Type in the part number at digikey.com parts search. Leave out the PEC and you will find three parts. One will direct you to the General Semiconductor site. This should help

If the shift is happening on different machines,it sounds to me like your pcba's cad data is incorrect or the board and/or fiducials are not consistent. Good Luck Bob

0603 component drift

Electronics Forum | Thu Nov 11 19:07:39 EST 1999 | Gary Kemp

We are having a continuing problem with 0603 chip capacitors not centering themselves on the pads during the reflow process, causing an open condition at one end. Does anyone know what can be done to alleviate this? Thanks much. Gary

Gary, We've experienced the same problem in the past, and found that moving the stencil apertures closer together solved the dilemma. This was a much easier solution than having to redesign the PWB. Leland

Please check the Chip Directory. Link to it is available from the bottom of the SMTnet home page, under Other Sites. Good luck, Cunli

Smt component shrinkage

Are they talking about size or qty ? Accountants sometimes refer to shrinkage when they are talking about inventory quantity discrepancies. Just asking, Don't know of a std that refers to this. Dave

Missing component benchmarking

If you are having problems with missing, misplaced RLC on your Fuji CP you should take a look at your board supports in the machine. Lack of or improper board support and bad feeders are the most common causes of misplaced RLC's.

As well as checking board supports you may want to check your nozzles and make sure there not stuck up in the windmill.
