OurLEDSpecial solder paste"Melting point"183℃Lead-free medium-temperature solder paste is in accordance with the European UnionRoHS2.0The latest directive is to use spherical environmentally friendly solder alloy powder with low oxidation rate and environmentally friendly flux with extremely strong thermal stability and good thixotropy, and is refined through advanced solder paste vacuum mixer technology. Applicable toLEDAssemblySMTFor various high-precision soldering that requires medium and low-temperature reflux in industrial production, the following is an explanation from JJY solder Paste Manufacturer:

LEDStorage and use of special solder paste:

Refrigerated storage will extend the lifespan of solder paste. Low-temperature solder paste is less than10℃When stored under certain conditions, the storage life is6One month. The solder paste should be thawed to room temperature before use. The thawing time is2~3Hours.

LEDSpecialized solder paste printing suggestions:

Angle:60Degree is the standard.

Coating hardness: When the coating spacing is less than0.1mmWhen using, the Angle of the scraper should be45Degree80~100Rubber scrapers with Shore hardness have the best effect. The best effect is achieved if a stainless steel scraper is used.

The printing pressure is set based on the length and speed of the squeegee to ensure that no solder paste remains after the squeegee passes through the steel plate. Usually, this pressure is set at200g/About one square centimeter.

LEDThe printing speed of special solder paste: It depends on the structure of the circuit board, the thickness of the steel plate and the printing capacity of the printing machine.

Template material: Stainless steel, brass or nickel-plated plate. The design of steel mesh formwork is very important. It is recommended that the printing performance of laser cutting and electrocasting steel mesh is the best.
