Application of thick film technology- Heaters
May 11, 2024 | Max.
Heaters built on stainless steel substrates have been a popular choice for many applications over the past years because of their high reliability, extended lifetimes, temperature cycling, and power handling capabilities. These characteristics make them a great choice for automotive applications, and this is evident from their current use in the EV space for BMS and cabin comfort. Positive thermal coefficient (PTC) block heaters are the incumbent technology for heating applications in vehicles, however thick film heaters can handle high power density even in the smallest space available, much higher then what you could realize with conventional PTC blocks (stacked in an aluminum gasket). Thick film heaters can also run at much higher temperature than PTCs, as PTCs lose their self-controlling effect when operating at high temperatures or even degrade. Applications: Automotive: electrical vehicle battery thermal management, cabin and comfort heating, heaters for sensors in autos, incl. advanced driver assistance Industrial: food service, white goods, thermal print heads, e-cigarettes Semiconductor: wafer processing Aerospace: instrumentation, sensors Medical: analytical equipment, temperature optimization for sensors...
Application of thick film technology e-cigarette and heater
May 11, 2024 | Max.
Thick film technology is well established in the automotive industry for high reliability circuitry, challenging sensor applications, and robust passive component needs. With the evolution of electric vehicle (EV) and battery management systems (BMS), the needs for thick film materials are expanding once again. Electronic content per vehicle is doubling and tripling in comparison to current internal combustion engine (ICE) vehicles, and this will expand depending on the level of driving autonomy. One key difference comparing EV to ICE is the waste heat generation. ICE vehicles have utilized this waste heat for several purposes including in-cabin heating. However, EVs must utilize active heating systems, as the waste heat generated from the battery systems is not sufficient to fulfill the needs for cabin comfort. Additionally, battery management systems are required to provide critical temperature control for startup, operation, and charging of the battery pack. This is particularly needed for EV use in colder climates. Thick film is extremely well suited for this application because of the heating precision and repeatability, space constraints, design flexibility, and power handling capabilities of the technology. A heater is very simply a circuit with controlled resistance to output a desired temperature at a given power input. Depending on the choice of materials, thick film heaters can be self-limiting, or they can be designed with high or low temperature coefficient of resistance depending on the control systems desired. And thick film heaters can be built on numerous substrate types compatible to operating temperatures from below zero to upwards of 700°C with nearly unlimited power requirements. Most commonly thick film heaters are built on stainless steel, but there are also material systems available on polymer substrates, glass, oxide and nitride-based ceramics, and aluminum. There are long-running, commercialized uses for each of these types....
Application of thick film printing on stainless steel surface
May 11, 2024 | Max.
In this research work thick‐film manufacturing technology on stainless steel baseplates was developed. Adequate adhesion of dielectric IP211 to the steel substrate was achieved only by sand blast roughening. Standard PdAg thick‐film conductors were not solderable to IP211. The solution was to have a separate multilayer dielectric under conductors to be soldered. The reliability of soft soldering and gold wire bonding of thick‐film metallisation on stainless steel and other base plate materials was evaluated. The technology developed was applied to manufacturing an intelligent signal node. Present expertise enables the manufacture of thick‐film hybrids on stainless steel base plates. Development of an industrial production line would, however, involve considerable effort.p J7208 Perfect solution to the printing process...
