【 Solder Paste Manufacturer 】 Will the quality of solder paste specifically for leds be affected?

Nowadays, withLEDWith the rise of lamps, incandescent lamps, fluorescent lamps and other light bulbs have gradually withdrawn from the market, and more and more people have begun to engage in this fieldLEDIndustry. In recent yearsLEDThe rapid development of the industry has also driven the soldering industry. With the change in demand, major soldering factories have developedLEDSpecial solder paste, thenledWill the quality of the lamp be affectedLEDWill the quality of the dedicated solder paste have an impact? Today, let's discuss it together with the solder paste manufacturers.

Will have an impactledThere are many reasons for the expiration date of the lamp, such as the application field scenario, environmental humidity, power supply current, production process, welding technology requirements, etc. At the same time, it will also have an impactledThe service life of the lamp has been affected. Let's all talk about it one by oneLEDWhat are the influences of special solder paste in various factors?

1Application field scenarios:

There are some outdoorsLEDThe screen needs to be exposed to the sun or rain indoors for a period of time, so there are requirementsLEDThe solder joints of the display screen mainboard have a certain degree of toughness; otherwise, it would be due to unstable solderingledThe light sheet has fallen off, so we need to choose a good quality oneLEDSpecial solder paste is needed so as to ensure that the toughness of the solder joints is strong enough.

2Environmental humidity:

Compared with other incandescent lamps and fluorescent lamps, evenLEDThe lamp is more energy-efficient, but it won't100%Convert electrical energy into light energy.LEDConversion efficiency is20~30%The rest of the electrical energy is converted into thermal energy.LEDThe reason why the lamp still gets hot during use is that the overheated surface temperature can cause thermal shock to the solder joints. Therefore, the thermal stability of the solder paste is also the most important.

3Supply current:

ledLight strips are generally powered by constant voltage power supplies (DC switching power supplies), and it is necessary to maintain the effectiveness of a stable voltage. At this time, the conductivity of the solder joints needs to be excellent; otherwise, it will cause unstable voltage. YesledLights bring impact.

4Production process:

LEDDuring the production process of the screen, the through-furnace soldering technology requirements can usually be adopted, and the entire process is carried out by mechanical equipment. Considering that mechanical equipment is different from manual soldering and has the ability to distinguish, if the quality of the solder paste is too poor, it is more likely to cause false soldering or false soldering. ThereforeLEDSpecialized solder paste has extremely high requirements for flux, so as to ensure that false soldering and false soldering are less likely to occur.

5Welding technical requirements:

All other factors can be seen to be closely related to the quality of the solder paste product, which is of high qualityLEDSpecial solder paste has higher soldering strength and better performance.

All in all,LEDSpecial solder pasteThe quality of the product is targeted atledThe quality of lamps has a certain influence, which is why they are chosenLEDWhen choosing a dedicated solder paste, it is essential to select one with superior product quality based on your own market demands.
