Our internal designers are employing SMT connectors that utilize a �PCB positioning boss� in conjunction with normal gull wing leads. The use of these devices is based on the advertised ability of the boss to prevent �mis-insertions� and assist in �

We have used thousands of them with no problems. They will not aid in "connector retention" unless you have a shear force at exactly the right angle. This is an advertising joke. They will help with alignment of the connector. Open your holes up so t

Hi Narksh, Well, for a quick over view, I'd suggest conveyors between all your equipment too. Also board handling equipment like bare board loader, buffers, shuttles... It really depends on how focused you want to get. When choosing any part of

As you are new to this - start with lots of hair and slowly reduce. Start with one good person. Spend the money on someone who knows the process, can set it all up, (including air, power, alignment, calibration, programming, troubleshooting, stenc

Since you got no reply, I will give it my best shot but we do not have a radial inserter because they are really expensive. I would start with Universal instruments. I think its http://www.uic.com. I think they still make them in New York. TDK and Pa

By "digital video inspection system", I'll assume you mean AOI. I have only dealt with one AOI system, YesTech, and in my opinion I'd say that AOI is much more consistent and advantageous than manual microscope inspections. Specifically, with the Yes

Many thanks for your reply. We would like to clarify two things; 1. We have recently purchased a vision system with oblique viewing facility to rotate the camera with 40x magnification, which we find useful to inspect fine pitch components . 2. Wh

Hello Just wondering if anyone has done trials on how long you can leave paste (tin-lead or pb free) on a board after you have printed it before it starts going 'off'? Thanks Chrissie FYI - have searched and found the 'pasting ahead' thread - jus
