_ Board to Board Connectors ~AMP 1.25mm F-P Board-to-Board Connectors Features Economical board-to-board interconnection connector of ultra-lightweight and ultra-thin construction. WSingle-row and dual-row versions available, enabl- ing either parallel or right-angle interconnec- tion of boards by way of receptacle header mating with post header BBLoose-piece and reel- mounted products for auto- matic board packaging. Accepts 0.6-to 0.8mm- thick glass-epoxy boards. Two mounting styles solder dip-mounting and SMT (surface-mounting type); contacts are on a 1.25mm pitch for ultra- high-density packaging. MiDesigned for the highest ~ reliability and economy of board Interconnection. Today, the electronics industry is faced with an ever-growing demand for not only miniaturization of component parts for equip- ment, but also improved productivity through auto- matic packaging and the resultant reduction of equipment cost in order to keep pace with the fast- progressing market trends towards lighter, thinner, shorter and smaller products as seen in various portable equipment such as the camera-incorporated VTR. AMP 1.25mm F-P Con- nectors have been developed 3s an ultra-high-density board-to-board interconnec- tion connector that can meet all of these industry requirements and has the best adaptability to packaging The connector is offered in two versions, single-row and dual-row connectors. Both are available in two configurations. One ts a DtP-type which is mounted into the board holes by soldering and the other is a SMT-type(surface-mounting type) which can effectively utilize both front and back sides of the board to package more electronic components in the form of chips and increase the board's versatility The connector consists of a receptacle header and a post header. The receptacle header comes tn two styles, horizontal mounting and vertical mounting. The horizontal-mounting receptacle header mates with a post header (vertical mounting) and interconnects boards at a right angle, while the vertical-mounting receptacle header intercon- nects boards in parallel. For the SMT type connec- tors, receptacle headers are tape-mounted and wound on a reel to be compatible with automatic tape- "packaging machines used for other chip components. The post header is of a vertical-mounting type and available as both loose-pieces and PVC- encased parts. There is also on interme- diary post header version which accepts a variety of receptacles at both ends. 67 Performance Data Rated voltage: 50V AC/DC Rated current: O0.5A Low-level resistance: 1Om2 , max.
