In short, each hole on the PCB can be called pan holes. From the role of point of view, intraday holes can be divided into two categories:One is used for electrical connection between the layers; the second is used as a device for fixing or positioning. If from the process technology, these disk holes are generally divided into three categories, namely blind holes (blind via), buried vias (buried via) and through-hole (through via). Blind holes located on the top and bottom surfaces of the printed circuit board, having a certain depth, the line for connecting the surface layer and the inner layer below the line, the depth of the hole is usually no more than a certain ratio (aperture). Buried hole printed circuit board means located in the inner connection hole, it does not extend to the surface of the board. 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. The third is called through-hole, this hole through the entire circuit board can be used to implement the interconnect or installed as locating hole components. Since the through-holes in the process easier to implement, low cost, so most of the printed circuit boards are to use it, rather than the other two plate holes.   Company Service:24 hours quick sample is avaliable here.reply Customer's any enquiry within 3 hours;Blind buried hole ,crossed blind hole can be done24 hours Engineering Gerber files treatment.24 hours English Engineering Questions Confirmation by E-mail.Supply the best project fit for production customized Model Number:XCEPCB0019    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:GreenMolde Number:xcepcb0019Silkscreen:WhiteLayer:8Panel Size:105*125mm/5pcsBoard Thickness:1.0mmPackage Details:Inner:Vacuum-packed     Bubble bag     With Foam Outer:Carton BoxMin Line Space:4MilMin Line Width:4MilMin Hole Size:10MilFinished Surface:ENIGSpecial requirement:BGAcopper 25umProvide Slice reportFinished Copper:1ozDelivery Time：8 DaysBGA stands for Ball Grid Array (PCB ball grid array structure), which is an integrated circuit using an organic carrier board an encapsulation method. It has: ① ② reduce package size function to increase the number of pins increases ③PCB board is dissolved welding self-centered, easy on the tin ④ ⑤ good electrical performance, high reliability, and low overall cost. BGA PCB board has more holes in general, most customers BGA lower through-bore design for the finished hole diameter 8 ~ 12mil, BGA surface at a distance from the hole to fit specifications for 31.5mil for example, is generally not less than 10.5mil. BGA vias required under the plug hole, BGA pads are not allowed on the ink, not drilling on the BGA pads.  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.
