Yes, but even high force probes are not a cure-all. You still get flux build-up over time which can cause contact issues. The best way is to use a low residue flux in the wave to minimize what's left on the pcb post-wave.

Hi Guys, Have you tried using a standard dish washer for cleaning PCB's with BGA's. What detergent or cleaning chemicals did you used? I wonder if it will work to clean a WS Flux PCB using the dish washer then get it rinsed by an old aqueou cleaner

Hi Experts, I need help here, advice appreciated from all... Production is running a Lot of flex-circuit PCB, through the SMT line, with 0402 components. The flex-PCB is taped to FR4 support "pallets" when processing thru' the SMT P&P m/c. We use

I used to work with S15/F3, was a 10 years ago. 1. Test your machine controllers and station controllers. Load the last program with actuell command. 2. You can check what happening in the SiPlace, switch the monitor to MC, let see all bootup perfec

I guess I wasn't too specific. We currently use 1,1,1 for spot cleaning and minimal rework of PCBs. If there is a lot of rework on a PCB we will use water soluble flux and wash it. This may turn out to be our only alternative, but I hate washing a

Hi DaveF, To explain. The BGA that we have is from Motorola. The solder balls of these BGA's are Eutectic Solder and processed using a NC flux (as per info from supplier). So this means that the BGA pad and solder connections had NC flux process. W

If you were cleaning pallets, BTU air amplifiers or other tooling, I could provide some recomendations. However, we are not involved with the post solder cleaning of PCBs. Sorry. Regards, Bill Schreiber | I guess I wasn't too specific. We current

What I would look at is the chemicals being used in the facility where the complaints are. Flux/flux gel, IPA, cleaning agents, etc. Perhaps you should limit the usage to certain people only, who would be trained how to properly use these. Something
