It really depends on the assemblies/components that need to be inspected and the available budget. 3D machines are much more reliable at detecting faults while not generating masses of false calls but of course they cost more than 2D machines. I ha

Ah...the joys of subjective analysis! At a glance, these pictures look fine to me. Other than the IC's, which you've indicated were masked, and, maybe R12 in the last picture and CC1384 in the first image, coating looks uniform and well distributed

Teradyne says, "How does one evaluate the competency of a particular AOI system? At the highest level, all potential customers must judge any viable AOI system using the following qualities: * Throughput must be able to match the line rate on the man

We are also looking for AOI machines, pre- and post-reflow. We already tried one machine from the UK (I don't remember the name, I perfer to forget we ever had it) and they told is it would do everything we wanted. Maybe so, but not well enough. It s

Hello, I have two of these for the last 3 years(MV-7xi). Buy the machine with the best camera they offer and with the telecentric lens - it gives great view and resolution. I had to replace the controller for conveyer open/close on both of them. I a

I am interested in discussing AOI. I am looking at introducing a system to a new SMT line. I am very interested in hearing from someone with MVP, MVT, Kestra, and CRTechnologies. The combo of x-ray and 2D inspecion that CRTechnologies offers is very

Normally inspector is operating the verification station - such as checking the components found by AOI, feedback to the system about real defects and false calls, scanning barcode to find certain board, load data for the recipe and so on... Line ope

With any AOI machine, it will only be successful if your programmer is interested in getting it to run well. It is not rocket science, but if you want low false calls you need to invest time and energy into programming, especially if you have a high

Thanks for the spare change. Questions are good and I did miss one item. Process has 100% solder paste inspection with a 3D inspection machine that has very few false calls or accepts. Ramp to peak is less than 1.5C/sec. Profile looks good, solder

HI, i work for an EMS company and i got a few remarks on the solder mask question. In the manufacturing of PCBs there should be no difference if they use other color solder mask, but in the production of electronic assembly it could make a difference
