Rosin‑based Flux
Rosin‑based flux is widely used in conventional PCB assembly, through‑hole soldering, repair of general discrete components and cost‑sensitive general‑purpose electronic soldering applications.
Overview
Rosin‑based flux takes natural rosin as the main active carrier and is formulated with organic‑acid activators. It represents a highly versatile traditional flux system.
Applicable Processes
Compatible with wave soldering, manual soldering‑iron soldering, conventional reflow soldering and simple packaging with pre‑formed solder foils.
Core Advantages
Excellent Wetting Performance
Rapidly removes metal oxide layers and delivers stable tinning performance during soldering.
Well‑established Formulation
High cost‑performance and compatible with all common solder materials.
Anti‑oxidation Protection
Rosin forms a protective film upon cooling, providing short‑term air barrier to prevent solder‑joint oxidation.
Suitable for Small‑batch Operations
Ideal for medium‑and‑small‑volume production, repair and prototyping. Low operating threshold with easy‑to‑implement supporting cleaning processes.
