Hello Is there anyone who can give me some information regarding yield from gluing 0603 Is there any other problems that you might have had.

LINEAR LGA DC/DC low yield

We are facing 50% yield soldering Linerar (uModule) DC/DC LGA. The failure is characterized as "flactuation of output voltage." Can some one had the same failure?

Hello Is there anyone who can give me some information regarding yield from gluing 0603 Is there any other problems that you might have had. We glue bottom side 0603's but have changed our pad spacing to accomodate tolerance requirements

Follow the manufacturers reflow spec in the application guide.

Typical first pass yield in electronics

I'm a mechanical engineer and we buy electronic pressure sensors and switches. In doing quality audits, I need to understand what "best practice" will yield in terms of conforming product first time through the manufacturing process? Any data out t

On circuit board assemblies first pass yields need to be above 98%, if a supplier is below this level it is a indication that: he has poor control of the manufacturing process; Poor component selection (price over quality; excepted a poor design from

I am working to improve the yield on a SMT line and am trying to find out a benchmark figure, anyone who could guide me to the expected yield for soldering related issues on a board containing approximatly 4000 joints I would be very greatfull.

I would trust that you are benchmarking some design rules as well? Yield is directly related to design as well as process capability. anyway 95% is not a bad first pass yield at all, and I would tend to think that that is a little high when dealing

The DPMO is a far better measure - first pass yield doesn't give you any indication on quality or effectiveness of test step. If you want 100% first pass yield, test nothing - works every time - you see where I am coming from..........
