Hello SMTnetters We have a unique application requiring cleaning of an aggressive OA flux. A vapor degreasing process or the immersion of the parts in boiling solvents has some process advantages over an ultrasonic aqueous process. These advantages

Resistivity Of Solvent Extract [ROSE] is a bulk ion contamination [BIC] test method. It should thought of as a process control tool used to assess ionic contaminants. Don't consider it an acceptable tool for establishing 'GO-NOGO' limits. The stan

Perhaps a little hard to find but is there anyone who uses a vapor phase process to solder populated card with BGAs. I am interested in the success rate of such a process. It is obvious that the throughput is reduce vs a convection oven but still thi

Manufacturers involved in critical product cleaning may be aware that the U.S. EPA may ban or highly restrict the sales and use of n-propyl bromide in manufacturing. The EPA is interested in the impact on small businesses including costs and performa

if is regardless of fluxes or population complexity my opinion is that inline aqueous with kysen liquid or other is the best because this liquid wash all type of flux and the aqueous wash all population complexity

SMTnet colleagues, I am looking for your opinions on the PCB/CCA cleaning process. Regardless of fluxes or population complexity I want your opinion on these three cleaning processes and what you consider to be the best for what and why. Thanks for
