Product Details
Metal‑insulated substrates excel in mid‑ to low‑voltage thermal management and offer exceptional cost‑performance, making them essential base materials for automotive OBCs, DC‑DC converters, and LED lighting driver boards.
Compared with FR‑4 substrates, the metal‑based substrate delivers more than tenfold improvement in thermal dissipation, effectively preventing high‑temperature failures in auxiliary electronic control components.
Compared with ceramic substrates, procurement costs are reduced by 60%, and the material offers significant weight‑saving benefits, making it well suited to compact automotive mounting architectures. It is widely used in automotive electronics and charging stations.
Our company maintains in-stock standard‑thickness aluminum‑based substrates and thick‑copper‑based substrates, enabling rapid fulfillment of customers’ circuit etching and surface‑treatment requirements.
The product has undergone automotive‑grade moisture‑proofing and high‑voltage testing, ensuring compatibility with the vibration and humid conditions typical of vehicle environments. Balancing cost efficiency with automotive‑grade reliability, it is well suited for use in auxiliary electronic control systems where cost reduction is a key consideration.
