Product Description

 

High Quailty PCB Board Assembly(SMT/DIP/THT) for Medical Equipment

 

 

What is PCB Board Assembly?


 

 

PCB Board Assembly (PCBA)​​ is the process of mounting and soldering electronic components onto a bare ​​Printed Circuit Board (PCB)​​ to create a functional electronic device. It transforms an empty PCB into a working circuit by attaching components like resistors, capacitors, ICs, and connectors.

 

 

 

♦ ​​Key Stages of PCB Assembly​

1. Solder Paste Application​​

    • A ​​stencil​​ aligns with the PCB, and ​​solder paste​​ (a mix of tiny solder particles and flux) is applied to pads where components will be placed.

​​2. Component Placement​​

    • ​​Surface Mount Technology (SMT)​​: Automated ​​pick-and-place machines​​ accurately position tiny SMD components (e.g., resistors, ICs) onto the solder paste.
    • ​​Through-Hole Technology (THT)​​: Larger components (e.g., connectors, transformers) are manually or automatically inserted into drilled holes.

​​3. Soldering​​

    • ​​Reflow Soldering (for SMT)​​: The PCB passes through a ​​reflow oven​​, melting the solder paste to form strong electrical connections.
    • ​​Wave Soldering (for THT)​​: The board moves over a wave of molten solder to bond through-hole components.

​​4. Inspection & Testing​​

    • ​​Automated Optical Inspection (AOI)​​: Cameras check for missing/misaligned parts or soldering defects.
    • ​​In-Circuit Testing (ICT)​​: Electrical probes verify circuit functionality.
    • ​​Functional Testing​​: The assembled PCB is powered on to ensure it works as designed.

​​5. Conformal Coating (Optional)​​

    • A protective coating (e.g., silicone, acrylic) may be applied to shield against moisture, dust, and corrosion.

 

 

♦ ​​Types of PCBA Services​​

 

Type Description Best For
​Turnkey PCBA​ Full service—supplier handles PCB fabrication, component sourcing, assembly, and testing. Startups, companies wanting hassle-free production.
​Consigned PCBA​ Customer provides components; assembler only does placement/soldering. Cost-sensitive projects with existing parts inventory.
​Partial Turnkey​ Hybrid approach—some parts supplied by customer, others by the assembler. Customized builds with specialty components.
