impedance-controlled-pcb. from 4 layer to 50 layer boards. we produce the boards with 50 OHM, 90 OHM, 100 OHM. the tolerance is +/-10%.
If you do not know how to design the Impedance controlled. I mean the PCB Stackup info. do not worry. please tell me. our engineer will help you to make a PCB Stackup info. and We’ll figure out the impedance for you.
And for our new customer. we will produce some free PCB samples to you. to check the PCB quality at first. than. you will like the PCB quality.
