Type 7 SAC305 powder instruction

BBIEN’S LF-05 SAC305(SN96.5Ag3.0Cu0.5)is a lead-free,tin silver copper alloy solder powder designed for applications where residue with excellent pin testing property and ability to pass JIS Copper Corrosion test are required.The melting point of SAC305 is 217degree Celsius.Packing with 1kg and 5kg per vacuum bag filled with nitrogen.

Availability size of powder:

Available type:it is available in Sn96.5Ag3.0Cu0.5 type 3 powder mesh is normally recommended, but type4,type5, type6 and type7 are all skilled and available for this alloy solder paste.

BBIEN’S LF-05 SAC305(SN96.5Ag3.0Cu0.5)solder powder is available for fine pitch applications with SnAgCu alloys in a similar melting range to the listed alloys,for specific packaging information.

Sn96.5Ag3.0Cu0.5 tin silver solder powder,the following size of powder can be available
Small variations in composition and the level of impurities can affect wetting properties of the solder paste:oxidation behavior, melting temperatures,flow within the joint and joint strength. The ideal solder composition will feature tight tolerances of alloy composition

BBIEN SAC305 silver solder type7 to type3 powder is a synthetic poly-adduct designed to exceed requirements for reliable solder joints in SMT PC board assemblies.

Storage,Handling,and Shelf Life:

Recommended optimum storage condition for solder powder to maintain consistent viscosity,reflow characteristics,and overall performance.BBIEN’S SAC305 should be stabilized at room temperature prior to printing. BBIEN SAC305 should be kept at standard refrigeration temperatures, 20~28°C.Please contact BBIEN,if you require additional advice with regard to storage and handling of this material.Shelf life is 6months from date of manufacture and held at 20~28°C

BBIEN LF-05 SAC305 powder feature

Powders are divided into six or senven particle type with the finer powder represented by higher numbers.Table 1 also includes the customary designation of powders by mesh sizes of the sieves used to sort the particles according to ASTM B-214 Test Method
1.The welding powder is ball shaped,the dark part is a tin rich area and the light part is a lead rich area.The pictures show the good sphericity,homogenous alloy composition and smooth surface of the product.

2.Particle size classification and final typing technology enables stable particle size of the product provided to customers.

3.SAC305 type7 silver powder has low oxygen content oxygen content is strictly controlled during production and packing of allalloy welding powder.Leco oxygen determinator is adopted to determine the surface oxygen content and chemical assay is adopted to determine the total oxygen content.

4.Advanced powder classification and collection technology enables Type 4-Type 3 alloy welding powder free of powder smaller than 20um.

Packing Details:
The packing materials can be separated into inner layer vacuum bag and outer package with plastic barrel,so as to better secure for shipping and transportation.
