Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0022] see figure 1 As shown, in this embodiment, a production process of a rectangular electrical connector includes the following steps:

[0023] a. Material selection: use a soft-hard combination board as the printed circuit board 1, and use a brass pin 3 with a gold-plated layer on the surface;

[0024] b. Solder type selection: use the thermal analysis simulation method to simulate and test the conduction temperature range at the soldering end of the pin 3 after the non-welding end is heated, and select the solder according to this range. The melting point temperature of the solder is greater than the conduction temperature range, and the solder te...

Abstract

The invention discloses a production process of a rectangular electrical connector. The production process comprises the following steps of (a) material selection; (b) welding flux model selection; (c) welding; (d) embedment; and (e) curing. According to the production process of the rectangular electrical connector, a rigid-flex board is selected as a printed circuit board and has excellent bending-resistant performance, and the vibration-resistant performance is greatly improved; moreover, a pin made of a brass material is selected, the signal transmission performance is improved, relativelygood heat transmission characteristic is achieved, and the cooling effect can be effectively improved; a gold-plating layer arranged on a surface of the pin has relatively good corrosion-resistant characteristic, and a good protection effect is achieved; the temperature of a welding end of the pin is simulated and tested by a thermal analysis method after a non-welding end of the pin is heated, welding flux is further reasonably selected, the pin is enabled to have relatively high heat resistant performance during the post application process, pin falling or disconnection is difficult to occur.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a production process of a rectangular electrical connector. Background technique [0002] Rectangular electrical connector is a kind of electrical connector widely used in domestic high-end electronic systems. It is different from conventional circular electrical connectors. Rectangular electrical connectors do not have a metal shell to fix the pins. The rectangular potting glue is used to fix the pins; because the potting glue is used to fix the pins, its anti-vibration performance is poor, and the rectangular electrical connectors on the existing market have poor heat resistance. In the process of secondary enamel tinning, pins are prone to fall off, so it needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to provide a production process of a rectangular electrical connector to solve the problems of poor temperature re...
