[0002] Semiconductor components are electronic devices made of semiconductor materials (such as silicon and germanium). Semiconductor materials possess conductivity between that of conductors and insulators, and various electronic functions can be achieved by controlling their conductivity. Semiconductor components are widely used in modern electronic technology, becoming a core component of electronic devices and systems. During the semiconductor manufacturing process, components are soldered together. To remove solder residue from the solder surface, they need to be cleaned using a cleaning solution and an ultrasonic cleaner.
[0003] During the cleaning process, organic solvents such as chloroform and dichloromethane are used as cleaning agents, which have a good cleaning effect on welding slag. These organic solvents are volatile during the cleaning process and are usually collected by condensation for recycling. However, in addition to organic cleaning agents, water vapor from the air also adheres to the condenser. When water vapor mixes with the cleaning agent, it will contaminate the semiconductor devices being cleaned, which is very detrimental to the product yield and reliability.

[0029] like Figure 1-8 As shown, a separation device in this embodiment includes a housing 1 and an input pipe 2. The input end of the input pipe 2 is connected to the condensation system of the cleaning machine, and the output end of the input pipe 2 is connected to the housing 1. The housing 1 is connected to a drain pipe 3 and a recovery pipe 4. The drain pipe 3 is used to drain water from the mixture, and the recovery pipe 4 is used to drain cleaning agent from the mixture. The two ends of the drain pipe 3 are distributed vertically, and the drain pipe 3 is fixed and sealed through the bottom of the housing 1. The upper end of the drain pipe 3 is located inside the housing 1. The two ends of the recovery pipe 4 are distributed vertically, and the recovery pipe 4 is fixed and sealed through one side of the housing 1. The upper end of the recovery pipe 4 is located inside the housing 1. The upper ends of the drain pipe 3, the upper ends of the recovery pipe 4, and the input end of the input pipe 2 are distributed sequentially from top to bottom.
[0030] During use, the water and cleaning agent mixture generated by the condensation system of the cleaning machine is transported to the housing 1 through the input pipe 2. Due to the different densities, the mixture in the housing 1 forms a water layer and a cleaning agent layer distributed vertically. At this time, the upper end of the drain pipe 3 is located in the water layer, while the upper end of the recovery pipe 4 is located in the cleaning agent layer. Then, the water is discharged from the drain pipe 3, and the cleaning agent is discharged from the recovery pipe 4. It should be noted that during the discharge of water and cleaning agent, the mixture is still input through the input pipe 2, so that the upper end of the drain pipe 3 is always located in the water layer, and the upper end of the recovery pipe 4 is always located in the cleaning agent layer. In this way, the cleaning agent and water are separated.
[0031] The bottom of the box 1 is provided with a discharge pipe 5. Valves are provided on the discharge pipe 5, drain pipe 3 and recovery pipe 4. During the period when the input pipe 2 inputs the mixed liquid into the empty box 1, all valves are in the closed state. When the upper end of the drain pipe 3 is in the water layer and the upper end of the recovery pipe 4 is in the cleaning agent layer, the valves on the drain pipe 3 and the recovery pipe 4 are opened. When the use is finished, the valve on the discharge pipe 5 can be opened to discharge the remaining mixed liquid in the box 1.
[0032] The drain pipe 3 includes a fixed section 301 and a telescopic section 302. The fixed section 301 and the telescopic section 302 are arranged coaxially. The fixed section 301 is sealed and passes through the bottom of the box 1. The telescopic section 302 is located inside the box 1. The lower end of the telescopic section 302 slides and is sealed on the upper end of the fixed section 301. The telescopic section 302 and the fixed section 301 are locked together by a locking component, namely a screw 303. When the screw 303 is loosened, the telescopic section 302 can move up and down on the fixed section 301. After the telescopic section 302 has moved, the screw 303 is tightened to fix the telescopic section 302 and the fixed section 301. In this way, the position of the upper end of the drain pipe 3 can be adjusted so that the height of the upper end of the drain pipe 3 can be adjusted according to the proportion of water in the mixture, and the distance between the upper end of the drain pipe 3 and the cleaning agent layer is too small, so that the cleaning agent will accidentally enter the drain pipe 3.
[0033] A control component is provided on the recovery pipe 4. The control component is used to adjust the discharge speed of the cleaning agent from the recovery pipe 4. In this way, the drainage speed of the drain pipe 3 and the discharge speed of the cleaning agent from the recovery pipe 4 are consistent with the ratio of water and cleaning agent in the mixture. This ensures that the boundary between the water layer and the cleaning agent layer in the tank 1 is always at the same height, and prevents the cleaning agent from being accidentally discharged from the drain pipe 3 after the height of the boundary between the water layer and the cleaning agent layer in the tank 1 changes.
[0034] The control component includes a sealing plate 6, which is sealed and fixedly connected to the upper end of the recovery pipe 4. The sealing plate 6 is provided with a first through hole 7. A rotating shaft 8 passes through the sealing plate 6 and is perpendicular to the sealing plate 6. The rotating shaft 8 and the sealing plate 6 are rotatable and sealed together. A rotating disk 9 is fixedly provided at one end of the rotating shaft 8 and a knob 10 is fixedly provided at the other end of the rotating shaft 8. The rotating disk 9 is located inside the recovery pipe 4 and is sealed and fitted with the sealing plate 6. The knob 10 is fitted with the sealing plate 6. A second through hole 11 is provided on the rotating disk 9 and is arranged opposite to the first through hole 7.
[0035] Multiple first through holes 7 and multiple second through holes 11 are provided. The multiple first through holes 7 are evenly distributed circumferentially around the rotating shaft 8, and the multiple second through holes 11 correspond one-to-one with the multiple first through holes 7.
[0036] The specific number of the first through holes 7 is eight;
[0037] The diameter of the first through hole 7 is equal to the diameter of the second through hole 11;
[0038] The cleaning agent passes through the first through hole 7 and the second through hole 11 in sequence and enters the recovery pipe 4. When it is necessary to adjust the discharge speed of the cleaning agent, turn the knob 10 to make the rotating shaft 8 drive the rotating disk 9 to rotate, so that the diameter of the cleaning agent entering the second through hole 11 in the first through hole 7 is reduced, thus realizing the discharge speed of the cleaning agent.
[0039] The housing 1 is made of stainless steel. Since the cleaning agent is corrosive, the stainless steel housing 1 can improve the corrosion resistance. In fact, all parts of the device are made of stainless steel.
[0040] In summary, by setting drain pipes 3 and recovery pipes 4 at different heights, the water and cleaning agent in the mixture are discharged separately, thus achieving separation of cleaning agent and water. Secondly, by adjusting the height of the telescopic section 302, the distance between the upper end of the drain pipe 3 and the cleaning agent layer is prevented from being too small, which could cause the cleaning agent to accidentally enter the drain pipe 3. In addition, by adjusting the speed at which the cleaning agent is discharged from the recovery pipe 4, the boundary between the water layer and the cleaning agent layer in the tank 1 is always kept at the same height, preventing the cleaning agent from being accidentally discharged from the drain pipe 3 if the height of the boundary between the water layer and the cleaning agent layer in the tank 1 changes.
[0041] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
