38 I-CONNECT007 MAGAZINE I AUGUST 2026 The reason is that electronic systems have become too complex for any single discipline to optimize independently. Modern designs are a combination of high-speed digital interfaces, RF functionality, advanced packaging, power delivery challenges, thermal constraints, HDI structures, and global supply chains, all of which can change throughout the product lifecycle. For example, I've seen that a decision made by one engineering group rarely remains isolated. A component choice might influence placement, via technology, routing, thermal performance, manufac- turing complexity, and long-term availability. In other situations, a stackup decision could affect SI, power integrity, cost, and fabrication yield. A mechanical change can create electrical consequences that were never considered during the original architec- ture. The PCB has become the physical point where these competing requirements meet. In the past, product development often followed a sequential path where each discipline contributed its expertise, but often only after the previous disci- pline had completed its work. But what I've found is that the earlier the conversations happen, the fewer problems have to be fixed later. My most successful projects weren't because a final design review discovered every possible issue before manufacturing. They succeeded because the right conversations happened earlier in the process. Manufacturing engineers influ- enced fabrication decisions before the routing was complete. Mechanical engineers would collaborate during placement, rather than after the board was constrained. SI analysts shaped routing strategies before critical nets became too difficult to modify. Procurement teams identified component risks while alternatives were still available. The difference was that every stakeholder became part of the design process rather than a reviewer of completed work. This is where the concept of an engineering ecosystem becomes so important. Everyone Contributes in a Healthy Ecosystem No single organism operates independently, and the stability of the system depends on the relation- ships between all participants. Engineering organi- zations function in the same way. • Program managers establish business objectives, schedule, and priorities • System architects define the technical vision • Electrical engineers establish functionality • Mechanical engineers define physical realities • Manufacturing engineers ensure producibility • Quality teams establish reliability expectations • Procurement teams manage supply chain considerations " Design for assembly, design for test, design for reliability, design for cost, and design for supply chain are not separate activities competing for attention. They are interconnected perspectives that contribute to the overall health of the engineering ecosystem."
