SMT PCB assembly procedure:
PCB Prep:
Clean the PCB substrate to remove any contaminants that may affect solder joint quality.
Apply solder mask to the PCB to identify copper pads where components will be placed.
A surface treatment such as ENIG (Electroless Nickel Immersion Gold) is applied to the copper pads to promote solderability.
Solder paste print:
Place the stencil over the PCB with the stencil's openings matching the PCB's copper pads.
The solder paste (a mixture of solder alloy particles and flux) is scraped across the stencil, depositing the solder paste on the pads of the PCB.
Precise control of stencil thickness, solder paste volume, and squeegee pressure are critical for consistent solder paste deposition.
Element placement:
Automatic pick-and-place machines use vision systems to accurately identify component locations and place them on the solder paste.
Component orientation, coplanarity, and positional accuracy are critical to reliable solder joints.
Additional components such as connectors or heat sinks can be placed manually.
Reflow soldering
PCB components are passed through a reflow oven with carefully controlled temperature profiles.
The solder paste melts, moistening the component leads and PCB pads, and forms a solder joint as it cools.
Different solder alloys, such as lead-free (such as tin-silver-copper), have specific reflow temperature profiles.
Inspection and Testing:
Visual inspection (manual or automated) checks for proper component placement, solder joint quality, and potential defects.
Automated optical inspection (AOI) systems use machine vision to quickly identify and locate any problems.
Electrical testing, such as in-circuit testing (ICT) or functional testing, verifies the electrical performance of the PCB.
Clean and Conformal Coating (optional):
PCB assemblies may undergo a cleaning process to remove any remaining solder paste or flux.
Conformal coating is a polymeric protective layer that can be applied to PCBs to increase moisture and environmental resistance.
SMT PCB assembly requires strict control over the entire process to ensure high quality and reliability of electronic products. Continuous improvements in automation, process control, and inspection technologies are critical to the widespread use of SMT in modern electronics manufacturing.
