You're going in the direction of fab improvement, a great direction. But in another direction; If you're already in a carrier, how about using a skyhook of some sort to support the middle of the fab from the top side? In some cases you can put fine

Ramot, Without further explanation everyone here is just taking stabs at it..... Sounds normal, I'm game! Have you looked at board finish(HASL?)?? Measured paste height?? Are they always off in the same direction? If not, Handling?? What are the sp

Hi Ashok, you may look through the archive for "patches - Wolfgang Busko 09:57:37 11/12/1999" it�s exact the same subject. Do you have the newest IPC-standart Jeff is talking about in that thread ? What�s the reason for this measure, component-sho

Hi, If anyone can help me i would appreciate. I�m looking for a small circuit to measure the voltage of my car audio amplifiers. A small circuit with dual 7 segment display to show the voltage value. If anyone can help me please use my e-mail: br

Greg, Ioan seems to have the best advice. I would imagine, if you identify your zero point on the board, you would just measure from zero to zero after the necessary rotation has been completed. But, I am not familiar with the software used. Why doe

Do you know the wetting speed of the solder paste you are using? Ask your vendor for this measurement. I have observed this issue on several products using pastes with wetting speeds faster than 1 second. As stated previously, smaller packages are m

Robert, Have you checked for any form of contamination that might cause the solder not to adhere to the balls? From the pictures you have on the net it appears that you have too much solder on the pads. What thickness is your stencil? If it is to sp

I have experienced tombstone with one brand of 0603 capacitor. Swapping in another brand (actually two different brands to date) has stopped the tombstone. I have measured the parts (length, width and height). There does not appear to be any apprecia

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

Just a bullet! My results are, .005" stencil thickness should measure between .0055" - .006" if your pressure is correct, metal blades and snap-off is set up correctly. Do you have aperture reductions at the QFP locations "typicial industry standard
