BBIEN is willing to work with you in good relationships to refine the performance lead-free solder .
1．Little impurity, diffusion capacity well
2．Weldability, good fatigue resistance
3．Solder joints, solder surface brightness, good wetting
4．strong antioxidant, anti-creep
  5．Increase production speed, reduce production costs
 

The voice of Prohibiting the use of leaded products growing, lead in solder is to bear the brunt.Followingthe spirit of professional and carrer,we will create a new microelectronic welding era and devote ourselves to the “lead-free”of world electronic products together wit you sticking to market-oriented and aiming of technological creation an environmental protection.Now the lead-free solder wire include,Sn99.95,SnCu,SnAg,SnAgCu and SnBi,Sn-In,Sn-Zn,Zn-Cu,Ag-Ni...

Core Wire is manufactured from grade-A virgin metals that meet or exceed IPC, ANSI/J-STD-006 and ASTM B32
standards. Wire solder is available with 1.1,2.0 2.2 & 3.3% flux core. BBIEN lead free no clean core wire solder is available in many alloys, including lead-free and tin lead formulations. Our core wire is packaged in one kilogram per roll. Other packaging is available upon request.

BBIEN environmetal cored solder wire are developed to comply with the IEC and JPCA halogen content specifications, complying with the recent trend for environmental protection.   Lead free solder wire also apply for the highest industry standards for electro-chemical electonics.
Its reliability and is very fast wetting with low flux spatter, setting the new standard in performance and reliability.
Its clear non-tacky residue does not require cleaning, and its excellent joint appearance allows for easy inspection.   also generates a low amount of fumes, thus creating a clean and operator friendly working environment.

BBIEN's lead free core wire solders are available in the standard SACX305,0307 alloy, other industry standard lead free alloys and in the BBIEN SACX Plus® low Ag alloys that offer excellent value versus the higher cost of higher-Ag alloys.

The tin solder wire could be classified as reel packing and tube packing type.
Each can/bottle holds the solder wire is 500g;
Each tube can load the solder wire is 13g/piece
