Telecommunications

As one of the most important parts of social, cultural and political activity, telecommunication is continuously changing. Driven by increased competition and new technologies, this evolving industry, not only includes the traditional area of local and long distance telephone services, but also technology based services including wireless and mobile communications, the Internet, fiber optics and satellites.

For telecommunication systems and equipment to operate as required, manufacturers need to ensure the highest quality and efficient performance of the parts they produce. Both visual inspection and dimensional measurement of parts are important aspects of the manufacturing process.

Rigorous inspection of telecommunication parts

Visual inspection is the most widely used method of detecting and examining potential surface flaws. Whether it’s during incoming, in-process or final inspection, telecommunication parts must be rigorously inspected to ensure trouble free performance.

The Mantis Compact and Mantis Elite stereo microscopes have proved invaluable tools in the visual inspection of connectors, PCB’s, isolators, converters, fiber optic bundles and many other telecommunication components. From deburring applications to visual inspection of pins in connectors, the fatigue free viewing and superb image quality offered, have increased productivity and reduced scrap rates.

Dimensional measurement of telecommunication components

When it comes to ensuring the quality and performance of their components, manufacturers employ analysts whom carry out various tests to verify that the products produced, conform to international industry standards. Various dimensions must be measured to establish whether or not components meet the specifications outlined in engineering drawings and CAD files.

As the telecommunication industry evolves, component parts are becoming smaller and more complex, making them difficult to measure. Manufactures are thus looking for ways to improve the efficiency and accuracy of this critical step in the manufacturing process.

World renowned mobile phone manufacturers and their suppliers, use Vision Engineering’s Hawk systems to measure various small, complex electronic and mechanical parts. The parts measured, must fall within tight tolerances to ensure they are fit for purpose.

The Hawk family of optical and video non-contact measurement systems offer high accuracy and repeatability. From simple 2-axis optical measuring microscopes to 3-axis video edge detection measuring systems, all Hawk systems include the patented Dynascope head which allows detailed visual inspection to be performed simultaneously.

Batch inspection and tolerance conformance

A typical example of where the Hawk measuring system is used is in the inspection of mobile phone connectors, where batch samples are inspected and measured or when a problem is suspected to check for form tolerance.

Operators could simply randomly remove one connector from the machine and take some simple point to point measurements (no programming) to quickly find if the mold tool needed resetting. Image capture software QC200 with the ability to email results to other facilities, allows for training/comparison purposes, as well as for inspection for size of mold marks etc.
