Standard plastic guides may soften or deform at high temperatures. Check the material's glass transition temperature (Tg) and consider metal guides for high-heat applications.
Card Guides Component Intelligence
Mechanical alignment and vibration management for PCB assemblies.
What are Card Guides components?
Card guides are essential mechanical hardware that ensure precise PCB alignment within subracks and enclosures. They prevent board flexing, facilitate smooth insertion, and provide critical vibration damping to protect sensitive interconnects and solder joints in high-density systems.
How to Choose Card Guides Components
Select card guides based on the mechanical environment and board physical constraints.
PCB Thickness
Ensure the guide slot width matches your PCB thickness plus tolerances to prevent binding or loose fit.
Material Selection
Use plastic for electrical isolation and cost; use metal or conductive plastic for grounding and heat dissipation.
Mounting Style
Choose between snap-in, rivet, or screw-mount styles based on your chassis material and assembly process.
Vibration Requirements
High-shock environments require locking or wedge-lock guides to prevent board dislodgement.
Length and Depth
Match the guide length to the PCB depth to ensure full-length support and prevent board bowing.
