SMD CONTACT INTRODUCTION 1. SCOPE. SMD CONTACT is high reliability product for electronic connection with the Component of Mobile devices such as Antenna, Ground, Hinge etc. 2. KEY FEATURES. Stable operation force and high reliability. Apply structure to protect Slip & Manhattan fault while SMD. Apply structure to reinforce side fillet & prevent solder climbing for secure hardness of PBA. Apply the STOPPER for prevention over pressure. Apply prevention glove jam structure in production line. Apply 3 contact point for strengthen contact force and convenience use. All cover LEAD / BFRs / HALOGEN / BERYLLIUM FREE. 3. APPLICATION. MOBILE PHONE,TABLETPC, PDA, UMPC, DIGITAL CAMERA, CAMCODER,PMP,WIBRO, GPS MODULE, NAVIGATION, MP3, UMPC, HOME, APPLIANCE, A/V EQUIPMENT ETC Widely applied in various electronic product.

NEW PRODUCT VE PRODUCT : NI BARRIER, SELECTIVE AU PLATING KEY FEATURES. PREVENTION OF SOLDER CLIMBING LOW CONTACT RESISTANCE. No antenna performance with Same contact register between full plating and partial plating. LOW PLATING COST( FULL PLATING Vs SELECTIVE PLATING : 10% REDUCED) Save cost as partial AU plating, Down the unit price 10% than full plating. PREVENTION OF SOLDER CLIMBING & SLIP.

PRODUCT STRUCTURE & FEATURES 1.High productivity with REEL TO REEL production.(reel TO REEL plating and packing.) -> WE produce more than 3billion pcs of shield can clip / dome switch by REEL TO REEL method 2. Cost merit with all internal production process. (Plating, PRESS, Packing) 3. Raw material is TITANIUM ALLOY so LEAD / BFRs / HALOGEN / BERYLLIUM FREE. 4.Minimizw contact register and prevent solder climbing by partial GOLD FLASH plating and plating point of contact -> Major MOBILE MAKER are choosing and will use. 5. High reliability guarantee more than 10,000times within operation distance change rate 20%. -> Carry out Dust test added life test. 6. Continuous VE activity for plating and structure improvement. 7. Continuous research and development small component to contribute slim mobile division. ( SHIELD CAN CLIP,SMD METAL DOME SWITCH,ANT CONTACT) -> Acquire competencies for sustainable development collaboration.

RELIABILITY List S P E C Contact resistance Contact repulsive power Life test Within 50mΩ. Measure it after move more than 50% of operate distance. Operation distance : 50% : min 80 gf / more than 80% 130gf. Contact height changing rate within 20% after move 10,000 times with maximum operating distance and 10 times per minute. Drop test Contact height changing rate within 20% drop height 50cm 500times or 150cm 12times when fixed the movement with maximum operation distance. Heat shock test High temp & humidity test Fixed maximum operation distance: -40 18HR -> +85 18HR operate 2 CYCLE (left it on room temp:1hr) : No corrosion and contact height changing rate should be within 20%. Fix after maximum operate distance left it 120HR as Temp:+85 / Humidity 85% condition. (Left it room temp 1HR) : No corrosion contact height changing rate must be within 20%. Salty water spray test Salt (NaCl) concentration : 5%, Spray pressure : 1.2kg/ cm2, Salty water temp: 35, left period : 72HR left it in room temp : No corrosion after leaving 1HR.
