At RAPID CIRCUIT, we provide precision-engineered double sided PCBs designed for OEMs, industrial applications, and high-performance electronics, ensuring consistent quality from prototype to mass production.
What is a Double Layer PCB?
A double layer PCB, also known as a double sided PCB, has conductive copper layers on both sides of the substrate. These layers are connected through plated through holes (vias), enabling more complex circuit designs compared to single layer boards.
This structure allows better component density and improved electrical performance.

PCB Design & Gerber File Preparation
The 2-layer PCB manufacturing process starts with PCB layout design and Gerber file generation for accurate multilayer circuit fabrication.
Double-Sided Copper Clad Laminate Cutting
Double-sided copper clad laminate materials such as FR4, High TG FR4, Rogers, and CEM materials are cut into required production panel sizes.
PCB CNC Drilling
High-precision CNC drilling machines create component holes, via holes, mounting holes, and slot openings according to PCB design data.
Hole Deburring & Surface Cleaning
PCB panels are cleaned and deburred to remove dust, oxidation, resin residue, and drilling burrs before further processing.
PTH Metallization Process
Plated Through Hole (PTH) processing deposits conductive copper inside drilled holes to establish electrical connections between top and bottom layers.
Dry Film Lamination Process
Photosensitive dry film is laminated onto both PCB copper surfaces under controlled temperature and pressure conditions.
PCB Alignment & UV Exposure
PCB artwork films are aligned accurately, and UV exposure transfers the required circuit pattern onto the photoresist layer.
PCB Developing Process
Chemical developing removes unwanted photoresist material and reveals the PCB copper circuit pattern.
Copper Electroplating Process
Additional copper plating increases copper thickness on traces and plated holes for improved conductivity and reliability.
PCB Copper Etching
Unwanted copper is removed through chemical etching, leaving only the required conductive copper circuitry.
Dry Film Stripping Process
Remaining dry film resist material is removed after the etching process to expose clean copper traces.
Solder Mask Coating Process
Protective solder mask coating is applied on both PCB layers to prevent oxidation, solder bridging, and electrical short circuits.
Silkscreen Printing Process
Component markings, polarity symbols, logos, and PCB identification details are printed on the board surface.
PCB Surface Finishing
Surface finishes such as HASL, Lead-Free HASL, ENIG, Immersion Tin, Immersion Silver, or OSP are applied for solderability and copper protection.
PCB Routing & V-Cut Process
Individual PCBs are separated from production panels using CNC routing or V-cut technology.
PCB Electrical Testing
Electrical testing verifies PCB continuity, open circuits, short circuits, and plated hole connectivity between layers.
Final Quality Inspection
Final inspection checks PCB dimensions, copper alignment, solder mask quality, drilling accuracy, and overall manufacturing standards.
PCB Packaging & Dispatch
Finished 2-layer PCBs are vacuum packed or moisture protected for safe transportation and delivery.
