R8A77760DBGV Reballing Stencil

This is not a single electronic component but a precision reballing stencil designed for the Renesas R8A77760DBGVintegrated circuit. The Chinese characters 绿油网 (lǜ yóu wǎng) translate to “green oil mesh” or “green oil screen,” and “Film” confirms that it is a type of stencil. This likely refers to a stencil with a special, non-stick coating or a specific mesh structure that is optimized for applying solder paste.

Product Description

This is a professional-grade reballing stencil used for re-establishing the connections on a Renesas R8A77760DBGVprocessor. This particular tool is part of a premium line, featuring a special “green oil mesh” or “film” surface that likely provides superior performance.

• Chip Compatibility: The stencil is specifically designed for the Renesas R8A77760DBGV, a high-performance microprocessor from the automotive-grade R-Car family. This chip is a critical component in the infotainment, navigation, and display systems of modern vehicles.
• Unique Features: The “绿油网” feature likely provides a more advanced method of applying solder paste. This could be due to a specific surface coating that prevents solder paste from sticking to the stencil after reflow or an etched mesh design that ensures uniform paste deposition. This is a specialized feature that separates it from standard stencils, making it ideal for delicate, high-value repairs.
• Application: The stencil is an essential tool for technicians repairing a car’s infotainment unit. The R8A77760DBGV chip, like all BGA components, can fail due to vibrations or thermal stress, leading to a black screen, system crashes, or other malfunctions. Reballing the chip with this stencil is a cost-effective alternative to replacing the entire unit.
