Granite is a porous material and if anyone decided to clean this material you probably have an insulative barrier thus you would never have static dissipation. Spend $45.00 and put a mat over the granite or spend $80.00 and get an esd laminate materi

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

The propensity for flux residues to cause shorts can be increased in humid environments where water molecules hydrate the surfaces. At high frequencies, electrons travel on the surface of conductors/insulators, increasing the likelihood of shorts in

Hi Davef & Mikes, Thanks for the response. I am agree with both of your point. If the component bosy will be fall in Coductive or dissipative range, there are chances of shorting. Other thing in ESDS:2020 8.3 para is saying to keep away all the insul

With regards to PCB surface finish I would recommend Electroless Nickel Immersion Gold (ENIG) because of the long shelf life, tarnish resistance, RoHS-compliance, and easy soldering compared to other surface finishes. http://www.surfacemountprocess.

Hello, another SME is saying the solder resist cure level is suspect. I have had a industry SME make reference to this too. Adjusting the cure of the resist changes the surface energy
