Control impedance PCB
Many customers asked us what information we need for impedence
control PCB.Here,there are two types for PCB manufacturer,a is
single impedance, just one trace , two holes. and b is differential
impedance,it always go with 1 pair (two trace with same width and
space). For single impedance,you just tell us the trace width one
which layer and what value you require .For differential
impedance,trace width/space,layers and value. Our experience
engineers will calculate following your instruction with Polar
software.We may change trace width/space or stackup ,but please do
not worry, if any changes,we will send you to approve before
proceeding. Generally,the tolerance is 10%,and more accurate is 8%
.All impedance boards ,we will test here and report.
Here is an example of what information we need to do impedance
control.
TYPE | VALUE | Layer | width/space |
---|---|---|---|
Single | 50 ohm +/-10% | L1,L6 | 0.15mm |
Single | 50 ohm +/-10% | L2,L3,L4,L5 | 0.13mm |
Differential | 90 ohm +/-10% | L1,L6 | 0.13/0.13mm |
Differential | 100 ohm +/-10% | L1,l6 | 0.13mm/0.2mm |
