What is Chamfer

A chamfer is a design feature used to eliminate sharp edges and create a smoother transition between surfaces on a printed circuit board. It involves making a small angled cut or bevel on the edge of the PCB, effectively removing the sharpness. Chamfers serve several purposes in PCB manufacturing.

Chamfer helps prevent damage to the board and other components during handling and assembly processes. By eliminating sharp edges, the risk of stress concentration, cracking, or chipping is significantly reduced. This is particularly important in applications where the PCB may be subjected to mechanical stress or vibration. They also improve overall durability and reliability. By removing sharp edges, the likelihood of stress-related failures is minimized. This is especially crucial in high-stress environments or applications where the PCB may experience frequent movement or impact.

Chamfers can be applied to various parts of a PCB, including the edges of the board itself, as well as cutouts, slots, or holes. The size and angle of the chamfer can vary depending on the specific design requirements and manufacturing capabilities.

Chamfers also have aesthetic advantages. They give the PCB a more polished and professional appearance, especially when visible through cutouts or openings in an enclosure.
