What are the characteristics of lead-free and no-clean solder paste?

We know that currently, there are three types of solder pastes on the market based on different fluxes: rosin solder paste, washable solder paste, and no-clean solder paste. Among lead-free solder pastes, lead-free no-clean solder paste is favored by many technicians in factories. So this kindLead-free and no-cleaning tinWhat are the characteristics of the ointment?Now, Shenzhen JJY Solder Paste Manufacturer will analyze for you the benefits of lead-free solder paste that does not require cleaning:

Washed solder paste:Water-washed solder paste uses water-soluble flux. After welding, the residues are prone to react with water, which may invade the circuit board or cause a short circuit due to moisture. Therefore, they must be cleaned. After soldering, soak the circuit board in water or alcohol5After minutes, clean the residue with a brush and then rinse again. After cleaning, use60-80Dry the circuit board with warm air or let it dry naturally.

No-cleaning solder paste: After soldering,PCBThe surface of the board is relatively smooth and has little residue. It has passed various electrical performance technical tests and does not require further cleaning;The flux residue of this solder paste is not easy to combine with water,Even after getting damp, its insulation resistance value is still very high,There will be no short circuit phenomenon or substrate erosion phenomenon.So there is no need to clean..

When compared in this way, the advantages of lead-free no-wash solder paste become very obvious: no need for cleaning, safe and convenient, time-saving and improved work efficiency.

Lead-free and no-clean solder paste is specially designed forSMTA kind of no-wash low-odor solder paste produced uses a special artificial rosin and additives, which makes the solder paste have very little solid residue after reflow soldering and achieves excellent soldering results.
