PROPER GROUNDING OF THE "OBJECT" PCBA BOARD: You cannot ground an insulator. Insulators accumulate a charge, but the charge must be neutralized, usually by ionization. We only use ionizers at tape stations and bins where travelers and other paper

Some people put spark gaps on the PCB it a trace that comes to a point that's exposed from the circuit you are trying to protect to a trace that comes to a point from the ground trace. The 2 points are about .005 inches apart. When the charge hits th

In case if static charge was built up on the surface of the component reel, it is possible remove static charge?

Offcourse, RH is between 47-50%. The cause of problem is that the one of the embossed carrier reels/package materials coming from supplier static charged. Material now is like insulating, not dissipative or conductive. Example: https://drive.google.

I'd don't believe that the reels need to be ESD protective material. The carrier and cover tape have resistivity and materials specifications. Start with EIA-481. In past threads on SMTnet, we have discussed problems in picking components that wer

Does anyone knows if usage of plastic trash bags inside trash bins can effect static charge accumulation. And is it preferable not to use such bags to minimize charge. Thank you Vic

George: So, how do keep your stencils "made from plastic and have underside routing to allow relief for through hole components" from building-up static charge during print cycles and handling and then discharging through and damaging the PTH compon

How are you going to ground the metal sheets? You certainly don't want to leave these hard grounded; you need to dissipate any static charge over time.

Potential causes are: * Static charge [get a deionizing fan] * Adhesive on the inside of the cover tape [fix your supplier]

Agree with Davef. Smaller the chip, more the static charge. I used to see this even with normal chips. Get an ionizer blow. It should solve your problem. May be switch to antistatic tape if affordable.Regards. GV
