multicore

The fluxes in HARIMA’s cored solder wire products accommodate a wide variety of different alloys, cores, and diameters. MULTiCORE cored wires support both traditional tin-lead manufacturing, as well as modern Pb-free processes, including point-to-point robotic soldering. MULTiCORE cored wire ensures even distribution of flux throughout the wire and is available in Pb-free, high reliability 90iSC alloy, SnPb, and halogen-free formulas. For assemblers who prefer a non-cored option for selective soldering applications, MULTiCORE solid wire products are offered in both Pb-free and SnPb options.

Solder wires have an extensive set of uses in a broad range of industries ranging from consumer electronics to industrial bonding of metal substrates. To ensure flexibility across all applications, our lead-based and lead-free solder wires offer:

Broad range of melting points
Durable mechanical bonding
Range of diameters

Manufacturers relying on high-quality solder wire and fluxes can trust HARIMA’s range of products to meet the challenges they face within both existing and newly developed processes. For instance, when developing modern automotive electronics where durable mechanical bonding is balanced with reliable electronic connection or improving the environmental safety within automated production lines of consumer electronics, HARIMA can help you develop more efficient and cost-effective systems.

HARIMA’s Solder Wire Solutions

Available in a broad range of formulations, choosing the correct type of solder wire for your application is paramount to successful assembly and efficient manufacturing.

Conventional soldering wires usually consist of tin-lead alloys. However, HARIMA also offers lead-free solder wire including SAC alloy and 90iSC alloy. These are commonly used in areas where sustainability and compliance with REACH and RoHS is needed. While they often have a higher melting point, the addition of nickel to certain formulations helps to mitigate this limitation.

Cored Wire

HARIMA’s multiple flux core technology in our cored wire options distributes flux evenly throughout the solder wire, offering fast wetting and high solder joint reliability. Used in all types of electronic assemblies, cored wire consists of a hollow solder wire filled with a flux core to aid efficient soldering processes. MULTiCORE cored wires are ideal for use in robotic soldering, repair, or reassembly of devices. HARIMA’s MULTiCORE cored wires provide a number of different products suited for individual needs.

Usually, solder wire with flux features either an acid core or a rosin core and can be combined with lead-based or lead-free solder wire HARIMA also offers halogen free formulations as flux inside the wire.

Solid Solder Wire

Used as both a mechanical joiner in the plumbing industry and on PCB boards within the electronics industry, alongside a broad range of other applications, solid solder wire requires a separate flux in order to be used in either manual or automated processes. Like solder wire with a flux core, solid solder wires can be found with either lead-based or lead-free alloy wires.

Thin Solder Wire

Thin solder wires are most commonly used within electronic assemblies where precision soldering is required. The small diameter of these wires allows precision feeding into tight areas where the solder joint is required. They may or may not also include a built-in flux core and they are available in both lead-based and lead-free formulations.

Solder Wire Application Areas

The application areas for the various solder wire types are numerous. Here, we look at the main ways in which solder wire is used:

Manual Soldering

Manual soldering is used where hand soldered components and assemblies are required. Used most commonly in applications where precision is required on short runs, manual soldering is also useful in the repair and rework of products. Ensuring you have the right type of solder wire for this technique is crucial to the success of any device or component.

Battery Soldering

With the rise of electrical vehicles, battery soldering has become more important than ever. Ensuring the right type of solder wire and flux is used for your application is important to ensure reliable connection and mechanical strength across a broad range of industries. HARIMA offers 90ISC alloy in cored and solid wire to achieve highest solder joint reliability.

Robotic Soldering

Automated processes using laser soldering have become increasingly popular as manufacturers scale up and increase efficiency on production lines. Robotic soldering ensure precision on fine pitch and high density boards, allowing contact-less operation on the circuit board.

Industrial Applications

While solder techniques are used within many industries, today, both the automotive and consumer electronics industries are highly dependent on high-quality solder wires.

Automotive

Solder wires used within the automotive industry for electronic control units and harnesses need to fulfill a broad range of tasks. Reliable electrical connection, high-mechanical strength and corrosion resistance are also crucial to the reliability and efficiency of any vehicle and its associated components. HARIMA offers 90ISC alloy in cored and solid wire to achieve highest solder joint reliability.

Electronics

The consumer electronics industry represents a high demand for all types of solder wire. Both lead-based and lead-free solder wires are used, with the latter becoming increasingly popular as the technology advances and environmental restrictions become increasingly prevalent. Additionally, as devices become increasingly miniaturized, robotic soldering techniques are developing quickly, and ensuring you have the right solder technologies for production lines is paramount to cost efficiency and maintaining high standards. This is especially important in the telecom and datacom industry.
