What this 12-position 2 mm header does in the assembly
The 1-440054-2: This is a single-row, 12-position header from TE's High Performance Interconnect (HPI) series, designed to connect a board to a cable or wire assembly.
Termination options: press-fit or solder
The termination is listed as both press-fit and solder. Press-fit allows a solderless backplane assembly where the compliant pin cold-welds into the plated through-hole — eliminates reflow defects and simplifies rework. Solder gives a standard through-hole connection for conventional wave or hand-solder processes.
