In regards to cleaning RMA solder paste from stencils; Right now we are cleaning the stencils by hand. I want to get away from this by going to an automatic cleaner. Any recommendations for ultrasonic stencil cleaning systems using 440-R SMT deterg

Ultrasonic I understand maybe the best at cleaning stencils, but we use a "pressure spray" it works very well and only takes appx. 12 minutes to wash & self dry. Alcohol is the cleaner, but there are several company's making detergents for cleaning

SmartSonic states that they will not sell their 440R chemistry unless it will be used with their machines. But to answer your question, the following manufacturers make ultrasonic stencil cleaners compatible with 440R and many other chemistries. Aq

Steve, When you say "CAD input", do you mean centroid data ( xy locations ) or generic cad info straight from the layout software. ( so far the machines I have been looking at use centroid) What are your rates of "false failures" and how do your o

Some AOI manufacturers require you to put in a GOLD PCB. Gold PCB is a perfectly manufactured board - Correct placements, correct polarity, no solder short, a "GOOD" PCB. With the vision limitations of some AOI equipment components that have variatio

The CAD data is the centroid data, x,y location. I developed an Excel macro in which we import the data as a text file and convert it to the CR Technology format. Rates for false failures varies, but is ~10 - 20%. The operators are given an oportuni
