Mike - I'm not in the EMS business, but I suspect most of them are very reluctant to reveal much about their quoting process. You might want to try some of the third-party data suppliers like Ceeris (www.ceeris.com), and you can also check the C

Good morning. I am currently in the process of validating our quoting process in comparison to what our colleagues are doing. If anyone could let me know what is the average cost per component for their smt operations I would really appreciate it.

First evaluate yoru Reflow Oven: does it have independant temp control for Top and Bottom Heaters? This is a MUST.

Bob Willis and Phil Zarrow have published recommendations in this area. * Search the fine SMTnet Archives for references to their findings. * Read posted papers on the topic on their sites.

Here is a formula that may help. C/P C= Component's weight in grams P= Total pad area in Sq. in. Must be less than or equal to 30 Parts larger than a 68 pin PLCC should use an adhesive. Hope this helps.

surface tension is what holds the parts on when solder is flowing I would add some glue under the parts that I placed on the frist side the glue will add more surface tension. this is if you have a glue dispencer in your line already.
