Metal core printed circuit boards are PCBs that use a base material with high thermal conductivity. This base is used to draw heat away from the components and dissipate it more rapidly. A metal core printed circuit board (MCPCB) is a printed circuit board made from a heat conductive metal base material. The most common MCPCB metals are aluminum and copper, although other materials are available such as iron, steel or silver. These boards can be made from either rigid or flexible substrates.
The most common applications for MCPCBs include power semiconductors, high power LEDs, and high current switching power supplies.
Different uses of metal core printed circuit board
MCPCBs are created by bonding a metal base
material, typically aluminum or copper, to a standard FR-4 (flame retardant 4)
PCB. The metal used for the core material is often an alloy such as aluminum
nitride, aluminum oxide or diamond.
They are used in applications that require
a high level of heat dissipation. They have three layers: a dielectric
substrate, metal base and metal heat spreader. They are usually made with an
LED and a thermal management system to prevent overheating.
They are commonly used in LEDs, power
supplies and motor drives. They are very useful in applications where large
amounts of thermal management are required. They consist of a dielectric layer
that is placed between the metal base layer and the copper circuitry.
The dielectric layer can be made of either
ceramic or any other kind of material that has a low thermal conductivity. In
most cases, however, aluminum or copper is used as the composite base. The
metal base is usually only 0.05-0.25 mm thick and the dielectric layer is about
1-5 mm thick. The thickness of the copper circuitry is 0.035-0.250 mm.
4 important factors to choose an MCPCB company
To choose the metal core printed circuit board providing company, you must
consider some factors such as:
1. The quality of products.
2. The service provided by them.
3. Their price policy and other factors
that may affect your decision to choose them or not.
4. Their after-sales support.
Final Words
The metal core PCB is one of the most
advanced types of PCBs. It is a circuit board with a metal core that can be
used in high-frequency circuits and high-speed data transmission. It is usually
made with copper, nickel or other conductive materials. It has many advantages including
improved signal integrity, low electromagnetic interference (EMI) and lower
cost than other substrates.
The metal
core printed circuit board was first developed by IBM in 1968 for use as a
substrate for printed circuit boards. It was used as a substrate for printed
circuit boards because it provided better electrical performance than other
substrates such as FR4 or epoxy glass laminate.
There are several different types of PCB
companies available in the market. You should pick a reputed one. You need to
find out the standard cost by analyzing the market and choosing the one that
fulfills your PCB needs at the best prices.
