| Message: | Copper substrate pcbCopper base board circuit layer with a lot of current-carrying capacity, thus should use thicker copper foil and the thickness of the general 35 microns to 280 microns;Thermal insulation layer is copper substrate core technology, the core component of thermal conductivity for 3 oxidation 2 aluminium and silicon powder and epoxy resin filled polymer composition, thermal resistance is small (0.15), viscoelastic can good, has the ability of thermal aging, able to withstand mechanical and thermal stress.PCB board SpecificationsPcb thickness:5.0mmLayer account:1-LayerSurface finished:OSPLine width&space8/9milsFinished copper:3ozSolder mask:white;Material:CU copper base material.Certificates:CQC,ISO.TS16949,SGS,ISO9001,UL,ISO.14001,ROHSDelivery time:sample 3-5days,mass production:8-12days;Package details:vacuum pcb,inside bubble all inside,cartoon,ties outside strengthening;copper base pcb usually have a heavy gold copper substrate, silver plated copper substrate, tin copper substrate, copper oxide substrate resistance, etc.metal core pcb boards includes aluminum base circuit board and copper base circuit board,even others steel base pcb board,aluminum core is normal material use in led lighting or others industry electronics,however,copper base pcb board is not the normal pcb among metal core pcb,cause of the material is too expensive.so it also lead to copper base pcb price always higher.however,kdpcb pcb manufacturer has strong network with the best copper base PCB material manufacturers in china, with kdpcb own metal pcb production line and years experience engineers, kdpcb can provide our customers copper core printed circuit boards with high quality, with a great variety of technologies of kdpcb,now we can control the production cost very well for lot of our clients,it means we can supply them with more better price.KDPCB Advantages1--never set any moq for every pcb board order;2--shortest response for all clients need;3--reasonable competitive price with hi......url:http://www.kd-pcb.com |
