IMHO, depending on whether its a regular run model, or a properly designed/setup pilot run model, getting a mean 75%-95% First Pass Yield (FPY%) is possible as a benchmark target. This is derived from your manufacturing history capabilities, and requ

...reasonable benchmark. 30 to 100DPMO is considered world class. All else? Well lets just call it "not-so-world-class". :) Dean

With totally stable screen print (solder paste), placement and reflow processes, what is a world class target first time yield for good pcbs? How bad is 65% FTY. Your views would be welcome.

Did I miss something, is there a competition, a championship out there? World class with a bicycle or a racing car ? And still there�s the question, what�s the measure ? Stock quotes, workers, products, customers, nature ? It wouldn�t be "world cla

I personally would not get involved with any technology as old as the Q4C. I worked in a factory that had about 20 of those and was not impressed. It seemed like there was always some problem (electro/mechanical) and their service was not "world cl

Does anyone know there a standard matrix of clearances part to part for Class 2 and Class 3 board design. IPC does issue a preferred matrix but they are so liberal they not so useful in the real world. Any suggestions would really be appreciated.

Electrically testing components is an age-old practice of the past. True "world class manufacturers" like to minimize, or even eliminate incoming inspection of ANYTHING - the theory being....a world class manufacturer should have such awesome relati

John, I hope your figures or numbers are part of your SPC process. Our management loves this stuff. I think the production line, world class or not would reflect the attitude of the people working on it(keep that between you and me) management does

I have a number of hopefully easy questions: 1. Are there significant differences in the ease of change-overs and set-up among different equipment manufacturers? For example, are Siemens Siplace machines truly more modular than others? 2. Is ther
