High Vacuum Rapid Exchange Sample Loader

Electro-Magnetic Assembly

Manufacture of High Vacuum Rapid Exchange Sample Loader For The Semiconductor Industry

Alpine Precision has earned a reputation for precision electro mechanical assembly services. As a result, our company was selected to perform the assembly of this high vacuum, rapid exchange autoloader for semiconductor defect analysis. This assembly required electronics integration, cosmetic surfacing, calibration to a mock SEM, vacuum preparation, helium leak checking, packaging for international shipment

Custom control plans were developed to ensure compliance with our customer’s specifications as well as domestic and international standards.  Manufacturing process plans were designed to ensure consistency between builds and copy exact compliance.  Critical attention was paid to ensure cosmetically pleasing appearance of finished unit.
