About Isocom Ltd.

circuit design

Isocom Ltd, a privately owned UK company, was founded in 1982 to design, develop and manufacture optocouplers for the Commercial, High Reliability, Military, Aerospace and Industrial markets.

In 1984 H.R.H. Prince Charles opened Isocom Ltd’s new 5,000 sq. ft. custom-built manufacturing facility in the North East of England. The company has since focused its efforts on the production of optocouplers for the High Reliability/Defence sectors.

The result of this commitment was the approval of the facility to BS9000 in 1987. Isocom Ltd then became the first, and only, European manufacturer of BS9400 High Reliability ceramic optocouplers. .

Isocom Ltd’s aim is to continue its high-level investment in R & D, manufacture, testing and training to give the worldwide marketplace high quality innovative products. A result of this R & D has been the production of the world’s first 6 pin ceramic optocoupler.

Facilities, Skills & Expertise

As a specialist manufacturer, Isocom Ltd has the design, technology and manufacturing skills to satisfy even the most stringent or exacting customer product requirements.

It is this confident ability to undertake the most difficult projects that has earned us the respect of optoelectronics specifiers and technicians the world over.

Isocom Ltd’s manufacturing is centered around its purpose built factory in the North East. The 5,000 sq. ft. plant was designed and constructed to satisfy the requirements of both manufacturing efficiency and environmental control.

Throughout the facility, each stage of production, from the initial die attach process through to final testing, is supported by extensive investment in semi and fully automatic assembly and test equipment. Where necessary, Isocom Ltd has procured custom equipment to meet the demands of its unique product range.

Since its inception, Isocom Ltd has based its success on a unique blend of technologies and systems.

The cornerstone of the company’s product range is our command of hybrid micro-assembly. Through our own development programs and experienced engineers, Isocom Ltd is able to ensure that standard operations such as die attach, wire bond and lid seal are completed consistently and reliably. The assembly is based on Isocom Ltd’s own range of custom 6, 8 and 16 pin packages.

This expertise is further augmented by the company’s extensive knowledge of optoelectronic components and applications. We specify and design a whole range of enabling devices from LEDs through to integrated photodetectors. The techniques for the integration of these optoelectronic devices into the hybrid environment has now been developed to allow reliable, high yielding, yet flexible manufacture.

For many customers the foremost requirement has been for Isocom Ltd to develop products capable of meeting the exacting electrical and environmental requirements placed on them. This has been achieved through extensive in-house development and evaluation testing, and subsequently verified by the approving authorities.

The above activities are, of course, subject to the discipline and control of an approved quality system. This not only regulates manufacture, but through the implementation of appropriate controls, ensures long term continuity by way of disciplined development programs and structured responses to customer requirements.

Specialist Products

The combination of applications expertise, development facilities and manufacturing skills give Isocom Ltd an incisive problem-solving capability.Our engineers offer cost-effective quality solutions to design problems, drawing on families of 6, 8 and 16 pin packages and a large reservoir of optoelectronic die types, combined with testing tailored to individual customer requirements.

If you have a specific opto-electronic need for multi-channel devices, input current specifications, current transfer ratio selection, channel to channel matching, speed requirements, logic compatibility or custom reliability processing, talk to Isocom Ltd first.Whatever your requirement you can be assured you will receive a professional, comprehensive response from the acknowledged experts in the field.

Production Process

Isocom Ltd is committed to a quality and reliability that begins prior to any of the assembly stages. Before being released for production, all die are subject to 100% electrical test and visual inspection, and samples are drawn for more detailed electrical characterization and reliability testing. Isocom Ltd makes full use of manual, semi-automatic, and fully automatic die and wire bonders.

Hermetic lid seal is achieved through solder reflow, and 100% fine and gross leak testing ensures leak rate conformance, and provides a constant feedback of process performance during this key operation.

Use of automatic test equipment, coupled with high temperature handlers and temperature forcing equipment, ensures reliable efficient testing of both sub-assemblies and finished product over the full range of operating temperatures.

Temperature cycle, acceleration testing and burn-in are all an integral part of the company’s 100% processing of high reliability products.

High Reliability Process

Isocom Ltd supplies high reliability devices for applications typically requiring an operational temperature range of -55°C to +125°C, under extreme environmental conditions. In order to meet these requirements the company operates a reliability programme which invokes continual assessment and improvement of materials, processes and technologies.

Quality of Management

Isocom Ltd’s Quality Assurance system is a continuous programme established by management to constantly improve plant efficiency, reduce rework and interior workmanship, focus attention on production problem areas and to establish preventative measures.

Quality Awareness is promoted throughout all phases of design, development and production. This is achieved by the establishment of good communications between all levels of management, and subsequently through an operator’s pride of workmanship.

Design Quality

Design reviews throughout development and pre-production runs of new products promote participation between engineering, production, QA and Marketing Departments. This participation encourages maximum use of the combined expertise and ensures a smooth transition from product design into a manufacturable product which matches customer needs.
