Difference circuit boards have difference structures.
Even the most simple circuit boards, also have very complex structures.
Take it easy, Jim will introduce the common structure of LED Aluminum PCB in this post.
The Structure of LED Aluminum PCB
Aluminum clad circuit board material is a metal, copper foil, thermal insulation layer and the metal substrate composition, its structure is divided into three layers:
Circuit layer of LED Aluminum PCB
Also called line layer, if you review the gerber file of LED Aluminum PCB, you will find all circuit diagram like lines.
The equivalent of the common PCB laminates, foil thickness loz line to 10oz.
Dielectric layer of LED Aluminum PCB
Also called insulation layer.
Insulation layer is a layer of thermal insulation materials with low thermal resistance.
Base layer of LED Aluminum PCB
A metal substrate, usually aluminum or copper can be selected.
LED Aluminum PCB and traditional epoxy glass cloth laminated panels.
