The 4-wall shrouding also protects the pins from bent-contact damage during blind mating. ## Termination Options: Press-Fit and Solder Listed with both press-fit and solder termination, this header supports two assembly methods. Press-fit eliminates the solder wave for high-reliability backplane builds where rework is difficult; the through-hole solder tail gives a conventional joint for standard wave-solder lines. The square pin shape provides consistent contact geometry for both processes. ## Tin Plating for Cost-Effective Signal Duty The brass contact material provides adequate spring properties for the insertion force range of a single-row header.","metaTitle":"Molex 0532581229 Header 12 Pos 3.5mm Pitch Locking Ramp","metaDescription":"Molex 53258 series header, 12 positions, 3.50 mm pitch, shrouded 4-wall, locking ramp, tin-plated contacts, UL94 V-0, active production.
