aluminum extrusion enclosures riveting processes for PCB Board

The riveting process is a method of connecting fasteners such as rivets or rivet nuts to workpieces by applying force.  During the riveting process, the applied force on the fastener creates a tight joint, securely fastening the workpieces together.

The advantages of the riveting process include:

1、 High-strength connection:  The riveting process provides reliable high-strength connections, allowing the workpieces to withstand greater forces and vibrations, thus increasing the stability and reliability of the connection.

2、Simplicity and speed:  Compared to other connection methods such as welding or bolted connections, the riveting process is simple to operate and efficient, enabling quick completion of the connection process.

3、No post-processing required:  Unlike welding, the riveting process does not require additional post-processing such as grinding or polishing, reducing process steps and time.

4、Disassembly capability:  Riveted connections can be relatively easily disassembled and re-fastened, making it suitable for situations that require maintenance and replacement.

5、Wide applicability:  The riveting process is applicable for connecting various materials, including metal-to-metal and metal-to-non-metal connections.

In summary, the riveting process offers advantages such as high strength, simplicity and speed, no post-processing requirement, and disassembly capability, making it a commonly used connection method in industrial production.

2、The common riveting processes for securing circuit boards to aluminum enclosures are as follows:

1、Blind riveting:  This is one of the most common riveting processes. It involves using rivets and rivet nuts to secure the circuit board to the aluminum enclosure. Firstly, holes are drilled into the aluminum enclosure, and then the rivets are inserted into the holes, expanding the tail of the rivets by applying force, and creating a tight joint.

2、Self-tapping thread riveting: This riveting process uses self-tapping thread rivets to secure the circuit board to the aluminum enclosure. Holes are drilled on the aluminum enclosure, and self-tapping thread rivets are used to create threads and fasten the circuit board. Self-tapping thread rivets provide a stronger fastening force and are easier to disassemble and re-fasten.

3、 Thread-forming riveting:  This riveting process uses thread-forming rivets to secure the circuit board to the aluminum enclosure. Thread-forming rivets are pressed into the aluminum enclosure, forming thread connections and fastening the circuit board. Thread-forming rivets provide reliable fastening force and can be disassembled and re-fastened when needed.

4、Hollow riveting:  This riveting process uses hollow rivets to secure the circuit board to the aluminum enclosure. Holes are drilled on the aluminum enclosure, and hollow rivets are used to expand the tail of the rivets by applying tension, creating a tight joint.

These are the common riveting processes, and the choice of a suitable riveting process depends on specific application requirements. Before riveting, ensure that the design and dimensions of the aluminum enclosure and circuit board are compatible, and perform necessary testing and verification to ensure reliable and stable fastening.
