History FFC/FPC
1970's, Flat Flexible Cables (FFC) were adopted standard interface jumper between printed circuit boards. While these cables provided design engineers significant packaging flexibility, termination technology limited only methods: Direct Solder: permanent connection cost applications. Crimped Contacts: separable connection high plugability. Seeing need cost effective termination solution, Elco developed first card edge style connector 1986 which would mate directly FFC. This Insertion Force (LIF) type connector provided simple reliable mating unmating cable printed circuit board. Elco's 8370 Series quickly became industry standard cost effective terminations. 1987, Elco introduced first Zero Insertion Force (ZIF) connector, Series 6200, which provided increased mating unmating (durability) cycles. Since that time, Elco continued lead industry with state-of-the-art products. Today offer over different product series flex circuits ranging between 1.25mm 0.50mm pitch.
FFC/FPC COMPOSITION
Flat Flexible Cable (FFC) made thin rectangular copper conductors laminated between layers polyester insulation. These copper conductors left uncovered each then plated make electrical contact with connector. stiffener bonded cable which provides mechanical stability exposed copper conductors during mating unmating. This type cable used when straight one-to-one connection required.

CONTACT DESIGN
keeping pace with FFC/FPC Technology, Elco developed different contact geometrics guarantee reliable tight connections. standard contact, which available series, designed mate with copper based FFC/FPC. This initial

contact system proved damaging softer carbon silver paste. 1985, Elco introduced first contact specifically designed this application. Incorporating radiused point, this contact provides reliability needed meet today's mechanical environmental environments.

CONNECTOR TERMINOLOGY
(Zero Insertion Force) This connector style allows highest possible number mating cycles (30) FFC/FPC. This connector incorporates mechanical slider mechanism which snaps down over cable after inserted into insulator body. (Low Insertion Force) This style most cost effective FFC/FPC connector while still providing reliability. prepared cable gently pressed into insulator slot. There moving parts, however, maximum durability mating cycles.

CONTACT ORIENTATION
Dual Sided Contacts (LIF Only): Cable orientation critical. Single Sided Contacts (Includes Bottom): This style requires FFC/FPC inserted into insulator where exposed copper matches with contact.
Choosing correct connector eliminates flipping FFC/FPC 180°. EXAMPLES: Bottom Contact Contact 1.00mm 6200 6224 0.50mm 6210 6212 0.50mm 6222 6223
