Why is Aluminium used in circuit boards?
Advantages of aluminum substrate PCB
a. The heat dissipation is significantly better than the standard FR-4 structure.
b. The dielectric used is usually 5 to 10 times the thermal conductivity of traditional epoxy glass and 1/10 the thickness.
c. The heat transfer index is more effective than traditional rigid PCB.
metal base printed board aluminum substrate PCB
Aluminum substrates are widely used. General audio equipment, power equipment, and communication electronic equipment include aluminum-based Microwave radio frequency board, Microwave radio frequency board, office automation equipment, automobiles, computers and power modules.
There are three differences between fiberglass board and aluminum substrate PCB
A. Price
The important part of LED fluorescent tube is: custom circuit board cost manufacturing, LED chip and driving power supply. Common circuit boards are divided into two types: aluminum substrates and fiberglass boards. Comparing the price of fiberglass board and aluminum substrate, the price of cheap custom pcb fabrication fiberglass board will be much cheaper, but the performance of aluminum substrate will be better than that of fiberglass board.
B. Technical aspects
According to different materials and manufacturing processes, fiberglass boards can be divided into three types: double-sided copper foil fiberglass boards, perforated copper foil fiberglass boards and single-sided copper foil fiberglass boards.
c. Performance
As we all know, aluminum substrate has good heat dissipation performance, and its heat dissipation performance is much better than fiberglass board. Because the aluminum substrate has good thermal conductivity, the aluminum substrate plays an important role in the field of LED lamps.
