ScanCAD has been supporting solder paste stencil and emulsion screen fabricators and users for over 20 years. We are the global leader in flexible, multi-purpose screen and stencil inspection systems. Our system captures calibrated high resolution images, overlays original CAD or Golden Part data and performs an automatic inspection to detect errors BEFORE production. By eliminating errors prior to production, we are able to significantly decrease costly rework and scrap

The ScanCAD system can inspect all types of stencils, screens and even the precision phototools used to create emulsion screens. Whether you are inspecting an incoming stencil or screen to ensure conformity, confirming all apertures were properly cleaned in between runs, or performing a periodic check to ensure wear is within tolerance; our systems are a critical component of process control.

ScanCAD Inspection systems are a critical component for process control.

Unique Niche

Independent verification of stencils and screens is mandatory for ensuring no bad parts are used in production.  Even one defective stencil or screen defect can be very costly due to scrap, rework or even product recall.  These systems can also be used as general purpose measurement & inspection systems for parts such as bare PCB’s, pallets, carriers, tooling, ceramics/LTCC, solder paste, glue, etc.

Unique Technology

Internally developed software coupled with our low-cost vision platform and NIST certified calibration equipment ensures that our system is a solution that is custom tailored for your application. Our hardware and software have been specifically designed to maintain an excellent price-performance ratio, maximize your ROI and provide a unique set of tools for effective and efficient inspection & measurement providing 100% traceability and SPC data for your ISO certification.

Unique Process

Over our thirty years in business, we have continuously improved our process to support cutting edge technology.  Our ability to inspect relative to both the fabrication data (eg. cut file for laser stencils) and the original design file (eg. PCB CAD file for stencils), as well as automatically compare directly against an actual part (eg. PCB) sets our system apart.  In addition, the same system can also generate fabrication data that exactly matches the substrate (eg. Creating stencil data for an existing PCB) which has been proven to reduce production defects.

A 43% reduction in solder paste defects can be achieved by simply adjusting stencil data to match a job lot of PCBs. Why compound process errors if you don’t have to?  It’s time to up-level your process.

A Case Study

A single missing capacitor aperture on a low cost solder paste stencil caused a massive, very costly automobile recall.  This defect was not caught by the stencil fabricator’s manual inspection method before the stencil was shipped.   Nor was it caught by the stencil user through their manual inbound inspection or by their electrical test after the board was assembled, since there just was enough solder on the HASL pad for the electrical test to pass.  The final product failed in the field after about 6 months due to vibration and temperature variation. All of this could have been avoided by simply checking the stencil with a ScanCAD automated stencil inspection system immediately prior to placing the stencil into production.

Quality issues are unpredictable and expensive. A low cost system combined with a five minute process can save an enormous amount of money, time, and energy in the long run.
