I'd wash them first then AOI. Especially you use the same AOI for WS and no-clean. You certainly will not want any WS flux left inside teh AOI then use the AOI for a NC PCB...

Does anyone know where I can find something in writting on the proper ways to clean a mis-printed board using no-clean solder paste? If not, can any of you tell me what the best way is? Currently, we are running mis-printed boards though the Aqueou

You already have some good answers. A chemical isolation zone for RMA is a good idea. If you are looking for new see the two references you have and Austin America. If you are looking for used, see us at http://www.ietechnology.net. We presently

The big problem we saw was the appearance of the solder joint after the water wash process. We saw the joints turn white through the absorption of moisture. Looked real bad but still functioned. I would stick with using only one of the processes a
