The best way that I have found to calculate CPk for placement machines is to buy the kit that is usually provided by the manufacturer of machine. It usually consists of a glass plate and glass components that are scaled. You simply program the mach

Charley, I have worked on QP242's for 1 and 1/2 years. It is a very reliable machine but like all machines, PM's are very important. When I first got to NOKIA I wasn't familiar with the QP's. Mostly IP3's, IP2's. We are placing 16 mil pitch parts

I am currently sourcing equipment to mount CSP devices. I have looked at the GSM Flexjet & also the Siemens 80 F series. However these machines only look for ball presence not ball deformation. Panasonic are the only ones who have a 3-D camera capabl

We are looking into a SRS machine, and one question keeps coming up, "If we pull out all the solder, will the recycling company refuse to purchase the remaining dross?" Anyone who out there that uses a SRS machine(Solder Recovery System) I would app
