about board spacers and standoffs component class recommendation.
Board spacers and standoffs are essential components in electronic assemblies. They are used to create a gap between the printed circuit board (PCB) and the chassis or enclosure. This gap is necessary to prevent the PCB from shorting against the metal surface of the enclosure. Board spacers and standoffs also provide mechanical support to the PCB, preventing it from bending or flexing under stress.
There are many different types of board spacers and standoffs available, each with its own unique features and benefits. In this article, we will discuss the various types of board spacers and standoffs and provide a component class recommendation for each type.
1. Round Spacers
Round spacers are the most common type of board spacer. They are cylindrical in shape and come in a variety of lengths and diameters. Round spacers are typically made from nylon or brass and are available in both male and female configurations.
Component Class Recommendation: Nylon round spacers are recommended for most applications. They are lightweight, non-conductive, and have good mechanical strength. Brass round spacers are recommended for applications where higher strength is required.
2. Hex Standoffs
Hex standoffs are similar to round spacers, but they have a hexagonal shape. This shape makes them easier to grip and tighten with a wrench or pliers. Hex standoffs are available in both male and female configurations and come in a variety of lengths and diameters.
Component Class Recommendation: Brass hex standoffs are recommended for most applications. They are strong, durable, and have good electrical conductivity. Nylon hex standoffs are recommended for applications where non-conductivity is required.
3. Threaded Standoffs
Threaded standoffs are similar to hex standoffs, but they have threads on both ends. This allows them to be screwed into both the PCB and the chassis or enclosure. Threaded standoffs are available in both male and female configurations and come in a variety of lengths and diameters.
Component Class Recommendation: Brass threaded standoffs are recommended for most applications. They are strong, durable, and have good electrical conductivity. Nylon threaded standoffs are recommended for applications where non-conductivity is required.
4. Swage Standoffs
Swage standoffs are similar to threaded standoffs, but they do not have threads. Instead, they have a smooth shank that is swaged or pressed into the PCB. Swage standoffs are available in both male and female configurations and come in a variety of lengths and diameters.
Component Class Recommendation: Brass swage standoffs are recommended for most applications. They are strong, durable, and have good electrical conductivity. Nylon swage standoffs are recommended for applications where non-conductivity is required.
5. Snap-In Standoffs
Snap-in standoffs are designed to snap into a hole in the PCB. They are available in both male and female configurations and come in a variety of lengths and diameters.
Component Class Recommendation: Nylon snap-in standoffs are recommended for most applications. They are lightweight, non-conductive, and easy to install. Brass snap-in standoffs are recommended for applications where higher strength is required.
6. Adhesive Standoffs
Adhesive standoffs are designed to be glued onto the PCB. They are available in both male and female configurations and come in a variety of lengths and diameters.
Component Class Recommendation: Nylon adhesive standoffs are recommended for most applications. They are lightweight, non-conductive, and easy to install. Brass adhesive standoffs are recommended for applications where higher strength is required.
Conclusion
In conclusion, board spacers and standoffs are essential components in electronic assemblies. They provide mechanical support to the PCB and prevent it from shorting against the metal surface of the enclosure. There are many different types of board spacers and standoffs available, each with its own unique features and benefits. The component class recommendation for each type depends on the specific application requirements. By selecting the right board spacers and standoffs, you can ensure the reliability and longevity of your electronic assemblies.
