Automatic Stencil and Screen Inspection

ScanSTENCIL

ScanSTENCIL™ is a fully integrated, stand‑alone measurement and inspection system designed for stencil and screen verification after fabrication. Using a high‑resolution, calibrated flatbed scanner with Windows‑based software, it delivers fast, 100% inspection of apertures for presence, shape, and size—even down to 0.002” (0.050 mm).

By ensuring accuracy, supplying Gerber data, and supporting multiple stencil production methods, ScanSTENCIL helps manufacturers maintain quality, reduce errors, and streamline the stencil production process.

Automated Stencil and Screen Measurement & Inspection System

ScanSTENCIL is a fully integrated, stand-alone measurement and inspection workstation for use after stencil and screen fabrication or other machined, etched, e-form or laser cut operations.

Uses a PC Windows-based software package integrated with a high-resolution, calibrated, A3 size flatbed scanner. This combination allows inspection of both stencils and screens for accuracy and the ability to inspect 100% for absence/presence and correct size of thousands to millions of apertures.

✔ Quality: 100% automatic inspection of screen/stencils for absence/presence, shape and size of apertures
✔ Accuracy: Verify absence/presence of apertures as small as 0.002” (0.050 mm)
✔ Usability: Supply production with required Gerber data
✔ Flexibility: Use one software product to create data required by the stencil production process

Product Functions

Create Stencil Fabrication Data

Adds flexibility to the stencil and screen inspection process. Utilizing its calibrated scanner, ScanSTENCIL inputs stencils, screens, silver or diazo film, mylar images, technical drawings, actual PCBs or original hand-taped designs. With these inputs, ScanSTENCIL is able to verify cut stencils/screens for accuracy, size and blockage, as well as producing necessary Gerber data for stencil/screen production.

Automatic Features

Offers various functions that quickly and automatically create necessary Gerber and verification data:
• Absence/Presence of Apertures
• Confirm Proper Aperture Shape and Size
• Compare Stencil/Screen vs. Gerber
• Compare Stencil/Screen vs. PCB
• Confirm Proper Aperture Position
• Create Stencil Files from Boards/Films
• Automatic Inspection Accuracy Level Detection

Verification

Verify the accuracy of the parts and (Gerber) data. The “Local Micro Alignment” (LMA) option allows for checking apertures as small as 0.002” diameter (0.050 mm)

Additional Applications

Creates Gerber files and other data used in stencil production, including: Silkscreens, Soldermasks, Padmasters, Stencil Files, Panelized Images, DXF, NC and Gerber-274x files, etc. ScanSTENCIL permits fast and accurate comparison of stencils/screens to bare PCBs bringing automation and increased productivity to QC departments.
