The US EPA has a Toxics Release Inventory (TRI) program. They may have some information on paste wastage estimation for leaded pastes.

I realize that I wrote wrong. Sry The stencil of 0,1mm of thickness is printing 45% more volume. I know this becouse the SPI is setup with the stencil gerbers and the messurements have a median of 145% of volume. what do you mean with excesive sold

Occasionally when circuit boards are manufactured, there may be issues with solder mask coverage. It is not uncommon to re-run back through this process to fix missing or thin areas. This can causes the traces to become higher which in turn raises th

Dear Steve, Thanks for your feedback in our experience add solder paste volume is better for the voids reduce of LED type components.

The thinner the stencil the bigger the variation in terms of percentage. Most probably it was experimentally established, rather than calculated.

Thanks, I do observed more solder paste terms of percentage in 0.06mm stencil than in 0.08mm stencil.

Hello, Has anyone dealt with the process of listing the substances on their electronic products due to REACH? I'm trying to find out if there is a way to globally calculate the area ratio of all the apertures on a solder paste stencil so I can calcu

Hi Researchmfg, If upload picture would be great to interpret this question, anyway,if bridge occur defect should be adjudge NG product,to avoide this issue,firstly,bridge is a PCB defect that happens when solder gets to an area it shouldn't be. You

I've been wondering if I was the only person thinking this. There are so many print parameters that are programmable now on new machines (squeegee pressure, height, speed, snap-off settings, cleaning intervals) that the process would (in my oh-so-hu

Didn't you hear? Fendelaz went out of business and sold the rights to the Magnaplancil to Amahlmahay. Sure, all the standard variables still affect the print quality (aka registration and volume) but if the machine controls everything but paste di
