Most people know it nowLEDWelding is used forMedium-temperature lead-free solder pasteIn 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? Let's talk about it, solder paste manufacturers:

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 pasteLEDThe LED beads often experience dead lights, that isLEDLamp beadsPNThe knot was melted during reflow soldering, and some othersPCBThe board is not resistant to high temperatures either. SuitableLEDThe solder paste used for soldering is medium-temperature lead-free solder paste.LEDSpecial medium-temperature lead-free solder paste, which can provide high-quality printing and forming at low reflow temperature, has excellent thermal collapse resistance and can stay in harsh environments4It can still print smoothly even in hours, and the speed can also be achieved when printing fine and small products100millimeter/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.
