| I am running composite fixtures on my wave solder machine and after about 500 passes each (1 month)they are showing serious signs of wear in that the composite surface is bubbling up and glass fibers are also starting to show. | The problem here

Sounds 'on the money'. By gear up, I assume you use respirators. Wipe up any dust deposited on surfaces and dispose of the wipes as lead waste. Keep the cover firmly on the dross can when not in use. You've got it covered (pardon the pun). Do yo

Hi, I used to run a clean room, and it's right, most of the dust is created internally. You will need to add some HEPA filtering to the area, and an air handling unit that can control temp and humidity as well to get correct environmental control.

Use a router with fiducial correction? in reality if you are putting a PCB in a plastic enclosure then the injection moulding is going to have far greater tolerances than a laser or router depanelised PCB is. Also, if our laser markers are anything

It is often said to avoid card board material in SMT area due to dust, i.e. card board boxes etc. are dust generators. Except from house keeping, cosmetic and optical issues, what other concerns are there in SMT/Electronics manufacturing? Solder join

Hi all, we will be moving our pcb production to a different (newer) part of the plant this summer in an effort to reduce dust and better control the temp/humidity. What can I install to keep the dust down? Are there air exchangers/filters for a room

It's dust contamination. Most of the boards have loose dry dust on them but a few have what looks like a dried slurry. Either way I'm not impressed. This is the second batch, the first one had obvious *visible* shorts on boards that were alledgedly
