  About Us



To assure the quality of its product, CBD employs modern testing equipment and techniques, including In Circuit Testing and Automatic Optical Testing.

In Circuit Testing

CBD offers in circuit testing (ICT). This, in conjunction with automated visual inspection, offers the greatest degree of quality. A defect such as bare board opens and shorts, component function and tolerance, are easily identifiable with the addition of ICT.

ICT consists of a computer controlled test and measurement system. This "Bed of Nails" fixture and test program will verify component presence, value, tolerance, polarity and orientation of components. ICT will also identify opens and shorts in PCB foils and solder joints.

Add ICT to your PCB assembly. Contact us for a quote on fixturing and programming costs.

Automated Optical Testing

CBD inspection criteria meet or exceed IPC-A-610 "Acceptability of Electronic Assemblies" as well as ANSI/J-STD-001 "Requirements for Soldered Electrical and Electronic Assemblies". This is possible in part through the use of (AOI) "Automated Optical Inspection". The OMRON VT-WIN© has image resolution from 13 to 50 µm. This allows high-speed inspection of leaded components from 0.3mm pitch and 0402 chips. These inspection capabilities also apply to lead-free applications.

Inspection Categories:


  • Bridging
  • Excessive Solder
  • Wettability
  • Blow Holes
  • Presence/Absence
  • Solder Balls 


  • Presence/Absence
  • Upside-Down
  • Shift/Skew
  • Polarity Marking
  • Lifting
  • Pin One Marking
  • Un-Inserted
  • Lead Bends 

The full spectrum, angled color-viewing system, ensures accurate results from the most challenging board layouts.

The CCD camera captures these colors as they reflect off the board's surface, producing a two-dimensional image that conveys three- dimensional information to image processing.
