I too had to reduce by 50% because of floating (0.006"). But, most recommendations are for pads with via perforations. So if you are mounting to a flat pad, reduce even more.

Certainly, most often, the focus of pot analysis is directed at controlling impurities. Maintaining proper level of tin is important, also. When the portion of tin decreases: * Liquidous temperature increases. * Ability to wet decreases. * Solder c

Steve: Sure, but let's figure it out for you!!! ;-) Here�s some sample calculations. Your results may vary, void where prohibited, etc 20 PITCH: Pinched aperture volume: 0.010"X0.050"X0.005" = 2.5 uin^3 Zippered aperture volume: (0.015"X~0.5)

Guys Has anybody out there purchased or had any experience with the ECD Fluxometer. I've been shown a very quick demonsration but I'm still not 100% confident. For instance the mesh thickness is 0.006 mil and the yet the thickness of our boards are

Al, In general, I would agree with Justin, i.e. contact printing with a 0.007" stencil is great for 0603 - 1206 size components. However, we also place 0.025" pitch QFP components. We use a 0.006" laser cut stencil and I have found through trial an

| I have a mixed technology board ranging from 50 mil pitch devices to 20mil Qfp's to PBGA-352 at 1.27mm, and 6 Intel uBGA-48 at 30 mil pitch. With all these different package types i'm torn between using a 4 or 5mil thick stencil. The ball dia. is 1

Hi, I have a soldering problem with a header SMT straight single row of 8 pins. It's a samtec #TSM-108-03-T-SV-P (P&P). The first problem I have is an allignement one. I do not use alignement pin for now but I expect to use it. Concerning solder

Jack: Two concerns with column devices: 1 Coplaniarity of the device and the board. 2 Adequate solder that you mentioned, becuase the columns will not be reflowing and you need to cloatthem with solder. You didn't describe your aperture, but even

The Camalot Gemini II is capable of dots for 0402 chip. What would an Electrovert person know about that? With a 32gauge needle you can put down as small as 0.006" dia dot. For information about dots for 0402 chips, please contact Camalot application

If you failed math like I did. A 0.005 inch stencil would work fine for those parts. Most stencils are 0.004in for fine pitch 1005s 201s. 0.005in is probably the most common generic stencil. 0.006in generally is if you need extra solder for big parts
