I know it is not what you want to hear, but first and foremost, you must consult your local regulating agencies and here is why: Solder paste contains heavy metals. We are all familiar with the problems associated with lead, but lead free solder pas

We have been having an ongoing problems with radial electrolytic capacitors (thru hole)for some time. 1. When we wash them in our inline cleaners the sleeving shrinks up from the PCB leaving the 'can' exposed. Some designs have traces on the surf

James, Most rental DI systems are as follows: Option #1: 2 mixed bed resin tanks: In this case, a 1 M-Ohm light should be installed on the output of tank #1, before tank #2. When the 1 M-Ohm light indicates that the output of the #1 tank is below

We have a name brand aqueous batch cleaner that uses a chemical and DI water to clean ROL0 flux from our PCBs. It does ok most of the time for SMT boards and we want to include through hole assemblies as well which should be a better cleaning process

Thanks for your reply. I 've tried to clarify and answer your questions. The water soluble paste used is WS3060, type 4. The boards are sent through a inline di cleaner after reflow. There is a hot Di waterwash, rinse and then hot air to dry the wa

On the printer alcohol always worked way better than water. If you talk about after job is done, most stencil cleaners work with some solution/saponifier and DI water.
