With the development of the times, the application of PCB is more and more extensive, It is important to understand the production process of PCB, now is the brief introduction of PCB circuit board production process:

Material - Drilling - dry film process - pressing - Copper - plating - Jack - solder (green / green) - Gold - spray tin - molding - open short test - end - laser drilling

PCB circuit board production A( Cut Lamination)

    a-1 ( Sheets Cutting) this  is  the prparation  phase

    a-2 (Panel)(Shear material to Size) 

PCB circuit board production B. (Drilling)

    b-1 (Inner Layer Drilling )

    b-2 (Outer Layer Drilling ) 

    b-3 (2nd Drilling) 

    b-4 (Laser Drilling )(Laser Ablation )

    b-5 (Blind & Buried Hole Drilling)  very important phase

PCB circuit board production C.( Photo Process(D/F))

    c-1 (Pretreatment) 

    c-2 (Dry Film Lamination)

    c-3 (Exposure)Developing , Etching & Stripping

PCB circuit board production Developing , Etching & Stripping (DES )

PCB circuit board production F. (Horizontal Electrolytic Plating)

PCB circuit board production G. (Plug Hole)

PCB circuit board production H. (Solder Mask)

PCB circuit board production I Gold Plating

PCB circuit board production J. (Hot Air Solder Leveling)

PCB circuit board production K. (Profile)(Form)(Electrical Testing) (Continuity & Insulation Testing)

PCB circuit board production M.(Final Visual Inspection)

This is the necessary phase to make sure all the board are good function before delivery. And test method has two: 1 flying probe test 2 open a test fixture

The JY factory will choose one test method deponds on how many pieces need produce. And every method has it’s advantage.

PCB circuit board production N.(Laser Ablation) this is the last state of all the production. After this laser ablation,  all the process are finished.
