1、 Copper substrate PCB
Introduction to copper substrate PCB products:
Copper core printed circuit board, as the name suggests, is a printed circuit board made by pressing copper core metal, insulation layer, and metal copper foil, which is also known as copper circuit board or copper substrate PCB. Copper substrate PCB has special thermal conductivity and excellent heat dissipation. According to the structure of stacked copper cores, Jiubao Technology provides copper substrates for single-sided MCPCBs and copper substrates for two-layer MCPCBs. For the copper substrate PCB of a two-layer MCPCB, it is divided into a copper metal core in the middle of the circuit layer and a copper metal core at the bottom of the circuit layer.
Jiubao Technology is now introducing a single-sided copper substrate PCB. The single-sided copper substrate PCB is divided into three layers (copper foil, insulation layer, and C1100 red copper). C1100 red copper has the effect of heat dissipation, insulation layer has the effect of heat transfer and insulation, and copper foil has the effect of conductivity! After the copper foil is etched with photoresist, there are various lines left, which we call circuits. These circuits serve as wiring for the circuit schematic. The main function of the circuit is to connect the solder pins of LED beads, IC drivers, and other components together. The two copper foils that are welded together with the components are called pads (PADs). The thermal insulation layer is the core technology of single-sided copper substrate PCB. The composition of the thermal insulation layer is mainly composed of aluminum oxide and silicon powder, and a polymer filled with epoxy resin, with low thermal resistance and excellent viscoelastic performance. Single sided copper substrate PCB is generally relatively simple, with one side having wires and the other side being smooth copper without wires.
Single sided copper substrate PCB is a type of metal substrate with higher cost, and many fields require the use of single sided copper substrate PCB. Single sided copper substrate PCB has good heat dissipation, fast heat dissipation, durability, and is not easy to break, with good flexibility. The thermal conductivity of single sided copper substrate PCB is better than that of single sided aluminum substrate PCB and single sided iron substrate PCB, so the price of single sided copper substrate PCB is also the most expensive among metal circuit boards. Single sided copper substrate products mainly include car front headlight panels, UV lights, flashlight panels, lighting fixtures, motorcycle light panels, advertising screen light panels, stage light panels, and so on.
The types of single-sided copper substrate PCBs are: ordinary single-sided copper substrate PCBs, single-sided thermoelectric separation copper substrate PCBs, single-sided insulated hole copper substrate PCBs, and single-sided electroplated hole copper substrate PCBs.
