【 JJY 】 Washable Solder paste - Water-soluble solder paste

Solder pasteIt is a common welding material, and inSMTThe mounting industry is widely applied. The two main types of solder paste are "no-clean solder paste" and "washable solder paste". Currently, most of the solder paste products available on the market are no-clean solder paste. We won't elaborate on this type of solder paste today. Now, Shenzhen JJY Solder Paste Manufacturer will talk about today's main character, "washable solder paste:

"Washable solder paste", as the name suggests, is a type of solder paste that can be washed with clean water. It is also known as water-soluble solder paste. The most prominent feature of this type of solder paste is that it is washable.

Washable solder paste refers to the process of soaking the circuit board in clean water or alcohol after the soldering process is completed5~6After minutes, clean the residue on the circuit board thoroughly with a brush, and then rinse it once. Use it again after the cleaning process is completed65-80One of the methods of "water washing" is to dry the circuit board with hot air or let it air dry naturally. In addition, a water cleaning machine can also be used for cleaning. The general cleaning principle is to first rinse with warm water, then with ionized water, and finally use an air knife to blow the circuit board clean.

Washable solder paste is generally required to be cleaned within four hours after the circuit board is soldered. Otherwise, there may be white powder-like residues that cannot be cleaned thoroughly. Therefore, most manufacturers require that the circuit board must be cleaned within four hours.

After the washing type solder paste reflow soldering is cleaned, the solder joints on the circuit board will be very bright and the board surface will also be very clean.

Washable solder paste is suitable for scenarios with high cleanliness requirements. Its cleaning speed is much faster than that of rosin solder paste. Except for the need to strictly control the ambient temperature and soldering temperature during use, other usage methods are similar to those of non-washable solder paste. The main models of washable solder paste from our company, JJY Solder Paste Factory, are:TLP-JJY3WR-62362T4,TLP-JJY3WER1-6337T4,LFP-JJY5RW-305T4,LFT-JJY5RW1A-4258T3Wait a moment.
