Diverse applications of solder in industry
Widely used in factories and industrial zones
-
Cleanrooms for electronic components, semiconductor, and SMT productionSolder is used in the process of connecting SMD and DIP components, helping circuit boards achieve optimal electrical conductivity and mechanical strength.
-
Pharmaceutical, cosmetic, and medical device factoriesEnsures ESD compliance and cleanliness at every component connection point.
-
Laboratories, hospitals, and research centersused in research, repair, and manufacturing of biomedical devices.
-
Electrostatic Protected Area (EPA zones)Specialized solder designed to prevent interference and minimize uncontrolled electrostatic discharge.
-
Individuals and small-scale producersUsed in household electronics repair, DIY projects, or electronics technical training.
Outstanding benefits of genuine solder

Increased productivity – Safety – Production efficiency
-
Fast melting – smooth flow – strong adhesionHelps shorten soldering operation time and minimize technical errors.
-
Low smoke – No spatteringEnsures worker health and protects surrounding equipment.
-
Meets international standardsISO, RoHS, ESD, and GMP compliant, meeting strict inspection requirements in modern industrial zones.
-
Reduces maintenance costsLow oxidation, extending soldering tip lifespan and reducing the frequency of component replacement.
-
Enhances the reliability of electronic productsStrong and durable solder joints that minimize circuit breaks or contact failures caused by vibration.
Structure and design of solder product
Solder is designed in the form of compact round wireeasy to handle on soldering stations or automated production lines. The composition consists of an alloy of pure lead and tin or completely lead-free (RoHS Compliant) to minimize environmental impact.

Outstanding technical advantages:
-
Bright and shiny surface, non-corrosive.
-
Melts at low temperature (~183°C for Sn63/Pb37).
-
Does not cause oxidation of the soldering tip.
-
With or without rosin flux core, selectable based on the equipment used.
Available in various solder wire sizes ranging from 0.3mm to 1.2mm, suitable for both fine soldering work and high-power applications. Conveniently packaged in moisture-resistant spools to prevent oxidation during storage.
Instructions and precautions for using solder
Proper usage method
-
Heat the soldering iron to the appropriate temperature (~350°C).
-
Touch the solder wire to the area that needs to be soldered.ensuring even heat transfer.
-
Solder quickly and decisively, without prolonging the process. to avoid damaging or burning components.
-
Clean the solder joint with isopropyl alcohol.if necessary, to ensure cleanliness.
Maintenance and precautions
-
Store in a dry placeavoid direct sunlight or humid places.
-
Do not use expired solder. or solder with signs of surface oxidation.
-
Ensure proper ventilation in the workspace to minimize soldering fumes.
-
Do not use non-flux solder for circuits without anti-oxidation coating..
