gsmaster Posted May 10, 2004 Report Share Posted May 10, 2004 The green thing is insulating material to protect the copper from humidity and corrosion Quote Link to comment Share on other sites More sharing options...

MP Posted May 10, 2004 Report Share Posted May 10, 2004 FlipFlop, the material you see on the boards is called solder mask. It is cured at about 300 degrees F after it is silked onto the boards. Normal quantity is 5 gallon container or larger.For the hobbyist, you can get a similar spray on material. I have seen it at www.pulsar.gs in the past. I am not sure if they still carry it, but if not, an e-mail to them might send you in the right direction.MP Quote Link to comment Share on other sites More sharing options...

audioguru Posted May 13, 2004 Report Share Posted May 13, 2004 FlipFlop,In addition to stopping corrosion of traces, the solder-mask saves manufacturers the cost of extra solder and its weight in the product. Quote Link to comment Share on other sites More sharing options...
