Hi All. Need some immidiate help. I need to know any / all basic info regarding Teflon PCBs. Any special requirements for assembly on SMT and thru-hole lines, like profiles, placemnt , wave etc. Will there be some basic / big differences in comparis

A small assembler with a pair of tweezers maybe? just kidding. There is some table top placement equipment available but I can't remember who or what. Try a Google search for SMT placemnt

Hi I have a question about fiducial mark. Can anyone explain me how it is work?. Do you have to during programming set exactly center of the mark? or approximate point the mark and the machine during placemnt will correct it. In some P&P i have met

I'm trying to develop a process for a small assembly consisting of two mirror image PBGA connectors, I've built the first prototype, but I ran into different problems: 1. The SMT connector was shifting during placemnt, and I knew one issue i have to

We have auto-correct funtion on our Panasonic Create CM-301 placement machines but have never turned it on because of a perceived loss of placement time when the camera verifies placement. We look at the first article and correct placemnt if needed.

Some machines may require that the two locals be used to calculate a center point where some (probably most) just use them as a second positional identifier. The fiducials are programmed as just XY and just prior to placement the machine will read th

Q1: You say that 0.008" of "slop" is un-doable; hence, the reasons for our failures. Any basis for that statement? A1: We're not even considering the accuracy of your placement machine. We base our comments on the gap between the hole and the connec
