Russell Claybrook, one of the cleaning experts from MicroCare Corp., addressed a very specific issue involving PCB reliability at the Texas Cleaning and Reliability Workshops. In particular, Mr. Claybrook focused on the need for process control in benchtop cleaning and automated cleaning of fluxes on PCBs.
Claybrook stated that process control remains a major deficiency in the cleaning of PCBs, wether it be on the benchtop or in an automated cleaning system. With more than 30 years of experience working in the industry, Claybrook has expertise in both PCB assembly and rework. He presented methods and tools for creating an effective ‘Process Control Program’ for PCB cleaning.
“Bench top cleaning still is performed with the same methods companies used 40 or 50 years ago,” he explained. “It’s ironic that manufacturers devote enormous amounts of energy and capital into process control at printing, placement and reflow, only to abandon that discipline at the bench — the final assembly area most circuit boards pass through before shipping to end users.”
