What are the advantages and disadvantages of low-temperature solder paste? -- JJY Solder Paste Manufacturer

Low-temperature solder pasteWhat are the advantages and disadvantages? The main reason for the application of low-temperature solder paste is that the product design cannot withstand the conventional temperature requirements and uses low-temperature solder paste for the soldering process. It serves to protect the components that cannot withstand high-temperature reflow solderingPCBVery much.LEDIt is welcomed by the industry. Its alloy composition is tin-bismuth alloy. The peak temperature of reflow soldering for low-temperature solder paste is170-200℃.

Low-temperature flux paste is a no-clean type of flux paste designed for the current rapid soldering process, using tin and silver X This series is made by stirring low-melting-point aluminum alloy-free welding powder and low-temperature flux paste, and is suitable for laser rapid welding machines and equipment HOTBARThe shortest welding time can be achieved 300 ms. This product rapidly evaporates the active solvent coating throughout the entire welding process. After welding, there are no residual tin beads, completely eliminating the process of removing tin beads. Meanwhile, this product belongs to the zero-halogen bulb secret recipe, with very little organic chemical residue and a transparent appearance.
High surface characteristic impedance and high stability; It can be integrated into various processing techniques such as automatic dispensing machines, printing and needle transfer.

Advantages of warm solder paste:

Low-temperature solder paste is suitable for low-temperature soldering processing technology and is less likely to damage or burn the original components of electronic devices. Low-temperature solder paste printing has strong working ability and is easy to solder in Wuxi City. It is widely usedSMTLow-temperature solder paste can be printed continuously24In hours, increase the total output of your company's goods.

When surface mount components cannot handle it200℃When the temperature above and the surface mount reflux processing technology is required, low-temperature solder paste should be used for the soldering process. The maintenance cannot withstand the high-temperature reflow soldering furnace for welding the original andPCBVery much.LEDThe field warmly welcomes you and is particularly suitable for those with high powerLED,LEDPackaging, etc.
Utor low-temperature solder paste selects a unique flux formula, solving the problem of containingBiThe characteristic of tin-like powder being prone to air oxidation makes it highly solderable. It can produce good wetting on the aluminum electroplated nickel welding surface, has a long service life during continuous printing, and leaves little residue after welding,High stability.

Defects of low-temperature solder paste:

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

2The solder joints are very sensitive and are not suitable for products with standard compressive strength, especially for those that must be plugged into a power socket when connected, as they are very likely to fall off.
