What is the cause of false welding in 华体会体育·（中国）股份有限公司官网A processing?
In 华体会体育·（中国）股份有限公司官网A treatment, faulty soldering sometimes occurs Virtual welding is also known as cold welding, whICh means that parts seem to be welded on the surface, but they actually have no internal connection or are in an unstable state in the middle, and they are not always connected together It will not only affect the characteristics of the circuit, but also lead to the disqualification or even scrapping of the 华体会体育·（中国）股份有限公司官网 The following describes the cause and solution of the failure 华体会体育·（中国）股份有限公司官网 component processing virtual welding
华体会体育·（中国）股份有限公司官网A

1) 华体会体育·（中国）股份有限公司官网A virtual soldering is a common line fault, and the common causes of virtual soldering are the following two:
1. In the production process, it is caused by improper production process, such as poor welding or lack of tin, non-conductive element pins and pads, etc, and the circuit board is in an unstable state where it is always connected and not connected;
2) Due to the long term use of electrical appliances, some parts with severe heat are easy to age and peel off, or impurities appear in the solder joint at the weld leg
Second, the method to solve the 华体会体育·（中国）股份有限公司官网A virtual solving:
1) The components must be stored in a moisture-proof storage, such as a moisture-proof cabinet;
2) The in-line electrical appliances can be slightly polished before welding;
3) When soldering, you can use solder paste and flux, and it is better to use reflow soldering machine, manual soldering requires good skills;
4) Reasonably choose a good 华体会体育·（中国）股份有限公司官网 substitute material
In the process of 华体会体育·（中国）股份有限公司官网A processing, virtual soldering is an important reason that affects the quality of 华体会体育·（中国）股份有限公司官网 in case of faulty soldering, rework is required, which not only increases labor pressure, but also reduces production efficiency and causes losses to the enterprise Therefore, it is necessary to avoid virtual welding as much as possible The occurrence of the phenomenon should be carefully checked. Once false welding occurs, the cause should be found and solved immediately
