ABOUT METAL CLAD PCBS
MCPCB (Metal Clad Printed Circuit Board) technology was initially designed in the 60's for high power applications. Known also as MPCB (Metal Printed Circuit Boards) or IMS (Insulated Metal Substrate). Since then it has been used widely in the LED industry, where the benefits of reduced junction temperatures have been realised.
The advantage of using metal clad material for PCB production as opposed to more traditional materials such as FR4 and CEM is simply to do with the efficient removal of heat. The dielectric insulating material in metal clad materials is designed to have a much superior thermal conductivity than that of FR4—generally ranging from 1W/m-K to 9W/m-K. Allowing for efficient heat removal.
The material used to fabricate metal clad PCBs is made of 3 parts; The base layer, the dielectric, and the copper foil:
THE COPPER FOIl
This is the top copper layer of the material that will eventually be processed into the electrical conductors as per conventional PCBs. Generally 1oz-4oz but can be greater.
THE DIELECTRIC
This is the key part. This is the substance that both electrically isolates the Aluminium base layer from the copper foil, but also allows for rapid heat transfer between the two. It ensures that the heat generated in the components is dispersed to the heat sink as quickly as possible and determines the materials thermal properties. This is the ingredient of the substrate that sets apart a world class material from the cheaper alternatives on the market.
THE BASE LAYER
In the vast majority of cases the base layer is aluminium, generally 1mm-3.2mm thick (most commonly 1.6mm). Aluminium is a very efficient conductor of heat and as such is perfect for applications involving rapid heat transfer.

FAQ
Q1:What's your Aluminum board Thermal Conductivity?
A: Normally 0.8-3W/m.K. If you have special demands please feel free contact us
Q2:Is my PCB file safe if I send it to you for manufacturing?
A: We respect customer's design authority and will never manufacture PCB for someone else without your permission. NDA is acceptable.
Q3:What is your testing policy and how you control the quality?
A: For sample, usually tested by flying probe; for PCB Volume over 3 square meters, usually tested by fixture, this will be more faster. Due to there's many steps to PCB production, we usually do inspection after every step.
Q4: What's your shipping way ?
A: 1. We have our own forwarder to ship goods by DHL, UPS, FEDEX, TNT,EMS.
2. If you have your own forwarder, we can cooperate with them.
Q5: What is your certificate?
A: ISO9001:2008, ISO14001: 2004, UL, SGS,RoHS report.
Q6: What files should we offer?
A: If only need PCB, please provide Gerber File and manufacturing specifications; If need PCBA,Please provide Gerber File, Manufacturing specification, BOM list and Pick & Place/XY file.
Q7: Can I get a sample?
A: Yes, It's reasonable to get a sample to test our quality at first.
