Our PCB Assembly service provides efficient and accurate assembly of electronic components on printed circuit boards. We use FR-4 material, renowned for its reliability and durability in electronic applications.
Choose from various surface finishes including HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), and OSP (Organic Solderability Preservatives) to enhance performance and longevity.
For custom PCB assembly quotations, simply provide your BOM (Bill of Materials) list and specifications. Our expert team will review your requirements and deliver a customized solution.
| Feature | Description |
|---|---|
| Electrical Interconnection | Provides the network of traces and vias for proper signal and power flow between components. |
| Miniaturization / High Density | Allows complex circuits to be built in small spaces, primarily through SMT (Surface Mount Technology). |
| Reliability and Consistency | Offers stable physical support, effective thermal management, and highly repeatable electrical performance across all manufactured units. |
| Manufacturability | Enables cost-effective mass production through automated assembly processes (pick-and-place). |
| Design Flexibility | Allows circuit layout to be fully customized for specific performance needs, such as high-speed data or high power. |
- 1. Solder Paste Stenciling: Solder paste is accurately applied to PCB pads through a precision steel stencil, ensuring solder only covers required areas.
- 2. Component Placement: A pick-and-place robot automatically mounts surface-mount devices (SMDs) onto the solder-pasted pads as designed.
- 3. Reflow Soldering: The board goes through a reflow oven where heat melts the solder paste; cooling forms firm, permanent electrical and mechanical connections.
- 4. Inspection & Quality Control: AOI checks component placement, polarity and solder joints. X-ray inspection is used for hidden joints such as BGAs.
- 5. Through-Hole Assembly: Larger or high-power through-hole components are inserted and soldered via wave or selective soldering.
- 6. Final Test & Cleaning: Functional testing verifies performance. The board is cleaned to remove flux residues.
