in harsh environments

Flexible electronic components from WECO
withstand extreme environmental conditions

Gravel roads in the desert, icy tracks in the Arctic or extreme weather conditions in the tropics – commercial vehicles have to be tough. This is especially true of the electronics installed in the new generation of power packs. Surface mount technology (SMT) with floating elements.
Connector Technology
For vehicles that are operated at extreme temperatures, it is necessary for a transmission to function perfectly over a wide temperature range
The automotive sector places special demands on the printed circuit boards used in vehicles. In the commercial vehicle sector, the conditions are even tougher. The electronic components have to be robust to keep the wheels rolling, even on rough terrain. Another aspect is the environment. Whether it is sandstorms, freezing rain or high humidity, the vehicles must be able to withstand the sometimes extreme environmental conditions for many years. In vehicles that operate in extreme temperatures, a transmission unit has to function smoothly over a wide range of temperatures. In the Siberian winter, for example, outside temperatures of minus 40 degrees Celsius are not uncommon. The operating temperature of the transmission oil, on the other hand, can rise to 90 to 100 degrees Celsius. The integrated system must be able to withstand these fluctuations without any problems. Floating pin technology has proven itself in unforgiving outdoor environments. This robust technology operates in all weathers and is reliably in heat, rain, sleet, and snow. It is also impervious to gear oil, gases, and other chemicals. High strength and coplanarity ensure a long service life, which is a basic requirement for use in vehicles.

Ready for SMT

The products are based on surface-mount technology (SMT), which is now a firm favourite in automotive electronics. SMT scores points not only for its flexibility, but also for its high cost-effectiveness. However, classic SMT components are also reaching their limits in the automotive industry.
Up to now, this has been the case for connectors above a certain size and with a pitch of more than 2.54 millimetres. In these cases, through-hole mounting was still required in order to attach the components to the PCB. The reason for this is that the conductor connection and the power supply need sufficient dimensions to meet the physical requirements for higher currents and voltages.
