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.
