The object of the present invention is achieved like this: a kind of SIM card encapsulating structure based on metal lead wire frame, described SIM card encapsulating structure comprises lead frame, chip, gold thread, plastic encapsulation body and carrier card, described lead frame is made by metal material, lead frame comprises pin and Ji Dao, chip places on the Ji Dao of lead frame, gold thread links to each other chip with pin, the plastic encapsulation body is all sealed the pin and the Ji Dao of chip and lead frame, constitute the SIM card module, described SIM card module is embedded carrier card, constitute SIM card.
The method for packing that the present invention is based on the SIM card encapsulating structure of metal lead wire frame comprises following processing step:
Step 1, by pre-designed structure, go out the lead frame that several are made up of Ji Dao and pin with metal material processing, each lead frame is made up of several relatively independent pieces, and each piece is the array arrangement by the identical unit of several separate again and forms
Step 2, flip-chip on the Ji Dao of lead frame, gold thread links to each other the pin of various chips and lead frame, makes the SIM card semi-finished product,
Step 3, with the SIM card semi-finished product that step 2 is made, all seal with the plastic encapsulation body, constitute the SIM card module group that connects together in array aggregate mode,
Step 4, by mode die-cut or cutting, the SIM card module component that step 3 is made is severed, making is the SIM card module group that array aggregate mode connects together originally, through becoming several independently SIM card modular units after the cutting,
Step 5, step 4 is made several independently the SIM card modular unit be embedded in the carrier card array mould plate,
Step 6, carry out laser printing or carry out personalisation process finishing the carrier card array mould plate that embeds the SIM card modular unit,
Step 7, the mode by cutting cut into the carrier card array mould plate of finishing printing the SIM card of the independent completion that can conveniently use.
The present invention is based on the SIM card encapsulating structure and the method for packing thereof of lead frame, compare, have following advantage with traditional soft structure SIM card that mounts:
1, the metal lead wire frame manufacture craft is simple, and cost is low, thereby greatly reduces the production cost of whole SIM card.
2, lead frame generally adopts metals such as Cu to make, than soft board hardness height, and load ball bonding efficient height.
3, the higher metal lead wire frame of hardness can carry the encapsulation of multicore sheet, has widened the functions expanding ability of SIM card.
4, adopt the SIM card module whole to embed convenient printing in the carrier card array.
5, lead frame adopts the Cu metal material, and electrical and thermal conductivity is good.
