Thank you for good answers. The Evest EM-780L machine that I linked to further up has a IPC-9850 at 25000 so if I get half I might be able to get the work done. How many people do you have working on the SMT line? Do you have all you're machines in

TP9 machines are good, but old machines. We ran a TP9 for many years. As the machine got older it required more and more maintenance and had more frequent small issues similar to what you are seeing. We only saw 1 of your 4 issues specifically whi

Thanks a lot. I`ve been doing a research for existing products as well and yes Teknek is quite helpful. Now I need to do some simulation analysis, collect some data and compare with manual operation in order to proof that this is a good and strong pr
