Rigid PCB Types

One of the advantages of rigid PCBs is their ability to work be used for various project specifications and configurations. At YiYanPCB, we offer rigid PCBs in a range of types, including:

Single-sided: Single-sided circuit boards are the original PCB. They have a single layer of conductive material, and all components are located on one side of the board. With their simple design, single-sided PCBs are fast and easy to manufacture, reducing the possibility of mistakes. This cost-effective configuration thrives in low-density designs.
Double-sided: Rather than a single conductive layer, double-sided PCBs utilize copper conductive layers on both sides. With twice the space for components, double-sided PCBs have more design options and increased circuit complexity, making them applicable for a wide range of projects.
Multilayer: This type of PCB uses three or more layers of conductive material stacked in the middle with several other layers surrounding the core. With numerous layers and an advanced curing process, multilayer boards reduce the need for interconnection wiring, save space and result in a dense and tough PCB.
Carrier board or Mechanical Spacer: When you need a rigid backer to provide support during the assembly process for very thin PCBs, some companies may opt to use a carrier board that has no conductive layers. Any circuit board that is used for mechanical operations does have any copper layers or require any electrical connections. At YiYanPCB, we can create a bare rigid PCB according to your exact specifications to support all components and equipment you intend to work with.

Material Considerations

The materials in your rigid PCB depend on the specifications of your project. With several material offerings, you can design your rigid PCB for your application.

Conductor

At YiYanPCB, we supply PCBs with specialized metal cores, such as aluminum, for high thermal conductivity that remains cost-effective. The metal core we use will depend on your specifications and conductivity needs.

Adhesives

Your adhesive will vary based on your project specs and conductor thickness. Some options are:

Epoxy.
Prepreg.
Acrylic.

Insulators

We will provide an insulator that offers strong signal transmission and safety. Possible materials include:

Coverlays, covercoats and solder mask layer.
Standard FR-4 materials.
Lead-free compatible FR-4 materials.

As the most common type for rigid PCBs,FR-4 boards use a flame-retardant fiberglass layer for greater rigidity and flame resistance. These boards are lightweight and temperature- and moisture-resistant, making them an excellent choice for many applications.

When PCBs need to operate in high temperatures, high-Tg circuit boards have a glass transition temperature (Tg) over 150 degrees Celsius. If you’re working with high-power circuit density designs, heat that is generated may overwhelm a standard PCB’s heat management methods. High-Tg boards are the practical solution in these scenarios.

Finishes

Your rigid PCB will use a copper layer for an efficient electrical current flow and will need protection against corrosion and oxidation. Possible protective finishes include:

Electroless nickel immersion gold (ENIG).
Electroless nickel electroless palladium immersion gold (ENEPIG).
Immersion tin.
Hot air solder leveling (HASL).
Immersion silver.
Lead-free HASL.
Wire-bondable electrolytic gold.
Hard gold fingers.
