Successful electronics blog start with professional PCB design that balances electrical performance, manufacturability, and cost. While many advertise "PCB design services," few deliver comprehensive expertise: high-speed PCB design for multi-gigabit interfaces, RF PCB design for wireless systems, HDI PCB design for miniaturization, impedance-controlled PCB design for signal integrity, or automotive PCB design meeting IATF standards.

Design failures manifest in manufacturing. High-speed PCB layout without proper termination causes signal integrity issues. RF circuit board design with poor ground planning degrades wireless performance. Power PCB design lacking thermal analysis leads to component failures. Flexible PCB design ignoring bend radius results in copper cracking. Medical device PCB design missing safety isolation creates regulatory failures.

Pricing depends on complexity, layer count, component density, and special requirements. Prototype builds often include design services.

Q3: What's the difference between high-speed PCB design and standard layout? High-speed design requires controlled impedance (±10%), differential pair routing, length matching (<5mil intra-pair), termination strategies, and SI simulation.
