The WIT-1 fully automatic intelligent sample preparation system is specifically developed for cross-sectional slice detection in industries such as semiconductors and PCB… It can be used for precise positioning detection and analysis of PCB holes, copper,solder joints, and tin balls. It uses a high-definition CCD camera to determine the grinding position, enabling it to automatically complete processes such as rough grinding, fine grinding, fine polishing, and cleaning.
Features：
1）High-precision CCD lens for sample calibration offers high accuracy and a large field of view, achieving a grinding precision of ±10μm.
2）Multiple grinding lines can be calibrated on a single sample at once. After completing one grind, it automatically proceeds to the next without requiring recalibration.
3）Automatically adjusts the grinding angle to correct samples that are tilted during mounting.
4）Can hold up to 3 samples simultaneously for grinding and polishing.
5）The pressure and speed applied to the sample are controllable, preventing cracking or breaking due to excessive pressure.
6）Equipped with laser marking/coding for sample traceability.
7）Dual workstations with automatic grinding disc changeover; can accommodate up to 20 grinding discs.
8）Capable of photographing the ground/polished surface.
9）Configured with 4 sets of different polishing fluids, 2 of which have mechanical stirring; all 4 sets feature liquid level alarms.
10）Includes a cleaning station with ultrasonic cleaning, water rinsing, and air blow-drying.
11）Processed samples are placed face-up and arranged orderly in the recovery tray to avoid scratching the prepared surface.
