Description

Technical Field

[0001] This invention relates to a joining mechanism that can perform dense multi-zone micro-area heat exchange to improve temperature control efficiency. Background Technology

[0002] Currently, operating devices use mechanisms such as bonding mechanisms, testing mechanisms, preset temperature mechanisms, or conveying mechanisms to perform preset and temperature-controlled operations on electronic components. Taking cold testing as an example, the testing mechanism uses a tester to hold and test the electronic component. A bonding mechanism is located above the tester. The bonding mechanism has a bonding surface to press the electronic component, and has a single flow channel inside. One end of the flow channel has an inlet for injecting refrigerant, and the refrigerant flows towards the outlet at the other end of the flow channel. This is intended to press the electronic component of the tester at a preset test temperature, so that the electronic component is subjected to a temperature environment that simulates its future use, thus performing cold testing.

[0003] However, although the fitting fixture can initially have a preset test temperature on the side of the fitting surface relative to the inlet due to the coolant being introduced at a preset low temperature at the inlet of the flow channel, the coolant will gradually heat up as it flows through the fitting surface and electronic components through heat exchange. As the coolant flows closer to the outlet of the flow channel, it cannot maintain the preset low temperature. Consequently, the side of the fitting surface relative to the outlet cannot maintain the preset low temperature, resulting in a temperature difference between the two sides of the fitting surface. This makes it impossible to uniformly control the temperature of the electronic components, thereby affecting the test quality of the electronic components. Summary of the Invention

[0054] As mentioned above, the branch channel 132 of the supply unit is located to the side of the inlet branch channel 133, and the branch channel 132 and the inlet branch channel 133 are configured in different directions.

[0055] As mentioned above, the supply unit is provided with a plurality of discharge branch channels 133, and the plurality of discharge branch channels 133 are connected to the branch channel 132.

[0056] In this embodiment, the supply unit is provided with an inlet main channel 131, a plurality of branch channels 132, and a plurality of outlet branch channels 133. Furthermore, the inlet main channel 131 is located on the first component 11 and includes at least one first main inlet port 1311, a plurality of main inlet sections 1312, and a plurality of second main inlet ports 1313. The first main inlet port 1311 connects to the water inlet pipe 134 and the plurality of main inlet sections 1312, enabling the water inlet pipe 134 to allow fluid at a preset temperature (e.g., refrigerant or water with a preset low temperature) to flow into the plurality of main inlet sections 1312.

The flow channel 132 is arranged in the Y direction on the second component 12 and is connected to the second main inlet 1313 by the plurality of branch inlets 1321, so that the fluid at a preset temperature of the main inlet channel 131 flows into the branch channel 132, which helps to increase the flow rate of the inflowing fluid and shorten the time for the fluid to flow into the plurality of branch inlets 133. The plurality of branch inlets 133 are arranged in the X direction on the second component 12, and are configured in a different direction from the branch channel 132, but are connected to the branch channel 132. The branch channel 132 can evenly distribute the fluid at the preset temperature to the plurality of inlet channels 133.

[0057] The microchannel unit has a plurality of microchannels in the area of ​​the connector and close to the connector surface 121. The plurality of microchannels allow the inlet channel 133 to flow in fluid at a preset temperature, and to perform dense multi-zone micro-area heat exchange with the connector surface 121, so that the connector surface 121 is at a uniform temperature.

[0058] As described above, the microchannel unit has a communicating inlet 141, at least one microchannel 142, and an outlet 143. The inlet 141 communicates with the inlet channel 133 and the at least one microchannel 142, allowing fluid at a preset temperature to flow in. The outlet 143 communicates with the at least one microchannel 142 and the outlet channel, allowing the heat-exchanged fluid to flow out. Furthermore, the inlet 141 and outlet 143 of the microchannel have a height difference from the microchannel 142.

[0059] In this embodiment, a microchannel unit is disposed on the second component 12 of the connector, and a plurality of rows of microchannels are evenly distributed in the area near the joint surface 121. Each row has a plurality of microchannels. The inlet 141 of each microchannel has a diameter of 0.2 mm. One end of the inlet is connected to the inlet branch channel 133 of the supply unit, and the other end is connected downward along the Z direction to a microchannel section 142 arranged in the Y direction. This allows fluid at a preset temperature in the inlet branch channel 133 to flow into the microchannel section 142, so that the fluid and the joint surface 121 can perform micro-area heat exchange. The microchannel section 142 is connected upward along the Z direction to the outlet 143. The outlet 1552 has a diameter of 0.2 mm and supplies the heat-exchanged fluid.

[0060] The unit is provided with at least one main outlet channel 151, at least one manifold channel 152 and at least one branch outlet channel 153. The branch outlet channel 153 allows multiple microchannels to flow into the heat-exchanged fluid and to converge the heat-exchanged fluid into the manifold channel 152. The manifold channel 152 can converge the heat-exchanged fluid into the main outlet channel 151 for output.

[0061] As mentioned above, the confluence channel 152 of the given unit is located to the side of the outflow channel 153, and the confluence channel 152 and the outflow channel 153 are configured in different directions.

