Product Introduction
The Holy PCB Copper Thickness SPC Analysis System is a quality analysis software independently developed by our company. It is designed for copper thickness measurement data from the PCB electroplating process, providing a complete SPC workflow from data acquisition and control chart analysis to process capability evaluation and report output. The software can directly acquire data from the copper thickness measurement instrument via serial port, or import Excel/CSV/TXT files or manually enter data. It features a tech-style dark interface with 6 functional tabs, suitable for on-site analysis on electroplating lines and daily laboratory use.
Main Technical Parameters
- Data Acquisition: Real-time reading of copper thickness measurement instrument data via RS-232 serial port, with customizable serial port parameters.
- File Import: Drag-and-drop or browse import of Excel / CSV / TXT files, with automatic recognition of numeric columns; supports manual batch entry and single value addition.
- Control Charts: X̄-R (Mean-Range), X̄-S (Mean-Standard Deviation), I-MR (Individual-Moving Range), Run Chart (including run test).
- Distribution Analysis: Histogram with adjustable number of bins, normal distribution curve fitting, specification limit display.
- Normality Test: Shapiro-Wilk and Anderson-Darling methods.
- Process Capability: Calculation of Cp, Cpk, Pp, Ppk indices, grade evaluation (A+ to D), defect rate / PPM estimation.
- Outlier Detection: IQR method and Z-Score method, with automatic highlighting in the table.
- Data Management: Table sorting / searching, export to CSV / Excel, project file (.spc) saving and loading.
- Report Output: PDF report with Chinese, multi-worksheet Excel report; charts can be exported as PNG / PDF / SVG.
- Auxiliary Functions: Generate test data according to normal distribution (support outlier simulation) for method validation.
Product Features
