physically lift board of after fluxing to visually see what is covered, or using thermal fax paper to get to see coverage works well. PROPER low residue or no residue fluxes leave benign insulating residue behind not corrosive.

Current limiting resistor: Personel safety Electrical equipment on the ESD matt: We need more information. Is the equipment ground of the equipment in contact with the matt? Or are the insulating pads on the bottom of the equipment in contact with t

The adhesive should be a dielectric (insulator) by design, if not it could possibly short across leads of the very parts it's intended to secure. It normally isn't a concern - what is the surface resistance of your soldermask, bodies of ICs, ...etc.

Why reinvent the wheel, Bart? You can buy a thermal barrier from one of the logger manufacturers (M.O.L.E., KIC, DataPAQ, etc). They come in varying sizes and temperature ratings. Maybe you can find one that suits your unit. Good luck.

Those are IDC (Insulation displacement connector) you can make them yourselves. you can get the stuff from Digi-key, Newark,Allied, Mouser. If I left someone out sorry.

Seems really excessive. I am not familiar with that particular oven, but I would check to see that the fans are not seeing excess heat during use. Is there any ducting around the fans that might have leaky joints? Is there insulation around the fan

Hi Hege, there is insulation, which when you look at looks pretty stable.I suspect that there is more heat transfer through the shaft from the propeller to the motor. However when I touch the motor it is not really hot, so I am confused what really

I have previously done a masking fixture through Pentagon, but was unsuccessful I think more due to the design of the board. Does anyone else have experience with other vendors that I could try out? I have seen InsulFAB and Ascentec as well. Thanks.

In ESD-head parlance, chairs are "Process Required Insulators." Checking PRMs once every 3 months is a reasonable starting point. Review that period after a year.
