I am looking for public papers or articles on intermetallic formation as a function of reflow profile. Most solder paste vendors specify peak temperature and time above liquidus, but I am particularly interested in what happens to intermetallic grow

It won't help your operation of a pick and place machine, but if you are just beginning to train your Operators, an excellent beginners' reference for SMT parts and package recognition can be found at TopLine Dummy Components' website, http://www.top

Can you tell me how to distinguish between them? I recently bought a second GSM2. With it I've got two FlexJet heads (dismounted). The serial number of both heads starts with FJ7P, so I assume they are of FJ7 type? The issue is - it seems that the he

I would if someone can share his "real-life" experience with FlexJet (7-spindle) heads. We are currently running machines with Flex heads (4-spindle), which are very easy to maintain, but I suppose 7-spindle has more throughput. All comments are welc

We saw this condition over 3 years ago. It sometimes is called "champagne bubbles". The intemetalic formation is interrupted due to the micro voiding reducing mechanical strength. I discovered this on lead free test vehicles for a major computer

My personal favorite is the Siemens F series and the UIC GSM platform. Both Siemens and UIC have awesome resources for csp, flipchip and baredie processing - Siemens= Dan Baldwin from GaTech; UIC = George Westby from UIC labs. My second choice would

we have both flexjet and flexhead, we also have the new inline 7 head on some genesis dual beams we just put into operation. If you have a choice in flexjet heads take the inline 7. The flexjet 09 head is very labor intensive, stay away from them, e
