Union Circuits is a professional Aluminum-based Printed Circuit Board manufacturer located in Shenzhen,Website:http://www.unioncircuits.com, China, Aluminum Printed Circuit Boards contain a thin Layer of Thermally Conductive Dielectric Material that Transfers Heat, this thin layer of thermally conductive but electrically insulating dielectric is laminated between the Aluminum base and copper foil. The copper foil is etched into the desired circuit pattern and the metal base draws heat away from this circuit through the thin dielectric.Key Specification  Layer Count1~4MaterialAluminum-base, 1W/m.K, 2W/m.K ~12W/m.K, Tg170 availableFinished Thickness1.0~3.2mmFinished Outer Cu Thickness1OZ, 2OZ, 3OZFinished Inner Cu Thickness1OZ, 2OZSurface FinishLead-free HASL, Immersion Gold, OSPSoldermaskWhite, BlackSilkscreenBlack, WhitePanel Size30x1500mm(max)Attention: "These are the basic specifications we gonna to need for your Printed Circuit Board fabrication, if you need a quick quote or going to order soon, to save time please kindly provide all the fabrication details to us, of course if there were any other special requirements or details out of this specification, please also comment so we can consider it in our quotation."           --From Union Circuits Engineering dept.Product DetailsMOQ1 PieceProduction Lead Time5~15 Working Days Quick turn, 10~20 Working Days mass productionMin.
