Hi Bob Ideas to consider are: * Use your handheld XRF * Swab vinegar on the copper and watch it brighten * Use the following procedure Nearly all copper minerals can be dissolved by melting with a mixture 1:2.5 of ammonium chloride and ammonium nit

If the batch cleaner is truly closed loop, then 100% of all of the process fluid (water) is captured, filtered (particulate, carbon, resin) and reused. This answer is based on a traditional closed-loop batch cleaning system with an integrated water

Thanks for the reply Stevo...! I am looking at doing just that. I would really like to ID this component and repair this Pico board though... After several searches, I can't find any (3) element resistor or capacitor networks to match it. I'm hop

More and more PCB fabs are switching from chemical copper to what is called a "black hole" process from McDermitt.In this process a very thin layer of carbon is put on the base material instead of chemical copper. Can anyone tell me about the advanta

| It looks like a great memory machine, but the thruput is cut in half when running typical SMT boards. | Ya but all gantry machines run at half their highest rated speed in "real life applications." That aside, on paper, this looks like a good mac

Is there any problem using SMT on gold boards? 15 years ago we were told not to use gold boards, but I can't remember why. Judging by the other postings it now appears to be common. Only problem I see is that the nickel should be plated, not elect
