MHE is the abbreviation of Micro Heat Exchange, which it is Rayben's unique thermal substrate with independent intellectual property rights. The MHE series include MHE®301, MHE®601 and MHE®901. The MHE®301 is a metal substrate with a thermal column designed for high heat thermal requirements. MHE®601 is dedicated to COB. MHE®901 is a composite structure of ceramic or other high thermal conductivity dielectric and FR4, which can be widely applied to power device carrier boards such as LED, MOSFET, IGBT, etc., and effectively solving the heat thermal requirement.
Yes, we are committed to providing RoHS compliance products.
Yes, we have our own certified ENPIG line.
No, Rayben doesn’t provide SMT services.
MHE®301 is a special metal substrate. Its design concept comes from metal direct conduction. It utilizes the special manufacturing process and technical advantages of PCB to make heat more direct and faster.
The normal thermal conductivity of MHE®301 is 400W/m.K and thermal resistance is 0.100~0.638k/w.
For ENIPIG: Ni≥3µm, Pd≥0.01µm, Au≥0.025µm;
According to different material, the reflectivity can up to 95%-98%.
MHE®601 does not fail after going through 1,000 hours test when temperature is 85℃ and humidity is 85%.
MHE®601 has already passed UL-authorized. For more details, please refer to Rayben UL list.
The voltage resistance of MHE®901 can up to 15KVDC/mm.
Rayben can promise that the peeling strength is ≥ 1.05N/mm.
Depending on the substrate material (copper or aluminum) and additional copper thickness (1Oz, 2Oz & 3Oz), the thermal conductivity ranges from 2.0W/(m.K) to 2.7W/(m.K)
To enter different applications, Rayben is also developing a high-performance double-layer single-sided MCPCB that is ideal for high-power PSUs, projectors and other high-power applications.
To ensure the excellent performance of the 3D MCPCB produced, Rayben uses world-class bendable metal-based.
Comparing with ED copper foil, RA copper foil has better bending capacity.
RAYBEN is capable of a minimum bending angle of 90°.
The minimum outer bending radius and inner bending radius that can be achieved by Rayben is 1.0mm.
The normal voltage resistance is 2.000VDC.
