Components are through-hole mounted on one side and surface mounted on the other.
The individual is inquiring about the potential drawbacks of having through-hole connectors on one side of the board and everything else, such as surface-mounted components, on the other. They are questioning whether this assembly makes selective or wave soldering more challenging and considering consolidating all components on the same side if feasible.

Pads with silkscreen printing
The individual is puzzled by the discovery of solder-masked and silkscreened pins on a TQFP package, and is seeking explanations for the purpose behind this rather than leaving the pins unsoldered. They also question the decision to silkscreen the pads instead of using solder mask. They speculate potential reasons for these design choices and seek insights from the community.
Isolating primary power traces on the reverse side of the PCB
The speaker is building a low-power internal PSU for their audio-effect-rack and wants to prevent contact between the PCB’s mains power traces and the case. They are considering options, such as painting the backside or using a plastic sheet.
