Metal Core PCB
Why Choose Metal Core for PCB Material?
You can rest assured to buy Jiubao 1 Layer Aluminum Pcb from our factory. The metal core printed circuit board is a composite printed circuit board composed of a metal substrate, an insulating medium layer and a circuit copper layer. The metal matrix is usually aluminum, iron, copper, invar copper, tungsten-molybdenum alloy, etc. The heat dissipation of the metal substrate is higher than that of the copper clad laminate. The heat dissipation of the metal substrate is related to the density and thermal conductivity of its insulating layer. The thinner the insulating layer, the higher the thermal conductivity. The insulating layer is usually modified epoxy resin, polyphenylene ether, polyimide, etc. The thickness of the insulating layer is 50 μm-200 μm. The circuit layers consist of copper layers. The thickness of the metal plate is 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 3.0mm and 5.0mm. Like rigid-flex printed circuit boards, metal-based printed circuit boards can be divided into single-sided, double-sided and multi-layered, and are a special variety of printed circuit boards. Metal PCB is also known as metal core PCB, MCPCB, IMS (insulated metal substrate), metal clad PCB.

A metal PCB consists of a layer of copper foil, a dielectric layer, and a metal layer.
· Circuit copper layer: The copper layer used is thicker than normal CCL (1oz-10oz). Thicker copper layers mean greater current carrying capacity.
· Dielectric layer: The dielectric layer is a thermally conductive layer with a thickness of about 50μm to 200μm. It has low thermal resistance, heat transfer and insulation.
· Metal layer: The third layer is a metal layer, consisting of aluminum or copper, which has high thermal conductivity.
1-layer Aluminum Pcb
1-layer aluminum substrate product introduction:
The 1-layer aluminum pcb is an aluminum pcb board; the 1-layer aluminum pcb is divided into three layers: aluminum, insulating layer, and copper. Aluminum is for heat dissipation, the insulating layer is for heat transfer and insulation, and copper is for electrical conductivity. 1-layer aluminum pcb generally have printed circuits on one side and smooth wireless circuits on the other side. The most common aluminum pcb on the market are 1-layer aluminum pcb. The upper side is the circuit, and the lower side is connected to the shell or thermal adhesive for heat dissipation. The 1-layer aluminum pcb replaces the previous FR4 and PCB glass fiber board, which is strong and high-profile, has good heat dissipation, is not easy to break, and has good product structure flexibility. Jiubao Technology is a manufacturer with metal core PCB manufacturing process, a full set of high-end precision equipment 7S production workshop from material feeding to finished product packaging, employs high-quality elite team management, and has a strong professional team engaged in circuit board production , There are many outstanding engineers and professional managers. It is a professional aluminum pcb manufacturer with large scale, complete equipment, strict management and superior quality.
The 1-layer aluminum pcb is an aluminum-based copper clad laminate (a copper clad laminate is a substrate of a PCB). Aluminum PCBs are actually very similar to FR4 PCBs

Heat dissipation: Aluminum PCB's performance in heat dissipation is quite good compared to ordinary FR4 PCB. For example, a 1.5mm thick FR4 PCB has a thermal resistance of 20-22 degrees per watt, while a 1.5mm thick aluminum PCB has a thermal resistance of 1-2 degrees per watt.
1-layer Aluminum Pcb Product Manufacturing and Production Process Manufacturing Instructions:
Thermal Expansion: Each substance has its own coefficient of thermal expansion. Aluminum (22ppm/C) and copper (18ppm/C) have very close CTEs. Since the aluminum PCB works well in terms of heat dissipation, there will be no serious expansion or contraction issues. Aluminum PCBs work great, durable and reliable.
Dimensional stability: Aluminum PCBs show dimensional stability and stable dimensions. For example, when they are heated from 30-140 degrees, their dimensions only change by 2.5%-3.0%.
· Others: Aluminum pcb can be used in surface mount technology for power devices. Aluminum PCB can be effectively used in circuit design due to its performance in terms of thermal expansion of circuit design. Aluminum PCBs help extend product shelf life and product power density. Aluminum PCBs are also very reliable. Aluminum PCBs can help reduce the overall size of the product and are also a cheaper option. Aluminum PCBs exhibit electromagnetic shielding and high dielectric strength.
