Embodiment Construction

[0034] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0035] In order to increase the stability of the chip in the circuit board, the bottom of the chip is usually provided with a filler layer to protect the solder balls and solder joints of the chip in the circuit board after soldering. Both the dismantling and welding of the circuit board need to be heated, and the filler layer at the bottom of the chip is heated and expands, which can easily lea...

Abstract

The invention relates to a circuit board maintenance jig which comprises a jig body used for installing a circuit board, the jig body is connected with an airflow driving mechanism, and the airflow driving mechanism drives airflow in the jig body to flow; the maintenance jig for the circuit board further comprises an airflow channel formed in the jig body and vent holes formed in the jig body, the vent holes are communicated with the airflow channel, and the jig body is communicated with the airflow driving mechanism through the airflow channel. In a mounting state, the vent holes correspond to the circuit board. The vent holes are communicated with the airflow channel, the jig body is communicated with the airflow driving mechanism through the airflow channel, when the airflow driving mechanism drives airflow in the airflow channel to pass through the vent holes, heat on the surface of the circuit board is taken away, and thus the surface temperature of the circuit board is effectively reduced.

Description

technical field [0001] The present disclosure relates to the technical field of electronic component maintenance, in particular to a jig for circuit board maintenance. Background technique [0002] With the development of science and technology, the circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. In order to protect the circuit board, it is usually installed in an electrical appliance in a packaged form. [0003] The package form refers to the shell used to install the semiconductor integrated circuit chip, which plays the role of installing, fixing, sealing and protecting the chip. Integrated circuits need to be heated during assembly and maintenance. If the temperature is too high, it will cause chip tin cracks, and then damage the electronic components in the integrated circuit. Contents of the invention [0004] In order to ...
