LTCC, translated into Chinese, refers to low-temperature co firing ceramics. The reason for low-temperature co firing is to lay silver wires on the ceramics, as the maximum sintering temperature for silver is 920 ℃. If silver lines are printed inside and on the surface of ceramics, and burned together with ceramics, it is called a ceramic substrate. Ceramic substrates with dual functions of heat dissipation and lead wires on the upper and lower surfaces of LED lights are ceramic substrates. Of course, there are also those that are not used as substrates by firing, such as those used for coils by Magming Technology. Currently, most circuit boards are PCB boards, which are organic materials.

Nowadays, in order to achieve greater integration, people hope to integrate many capacitors, resistors, inductors, etc. into PCB boards. Most of these are ceramic materials that require high-temperature sintering, and PCBs cannot be fired. Therefore, people think of ceramic boards with good insulation performance and the ability to sinter at high temperatures. At the same time, the dielectric constant of ceramics is adjustable.

PCBA is the abbreviation for Printed Circuit Board+Assembly in English, which refers to the entire process of PCB blank board being SMT mounted and then DIP plug-in, abbreviated as PCBA. This is a commonly used writing method in China, while the standard writing method in Europe and America is PCB'A, with the addition of "'", which is known as the official idiomatic expression.
