At CADDLINE SYSTEMS PVT LTD , we provide end-to-end PCB assembling services — from component sourcing and placement to soldering, inspection, and testing. Our goal is to deliver high-quality, production-ready PCBs that meet your electrical and mechanical design requirements with absolute precision.

Whether you need prototype assemblies for development or full-scale production , we handle every project with attention to detail, consistency, and quality assurance.

Our PCB Assembly Capabilities

Surface Mount Technology (SMT) Assembly

High-speed pick-and-place machines for SMD components (as small as 0402).

Single and double-sided SMT assembly.

Fine-pitch and BGA component handling.

Through-Hole (THT) Assembly

Manual or wave soldering options for through-hole components.

Ideal for power boards and mechanically strong assemblies.

Mixed Technology Assembly

Combined SMT and THT assembly for complex designs.

Perfect for industrial and automotive PCBs.

Prototype & Low-Volume Assembly

Rapid turnaround for prototype development.

Small batch assembly with flexible order quantities.

Full Production Assembly

Scalable production for medium to large-volume runs.

Strict process control to ensure repeatable quality.

Assembly Process Workflow

1.Material Preparation & Verification

BOM (Bill of Materials) review and component validation.

Component sourcing from trusted suppliers or customer-provided kits. 

2.Solder Paste Printing

Automated stencil printing with inspection for uniform solder deposition.

3.Component Placement

Automated placement using high-speed SMT machines.

4.Reflow Soldering / Wave Soldering

Controlled heating profiles for reliable solder joints.

Separate processes for leaded or RoHS-compliant assemblies.

5. Inspection & Quality Control

AOI (Automated Optical Inspection) for every board.

X-ray inspection for BGA and hidden joints.

Functional testing as per client specifications.

6. Final Cleaning & Packaging

Ultrasonic cleaning and anti-static packaging to ensure safe delivery.

Quality Assurance

We follow strict quality standards and inspection protocols at every stage of the process.

Each PCB assembly is checked for:

Component orientation and alignment

Solder joint quality

Electrical continuity and short detection

Functional verification (if applicable)

Supported PCB Types

Single-Sided & Double-Sided Boards

Multilayer PCBs

Rigid, Flexible, and Rigid-Flex PCBs

High-Frequency & High-Density Boards
