Characteristics of Double-Sided PCBs

Double-sided PCBs have special features for advanced uses:

• Two copper layers: Both sides hold circuits, increasing design space.

• Through-hole method: Holes link parts on the top and bottom.

• Better connections: Tracks and holes join parts for detailed designs.

• Material effects: Things like air bubbles and copper texture affect performance.

Advantages of Double-Sided PCBs

Double-sided PCBs have many helpful benefits:

• More complex circuits: They allow for detailed and advanced designs.

• Smaller size: Using both sides saves space in devices.

• Affordable option: They balance cost and functionality well.

• Improved performance: They handle heat better and connect parts efficiently.

Applications of Double-Sided PCBs

Double-sided PCBs are used in many fields:

• Electronics: Phones use them for compact and smart designs.

• HVAC systems: They help heating and cooling machines work well.

• Power supplies: UPS systems use them for better performance.

• Aerospace: Autopilot systems use them to manage heat in GPUs.

Double-sided PCBs are affordable, flexible, and efficient, making them ideal for today’s electronics.

Multilayer PCBs: Advanced Solutions by LT CIRCUIT

What Are Multilayer PCBs?

A multilayer PCB has three or more conductive layers. These layers are stacked with insulating materials in between. This design allows for small and complex circuits. Unlike single-sided or double-sided boards, multilayer PCBs work better for advanced electronics.

At LT CIRCUIT, these boards are made carefully for modern needs. They handle tough circuits while staying reliable and efficient. Whether you need 4 layers or 40 layers, LT CIRCUIT offers options to fit your requirements.

Characteristics of Multilayer PCBs

Multilayer PCBs have unique traits that make them special:
