Detailed Description
what's multilayer printed circuit boards ?MultiLayer pcb board means has more than two copper layers, such as 4L, 6L, 8L, 10L, 12L, etc. As technology improving, people can put more and more copper layers on the same board. Currently, kdpcb can produce 2L-24L FR4 pcb.More layers it means more complex & difficult, the manufacturing cost will be more expensive. The lead time of multi-layer PCB is different from normal one, please contact usfor a exact lead time.PCB board SpecificationsPcb thickness:1.6mmLayer account:8-LayerSurface finished:immersion gold;Line width&space3/3milsFinished copper:1ozSolder mask:green;Material:FR4.Certificates:CQC,ISO.TS16949,SGS,ISO9001,UL,ISO.14001,ROHSDelivery time:sample 3-5days,mass production:10-14days;Package details:vacuum pcb,inside bubble all inside,cartoon,ties outside strengthening;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;multilayer printed circuit boards advantageAdvantages: high density, small volume, light quality because of high density, the attachment between the parts (including the components) is reduced, thereby improving reliability;Can increase the wiring layer, thus increases the design flexibility;Can form a certain impedance circuit;Can form high speed transmission circuit;Can be set up circuit, the magnetic shielding layer, still can set metal core cooling layer in order to satisfy special functions such as shielding, heat dissipation;Simple installation, high reliability.Disadvantages: high cost;Cycle is long;Need high reliability testing means.Multilayer printed circuit is to high speed, multi-functional electronic technology, large capacity, small volume product of direction.With the continuous development of electronic technology, especially the mass and the extensive application of very large scale integrated circuit, multilayer printed circuit is fast development to the direction of high density, high precision, high count and t appear fine lines, small aperture through hole, blind hole buried, high thickness ratio of aperture technology to meet the needs of the market.8 layer pcb circuit boards structureTop silkscreen/LegendTop Surface finishingTop Soldermask (overlay)Top TraceSubstrate/Core materialPrereg (PP)Middle Layers(Inner1.2.3.4.5.6)Prepreg (PP)Bottom trace (if any)Bottom soldermask (overlay)Bottom surface finishingBottom silkscreen/legendmultilayer pcb boards is one of kdpcb pcb manufacturer product,with strong engineers teams in kdpcb,and best suppliers support,continually improve manufacture technology and improting auto-mahines for production,now kdpcb has become a famous pcb manufacturer in china ,which only quality oriented ,not price firstly,even though,our multilayer pcb price still quite competitive in china pcb industry.all our material vendors is only the famous brand manufacturers such as KB group/ITEQ/ROGERS and others;With us, you receive unparalleled technical expertise support for 8 layer pcb manufacture or PCBA;we strive for our customers to feel that our service is so unique and valuable that they would want to work with us forever.We understand that 1)you want solutions support not always make trouble to you ,2)you want what you need and not what a boardhouse wants to sell you.application fieldtelecommunication electronics,computer electronics,such as computer SD card;industrial electronics; url:http://www.kd-pcb.com
