Double-sided Aluminum PCB Process & Structure

The pressing process of the double-side Aluminium PCB substrate is different from the normal FR4 multilayer PCB board production. It is a special technology, the key difference lies in its stack-up structure, PCBQuick factory has two kinds of double-sided aluminium base laminated structure. 


The First :

Aluminum material cutting-----Drilling----Anodic oxidation----Laminated----Drilling---PTH---Pattern Etching

----Printed Soldermask----Surface Finish---O/S Testing----N/C Routing

The Lamination as follows:

------------------L1

------------------PP

------------------Alu

------------------pp

------------------L2

 The Second:


Aluminum material cutting-----Drilling----Anodic oxidation----FR4 Cutting----Drilling---L2 Pattern Etching---Laminated----L1 Pattern Etching----Printed Soldermask----Surface Finish---O/S Testing----N/C Routing
The Lamination as follows:

----------------L1

----------------FR4

----------------L2

----------------PP

----------------Alu
