Hi, Currently my company is running entek coated boards. But whenever there is a misprint, we cannot wash the boards as it would diminish the coating. Is there anyway to clean the boards without removing the coating or is there a way to re-coat

I am looking into a pcb washer/cleaner for misprints etc. If you are using one, which would you recommend? We use no clean solder and will use lead free in the future. Thanks

We have been using Grid Loks on our MPM Accuflex machines and see an offset in the print every so often. Haven't been able to isolate the problem. How bad was the misprint and how was it related to the grid loks? Thanks

There is also an article in the March 2007 issue of U.S. Tech magazine that reviews ultrasonic cleaning technology for PCBs titled "Reducing the Cost of Misprinted PCBs". The information is also relevant to post reflowed PCBs. A PDF copy of the art
