The ICOM 5000 was made by Trek Industries. The company was purchased by Stoelting. I don't think they make or support these machines anymore. By the way, the correct formula for area is Length X Width X 2 (X 1.3 or 1.5 based on component geography)

Your understanding of the situation is correct. In both cases, you solder to the nickel. The gold [Au] protects the nickel from oxidation. When soldering, the gold moves into solution in the solder and forms an intermetallic compound [IMC] with th

Because most placement machine mfgs' feeders vary in width sizes its best to get the reference from them. Like how many 8mm slots does their 16mm consume, and so forth. Std. Sizes I've seen are: 8mm, 12mm, 16mm, 24mm, 32mm, 44mm, 56mm, 72mm, 88mm, 10

First, �flash gold� is very loose language. It means different things to different people. �Flash� gold is a thin coat of immersion gold. Imm gold self-limits at ~0.3um[12uin]. And fabs put-down �flash� prior to electroplating thicker gold for wi

For a typical wear surface application [millions of wipes], I agree with hege. You need to be talking electrolytic gold, NOT immersion gold. IPC-2221 says something like ... For edge connectors and areas not to be soldered: * Nickel - 2.5um [~100uin]

It is a little bit sad that I know this - be prepared for some confusision - this is not as simple as it might seem. Something tells me that the calculation of the tolerances for the nominal dimensions is a little inconsistent. As I recall the defa
