1.67 always on the sample boards measured. This is very fast and pretty good measurement for a paste dispense control. Boards do not stand out-side for long times. Inspect the height for critical components only, in the initial stages. Once your Cpk

Can someone point us in the right direction? We are trying to find a formula to determine the "cubic mils" of solder we end up with after reflow. (No components during the reflow) Some of the discussions we've had about it produced the thoughts bel

Yeah, those gosh darn disty parts...get you every time. lol Can we get just a little more info? Let's start with the basics... Stencil Thickness? Aperture Reduction? Leaded or Lead-Free? No-Clean or Water Soluble? How's your reflow? Have you prof

I have seen the U-shaped aperture on a customer site, being used with success. However, the problems with the stencil and the �loose� tabs where reportedly a reason to search for different aperture designs. Before this company could test their ideas

Please check what is the actual pitch size. I found some of the designer use 15.7 mil pitch and no accumulate ie 15.7, 15.7 and 15.8...... Also, I recommended the pad width should be 10 - 11 mil for 0.4mm pitch. You can open the 10 - 10.5 mil aper

Hi I completely agree with you. Also, the Dry Solder paste can be used in wireless repair operations such as the repair of smart phones, tablets, laptops and other handheld devices. The lead-free solder paste can be squeegeed through the apertures of

Hello, who is printing 0201 apertures or smaller and can provide information on stencil design, stencil thickness and type of solder paste?

Yes, there are adhesives designed just for stencil application. Usually plastic squeegee blades are recommended for best printing results. Plastic stencils are also available for this application. Both Alpha Metals and Loctite have articles on this s

To most of our boards I give 20-30% tolerance in both directions. From experience if you have big aperture on your stencil, the squeegee will scoop certain amount of paste from this aperture and you will see lower height. Depending on your board supp
