I got an inquiry from one of our electronics labs with regards to their soldering processes. They use eutectic (63% Sn, 37% Pb) solder. For liquid flux they are currently using Kester 186, which is an old-school, full rosin (RMA and ROL1) flux that c

Hi, We are planning to use RMA flux based Solder Paste for our line. We are currently using a No-Clean Solder Paste. Can I use an aqueous cleaner to clean my board with the above paste ? How will I clean the board ? What are the advantages and disad
