I am looking for some equipment with a fairly undemanding capability. I would appreciate pointers to potential suppliers. Dispense size 0603 chips only, speed can be as low as 60 chips per minute. Only one type of component (ie one reel) is loaded.

Dave is right. There is no machine on the market which can handle a 1.5 m long "board". If you or someone else will have to tinker with a custom made machine, it will be less expensive to use a used machine ( I could be offering some used Siemens mac

Jeezuz... Darby is right. High Tech Squeegee blades are a crock of BS.Don't belive the hype. Its a big scam to rake in your dough. We use .008" thick spring steel stock from McMaster. There is only one thing:The blades must be dried off thoroughly af

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

Armin, The obvious disadvantages for an in-line printer is initial cost and flexibility for smaller shops that depnd on high mix, low volume batch builds from their printer to support multiple projects at the same time. The advantage is quality a
