Multilayer high precision PCB's with impedance control

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

Min. Trace width/Spacing Min. Via Min. BGA
3.5mil 0.2mm 0.25mm

It is very convenient for customers to conduct an impedance matching design, according to JLCPCB’s 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:

Prepreg type Dielectric constant
7628 4.4
3313 4.1
1080 3.91
2116 4.16

2.Solder mask Parameters

Coating Above Substrate C1 Coating Above Trace C2 Coating Between Traces C3 Coating Dielectric CEr
1.2mil 0.6mil 1.2mil 3.8

3. Core dielectric constant

Core dielectric constant
4.6

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