Description

[technical field]

[0001] The invention relates to the field of printed circuit boards, in particular to a method for embedding a printed circuit board and the printed circuit board. [Background technique]

[0002] As the PCB (Printed Circuit Board) realizes more and more functions, there are more and more corresponding electronic devices on the PCB, and the remaining space available on the PCB is getting smaller and smaller. If new functions are to be added on the PCB, it is often given up due to the space limitation on the PCB, or after adding new functions on the PCB, the volume of the PCB is too large, which is not conducive to product assembly.

[0003] Today's electronic products are developing in the direction of miniaturization, and the same requirements are also required for PCBs, that is, to increase the density of the external electronic components of the PCB, or to reduce the number of electronic components installed on the PCB, so as to obtain a highly integrated...
