Hello all, Can you tell me what standart is used for communication between machines in production line. I don't mean SMEMA. There is a standart for machine communication, they can communicate one with another. That is the way for example AOI says th

Try the IPC-254x CAMX standards (webstds.ipc.org, no www prefix!). They define a set of generic and process-specific XML messages for equipment to send out all sorts of process-related events. I know there are standardized messages for print, dispens

Hi Evtimov, Try to stay away from GEM or SECS/GEM. It's waaaayyyy to complicated and every vendor has there own interpretation of it when it comes to events and reports that are not commonplace in the semiconductor industry, which is where the GEM-s

Sorry for such a generic response, but you should consider SPI if you are not happy with the results of your printer. That is probably measured by defects at the AOI. SPI machines are quite expensive. I don't see the point of them when you can just b

SPI is especially useful when you start going to lower pitch/size components. Best use is inline to identify issues. It is a powerful tool in the right hands and a burden when operated by wrong people. I value it more than the AOI equipment.

Building on what Evtimov said, folks who are not familiar with SPI get freaked out when they first deploy it. You need to have an understanding of whats going on and how to adjust when you get "failures" I would advise that anyone who is g

HI, We currently have two SMT lines, one running leaded products and the other lead-free. There is a recommendation to combine the two to increase the line capacity. What do you think are the pros and cons, is there a risk in contamination ot the

I agree that if information is processed correctly up front in process down stream QA becomes less expensive ie AOI etc as AOI at end of lines is telling you you have made mistakes in up stream. I better to eliminate mistakes or have process to avoid

Hi Reese, unfortunetely our AOI isnot in line and yes we check first article for each board on the AOI.One of each five boards 1/5 we give to inspector to check and we X-ray if needed.

As the face of business changes through revolutionary factors, such as the increasing rate of outsourcing, manufacturers (especially EMS plants) will strive to fine tune their test strategies to ultimately improve and sustain product quality and to r
