Hirose has introduced the FH53 range of flat printed circuit (FPC) connectors for small portable electronic devices that require high-speed transmission. The connectors offer excellent impedance characteristics and deliver high-density transmission required to support Embedded DisplayPort ver1.3 and MIPI D-PHY ver1.1 standards.
The dimensions are compact with a short mounted depth of 3,2 mm, a height of only 0,65 mm and a fine pitch of 0,2 mm to minimise the required mounting area, saving valuable board space. The connectors are available with 19 or 31 contacts (others available on request) and are rated to 0,2 A and 30 V a.c./d.c.
Two multi-functional metal fittings are incorporated into the connector housing to support correct tabbed FPC insertion/withdrawal and to hold the FPC in place temporarily before the locking operation. A firm and tactile click confirms correct locking of the FPC has been achieved. When locked, the metal fittings close to hold the FPC tabs firmly in place to ensure high retention of the FPC.
The contact design features a sharp protrusion in the bottom section that presses up into the FPC stiffener to increase the retention force to 9,9 N in the horizontal direction. In addition, each contact and metal fitting supports the actuator axle during rotation to hold the actuator securely in place.
Solder wicking from the surface-mount termination area to the contact points is prevented by a nickel barrier. Clearances are provided at the sides of the contacts/metal fittings and the housing to prevent flux penetration.
