What kind of double-sided aluminum substrate structure can PCBQuick make for you
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
