Not sure if this has been posted before but thought was interesting.
The thickness of the copper trace must allow for this. They will know the amount of trace failures by the QC rejection rate and warranty claims.I am surprised they let the PCBs flex so much during assembly. That's just asking for hairline-broken traces.
I was thinking maybe they are trying to induce early failure to weed out the weak boards. The amp will vibrate a lot as well, better find the problem in the factory instead of field.The thickness of the copper trace must allow for this. They will know the amount of trace failures by the QC rejection rate and warranty claims.
I was also surprised by that amount of flex, but it must be common throughout at least some parts of the electronics industry.
Living in Scarborough during late high school, litterally 2 401 exists away from the factory, we used to head out there in the dead of a weekend night to dumpster dive. They'd throw out all sorts of perfectly good things; speakers for example. Now they have security that prevents that.Pickering you say? I live there and didn't even know about this!
Very interesting! Thx for sharing.
