PCB panelization is the process of grouping multiple circuit boards into a single manufacturing panel. Proper panel design improves fabrication efficiency, simplifies automated assembly, and reduces production costs. This article explains PCB panelization guidelines including panel size selection, spacing between boards, breakaway methods such as V-cut and tab routing, and the use of tooling holes and fiducial marks. By following these Design for Manufacturing (DFM) rules, engineers can optimize production yield and ensure smooth PCB fabrication and assembly processes.

Solder mask is a protective layer applied to the surface of printed circuit boards to prevent solder bridges and protect copper traces. Proper solder mask design is essential for reliable PCB assembly and manufacturing yield. This article explains key solder mask design guidelines including mask clearance, mask expansion, pad openings, and common layout mistakes. By following practical Design for Manufacturing (DFM) rules, engineers can improve assembly reliability, reduce solder defects, and ensure compatibility with standard PCB fabrication processes.

PCB vias are critical structures that connect copper layers in multilayer printed circuit boards. Proper via design directly affects PCB manufacturability, electrical reliability, and production yield. This article explains the most important PCB via design rules, including via hole sizes, aspect ratio limits, annular ring requirements, and spacing guidelines. It also compares common via types such as through-hole vias, blind vias, buried vias, and microvias. By understanding these design parameters and aligning them with real PCB fabrication capabilities, engineers can...
