Half-pitch Board-to-Board Connectors XH3 Screw Mount Eliminated to Save Space. Adjustable Stacking Height of 12 to 20 mm. * The stacking height can be adjusted in 1-mm increments. * Mating length of 3.1 mm and a pitch of 1.27 mm for highdensity mounting in double-row arrangements. * All models incorporate fastening pins to secure the terminals, thus preventing floating or falling over during soldering. * Leaf contact construction enables smooth mating and resistance to bending. * The XH3 conforms to EN, IEC, UL (file no. E103202), and CSA (file no. LR62678).

Automated soldering Special Finish for Preventing Flux Rise Use tape to mask the Right-angle Terminal Connector prior to automated soldering. XH3 Connectors (i.e., Straight Terminals and standard size, 1-, and 2-mm increments) have a special finish that prevents flux rise. (The Connectors are designed for automated soldering. Brush coating flux from the back of the board applies too much flux and may nullify the special finish. Never use this method to apply flux.) Masking tape Automated Soldering Conditions (Jet Flow) 1. Soldering temperature: 2505C 2. Continuous soldering time: Within 5 s (Be sure to wash the board after continuous soldering is completed.)
