Nowadays in the electronics industry, it is inevitable that we will encounter the phenomenon of false soldering during the soldering process. But what is false soldering? Let me explain. Generally speaking, false soldering means that only a small amount of solder adheres at the solder joint, and occasionally there is an open circuit phenomenon, that is, the contact between the component and the solder pad is poor, which greatly reduces the reliability of the printed circuit board. Therefore, How should we deal with it in order to prevent and reduce the occurrence of this phenomenonSolder wireFalse soldering that occurs when soldering components? Now, let's talk about it from JJY solder Paste Manufacturer:

There are two reasons for false soldering:

One type is during the production process, which is caused by improper production techniques, resulting in an unstable state of intermittent connection and disconnection. Another type is caused by the fact that after long-term use of electrical appliances, the solder joints of some parts that generate a lot of heat are extremely prone to aging and peeling.

Methods to solve the problem of false soldering

1Determine the approximate range of the fault based on the fault phenomenon that occurs.

2When observing the appearance, the focus should be on larger components and those with high heat generation.

3Observe with a magnifying glass.

4Operate the circuit board.

5Shake the suspicious component by hand and observe whether the solder joints of its pins are loose at the same time.

The problems of false welding and fake welding in welding ultimately stem from the employees' sense of responsibility and operational skills. It is necessary to truly cultivate a product quality awareness among employees, enhance their sense of responsibility and strengthen their operational skills. Production should be improved from all aspects such as components, tools and relevant systems to minimize and prevent the occurrence of substandard issues like false welding and fake welding to the greatest extent possible.

JJYSolder paste manufacturerThe solder wires, solder rods and solder pastes produced are all made from high-quality raw materials such as original tin ingots and original tin powder. The quality of solder products is also a decisive factor in determining the quality of their soldering. Welcome, partners who come for consultation. Let's learn and grow together!
