1. Material requirements: the circuit boards should be made of fire-resistant performance materials in accordance with the relevant national standards, such as FR-4 or high TG materials, to ensure their high-temperature resistance.
2. Dimensional requirements: The dimensions of the circuit board should meet the design requirements to ensure that it can be installed in medical device equipment and meet its functionality and appearance requirements.
3. Layout: The circuit layout of the board should be reasonable to meet the performance requirements of the medical device, and avoid circuit cross-talk and noise problems.
4. Layers of circuit boards: According to the functional requirements of medical devices, the number of layers of circuit boards should be reasonably designed to ensure the stability and reliability of circuit connections.
5. Pad requirements: The pads should meet the requirements of reliable welding performance and pin connection to ensure that the electronic components can be correctly installed and connected.
6. Board surface treatment requirements: board surface treatment should be used in accordance with the relevant national standards of anti-corrosion technology, such as HASL, ENIG, etc., in order to improve the durability and reliability of the board.
7. Testing requirements: the circuit board should be subject to strict electrical performance tests and reliability tests to ensure its working stability and safety.
8. Marking requirements: the circuit board should be clearly marked with relevant information, such as manufacturer, product model, specifications, etc., to facilitate traceability and use.
It should be noted that the above requirements are only a general reference, the actual requirements also need to be based on specific medical devices and national/regional regulations and standards for specific determination.
