SMD Wafer Loading Ultrasonic Cleaning Machine

SMD stands for Surface Mount Device, which is a type of SMT component. In the early stages of electronic circuit board production, through-hole assembly was entirely done by hand. After the first automated machines were introduced, they could place some simple pin components, but complex components still required manual placement before reflow soldering. Surface mount components mainly include rectangular chip components, cylindrical chip components, composite chip components, and irregularly shaped chip components.

In this industry, visual inspection is required in the processing workshop, using the naked eye or a magnifying glass to check whether the solder ends or pin surfaces of components are oxidized or contaminated. Additionally, under a 20x microscope, the solder wetting condition is inspected, requiring over 90% of the component solder ends to be wetted. Finally, for products requiring cleaning, the markings on the components should not fall off after cleaning, and the performance and reliability of the components should not be affected (visual inspection after cleaning).

The VGT-609FTA by Weigute is an SMD ultrasonic cleaning machine. The equipment has a total of 6 functional tanks (including loading and unloading systems) and is equipped with a circulation filtration system, touchscreen system, agitation system, spray system, ultrasonic cleaning system, timing system, lever-type robotic arm system, visual glass system, stainless steel outer enclosure system, Teflon pipeline system, and more. The equipment uses cleaning agents for washing, pure water for rinsing, and a robotic arm to complete the transfer between processes. It features automatic loading and unloading systems, easily achieving full-machine functionality.

During the cleaning process, the workpiece is subjected to the impact of the "cavitation phenomenon" generated by high-frequency ultrasound and the system's continuous up-and-down motion, which increases liquid friction, allowing contaminants on the workpiece surface to quickly detach and achieving high cleanliness.

VGT-609FTA SMD Ultrasonic Cleaning Machine by Weigute Features an Advantageous Structural Composition:

I. Hot Pure Water Spray Rinsing Tank:

1. The tank body is a four-sided overflow tank;

2. Drainage setting: After rinsing, the tank can be instantly emptied;

3. Bottom conical drainage outlet with a manual valve for tank cleaning;

4. Each tank is equipped with a drainage valve at the bottom and can be fully drained, with the drainage height suitable for placing packaging barrels;

5. Independent agitation outside the tank;

6. Equipped with a spray system and curtain-style flushing. The left tank has five layers, with the top layer flushing hooks, and the right tank has four layers; flushed water is directly discharged;

7. Equipped with a demisting device;

8. Flow rate control: 5-12L/M, with a flow meter for monitoring;

9. Heating function with a heating power of 3KW;

10. Water temperature at 55°C, with self-heating, a liquid storage tank, and a thermometer to monitor water temperature;

11. The top pipe is 8mm, while all others are 10mm.

II. Liquid Storage Tank Structure:

1. Divided into two chambers by a partition; the cleaned solution after oil separation is pumped back into the cleaning tank by a circulation pump, achieving self-circulation and improving solution utilization, while the separated oil is discharged into the main drain pipe;

2. Equipped with a cooling water pipe;

3. Lower liquid level switch; when the water level is low, an automatic audio-visual alarm is triggered, with alarms connected in series.

III. Noise Reduction System:

1. While ensuring no impact on ultrasonic effectiveness, the ultrasonic noise is controlled within a certain range as much as possible, effectively improving employee work efficiency;

2. An exhaust system is added to the top of the equipment to prevent mist accumulation and dripping into the tank, which could contaminate the wafers.

IV. Inductive Loading and Unloading Platform Structure:

1. Cylinder-driven positioning blocks for loading and unloading;

2. The unloading station is equipped with a water collection tray and automatic drainage;

3. The unloading station has a spray device for manual part retrieval;

4. PLC-controlled, coordinated with the robotic arm for automatic feeding.

V. Agitation Mechanism:

1. Shares a power source with the robotic arm servo motor, driving linear sliders for up-and-down motion, fundamentally ensuring continuous agitation, reducing frictional resistance, and preventing damage to the agitation system due to heavy workpieces, thereby enabling the agitation frame to drive the cleaning basket in up-and-down motion within the cleaning tank;

2. Stable operation model with low noise;

3. Materials are effectively corrosion-resistant;

4. During cleaning, the workpiece undergoes uniform agitation, increasing friction between the workpiece and the liquid, facilitating rapid detachment of surface contaminants and improving cleaning effectiveness.
