Carbon Oil Pcb Board With Counter Sunk Hole For 10 Multilayer Pcb Board

Carbon oil pcb board with counter sunk hole for 10 multilayer pcb board counter sunk hole process involves drilling and sink hole machining. Counterbore is divided into flat and tapered counter bore.Whatever the counter sunk hole,Website:http://www.xce-pcb.com, we need to hold a major drill drilling through-holes, and then select a different cutting tools for hole machining according to Counterbore shape.Flat sink hole drilling process on the basis of need, by the end of the milling cutter sink holes. Cone Penetration hole required a larger drill has been drilled were hollowed out. Shen hole machining, a workpiece positioning guarantee to ensure concentricity hole and sink holes. Indian Oil is the use of carbon-screen printing technology, the position designated PCB board printed carbon oil, carbon film has a qualified resistance is formed after curing oven test OK instead of the original resistive element. Production and printing of characters similar, the difference is only carbon oil has good electrical conductivity, and the character is a semiconductor material, logo and separated only play the role of welding. Model Number:XCEPCB0015    Shipping port:ShenZhen/HongKong          Place of origin:GuangDong,China    Delivery Time:3-10 Working Days  Production capacity:FR4:2000000Sqms   High Frequency board:10000SqmsPrice Terms:FOBMinimum Order Quantity:1pcPayment terms:TT,Paypal,Western UnionCertification:CE,ROHS,FCC,ISO9008,SGS,ULMaterial:FR4Soldermask:BlackMolde Number:xcepcb0015Silkscreen:WhiteLayer:10Panel Size:95*95mmBoard Thickness:1.6mmPackage Details:Inner:Vacuum-packed     Bubble bag     With Foam Outer:Carton BoxMin Line Space:4MilMin Line Width:4MilMin Hole Size:10MilFinished Surface:ENIGSpecial requirement:Carton oilcounter sunk hole.Provide Slice reportFinished Copper:1ozDelivery Time：8 DaysSpecification:FR-4 material is a fire code rating, represents a material specification is meant a resin material through the combustion state must be self-extinguishing, it is not a material name, but a material grade. So now FR-4 grade material is typically used in circuit boards, there are many species, but most are based on the so-called four-function (Tera-Function) plus epoxy filler (Filler) and glass fiber made composite materials. Defined impedance board is: a good laminated structure will be able to play on the printed circuit board characteristic impedance control, the traces can be formed easily controlled and predictable transmission line structure is called impedance plate. Current common characteristic impedance is divided into: single-ended (line) impedance differential (fixed) impedance coplanar impedance.Single-ended (wire) Impedance: English single ended impedance, refers to a single signal line measured impedance.Difference (Fixed) Impedance: English differential impedance, differential drive means to the test in two monospaced equally spaced transmission line impedance.Coplanar impedance: English coplanar impedance, refers to the signal line at around GND / VCC (signal lines to both sides GND / VCC equal spacing) between the test transmission to the impedance.  Competitive Advantage:1) With UL,ROHS,ISO,IPC2).Lead time:3-10 working days3)Competitive price best quality4).Rich 20 years experience in High Tg Multilayer PCB . What Information customer need to provide for quotation ?1.
