Applications
Consumer・Industrial products
Trends in both industries
In today‘s market, consumer products are increasingly designed with multifunctionality and miniaturization to better suit our modern lifestyles. In contrast, industrial products are evolving through the implementation of automation and robotics in factories to address labor shortages, enhance work quality, and ensure worker safety. Furthermore, a temporary stoppage of equipment or production due to any kind of trouble would result in serious losses, so industrial products require high product reliability.

Challenge for surface mounting production
Consumer product
-
Cost-saving
Along with price competition intensifying for the products themselves, there is a corresponding demand for cost reductions in soldering materials.
-
Miniaturisation of on-board components
As major household appliances become more multifunctional and compact, their components are becoming increasingly miniaturized.
-
Halogen-free
The demand for environmentally sustainable, halogen-free products is expanding beyond specific products and categories.
-
Reduction in VOCs
Reducing VOCs is also essential in environmental sustainability.
Industrial product
-
High durability performance
High durability of the solder is required for devices that generate heat or are used in harsh environments(high⇔low temperature)
-
Heat dissipation measures
Components such as power transistors, which generate high temperatures during use, require effective heat dissipation measures.
-
Dew, Condensation resistance
Products used outdoors should continue to operate in environments with condensation, temperature fluctuations, and humidity changes.
Therefore, appropriate measures need to be taken. -
High electrical reliability
Solder joints with components, particularly those integrated into plant and equipment boards, must ensure high electrical reliability even under harsh conditions.
Countermeasures against soldering defects
Examples of major defects, which are common to both consumer and industrial product
-
De-wetting on electrode
-
Unmolten solder
-
Voiding under bottom –electrode-components
-
Solder・Flux splattering
-
Decrease in first pass yield of ICT
