- Evolution of PCB Design: A Brief Overview
Let’s begin with how PCB design has evolved with time. The conventional designs of PCBs were not as diverse or flexible in terms of function and layout. They were primarily single-sided boards used for the most basic applications and were less complicated electronic settings. But with the boom of IoT devices, AI, machine learning, and automation, PCBs had to be made more advanced to handle more complex circuits and compact electronics.
Innovations in PCBs included multilayer boards, flexible PCBs, and HDI that made designs not only smaller but also more power-efficient and versatile. For further insight into the early development of PCB design evolution, click here.

A. Case Study 1: Tesla’s Autopilot PCB—Meeting High Power and Safety Demands
Tesla is one of the world’s pioneers in the field of automobiles, especially in electric and self-driving. The process of Autopilot does involve processing a huge amount of data online, so their PCB board is very complicated. Functioning under conditions such as high temperature and high-velocity data processing and an extreme degree of accuracy but with safety paramount.
Best Practices Highlighted:
- Thermal Management: Tesla’s PCB employs state-of-the-art thermal management techniques. High-power devices generally emit heat, and if not properly managed then it would have a detrimental effect on the performance and could even affect the lifespan of the device. So engineers at Tesla use copper planes and thermal via to dissipate heat.
- High-Speed Signal Processing: Autopilot is a real-time system, hence high-speed signal processing is employed in Tesla’s PCB. The design also has high-density interconnects and materials that minimize signal loss.
- Redundancy and Safety: In the automotive world, safety is of utmost importance. Tesla makes use of redundant paths and layers that will result in data and power continuity when part of the board fails.

B. Case Study 2: Apple Flexible PCBs in Wearables
Apple Watch has further extended the miniaturization of products into wearables. For Apple, the usage of flexible PCBs was made so that highly compact yet high-performing devices could be delivered. Flexibility with the least compromise in terms of durability and performance is more critical for the case of a daily-worn product.
Best Practices Highlighted:
- Flexible Materials: Apple’s FPCBs will be using polyimide substrates, which are quite heat-resistant and flexible would allow the circuit board to bend inside the device and hold up to daily wear.
- Optimization of Component Position: Apple uses advanced techniques while getting the optimization of component positions so that each part is located perfectly for efficiency, power management, and durability.
- Signal Integrity and EMI Control: Signal integrity and EMI control an important factors due to the small space and the proximity of the components. Apple has adopted a sophisticated shielding approach to overcome EMI challenges with its FPCB design.
