For a single board that takes 5 minutes to build on my machine, is it better to do it as a single board or a 4 up panalized board that will take 20 minutes to build? And why?

What is the maximum allowable thermal ramp rate for wave solder. We have a "short" machine used for selective soldering. To get the boards up to temp, we need to exceed our normal 2�C/sec. Are there any IPC documents governing this process? Anyon

a lot depends on the age and type of equipment you are using . Older equipment can have a lot of problems with smaller parts. If all is well with your feeders and machine you should expect something like 99.8 to 99.9 percent. some parts will be ident

JS: The issue is not how efficiently/effectively that you can run your placement machine, probably. The issue is how efficiently you can run that part of your assembly process that is the bottleneck. Other than improving quality, optimizing any pa

It would be helpful to have some additional info on your line and process. Lets make some assumptions... Consider: re-tooling costs for your fab supplier. Can your supplier hold the additional tollerences for a larger panel. Can your supplier fab

Hi David, In one of my previous jobs I worked as an AOI/AXI process engineer and we had a set target of 75% FPY. This means that 75% of the boards at IPC Class 3 standards would not have a single false call. This also means you would need to set y

Hello everybody!! I would like to know what kind of tool do you use to analize pick-up error rate at CP and IP fuji machines? Is it special kind of software or you use some customized solutions? Im thinking about writing some kind of database based

Hi, What is the expected reject rate for capacitors on a CP643 machine. I estimate that we are dumping around 1 in 20 on average. I have played around with lighting levels,vision types etc. Nozzles are in mint condition. Can anyone offer any advice
