Advanced ceramics are increasingly used in industries that require materials with exceptional properties — such as high-temperature resistance, corrosion resistance, hardness, and even special sensing properties (like pressure or light sensitivity). These materials play a key role in semiconductor packaging and precision components.
🎯 Use Case: Surface Inspection of Ceramic Blades
A great example of ceramic application is the ceramic bonding blade, widely used in the IC (integrated circuit) packaging industry. This blade is a key consumable tool installed on bonding machines to connect gold or copper wires between chips and circuit boards.
Ceramic blades are often called the “hidden gem” of precision ceramics due to their crucial role and low cost. With copper wire increasingly replacing gold wire as the standard bonding material, the quality of ceramic blades — especially their surface roughness and geometry — becomes even more important.
To ensure precision during bonding, the inner hole diameter of the ceramic blade must be about 1.4 times the diameter of the bonding wire. Since modern microelectronic wires can be as small as 1 to 3 micrometers, the inspection equipment used must be extremely accurate.
🔍 Why Use Chromatic Confocal Sensors?
Hypersen’s chromatic confocal displacement sensor is ideal for this type of inspection. Here’s why:
