Our newest column shares tips and tricks and lessons learned over 30 years in PCB design.

With today's complex printed circuit board (PCB) designs challenging us at almost every stage of the design process, along with shortened project schedules and shrinking budgets, achieving success is no easy feat. Smaller component packages, faster signal edge rates or rise times, and increased design for manufacturing (DfM) challenges all make it difficult to achieve success and get product to market on time and under budget. The foundation for achieving success is understanding PCB design (the full design process) and mastering the power of today's EDA tools.

Even so, design teams can lose valuable time on unproductive tasks. Designers need a collaborative approach to electronic systems design that keeps them connected through all engineering disciplines and gives them best-in-class solutions to handle complexity across the entire PCB design process.

Greg Papandrew Understand the landed cost before turning procurement over to EMS.

A good EMS partner brings real value. It manages assembly labor, SMT placement, inspection, test, rework, box build, documentation, scheduling and production discipline. That is what it is paid to do. EMS companies exist because OEMs need manufacturing execution without necessarily running a factory. In the standard EMS model, the EMS may also handle procurement, supply chain coordination and material sourcing on behalf of the OEM. That is normal. It is also convenient.

Greg Papandrew Hidden subcontracting in offshore PCB sourcing can expose OEMs and EMS providers to latent quality risks.

You’ve done your homework. You evaluated a new PCB supplier in China, negotiated a great piece price and placed your order. Weeks later, the boards arrive at your dock. They pass incoming inspection, hit the assembly line and everything seems fine.

Greg Papandrew The current US board market is spookier than it seems.

The email confirmation hits your inbox: Order Received. Status: In Process.

For a procurement manager or lead engineer, that notification usually triggers a dopamine hit. It’s the sound of progress. You’ve successfully navigated the internal approvals, you’ve selected a domestic vendor to avoid the headache of customs and the sting of new tariffs, and you’ve kept your supply chain close to home. You have done everything right.
