Description

Technical Field

[0001] The utility model belongs to the field of protective cover jigs, and specifically relates to a novel pressure measurement protective cover jig for an ACF process hot press. Background Art

[0002] A new ACF process hot press pressure measurement protective cover fixture is a widely used technical product in the camera module industry. It mainly heats the hot press head and presses the anisotropic conductive glue between the FPC and PCB to achieve electrical conduction between the FPC and the PCB conductive pad to achieve electrical function of the camera module. The key parameter of this process is pressure: an instrument is required to measure pressure. The pressure measurement method affects the crushing effect of conductive particles. For this purpose, a pressure sensing head protective cover fixture is specially designed to assist the instrument in measuring pressure, improving the accuracy and stability of measurement data.

[0003] Currently, the ACF process is the most widely used in the camera module industry. The pressure measurement method is that the pressure gauge sensor head directly measures the pressure within the stroke of the thermal press head. The pressing surface and the measuring surface are estimated manually. The pressing height of different products is inconsistent. The equipment technicians set the machine stroke parameters each time, which is cumbersome and inaccurate.

[0004] In view of this, the present utility model is proposed. Utility Model Content
