Abstract

A modular pressing device capable of generating stage downward forces is provided. The modular pressing device comprises a non-exchangeable pressing module and an exchangeable pressing module. The non-exchangeable pressing module includes a first downward force generating unit. The exchangeable pressing module includes a second downward force generating unit. The first downward force generating unit applies a first downward force to at least one of a testing seat and an electronic device through the exchangeable pressing module. The second downward force generating unit applies a second downward force to the electronic device. Thereby, the modular pressing device is capable to generate two different downward forces to reduce the downward surge force. In addition, as the exchangeable pressing module is worn, the exchangeable pressing module can be replaced quickly such that the maintenance cost can be effectively reduced and the stability of the apparatus can be enhanced.
