Double sided copper circuit board is widely used in aerospace, military, mobile communication, laptop, computer peripherals, PDA, digital cameras and other fields or products.
Bare copper itself has good weldability, but it is easy to be oxidized. In order to ensure good weldability and electrical properties, we need to do various surface treatment processes.
Practical surface treatment processes of Double sided copper circuit board are varied and can be divided into OSP, tin spraying (with lead and without lead), tin sinking, gold sinking, silver sinking, nickel gold sinking, nickel palladium gold sinking, electrohard gold plating, full plate gold plating, gold finger, etc.
(1) It can be bent, wound and folded , which also can be arranged arbitrarily according to spatial layout requirements, and can be moved and expanded arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection.
(2) Double sided copper circuit board can greatly reduce the size and weight of electronic products, suitable for electronic products to high density, miniaturization, high reliable direction of development needs.
(3) Double sided copper circuit board also has the advantages of good heat dissipation and weldability, easy installation and connection, low comprehensive cost, etc. The design of soft and hard combination also makes up for the slight deficiency of the flexible substrate in the bearing capacity of components to a certain extent.
