Controlled Impedance PCB Layer Stackup

JLCPCB can produce High-precision multilayer board with capabilities listed in below table.

It is very convenient for customers to conduct an impedance matching design, according to JLCPCB鈥檚 laminated structure and related parameters. The PCB will be strictly produced in accordance with the following stackup.

Controlled Impedance PCB Parameters and Stackup

1.Prepreg dielectric constant:

2.Solder mask Parameters

3. Core dielectric constant

For your convenience, we have designed an Impedance Calculator to help you calculate the impedance and the trace width you require.
