Description
Technical Field
The invention relates to an electronic element crimping unit and a testing device applied by the same, which can change the crimping force and the displacement speed of a crimper so as to meet the testing operation requirements of various types of electronic elements and achieve the purposes of ensuring the testing quality, improving the use efficiency of equipment and saving the equipment cost.
Background
Nowadays, electronic devices (such as IC with solder balls) are classified into different types such as logic IC, memory IC, analog IC and micro-device IC, and the positions and the number of the solder balls of the different types of electronic devices are different, but no matter what type of electronic devices, the test operation must be performed on the test equipment to eliminate the defective products and ensure the product quality.
Referring to fig. 1 and 2, in the conventional testing apparatus, a testing device 10 and a pressing unit 11 are mainly disposed on a machine; the testing device 10 is provided with a plurality of testing sockets 102 on a testing circuit board 101, a plurality of probes 103 are arranged in each testing socket 102, and springs 104 are respectively arranged below each probe 103 to make each probe 103 elastically telescopic; the pressing unit 11 can drive the displacement to the upper part of the testing device 10, the pressing unit 11 is provided with a pressing device 111 driven by a driving mechanism to move in a first direction (such as Z direction), the bottom of the pressing device 111 is respectively provided with a lower pressing head which can be a suction nozzle at the position corresponding to each testing socket 102 so as to simultaneously take and place a plurality of electronic components 20, wherein the driving mechanism is provided with a motor 112, the output shaft of the motor 112 is connected with a lead screw 114 through a pulley set 113, the pressing device 111 is screwed on the lead screw 114 through a screw sleeve, so that the motor 112 can drive the lead screw 114 to rotate through the pulley set 113, and then the lead screw 114 drives the pressing device 111 to move up and down; referring to fig. 3 and 4, when the pressing unit 11 moves the plurality of electronic devices 20 to the upper side of the testing apparatus 10 during the testing operation, which uses a motor 112 to drive a pulley set 113, and drives the lead screw 114 to rotate through the pulley set 113, the pressing device 111 is driven to perform a pressing displacement in a first direction (such as Z direction), and each electronic component 20 is placed into the corresponding test socket 102, the solder balls 201 of the electronic components 20 are brought into contact with the probes 103 in the test sockets 102, in order to ensure that each solder ball 201 of the electronic device 20 reliably contacts each probe 103 in the test socket 102 to ensure the test quality, continuously pressing down each electronic device 20 for a suitable distance to ensure that each solder ball 201 of the electronic device 20 contacts each probe 103 in the test socket 102, so as to simultaneously execute the test operation of plural electronic devices 20; when the presser 111 presses the electronic component 20, in order to make each probe 103 pressed by each solder ball 201 of the electronic component 20 to compress the spring 104, the motor 112 of the driving mechanism must be able to output enough torque force to make the pressing force of the presser 111 enough overcome the reaction force generated by all the springs 104, so as to ensure that each solder ball 201 of the electronic component 20 is in contact with each probe 103 in the test socket 102, therefore, when the motor 112 is selected and configured, the rotation speed output by the motor 112 must be considered to make the presser 111 quickly move up and down to improve the operation efficiency, the torque force output by the motor 112 must be considered to make the pressing force of the presser 111 enough overcome the reaction force generated by all the springs 104, and the proper motor 112 is selected and configured under the double consideration of the rotation speed and the torque force; however, because the types of electronic components are various and the positions and the number of the solder balls of different types of electronic components are different, when the machine platform executes the test operation of other different types of electronic components, if the number of the solder balls of the electronic components executing the test operation is less, other corresponding test devices can be replaced on the machine platform, because the number of the probes and the springs in each test socket is reduced corresponding to the number of the solder balls of the type of electronic components, and correspondingly, the reaction force generated by all the springs is reduced, the downward force generated by the motor 112 driving the pressure extractor 111 can still overcome the reaction force generated by all the springs, and the test operation can be executed; however, when the number of the solder balls of the electronic component executing the testing operation is large, another corresponding testing device is replaced on the machine table, and because the number of the probes and the springs in each testing socket of the testing device is increased corresponding to the number of the solder balls of the electronic component, correspondingly, the reaction force generated by all the springs is increased, and the situation that the downward force generated by the motor 112 driving the press-fetching device 111 cannot overcome the reaction force generated by all the springs may occur, the press-fetching device 111 is difficult to continuously press down each probe to compress each spring, and each solder ball of the electronic component cannot be ensured to contact each probe in the testing socket, thereby affecting the testing quality.
In order to solve the above disadvantages, although a motor with larger output torque force can be installed on the machine platform to meet the testing operation requirements of various electronic components, the motor with larger output torque force has higher cost and larger volume, which is not beneficial to space configuration, and the motor with larger output torque force has slower output rotation speed, which relatively slows down the speed of the motor driving the pressure extractor to move up and down, thereby affecting the overall testing operation efficiency; therefore, under the dual consideration of the test operation requirements and the test operation efficiency of various electronic components, various test equipment with different output torque motors must be purchased, and the test operation is performed on the different test equipment according to the test operation requirements of various electronic components, which not only reduces the use efficiency of each test equipment, but also greatly increases the equipment cost.
