Why Use Our Calculator Instead?
Via Current Analysis
JLCPCB's calculator doesn't include via current capacity calculations. Our tool helps you design proper thermal via arrays and determine PTH current limits for power delivery.
Differential Pairs
Calculate differential impedance for USB, HDMI, and high-speed signals. Essential for modern PCB designs that JLCPCB's basic tool doesn't support.
No Login Required
Start calculating immediately without creating an account or logging in. JLCPCB requires authentication for their tools—we believe calculations should be instantly accessible.
About JLCPCB
JLCPCB (Shenzhen JLC Electronics Co., Ltd.) is one of the largest PCB manufacturers in China, known for extremely low prices and fast turnaround times. They offer a basic trace width and impedance calculator as part of their service.
While JLCPCB is excellent for manufacturing, their calculator tools are limited in scope. TraceWidthCalculator.com provides more comprehensive analysis without requiring you to create an account or be locked into any manufacturer.
Use our calculator for design planning, then order your boards from JLCPCB, PCBWay, or any manufacturer that meets your requirements.

Frequently Asked Questions
Are the calculations the same as JLCPCB?
Yes. Both calculators use IPC-2221 standards for trace width calculations. Results should be identical for the same input parameters.
Should I still use JLCPCB for manufacturing?
Absolutely! JLCPCB is great for PCB manufacturing. Use our calculator for design, then order boards from any manufacturer you prefer.
Why doesn't JLCPCB have via current calculations?
JLCPCB focuses on manufacturing services, so their calculator covers basic needs. Our tool is dedicated to comprehensive PCB design calculations.
Is this affiliated with JLCPCB?
No. TraceWidthCalculator is an independent, free tool. JLCPCB is a trademark of Shenzhen JLC Electronics Co., Ltd.
