JJY | What are the features and advantages of low-temperature solder paste?

AccompaniedSMTThe development of technology andLEDThe progress of the industry, yesLow-temperature solder pasteThe demand is increasing day by day. Previously, JJY solder Paste Manufacturer analyzed the differences between high and low temperature solder pastes and their respective application scopes for everyone. Here, we will give you a simple popular science introduction. The main difference between high and low temperature solder paste lies in this "temperature". Some chips orPCBSurface mount components cannot withstand it200℃When the temperature is above and the surface mount reflow process is required, low-temperature solder paste should be used for soldering, which can play a protective role. Therefore, low-temperature solder paste is very sensitiveLEDThe industry welcomes it. Its composition is mostly tin-bismuth alloy, and the peak temperature of reflow soldering is usually170℃-200℃The melting point is138℃Left and right, mainly used for welding radiator modulesLEDWelding, high-frequency welding, etc.

In order to seizeLEDWith such a vast market, major manufacturers have always attached great importance to the research and development and production of low-temperature solder paste. At present, most low-temperature solder pastes haveSAC305For reference, conduct a quality comparisonindium5.7LT-1As a representative, its low-temperature anti-drop impact solution is indeed very good. After all, it is a well-known brand, but the issue of brand premium in terms of price is inevitable. In fact, to achieve the same effect, there could be better options available, and in some aspects such as price, they might even be more outstanding. The previous JJY solder paste manufacturer is replacing imported products with domestic onesSMTAs mentioned in the article "Solder Paste", inSMTIn the field of solder paste, we basically have the strength to replace imported brand products. Naturally, asSMTFor some types of solder paste, the low-temperature solder paste series products of JJY Technology will also be your better and more cost-effective choice.

Low-temperature lead-free solder paste is developed by JJY Technology and is suitable forSMTA no-clean solder paste of the process, using lead-free alloy solder powder of the tin-bismuth series with low melting pointsSn42Bi58T4It is made by mixing fine powder and low-temperature type flux paste, suitable for welding processes or secondary reflow processes that require low temperatures, and can effectively protect those that cannot withstand high temperaturesPCBAnd electronic components. Now let's explain to you what features and advantages they have:

1Environmentally friendly solder paste with very little residue, no need to clean after soldering.

2The filling solder paste printing has good rolling and tin dropping properties, and is low to0.3mmThe pitch pads can also achieve exquisite printing. The dispensing of solder paste with a syringe is smooth and the viscosity is stable.

3When printing continuously, its viscosity changes extremely little, and the operational service life of the steel screen is long, exceeding8It will not dry out even after hours and still maintain a good printing effect.

4It can meet the requirements of welding equipment of different grades, does not need to be completed in a nitrogen-filled environment, and still shows good welding performance within a wide range of reflow oven temperatures.

Advantages of JJY low-temperature solder paste

A lower melting point offers more advantages in preventing substrate deformation and reducing energy consumption costs.

Both the tensile strength and elongation have been significantly enhanced, endowing the weld points with higher strength and fatigue impact resistance.

It has a greater balanced wetting force and a shorter wetting time, demonstrating more excellent alloy wetting performance.

Combined with the unique solder paste formula of JJY Solder paste manufacturer, it can increase the straight-through rate of the customer's production line and effectively reduce production costs.
