Notes from the manufacturing floor.

Surface-mount technology suits small, dense and fine-pitch components, and it scales efficiently into production volumes.

Through-hole gives leaded parts a stronger mechanical bond, which matters for connectors, large capacitors, transformers and relays that see physical stress or heat.

Most real products use both. Mixed-technology assembly keeps the density of SMT and the strength of through-hole on one board, built by one team.

A ship date is only as good as the parts plan behind it. We review the BOM early and flag long-lead or hard-to-find parts before they hold up a build.

From there it comes down to a steady process on the floor and keeping customers informed, so there are no surprises on delivery day.

Prototypes are about proving the design. Production is about repeating it: stable footprints, locked-down part numbers and clear assembly notes.

Feedback from the first builds, such as DFM findings and part substitutions, should be folded into the documentation before volumes go up.
