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

In addition to what frank said, I have also just placed the board on the work bench, but instead of trying to hold the board and stencil in place I would make a frame for the board using double sided tape, and after aligning I would tape the far edge

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

Dear J. Dumont, If the 4512's defoaming package is not active in the distillation process, then you may be dealing with foaming, which is exagerated at boiling point. The 4512's defoaming package may not be carried over in sufficient quantity from

Cross: IPC nor anyone else calls out recommended pressures for washers used to clean circuit boards. IPC and the other standards setting folk are in the business of defining the expected results or outputs of processes or acceptance criterion. They

Stencils on average should be a low cost to you, compared to the other equipment you are buying. A couple hundred bucks (U.S.) is all you should be paying. Making a stencil is harder than you would think. Set-up a visit with a local shop while n

Whoa dude - slow down- maybe great beer money but if you don't have good environmental and ESD controls in your shed, all your suds slush fund will evaporate in RMA's costs. A small pick and place (table top) would do. A manual screen printer would h

Thanks for the posts everybody. I thinks this is all or nothing, I mean set up my own business doing this stuff or forget it. I've been involved in SMT for about 5 years now and feel pretty confident with the process stuff. Just curious to know how

I do not know of any standard recommended values for impact pressure in cleaning equipment. They act more as a guide when examining the various choices manufacturers have made for the spray flow, nozzle pressure, nozzle spray angle and other factors.
