I have a problem with solder getting into exposed gold pads. What is the best rework procedure for removing the solder and restoring the gold condition of the pad? At the moment, we are also covering the gold pad with kapton tape prior to solder

Dear sir, I have a problem to find the new chemical solution instead IPA(isopropyl alcohol) to eliminate contamination on the test pin socket board made from copper that plate with nickle and gold. And after the often testing IC process, the co

Quite simply, when the stencil is being auto cleaned, the operator can be doing another element of work. Also as mentioned, the stencil will be thoroughly cleaned as opposed to having any human errors leading to blocked or damaged stencils. The time

Dave is correct, a stencil cleaner is a good way to go. There is an article on our web site, by Dick Clouthier, that covers cleaning misprints with various types of stencil cleaners. Go to www.smartsonic.com and click on "Recommended Reading" to fi

Bill, Are you recommending the heat range of 95-100F (35-38C)to clean stencils with the Smart Sonic using the 440-RT SMT Detergent? The reason I am asking is were are looking at potentially the Model 2003 to clean our paste stencils and our adhesive

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

AOI technology is over-priced and inconsistent...lots of false errors. Your best bet is a paste height measuring device (3-D) Cyberscope makes one for 25-30 thousand. This process is really only necessary for high volume operations. As for you questi

Hmmmmm........I am thinking!!!!! Cleaning is the final process in our situation. After cleaning we have no need for the fiducials. Is the haze causing fiducial recognition problems? Ideally what you are looking for is a contrast between fiducial and

No clean residues can range in appearance from brownish gunk that looks like tree sap (because it is in some instances) to almost no residue at all. Is this product exposed to a wave soldering process or SMT? I would guess it's a wave process if th

Kerryn, It's the first time I hear someone who needs an automated inspection machine to check the cleanliness of stencils. Why not improve on the cleaning method itself. I use ultrasonic batch cleaner. It takes 3 minutes to clean a stencil, 2 minutes
