Selecting the Right PCB Cable Assembly Components
The PCB cable assembly is crucial to the overall performance of an electrical appliance. However, to ensure optimal performance from the PCB wire harness, the methods concerning arrangement and cabling type must be clearly defined. The choice of PCB cable assembly components will dictate the effectiveness of the assembly during its application.
The Circuits
Every cable necessitates a network of conductors or wires to ensure superior performance. The conductors serve as the fundamental pathways for electrical flow, thereby exerting a substantial influence on the performance of the PCB wire harness. A complete circuit necessitates the presence of a conductive material, strands, and plates.
Copper is often the preferred conductive material due to its affordability and compatibility with various coatings. It offers superior current termination and corrosion resistance, making it the ideal choice in most cases.
Given its susceptibility to corrosion, copper must be coated with other materials to mitigate this issue and enhance its durability. Depending on the specific needs of the PCB cable assembly, you can choose between multiple or single strands, which contribute to the flexibility of the final product.
The PCB Cable Assembly Insulation
Once the appropriate conductor has been selected, the next step involves determining the method of insulation for the conductor. Here, two primary materials can be utilized for superior insulation: thermoplastic and thermoset materials. The choice between these materials largely depends on the type of conductors used during the production of the PCB wiring harness.
For better insulation selection, also keep in mind the following aspects:
Voltage level
- Moisture and chemical exposure
- External environment nature
- The operating temperatures
- The right insulation protects the PCB cable assembly underlying layer from the above conditions.
The Right Shielding
Since the PCB will be exposed to various electromagnetic environments, it is essential to select a material capable of safeguarding the assembly's conductors. This helps prevent any potential dips in performance during application.
The outer Jacket or Sheath
The jacket serves to protect the internal components of the PCB cable. Consequently, it must possess qualities such as toughness, chemical resistance, and fire resistance, among others. Depending on the specific application, it is also advisable to choose a jacket that has some degree of electrical conductivity. Options for such sheathing include PVC, Elastomer, or fluorocarbon.
The Connectors
Connectors play a crucial role in any PCB cable assembly system. They determine the overall compatibility of the system and influence its performance based on the signal and speed in use.
Welded connectors are often the preferred choice due to their high-speed capabilities. However, crimp connectors can also be effective in certain applications.
