PCB Spacers, Pillars & Supports

PCB spacers, pillars, and supports are essential for electronics and printed circuit board (PCB) assembly. These components provide mechanical support, alignment, and spacing for various electronic elements on a PCB. Designers and engineers must select the appropriate type and material of these components based on the specific requirements of their applications to achieve optimal performance and durability.

Key Functions of PCB Spacers, Pillars & Supports

• Mechanical Support: PCB spacers, pillars, and supports offer physical support to electronic components, preventing damage caused by vibration, shock, or mechanical stress.
• Alignment: They ensure precise alignment of components, connectors, and PCBs during assembly, improving the overall reliability of the circuit.
• Spacing: These components maintain specific distances between PCB layers or components to prevent short circuits, enhance airflow, and aid heat dissipation.

Different Types of PCB Spacers, Pillars & Supports

• Round Spacers: Round spacers are cylindrical and are often used to separate PCB layers, secure screws, or provide clearance between components. They come in various materials, such as plastic, metal, or nylon.
• Hex Spacers: Hexagonal spacers have a hexagonal cross-section, offering better grip and preventing rotation during assembly. They are commonly used in applications requiring stability and strength.
• Threaded Pillars: Threaded pillars have threaded ends, allowing for easy attachment of screws, bolts, or standoffs. They are ideal for securing PCBs inside enclosures.
• Self-Adhesive Supports: Self-adhesive supports have an adhesive backing that simplifies installation, eliminating the need for additional fasteners. They are often used in applications where ease of assembly is essential.
