Mark, that would be a good report to have a look at can you post it on the site or mail it out to me? Also I've been having an issue with blue peelable solder mask on silver boards where it peels the silver off with it. I've only seen this since my v

Mark, I am having difficulty picturing exactly what you are doing, but I hope this helps. We occasionally use jigs through SMT, usually because the board is too small/thin to fit the smallest rail width. In such situations, we normally make the jig

I think you are going to struggle without a laser designed for PCBAs (Asys, XJ Link etc) as they are designed to just burn into the resist and give good defininition, then readback to know you have a good mark. Key tips for our experience: Datama

| Our vendor proposed to supply us with shields made out of Cold Rolled Steel (CRS) electroplated with Sn (50 - 150 minches). Should I be concerned with solderability or are there a better alternatives to tin finish? | No matter the base metal, elec

This provides LT 3 misses /1M hits. * Probe all points on one side of the board. Bonus => This lower fixture cost. * Test pads and vias: GT 25 thou from other land traces. * Small [LT 5 ohm] resistor measurements: Use two pads at each end and do 4-

We had x-ray and optical microscopy analyses done on transformers dip soldered with Sn/Pb, SN100C3 and SN100C4 alloys using temperatures 400�C ... 450 �C, with dip times of 2..4 seconds. We found that SN100C4 is at least as good as Sn/Pb 62/38 and SN

Bismuth is a low-melting metal with poor mechanical properties; if you melt the bismuth wire into a standard tin-lead solder joint, then the bismuth alloys with the solder, and forms a material that will crumble if you scrape it with your fingernail.

Would be glad to offer some assistance, but I've got a couple of questions first: 1) What type of supplemental flux are you using? (If any) 2) Is your problem consistent across all assemblers, or can you trace the assemblies with solder ball issues b

No we have a battery spring that is soldered directly to a PCB (standard tin plated copper PCB). The Battery spring supplier (and I have no confirmation he makes them or buys them) claims they are tin plated. When trying to solder to them it is very

Hello, I am looking for the name of a type of connector that connects wires on one side and simply slides on the side of a PCB to connect. The PCB has copper lines on the surface (so no connector part rigidly mounted to the PCB). Can anyone help me
