Problems solved by technology

The existing automated process production line still cannot fully meet the production needs, and its defect mainly lies in the low yield rate of the final product
[0004] The main problem that causes the low yield rate is that the automation process is easy to cause damage to the leads, thus weakening the stability of the network transformer

Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0033] Such as figure 1 As shown, a dual in-line packaging process is characterized in that it comprises the following steps:

[0034] Preliminary tinning, connect the wires of the network transformer 1 to the pins for preliminary tinning;

[0035] Preliminary baking, baking the network transformer 1 after preliminary tinning to prepare for the upper cover;

[0036] The upper cover is baked, and the network transformer 1 after the upper cover is baked to obtain a semi-finished product;

[0037] Secondary tinning, the semi-finished products after finishing and assembling the pins are subjected to secondary tinning of the assembling pins;

[0038] Finished product inspection, conduct high-voltage test and comprehensive test on semi-finished products ...

Abstract

The invention belongs to the technical field of network transformer manufacturing, and discloses a double in-line package process. The method comprises the following steps: performing primary tinning; performing preliminary baking; baking the upper cover; performing secondary tinning; detecting a finished product, wherein in the steps of preliminary baking and upper cover baking, preliminary baking and upper cover baking are completed through a circulating baking oven, the baking temperature is 115-125 DEG C, and the baking time is 18-22 min. According to the invention, the network transformer is circularly baked at a proper temperature for a proper time, so the use stability of the network transformer is improved, and the requirement on the yield is met on the basis.

Description

technical field [0001] The invention belongs to the technical field of network transformer manufacturing, and in particular relates to a dual in-line packaging process. Background technique [0002] The current dual-in-line packaging process is generally completed manually, and the operations at each stage are complicated and time-consuming. A complete production process takes nearly 3 working days, resulting in low production efficiency. [0003] In view of this, designing a set of mature automatic process production line is an urgent problem to be solved. The existing automated process production line still cannot fully meet the production needs, and its defect mainly lies in the low yield rate of the final product. [0004] The main problem causing the low yield rate is that the automation process is easy to cause damage to the lead wires, thereby weakening the stability of the network transformer. Contents of the invention [0005] In order to solve the above-mention...
