I'm not too experienced with this but what about an air-blast with an ionized air source such as an air knife above and below a conveyor to push most of the fluid off of the pcba then run through an oven just above vaporization temperature.

These micro ablation stations can be outfitted with air ionizers and you can use less electronegative materials like corn starch as the blast media. Laser ablation works on parylene and other coatings when on metal surfaces. BWET

in your example, wool clothing and prairie winter ionization makes sense. Smocks would be an improvement to contain the potential of static build up. If you go to dress codes, then you run the risk of having to provide uniforms or pay a laundry allow

We use a Charge Plate Monitor (CPM) tp monitor the balance of our ionizers, according to ANSI ESD STM3.1. Maybe you could use a CPM to assess the ionizing radiation in your plant. The more we think about it, we feel you could use a Geiger-Mueller (G

Dave is absolutely right! A question is there free standing DI water left on Parts after wash and rinse, if so this can definetly exacerbate the problem. You can try to remove excess DI water by using an IONIZER air source to blow off any water. S

Ladies and Gentlemen: Can anyone recommend a procedure for testing the efficacy of ionizing air guns (high voltage electric) on a routine basis in terms of a preventative maintenance? I know that you can get carried away with charge decay plate etc.

I am finding transparent fibres , specks or needle shaped threads inside my via holes. I am not sure these are fibre glass / epoxy or flux. I do not find many on bare board. The flux used is NC Low residue and this assy is Single sided . Presently

How does one keep a pcb safe from ESD when applying an aerosol conformal coating on a flat surface? Even if you had an ESD mat to place the pcb on it would quickly be coated. The only thing I can think of is an ionizer. Does not the aerosol create a

As long as you're convinced that your ionized air gun is not a static generator, it should work fine in dedusting your boards. As you say, covering your board racks while the boards are being stored is probably a better solution. If you google 'esd

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
