In 1983 Prolink embarked on a mission to write a Statistical Process Control (SPC) software program called QC-CALC™ to interface with various automatic inspection equipment. The need for an easy to use data collection and analysis software was apparent.

Many other SPC packages perform the same analysis functions as QC-CALC, but none offer the automatic database creation that has been our cornerstone. We have listened to customer’s needs and tailored the software accordingly. Our goal is to increase our customer’s awareness of process problems to save them time and money. The key is to obtain the data without adding cost and to report the analysis in a timely manner.
