Dave, I would have never thought of the sheet metal box. My west coast contact, who has dealt with this type of board before, told me yesterday to go ahead and try it at this profile anyway, as the metal plating holds more heat. I was pleasantly

Larry, You can try one of two approaches, a bake above 100C will drive off moisture or use a vacuum bake. The vacuum bake process is slow since there is less/no air to conduct the heat. In the hybrid industry the standard vacuum bake was 16 hours at

Thanks, guys. Hi Larry, long time no "see". Dave, 60k dots out of a Camalot 2800 does not a "Dispenser Boy" make. :P I'd print them in a heartbeat if the proximity to radial leads didn't necessitate me placing radials first. Oh, wait, I'd have to

If that's the case, it's most likely the radio is bad. Again, I'm not clear, but it sounds like using the MD is the trigger to shut the player down: * Stop using the MD. * Fix the MD or some of the associated power supply regulation circuitry. For

Good points, John. Continuing to track on the voiding issue, why remove voids anyhow? * Voids are primarily process indicators. There is experimental evidence that voids retard crack propagation locally around the void on at least on a temporary bas

Guys I was wondering if anybody has some useful advice with regards to achieving 100% solder penetration on one pin of a through hole device which I believe is attached to a ground plane. All other pins on the through hole device are fine, Just this

GUYS HOW SAFE IS IT TO USE RMA FLUX WHICH IS DESIGNED FOR WAVE SOLDERING, TO USE FOR TOUCH-UP/REWORK ? CURRENTLY ALL OUR OPERATORS HAVE LITTLE RE-FILLABLE BOTTLES AND GO AND FILL THEM UP FROM THE FLUX CONTAINERS ( I'M NOT EVEN TOO SURE WHETHER OR NO

Being very new to SMT I won't assume I know what the problem is but.... I had lots of air pockets in solder joints, 95% of the boards. Everyone I spoke to thought it was a problem with my process but when one board was sent to our supplier they admi

Hi All, I am producing a lot of high cost PCBA where the pCB material is the `ROGER' material. Due to some of the high components and handling we get pad lifted issues sometimes and as of now are unable to do repairs on these. Please help if anybo

Thanks for your response Dave. I did look at the bare boards after wave solder and they seem to solder fine in that process. I do not see any soldermask bleed on bare boards. Regarding "thin" plating...I have had issues in the past when the board sup
