Embodiment Construction
[0033] In order to make those familiar with the art understand the purpose, characteristics and effects of the present invention, the following specific examples are used to illustrate this creation in detail, as follows:
[0034] Please refer to figure 2 , illustrating a schematic structural view of the high heat dissipation circuit board of the present invention, the high heat dissipation circuit board 2 includes: at least one metal substrate 21; an insulating layer 23, the insulating layer 23 is an insulating surface with thermal conductivity, to implant conductive lines; And a buffer layer 22, the buffer layer 22 is interposed between the metal substrate 21 and the insulating layer 23, so as to improve the joint adhesion between the metal substrate 21 and the insulating layer 23, and reduce the peeling or peeling of the plating due to thermal stress. phenomenon of rupture.
[0035] Please refer to image 3 , illustrating the flow chart of the manufacturing method of the...
