Hi, all, does anyone know what mechanical test regime is used to qualify underfills for CSP use.

Are there SMT mechanical components like that could be used for orientating PCB-level optics on the board and do not require holes in the board? Their final position would solely depend on the reflow. A height of 1/8" would be sufficient. I was con

I'm considering using Delmat, or some equivalent material, as a stiffener for rather large pcb, but I don't know the material properties. Specifically I'm interested in: Young's Modulus, E Poisson Ratio, nu Density, rho Strength, Thanks, Jim

James: I believe Delmat is a proprietary product. Check with some of the solder fixture fabricators in the archives. Continuing, I would not select knowingly Delmat as a board stiffener. It's a composite material similar to oriented strand board

I am still learning the CSM84, but have gotten one board programmed and working. Now, I'm doing the next board, and need to use the mechanical alignment unit for a 22 x 22 mm TQFP. This chip is too large to clear the jaws on any head. Can the CSM h

Thanks! Well, the procedure in the book says to first calibrate the mech aligner with the beam sensor, but that exceeds the X travel. I guess you can just eyeball it off the nozzles and then use trial and error. While poking around on the machine

Your Head 1&2 have Chucks, is Head 3 a Chuckless Head? The Chuckless Head or Precision Head is the intended Head for use with the Centering Station only. Using Head 1 & 2 is not good as there is too much nozzle play. In your Machine Configuration is

Yes, I took the chuck off head 3, and made my own nozzle, which is working quite well. I can't set head 3 to vision, as this machine doesn't have the vision system. I set it to "IC" and that seems to work fine. I set mech alignment 1 and 2 to yes,
