With the continuous development of the electronics industry, a variety of electronic products continue to emerge, among which aluminum substrates and PCB boards are two very common substrates. Not only do they play an important role in electronic products, but they are also an essential part of the electronic assembly process. However, what is unexpected is that these two substrates, which look very similar on the surface, actually have many obvious differences. This article will introduce the differences between these two substrates in detail in terms of technology, process, and usage. 

First of all, from a technical point of view, aluminum substrates are made of aluminum-based materials, and their main features are good thermal conductivity and oxidation resistance, which are suitable for high-power electronic equipment. The PCB board refers to the printed circuit board, which is to realize electronic assembly by covering a layer of conductive metal on one or more layers of insulating substrates, and forming corresponding circuit patterns on its surface. It is suitable for small size and light weight of electronic products. Quantification and occasions with high reliability requirements.

Secondly, from a technological point of view, the manufacturing process of aluminum substrates is relatively simple, and most of them use drilling technology for processing, so their manufacturing costs are relatively low. However, PCB boards require complex processes such as drawing circuit patterns and forming conductive layers on the substrate through chemical reactions or photolithography techniques, so the production cost is relatively high. 

Finally, from the perspective of use, aluminum substrates are suitable for high-power heating devices, photoelectric modules, mechanical devices, automotive electronics and other fields, and their main advantages are high reliability and good heat dissipation. The PCB board is suitable for computer peripherals, communication equipment, notebook computers, consumer electronics and other fields. Its main advantages are high manufacturing precision, high space utilization, and unlimited shapes. It can be said that aluminum substrates and PCB boards have their own unique advantages in different scenarios. To sum up, although the surface of the aluminum substrate and the PCB board look very similar, there are essential differences between them. Knowing these differences can help us better choose the substrate suitable for our products, thereby improving the performance, stability and reliability of our products.
