Product Description
4 layer pcb board with blind hole impedance control pcb board In the circuit having resistance,Website:http://www.xce-pcb.com, inductance and capacitance, the AC played impediment to is called impedance.Impedance by the resistance, inductance and capacitance composed of three, but it is not a simple sum of the three. Impedance is the European unit. In DC, the current object called a role in obstructing the resistance, all of the material world have resistance, but the resistance value of the difference in size only. Very low resistance material called a good conductor, such as metal or the like; resistance great material called an insulator, such as wood and plastic. There is also a conductor interposed between the two is called a semiconductor, and superconductor is a resistance value close to zero substance. However, in addition to the alternating current field will hinder current resistance outside, capacitance and inductance will impede the flow of current, this effect is called reactance, which means resistance to the current role. Capacitance and inductance reactance and inductance are called anti-anti-capacitance, inductance and capacitance for short. Their unit of measure with the same resistance in ohms, and the size and value of the relationship between the frequency of the alternating current, the higher the frequency the smaller inductive reactance is greater, the lower the frequency the greater the capacitance and inductance smaller. Further anti-capacitance and inductance of the phase angle as well as anti-issues have a relationship on the vector, so will say: Impedance is the resistance and reactance on the vectors and. For a specific circuit impedance is not constant but varies with frequency. In the resistance, inductance and capacitance series circuit, the impedance circuit is generally larger than the resistance. I.e. the impedance is reduced to a minimum. In the parallel circuit inductance and capacitance, impedance increased to a maximum resonance when, on the contrary, and this series circuit. 4 layer Blind Via pcb board, one side of the hole in the board surface, and then through to the interior of the board so far.Blind hole is connected to the inner surface layer and not through imposition vias.It means a blind hole vias connected between the inner surface of the finished plate is not visible. These two types of holes are located in the inner layer circuit board, laminated before use through-hole forming process is completed, the through-hole forming process may also overlap several good lining. What Information customer need to provide for quotation ?1.

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.  Model Number:XCEPCB0022    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,UL 4 layer High Tg pcb board represents: a high heat resistance. Usually high Tg of 130 degrees or more plates, excellent high Tg is generally greater than 170 degrees, moderate Tg greater than about 150 degrees, PCB boards normally Tg≥170 ℃, called high Tg PCB. With the rapid development of the electronics industry, especially in the computer as the representative of electronic products toward high performance, high multi-layered development requires a higher heat resistance as an important guarantee of PCB substrate material. The emergence and development of SMT, CMT, represented by high-density mounting technology, the PCB in a small aperture, fine lines, thin side, increasingly inseparable from the high heat resistant substrate support.Tg of the substrate is increased, PCB thermal resistance, moisture resistance, chemical resistance, stability and other characteristics will improve and improve. TG higher the value, the better the sheet temperature resistance, especially in the lead-free process, the high Tg applications more.  Parameter:oItemData1Layer:1 to 24 layers2Material type:FR-4, CEM-1, CEM-3, High TG, FR4 Halogen Free, Rogers3Board thickness:0.20mm to 3.4mm4Copper thickness:0.5 OZ to 4 OZ5Copper thickness in hole:>25.0 um (>1mil)6Max.
