With the development of high technology, people need electronic products with high performance, small volume and many functions. Therefore, the PCB manufacturing is also developed into the direction of being lighter, thinner, shorter and smaller with limited space, more functions, greater wiring density and smaller aperture. From 1995 to 2005, the minimum pore size of mechanical drilling capacity decreased from 0.4mm to 0.2mm and even smaller. The size of metallized pore is also getting smaller and smaller. The quality of metallized holes depending on the interconnection between each layer is directly related to the reliability of PCB.
The double-sided ceramic PCB board is an important PCB board in the circuit board. There are double-sided ceramic PCB board of PCB metal base, Hi-Tg heavy copper foil circuit board, flat & winding double-sided circuit board, high-frequency ceramic PCB, high-frequency double-sided circuit board of hybrid dielectric base, etc. in the market. It is applicable for a wide range of high-tech industries such as telecommunications, power supply, computer, industrial control, digital products, scientific and educational instruments, medical devices, automobiles, aerospace defense, etc.
The difference between the double-sided ceramic PCB board and the single-sided ceramic PCB board is that the single-sided ceramic PCB circuit is only on one side of the ceramic PCB board, while the double-sided ceramic PCB circuit can be connected through holes in the two sides of the ceramic PCB board. The parameters and fabrication of double-sided ceramic PCB plate make it different from single-sided ceramic PCB plate. Besides the process of making, there is also a copper sinking process, which is the process of conducting the double-sided wires.

Sliton’s single & double-sided ceramic PCB, as the best ceramic PCB in China, can use laser technology to achieve the perfect combination of ceramic and copper layers with the 10% increase of overall performance. Besides single & double-sided ceramic PCB, the box dam PCB, special-shaped ceramic PCB, and multilayer ceramic PCB top the domestic market.
