Where are the application fields of solder paste?

Solder paste is a type of soldering material used for surface mounting of electronic printed circuit boards,It is widely used in the maintenance operations of watch instruments, precision components, medical devices, stainless steel handicrafts, tableware, mobile communication, mobile phones, computer boards and cards, and can also be usedBGAAnd the production operations of other electronic components. Below, the solder paste manufacturer will briefly discuss the degree of understanding.

Flux pasteA general term for fluxes used in various welding processes; Solder paste specifically refers to the flux for soldering. Both of the above have strong soldering assistance effects and can be used for soldering iron parts. However, there will be residual solder paste after soldering, which may cause corrosion and leakage of electricity to the workpiece in the future. Generally, they are not suitable for printed circuits and electronic circuits.

Flux paste can be provided in various packaging methods, such as bottle type, syringe type, etc., to meet the requirements of different products and processes of customers. Solder paste is usually best stored in the refrigerator at a temperature of5-10℃It's best. Therefore, when taking the solder paste out of the cold box, its temperature is much lower than the room temperature. If the bottle cap is opened without "warming up", it is easy for the water vapor in the air to condense and adhere to the solder paste, and during the welding process (usually when the temperature exceeds200℃The moisture rapidly vaporizes due to intense heat, causing a "splashing" phenomenon, generating tin beads and even damaging components. Warming method: Without opening the bottle cap, place it at room temperature to thaw naturally and warm up4About an hour. When warming up, be careful not to open the bottle cap without sufficient warming up. Do not shorten the "warming up" time by heating.

The main functions of solder paste:

1,PCBADuring the plate brazing process, the oxides on the surface of the base metal and the liquid brazing filler metal are removed to create conditions for the spreading of the liquid brazing filler metal.

2It is covered with a thin layer of liquid on the surface of the base metal and the filler metal to isolate air and provide protection.

3It plays an interfacial active role and improves the wetting and spreading performance of the liquid filler metal on the surface of the base material.
