Custom Keyboard Development for OEM and ODM Programmes

Most input-device programmes stall because the keyboard is treated as a catalogue part late in the machine design, then has to be forced into a panel cut-out that was fixed months earlier.

Most input-device programmes stall because the keyboard is treated as a catalogue part late in the machine design, then has to be forced into a panel cut-out that was fixed months earlier. KEYU has manufactured metal keyboards, keypads, trackballs and touchpads in Shenzhen since 1995, and develops to customer drawings as well as producing from our own designs. This page sets out how a custom programme runs from your first enquiry to repeat production, and what we need from you at each point.

What This Covers

Development and production from customer-supplied drawings, or full design from an agreed requirement brief
Interface options covering USB HID, RS232, TTL, PS/2, RS485, IIC and matrix scanning ports
Key counts including 12, 16, 20 and 24 key numeric layouts and 61, 83, 87, 104 and 107 key PC layouts, with other counts customised
Construction choice between metal contact switch, membrane, conductive rubber and contactless electrostatic capacitance designs
Function options for backlight, Braille legends, combination and specific function keys and explosion-proof design
Desktop, embedded and panel-mounted stainless steel installation formats

Who This Is For

OEM machine builders integrating an input device into a fixed panel cut-out
Self-service terminal and kiosk developers needing a keypad matched to their enclosure
System integrators replacing an obsolete keyboard on installed equipment
Purchasing engineers sourcing a drawing-controlled part with a stable repeat supply

Stage By Stage

Each stage lists the problem it exists to prevent and how we handle it.

Enquiry and Communication of Needs

An enquiry that only says custom metal keyboard cannot be costed or scheduled, so the first reply is a list of questions and a week is lost.
Our first step is communication of needs against a fixed checklist: key count such as 16, 20 or 24, interface from USB, PS/2, RS232, RS485 or matrix, cable length, overall keyboard size, mounting as embedded or desktop, colour in stainless steel natural finish or black, whether backlight is needed and in which colour, whether key legends require Braille, and key format as flat or high. Answering that checklist once gives us enough to respond with a concrete direction rather than more questions.

Requirement Review

Buyers often specify a bespoke part when an existing product would fit, which adds development time and cost for no functional gain.
Before we quote development we review your answers against products we already build. Where a regular product meets the requirement we say so, because choosing one shortens delivery and saves cost. Customisation is proposed only where the interface, key layout, panel geometry or environmental duty genuinely rules the standard range out, and we state which of the two routes each requirement drives.

Design and Drawing

Panel cut-outs, fixing centres and cable exits are usually frozen in the host equipment before the keyboard exists, so a late dimensional mismatch means reworking the machine.
We work from drawings you supply, or we produce the design from the agreed requirement and issue it for your sign-off. Electrical scope is settled at the same time: USB HID, RS232, TTL, PS/2, RS485, IIC or matrix scanning output, plus combination keys and specific function keys. Working principle is chosen deliberately, since a metal contact switch, a membrane construction, conductive rubber contacts and a contactless electrostatic capacitance design behave differently on wear, noise and sealing.

Tooling and Moulds

A shape that exists only on a drawing can prove impractical or needlessly expensive to form once real tooling is costed.
KEYU holds over one thousand sets of moulds and runs CNC and sheet-metal equipment inside a wholly owned 4,500 square metre factory. Existing tooling is checked against your geometry first, and new tooling is raised only for features nothing on the shelf covers. Because forming happens in house rather than at a subcontractor, a tooling change found during development is handled by the same team that made the part.

Sampling

Approving a keyboard from renderings and a datasheet leaves key feel, legend legibility and panel fit unverified until production parts land.
Once requirements are confirmed and sample payment is arranged, we build samples to the agreed specification. Samples are produced and tested before despatch, so what reaches you has already run against the interface and function defined in the drawing package.

Sample Confirmation and Approval

Change requests raised informally after a sample arrives get lost, and the next sample repeats the same fault.
You receive the sample, test it in your own equipment and confirm it or raise a change request. Where changes are requested we repeat production and testing until the sample meets your requirement, and the confirmed sample becomes the reference for everything built afterwards.

Mass Production

Production units that drift from the approved sample force incoming inspection to argue about which unit is correct.
Mass production is released against the confirmed sample. Colour options such as stainless steel natural finish, black, gold plating and banknote spray, along with backlight, Braille and explosion-proof design features, are locked at that point so later batches repeat the approved build rather than a reinterpretation of it.

Quality Control and Certification

An input device that cannot show the approvals your market demands blocks the whole machine at import or at customer audit.
Products are built against the approvals named for our range: CE, RoHS, FCC, EMC, IP65, IP66 and IP67, IK07 and BIS. Sheet-metal processing runs under an ISO 9001:2015 quality management system. Tell us the destination market during requirement review and we will confirm which approvals apply to the configuration you are specifying.

Packing Shipping and After Sales

A keyboard that survives the factory but not the freight, or a repeat order that arrives different from the first, undoes the development work.
We ship to customers in China, South America, North America, Europe, Southeast Asia, Africa and the Middle East, and your drawings, tooling and approved sample stay on file with us for repeat orders and spares.

Custom Keyboard Development Questions

Do you work from our drawings or do we have to use your designs?

Both. We develop and produce keyboards from drawings customers provide, and we also design from a requirement brief when no drawing exists.

What information do you need before you can respond to a custom enquiry?

Key count, interface, cable length, keyboard size, mounting method, colour, backlight requirement and colour, whether Braille is needed, and button size and profile.

Should we customise or choose a regular product?

Choose a regular product wherever one fits, because it shortens delivery and saves cost. We tell you during requirement review whether a standard item covers your specification.

What happens if the first sample is not right?

You raise a change request after testing and we repeat production and testing until the sample meets your requirement. Mass production starts only after you confirm a sample.

Which key counts can you build?

Common numeric layouts are 12, 16, 20 and 24 keys, and PC layouts include 61, 83, 87, 104 and 107 keys. Other key counts can be customised.
