Trustable Keyboard PCB Supplier in China
Consons is an experienced EMS provider and offers you one-stop keyboard PCB solutions, which cover Bare PCB manufacturing, component sourcing, and PCBA assembly. Our services include PCBs for mechanical keyboards, Bluetooth wireless keyboards, and other special-purpose keyboards; we also offer various layouts, including 60%, 75%, 80%, and 100%.
During manufacturing, we use dedicated reflow soldering profiles (temperature difference ≤5°C) to strictly control RGB LED color deviation and dead LEDs, ensuring consistent key feel and lighting effects across every keyboard PCB. The enhanced pad design also improves soldering strength and prevents component detachment.
For every order, Consons provides 100% key trigger testing and lighting effect inspection. Moreover, our production lines are ISO9001 certified, fully comply with IPC-A-610 Class 2/3 acceptance standards, and meet RoHS 2.0 environmental requirements.
Types of Consons Keyboard PCB
This is the most common solution. The keyboard connects to the computer through a USB Type-C cable, and the design is relatively simple.
This type of PCB adds a Bluetooth controller chip and antenna circuit based on a standard keyboard PCB. It connects to the devices through the Bluetooth protocol.
It connects to the computer through a 2.4GHz receiver and is usually paired with a USB receiver. It has lower latency and is suitable for gaming applications.
It supports three modes in one design: wired, Bluetooth, and 2.4GHz wireless. The three modes can share the same main controller or use a time-sharing RF circuit.
Excellent Service Quality from Consons
Our manufacturing process supports these two soldering methods. Also, hot-swappable pads will be designed with teardrop compensation and increased annular ring width by default.
Our production lines have high efficiency, enabling a daily output of 10,000 keyboard PCBAs and ensuring on-time shipment according to the agreed delivery schedule.
For mainstream RGB LED models such as SK6812 and WS2812, we set reflow soldering profiles individually for each project.
The shipment warpage control standard for our keyboard PCBs is ≤0.75%, which is stricter than general IPC requirements.
We fully support 60%, 75%, TKL, 100%, Alice, Ortholinear, and other keyboard layout designs; irregular-shaped PCB CNC milling and complex cutout slot designs are also available.
USB differential signal lines are controlled to 90Ω ±10% impedance, and are suitable for keyboard designs with strict requirements for USB 2.0/3.0 and wireless RF routing.
We provide FPC flexible PCB and rigid-flex PCB manufacturing, supporting Gasket structure connection cables and foldable hinge areas.
The prototypes and mass production use the same production lines, PCB substrate brands, and process parameters. The quality verified during the EVT/DVT stages will be fully reproduced.
Full Traceability Throughout the Entire Process
Every keyboard PCB or PCBA we produce has a unique batch traceability code, applied by laser marking or label attachment, and remains permanently readable. When an issue occurs, you do not need to investigate step by step. Simply check the traceability information to identify the root cause.
With a simple scan, you can access the complete process data record of each board, including the original PCB substrate brand, production time for each process step, SPI/AOI/X-Ray inspection data, etc.
Complete Testing Services From Consons
For MCUs and other active components, we only purchase from the authorized distributors and first-tier distributors. We will strictly verify the consistency of the original manufacturer labels, lot codes, and datasheets to avoid receiving refurbished components.
For RGB LED chips, we also carry out comprehensive inspections based on color binning, brightness levels, and package sizes.
For your order, we will design a specific FCT fixture based on the keyboard layout and functional logic. Every keyboard PCBA undergoes 100% functional testing with the FCT fixture, including full key trigger testing, LED lighting effect inspection, communication verification, and other functional checks.
We support pre-flashing of mainstream open-source firmware such as QMK, VIA, Vial, and ZMK, including programming the keyboard firmware into the MCU on the PCBA.
At the same time, we verify that the firmware can be properly recognized and that all keys can trigger correctly. After receiving the PCBA, you can assemble and use it directly without any additional firmware programming.
If you need a customized Bluetooth/2.4G wireless keyboard PCBA, we will add dedicated wireless verification on top of the standard functional testing. We will also conduct actual power consumption measurements and RF signal strength tests, real-world usage distances and interference environments, to test the pairing stability.
Before shipment, we will complete a final quality verification for the entire batch, including visual inspection (100% inspection of PCB surfaces and silkscreen alignment, with acceptance criteria based on IPC-A-610 standards), warpage sampling inspection (internal control standard ≤0.75%), and packaging verification.
In addition, the batch test report will also be packaged together with the shipment.

End-to-End Turnkey Solutions
We will first sign an NDA with you. Then our engineer will evaluate the feasibility and find the potential design risks.
Based on your Gerber files and BOM, we provide a free manufacturability review report and a detailed quotation for your keyboard PCB.
We source BOM components through global authorized channels, perform strict incoming inspection and classification, and then start bare PCB manufacturing.
After that, the bare PCBs enter the SMT/DIP production lines and undergo a series of tests.
After SMT assembly is completed, we perform optical inspection and functional testing. Then, we will apply ESD protection and moisture-proof packaging before shipment.
The bare PCB prototypes’ MOQ is 5 pieces. For our PCBA services, the MOQ for small-batch trial production is usually 100 sets (depending on BOM complexity). For mass production, we don’t limit the upper amount, and we will flexibly arrange the production based on your order.
Yes. We support printing your brand logo, model number, revision number, or custom graphics on the PCB solder mask layer. You only need to add the silkscreen layer in the Gerber files or provide a vector graphic file.
Yes. You can specify the component brand, part number, and even lot number in the BOM. We source the components through authorized distributors worldwide and Tier-1 distributors in China to ensure genuine component supply.
If a component shortage occurs, our team will notify you and suggest suitable replacements, including specification comparisons and test results for evaluation, or you can also specify the replacement part numbers; we will proceed with procurement according to the new BOM.
Yes. We support customer-supplied materials for PCBA assembly. You can ship the components to our factory, such as switch sockets, LEDs, and MCUs. Then we will perform IQC inspection to verify their appearance, quantity, and brand consistency.
But please note that, under the customer-supplied material model, the functional defects and batch consistency risks of the components are your responsibility.
PCB prototypes can be shipped within 24 hours at the earliest. For PCBA prototypes, the typical lead time is 5–7 working days (when all BOM components are available and no substitutions are required). We will confirm the exact delivery schedule with you after the DFM review.
Small-batch PCBA pilot production (100–500 units) will usually be completed within 10–15 working days after all the materials are ready. The lead time may vary slightly depending on actual production conditions. We will give you a confirmed production schedule during the quotation stage.
If there are any quality defects after you receive the products, our engineering team will respond and analyze them as quickly as possible.
Our acceptance criteria are based on IPC-A-610 Class 2/3 standards. If the issue can be confirmed to be caused by our manufacturing defects, we will provide rework or a refund without conditions. When there is any dispute regarding the evaluation results, the products can be submitted to a third-party laboratory for arbitration.
For bare PCBs, we use vacuum-sealed aluminum foil moisture-proof packaging and an outer layer of anti-static bubble wrap. For the finished PCBAs, we will first place them in anti-static shielding bags, then secure them inside customized EPE foam or anti-static foam trays.
Also, if any physical damage occurs during transportation, we will take on the compensation.
