what is double side printed circuit board ?the FR4 material has 2 copper trace, and also named as "Double Sided PCB" (D/S PCB), and PTH (Via) is a must, but it still doesn't has Buried or Blind hole. Components can be assembled on both top and bottom side, so you don't need to worry about where to put components on the board, and not need to use through hole components which is always expensive than SMD one.Currently this is one of the most popular type of PCB on the world.PCB board SpecificationsPcb thickness:1.6mmLayer account:2-LSurface finished:ENIG,Immersion goldLine width&space4/4milsFinished copper:1ozSolder mask:green;Material:FR4.Certificates:CQC,ISO.TS16949,SGS,ISO9001,UL,ISO.14001,ROHSDelivery time:sample 3-5days,mass production:8-10days;Package details:vacuum pcb,inside bubble all inside,cartoon,ties outside strengthening;double layer pcb boards structureTop silkscreen/LegendTop silkscreen/LegendTop Surface finishingTop Soldermask (overlay)Top TraceSubstrate/Core materialBottom traceBottom soldermask (overlay)Bottom surface finishingBottom silkscreen/legendautomotive industry requirements for pcb is difference from others electronics industry,automotive require high reliability,long life service,high quality with never any others modificationThe sector consists of passenger vehicles, trucks, trailers, sub assemblies, and dealer support systems.KDPCB manufacturer provides the automotive industry printed circuit boards with a wide range of materials, composites, and construction, that perform well in the rigors of the automotive world.kdpcb also fabricate display PCBs, circuits for engines and various electronic components.High Temperature laminates, copper and aluminum substrates perform very well in harsh automotive applications.since 2010,kdpcb has started cooperate with some china local automotive corparation,such as geely automobile company,even Suzuki changan.kdpcb automotive printed circuit board was passed ISO.TS16949,and this is audited by third party company.KDPCB Advantages1--never set any moq for every pcb board order;2--shortest response for all clients need;3--reasonable competitive price with high quality;4--support "one-stop"service for part of clients;5--shortest delivery time on pcb board production;6--"5S"and ISO.TS16949 quality system control manufacture;7--professional,high communication,trustworthy;8--all kinds of pcb board manufacture are acceptable;9--TNT/UPS/DHL/FEDEX/special shipping agency support with lower price;application fieldautomobile electronics,such as control electronics,car vedio electronics,car lighting,instruments electronics;GPS electronics;On board radar,Engine timing systems,Interior LED lighting systems,Electronic mirror controls,Stereo and audio components,Antilock brake systems,ECL/ECU control modules,DC/AC powerconverters,Transmission sensors,Power relays,Digital displays,and others customer-made electronics devices.
