Socket device for testing IC
Disclosed is a socket device for testing an IC, the socket device including: a base on which an integrated circuit (IC) is mounted; a contact module having multiple contacts; a floating hinge block elastically supported on a side of the base in a vertical direction; a lid configured to rotate with the floating hinge block and having a pressing portion on a bottom surface thereof; a floating latch elastically supported on a side of the base to be parallel to the floating hinge block such that the lid is fixed; a first camshaft installed by penetrating the base and the floating hinge block and adjusting a height of the floating hinge block; a second camshaft installed by penetrating the base and the floating latch and adjusting a height of the floating latch; a lever; a handle; and a link connected to the lever and the handle respectively to rotate independently.
1. A socket device for testing an integrated circuit (IC), the device comprising:
a base on which an IC is mounted;
a contact module provided on the base and having multiple contacts electrically connecting leads of the IC and leads of a printed circuit board (PCB);
a floating hinge block provided in a manner that being elastically supported on a side of the base in a vertical direction;
a lid configured to rotate with the floating hinge block and having a pressing portion on a bottom surface thereof, which is configured to protrude to press an upper surface of the IC;
a floating latch elastically supported on a side of the base to be parallel to the floating hinge block such that the lid is fixed;
a first camshaft installed by penetrating the base and the floating hinge block and adjusting a height of the floating hinge block according to a rotation angle;
a second camshaft installed by penetrating the base and the floating latch and adjusting a height of the floating latch according to a rotation angle;
a lever assembled with the first camshaft as one body and rotating;
a handle assembled with the second camshaft as one body and rotating;
a link in which both ends thereof are connected to the lever and the handle respectively to rotate independently.
2. The device of claim 1 , wherein each of the first camshaft and the second camshaft includes:
a first section having a circular cross section and rotatably assembled with the base; and
a second section extending from the first section, having a cam surface, which forms a plane in an axial direction on a part of an outer circumferential surface, and assembled with the floating hinge block and the floating latch individually.
3. The device of claim 2 , wherein each of the floating hinge block and the floating latch has an assembly hole through which the corresponding camshaft is inserted,
wherein the assembly hole has a plane in which surface contact is made with the corresponding cam surface.
4. The device of claim 1 , further comprising: multiple elastic members arranged in parallel between the floating latch and the base,
wherein the floating latch has a torque, which acts in a direction of engagement with the lid with respect to a rotation axis of the second camshaft.
5. The device of claim 4 , wherein the elastic members have different spring constants.
6. The device of claim 1 , wherein the pressing portion further includes a heating unit controlling temperature.
7. The device of claim 1 , wherein the contact module includes:
a fixed plate on which the multiple contact pins are disposed such that the fixed plate is fixed to the base; and
a floating plate which is elastically supported on the fixed plate to be spaced apart each other and through which a top end portion of the contact pins protrudes.
8. The device of claim 7 , wherein the floating plate is formed with a guiding surface, which is an inclined side surface thereof to guide a mounting position of the IC.
