MCPCB с ультра белый припой маска 110 долларов США / Сква

Our MCPCB are with high qualityand competitive price: Base Material:Aluminum base material, 100% Quality Guaranteed. Insulating Materials:Imported high thermal conductive material. Surface Finishing: lead free HAL Features: thermal-conductive material with above 2.0 (W/m·K), up to 8(W/m·K). Adopt Taiwan-made ultra white ink which posses the features of thermalshock-resistant and anti-yellow, in particular for high-class LED lightening products. We are manufacturer of PCB in China, we have made kinds of PCB for our customers. Our engineer have studied a new technology to make the LED PCB, which are low cost but with good quality. You can inform us the requirements of the LED PCB you are needing, we can make the LED PCB for you. Or you can send us the sample, we can make out the PCB the same as yours.
