Core Flux Type

Flux –Cored Type Features Cleaning Method
Water Soluble EM#17 High activity water washable cored-flux for repairing through-hole, mixed and surface mount assemblies. More effective comparing to rosin fluxes in soldering difficult-to-solder metals such as brass, nickel and severely oxidized copper. Water clean
No-Clean EM#26 Lowest and clear flux residue suited for most commercial no-clean hand soldering assemblies. Widely and most popular choice for assemblies requiring no-clean, clear residue characteristics. No-clean
No-Clean EM#53 Fast wetting action RA cored-flux for consumer electronics assemblies. Flux residue is neither corrosive nor conductive under normal condition of use. Cleaning not necessary for most consumer assemblies. Bi-polar solvents
No-Clean Halide free EM#23N Halide free with lowest and clear flux residue suited for no-clean hand soldering assemblies. Exhibit fast wetting characteristics. Widely and most popular choice for assemblies requiring no-clean, clear residue characteristics. Suitable for use on different alloys. No-clean

No Clean Halogen Free*3
EM#71

Halogen free with clear flux residue suited for no-clean hand soldering assemblies. Exhibit good wetting characteristics. Widely and most popular choice for assemblies requiring no-clean, clear residue characteristics. No-clean

No-Clean Halogen free*3
EM#79

Halogen free with clear flux residue suited for no-clean hand soldering assemblies. Exhibit good wetting characteristics. Widely and most popular choice for assemblies requiring no-clean, clear residue characteristics. No-clean

LF-303W / LF-307W / LF-315W Fine Wire

With enhanced technology in fine wire manufacturing & new cored flux chemistry, we are proud to introduce our 0.17mm lead free wire.

This is suitable for soldering in micro electronics application requiring precision & fine pitch soldering.

LF-302W Low Temperature Wire

Electroloy has developed new capability to extrude Sn/Bi low temperature solid lead free wire. The Sn/Bi ( LF-302W ) low temperature wire has a melting point at 138°C. The diameter ranges from 0.5mm to 2.0mm to suit the needs of various process application for temperature sensitive soldering.

 

Special Solid Wire

Electroloy has successfully produced special lead free alloy, for example, Sn/Zn, Sn/Ag/Sb and Sn/Bi used in customized and preform application in the form of Ribbon/Wire/Rectangular.

Other hard to draw and non-ductile alloys like bearing alloys, indium and bismuth based fusible alloys can also be requested.
