Evaporator for batch washer...

Electronics Forum | Tue Jan 11 11:50:35 EST 2005 | Shean Dalton

Consider these three potential causes: 1) too much sludge - if the sludge builds up around or over the temperature sensor, then the sensor does not get an accurate reading. 2) too much chemistry in the evaporation solution - Check the temperature a

Thanks for the suggestions...The unit was just cleaned last week and all the sludge was removed so that shouldnt be it. As for the concentration, im not sure. The only water that has gone into the evap is the rinse water. So im not sure if that could

Leadfree Dross in Wave Solderpot

Electronics Forum | Fri Feb 25 18:13:17 EST 2005 | davef

Your leadfree dross should float, similar to your leaded dross. It's possible you're thinking about the process for removing excess copper from the solder pot. Following the same process, with: * Leaded solder, the copper floats. So, you scoop the

Kevin, Not sure about Florida but in Colorado we just transfer the wash solution to a drum and then dispose of it as haz.waste because of the lead. Currently costs about $200/55 gallon drum and we change the solution monthly. Another option would

Eyewash Solution solution

"Would you be able to use a piped water eye wash system? That way the water is always fresh." That's what you would think, but I've heard otherwise. If you don't flush them out regularly, the water will sit in the pipes and start coroding them. If

Vent Residue Cleaning

We use an evaporator, so that we only have a sludge of flux residue and solder metal to dispose of via the hazmat handling service. We also route stencil washer waste water into it. We use a 30 gallon drum and have it hauled off maybe twice a year,

Aqueous cleaner water disposal

MK, In most cases, if the machine is completely closed-looped (prewash, wash, prerinse, rinse, final rinse etc), then the water should not require changing. As with most inline cleaners, there should be a considerable amount of water loss in the cl

To lubricate feeders or not to lubricate feeders?

We recently purchased an old Fuji IP-I placement machine and have been testing 8x4 feeders for 0805 parts, etc. I have opened some of the non-working feeders to replace broken pieces and have noticed that some of the feeders are completely clean ins
