Embodiment 1

[0020] The present invention mainly aims at the chip loading process in the chip packaging process, and provides a surface aging detection process for power devices, including the following steps:

[0021] In order to achieve the above object, the present invention provides a surface aging detection process for power devices, the steps are as follows:

[0022] Step 1. Take the finished product from the upper station from the conveyor belt, check whether there is any defect in appearance, and then put it on the aging fixture of the aging room;

[0023] Step 2. Fix the AC input terminal and DC output terminal of the monomer;

[0024] Step 3, repeat the above actions, fill the burner rack, and plug in all the sockets;

[0025] Step 4. Turn on the host computer, select the burn-in program corresponding to the model to start the burn-in;

[0026] Step 5. The inspector checks the status of the indicator light every 30 minutes and records it in the daily inspection report. If the l...

Abstract

The invention relates to a surface aging detection process of a power supply device, comprising the following steps: taking the finished product from the conveyor belt, checking that there is no bad appearance, and putting it on the aging fixture of the aging room; fixing the AC input terminal and DC output of the monomer terminal; repeat the above actions, fill the burner rack, and plug in all the sockets; turn on the host computer, select the aging program corresponding to the model to start the burner; the inspector checks the status of the indicator light every 30 minutes and records it at the point Check the daily report, if the light flashes or the light does not light up, it is defective; the defective product is attached with a defective label and placed in a defective plastic frame to be repaired. And recorded in the daily report; when the aging is completed, remove the monomer and check whether there are explosion-proof ports The protrusion is broken; the products with aging OK are confirmed to be qualified and placed on the lower layer of the conveyor belt. The surface aging detection process of the power supply device of the present invention has the advantages of simple operation process, strong operability, good detection effect, accurate positioning during detection, and high detection detection rate.

Description

technical field [0001] The invention relates to the electronics industry, in particular to a surface aging detection process for power supply devices. Background technique [0002] With the development of science and technology, the electronic industry has advanced by leaps and bounds, the demand for various integrated and control circuits has increased rapidly, and the demand for chip packaging has also increased rapidly. A power supply is a device that converts other forms of energy into electrical energy. The power supply is based on the principle of "magnetism generates electricity", which is generated by renewable energy sources such as hydraulic power, wind power, sea tide, dam water pressure difference, solar energy, and burning coal and oil residue. Generators can convert mechanical energy into electrical energy, and dry batteries can convert chemical energy into electrical energy. Generators and batteries themselves are not charged. Its two poles have positive and...
