We are trying to establish requirements and process controls for completed, cleaned SMT assemblies. We have problems with our high impedance circuits (100 meg ohms) being affected by residue. Some boards require additional cleaning cycles to remove

Mike Conrad's "matter of full disclosure" is not quite complete. He fails to mention that he only makes spray-in-air board cleaners and only ultrasonic stencil cleaners. He does not make ultrasonic board cleaners. So, he apparently he is "grinding

We have an application where an assembly has to be residue (flux) free except for 2 SMT non washable parts. Currently those parts are post wash hand adds but the product volume is exploding. We want to run those parts in SMT, mask them using an aut

Bill S. is correct on the positive effects of the Smartsonic 440-R SMT detergent. We have been using this in conjunction with a Smartsonic 4200-2D ultrasonic washer that is equipped with a tank heater set at 100'F. Our suggested process window to p

I am looking for a little enlightenment with an issue that we have been seeing. We have SMT assemblies with poor solderability on TSOP and mini-QFP type devices. The solder appears to have incomplete reflow and/or grainyness to the joints. Everything
