Which solder paste is suitable for LED soldering?

People in the industry should knowLEDSolder paste, a type of soldering material, is indispensable in the industry. SoLEDWhich kind of solder paste should be used exactly? In the early daysLEDLeaded solder paste is used in the process. Later, due to the improvement of the process, lead-free solder paste was launched on the market. Under such circumstances, lead-free solder paste was adopted due to environmental protection requirements and high temperatures. But there are three kinds of lead-free solder paste:What kind of lead-free solder paste is suitable for high-temperature, medium-temperature and low-temperature solder pasteLEDWhat about welding? Now, Shenzhen JJY Solder Paste Manufacturer will explain it:

Everyone knows that the functional characteristics vary at different temperatures. The biggest problem with using low-temperature lead-free solder paste for soldering is that the solder joints are relatively brittle and prone to dropping, and they are also prone to oxidation over time. Solder with high-temperature lead-free solder pasteLEDWhen it comes to the LED beads, there is often a dead light situation, that isLEDLamp beadsPNThe knot was melted during reflow soldering, and some othersPCBThe board is not resistant to high temperatures either. SuitableLEDWelding uses Lead-free medium-temperature solder pasteOk.LEDSpecialized medium-temperature lead-free solder paste can provide high-quality printing and molding at low reflow temperatures and has excellent resistance to thermal collapse, even when staying in harsh environments4It can still print smoothly even after hours. In addition, the speed of printing fine and small products can also be achieved100millimeter/SThe pass rate of online testing is high, meeting the reliable standard requirements of various products.

LEDProduct features of special medium-temperature lead-free solder paste:

1The solder joints have good gloss, high fatigue resistance, excellent electrical performance, and no solder beads or continuous soldering after soldering.

2It has excellent printing performance and is suitable for both manual and machine printing.

3The continuous printing performance is stable, with minimal viscosity change, and the operating life on the steel screen can reach12Maintain good printing performance for more than hours.

4Be able to adapt0.25mmThe printing requirements for spacing, good wetting performance, and effective solutions to adverse phenomena such as cold weld points.
