It would help to run a carbon, anion, cation, mixed-bed configuration with pure DI as the final rinse. IF your incomming water is really bad you can run a RO unit to "prepare" the water for ion exchange. Do you run omega meter or ionograph testing

I've been looking for information on how, if at all, any of you treat water after a pcb batch wash. In particular, we have a Trident LD machine, using Zestron cleaning chemical. We have a carbon tank and two mixed bed media tanks as well as two 5 mic

Iman, How long after washing the boards do you process them? Are there any vias or Micro vias on any of the pads you see the blow holes on? A possible cause of a blow hole in a solder fillet or PCB is the escaping of Moisture under extreme temps. Th

we received assembled PCBs with spots that look like a bleach spots all over the PS and CS . The board house said that this is normal due to flux aqueous wash process. Can it cause problems (e.g. corrosion ) in the long run or cause issues when wor
