Abstract

An assembly method and device for a circuit structural member, and a circuit structural member. The assembly method comprises: measuring a depth and path of a channel between at least one chip and a printed circuit board (PCB), the at least one chip being arranged on the PCB; determining a thickness and path of a heat dissipation reinforcement material according to the depth and path of the channel between the at least one chip and the PCB and a predetermined heat dissipation parameter, so as to configure a dispensing parameter and a dispensing path; coating the heat dissipation reinforcement material in the channel between the at least one chip and the PCB according to the dispensing parameter and dispensing path; and heating the heat dissipation reinforcement material to a first predetermined temperature, such that the heat dissipation reinforcement material permeates into the chip and the PCB.

Claims (24)
