Supplier chain: Source high-quality components that meet industry standards and specifications from reputable or big agent suppliers for relays, capacitors, and resistors and so on ,to ensure quality be durability and stability.

Temperature Resistance: Given the nature of oven applications, control boards must withstand high temperatures without compromising functionality. Choose materials and components that are rated for elevated temperatures to prevent overheating and ensure long-term reliability.

Electromagnetic Interference (EMI) Shielding: Incorporate EMI shielding techniques to protect the control board from electromagnetic interference generated by other electronic devices or nearby electrical circuits. Proper shielding helps maintain signal integrity and prevents malfunctions due to external interference.

Safety Features: Implement safety features such as overcurrent protection, overvoltage protection, and short-circuit protection to safeguard both the control board and the oven from potential electrical hazards. Compliance with safety standards and regulations is essential to ensure product safety and reliability.

User Interface Design: Design an intuitive user interface with clear labeling, responsive buttons, and informative displays to enhance user experience and usability. Consider ergonomic factors such as button placement and size to facilitate user interaction and minimize errors during operation.

Reliability Testing: Rigorous reliability testing is carried out during the manufacturing process to identify and address any potential defects or weaknesses in the control board design. Testing procedures may include ,temperature cycling, humidity testing, vibration testing, and accelerated aging tests to simulate real-world operating conditions and ensure robust performance.

Quality Control: By 6 Sigma to control every production process to ensure every process  be controlled and qualified.
