Solder pasteIt is one of the common raw materials for soldering electronic devices. Solder paste is also called solder paste, and its English name issolder pasteGray or grayish black paste. Solder paste is accompaniedSMTA new type of welding material that has emerged as The Times require is a paste-like mixture formed by mixing solder powder, flux, and other surfactants, thixotropic agents, etc. Mainly usedSMTIndustryPCBSurface resistance, capacitanceICSoldering of electronic components, etc. From the surface, the gray paste is lead-free and environmentally friendly solder paste, while the grayish-black one belongs to lead-containing solder paste. Today, JJY Factory will introduce to you in detail how to set the price of solder paste?

The price of solder paste is influenced by multiple factors. One is the price fluctuations of raw materials such as tin powder, flux, and active agent. The other is labor costs, packaging material costs, etc. For the latest and most recent solder paste prices, please consult online or call Double Chile. 

How to determine the price of solder paste: 

Solder paste is composed of tin alloy and is divided into two types: heavy metal-free solder paste and heavy metal solder paste. Its price lies in the proportion of solder paste alloy raw materials. For example(sn63Representing the proportion of tin componentspb37Representing the proportion of lead content, that is1kgThere are welding wires0.63kgTin and0.37kgLead constitutes the price of solder paste! 

The higher the price of solder paste is, the better the quality of solder joints will be? 

It is well known that the function of solder paste is to firmly attach electronic components to the circuit board. The firmness of the solder joints determines the actual effect of soldering and disassembly. At the present stage63/37Solder paste has a relatively high proportion among all alloys, and its melting point and freezing point are183Degree, and tin-silver-Copper alloy218Degree of(After welding these two alloys with electrodes of different proportions, the welding points were compared using the flow diversion method and a spectrometer, and it was found that63/37It occupies a prominent position in affirming data information. 

The higher the solder paste is, the higher it gets? 

The amount of solder paste used throughout the welding process is very large, accounting for a certain proportion of the cost factors in the entire welding process. Solder paste contains different alloys and has different compositions and prices. Among all the proportions, the solder paste of tin-silver-copper alloy is relatively expensive. Its application scope is products with high requirements for the anti-interference performance of electronic devices, such as(Electronic device navigation bar, notebook motherboard, high-end audio equipment).Ag-Ag-CuAlloy electrodes have very good advantages in this category, but they are stronger than solder paste in terms of lubricity, development protection, color and solder joints.
