Product Features:

1. Raw material

(1) copper matrix: Select high-purity  T2   copper(resistance0.0174μΩ·m), by  using  nice  slitter and perfect annealing  process  makes our products low resistivity, high scalability and low rate of fragment   in the mean time.

(2) tin alloy: The specialized formula solders material(melting point 183°C- 227°C),ensures not only chemistry with better electrode, but also  great  physics characteristic. The product is highly resistant to creep, fatigue and high temperature. It ensures high reliability of better works.

(3) soldering fluxes :non-cleaning flux  with  low  solid  content  is  strictly used, and  no halogen elements is  contained,  It won’t tum  yellow  or  black in high temperature and high-humidity experiment.

2. Appearance

The tin copper strip has good surface finish and uniform color. There’s no defects such as copper-leakage, Tin-remove black spot, corrosion, crack, scar and so on.

3. Dimension tolerance

Thickness on thickness:±0.05mm

Tolerances on width: ±0.05mm
