PCB Layout: Small Mistakes Can Lead to Heavy Losses

2026-03-25

In the meticulous field of circuit design, even the tiniest error can have incalculable consequences. Engineers must conduct a thorough and careful review of every step after completing the design. Last week, a colleague finished his board design and sent it for prototyping. During wave soldering, a 4‑pin header could not be inserted. The SMT assembly factory reported that the SOIC‑8 power IC on the backside was overlapping with the header, making insertion impossible.

After the entire PCB design is completed, the circuit board needs to be mounted with components on the SMT assembly line. Each SMT manufacturing factory specifies the appropriate board size according to the processing requirements of the assembly line. If the board size is too small or too large, the fixture for fixing the board on the assembly line cannot hold it.

PCB Design Optimization Guide: How to Maximize EMC Performance

2026-03-23

In PCB EMC design, layer setup comes first. The total layer count consists of power layers, ground layers, and signal layers. Besides component selection and circuit design, sound PCB layout is critical for product EMC performance. The core of PCB EMC design is to minimize return current loops and guide return paths along intended routes. Proper layer design is the foundation for optimal EMC.
