Hi Mark, Thanks for your responce! The stencil thickness and especially the reduction of 45% are not recommend by LT, did you came to this combination experimentally? We never have the illusion to produce voiding free, but now its around the accepta

Jigo, We have never had a need to do internal testing on solder paste, and your paste supplier should be able to tell you what the correct operating temperature range is. All of the big names in solder paste have tight quality control and I suspect t

That's my main concern, the patchy/splotchy appearance doesn't look as pretty, especially under a microscope. When it was mentioned that my oven may be too hot in the ramp-to-faux-soak it was the first thing I tried adjusting. As far as our blade pre

Hi Rob, Thanks for the LED paper. I like the void area equations but I am puzzled, the paper did not say if the solder was a solder paste that would generate a lot of voids, or a fluxless preform or sinter material. The measured voiding level

Currently trying to get away from using stencil printing. Looking for information on Micro-Dispensing and dot size using a Vermes MDV-3200A micro jet dispenser. I am using a Indium led free solder that has size 6 balls. With a 100 micron dispense hea

Spray cleaners are poor alternatives to todays ultrasonic stencil cleaners. Ultrasonics are the way to go and you can use rather benign water based chemistries to get the job done. As for screening adhesives and cleaning glue residue with spray wands

Hi Yannick. This is an issue that we are just recently getting into but here is some ifo that I have gathered so far. I have seen/ used 2 different rework machines. The one we have bought is a 'PACE TF2000' which was at the lower cost end of the mar
