PCB Clearance and Tolerance Handbook

Sierra Circuits’ PCB Clearance and Tolerance Handbook provides practical guidance to turn your design requirements into a manufacturable board.

6 CHAPTERS

35 PAGES

30 MINUTE READ

The PCB Clearance and Tolerance Handbook helps you set adequate spacing between layout features/conductive elements and align your design with Sierra Circuits’ capabilities, so your board can be manufactured as intended.

Designing a reliable circuit board means choosing clearances that meet electrical and safety needs while staying within your fabricator’s capabilities. Proper spacing helps maintain signal integrity, reduce crosstalk, and prevent shorts.

This eBook offers practical guidance on trace spacing, copper clearances, ground planes, solder mask, drill-to-copper clearance, annular rings, and manufacturing tolerances. Use the PCB Clearance and Tolerance Handbook to translate your design requirements into specifications your fabricator can build to and to guide layout decisions throughout the design process.

What’s inside:

Recommended trace, copper, and ground plane clearances
Standards and electrical factors that influence spacing
Solder mask clearance and dam guidance
Drill-to-copper and annular ring requirements
Drilling, routing, and board tolerances
Capabilities for rigid, flex, HDI, RF, and high-speed boards
