I would like to know if there is an International standard for BGA and QFP polarity in trays for pick and place. How are these components placed on trays and is there a polarity of the tray itself? Please feel free to send me an email or reply on t

Polarity in tape and reel is usually always on the bottom left side. And that is correct for the trays, they have a corner taken out where the polarity goes. Hope that helps........

Hi All, The method that I use when training operators is.. a visual aid that shows the operators what way the trays are placed into the machine and the polarity of the component and also the component change logs. The matrix trays that I have delt w

Hello, are you useing any Through hole AOI in your conventional Hand Assembly and what Typ is it pre- oder post-solder? And what errors are you ecpecting to detect? -missing component -component Offset -polarity Check -or??? Is there Any Manufactu

Agilent has a great article on determining whether automated optical inspection (AOI) or automated x-ray inspection (AXI) is right for you. It's a PDF file that can found here: http://www.ate.agilent.com/EMT/LIBRARY/X-RAY/DOCS/59883661en.pdf To sum

When using AOI for through hole you can expect to be able to detect, depending upon whether inspecting from the solder side or the destination side: Polarity (if applies) Value (if marked) Presence (should be there) Non-Presence (should NOT be there)

I have tried the IPC calculator and they do not have this type of component registered. When trying to select 'other' on menu, no connection can be made. The polarity if the QFP has not been decided yet (pre-PCB design) the pitch size of the componen

Does anyone know how to generate a Part Data for a QFP with bumper for a IPIII machine on MCS software? I realy have a bad time with this issue,somehow the vision type is not detected...
