This paper investigates a meticulous approach to validate Printed Circuit Board (PCB) designs specifically tailored for Anti-lock Braking System (ABS) products within the automotive sector. The primary focus is on the application of Design for Manufacturability (DFM) and Design for Assembly (DFA) principles to optimize the reliability, manufacturability, and efficiency of ABS PCBs. The paper presents detailed analyses, case studies, and practical insights into integrating DFM and DFA in ABS PCB design and validation processes.
