About PCB Annular Ring Width Calculator:
The PCB Annular Ring Calculator helps determine the appropriate annular ring width for vias and plated through-holes. A proper annular ring is crucial for reliable connections and manufacturability.
IPC Guidelines:
- Minimum annular ring: 0.05mm (2 mil)
- Recommended minimum: 0.125mm (5 mil)
- Typical range: 0.125-0.25mm (5-10 mil)
When designing PCBs, proper annular ring width is crucial for reliable through-hole connections. This PCB Annular Ring Width Calculator helps engineers optimize pad and hole dimensions. 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 and PCB Differential Pair Impedance Calculator for maintaining signal integrity. For manufacturing reliability, use the PCB Solder Mask Expansion Calculator to determine proper mask openings, 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.
