Flex PCB Manufacturing Process:

Substrate Preparation: The flexible material, usually polyimide or polyester, is coated with adhesive and cured.
Copper Cladding: A thin layer of copper is applied to the substrate through processes like electroplating or lamination.
Circuit Patterning: The desired circuit pattern is formed by selectively etching away the unwanted copper using photolithography or laser ablation.
Layer Bonding: In the case of multilayer flex PCBs, the individual layers are stacked together and bonded with adhesive.
Drilling and Plating: Holes for component mounting or interconnection are drilled and then plated to provide electrical connectivity between layers.
Surface Finishing: The exposed copper surfaces are coated with finishes like solder mask and protective coatings to protect against oxidation and facilitate soldering.
Component Assembly: Electronic components are mounted onto the flex PCB using surface mount technology (SMT) or through-hole technology (THT).
Testing and Inspection: The assembled flex PCBs undergo various tests and inspections to ensure functionality and quality.

Types of Flex PCBs:

Single-sided Flex PCB: Consists of a single conductive layer.
Double-sided Flex PCB: Contains conductive layers on both sides, interconnected by plated-through holes (PTHs).
Multilayer Flex PCB: Consists of three or more conductive layers with insulating layers in between.
Rigid-Flex PCB: Combines flexible and rigid sections, allowing for the integration of both flexible and rigid board
