Aluminum Entry Drilling Sheet V PCB Entry Sheet
PCB entry sheet, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is to greatly reduce wiring and assembly errors, and improve the level of automation.
Aluminum drilling entry sheet is a aluminum base sheet with a cover of copper. Generally, it is made up of a three-layer structure, which is a circuit layer (copper foil), an insulating layer, and a metal base layer(aluminum sheet). It is commonly used in LED lighting products.
PCB entry sheet is a big kind covering several varieties such as aluminum PCB sheet, copper PCB sheet, glass fiber circuit boards,etc. In most cases, PCB entry sheet is a copper substrate, which is also divided into a single panel and a double panel.
The main material of aluminum PCB sheet is a kind of aluminum entry sheet while that of copper PCB board is copper sheet. The price of copper PCB board is a little expensive.
Due to the difference between the performance of copper and aluminum and the corresponding PCB processability, copper substrates have higher performance advantages than aluminum substrates.
FR-4 glass fiber circuit board is a traditional electronic product circuit board. Due to its good insulation, corrosion resistance, pressure resistance, multi-layer printing and other characteristics, it is widely used in communications, automotive, medical, industrial control, security and other fields. Its thermal conductivity is much lower than aluminum PCB sheet.
