在微电子器件向纳米级演进的今天，清洗工艺已成为决定产品良率的关键技术节点。全自动超声波清洗机凭借其独特的空化效应与智能控制技术，正在重塑精密电子元件的洁净度标准，实现了从微观层面呵护元件表面的技术突破。

　　In today's evolution of microelectronic devices towards the nanoscale, cleaning processes have become a key technological node determining product yield. The fully automatic ultrasonic cleaning machine, with its unique cavitation effect and intelligent control technology, is reshaping the cleanliness standards of precision electronic components, achieving a technological breakthrough in caring for component surfaces from a microscopic level.

　　超声波清洗的技术本质

　　The essence of ultrasonic cleaning technology

　　超声波清洗的核心在于液媒中的空化现象。当20kHz至100kHz的超声波在清洗液中传播时，会引发数以万计的微小气泡周期性膨胀与破裂。这种空化作用产生的高速微射流（可达100m/s）和局部高温高压（5000K，50MPa），能够高效剥离元件表面的有机污染物和微粒杂质。

　　The core of ultrasonic cleaning lies in the cavitation phenomenon in the liquid medium. When ultrasonic waves ranging from 20kHz to 100kHz propagate in the cleaning solution, they can cause tens of thousands of tiny bubbles to periodically expand and rupture. The high-speed microjet (up to 100m/s) and local high temperature and pressure (5000K, 50MPa) generated by this cavitation effect can efficiently remove organic pollutants and particulate impurities from the surface of the component.

　　全自动清洗机通过压电陶瓷换能器的阵列式布局，实现了声场能量的精准调控。每个换能器单元均可独立调节输出功率，在清洗腔内构建出三维动态声场。这种设计使声强分布均匀性突破95%，避免了传统设备因声场盲区导致的清洗残留。

　　The fully automatic cleaning machine achieves precise control of sound field energy through the array layout of piezoelectric ceramic transducers. Each transducer unit can independently adjust its output power, creating a three-dimensional dynamic sound field within the cleaning chamber. This design achieves a sound intensity distribution uniformity of over 95%, avoiding cleaning residues caused by blind spots in traditional equipment.

　　零损伤表面的实现路径

　　The Implementation Path of Zero Damage Surface

　　实现零损伤清洗的核心在于对空化效应的精细化控制。设备采用双频切换技术，在剥离顽固污渍时启用40kHz低频段产生强冲击力，在精细清洗阶段自动切换至80kHz高频段，将空化气泡尺寸控制在微米级，防止对元件镀层产生侵蚀。

　　The core of achieving zero damage cleaning lies in the precise control of cavitation effects. The device adopts dual frequency switching technology, which uses a 40kHz low frequency band to generate strong impact force when peeling stubborn stains, and automatically switches to an 80kHz high frequency band during the fine cleaning stage, controlling the size of cavitation bubbles at the micrometer level to prevent corrosion of the component coating.

　　清洗篮具的工程学设计同样关键。采用仿生学支撑结构，使元件与载具的接触面积降低70%，配合弹性硅胶固定点，既确保了清洗过程中的稳定性，又避免了机械夹持造成的表面划痕。对于镀金引脚等敏感部位，设备可自动降低该区域的声强密度，形成局部保护声场。

　　The engineering design of cleaning baskets is equally crucial. By adopting a biomimetic support structure, the contact area between the component and the carrier is reduced by 70%. Coupled with elastic silicone fixing points, it ensures stability during the cleaning process and avoids surface scratches caused by mechanical clamping. For sensitive areas such as gold-plated pins, the device can automatically reduce the sound intensity density in that area, forming a local protective sound field.

　　智能清洗的微观控制

　　Micro control of intelligent cleaning

　　设备搭载的光学在线检测系统，可对0.5μm以上的微粒进行实时监测。当检测到清洗效果达标时，系统自动终止主清洗程序，转入漂洗阶段。这种闭环控制机制使清洗剂消耗降低30%，同时避免了过清洗导致的表面粗糙度上升。

　　The optical online detection system equipped on the equipment can monitor particles larger than 0.5 μ m in real time. When the cleaning effect meets the standard, the system automatically terminates the main cleaning program and enters the rinsing stage. This closed-loop control mechanism reduces the consumption of cleaning agents by 30% while avoiding the increase in surface roughness caused by over cleaning.

　　对于多材质混合元件，设备通过介质电导率检测技术，智能识别金属、陶瓷、高分子材料的分布区域，动态调整清洗液的pH值与表面张力。例如，在清洗陶瓷基板时，系统自动将清洗液pH值控制在8.5-9.5区间，防止碱性环境对陶瓷材料产生腐蚀。

　　For multi material hybrid components, the equipment uses medium conductivity detection technology to intelligently identify the distribution areas of metal, ceramic, and polymer materials, and dynamically adjust the pH value and surface tension of the cleaning solution. For example, when cleaning ceramic substrates, the system automatically controls the pH value of the cleaning solution within the range of 8.5-9.5 to prevent corrosion of ceramic materials in alkaline environments.

　　In the field of semiconductor packaging, the fully automatic ultrasonic cleaning machine can thoroughly remove the residual flux between solder ball arrays, controlling the ion contamination level at 0.1 μ g/cm² The following significantly improves the reliability of chip level packaging. For optical lens components, the device can remove fingerprint residues at the 0.1 μ m level, ensuring a transmittance loss of ≤ 0.5%.

　　设备内置的清洗效果数字孪生系统，可生成三维污染热力图，为工艺优化提供数据支撑。通过机器学习算法，系统持续完善清洗参数库，使不同批次的元件清洗一致性突破99%，为大规模精密制造提供了质量保障。
