Abstract
Description
Technical Field
[0001] The present application relates to the technical field of semiconductor chip testing, and in particular to a high-density connector structure and testing equipment supporting semiconductor testing. Background Art
[0002] Wafer testing is between wafer manufacturing and packaging in the entire chip production process. After wafer production is completed, thousands of unpackaged chips are regularly distributed throughout the wafer. Since dicing and packaging have not yet been performed, the pins of the chips are all exposed. These extremely tiny pins need to be connected to the test machine through finer probes.
[0003] In most cases at present, the probes used in wafer testing are still cantilever probes. The cantilever probes are relatively long and suspended in the air, which makes it very difficult to control signal integrity and the test rate is relatively low, generally 100-400Mbps, making it very difficult to test high-speed data signals. In addition, the direct contact between the probe and the pad also has limitations in electrical characteristics, which can easily cause electrical leakage and loop resistance, and will also have a great impact on the accurate measurement of high-precision data signals.
[0004] The equipment commonly used in wafer testing includes testers, probe stations, and the interface between the testers and probe stations. Finished product testing is the last interception before the chip leaves the factory. The test object is the packaged chip. After wafer testing, it will be packaged, and after packaging, finished product testing will be carried out. Finished product testing requires the use of testers, sorters, and the interfaces between the testers and sorters, Hi-fix and Socket.
[0005] With the development of advanced semiconductor manufacturing processes, the integration and speed of wafer testing and finished product testing are getting higher and higher, which poses higher challenges to test efficiency and test quantity. In existing solutions, the test machine and the object to be tested are mostly connected through spring pins, which are connected through elastic contact between the spring pins and the pads on the surface of the PCB board. In order to ensure that all spring pins are effectively in contact, the elastic pressure of the spring pins needs to be greater than a certain value, such as 30g / pin. In this way, the more spring pins there are, the greater the positive pressure or retention force required between the PCB board and the spring pins, which cannot meet the current increasingly high-density test requirements.
[0006] Moreover, with an increasing number of spring pins, it is impossible to ensure that all of them are reliably connected. In extreme cases, it is easy to cause damage or burn of the spring pins. In addition, the direct contact between the spring pins and the pads also has limitations in the characteristics of electrical equipment, which can easily cause leakage and loop resistance, which will also cause great harm to the precise measurement of high-precision data signals.

[0007] The embodiments of the present application provide a high-density connector structure and test equipment that support semiconductor testing, so as to solve the problem in the related art that the connection between the test machine and the object under test is mostly through spring pins. The more spring pins there are, the greater the positive pressure or holding force required between the PCB board and the spring pins, which cannot meet the current increasingly high-density testing requirements.

