According to application scenarios, Solder Paste can be classified into Syringe-shaped solder paste and bottLED Solder Paste (also known as canned solder paste). For SMT printing, choose bottled solder paste; for automatic dispensing machine processing, choose syringe solder paste. As a Solder paste manufacturer, JJY will walk you through the differences between them:

Their ingredient formulations differ, and the actual application operations also differ. In addition, the two cannot be interchanged during soldering; otherwise, soldering quality will be relatively poor, such as solder beading or poor soldering and other defects.

Syringe-type Solder paste has a relatively fine powder, same as canned solder paste. Needle-type solder paste, on the other hand, is used for soldering with relatively small solder dot spacing.

Under normal circumstances, syringe solder paste cannot be used for SMT. Because the viscosity of syringe solder paste differs from that of canned Printing Solder Paste, and the properties are also different, using them interchangeably increases the occurrence of solder beading and poor soldering. After syringe solder paste is taken out of refrigeration, it can be stored at room temperature for a period of time and does not need to be placed in a constant-temperature device.
