I am looking for outline tolerances of a flip chip with a pitch of .25mm. Bumps are made of 63/37 solder. Key tolerances are bump height and positional tolerance of the bumps. Can anyone HELP?

Wolfgang: "Our desire is to get what we design" ... Wanting to get what you ask for ... ummm sounds like a risky proposition!!! ;-) Two things: 1 Go to the Hadco site and get their "boiler-plate." Use it and some of the Earl Moon specs in the SMTn

The general guideline for most PCB manufacturers for PCB thickness tolerance is +/- 10%. Is this documented in an IPC spec? If so which one? Thanks Dave

I think that tolerance of pcb thickness is described in the �1-2-4 of IPC41-01 (Specification for Base Materials for Rigid and Multilayer Printed Boards Supercedes IPC-L-108, L-109, L-112, L-115, AM-361). Good reading,

Hi all, our problem we face is the mismatch of conductor width on the delivered PCB and the nominal width given by CAD-data. With CAD we are improving pads and conductors to match the specific needs for soldering and the board houses counteract our i

That�s what we consider to be practical if the 20% were the worst case we see but the reality looks different. By chance we get a -20%, sometimes worse, sometimes a "good" 10%, rarely does it hit the nominal value and never it�s a +%. In short: It lo

Are you looking for the pick and place error info?

No, guess I should have tried to explain it better. If I am trying to place a component at X-31.6 and Y52.8 What is the tolerance +/- that the machine will put it at that exact location. I know it's not going to place it at exactly that spot every

Can anyone provide me with the accuracy of placement for CM402, CM212, and CM602 machines?

May I ask where you were able to find this information? I have been unable to find much Panasonic information online. I would really like to find something that helped with their PT and PanaCIM systems.
