Description

technical field [0001] The invention relates to the technical field of PCB processing, in particular to a processing method for an organic optical waveguide embedded PCB. Background technique [0002] The internal signal transmission speed and bandwidth of the computing system have lagged behind the chip processing technology. The connection between components and circuit boards, and the transmission of signals in PCB (Printed circuit board, printed circuit board) boards have become bottlenecks that limit the continuous expansion of bandwidth. Factors: The traditional electrical interconnection is increasingly difficult to meet the needs of high-speed signal development due to the insurmountable theoretical upper limit of crosstalk, noise, and loss. [0003] Optical interconnection technology has huge advantages in bandwidth-transmission distance that cannot be compared with electrical interconnection: large bandwidth, high interconnection density, low power consumption, str...
