Inspection vs. . Measurement Smart Sonic Inspection Systems § Check 100% of Part – Ensure no bad parts ship § Output is Pass/Fail vs. User Defined Tolerance § Low Cost § Overlay CAD and Image - Very Easy to Program § Fast - Inspect parts with millions of features in minutes § Multi-Purpose - Inspect multiple part types and create data § Can also provide some measurement capability § Complimentary to measurement systems - many customers have both. (Measurement systems not able to inspect 100% of part)

Defects Found by Inspection 1 mil blockage Wafer Bump Stencil Over 350, 000 Apertures – 100 um diameter

Inspect. Scan VPI

Pre-Production Process Control PCB Assembly Inspect. Scan VPI Virtual Product Inspection With a single system check: (Stencil. Scan Lite) § § § Design - holes, slots, real estate, manufacturability… Components - multi vendor, shape, color, size… Bare Boards - FR 4, Ceramic, Flex (multi vendor, variables…) Wet Boards - paste, adhesive, coatings, etc. Stencils/screens - stretch, missing, blocked or damaged apertures All variables come together in VIRTUAL system before Production First article inspection and SPC during production And in addition, same system can: (Assembly Module) § § Create assembly programs from CAD, Gerber data or scanned images First article inspection of loaded boards - SMT, Through hole, Connectors, etc. Create stencil Gerber data Create component vision files for SMT placement machines (Component Module)

Pre-Production Process Control PCB Assembly Inspect. Scan VPI Bare PCB’s Flex Circuits Stencils Components PCB’s with Paste or Adhesives Loaded PCB’s

Pre-Production Process Control Hybrid Microcircuits Inspect. Scan VPI LTCC or Thick Film Print Screens Holes in Substrates Artwork Substrates with Paste or Adhesives Loaded Substrates

Process Control and Inspection Functions

Process Control & Set Up Store Images of All Assembly Steps and Gerber/CAD in Layers to Easily Find Issues before Production! Compare PCB to Gerber • Find PCB Problems before Production • Compare to PCB or Stencil Gerber Input Gerber Scan PCB in Color Convert to Raster Overlay and Inspect

Process Control & Setup Compare Stencil to Gerber • Find incoming stencil problems • Compare to original or modified Gerber cut file • Find blocked apertures or stretch after cleaning Input Stencil Gerber Scan Stencil in Color Convert to Raster Overlay and Inspect

Process Control & Setup Compare PCB to Stencil • Avoid production problems • Similar method to compare new PCB to PCB in production Scan PCB in Color Convert PCB to Raster Scan Stencil Overlay and Inspect

Process Control & Setup First Article Component Placement Inspection • Existing method such as assembly drawings or overlays highly prone to operator error and overlays add cost • Overlay CAD on board image for operator verification • Eliminate errors - Zoom in or out, CAD info available on status line Scan Populated PCB in Color Input and Overlay CAD Step to First Component Step through Remaining Components

Process Control & Setup First Article Component Placement Inspection • View of full screen including status line with CAD data

Process Control & Setup Other Capabilities: • Inspect Artwork or Emulsion Screens vs. . Gerber data or Golden Part • Compare Components from Different Suppliers • Inspect Wet Material versus Gerber or Golden Part

Inspection Process In seven quick and easy steps! 1. 2. 3. 4. 5. 6. 7. Import Gerber file Scan stencil or screen at appropriate dpi Super-impose scanned image and Gerber Fine align scanned image and Gerber Inspect automatically Review errors Print certification report

1. Import Gerber File The imported Gerber is displayed in green

2. Scan The PCB, stencil, paste, etc is scanned at the appropriate dpi and displayed in blue

3. Overlay Scanned Image and Gerber The scanned image and Gerber image are super-imposed at a common point

4. Fine Align Any remaining skew between the two images is corrected using the “Fine Alignment” function

5. Inspect The automatic inspection process offers a variety of inspection levels and options to verify aperture position, shape and size

6. Review Errors are highlighted in red and sequentially numbered for easy viewing

7. Print Certification Report Add the report to any letterhead or certificate
