About this Calculator:
The PCB Solder Mask Expansion Calculator helps determine the appropriate solder mask opening size based on pad dimensions and mask parameters. This ensures proper solder mask application and reliable solder joints.
IPC Guidelines:
- Minimum expansion: 0.05mm per side
- Typical expansion: 0.05-0.1mm per side
- Maximum expansion: Based on pad spacing
When designing multilayer PCBs, proper stackup design is crucial for signal integrity and EMI control. This PCB Stackup Designer Calculator helps engineers optimize layer configurations and material selection for multilayer PCB designs. For comprehensive PCB design, you'll also need tools like the PCB Trace Resistance Calculator to minimize power loss, and the PCB Via Size and Current Capacity Calculator to ensure proper current handling. High-speed designs require the PCB Impedance Calculator for maintaining signal integrity, while the PCB Heat Dissipation & Thermal Resistance Calculator helps optimize thermal management. Don't forget to check parasitic effects with the PCB Capacitance Calculator and PCB Inductance Calculator. These free tools work together to help you create reliable, high-performance PCB designs.
