It sounds like you are getting CPH numbers without taking into acount Machine utilization and efficiency. By doing that you can overlook what the real problems are. First find your utilization numbers... available machine run time with respect to th

I agree totaly and would like to thank Mr. Bliss for his reply. I would also suggest that anyone who is serious about SMT manufacturing, read the "White Pages" on the Bliss Tech. site. The concepts are very basic but still good. Thanks to all of you

I'm looking for other performance metrics equations as alternatives to OEE. Machine utilization and efficiency are what I am concentrating on. Thanks

I am looking for some suitable SMT production performance metrics for a high mix, low volume setup. Currently we use CPH and Machine Utilization. However, in the process of catering to the HMLV setup, we have more changeovers and so the utilization a

If you are comparing the machine utilization to the manufacturers best speed generally it is less than 20%. i.e. Fuji CP6 max manufacturers speed = 40000 placements per hour. When you add in downtime, breaks, maint, set-up, feeder replenishment etc

If you are talking about failure analysis and machine utilization information try looking at CIMCIS. They have a wide variety of products that can help. You might not even need their services, most SMT equipment has software packages that will allre

I'm sure that Ken has commercial goals, but after reading his whitepaper I'm sure that many manufacturers could benefit from it. It's just to easy for a management to save costs on feeders, without really having an idea of how it affects the amount

Brian, I believe that someone has given you incorrect info. Both of these vision types ignore protruding nozzles during vision processing. I am currently running 1608 components with a 1.0mm nozzle on a CP-643E series machine utilizing vision type

Cant put a finger on it being an encoder that was just a single possibility. You can always hook up a scope to the encoder and see if they are working appropriately. I would look through the machine's utilities and see if there is some debug or more

Now you are going too deep. Purchasing should have nothing to do with your placement cost. Reducing part numbers too. These are separate processes and should be evaluated separately. You have: 1. Machine time and cost -utilities -maintenance -consu
