Supporting the dissemination of environmentally friendly vehicles and their safe and pleasant drive
As part of the key growth strategies for the mid-term, the Tamura Group has been emphasizing efforts related to in-vehicle products in each business sector. In the medium to long term, we expect large growth in the demands for in-vehicle products in an environment that will be marked by the full-scale dissemination of hybrid vehicles, plug-in hybrid vehicles, and electric vehicles, further development in the use of electric equipment along with automated driving and improved safety devices, and global demand for vehicles, especially from developing countries.
【 Key component for high output of the motor: Boosting reactor for eco-friendly cars 】
For the dissemination of environmentally friendly vehicles such as hybrid vehicles, plug-in hybrid vehicles, electric vehicles, and fuel cell electric vehicles, the vehicles must be equipped with not only fuel-efficient measures but also good driving and acceleration performances, making higher output of the motor a key factor.
For that purpose, the boost converter to increase the battery voltage becomes necessary. The reactor serves as the core of this converter. In this regard, in addition to small size, low power loss, low cost, and low noise, the reactor must be highly reliable as it is mounted in the engine compartment as a power system component.
【 Prevention of solder cracks: High-heat-resistance solder alloy TLF-287 Series 】
Along with lower fuel consumption & higher functionality of vehicles, the tendency towards electronic control & downsizing/weight-saving of in-vehicle components has also been accelerated and the requirements related to their environment of use have been becoming increasingly severe.
The TLF-287 Series comprises the solder paste products that have been developed for use with in-vehicle-related electronic components. Through the introduction of a new solder alloy usable for substrates in the engine compartment that prevented solder cracks in the cold-heat cycle test under the condition of -40 °C ⇔ +125 °C, crack occurrence has been reduced by 40% compared with the conventional solder alloy and the joint reliability has been increased.
