Kerry, Why don't you purchase a decent stencil cleaning system that will not leave behind dry solder paste rather than purchasing a machine to tell you how dirty your stencils are? For less than the cost of a stencil inspection station, one can pur

I may have the oppurtunity to purchase a AAT Microjet machine with the Mach II drying capability. I like the theoretical cleaning/drying capability and power consumption advantages this machine could give us. The relative small footprint is also a

You may have answered your own question. CHEMISTRY, CHEMISTRY, CHEMISTRY depending on what type and whos product will work differently for each machine and Board geometry. I would ask Kyzen, Pertoferm, Zestron, and Aqueous Tech (all Chemistry manuf

Try to observe the board as it exits the wave, look for solder snapping as the leads finally exit the solder. The surface tension could be such that a "string" of solder stretches away from the wave until it finally breaks. Then, as the string reco

Most metal stencils today are cleaned with a water based cleaning solution. 3 choices are most typical: (1) Water only for water-soluble paste (2) Water + Organic for rosin and no-clean (low residues. This affords lower temperatures and is easier t

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

Hi Sarag, We share Sara's described experience with cleaning No-Clean/Low Residue flux residues. We can add that of the Low Residue residues, Indium SMQ92J is one of the more challenging flux residues to clean. That said, we have had repeated succ

There are several makes of stencil cleaning equipment. The previous post mentioned, Aqueous Tech (www.aqueoustech.com). Others of long standing high reputation are EMC Global (www.emcgti.com), Austin American Technology (www.aat-corp.com), and Tech

I don't know if it's legal, but I do know that other companies are doing the same thing. I have a couple of semi-auto printers that I actually sold my current company from my last company. Called 'em up a few months ago to order some parts and they w
