Solder wires of our company reach GB/T3131-2001, ISO9453, JISZ3283 and USA B32-1996 standards. Depending on advanced import equitment expertise and strict test, the wires show full shiny soldered dot, clear, loe dross. Our company is a professional enterprise for producing solder material by introducing the advanced solder material production line of Germany Collin Company.And we can produce and supply the wires of Φ0.25 . There are rosin cored solder wires, no-clean solder wires and no-cored solder wires, including single cored wires, 3 cored wires and 5 cored wires, Φ0.25～Φ3.0mm.

Rosin cored solder wires made of super low impurity raw material and super rosin. Unite high technology of flux and auto-manufacture line, the wires’ingredient and property test reach GB/T3131-2001 standard. The wires offer excellent capability, reliable joints, widely used in electronic appliance and electronic household appliance. There are three types of rosin-cored wire according to different flux, including R, RMA and RA, which used in different situation.

Type	Illustration	purpose
R	no-active solder wires	minieletron, wireless radio (situation of stricting corrosion and insulation resistance)
RMA	mid-active solder wires	wireless or wires radio(situation of high insulation resistance)
RA	active solder wires	simple wireless and television(situation of quickly soldering

Flux property in GB/T3131-2001 standard:

Type	R	RMA	RA
Chlorine content(％)	Don’t sour silver test paper become white or yellowishly	<0.1	0.1—0.5
Water-solubility resistance(Ω.cm)	>1*10⁵	>1*10⁵	>5*10⁴
Insulation resistance(Ω)	>1*10¹²	>1*10¹¹	>1*10¹⁰
Rate of expansion(％)	>75	>80	>85
Dryness	Easy to wipe off dust on test block
Corruption of copperplate	Little transformation	Don’t make copper membrane has piercing corrosion	—

Non-clean solder wires CFC is restricted to use of the whole world in the " Montreal international convention", our no-clean solder wire satisfies high accuracy, high reliability of eletron products, and it reach SJ/T11168—98 standard. Moreover , it offers reliable soldering dots, clear surface, low pollution and dross.

The property of no-clean solder wire in SJ/T11168—98:

Programers	Property index
	No-chlorine	Chlorine
Acid number(KOHmg/g)	<220	<150
Chlorine content(%)	0	<0.3
Corruption of copperplate	The bronze mirror should not perforate or take off.
Flux content(%)	0.5—1.5
Rate of expansion(%)	>80
Dryness	Easy to wipe off dust on test block
Insulation resistance(Ω)	When the interval of comb is 0.3mm, >1*10¹¹
Lon pollution(µg/cm² Nacl当量)	<3

No-cored solder wires made of super low impurity raw material and super rosin, united high technology and auto-manufacture line, and the wires reach GB/T3131-2001 standard. We can offer different diameter wires to users.
Low-tin solder wires: Reducing the content of tin properly, adding other specific elements, the low-tin solder doesn’t change the physics performance, and it can reach the same soldering result, satisfy the request of lower costs.
Solder tube wires,which are coiled by semi-automatic wire winding machine, and packed in plastic tube. It is similar to rosin cored solder wires of composition and property.
Radiator-used solder of my company offers strength joint, clean surface and thermal diffusivity. We can provide products of wires or bar to customers.
