Not sure if you need help with the calculations or the application, so from the beginning: d=defective parts, p=number of parts, dpm=defects per million parts In a nutshell, d/p=dpm/1000000, so dpm=d/p*1000000 We use dpmo (defects per million op

With hundreds of opportunities for problems to surface during the electronics manufacturing process, it is a credit to the manufacturing and engineering talent of the industry that planes fly, pacemakers keep hearts beating and phones are at the ready to provide Facebook updates or even make a call. To keep these dedicated professionals up-to-date on the latest causes and cures for assembly and solder defects, IPC and the U.K. National Physical Laboratory (NPL) have teamed up to sponsor a free webinar at 12:00 pm (noon) U.S. Central time on January 27, 2011 — a precursor to the hands-on, three-day Process Defects Clinic that will be held at IPC APEX EXPO in April.

As six sigma (6) and better processes are demanded for higher yields and as organizations move from measuring defects in terms of parts-per-million (ppm) towards parts-per-billion (ppb), the resolution of extant control charts is becoming insufficient to monitor process quality. This work describes the development of a new statistical process control (SPC) chart that is used to monitor processes in terms of defects-per-billion-opportunities (dpbo). A logical extension of the defects-per-million-opportunities (dpmo) control chart, calculations used to derive the dpbo control limits will be presented and examples of in-control and out-of-control processes will be offered.

This paper describes a model developed to calculate number of redundant good die per wafer. A block redundancy scheme is used here, where the entire defective memory subarray is replaced by a redundant element. A formula is derived to calculate the amount of improvement expected after redundancy. This improvement is given in terms of the ratio of the overall good die per wafer to the original good die per wafer after considering some key factors.
