Pcb Assembly
An updated overview of PCB assembly options for small manufacturers - from hand-soldered through-hole boards and pick-to-light stations to modern SMT pick-and-place lines and selective soldering.
Lead Free Solder
Lead-free solder (commonly SAC305) became standard after RoHS. It requires higher temperatures, different fluxes and equipment adjustments, and produces less shiny joints and reduced through-hole top-fill - but reliable assemblies are achievable with proper process control.
