We use a Hach digital titrator. You can buy a digital titrator kit, hydrochloric acid, phenolphthalein indicator powder pillows, turkey baseter (or some bulbus sucking device) and a couple small measuring cups. We do tests twice per shift (more is

Scott- I've used both methods, titration and refractometer. Both are simple to perform. Titration is a simple, high school science class type process. Follow the chemical mixes accurately and then compare the resulting color change of liquid to a cha

We use a blue Alpha 2110 saponifier in our H400 in-line water washer. Concentration of 4%. Works great but is EXPENSIVE. Brian

Naw, alcohol and solvents won't do dip. Hold-off on: * Destructive testing. [Athough this will convince you to move on to other things.] * Rework of the solder connections. [Although this will correct the problem.] Consider investigating your aque

The most effective cleaning of high solids RMA has been with a good saponifier (5-7%) [eg, Kyzen Aquanox, Lonox formulations, Envirosense Envirogold, etc ] in deionized water, 150F, with 2-3 DI water rinses. Dull solder connections when you do spot

Rick, Ultrasonics is a mechanical scrubbing action (cavitation) similar to any other scrubbing action, if you scrub long enough, you stand the chance of wearing away some of the surface material (shiny coating of a solder joint). The shiny coat on a

We are having issues with cleaning underneath leadless chip carriers due to their extreme low lying nature and I wondered if anyone else had any experience of this. Our process for years has been vapour degreasing with Triklone N, which works, but w
