I. Why does N11 Piezo Motor Stand out

In the refined manufacturing process of LED light-emitting chips, repairing individual damaged chips is the key to improving the yield rate. The high-precision displacement capability of the N11 piezo motor has become the core support for the LED chip repair link.

◆ 1. Construction of dynamic through holes: Place and combine four N11 1-axis piezo motors  in pairs, and install specially made templates with rectangular notches on them. By controlling the coordinated movement of four N11 piezo motor, a through hole (light-transmitting slit) with adjustable size and position can be formed at the center.

◆ 2. Precise defect location: When a defect in a certain LED chip is identified, the system can drive the N11 piezo motor to move the shielding plate, quickly and accurately exposing the target chip, providing a pure working window for laser repair. Thus, during the laser stripping of defective chips and electrode welding, damage to the surrounding normal chips is effectively avoided, achieving minimally invasive repair in the micron-level area.

◆ 3. Adaptive size: The size of the through holes can be freely adjusted from tens of micrometers to several millimeters. This means that it can easily handle LED chip products of different sizes, greatly enhancing the universality and convenience of the equipment.

This LED chip repair solution based on the N11 piezo motor is a crucial step towards fully automatic and high-yield mass production of LED chips. It can be integrated into online detection and repair equipment to achieve rapid screening and precise handling of chip defects, significantly reducing costs and enhancing core competitiveness.

In addition, CoreMorrow N59 ultrasonic piezo motor is also suitable for this system. N59 is compact in size and structure, and is less affected by external electromagnetic interference and noise. It features fast movement speed, small steps, uniform and stable performance, and high cost performance. 

In fields such as semiconductor testing and biological microscopic manipulation, probe stations are powerful tools for extending human hands and eyes and interacting with the microscopic world. The N11 series piezo motor is precisely the ideal motion module for building such high-end equipment.

◆ 1. Building  multi-dimensional motion:An XYZ 3-axis motion system can be freely built by using N11 piezo motors. Due to its extremely compact nature, the overall size of the probe station it forms can also be optimized, saving a significant amount of space for the microscope workbench or experimental chamber.

◆ 2. Precisely driving the probe: By installing the microprobe or microinjection needle on the N11 piezo motors, the control capability with nanomet-level precision can be obtained. Whether it is to locate a specific transistor for electrical performance testing or to inject drugs into a single cell, the N11 piezo motor displacement stage can smoothly and precisely deliver the probe to the target position.

◆ 3. Covering long-stroke operation: A 3.6mm stroke is of great significance in micro-operation-related applications. It means that the probe can search for the target within a relatively large range without the need for frequent repositioning of the sample, thereby simplifying the operation process and improving the efficiency of experiments and detects.

From cell microinjection in the laboratory to chip failure analysis in semiconductor factories, and even to the cutting-edge scanning probe microscopy (SPM), the probe station constructed with the N11 piezo motor can provide reliable motion support. Its modular feature allows for rapid development and customization, flexibly meeting various special scientific research and industrial needs.
