- Classified by number of layer
- Single-layer PCB
A single-sided LED PCB has only one layer of conductive lines, which are made of copper foil. This kind of circuit board is suitable for simple electronic products and has a low cost.
- Double-sided LED PCB circuit board
A double-sided LED PCB circuit board adds a conductive layer to the single-sided PCB, which can be wired on both sides.
- Multilayer LED PCB circuit board
Multilayer LED PCB circuit boards consist of multiple layers of substrates and conductive layers. It has a higher wiring density, better impedance control, and a better electromagnetic shielding effect.
- Classified by materials
- Regular FR4 board
Conventional FR4 boards are made of FR4 materials, which have a lower cost and good mechanical strength and heat resistance.
- High-frequency board
The high-frequency board is made of special materials, has a high dielectric constant and loss, and has good electrical performance stability.
- metal substrate
Metal substrate is a special material that uses metals such as copper and aluminum as substrates for PCB manufacturing. Due to its excellent heat dissipation properties.
