Because of characteristics of the good heat dissipation, the aluminum plate, which is kind of direct drive cooling products develops very fast in the PCB industry. With the high heat resistance voltage and low thermal resistance, the products combined with aluminum plate has much longer life and are welcomed by the LED industry.
And with the rapid development of technology, quickly improved aluminum PCB related equipments, the aluminum PCBs' price has become more and more affordable for most clients. So if you have purchase requirements for aluminum, please feel free to contact PCBA STORE here.
The aluminum substrate is a metal coated copper plate with good heat dissipation function. The general single panel consists of three layers, which are the circuit layer (copper foil), insulating layer and metal base. For high-end usage, there are also design for double layers, which are consisted of circuit layer, insulation layer, aluminum base, insulation layer and circuit layer. Very few applications are multilayer, which can be made from ordinary multilayer plate and insulation layer, aluminum base. And more and more start to use aluminum PCB in their business.
Different materials in PCB creations have quite different usage. Printed circuit boards with aluminum cores (known as aluminum PCBs) have different properties from standard printed cicruit boards (without metal substrates). These two widely used printed circuit board type are very popular in consumer electronic area. But if you want to know whether an aluminum pcb is better than standard printed circuit board or not, it will much depends on your actual intended application.
Because of the excellent thermally conductive features, the aluminum PCBs could easily keep heat away from vital components to make sure minimal circuit damage.
The high heat tolerance could let it easily deals with high density circuits and larger power levels
The substrated of aluminum alloys could lower the breakage risk of the aluminum PCBs
Aluminum PCBs are quite environmental friendly
Aluminum PCBs are very strong but lightweight metal compared with base materials
Reasonable PCB cost
Compared with standard PCBs, it has higher price
If you are not invovled with high temperatures, aluminum won't be that useful
The aluminum PCBs can not withstand too much vibration stress
Through-hole aluminum PCBs
Flexbile aluminum PCBs
Hybrid aluminum PCBs
Generally speaking, if the printed circuit boards should be exposed to large mechanical loads, or a high level of dimensional stability is required, or we must pass the high temperatures from power components or LED's, then aluminum core PCB or IMS (Insulated Metallic Substrate) circuit boards could be an excellent alternative to those standard printed circuit boards.
The thermal conductivity assisted by the aluminium core in the printed circuit boards makes the aluminum PCB has much higher packing densities, longer operating times, and improved security against possible failure, such as for LED technology and for high power transistors.
There are a few additional applications could use such aluminum PCB technology, such as the high current application, power LED, SMD and power circuit boards. The high thermal conductivity allows the quick and effective transfer of the heat produced in the applications.
Audio equipment: Input, output amplifier, balance amplifier, audio amplifier, preamplifier, power amplifier, etc.
