Minimum Spacing for SMD Components
Last updated on Jan 26, 2026
To improve assembly yield and process stability, JLCPCB specifies the following minimum spacing requirements for SMD components. These values are determined based on the following four key factors:
1. Component-to-component spacing between adjacent SMD parts.
2. Minimum spacing required for stencil apertures during solder paste printing.
3. Inspection and rework accessibility requirements, including AOI and manual rework.
4. Placement accuracy and tolerance of pick-and-place machines.
The table below lists the minimum recommended spacing for commonly used SMD packages.
