Hi everyone. Non-engineer here looking to validate an element of my
I am running a small research project which involves managing one PCB
designer. Our objective is to design a board capable of capturing low
amplitude biometric signals. We've been through many iterations of our
PCB but the signal is still very noisy compared to other devices used in
the same location on the body.
Our engineer says this is because hand-assembling PCBs inherently
results in a noisier board than machine assembly would (we've tried
machine assembly - still noisy). I wanted to validate whether or not we
should expect to see any difference in signal quality between hand
assembled boards and machine assembled boards?
