I am not using a solder pallet, I don't think the problem is contamination related, because these parts are on some of our other assemblies, and they're being waved with no problems. The problem seems to be mainly on our panelized boards for some rea

It sounds like you may be thinking of two different test methodologies. What is required? Bare-bard testing, to verify pcb fabrication? Or populated board testing, to verify manufacturing? If it's bare board testing, the fab house should advise a

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

I don't understand so please explain in more detail. You say ~0.3mm shifted. In what direction is the paste shifted? is it shifted the very same directions on all panels? Only on this product or even with regular pcb:s? What is the size of the panel

Dave, I would not recommend use of a multi-meter to determine high quality DI water resistivity readings. There are a number of reasons including a multi-meter�s lack of temperature compensation. We use a Myron-L resistivity meter to accurately de

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
