I'm trying to find a solution that will clean our PCBAs that will meet the following criteria:
1. Low cost 2. Enable us to clean 25 - 100 PCBAs per day 3. Leave boards clean, including residue removal 4. Preferably environmental friendly 5. should be able to handle PCBs ~12" max edge width
We use RMA flux right now (SN63PB37, rosin core).
We've tried cleaning by hand with Vigon EFM and / or RC101. EFM left lots of thin residue on the assembly. RC101 couldn't clean off thick flux deposits. I tried a dual process and the results were better, but I had to spend way to much time cleaning and often had to cycle it more than once.
I'm envisioning an inexpensive aqueous batch cleaner - we do have easy access to DI water.
Can anyone help with any suggestions?
Thanks in advance.
