• Solder

The lack of suitable solder materials has previously excluded high melting point lead-free solder from serious consideration, but this is finally changing. At the same time, there is a demand for bonding materials that can maximize the capabilities of next-generation power semiconductors. Alpha Argomax sinter paste is a bonding material that can meet both of these challenging requirements. We are also focusing on the development of high thermal conductivity epoxy paste. The demand for improved reliability and cost-effective high-volume manufacturing (HVM) of die attach has never been higher. With environmentally friendly Argomax technology, it is possible to create low-pressure sintered die attachments based on highly engineered particles. Argomax creates silver bonds with very high thermal and electrical conductivity, providing high reliability and flexible bonding lines. It enables the manufacturing of SiC/GaN power modules/devices with a Tjmax of over 200°C, contributing to improved reliability of chip bonding and reduced total costs. It can also accommodate the lead-free transition for high-reliability bonds. We offer a variety of pastes, films, and preforms tailored to specific applications.

ELT SENSOR is a South Korean manufacturer specializing in sensors, with numerous achievements in various research institutions and the agricultural sector. They develop high-precision, compact modules through their proprietary technology. One CO2 sensor can measure CO2 levels in an area of 100 square meters (such as classrooms or large conference rooms). It can also be installed on walls to prevent loss or dropping. It has been proven that when indoor CO2 levels reach 2500 ppm, human performance, including decision-making, significantly deteriorates. Symptoms such as fatigue, drowsiness, headaches, and nausea may occur, and proper ventilation can prevent CO2 levels in offices, conference rooms, stores, and classrooms from exceeding 1500 ppm. *The model featured is a product that displays CO2 levels. Demo units are available for loan.

Gas Discharge Tube (GDT) surge arresters operate as voltage-dependent switches. When a voltage exceeding the rated DC breakdown voltage is applied across the device, the gas inside the GDT begins to ionize and discharges until it reaches the impulse discharge initiation voltage. At this point, the device is fully in the "on" state, maintaining a low arc voltage regardless of the discharge current. Once the transient current passes, the GDT returns to a non-discharge state. GDT technology can handle extremely large surge currents, has very high insulation resistance in the off state, and very low capacitance, making it ideal as a standalone protector or as an initial means of protection in multi-stage circuit designs. Bourns offers a wide range of 2-electrode and 3-electrode GDTs, as well as the new innovative FLAT GDT series. The 3-electrode version, chosen for its higher reliability and safety, features a uniquely developed switch-grade fail-short function. Bourns' GDTs protect power and communication lines from lightning surges.
