PCBs in electronic technology products are an integral part of electronic information equipment in modern businesses. Copper thickness is a very important factor in the development of PCB manufacturing. The correct copper thickness we can get to ensure the quality and performance of the circuit board, but also affect the reliability and stability of e-commerce products.
Typical copper thicknesses are 17.5 microns (0.5 ounces), 35 microns (1 ounce) and 70 microns (2 ounces).
The thickness of the copper determines the conductivity of the board.multilayer pcb fabrication Copper is an excellent conductive material and its thickness directly affects the conductivity of the circuit board. If the copper layer is too thin, the conductivity may be reduced, resulting in signal transmission degradation or current instability. But if the copper layer is too thick, although the conductivity will be good, but will increase the cost and weight of the circuit board. Moreover, too thick a copper layer will easily lead to severe runout, and too thin a dielectric layer will increase the difficulty of circuit processing. Therefore, it is generally not recommended to make the copper thickness of 2oz. In PCB manufacturing, you need to select the appropriate copper thickness according to the design requirements of the circuit board and the actual application, in order to achieve the best conductive effect.
Secondly, the thickness of copper has an important impact on the thermal performance of the circuit board. With the growing power of modern electronic equipment, the heat generated in the process of its work is also more and more.1 oz vs 2 oz Copper Good thermal performance can ensure that the temperature of electronic components in the working process is controlled within safe limits. The thickness of the copper layer, as the thermal conductive layer of the circuit board, determines its heat dissipation effect. If the copper layer is too thin, it may lead to heat can not be effectively conducted and distributed, increasing the risk of component overheating.
Therefore, the copper thickness of the PCB should not be too thin. In the process of PCB design, we can also lay copper in the blank area to assist PCB heat dissipation. In PCB manufacturing, choosing the right copper thickness can ensure that the circuit board has good heat dissipation performance to ensure the safe operation of electronic components.
In addition, copper thickness is also an important factor for the reliability and stability of a circuit board. Copper layer can not only serve as a kind of conductive layer and thermal conductive layer, but also the support and connection layer of the circuit board. Appropriate copper thickness can be developed to provide sufficient mechanical design strength to prevent the circuit board from bending, breaking, or soldering during the use of the management process. At the same time, the appropriate copper thickness data can be obtained to ensure the quality of the circuit board and other components of the soldering work, reduce the risk of soldering technology defects and failures. Therefore, in PCB manufacturing, choose their own appropriate copper thickness in general can effectively improve the reliability and stability of the circuit board, to extend the service life of electronic information products.
In summary, the importance of copper thickness in PCB manufacturing should not be ignored. The correct thickness of copper cladding can ensure the conductivity, heat dissipation, reliability and stability of the circuit board.
In the actual manufacturing process, you need to select the appropriate copper thickness according to the circuit board design requirements, functional requirements and cost control to ensure the quality and performance of electronic products. Only in this way can we produce high-quality PCBs to meet the requirements of modern electronic equipment for high performance and high reliability.
