What are the performance differences between LED solder paste and ordinary solder paste?

LEDFor special useSolder pasteAs the name suggests, it is specifically used inLEDSolder paste in the industry. People in the electronics industry should all be aware that solder paste is an indispensable soldering material in the production process of electronic devices. Most of the component patches are soldered out with solder paste. SoLEDWhat are the differences in performance between solder paste and ordinary solder paste? The following is JJYSolder paste manufacturerLet's share it together:

LEDThe difference between solder paste and ordinary solder paste

1Tin powder particlesLEDThe printing of chips is usually of high density and narrow spacing. The opening size of the template is relatively small, and small-particle alloy powder must be used; otherwise, it will affect the printability and demolding property.

2Thermal conductivity: Due toLEDThe chips are relatively small and are usually densely printed on a large scale or use high powerLEDWhen the chip is being packaged, heat dissipation becomes a major problem at this point. IfLEDThe generated thermal energy cannot be conducted to the substrate in real time, which will cause light attenuation. ThereforeLEDThere is a high requirement for heat dissipation performance.

3Electrical conductivity: AverageLEDAll the light strips are powered by constant voltage power supplies (DC switching power supplies), and it is necessary to maintain the stability of the voltage. Therefore, the conductivity of the solder joints needs to be extremely excellent; otherwise, it is easy to cause unstable voltage. YesLEDThe lamp generates an impact.

LEDThere are also some other differences in solder paste, which are determined by various application scenarios, such as thixotropy and solder paste viscosity. And the above-mentioned requirements areLEDNecessary. BasicallyLEDThe biggest difference between solder paste and ordinary solder paste. Of course, ordinary solder paste does have these characteristics, butLEDThese several properties of solder paste are more prominent and its performance is relatively higher.
