The Ferrum Core PCB is a metal heat sink substrate applied to high-end motors, high-end products and motors. It is widely used in the market. The hardness of the Ferrum Core PCB is much larger than that of the Aluminium Core PCB. It is difficult for general manufacturers to master. The technology, cost cost and scrap rate are relatively high.
The Ferrum Core PCB can be divided into single-sided Aluminium Core PCB (green Ferrum Core PCB), a double-sided Ferrum Core PCB, and the thickness is generally between 1 mm and 6 mm. The Ferrum Core PCB has a circuit layer: a copper-clad board equivalent to a common PCB, and the thickness of the copper foil of the line is 1 oz to 8 oz. between.

The The Ferrum Core PCB process is generally: 1 grinding plate → 2 washing → 3 passivation → 4 washing × 3 → 5 drying → 6 drying, grinding plate: only grinding the iron surface, grinding the plate according to FR4 parameters. The first board is required to check that the line is not scratched, the tin surface is black, and the wear marks are even.
1 High mechanical strength, good toughness, good machinability and the ability to install heavy components on its surface.
2 Non-wiring parts can be processed in various shapes to facilitate the mounting of the substrate.
3 Silicon steel plate also has ferromagnetism and can be applied to micro motors in VTR, FDD, etc. The thickness of the iron plate is 0.5mm, 1.0mm, etc., and the thickness of the copper foil is 1OZ, 2OZ, 3OZ, 4OZ, and the like.
Ferrum Core PCB has superior anti-electromagnetic interference, shielding performance is optimal, but heat dissipation is poor, and the price is cheap. Uses: various high-performance floppy disk drives, computer brushless DC motors, fully automatic camera motors and some military cutting-edge technology products .
The hardness of the Ferrum Core PCB is much larger than that of the aluminum Core PCB. The technology is difficult for the manufacturers to master, and the cost and scrap rate are relatively high.
