When designing data cabinets, home appliances, office equipment, cable junction boxes, or anything involving electronics, PCB hardware is integral. This guide will help you understand the different components that can enhance the performance of your printed circuit board design.
We strongly recommend trying the PCB hardware you need before buying — request samples to ensure they’re right for your application. You can also download free CADs to assist with your design.
A good starting point is to see what solutions are commonly used for certain applications.

Before choosing your hardware, you might find it helpful to read How to ensure a smooth PCB assembly. The information could help you decide which components you should use.
PCB supports, also known as PCB support pillars and support posts, do what the name says: they support the mounting of a PCB. They connect your PCB board to the required surface, providing insulation, protection from electrical transmission, and a more secure hold. Options include plastic and metal, with plastic making your PCB lighter.
PCB standoffs and spacers help maintain space and positioning of components. Spacers are unthreaded, while standoffs are threaded. They can be made from plastic, metal, or ceramic, each suited for different temperature and mechanical strength requirements.
Card guides are used to mount circuit boards in tight spaces like PCB racks, preventing bending and adding stability. They come in vertical or horizontal types with locking and adhesive back options for easy installation.
Card ejectors or pullers relieve stress on the PCB and its circuitry during removal from tight spaces. They provide a leverage mechanism to safely extract the card without damaging the circuitry.
Used for interconnecting solderless connectors to a PCB, mounting blocks provide electrical and mechanical connections between the chassis and the board.
Encasing electrical fuses, fuse covers provide insulation and protection from contamination and liquids.

LED components like LED spacers, mounts, and holders position and restrict LED movements, providing stability and height conformity. LED light pipes transmit light from the LED mounted on a PCB, offering excellent visual performance.
Used to secure panels, plastic screw grommets can securely fasten PCBs by expanding to lock heavy PCB components in place.
Materials play a critical role in PCB hardware performance. Options include:
