Electroplated nickel and electroplated gold is the more �traditional� finish for aluminum wire bonding. That surface was an extension of gold thermosonic wire bonding that requires a thick [50 thou min] gold surface. For years fabricators recommend

The alternative is by looking at all your components data specs (heat-range), especially pay more attentions to heat-sensitive comps, and fine-pitch comps, odd-form comps, draw a diagram on a separate sheet of paper shown that temperature VS those ca

I have found that during the interviewing process you need to include your technical staff to get to the nuts-and-bolts of what your looking for. Plus, team involvement spreads the responsibility for selecting the "right" candidate. Recently duri

The problem is that we don't use a wave solder machine. Our process right now is that we mask the holes, let it sit at room temperature until it dries, then conformal coat the boards with Humiseal. And, we cannot have the boards ready the day befor

Back in the day, we had a small solder pot used for dipping ICs that were freshly removed from defective boards. What tool did we use to clean the dross? A small piece of card board. After the card board got too toasted, we'd grab a new piece of c

Couple of things. Type T thermocouples are solder friendly. However usually a header with screw terminals poses no problem as the temperature differential is nil. Getting thermocouple leads wet causes problems because two dissimilar metals + condu

On first glance it looks like those particular pads were not attached to any traces. If I had to guess I would say that your rework profile got hot enough to melt away the glue holding the pads to the board and they came away with your part when you

The budget is tiny, I agree. It is more to get our feet wet. We are mostly afraid of adding more steps in the process thereby making it more difficult to implement. I want to avoid a wave soldering machine and also want to avoid making two passes

Sorry Bob Could not respond been away busy. Just to correct you, we did not copy the SACX as we brought ours to market at least six months before so how could we copy, it is also a little different, but nicely reassuring when the 'big boys' do some
