Visual Inspection
Production and inspection personnel have vision tests performed biannually to verify visual acuity. Visual inspection is performed by production operators and inspection personnel using the designated workmanship standards. Visual inspection may be with magnification (using equipment such as the Vision VS7) or with the naked eye. An Ersascope is used for visual inspection of BGA and SMT solder connections.
X-Ray Inspection
X-Ray inspection can be performed to provide a non-destructive, fast and thorough examination of the solder joints and electronic components on a printed circuit board X-ray is used for the non-destructive testing of PCB assemblies, semiconductor packages (BGA’s and leadless devices), encapsulated components, mechanical assemblies and other similar devices requiring x-ray test. Defects such as internal cracks, delaminations, inclusions, improper mechanical fit or excessive porosity are easily visualized without damaging the product, so that it might be repaired instead of destroyed. When combined with full automation and offline analysis, this allows a number of products to be checked with minimum input from the tester and minimum deviation from a standard test.  Not only does this ensure that all products are tested equally thoroughly, it also gives added depth to the testing capabilities at Matric. The Y-Cheetah features a point-and-click style graphical interface. It also provides for high performance imaging by using a digital flat-panel detector, making it much easier to interpret possible failures.
3D Automated Optical Inspection (AOI)
3D Automated Optical Inspection (AOI)To complement our quality control inspection and testing methods, Matric offers automated optical inspection (AOI) of in-process PCB assemblies. AOI offers a more accurate and efficient alternative to visual inspection, involves comparatively less programming time than other MDA devices, and helps to deter solder joint defects and latent failures. The latest AOI technology at Matric is 3D AOI. 3D AOI system measures the true profilometric shape of components, solder joints and patterns on assembled PCB’s with true 3 dimensional measurement.  The 3D AOI will flag and quantify a variety of defects including: missing, offset, rotation, polarity, upside down, OCV, solder filet, billboarding, lifted lead, lifted body, tombstone, bridging and more.
In-Circuit Test Equipment
In-circuit test is utilized for the automated testing of assemblies. Programs can be developed to verify the functionality of PCB assemblies.  In-circuit test can be used to measure component values, find solder bridges, and detect open solder joints. It can also be used to power up the assembly and verify functionality. The Series 5 ICT system at Matric offers new analog measurement technology together with the industry’s fastest 12 MHz hybrid pin card. In addition, the new Agilent machine was ordered with the following options:

  • The ability to be able to test boards with up to 1296 nodes
  • Boundary Scan: Boundary scan is a method for testing integrated circuits on PCBs.
  • Established stimulus and responses are given to ICs to determine whether pins are shorted or open on the device.
  • The ability to program flash devices
  • VTEP: VTEP is a combination of hardware and software techniques, which enable improvements over the noise characteristics, stability, accuracy, and repeatability of measurements.

A custom bed of nails fixture is required to be purchased to test each unique board design.

MDA Testing
A flying prober is available to test both SMT and through-hole assembled printed circuit boards for manufacturing defects. Being a fixtureless test machine, the flying prober avoids the high cost of bed of nails fixtures; it is ideal for contacting leads of fine pitch SMT components. Test programs for most printed circuit board assemblies can be developed from CAD data in about a day. Interfaces are available for most common CAD packages. The flying prober is equipped with optional features to detect open solder joints on most digital ICs. The flying prober also has a vision option, which permits a visual examination of components that cannot be electrically verified, such as bypass capacitors or capacitor polarity.
Functional Testing
  • Trained electronic technicians use standard electronic instruments to bench test and troubleshoot electronic assemblies in accordance with written test procedures.
  • Where justified by production volumes or other requirements, custom and / or computer based functional testers (board level and / or system) are developed to partially automate the functional test.
  • Automatic functional testers (ATE) are also available for testing and troubleshooting electronic assemblies.
  • Test failures are troubleshot, repaired and retested.
  • Test records can be in the customer format, and maintained on file at Matric or provided with each shipment.
Cleanliness Testing
  • Where specified, the cleanliness tester is used to verify printed circuit board assemblies are free of surface contaminants.
  • Also referred to as “ionic contamination testing”.
  • Contamination is expressed as a sodium chloride equivalency (micrograms / sq. in.).
  • Test methodology is in accordance with IPC-TM-650, 2.3.26.1 (static method).
  • Board sizes up to 15″ X 20″
Environmental Testing
