Oil Leak issue on ASI2600MC Pro and other cameras

Some users have reported an “oil leaking” issue on the ASI2600MC Pro and in some instances on other camera models back in 2021. After research and investigation, we found the issue was caused by the thermal pad, which is a thermal conductive material sits between the sensor and backplate for optimal heat dissipation of the cameras. After long-term exposure to high temperatures, the volatile content of vinyl silicone oil in the pad would migrate to its surface, and then infiltrate through the gap between the sensor and the board, and in some cases bleed to the sensor surface. After discovering this oil leaking problem, we have improved our production process by switching to thermal pads with a lower volatile content to reduce volatilities. Cameras manufactured after October 2021 should not suffer from the oil leaking problem.