[0022] The beneficial effects of the technical solution provided by this application include:
[0023] The embodiment of the present application provides a high-density connector structure and testing equipment that support semiconductor testing. Since the high-density connector structure of the present application is provided with a board-end connector, the board-end connector includes a PCB board, and a plurality of first connectors fixed on the PCB board and arranged in a linear array or a circular array on the PCB board; a line-end connector, the line-end connector includes a second connector that is pluggable connected to the first connector, and the second connector is connected to a flat cable; at least two layers of contact springs connected to the first connector are provided in the slot of the second connector, and each layer of contact springs is pluggable connected to the first connector in a sequential order.
[0024] Therefore, the high-density connector structure of the present application has a plurality of first connectors arranged in a linear array or a circumference on the PCB board of the board-end connector, and a second connector connected to the first connector on the line-end connector, and a flat cable is connected to the second connector. The test signal is sent out through the signal test board in the test machine, and different test signal mapping sequences can be quickly matched by flexibly defining the arrangement of the flat cable of the line-end connector, and then docked through the first connector and the second connector, which greatly reduces the signal link loss of multiple links compared to the spring pin connection, and improves the signal integrity and reliability of the test machine.
[0025] The high-density connector structure of the present application has at least two layers of contact springs connected to the first plug-in connector in the slot of the second plug-in connector, and each layer of contact springs is plugged and unplugged with the first plug-in connector in a sequential order. When a plurality of first plug-ins and a plurality of second plug-ins are docked, it is avoided that all the contact springs of the second plug-ins contact the first plug-in connector at the same time, which reduces the contact resistance and friction, thereby realizing a low plug-in force structural connection, ensuring a small overall plug-in force when the whole machine interface is connected as a whole, and ensuring the reliability of the connection.
[0026] The line-end connector of the high-density connector structure of the present application also includes a fixing plate for fixing the second connector, and the second connector is arranged in a linear array or a circumferential array on the fixing plate; the second connector is provided with a mounting hole, and the clearance in the mounting hole is matched with a screw that fixes the second connector to the fixing plate. The notch of the second connector slot is provided with a chamfer or a rounded corner, and the plug of the first connector is provided with a conical guide head. When the first connector and several second connectors are docked, the second connector is adaptively aligned under the guidance of the conical guide head and the notch of the second connector slot. In actual application, it can ensure that up to 100-200 groups of first connectors and second connectors are accurately and reliably docked at the same time.
[0027] The line-end connector of the high-density connector structure of the present application also includes a third connector connected to the test machine. There are at least two third connectors, and each of the third connectors is connected to the second connector through a flat cable. The line-end connector is composed of a flat cable and a second connector and a third connector located at both ends of the flat cable. The second connector is used to connect with the first connector, and the third connector is used to connect with the test machine. There are at least two third connectors, and different test signals can be connected by adjusting the plugging position of the third connector and the test machine.
[0028] The side wall of the first connector of the high-density connector structure of the present application is provided with a riveting plate for fixing the first connector to the PCB board, and the riveting plate is provided with rivets for riveting the first connector to the PCB board. In practical applications, wafer testing and finished product testing both have harsh environmental tests at high or low temperatures, and traditional connectors are difficult to replace and maintain by welding or crimping. The first connector of the present application is installed with the PCB board by a rivet mechanical structure, which has a simple structure installation and strong replacement and maintainability.
[0029] The side wall of the first connector of the high-density connector structure of the present application is provided with a plurality of asymmetrically arranged riveted plates, and the riveted plates between two adjacent first connectors are arranged in a staggered manner along the length direction of the first connector. The area available for the first connector on the PCB is limited, and the riveted plates are designed to be arranged in an asymmetrical structure, which can ensure that all contact springs of the first connector are reliably electrically connected after the first connector is riveted; at the same time, a avoidance structure can be formed when the first connector is regularly arranged horizontally or vertically and arranged in a circle, and the area per unit area can increase the arrangement density of the first connector, effectively increasing the test density.

[0043] The embodiment of the present application provides a high-density connector structure that supports semiconductor testing, which can solve the problem in the related art that the test machine and the object under test are mostly connected through spring pins. The more spring pins there are, the greater the positive pressure or holding force required between the PCB board and the spring pins, which cannot meet the current increasingly high-density testing requirements.
[0044] See also Figures 1 to 3 As shown, an embodiment of the present application provides a high-density connector structure supporting semiconductor testing, including:

[0054] A second aspect of an embodiment of the present application provides a test device supporting semiconductor testing, wherein the test device includes a high-density connector structure supporting semiconductor testing as described in any of the above embodiments.
[0055] How it works
[0056] The embodiment of the present application provides a high-density connector structure and testing equipment that support semiconductor testing. Since the high-density connector structure of the present application is provided with a board-end connector 1, the board-end connector 1 includes a PCB board 12, and a plurality of first connectors 11 fixed on the PCB board 12 and arranged in a linear array or a circle on the PCB board 12; a line-end connector 2, the line-end connector 2 includes a second connector 22 that is plugged in and out of the first connector 11, and a flat cable 21 is connected to the second connector 22; at least two layers of contact springs 24 connected to the first connector 11 are provided in the slot of the second connector 22, and each layer of contact springs 24 is plugged in and out of the first connector 11 in a sequential order.
