CFC pallet for photovoltaic
Semixlab's CFC tray is an ultra-light, high-strength carbon fiber composite tray designed for high-temperature processes in photovoltaic manufacturing. It has excellent thermal stability, chemical resistance and dimensional accuracy to ensure reliable handling of wafers during sintering, PECVD and automatic transfer. It is ideal for high-speed, high-precision production lines that require long-term durability and high performance. Welcome to inquire.
Description
CFC pallet (Carbon Fiber Composite Pallet) is a structural component composed of high modulus carbon fiber and high temperature resistant resin (such as epoxy resin), which is usually manufactured through precision processes such as molding and vacuum infusion.
In the photovoltaic manufacturing industry, CFC pallets are widely used in high temperature processes such as cell sintering and PECVD. As a bearing and transmission component for silicon wafers, they have excellent structural and thermal properties.
