We will be hand soldering a small number of PCBs per week (both through hole and SMT) using a water soluble flux. We will be using both standard leaded and lead free solder. The completed assemblies be hand washed in a sink using hot water. Do we

| I have been running a Stoelting Aquaeous machine and has been performing very well however. the maintanance dept cleaned using the descaler and now we are seeing boards with a removable thin film. We are going to to drain all the water and change a

A chemical change is needed to reduce VOC�s in our spray-in-air stencil cleaner. Items that are to be considered to effectively find a replacement chemical that works as well, or better than the current chemical include, but not limited to, the foll

WA Engineer, If you are able to change over to OA instead of RMA, you can clean effectively with DI water. (I know that some Military contracts specify RMA) Most systems are designed to filter the waste water of ionized contaminants before dumping t

We have lab sink in our SMT area that we use for washing off stencils and hand tools that are contaminated with solder paste. The sink has a float in it and when the water level reaches a certain point it pumps the main basin out through a filter th

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

Lazy operators empowered by management. Sounds like you may have some nepotism? Since it falls to you to clean up someone else’s mess I have an idea for you. I once worked for a company that had a large wash sink with a hand sprayer very similar to

Grant, No-Clean paste + IPA = White Residue! #1: Stop using IPA #2: Switch to either a solvent-based de-fluxing chemical or an aqueous-based de-fluxing chemical. If you are using an ultrasonic cleaner for your boards as stated, do not use sapon
