I am looking for an industry standard �stock� note to place on our printed circuit board assembly drawings that will capture a level of cleanliness for an IPC-A-610 class 2 board assembly. I�m looking for some quantitative spec for cleanliness that w

By definition, no clean solder can be not-cleaned. The solder/flux are formulated to result in low ionic-contamination, hence, no cleaning. I have, however, always had at least one customer that requests their no-clean solder get cleaned. No-clean

We have an Ionic Contamination Testing system but short of having a monitoring record for the chemical concentration. What we have is a monthly maintenance check of the concentration and annual check and calibration of the chemicals. We seldom use th

Most ionic contamination testers prompt the operator for the current concentration at the start of each cycle. The normal concentration is 25% DI Water and 75% IPA. Although most machines ask for the current concentration, concentration adjustments

The most common method is a R.O.S.E tester. They have been around for 30 years and are an industry standard for ionic contamination (flux and other residues) testing. Manufacturers include: Zero Ion www.aqueoustech.com Omegameter / Ionagraph http:/

| We understand that testing for ionic contamination and surface insulation resistance measure different properties. We assemble printed circuit boards for other companies. We will not get combs on 90% of the boards that we assemble. | We have no c

Definitly evaluate the TD washer smt 324 / 318. I have two units and they have been fantastic from a maintenance point of view. Small, quiet and easy to maintain. I am in the middle of cleaning capability and ionic contamination testing as we spe

Rick, Ultrasonics can damage some components that react to the mechanical action of the ultrasonics inside the device. Some component mfr data sheets will comment on ultrasonics. Better safe than sorry. Dean makes a good point if you can change so
