Use nylon when you need electrical isolation between the PCB and the chassis or to reduce overall assembly weight. Metal is preferred for grounding the PCB to the chassis or for high-vibration environments.
Board Supports & PCB Standoffs Component Intelligence
Mechanical stability and isolation for PCB assemblies
What are Board Supports & PCB Standoffs components?
Board supports provide the necessary mechanical clearance and structural integrity for PCBs within an enclosure. Selection depends on mounting method (snap-in, adhesive, or screw), material (nylon for isolation, metal for grounding), and vibration requirements.
How to Choose Board Supports & PCB Standoffs Components
Selecting the right support requires balancing mechanical load, assembly speed, and electrical requirements.
Mounting Method
Choose snap-in for rapid assembly, screw-mount for high-vibration, or adhesive for chassis without mounting holes.
Material Selection
Use Nylon 6/6 for electrical isolation and weight reduction; use brass or steel for grounding paths and high-stress applications.
Standoff Height
Ensure the height provides sufficient clearance for bottom-side components and airflow requirements.
Hole Diameter
Match the support's locking head diameter to the PCB mounting hole tolerance to prevent movement or board cracking.
Environmental Rating
Consider UL94 V-0 flammability ratings for high-temperature or enclosed power electronics.
