Solder flux market is projected to record a substantial growth rate over the coming years owing to the rising demand from various applications such as consumer electronics, and automotive among others. Solder flux is a type of chemical utilized in automatic hand soldering and PCB assembly. It is generally utilized to clean the surface of PCB before the soldering process. It helps clean as well as eliminate oxides and other impurities, thereby helping in wetting. Solder flux further helps in de-oxidizing the metals such as leads of electronic components and copper tracks on the PCB, thereby helping in better wetting and soldering.

There are numerous factors which help in determining the type of flux to be utilized during soldering such as the process of soldering like SMT, hand soldering, or wave soldering; type of PCB whether multilayer, double-sided, or single-sided. Solderability of metals to be combined, type of active or passive electronic components to be soldered and density. The solder flux is further available in various other forms like solid flux, flux paste, flux pen, and liquid flux.

The solder flux market is segmented in terms of product, sector, and regional landscape.

With respect to product, the solder flux market is categorized into no-clean, water soluble, and rosin-based. Among these, the no clean solder flux is expected to witness the highest growth rate during the forecast timespan. It eradicates the need of surface cleaning and reflow and can allow for low preheat process.

The properties and behaviors of no-clean fluxes might differ substantially which is dependent on their specific chemical composition, like for instance some of the no clean fluxes leave an enormous amount of residue, which is unappealing.

In terms of sector, the overall solder flux market is classified into telecommunication, automotive, consumer electronics, and others. Telecommunication sector will register a market share of around 30% by the end of the forecast timeframe. Increasing globalization and rising need for better communication services will drive the need for better telecommunication services. Soldering is a common process in PCBs, and is utilized in telecommunication equipment like high speed routers & servers, phone switching systems, cell towers, etc. Thus, upsurge in these devices drives the need for solder fluxes in soldering of communication PCBs.

From a regional frame of reference, Asia Pacific solder flux market will account for around 70% of the market share over the forecast time period. The region accounts for majority of the market share in global electronics industry with China leading the way. In addition, the region also has strong electronics manufacturing capabilities.
