We intend to promote the new PCB cleaning process with acqueous chemistry , but we face with an important demand : Do we have to dry the pcb after ? Wich is the treshold humidity content to avoid any risk for FR4 material ? Regards Pascal

Pascal, Hopefully, the system that you invest in will have a programmable drying cycle as one of its features. As far as humidity content is concerned, I am sure that some more learned colleagues may be able to help you. Although, I believe some p

Pascal: Responding to your questions: 1 Do we have to dry the PCB after cleaning (sic)? Generally, nothing says you have dry the PCB after aqueous cleaning. Along this line, I received several thoughtful responses when I posted a similar thread.

We are interested in hooking up a batch acqueous cleaning system in CHICAGOLAND area (for cleaning RMA flux). Can somebody recommend an EPA contact? What type of regulatory requiremetns would there be? What agency should we seek out before we instal

We have a customer whom we have built boards for. They want a "cleaner no clean look". The process uses a no clean Kester 256 SN63 solder paste. After reflow the "residue" noted by the client is too much. We have tried a few things. We are a small

First, you must determine a few things: 1. What specific de-fluxing chemical are you going to use? Basic required determinations include the chemical�s pH, is it a VOC (if so, what is its VOC content), what concentration is the chemical used in (1
