Single Layer PCB Material
We offer a wide range of single layer PCB materials to support different applications, from low-cost consumer electronics to high-frequency and high-power systems.
FR-4
FR-4 is the most widely used material for single layer PCBs due to its excellent balance of cost, electrical insulation, and mechanical strength.
It is a composite material made of woven fiberglass cloth and epoxy resin, providing a rigid and stable structure.
- Good electrical insulation performance
- High mechanical strength and rigidity

Material Selection
We will choose the right substrate material based on application requirements.

Copper Cladding
A thin layer of copper is laminated onto the base material to form the conductive surface. This copper layer will later be etched to create the circuit pattern.
Imaging
A photoresist layer is applied to the copper surface. The PCB design pattern is then transferred onto the board using UV exposure through a photomask.
Etching
After imaging, the board undergoes a chemical etching process to remove unwanted copper. Only the copper protected by the photoresist remains, forming the desired circuit traces.
Drilling
If the design requires through-hole components, holes are drilled using high-precision CNC drilling machines.
Solder Mask
A solder mask layer is applied to protect the copper traces from oxidation and prevent solder bridging during assembly.
Surface Finish
A surface finish is applied to exposed copper pads to improve solderability and prevent oxidation.
- HASL
- Lead-free HASL
- ENIG
- OSP
- Immersion silver
Silkscreen Printing
Silkscreen printing adds markings
Electrical Testing
Each PCB undergoes electrical testing to verify that all circuits function correctly.
