DPC Metallized Ceramic Substrate

By -

DPC ceramic substrates are an ideal material for growing VCSEL laser diodes due to their high thermal conductivity, low thermal expansion coefficient, and excellent mechanical properties. The direct bonding process used to create DPC substrates ensures that the copper layer is tightly bonded to the ceramic layer, providing excellent thermal management properties.

In addition, DPC ceramic substrates have a coefficient of thermal expansion (CTE) that is well-matched to the epitaxial layers of the VCSEL laser diodes. This ensures that the diodes remain stable and reliable over a wide range of temperatures, making them suitable for use in a variety of applications.

Using DPC ceramic substrates can also improve the performance of VCSEL laser diodes by reducing the threshold current and increasing the output power. This is due to the excellent thermal management properties of the DPC substrate, which can dissipate heat more efficiently and prevent thermal runaway.

In summary, the use of DPC ceramic substrates in VCSEL laser diodes offers many advantages over traditional GaAs substrates, including improved thermal management, reliability, and performance. As the demand for high-speed, low-power laser diodes continues to grow, DPC ceramic substrates will become an increasingly important component in the production of VCSEL devices.

Source: https://www.innovacera.com/news/ceramic-heater-coil-for-vaporizer.html Not every dry herb vaporizers are the same! Especially those used ceramic heating element. The ceramic heating element is a safety and healthiest option for dry herb vaporizers, so every vaper is preferred to choose those vaporizers that carry ceramic heating element. The proponents believe that the heating element is the core of the vaporizer and primarily dictates the experience of the taste. Let's more specific, when a vaper burns tobacco, marijuana, or hemp during traditional smoking to release the active component, whatever it's nicotine, CBD, or THC, they inhale the smoke. We all know that's not good for health. Rather than burning, Vaporizer heats the liquid, wax or even dry herb to release a vapour, and a vaper inhales the vapour without any damage to their lungs or throat. And why the ceramic heating element is becoming the core part of the vaporizer? It's mainly because: 1. Ceramic
