What are the requirements of the circuit board plate
PCB board is an important basic material in the electronics industry, and its quality directly affects the performance and life of electronic products.
Board Board Requirements
Introduction to 1.
PCB board is an important basic material in the electronics industry, and its quality directly affects the performance and life of electronic products. Therefore, a series of requirements for the circuit board plate is the key to ensure product quality.
Main 2. Requirements
1. Material properties:
(1) Good conductivity: to ensure circuit conduction, reduce resistance.
(2) excellent insulation performance: to ensure that the circuit is not short-circuited.
(3) high thermal stability: in high temperature environment to maintain stable performance.
(4) Good processing performance: it is convenient for the production and processing of circuit boards.
2. Dimensional accuracy:
The dimensional accuracy of the circuit board plate is very important to its application. Dimensions such as length, width and thickness must be strictly controlled to ensure the accuracy of matching with other components.
3. Surface quality:
(1) High flatness: Ensure the reliability of circuit board welding and the stability of circuit conduction.
(2) No defects: such as cracks, bubbles, impurities, etc., to ensure the performance and service life of the circuit board.
(3) Good surface treatment: improve the solderability and reliability of the circuit board.
4. Environmental requirements:
(1) Use environmentally friendly materials: such as flame retardant, halogen-free, etc., in line with environmental standards.
(2) Low emission of harmful substances: in the process of production and use, reduce the impact on the environment.
3. special length requirements (taking 600mm as an example)
For circuit board plates with a length of 600mm, in addition to the above general requirements, special attention should be paid to the following points:
1. Length accuracy control: Ensure that the length is accurate to the millimeter level to meet the needs of precision electronic products.
2. Sheet stability: in transport and
