Cable harnesses are crucial for connecting and powering components in electronic products, ensuring seamless functionality. However, designing these harnesses presents challenges that can delay development, increase costs, or compromise product quality.
This blog will explore the most common obstacles in cable harness design for electronic product development and demonstrate how Altium multi-board and harness tools provide practical solutions.
Modern electronic products frequently rely on multiple interconnected PCBs linked via cable harnesses and incorporating Commercial Off-The-Shelf (COTS) components. Ensuring accurate connections across these boards is critical to prevent costly errors.
Electronic product development often requires frequent design changes as prototypes evolve. Updating cable harness designs to match PCB layouts or component placement changes can be complex, time-consuming, and error-prone.
Cable harness design isn't just an electrical challenge. It must also work seamlessly within the product's physical constraints. Tight bends, sharp edges, and limited mounting options can lead to mechanical stress or cable wear over time. Properly securing cables and ensuring flexibility without sacrificing durability requires collaboration between mechanical and electrical teams, sometimes leading to design trade-offs.
Cable harness designs are becoming increasingly intricate, especially as electronic products become more compact and feature-rich. Without the right tools, design teams often face an increased risk of errors, inconsistencies, and inefficiencies—whether from overlooked electrical requirements, routing issues, or conflicting mechanical constraints. Also, managing an accurate and up-to-date Bill of Materials (BOM) for complex cable harnesses can be challenging, especially as designs evolve.
One of the biggest hidden challenges in cable harness design is ensuring seamless collaboration between OEMs and manufacturers. OEMs prioritize performance, integration, and compliance, while manufacturers focus on manufacturability, cost efficiency, and production scalability. Misalignment in design expectations, unclear documentation, and late-stage changes often lead to production delays, increased costs, and redesigns.
By leveraging Altium, OEMs and manufacturers can streamline communication, accelerate design validation, and reduce production risks, ultimately leading to a more efficient and cost-effective cable harness design process.
Cable harness design is critical, but it comes with hidden challenges – handling multi-board systems, adapting to rapid design iterations, integrating mechanical and electrical constraints, managing complexity and BOM accuracy, and ensuring seamless collaboration – all of which can significantly impact project timelines, costs, and overall product quality.
Altium solutions address these challenges head-on by providing powerful tools that help engineers streamline their design workflows, reduce errors, enhance manufacturability, and accelerate time to market.
