Based on your knowledge and experience, could you tell me about speed differences when placing a mix of SMD at mass production? We could consider packages like the small R & C chips, then SOD323, SOT-23, SOT-23-5, SOT23-6, SON6, QFN8, SOIC-8, SOIC-16

Thanks Alexei for your advice. I consider mainly high-volume production with tape/reel feeders for most components and tray for big ICs. My ultimate goal is a cost estimation of the production activities. So departing from a parts-list, I need to est

If you are developing a cost model for quotation/estimation purposes, we would recommend time studying a handful of existing jobs/set up's that you have, and averaging your actual CPM rate. Then determining your cost to operate from there. This wil

Hi, The issue is very complex and difficult to arbitrarily divide the types of components. From research we perform today together with our customers to design a work-at-SMT accurate as much as possible, I can summarize that vast time differences de

Thanks Rob for your meaningful advice. Instead of just a general average time per component, I think if we have 3 averages, 1 per "component group", we will gain significant accuracy in the cost model. For instance, a motherboard may have 2500+ R and

I've primarily used MyData equipment, personally, and, optically centered devices definitely take longer than mechanically centered parts on a MyData, owing to the construction of the machine. With a fixed upward looking camera, the head has to pick

If you're getting quoted .045 seconds per chip, or .9 seconds per IC, one of two things is happening. The most likely is the supplier has two machines in the line, one placing small parts quickly, and one placing large parts slowly. The part will run

Are you guys providing adequate board support during glue dispense and placement? I've had this same problem with 0603's that I was able to correct with adequate board support. Also, if you're using a Fuji glue machine, what are your temperature sett

Have you tried changing the Z speeds and/or wait times to help the 040 nozzle?

SMT part placement delay

dwl is right. You just have to spend some time to play with all the ones that causing the most delay. I would say the timing for X & Y axis try to set to max speed first (as long as not drops before placing). Then, slowly increase the Z speed until
