How to choose the appropriate configuration of the probe station and how to determine the accuracy? The following issues usually need to be identified to determine the probe station selection: 1. How many inches of wafers or devices need to be measured? Zh 2. How high is the mechanical accuracy of the probe station? Zh 3. What is the size of the spot sample? A 100um * 100um or 60um * 60um

Modern physics experiment "Research on Plasma in Gas Discharge" has experimental equipment, and a transition from theory to practice began with SSV-40 Background: The experiment "Research on Plasma in Gas Discharge" is one of the compulsory experiments in modern physics experiments in universities, but no company or individual has produced a complete set of corresponding experimental equipment,

Anatomy of a Probe Station System The probe station system is divided into a manual probe station and an automatic probe station. Below we mainly analyze the manual probe station: Probe station use: The manual probe station is also known as the probe test station. The main purpose is to provide a test platform for the electrical parameter test of semiconductor chips. The instrumen
