SOLDEF: Solder Defects
In mistat: Data Sets, Functions and Examples from the Book: "Modern Industrial Statistics" by Kenett, Zacks and Amberti
SOLDEF R Documentation
Solder Defects
Description
Solder defects on 380 printed circuits boards of varying size.
Usage
data(SOLDEF)
Details
In SOLDEF we present results of testing batches
of circuit boards for defects in solder points, after wave solderings. The batches
includes boards of similar design. There were close to 1,000 solder points on each
board. The results Xtare number of defects per 10^6 points (PPM). The quality
standard is λ_0 = 100 (PPM). λ_t values below λ_0
represent high quality soldering.
In this data file there are N = 380 test results. Only 78 batches had an X_t value
greater than λ_0 = 100.
