I also have a chair that is high enough so I can alternate sitting and standing. Even if you end up sitting most of the time as I do these days, it is still well worth it.

A modern PCB serves not just as a means to interconnect components, but also as a mechanical structure, heat conductor, noise shield, and even as a circuit element, and must go through a complex automated manufacturing process to boot.

Perhaps it is best to start with (more…)