[0062] As mentioned above, the unit is provided with a plurality of discharge branch channels 153, and the plurality of discharge branch channels 153 are connected to a confluence channel 152.

[0063] In this embodiment, the unit is provided with an outflow main channel 151, a plurality of confluence channels 152 and a plurality of outflow branch channels 153. Furthermore, the outflow main channel 151 is disposed on the first component 11 and includes at least one first main outflow port 1511, a plurality of main outflow sections 1512 and a plurality of second main outflow ports 1513. A plurality of discharge branch channels 153 are arranged in the X direction on the second component 12, while the connecting channel 152 is arranged in different directions. The plurality of discharge branch channels 153 can collect the heat-exchanged fluid into the channel 152. The plurality of channel 152 are arranged in the Y direction on the second component 12 and are connected to a plurality of second main outlets 1513 through a plurality of outlets 1521, so that the heat-exchanged fluid in the channel 152 can flow out to the main outlet section 1512. The main outlet section 1512 of the main outlet channel 151 is connected to the water outlet pipe 154 through the first main outlet 1511, so that the heat-exchanged fluid flows into the water outlet pipe 154 and is output.

[0064] Depending on the operational requirements, the joining mechanism further includes at least one heating element 16, which is assembled to the joining fixture and can raise and regulate the temperature of the joining fixture. For example, the heating element 16 may be provided between the first component 11 and the second component 12, or inside the second component 12, or on the joining surface 121; these are not limited to this embodiment. In this embodiment, the joining mechanism provides a heating element 16 inside the second component 12.

[0065] Please see Figure 1 , Figures 6 to 9 The working device 10 of the present invention includes at least one joining mechanism and at least one mounting mechanism; the at least one joining mechanism includes a coupling tool, a supply unit, a microchannel unit, and a dispensing unit; the at least one mounting mechanism is provided with at least one mounting device for mounting the at least one joining mechanism. Furthermore, the mounting device of the mounting mechanism can be fixed or movable; for example, the mounting device can be a frame or a fixed base for fixed assembly of the joining mechanism; for example, the mounting device can be a transfer arm or a movable base that can move in at least one direction to drive the joining mechanism to move. In this embodiment, the mounting device is a transfer arm 21, driven by a drive source (not shown) to move in the Z direction, and the transfer arm 21 is mounted on the bearing surface 111 of the first component 11 of the coupling tool. Depending on the operational requirements, the working device 10 further includes at least one testing mechanism, which is provided with at least one tester 22 for testing electronic components. In this embodiment, the tester 22 is provided with an electrically connected circuit board and a test socket for holding and testing electronic components 31. The transfer arm 21 can drive the first component 11, the second component 12, the supply unit, the microchannel unit and the output unit of the bonding mechanism to move in the Z direction toward the tester 22, so that the bonding surface 121 of the bonding fixture presses against the electronic component 31.

[0066] Depending on the operational requirements, a floating device (not shown in the figure) can be installed between the mounting surface 111 and the bracket to allow the coupling to float and buffer displacement, which is also acceptable.

[0067] In the cold testing operation, the water inlet pipe 134 of the supply unit of the connecting mechanism delivers a refrigerant fluid through the first main inlet 1311 of the main inlet channel 131 to a plurality of main inlet sections 1312. Each main inlet section 1312 flows rapidly to the branch channel 132 through a plurality of second main inlets 1313 and a branch inlet 1321. Since the branch channel 132 is connected to a plurality of branch channels 133, the refrigerant in the branch channel 132 can be rapidly and evenly distributed to the plurality of branch channels 133, keeping the refrigerant in the plurality of branch channels 133 at a preset low temperature; the branch channels 133 are... Multiple microchannels are connected to an inlet 141, each inlet 141 allowing refrigerant to flow from top to bottom into a microchannel section 142. The microchannel section 142 is close to the junction surface 121. With the design of multiple short-path microchannels arranged in a dense multi-zone array above the junction surface 121 and reducing channel temperature loss, the refrigerant in the microchannel section 142 of the multiple microchannels can quickly exchange heat with the junction surface 121 at a preset low temperature. The junction surface 121 is in a state of overall uniform temperature, thereby effectively controlling the electronic components 31 in the temperature control tester 22 to perform cold testing in a preset low temperature environment, thereby improving the test yield.

[0068] The refrigerant that has undergone heat exchange in the micro-segments 142 of the plurality of microchannels flows from bottom to top towards the outlet 143 to the plurality of branch channels 153 of the unit. Since the manifold 152 covers the plurality of branch channels 153, the plurality of branch channels 153 quickly collect and transport the heat-exchanged refrigerant to the manifold 152. The manifold 152 then transports the heat-exchanged refrigerant from the manifold outlet 1521 to the second main outlet 1513 of the main outlet channel 151. The second main outlet 1513 transports the heat-exchanged refrigerant to the outlet pipe 154 for output via the main outlet segment 1512 and the first main outlet 1511, thereby facilitating the rapid circulation of the refrigerant and improving the temperature control efficiency.
