First, two points about hole / barrel fill are: * A filled hole is an excellent indicator of the optimum process and optimum quality PCB. * The study that showed that holes need not be filled was paid for by the US Army and performed by Lockheed in

Although water soluble (OA) flux is technically the easiest flux to remove, it is also the most damaging type of flux if not removed. A dishwasher lacks the pressure and nozzle design to produce the very small water particle size required for thorou
