Electronic component test equipment

Abstract

The invention provides electronic component test equipment, which comprises a feeding device, a receiving device, an environment control device, a test device, a moving device and a central control device. The moving device is used for taking electronic components to be tested from the feeding device and moving the electronic components to the environment control device through a material moving mechanism. The environment control device comprises at least one temporary placing area, a bearing mechanism, a temperature control mechanism and an anti-condensation mechanism. The bearing mechanism is arranged in the temporary placing area, and is used for allowing the material moving mechanism to place the electronic components to be tested with a bearer. The test device is used for taking out the pre-cooled electronic components to be tested from the bearer of the environment control device through a pickup mechanism, moving the electronic components to be tested to a test room, and placing the electronic components to be tested on a tester to carry out cold test work; and after cold test is finished, the material moving mechanism of the moving device moves the tested electronic components to the receiving device for collection. The environment control device is utilized to pre-cool the electronic components to be tested in a direct and forced manner, thereby reducing precooling work time, preventing condensation of the electronic components to ensure test qualified rate, and improving test production efficiency.

Description

technical field [0001] The invention relates to an electronic component testing equipment which can use an environmental control device to directly and forcibly pre-cool the electronic components to be tested to shorten the pre-cooling operation time, prevent condensation of the electronic components to ensure the test pass rate, and further improve the test production efficiency. Background technique [0002] Since some electronic components may be in a low-temperature environment during actual use, in order to ensure the quality of electronic components, the industry must conduct cold testing of electronic components with testing equipment after the electronic components are manufactured to eliminate defective products; please refer to figure 1 , is a schematic diagram of an electronic component testing device, which is equipped with a test device 12 and a delivery device 13 on the machine platform 11.

[0002] Since some electronic components may be in a low-temperature environment during actual use, in order to ensure the quality of electronic components, the industry must conduct cold testing of electronic components with testing equipment after the electronic components are manufactured to eliminate defective products; please refer to figure 1 , is a schematic diagram of an electronic component testing device, which is equipped with a test device 12 and a delivery device 13 on the machine platform 11. The test device 12 is provided with a test chamber 121, and the test chamber 121 is connected to the machine platform through a delivery pipeline 122 11 an external nitrogen gas supplier (not shown), the nitrogen gas supplier transports nitrogen gas to the test chamber 121 through the delivery pipeline 122, so that the inside of the test chamber 121 is gradually cooled to the required test temperature (-40 degrees) to form A low-temperature simulated working environment, a test circuit board 123 with a test seat 124 is configured in the test chamber 121 for testing electronic components, and the conveying device 13 uses the pick-and-place device 131 as the first, second, and third directions (such as X, Y, Z direction) displacement Put the electronic component 14 to be tested into the test seat 124 of the test device 12, the test seat 124 is to carry out the cold test operation to the electronic component 14 in the low temperature simulation operation environment of the test room 121, and the test is completed Afterwards, the pick-and-place device 131 of the delivery device 13 takes out the electronic component 14 that has been tested in the test chamber 121; yet, the temperature before the electronic component 14 to be tested is not placed in the test socket 124 is normal temperature, causing the electronic component 14 to be placed into the test socket 124. After the test seat 124, it is necessary to wait for the electronic components 14 to gradually cool down to the required test temperature (-40 degrees) in the test room 121 of the low-temperature simulation working environment before performing the cold test operation, which not only consumes nitrogen but also increases the cost. Also increase the cold test operation time

[0003] Therefore, see figure 2 , then there is an industry to design a test equipment with a pre-cooling chamber, the test equipment is a pre-cooling chamber 152 is provided on the side of the testing chamber 151, and the pre-cooling chamber 152 is provided with a tray 153 to hold the electronic components 14 to be tested. In the pre-cooling chamber 152, there is a delivery pipeline 154 communicating with nitrogen gas, so that the nitrogen gas can be injected into the pre-cooling chamber 152 by using the delivery pipeline 154, so that the pre-cooling chamber 152 can form a low-temperature environment, and then the electronic components 14 to be tested can be lowered in advance. temperature, so that the electronic component 14 to be tested can be quickly carried out the cold test operation when it is transferred to the test chamber 151; yet, this test equipment uses the delivery pipe 154 to inject nitrogen into the pre-cooling chamber 152 to flow, and the pre-cooling chamber 152 is first After forming a low-temperature environment, the temperature of the electronic components 14 in the pre-cooling chamber 152 can be indirectly lowered gradually, which not only takes a long time for the pre-cooling operation, but also costs money.
