we tested this kind of part about 3 years ago did a few prototypes I did'nt know how it was going to work but our old amistar picked it and placed it just fine used a small nozzle with a o-ring on the end of it I think it did ok going across the wav

Hello Mark, I wish it were that simple so I could direct you to a particular manufacturer and stencil cleaner model. Unfortunately, there are several issues complicating the process of cleaning all these applications in one machine. First and fore

Hi all, Assuming that i were to design a PCB and there are multiple components, what is the minimum spacing required to ensure that i won't have problems in my SMT process later on? Also, is there a minimum component stand-off height spec as well?

For your pad layout and spacing between components, look here: http://portal.ipc.org/Purchase/ProductDetail.aspx?Product_code=77b562c1-b8f8-db11-8a6a-005056875b22 For your standoff height in SMT, we do not concern ourselves with standoff height. It

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl

Yes, courtyard gives you the space requirement of a component. Sometimes, the working space of a rework tool takes precidence, though.

Yes, unfortunately a lot of datasheets these days do not contain the temperature resistance to determine if it can handle the PIP application. In the past I have always used a 250 C at a min of 5 sec for the material. Also, the part should have sta

Screen printing has much lower profile than dispensing. So it is suitable for chips without body stand-off, (Even sot23 has stand-off). But is is much faster. Dispensers can not catch up with some chip shooters.

Some people involved in PCB assembly process claim that SMD components reflow soldering problems are often caused by traces running under a component. According to this claim, trace (or any copper) covered by solder mask and placed under SMD componen
