Smaller mesh does not mean better release. The flux component will affect release much more. Paste manuf. Like to tell you how good they are but it doesn't alwyways work the way they say. -----Original Message----- From: Jason Gregory [mailto:[log in to unmask]] Sent: Tuesday, October 26, 2004 2:45 PM To: [log in to unmask] Subject: ****SPAM**** [TN] Question about 2% Ag and stencil release Has anybody had any experience or seen/written studies involving 2% Ag release from stencil apertures? We have a stencil, parts are small resnets, about 15 mil pitch on a .006" thick stencil. Tried 2% silver paste (for tombstoning of other parts) with type 5 powder and had major release problems. We kept the same parameters on the screen printer (for reference/control purposes) and swapped in our "normal" 63/37 Type 3 powder and release issues "virtually" went away. Not all the way, but for the most part. I thought smaller mesh should have meant better release. Solder gurus ------- enlighten me!
