Shenzhen JJY Technology is a solder paste manufacturer. We have medium and high-end solder pastes (zero halogen,FPC,QFN,LEDHigh-lead, photovoltaic, high-frequency head, needle tube and other systems, wave soldering special tin bars, automatic soldering machine special tin wires, power capacitor zinc surface special tin wires, power lithium battery pack welding aluminum special tin wiresLEDSpecial no-wash tin wires for lamp boards and bulb lamp heads, etc. Today, let's have the solder paste manufacturer's editor introduce in detail the advantages and disadvantages of low-temperature solder paste. We can learn about it through some customers and partners, and also choose what kind of solder paste is more suitable for us according to our own usage situation.

Low-temperature solder paste

Advantages of low-temperature solder paste:

Low-temperature solder paste is suitable for low-temperature soldering processes and is less likely to damage or scald electronic components. Low-temperature solder paste has strong printing ability and is easy to solder solder beads, making it suitable for useSMTLow-temperature solder paste can be printed continuously24In hours, increase the production volume of your company's products.

When the surface mount components cannot withstand it200℃When the temperature is above and the surface mount reflow process is required, low-temperature solder paste should be used for the soldering process. It serves to protect the components that cannot withstand high-temperature reflow solderingPCBVery much.LEDIndustry welcome, highly suitable for high-power productionLED,LEDPackaging, etc.

JJY low-temperature solder paste adopts a special flux formula, which solves the problem of containingBiThe tin-like powder has the property of being prone to oxidation, which makes it highly solderable. It can form good wetting on the nickel-plated aluminum welding surface, has a long continuous printing life, and leaves little residue after soldering,High reliability.

Disadvantages of low-temperature solder paste:

1Its solderability is inferior to that of high-temperature solder paste, and the gloss of the solder joints is dull.

2The solder joints are very fragile and are not suitable for products with strength requirements, especially for those that need to be plugged and unplugged when connected to sockets, as they are prone to falling off.

Low-temperature solder pasteGenerally, it is mostly usedLEDThere are many industries, and their components are mostly binary alloys. The peak temperature of reflow soldering is usually at170-190℃It is mainly used for welding radiator modules.LEDWelding, high-frequency welding, etc.
