Construction

Faces of a CubeSat and some uses

Left/right sides – often totally covered in solar cells

Front – access port for RBF, PC link, antenna, etc.

Rear – Often with sensor, antenna, etc.+ solar cells

Top/bottom – antennas, sensors, etc. Usually the fewest solar cells here

Shock / G-loads

Not a major issue, in that CubeSats don’t seem to have much trouble surviving shake table tests and launch. Some delicate components may pose issues (e.g. solar cells). Delfi-C3

Fasteners should be staked or potted. Conformal coatings on PCBs are probably a good idea, but not required.

Tin Whiskers

More and more components are RoHS/Pb-free. Aerospace technically exempt in most markets. Limited lifespan mitigates this problem somewhat.
