Purpose of cutting：Cut the flex pcb material (FCCL/cover film/pure rubber, etc.) into PNL size we need for pcb processing
Purpose of FPC LAMINATOR : Pressing the FPC board together with a certain temperature and pressure through a Bonding sheet to form a FPC layer stack
Purpose of blacking the hole : Through the black hole method, a layer of charged carbon powder is attached to the wall of the hole to realize metallization of the hole wall for subsequent copper plating.
Purpose of FPC Board plating: To make the hole wall plate with a standard copper thickness to achieve electrical signal conduction between layers
Purpose of FPC exposure : To achieve FPC graphic image transfer through dry film/exposure principle
Purpose of FPC etching: Acid etching is used to achieve the removal of FPC pattern of copper layer
Plasma degumming: mixing a certain proportion of gas in a vacuum chamber to achieve a vacuum plasma state to meet the purpose of soft board removal or film surface roughening
Stick covering film : protect the copper surface of the FPC board substrate and increase the folding resistance of the FPC board
The purpose of fast laminating : pressing the film at a high temperature for a short period of time, bonding the cover film to the copper surface of the FPC board substrate to enhance the viscosity of the cover film and the FPC board
The purpose of Browning : to roughen the surface of the copper through chemical syrup to increase the bonding force between the FPC board and the rigid board.
The purpose of pressing or laminating : bonding the FPC boards and the rigid boards together by high temperature and high pressure
Purpose of Core board : through the UV laser to control the deep Core board, and the outer layer control depth to form the opening section, to achieve the opening design
Purpose of Routing opening slot : through mechanical forming, form a closed path with the outer layer to achieve the opening design
Laser depth control: open the cover of the thin cover sheet by UV laser depth control
Mechanical control depth: through the mechanical control depth, the outer cover of the thick cover piece is realized.
