Wafer level camera shooting module WLC automatic testing socket

Abstract

The invention discloses a wafer level camera shooting module WLC automatic testing socket which comprises a base, a module placing structure and a light source unit. The base is connected with a PCB pinboard. The base comprises a test unit which is mounted in a socket maintaining frame. The test unit comprises a plurality of test probes, a probe maintaining main body and a probe maintaining plate, wherein the probe maintaining main body and the probe maintaining plate are sequentially distributed in the direction far away from the PCB pinboard. The module placing structure comprises a placing maintaining frame and a floating plate, the placing maintaining frame is provided with at least one module placing groove, and the floating plate is arranged between the module placing groove and the probe maintaining main body. The light source unit comprises an LED lamp panel and a standard plate which are arranged inside a camera obscura. The module placing groove, a lens connected to the placing maintaining frame, the LED lamp panel and the standard plate are sequentially distributed in the direction far away from the PCB pinboard. The wafer level camera shooting module WLC automatic testing socket can be compatible with different testing machines, automatic, efficient and accurate testing of a WLC module can be achieved, and the module and a chip can not be damaged.

Description

technical field [0001] The invention relates to a chip testing device, in particular to a wafer-level camera module WLC automatic testing socket. Background technique [0002] Wafer-level camera module WLC series is a new type of CMOS chip imaging integrated system developed by American APTINAIMAGING and Kunshan Xitai QTECH. Wafer Level Optical Lens WLO (Wafer Level Optical) WLO is assembled to form a camera pair module. [0003] At present, most of the CMOS imaging modules are loaded with flexible circuit boards for SMT assembly, and the structure is relatively complicated. Due to the large number of components, the functions realized are not as direct and reliable as WLC imaging modules. Correspondingly, the existing module test socket is suitable for the structure of the existing camera module. For functional testing, ICT probes are generally used for detection. The structure is complex and prone to open and short circuits; the stability is poor. The service life is gre...
