Product Description
Series fluxes are specially designed for solar energy components. With little halogen ,low solid content and high insulation impedance, the fluxes are new and environmental friendly ones dedicated to solar energy components. The products are in conformity with such standards as EU ROHS Standard, International Electrician Association (IEC)61249-2-21 halogen-free standard and EU REACH Standard.
Features
1.Dedicated to battery pieces and strip of solar energy photovoltaic components
2.Aided by the addition of high-boiling point solvent,the products can maintain excellent activityunder high temperature,so as to obtain the best effect.
3.Aided by the addition of various imported effective active agents, excellent permeability performance of the products can be ensured.
4.Low solid content, non corrosive residues residues, bright and flat lines of strip and high insulation impedance value.
5.Residues do not corrode EVA and polycrystalline silicon chips.
Application scope
Applicable to: solar energy photovoltaic components.

Instructions
| Item | Advice |
|---|---|
| Coated amount of flux | 550—950mg/cm**2
Soaking technology:550—950mg/cm2 (in solid) 400-800 mg/in**2 25-65mg/cm**2 Spray technology:400-800 mg/cm2(in solid) 25-65mg/cm**2(by flow) |
| If it is used in soaking technology: Soak the strip totally in flux liquid for two to five minutes, dry the flux liquid in the air or by preheating after taking it out . |
|---|
| If it is used in spraying or machine automatic coating technology: The strip should fully contact with flux, so as to ensure that the welding strip is completely wetted by flux. |
| Note:These above parameters are just used as reference,and it cannot ensure that the bestresultscould be gained.In view of different conditions including the equipments of users,it issuggestedthat users should adopt the experiment desigh plan to optimize parameters. |
