Soldering pastes

Optimal performance: printability, reflowability, and weld joint reliability

HARIMA's 90iSC solder pastes, stable at room temperature and highly reliable, are renowned for their ease of application, performance, and dependability. MULTiCORE brand soldering materials are guaranteed conflict-free and ensure durability thanks to temperature-stable, halogen-free flux chemical platforms. They enable robust electrical interconnections, essential for modern electronics.

With no intentionally added halogens and incorporating the purest raw materials available, HARIMA's halogen-free formulations are, in fact, halogen-free.

Welding accessories

Accessories and cleaning products for welding that allow for the quick and efficient reworking of weld joints.

Because even the best welding processes can require touch-ups, HARIMA offers a complete range of accessories and cleaning products for fast, durable, and reliable resurfacing of weld joints. From desoldering wicks and welding masks to soldering kits and residue removal cleaners, HARIMA resurfacing solutions help preserve valuable components for reuse.

Soldering flux materials

Offering high-performance, flawless welding and excellent flow rate

HARIMA offers a range of liquid fluxes that facilitate lead-free and SnPb wave soldering, selective soldering, rework operations, and laser soldering. HARIMA liquid fluxes are environmentally friendly and part of a sustainable production approach.

HARIMA liquid fluxes offer exceptional performance, ensuring smooth solder flow while cleaning and purifying components.
Their advantages include:

- Exceptional soldering performance
- Electrical safety, high surface insulation resistance (RIS)
- Minimal residues
- Suitable for a wide range of applications and metallic substrates
- For automated wave and selective soldering processes

In any soldering application, manufacturers can encounter various challenges, particularly depending on the specific application. Cleaning and purifying the joints are essential to ensure the accuracy of consumer electronics components. Furthermore, soldering fluxes contribute to the high mechanical strength of the joints, a significant advantage in automotive applications where resistance to vibration and shock is paramount.

HARIMA supports manufacturers in addressing these challenges with a range of high-quality fluxes suitable for all applications and industries. Whether you use lead-free or lead-based solder, our soldering flux offers exceptional workability in both manual and automated processes.

Soldering wires

Award-winning wires for robotic welding, rework, and manual welding operations

The fluxes used in HARIMA flux-cored solder wires are compatible with a wide variety of alloys, cores, and diameters. MULTiCORE flux-cored wires are compatible with traditional tin-lead manufacturing processes, as well as modern lead-free processes, including robotic point-to-point soldering. MULTiCORE flux-cored wires ensure homogeneous flux distribution and are available in lead-free, high-reliability 90iSC alloy, SnPb, and halogen-free versions. For assemblers who prefer a coreless solution for selective soldering applications, MULTiCORE solid wires are offered in lead-free and SnPb versions.

Solder wires have numerous applications across a wide range of sectors, from consumer electronics to industrial bonding of metal substrates. To ensure optimal flexibility in all applications, our leaded and unleaded solder wires offer:

- A wide range of melting points
- A durable mechanical connection
- A range of diameters

Manufacturers using high-quality solder wires and fluxes can rely on the HARIMA product range to meet the challenges of their processes, whether existing or under development. For example, in the development of modern automotive electronics, where a durable mechanical bond must be combined with a reliable electronic connection, or in improving the environmental safety of automated consumer electronics production lines, HARIMA helps you design more efficient and cost-effective systems.
