Information Required from Clients

In order to offer you the exact product as per your specs, it is recommended that you provide the following information to us
Keyboard can be made with different specs depending on your application. Mainly we need three kinds of information to start a job:

 Mechanical

 Electrical

 Graphical/Aesthetical

Mechanical

Here you are requested to give dimensions of Keyboard, Display & LED locations, stud size & its location, switch size & its location, connector location and tail length and its location etc.

Electrical

Here you are advised to provide a detailed circuit diagram (logic Diagram) of electronic components with component specifications including pin numbers of connector. However we recommend to provide us the freedom to select connector pin numbers so that we can minimize the cross connections and reduce the complexity and improve the reliability of the Keyboard. In case of flexible membrane Keyboard, cost of the product will reduce as well.

Graphical & Aesthetical

It is important to select proper overlay material depending upon the application. The most common and economical material is Polycarbonate. We use special grade polyester which is very suitable for embossing and gives good chemical and scratch resistance. In order to make a impressive and attractive overlay, it is important to choose proper color, shade, font size, font shape etc.

Our graphical designers can provide a good design after customer provides the following details

 Application of the product (consumer, industrial, medical) etc.

 Enclosure color

 Functional characteristics of LED & Switch

You can choose a combination of matt and glossy finishes on the overlays. We can provide background illumination on selective areas of the Keyboard (Electro-Luminescent Technology)
The aesthetic look of the Keyboard can be further enhanced by embossing the switch and LED areas.
