Does anyone have any articles about performing the green stick test for IC leads? If there are no printed articles then perhaps I can get a good description from you on the proper usage of one. I would like to know from your experiences any pros and

In-Circuit Test is the best method for ensuring solder joint connections. It is a much more reliable than AOI. An ICT machine can ensure solder connections are made for array package devices such as BGA, PGA, etc... AOI is best for component I.D.- is

In my experience AOI's are good for checking machine setup I.E. first piece inspection. After that the only things they will typically catch are wrong parts, reversed parts, missing parts, and tombstones. I would however suggest getting an AOI with a

Hello everyone, I am currently looking for a test handler for memory module applications. The one I have seen stacks the modules on top of each other. I am worried that this contact may damage the capacitors on the modules. Does anyone have any exper

Certain ICs cannot be place by our pick and place machines and therefore operators place them by hand. Has anyone seen some type of dispensing material handler that would ensure we don't bend the leads of this fragile devices? I'm envisioning some so
