For industrial panels, smart terminals, digital signage, and human-machine interface (HMI) products, an advanced MCU control board solution can enhance product stability, and minimize development risk.

EFPCB offers the whole service for design assistance, **PCB manufacturing, components procurement, SMT assembly, testing and customization. Leveraging on engineering expertise and mature manufacturing capabilities, EFPCB enables customers to realize a concept into a production-worthy [MCU control board solution](https://www.efpcb.com/products/pcb-solution/iot-pcb-design/rockchip-rk3128-display-mcu-control-board-solution/)** with reliable performance and scalable delivery.

Why Rockchip RK3128 is suitable for display application

The RK3128 platform strikes a reasonable balance among processing power, multimedia capabilities and cost efficiency. Based on Rockchip, the design can realize display control, user interface, data communication and system management in one small board. This is ideal for products need steady running while without too complicated hardware. Good adapter for PC and other devices. The platform can support smooth operation of UI, media play, touch control and peripheral expansion. These are the key feature for retail, automation, education, healthcare and smart home device.

For hardware teams, Rockchip provides the mature ecosystem to speed up the software customization. Developers can more easily enhance the booting time, display parameter, touch response, and communication function. This kind of maturity is particularly beneficial for custom designs, in which multiple customers might have varying needs in terms of display size, interface layout or function modules.

Focused Design of MCU Control Board

A professional MCU control board solution starts from the clear what is the application. For both, the engineers have to consider the display resolution, memory size, storage layout, power input, communications interface, operating temperature and mechanical limitation. Every decision you make in your design affects reliability and user’s experience.

The PCB layout is considered as the key stages. High-speed signal routing, grounding scheme, impedance control, and power supply distribution are required to be well-handled. Bad layouts may cause flickers on the screen, unstable touches, errors in data transferring, or worse, cause electromagnetic interference. EFPCB is highly focused on these factors in schematic review and PCB layout optimization. Power management is another important issue. Display Control Boards usually work non-stop, thus the power supply need offer constant voltage stable output, high efficiency DC/DC conversion and over voltage or under voltage protection. DC/AC inverter is also used. Thermal performance must also be considered. Advanced placement of components and design of copper cladding can also assist in spreading heat and extend service life.

Firmware and hardware should be designed in tandem. A good MCU control board solution need to have smooth boot up, precise display timing, stable touch calibration and stable peripheral communication. When hardware development and software porting are performed in parallel, the end product is easier to test, service and upgrade.

EFPCB Design and Manufacturing Advantages

EFPCB customized display control boards based on Rockchip RK3128 for high volume production with great stability and design cost efficiency. The firm can assist clients through early design evaluation and onto volume manufacturing, bridging the communication gap between engineering and manufacturing teams.

At the prototype level, EFPCB assists in confirming circuit feasibility, component sourcing, PCB stack-up and process requirements for assembly. This pre-review reduces the probability of redesign and increases the project efficiency. Since Rockchip reference material are quite popular, EFPCB has the advantage to leverage that proven platform knowledge base with a customer specific requirements to design a chip solution that is practical and dependable.

Process Control

EFPCB implements strict process control during production. PCB production, solder paste printing, component mounting, reflow soldering, inspection and functional testing are controlled under established quality criteria. AOI and electrical testing also aid in capturing potential defects pre-shipment. For the MCU control board solution, EFPCB can perform display output test, interface testing, power stability test, and aging test as per project demands.

Another major benefit is the ability to customize. Customers can have special requirements on LCD connectors, touch panel interfaces, UART, USB, wireless modules, audio circuit or even customized size for the board. EFPCB can make the design modification while keep the production feasibility. This is a huge benefit for OEM and ODM clients who are looking to separate themselves through unique products tailored to specific markets.
