No doubt. Now a days component mfgers have just changed their plating for no lead, but dare not post the max temps for their product which are at the edge of destruction. Kinda like the surface mount batteries that can't take the reflow temps.

Depends what is adjacent to the step. 1206 chips could reside closer than say a 16 mil fine pitch. Larger apertures are more forgiving to height variations than small apertures.

Kenny, Why are you using a step? The components you list could be done with the 7 mil stencil. I would use 6 mil myself but I assume you may need the 7 mil for other components you do not list. Jerry

Now that Zestron has lost all of their American employees, their writing sure has suffered. http://www.emsnow.com/npps/story.cfm?id=17477

What is the IPC norm wich drives the IPC stencil aperture design? The contest is: a stencil for the deposition of solder pastes on bare boards Thanks

The key driver to aperture design is to assure a fillet of the proper height for the component temination and the reliability of the end-product customer use environment.

I may be wrong here, but it sure looks like used equipment brokers have been spamming E-mails to myself and other members of this site from our contact info that is available here. Anybody else seeing this ?

Actually we have been getting spam to e-mails listed on our web site. The e-mail address I listed here is different so I can monitor this type of activity and I have not gotten any spam from it. Jerry
