customer needs the flux removed off the bottom side of the board and there is to many leaded components that can not go through a water wash, so is what we do is clean th

I'm working on a new product soldering to a thick film material. We currently use only No Clean solder pastes. The vendor that supplies the substrate has suggested going to an RMA paste to improve solderability. We haven't used any, but I'm not fa

I have recently encountered a new pcb design with a very high density of components on either side of the pcb. One of the suggested "fixes" is to use the smt pads as vias i.e. the via will be drilled thorough the centre of the smt pad. My concern i

We are asking $10,500us for this machine, as for shipping I will see what I can come up with as we are in Canada. This is a dual wave machine with foam fluxer. It has not run in 3 years but when we had it in production results were favorable and cons

I have used tooling holes and fiucial registration since the late '80's. In fact if your maximum "vision" tolerance is +/- 0.05mm, your in the same ball-park as locating pins. It is true that fiducial registration is more accurate. However, I woul

We currently use the bartector system on our CP6. It has saved us quite a few times with wrong part numbers being loaded on the wrong location. (rework for certain parts would have been a nightmare) It is extremely easy to use. I was not involved
