We can propose a socket structure that does not require LID for measurements such as image sensors that need optical testing.
In measurements such as those involving image sensors, it is essential to incorporate light; however, in a typical socket structure, the presence of a pressurized LID can create a situation where light has difficulty entering. To address this issue, PCR has developed a LID LESS socket that distorts the contactor by attracting the package from the backside in a vacuum, allowing for conduction. The absence of a pressurized LID enables free light intake, eliminating constraints in socket design. Additionally, the lack of a LID simplifies and reduces the cost of the socket, making it feasible for cost reduction efforts beyond just image sensor measurement applications. However, since the pressure is determined by atmospheric pressure, there may be cases that cannot be accommodated depending on the size and pin count of the semiconductor package. For detailed specifications, we will conduct individual designs for each project, so please feel free to contact our company for inquiries.

Detailed information
-
PCR enables a test socket structure that does not require pressurizing the top of the package by using a special specification. (It does not require a pressurizing lid for the socket.) As a result, it becomes easy to measure products that cannot have the top of the package pressurized, such as image sensors.
