I am wondering if others are seeing the same issues, and how you are dealing with it. I have found more and more datasheets that no longer have the "Part Marking" indicated. I say no longer, because I have managed to find a few older revisions of th

For the past year now we have been printing adhesive with no real problems. Our printing ranges from 0603's to SOIC using a variation of aperture sizes and metal thickness foils. The crucial parameters are : aperture sizes : These obviously depend o

Now that's surprising that your board fabricator would say the mask was cured properly [without even inspecting the boards]. I wonder if they can backup those BOLD words when testing your boards with the webbing problem. The reason you can�t find t

I have never seen excess tin [heard of it, just never seen it]. Excess lead yes, but tin no. See, tin oxidizes faster than lead. This means that dross has a higher tin content than the solder in the pot. So, with a very high dross machine, we regul

Mike, I understand your dilemma very well. You see, I was a manufacturing engineer for 11 years doing make or buy decisions before getting into the sales field. But for this commentary I will wear my engineer hat. Your situation is not uncommon.

Hey Brian, We are not sure what it is you are referring too? If you feel they did not respond promptly than I am assuming that you picked up the phone and asked them what's up? Your thread just came across as bashing and a little negative, as

| I finaly get a vacation and decide to go to the forum and low and behold it's hot air verses a small ray of sun.I read every thread and still failed to see any real argument either way? I love rework as an assembler. I hate rework as a shop owner.
