♦ What Is PCB Assembly Service?


​​PCB Assembly Service​​ refers to the process of assembling electronic components onto a printed circuit board (PCB) to create a functional electronic device. It involves several stages, from sourcing components to soldering and testing the final product.




 Key Steps in PCB Assembly:​

​​

PCB Fabrication​​:

    • The bare PCB is manufactured with copper traces, pads, and layers based on the design file (Gerber file).

​​Component Sourcing (Procurement)​​:

    • Components (resistors, ICs, capacitors, etc.) are sourced based on the Bill of Materials (BOM).
    • Can include ​​surface-mount (SMD)​​ and ​​through-hole (THT)​​ components.

​​Solder Paste Application​​:

    • For SMD components, solder paste is applied to PCB pads using a stencil.

​​Pick-and-Place Machine​​:

    • Automated machines place SMD components onto the PCB with high precision.

​​Reflow Soldering​​:

    • The PCB passes through a reflow oven, melting the solder paste to form secure electrical connections.

​​Through-Hole Component Insertion (if needed)​​:

    • THT components are inserted manually or via automated insertion machines.

​​Wave Soldering (for THT)​​:

    • The PCB passes over a wave of molten solder to attach THT components.

​​Inspection & Testing​​:

    • ​​AOI (Automated Optical Inspection)​​ checks for defects.
    • ​​Functional Testing​​ ensures the assembled PCB works as intended.

​​Final Cleaning & Packaging​​:

    • Flux residues are cleaned, and the PCB is prepared for shipment.


Types of PCB Assembly Services:​

    • ​​Turnkey PCB Assembly​​: Full service (PCB fabrication + component sourcing + assembly).
    • ​​Partial (Consignment) Assembly​​: Customer provides components; the assembler handles soldering.
    • ​​Prototype Assembly​​: Low-volume assembly for testing designs.
    • ​​High-Volume Production​​: Mass production for commercial devices.
