Yes, I shamefully admit it, I HAVE put at least two cell phones into a bag of dry white rice to save them from having taken a swim in a toilet bowl and a swimming pool respectively.
While this may work for the occasional cell phone, it’s not the magic needed for water damaged industrial circuit boards. Take a look at the photos of this water-damaged Bosch circuit board that arrived at our repair center recently. Ugh! Looked like a goner at first sight.
But after taking a closer look and evaluating the board, we determined that it was probably repairable. We depopulated the affected area, cleaned, and reworked needed traces, replaced the damaged components, cleaned the contacts and plastic, reassembled and tested the board. Yes! It worked like a champ!
