What is a microcavity substrate?

Micro Cavity Substrates (MCS) are a special type of printed circuit board designed to provide an ideal mounting environment and support structure for micro electronic components. Compared with traditional printed circuit boards (PCBs), microcavity substrates have higher density, more precise layout, and better heat dissipation performance. In microcavity substrates, microscopic components such as microchips, sensors, and transistors are housed within carefully designed microscopic grooves, or “cavities,” to minimize the overall size of the circuit board and improve the performance of the electronic device.

The role of the microcavity substrate is not only reflected in the installation space it provides for micro components, but also in its optimized circuit layout and thermal management capabilities. Through precisely designed microcavity structures, interference and signal loss between circuits can be minimized, thereby improving device stability and performance. In addition, the microcavity substrate can effectively disperse and conduct the heat generated by the components, preventing the device from overheating and extending its service life.

In modern electronic devices, microcavity substrates are widely used in various fields, including communications, medical, automotive, aerospace, etc. For example, in smartphones, microcavity substrates can accommodate multiple sensors and chips, enabling more functions in a smaller space.
