What are the hazards caused by solder paste residues after soldering?

To meet the requirements of electronic manufacturers, solder paste producers have launchedNo-cleaning solder paste. However, in many high-precision scenarios, such as military and aerospace components of aircraft, even those with relatively weak activityRMASolder paste also needs to be cleaned to ensure its reliability. Even though it is highly active, it also brings about problems such as corrosion and leakage. Most electronic products can use no-rinse solder paste with very little residue.

Hazards caused by solder paste residues after soldering:

1Particulate pollutants are prone to cause electrical short circuits.

2Polar contaminants can cause dielectric breakdown, leakage and corrosion of component circuits, etc.

3The impact of non-polar contaminants on appearance is mainly due to the adhesion of white powder and dust, resulting in poor electrical contact.

The non-polar dirt mainly composed of rosin or other synthetic resins in the solder paste residue covers halogen, organic acids, salts, etc., playing a role of "plastic sealing", greatly reducing the corrosion of ionic dirt and avoiding leakage after absorbing moisture. During the cleaning process, the resin is washed away first. If the cleaning operation is stopped at this time, what remains on the circuit board will be ionic dirt. The consequences can be imagined. The problems caused by incomplete cleaning are far more serious than those of no cleaning at all. Therefore, once cleaning is carried out, it must be done thoroughly.
