YScircuit thermoelectric separation copper based PCB process steps:

1. First of all, cut the copper foil based PCB into a size that is suitable for processing.

2. Note that it needs to roughen the copper foil on the PCB surface with brushing, micro-etching and so on before squeezing film the based PCB.

3. Then, attach the dry film to the photoresist at an appropriate temperature and pressure, and it will create polymerization after being irradiated with ultraviolet light in the transparent area of the film, where the dry film will be reserved as an etching resist when developing and copper etching, however the circuit image on the film will be transferred to the dry film photoresist on the board.

4. Develop and remove the unexposed area on the film surface with an aqueous solution of sodium carbonate after peeling off the protective film on the film surface, and corrode and remove the exposed copper foil with a mixed solution of hydrochloric acid and hydrogen peroxide to form a circuit.

5.Finally, clean the dry film photoresist that has been finished with an an aqueous solution of sodium hydroxide. For six or more layers inner layer PCB, it can punch out the reference hole of the interlayer circuit with the automatic positioning punching machine.

FQA

1. What is the thickness of a metal core PCB?
The thickness of the metal core in a PCB substrate is typically 30 mil - 125 mil, but thicker and thinner boards are possible.

2. What are the advantages of metal core board?
Metal core boards transfer heat 8 to 9 times faster than FR4 PCBs.
These metal core laminates keep heat-generating components cool by dissipating heat faster.
The dielectric material is kept as thin as possible in order to create the shortest path from the heat source to the metal backplane.

3. How is a metal core PCB made?
If the board is a single-layer board with no layers transitioning back to the metal plate, the dielectric layers can be pressed and bonded to the metal plate using the standard process used with FR4 dielectrics.

4. What is a metal core PCB?
A metal core printed circuit board (MCPCB) is a printed circuit board that contains base metal materials.
The core is designed to transfer heat away from components that generate a lot of heat.
