CECO Industries

The client requested development of software and integration of hardware and software for a system to precisely measure the thickness of printed circuit board material. Mr. Weekley developed software to utilize a National Instruments M Series data acquisition board to measure the output of the two lasers, perform scaling, and accept operator control via a foot switch triggering a digital input. The software scales and displays measurements as they are acquired, evaluates and displays pass-fail status, and automatically records data.

The client requested development of software to perform Statistical Process Control (SPC) analysis of data files acquired by the dual laser thickness measurement system. Mr. Weekley used the LabVIEW SPC Toolkit and developed a highly interactive user interface to allow easy manipulation of parameters and display of the results.

Pacific Scientific.
The client wished to perform SPC analysis on accumulator weight data. Mr. Weekley developed software to read data from an Excel spreadsheet using DDE, automatically make calculations and display data in a run chart and a histogram. Mr. Weekley used LabVIEW and the LabVIEW SPC toolkit to develop a stand-alone executable that does not require the LabVIEW development system.
