| Hello | Is there anyone who can give me some information regarding yield from gluing 0603 | Is there any other problems that you might have had. | | We glue bottom side 0603's but have changed our pad spacing to accomodate tolerance requirements

most of the problems tend to be with TANT components and a few 0603 chips.

Is there an industry standard in calculating SMT process PPM level for benchmarking purpose ? What are the industry benchmark ppm number for some of the defects like solder short for 20-mil QFP, tomstone problem for 0603 components etc....

Never used U shapes for 0603 but have used them for MELF pkg. Never had a problem printing as long as area ratio is acceptable. So just out of curiosity, why U shape for 0603? Russ

skandaae: By "tilt" do you mean that one end of the 0603 has lifted from the board surface? If so, we call this "tombstone". In general, tombstoning is caused by an imbalance in temperature or forces on the component. * Convince yourself about the

Also most of Tantalum Caps are iron-magnetic material made, for sure is not this case but always wen we met problems like James met, we had always sot-23, light capacitors 0603 as you know some of them have Nikel barriel (also magnectic sensitive) an

Jim, Yes this does keep on coming up in the forum as JAX states. There is a pluther of information in the archives. I have had some problems with 0603's in the past. If it is possible, try using a 2% silver SN62 solder paste. This helped me in many s

Thanks for the reply. Like I just posted to the other replier, this is only a problem with 10MPF nozzles picking 0603 components off 8x4mm feeders. Feeders are all taught properly, and pick position is usually off by
