I used to work for a company called Intelligent Reasoning Systems Incorporated. http://www.irsinc.com based in Austin Texas. They manufactured two different AOI systems depending on the component packages you wanted to inspect. The good thing about t

Ryan, It is a must that you try to get a partner in Japan that can help you market your product. Japan is not a very open marketplace. Many of the companies will only deal with other Japanese companies. I used to work at a company that was suc

Ryan, I agree with J.D, and emphasize that the single biggest issue is "partner". We are extremely succesful with our US manufactured product in the Japan marketplace, but this success is solely due to partnering with a very capable and talented "d

measuring Paste volume or at least paste height is an essencial part of any SMT process. You've got to control those input's.... Paste volume determines how much solder is available for your joint so theres a direct to joint reliability / PCB reliabi

You can buy plenty of paste height measuring systems today, ranging from full 3D laser systems to systems using an oblique light line which will measure the paste height only. I found that the lowest cost option was to attach a DTI to the focus contr

FYI- Toe Fillets have not been required per IPC 610b/c (they are nice to have though). Remember before Solder paste inspection equipment The Solder powder type/size, stencil type, and apertures are what defined volume. The need has not been until rec

I think we've miscommunicated....I don't use that thing for measuring paste height or volume as part of the process because it's not repeatable from one operator to the next. I use it more to measure radial tape and reel parts against EIA-486, actual

All arguments about using OA pastes on high frequency boards to eliminate alledged RF interference aside, is it acceptable to touch up SMT components on these boards with a no clean flux cored wire after wave solder? All of our wave machines are usi

Surprise, surprise. ;) Wouldn't think of it.... Yep. I'm not as concerned about two flux chemistries mixing and causing a substrate China syndrome as I am about the OA flux retained in voids and subsequently released in a touchup operation. If w

We've think that with seen solder shorts under BGAs after wave soldering the boards. In addition, it seems to be related to a certain soldermask configuration over the topside BGA vias.. THere is one vendor,A, that is applying soldermask after HASL,
