Removing carbon finish from pcbs

Electronics Forum | Thu Jun 08 11:05:27 EDT 2017 | davef

By the way that you stated your question, I assume that you want to do something different with the carbon inked pads. If that's incorrect, instead of removing your carbon ink, considering printing an insulating layer over the ink.

Ground straps and dress shoes

Electronics Forum | Thu Dec 28 14:50:56 EST 2017 | stephendo

Leather is not very insulative. AFAIK a lot of good quality dress shoes are naturally ESD safe. (or maybe test too low.) Check the dress shoes with a tester. And I'm guessing that stapling the straps is out of the question.

How to identify any Vibration Source in Reflow Oven

A recording accelerometer is about the only thing I can think of. Unless you can find an insulative container (like for a profiler) you'd just have to run it through a cold oven.

Curious PCB technology

I have to ask this because "Material is applied over bare aluminum" doesn't make sense to me. Is that some kind of electrically insulative black anodization on the board surface? Because if it's just bare aluminum, how is the entire circuit not sho

Steve, I am sorry for misinforming. Indeed, there is a sort of insulator over aluminum that looks like powder paint. No hesitation the circuit would be completely shorted otherwise. Regards, Pavel

| I need an evaluation process to prove to a customer that our no-clean process does not leave excessive residue? Any ideas? Justin's right - you need to find out why there is hesitation about residue. Right now I make a board that has contacts for

Flex Circuits reflowing

Hi Chris, I had worked for a flex circuit house for 10 years. You should be able to follow your solder paste guidelines for times and temps. You may want to consider pre-baking the flex if it is made with Kapton. Kapton is Hygroscopic and will delam

Custom Super M.O.L.E. Thermal Protective Enclosure ?

I have done this for the Datapaq and it worked well. The SlimKic uses a yellow thermal blanket material. It is called Pyropel. You can get it at McMasterCarr. I think McMasterCarr calls it polyimid foam insulation part number 93015K64 of 3/16 thi
