The way to determine correct pressure (in my experience) is to start out at what you would consider to be a low sq. pressure setting. You are looking for it to leave a slight film of paste on the stencil. Start increasing pressure in small incremen

Hello Sanjay! The cheap deal I use that Earl spoke of is called a SMarT Measure. It's a depth measuring microscope that uses the same principle of measuring optical focus that the units from Vision Engineering do ( if you've ever looked at any

It sounds like a bit too much solder on the PWB, caused by too large a pad for the lead it will contain. In that case solder reduction is the way to move forward. What are the options there? 1. New stencil or stencils - (not desirable) 2. Increas

Folk's, I've been running with the datapaq system for about 5 years now. I have been using it on both reflow and on wave, the only issue I've ever found is that you cannot predict settings for wave, but then you can't do that on Kic and I don't thin

Hi Evtimov 'hege gave you a plausible explanation for what's going on with solder running-up the lead of your components: TOO MUCH METAL!!! I've got different one. This explanation goes along the way that you're thinking, but just opposite. The rea

Hi Guys, I've compared stencil printing adhesive versus acquiring a dispensing equipment. Had breakdown all the costs against each other. It end up that Stencil Printing Adhesive is more costly than equipment dispensing machine in the long term (5 y

OK, I'll bite. How you can set a stencil down on a printed board and run a squeegee across it (even if it's a proflow head, it's still a squeegee, right?) without disturbing the printed paste?
