You have a rather old machine that you are running....now realizing this you need to check some things. 1. Clean the scales in the x and y direction. On some of the encoders there is an led to see if its reading correctly....Usually it turns green b

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

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

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

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

Thank you for your response! I was actually the guy who emailed you a few days back regarding the blank.jpg error message in PCBsynergy. I would really like to try it, but that error is preventing me. I don't know how to initiate communication. If

We're an OEM Tier 1 Automotive Supplier, (Yes, one still exists in the US), with two SMT Lines and we splice all day, every day. First, let me say, I 100% agree with Rob's comments above. Technique is everything. We use ASM SiPlace, (formerly Sieme

I'm looking for a typical SMT placement defect rate from others in the field so I can judge whether or not we are in an acceptable range. If I give you a board with 200 components (0603, 0805, SOICs, 20mil MSOPs, tantalums, DPAKs and a few 20mil fin

Hi, If you can not rely on your programmer and the tools he uses then "double checking" can save you only materials but in time you really do not save often extend meaning. There are things you can identify before the stove, but if you use tools li

Our company has a process standard that requires a double person check at the beginning of every run (size of run is irrelevent, whether 20 panels or 500 panels). Every changeover that occurs a first piece inspection is made before reflow. If all is
