Yano, imalookinat two vendor specification sheets that say your paste should sit around at "print temperature" for 1 to 6 hours before printing [er, words to that effect]. Werejallgit this 6 hours stuff from?

6 hours is just the figure I plugged from the sky. U-no-whak, this company used to follow 8 hours religiously in the past..scary huh!!! thanx..

Looking for feedback from people that used the Fuji CP6 to place 0201 parts. Is the CP642 reliable? I have been told that the Fuji CP642 cannot reliably place the 0201's and the CP643 must be used.

The CP-642 simply requires a camera upgrade for 0201 parts. This is the same camera as is used on the CP-643. You should then get identical results

We have been placing 0201 in our production using both CP642 and CP643 since last year. But it was necessary to upgraded a narrow view camera to recognize 0201 for CP642. Since then, the placement of 0201 is really reliable.

Hi all! I am looking at some precision SMT resistors, and am confused by what they mean by Temperature Coefficient (TCR) of whatever % ppm. Are they talking about from room temperature? Any info would be appreciated. Thanks!
