Why is there no right angle on PCB?

Time:2019-05-16 17:31:03 Click:

I guess, you wanna try to express why there is no right angle trace on PCB. Well, it’s just because that the corner(not right angle) trace can be as capacitive load like a transmission line, which is pretty helpful to retard rise time;


Furthermore, if we use right angle trace on PCB whose discontinuous impedance will definitely cause reflection of signal as well as EMI will be generatedon the tip of right angle trace.


PS: With the right angle trace on PCB, the signal frequency processed by PCB engineers will continue to increase; As long as it’s over 10G Hz in RF design, which is extremely possible to be a serious problem in terms of solving high speed.
