2 OZ PCBA Immersion Gold PCB Assembly Electronic Components for Electronical Equipment
Description of PCBA Assembly Printed Circuit Board
PCBA (Printed Circuit Board Assembly) is the process of attaching electronic components to a printed circuit board. Here are the typical steps involved in the PCBA production process:
1. Solder paste printing: Solder paste is applied to the surface of the PCB where components will be mounted using a stencil.
2. Component placement: The machine picks up the components from the reel or tray and accurately places them on the PCB according to the design.
3. Reflow soldering: The PCB is heated in a reflow oven, which melts the solder paste and secures the components to the board.
4. Inspection: After reflow, the board is inspected for defects such as solder bridging, tombstoning, and missing components.
5. Testing: The assembled board is then tested to ensure that it meets the required functionality and performance standards.
6. Cleaning: The board is cleaned to remove any flux residue or other contaminants.
7. Packaging and shipping: The finished board is packed and shipped to the customer.
Note that some additional steps may be required depending on the complexity of the PCB and the specific requirements of the customer.
