Detailed Product Description
Double Layers Metal Core PCB
Double layers MCPCB is consisting of two layers of copper conductor, put them on same side of metal core (usually aluminum, copper or iron alloy). The metal base is on the bottom of whole MCPCB, which is different from double sided MCPCB(the two copper layers were put on the each side of metal core respectively), and you can only populat

Detailed Product Description
Double Layers Metal Core PCB
Double Layers MCPCB Is Consisting Of Two Layers Of Copper Conductor, Put Them On Same Side Of Metal Core (usually Aluminum, Copper Or Iron Alloy). The Metal Base Is On The Bottom Of Whole MCPCB, Which Is Different From Double Sided MCPCB(the Two Copper Layers Were Put On The Each Side Of Metal Core Respectively), And You Can Only Populate SMD On Top Side.
Different With Single Layer MCPCB, 2 Layers MCPCB Requires An Additional Pressing Step To Laminate The Imaged Thermal Conductive Laminate And Metal Core (also Known As Metal Base) Together.
Compared With Normal FR4, This Sturcture Need More Technology And Experience On Laminating Of Two Layers Together With Metal Core.
The Processing Steps Of The MCPCB With The Metal Base Embedded In The PCB Are Comparatively Complex As Hole Plugging Is Required After Primary Drilling On The Metal Base In Order To Isolate It From The Circuitry.
Single Layer Metal Core PCB
A Simple Layer Single Sided MCPCB Consists Of A Metal Base (usually Aluminum, Or Copper Alloy), Dielectric (non-conducting) Layer, Copper Circuit Layer, IC Components And Solder Mask.
The Prepreg Dielectric Provides Excellent Heat Transfer From The Foil And Components To The Base Plate, While Maintaining Excellent Electrical Isolation. The Base Aluminum/copper Plate Gives The Single-sided Substrate Mechanical Integrity, And Distributes And Transfers The Heat To A Heat Sink, Mounting Surface Or Directly To The Ambient Air.
The Single-Layer MCPCB Can Be Used With Surface Mount And Chip & Wire Components, And Provides Much Lower Thermal Resistance Than FR4 PWB. The Metal Core Provides Lower Cost Than Ceramic Substrates, And Allows Much Larger Areas Than Ceramic Substrates.
