Has anyone had any experience with using this alternative plating process? Some board houses are pushing toward this plating. Is there any long term data on this process? Any problems experienced with smt and thru-hole? I've heard tin whiskers to be

Quad still sells a low end convection/IR bench top oven for about $15,000. (ZCR 412B) It is limited to a 12" board but may work for your application. IR ovens have gone out of favor recently. There should be some older IR ovens for under $5,000 f

Hi Terry, I do the same thing Chris is suggesting. I am not sure about the company who made the thermocouples I use but most probably it's the same. I'll let you know if they're different so that you'll have an alternative source. I also agree with

Certain board designs require the unavoidable use of non-plated holes and slots. Presently, this requires a trip back to the drill house to open up the aforementioned holes, to remove the unwanted plating. In situations requiring non-plated holes and

We have a need to bond Flatpack and Quadpack components to the circuit board. The adhesive should be quick curing, repairable and have a low modulus. It does not have to be thermally conductive (but it would be a plus). The components are currently

I have a problem with measling on our PCB's. We saw it on our FR4 PCB's at final assembly yesterday. Is this a defect from the board vendor or something we did in our assembly process when building the PCA's (thru hole). Could the wave solder mach
