What is a Double Sided PCB?

A double-sided printed circuit board has conductive copper tracks etched on both the top and bottom surfaces. Components are mounted and soldered onto the tracks on both sides. The two sides are connected by plated through holes called vias. This allows greater component density and more complex circuit designs.

Double-sided PCBs are commonly used in products like electronics, telecommunications devices, industrial control units, medical equipment, aerospace avionics, and more. The key advantages are reduced size and increased functionality.

JHYPCB's Double Sided PCB Fabrication Process

At JHYPCB, we use advanced manufacturing technologies and techniques to fabricate high-quality double-sided PCBs:

We start with a dielectric substrate material like FR-4 and use precision lithography to transfer the circuit pattern onto both sides.
Next, chemical etching removes unwanted copper to leave behind the desired tracks.
Drilling forms the holes and vias, which are then plated with copper to form connections between layers.
A solder mask is applied to protect the copper traces, while exposing pads.
Silkscreen printing labels components placements and identifications.
Finally, a protective finish like ENIG, HASL/Lead-free HASL, Immersion Tin, or OSP is added.

We perform extensive testing and inspection after each process stage to ensure perfect layer-to-layer registration and reliable plated through-hole connections on the finished boards.

Double Sided PCB FAQs

What types of materials are used to make double-sided PCBs?

The most commonly used materials for double-sided PCBs are FR-4 (a type of fiberglass epoxy) and polyimide (a high-temperature plastic).

What is the difference between a double-sided PCB and a multi-layer PCB?

A double-sided PCB has circuits and components on both sides of the board, while a multi-layer PCB has multiple layers of circuitry separated by insulating material.

What is the typical copper thickness used for double-sided PCBs?

The copper thickness used for double-sided PCBs can vary depending on the application, but the most common thicknesses are 1 oz, 2 oz, and 3 oz.

What is the difference between through-hole and surface mount components in a double-sided PCB?

Through-hole components have leads that go through holes in the PCB and are soldered on the other side, while surface mount components are mounted directly onto the surface of the PCB.

Can double-sided PCBs be used for high-frequency applications?

Yes, double-sided PCBs can be designed for high-frequency applications, but special attention needs to be paid to the placement of components and routing of traces to minimize interference.

What is the maximum size of a double-sided PCB?

The maximum size of a double-sided PCB is limited by the manufacturing process and the size of the materials used. Generally, double-sided PCBs can be made up to several feet in size, but larger sizes may require a different manufacturing process.

Can double-sided PCBs be made for prototyping and low-volume production?

Yes, double-sided PCBs can be made for prototyping and low-volume production. Many PCB manufacturers offer prototyping and small-batch services for double-sided PCBs.

How are vias used in double-sided PCBs?

Vias are used to connect circuits on both sides of the PCB. They are drilled through the board and lined with conductive material, allowing current to flow between the layers.

What is the difference between blind vias and through vias?

Blind vias connect one or more inner layers of the PCB to one or both outer layers, while through vias connect all layers of the PCB.

How are solder mask and silkscreen used in double-sided PCBs?

Solder mask is a protective layer applied to the surface of the PCB to prevent solder from flowing where it's not supposed to. Silkscreen is a layer of ink applied to the surface of the PCB to identify components and provide additional information.

What types of surface finish are used in double-sided PCBs?

The most common types of surface finish used in double-sided PCBs are electroless nickel immersion gold (ENIG), immersion silver, HASL Lead Free, and organic solderability preservative (OSP).

What is the typical lead time for a double-sided PCB order?

The lead time for a double-sided PCB order can vary depending on the manufacturer and the complexity of the design, but typical lead times range from several days to several weeks.

What is the cost of a double-sided PCB?

The cost of a double-sided PCB depends on the size, complexity, and quantity of the order, as well as the type of materials and manufacturing processes used. Generally, double-sided PCBs are more expensive than single-sided PCBs but less expensive than multi-layer PCBs.

How do I choose the right PCB manufacturer for my double-sided PCB?

When choosing a PCB manufacturer for your double-sided PCB, consider factors such as experience, certifications, capabilities, lead times, and customer service. It's also important to ask for references and samples of previous work.

Can double-sided PCBs be repaired?

Double-sided PCBs can be repaired, but the process can be more challenging than repairing a single-sided PCB. Repairing a double-sided PCB may require removing components, drilling new holes, and re-routing traces, among other tasks. It's often more cost-effective to replace a damaged double-sided PCB rather than attempting to repair it.
