Description
Technical field
The invention belongs to field of semiconductor devices, be specifically related to a kind of assembly for the fixed crystal pipe.
Background technology
Existing transistorized fixed structure comprises transistor pressing plate and printed circuit board (pcb), fixation principle is: after the transistor mount bending, 2 slightly larger in diameter are inserted the transistor fixing hole in the transistor alignment pin of transistor fixing hole, fluting in the middle of the alignment pin, utilize the elasticity of plastics, become " spring pivot " structure, when transistor can prop up transistor down the time, it is not dropped, then utilize the M4 screw with transistor pressing plate and transistor as black box be fixed on the printed circuit board (pcb), this " PCB+ transistor pressing plate " assembly, be placed on the radiator, lay down the M4 screw, utilize the M3 screw that the transistor pressing plate is fixed on the radiator, thereby compress transistor in spreader surface.
This kind fixed structure, its mounting process has major defect in practice:
1.M4 2 actions need be installed and lay down to screw, wastes time and energy;
2. the transistor laminate material is thermoplastics, and the transistor alignment pin is the enough elasticity in the imagination not, and when the transistor transistor that is unable to hold out down the time, transistor drops.In the execute-in-place, the workman signs by getting stuck between the teeth in PCB transistor mount via hole and props up transistor it is not dropped, and wastes time and energy, and is a kind of damage to pin.
