Solders for Electrical Engineering – Precision, Conductivity and Stability
LOT-TEK provides solder alloys, wires and preforms for electronic assemblies and circuit boards
In modern electronics manufacturing, soldering remains the key technology for creating electrically conductive and mechanically reliable connections. Whether in PCB assembly, semiconductor packaging or sensor integration – LOT-TEK offers customized soldering solutions for electrical engineering that meet today’s process and quality standards.
For most applications in electronics, low-melting solders are preferred to avoid thermal damage to sensitive components. Common choices include copper-, nickel-, and silver/copper-based alloys, widely used for soldering circuit boards, bonding pads, plated through-holes and SMD components.
In addition to solder wires and pastes, LOT-TEK offers preforms and precision wires specifically designed for manual and automated production. This ensures consistent results with low contact resistance and excellent long-term reliability – even under dynamic mechanical or thermal load.
Our solder materials are available in tin, zinc, copper, aluminium, silver and gold, either as pure metals or optimized alloys. Depending on your application, we offer the right formulation – whether for large-area bonding, selective micro soldering, or thermally robust connections.
Bonding wires for semiconductor applications
In semiconductor electronics, fine wire bonding is the standard method for creating electrical interconnects. LOT-TEK supplies bonding wires made from copper, aluminium, silver, gold and platinum – all tailored in terms of diameter, tensile strength and metallurgical purity.
These wires are used in thermosonic, ultrasonic or thermocompression bonding and must meet demanding requirements for flexibility, conductivity and process consistency. LOT-TEK helps you select the right material and provides documentation and process guidance as needed.
Our products are used across all fields of electronics – from consumer devices to industrial systems, and even in medical electronics and sensor-based tools.
