The client’s surgical robot features a compact structure, where traditional connector solutions could not meet the required reliability. A rigid-flex PCB was implemented to achieve stable interconnection between two boards. We provided design guidance based on PCB manufacturing processes, strictly controlling distances: vias to rigid-flex junction ≥1mm, through-hole pins ≥1.5mm, flexible board vias ≥5mm; traces and pads to junction ≥0.5mm, via-to-via ≥0.5mm, via-to-trace ≥10mil. Through precise design and process optimization, the solution successfully met the high-reliability and bending requirements in limited space, with all technical specifications satisfying the client’s standards.
