Detection system and detection method

The invention relates to a detection system and a detection method, in particular to a detection system and a detection method for batch test electronic components.

With the advancement of technology, electronic products are everywhere in daily life and are increasingly diversified. Although the functions and application fields of various electronic products are different, in order to make the system operate smoothly, related necessary components include: a processor, a storage unit, and an electrical connector. Among them, due to the rapid development of process technology, the size of electronic components is getting smaller. To ensure the yield, electronic components are usually tested before leaving the factory or assembled to ensure the yield of electronic products.

Taking a storage unit as an example, according to different technologies and structure classifications, including: dynamic random access memory (DRAM), flash memory, solid state disk (SSD) )Wait. When detecting for a storage unit, as the storage capacity increases, it is conceivable that the detection time will also increase.

Conventional detection systems can be operated simultaneously using multiple test devices. As shown in FIG. 1, the conventional detection system 10 includes four test devices 111, 112, 113, 114, wherein the test devices 111, 112 share one robot arm 131, and the test devices 113, 114 share another robot arm. 132. A plurality of components 14 to be tested are placed on the carrier 15 for backup. The robot arm 16 grabs the ready carrier 15 and places it on the conveying devices 171 and 172. The conveying devices 171 and 172 can respectively be disposed on the conveying rails 181 and 182. The carrier disk 15 accommodating the device under test 14 is fed into the detection system 10, or the device under test 14 is detected by the detection system 10, and is removed from the detection system 10 with the carrier disk 19.

More specifically, when the carrier 15 carrying the device under test 14 is fed into the detection system 10, the robot arms 131, 132 are repeatedly oscillated back and forth, and the components 14 to be tested are sequentially placed on the testing devices 111, 112, 113. , 114. Each of the devices 14 to be tested has electrical contacts (not shown), and the test devices 111, 112, 113, 114 have a circuit board and a plurality of probes (not shown), when the electrical contacts of the components 14 to be tested are The probe contacts on the test devices 111, 112, 113, 114 will be electrically connectable to the circuit board. In order to ensure contact, it is common practice to place the device under test 14 and fill the test devices 111, 112, 113, 114, and then press down with a platen to ensure electrical connection to the test devices 111, 112, 113, 114. All the components 14 to be tested are tested simultaneously.

However, in the conventional detection system 10, the test devices 111, 112, 113, 114 must wait for the mechanical arms 131, 132 to gradually configure the device under test 14 to perform the detection operation, and the test devices 111, 112, 113, 114 is in an idle state; once the test devices 111, 112, 113, 114 can enter the detection procedure, the robot arms 131, 132 are now in an idle state. As mentioned above, as the storage capacity increases, the detection time will also increase, and the idle time of the robot arms 131, 132 will be more. Since the detection equipment is expensive (the price of the robot arm is even higher than that of the test device itself), if the equipment is often idle, the detection efficiency is lowered and the cost is increased.

The conventional detection system 10 may consider increasing the number of test devices to increase the total output of the overall system. However, the size of the test device is large, and the number of robot arms must also be increased at the same time, which is only to expand the scale of the detection system. For work efficiency and cost issues, it still cannot be effectively solved.

In view of this, it is an urgent problem to be solved in the industry to provide a detection system and a detection method with high efficiency and batch concept.

Specifically, the present invention directly feeds the carrier tray carrying the device to be tested into the test device, and then electrically connects and detects the device. In the conventional detection system, the component to be tested must be sequentially dependent on the robot arm. The way it is assigned to the test device. After the detection process is completed, the carrier tray can be removed and then transferred to another carrier tray, and the operation is repeated, so that the test device can greatly reduce the idle time for allocating the components to be tested, so that the hourly capacity of each test device ( Units per hour, UPH) maximize.

Another object of the present invention is to provide a detection system and a detection method.

The carrier tray filled with the component to be tested will be placed in the inlet area of the conveying section, and the carrier tray will be transported to an idle testing device for detection according to the condition of each testing device.

In the detection system of the present invention, the working efficiency of the visual distribution mechanism is correspondingly configured with an appropriate number of test devices. In this way, both the test device and the distribution mechanism can avoid being idle, and are in a state of being close to full capacity.

Conceivably, the detection efficiency can be improved and the cost can be reduced.

Another object of the present invention is to provide a detection system and a detection method.
