The in-house test engineering team provides development for in-circuit (ICT) and functional test, while strategically formed alliances with external organisations complement this to offer customers an unrivalled test strategy.

Test and Inspection Strategies

• Automated optical inspection (AOI)

• X-Ray

• In-Circuit, flying probe and functional test

• Environmental and ESS

AUTOMATIC OPTICAL INSPECTION (AOI) - is a powerful tool and enables the monitoring of compliance within high-density SMT assemblies. Variability is present in all manufacturing processes, in order to minimise them they first need to be detected, measured and then corrective action implemented.

Manual inspection has limitations, especially with respect to coverage and feedback. The Omron VT-RNS system deployed at Axiom enables:

• 100% inspection coverage

• Measured feedback to the manufacturing process

• Advanced lighting and optics

• Image processing

• Inspection accuracy and repeatability

• Real time process improvement

• Real time programming

• Cost effective solution

X-RAY INSPECTION

Axiom’s investment in the latest X-Ray integrated digital acquisition technology is recognised as a vital cog in the test regime for the manufacture of printed circuit board assemblies.

The Dage XD7500VR X-Ray inspection system enables enhanced analytical quality at a faster throughput using sub-micron minimum feature recognition providing superb image quality for BGA, flip chip and chip scale package inspection on printed circuit boards as well as semiconductor devices. By providing highly improved digital real-time X-Ray images, enhanced resolution, image manipulation, extensive greyscale definition and oblique angle views of up to 70 degrees, the highest levels for investigation of joint quality can be assured.

Capabilities include:

• Automated inspection routines

• Automatic BGA and die-void measurements

• Real-time digital X-ray inspection

• 16-bit image processing

• 1.3M pixel enhanced resolution

• >65,000 greyscale levels

• 950nm feature recognition

• 70 degrees oblique views

• 360 degrees rotating view

• Comprehensive data recording

IN CIRCUIT, FLYING PROBE AND FUNCTIONAL TEST

Axiom has extensive experience of multiple test platforms, which are supported by a test engineering team dedicated to continually evaluate product test flow and cycle time efficiency.

Through this evaluation, test costs, first time yield is improved upon, downtime is reduced and test costs minimised.
 

A wide range of of Automated Test Equipment (ATE) is utilised offering the flexibility of ICT (bed-of-nails), Flying Probe and functional test capabilities.

Platforms include:

• Okano

• Teradyne

• Wayne Kerr (Cimtek)

• Flying Probe Takaya APT-9411

With maximum test coverage being complimented by improving existing customer test systems or the development of new, cost effective solutions:

• Customer test network integration

• Axiom developed solutions

• Commissioned test solutions

ENVIRONMENTAL AND ESS

In addition to ICT, PCBA and functional test solutions, Axiom provides its customer design teams with a complete suite of additional environmental test capabilities, enabling a full turnkey service offering enabling product shake-down and debug.

• Humidity

• Environmental Stress Screening (ESS)

• Burn-In and Soak

• Vibration

• Drop test

• EMC Pre-Compliance (UKAS approved)

• EMC Compliance (UKAS approved)
