Photovoltaic flux
产品概要:
-Non wash soldering flux for solar photovoltaic modules, compliant with environmental regulations such as EU ROHS, REACH, and halogen-free IEC 61249-2-21
-High wettability, adding multiple imported high-efficiency activators to ensure excellent welding penetration performance; Solved the problem of insufficient activity caused by solvent evaporation of the flux after soaking the interconnect strip in flux for a long time. -During pre welding and post welding operations, the substrate and parts do not produce corrosiveness and require no cleaning.
-Very little residue, no cleaning required after welding, in compliance with IPC J-STD-004 standard.
-High surface insulation resistance can be tested through rigorous copper mirror, copper plate corrosion testing, and surface insulation impedance testing, ensuring safety and reliability.
-The solder strip will not cause yellowing in the components, making it an ideal choice for photovoltaic solder strip products.

Fluxes help and facilitate the soldering process while providing protection against oxidation of chemicals. Jinhongtai flux is carefully formulated with imported film forming agent, high-efficiency active agent and organic activator, and has a large range of selectable process parameters, so that it can adapt to different environments, different equipment and different process conditions, and has excellent performance in the application fields of spray or foaming wave soldering and manual dip soldering. At the same time, the circuit board after soldering the flux has a high surface insulation resistance, which can ensure the safety and reliability of the electrical performance of the circuit board.
1. Product introduction
Our photovoltaic fluxes are carefully formulated with imported film formers, high-efficiency activators and organic activators, which can be widely used in the welding of solar photovoltaic materials.
The activity of the flux system is specially designed, in which the appropriate amount of solids content and its internal activity mechanism ensure that the solar photovoltaic material has very little residue after welding, and the surface of the material is dry and clean, which meets the requirements of IPC standards for cleanliness. In the absence of special requirements, the cleaning process can be eliminated, thereby saving the manufacturer's production costs. At the same time, this series of fluxes has high wettability, and can effectively solve the problem of insufficient flux activity after solvent volatilization caused by the long-term placement of the interconnection strip after soaking the flux in the interconnection strip, which is an ideal choice for photovoltaic welding tape products.
2、Scope of application
This series of fluxes is suitable for the welding of solar photovoltaic materials such as solar photovoltaic welding tapes, non/mono/polysilicon modules, elastic soldering tapes, photovoltaic string photovoltaic welding tapes, etc.
Applicable process: spray, adhesive coating, can be suitable for single-wave operation.
