Design and Development

Closer to you, closer to the solution

Electrical and electronic device designs are becoming increasingly miniaturised and complex, based on the explosive growth of information technology. As these electronic devices must offer continuously higher reliability and operability, the complexity of design requirement is increasing at an exponential rate.

Therefore focusing solely on connectors, JST has developed a worldwide organisation structure and internal system that directly links our customers' engineering teams with our development staff, who have complete decision-making authority.

JST's corporate commitment to technological innovation is quickly seen at a host of advanced development facilities throughout the world. A good example of this is at our Engineering Centre in Tokyo, which has incorporated N2 reflow soldering equipment for the study of fine pitch SMT connectors.

As part of this worldwide organisation structure, JST (UK) Ltd has also developed a dedicated design team to address and meet the demands of our customers. Whether it's a modification of an existing product or a completely new design specifically for our customers' application, we will assist step-by-step all the way.

If you have any questions regarding any of our products then please contact us on phone no: +44(0)1986 874131, or email us at

Tooling Technical Support

Our experience is your resource.

JST have a 'total package philosophy' regarding the supply of terminals / connectors and related application tooling. It is our belief that the supply of application tooling is a fundamental part of our business and this is reflected in our comprehensive range of application tooling.

Whether the requirement is for a hand tool, a fully automatic wire termination machine or any stage in-between, JST has product matched application tooling available to fulfil our customer's requirements.

Because the application tooling is manufactured to the same stringent quality standards as our terminals and connectors, we can confidently guarantee that the resultant crimp produced by these tools is of the highest quality and conforms to the tolerances specified for the product.

JST's application tooling is supported by a dedicated team of qualified engineers who are always on hand to provide you with technical support and assistance.

JST (UK) Ltd. have an extensive inventory of more than 3,000 different spare parts stored in a 'state of the art' parts retrieval system, which enables us to quickly locate and despatch any part to our customers that may be required. It is our proud boast that we can supply most spare parts that are required by the next working day after the order is received.

This is a fundamental part of our customer service commitment and we believe that our customer support is second to none in the UK, Ireland, India and South Africa.
