SMT Assembly Process Step
Solder Paste Application
Stencil printing deposits precise amounts of solder paste onto designated PCB contact pads.
01
Component Placement
Automated pick-and-place machines retrieve surface-mount devices (SMDs) and accurately position them onto the solder paste-coated pads.
02
Reflow Soldering:
Boards pass through a controlled thermal oven, melting the solder paste to form permanent electrical and mechanical connections.
03
Automated Optical Inspection (AOI):
Vision systems verify component presence, placement accuracy, polarity, and basic solder joint quality post-reflow.
04
Through-Hole Component Insertion
Remaining non-SMD parts (connectors, large capacitors) are manually or automatically inserted into plated through-holes.
05
Wave Soldering (For Mixed Technology):
Boards with through-hole components pass over a molten solder wave, forming connections on the underside.
06
Conformal Coating (If Required):

Protective chemical layer applied to shield assembled boards from environmental factors (moisture, dust, chemicals).

07
Secondary Reflow (For Double-Sided Assembly):

Process repeats (steps 1-4) for components on the board's opposite side, using higher-temperature solder or adhesive.

08
Advanced Inspection & Testing:

X-ray Inspection (AXI): Examines hidden connections (BGAs, QFNs) for voids, bridging, or alignment defects.

In-Circuit Testing (ICT): Electrical verification of component functionality and circuit performance.

Functional Testing (FCT): Validates the fully assembled board against operational specifications.

09
Cleaning & Final Assembly:
Flux residues removed (if needed); boards undergo final integration (housing, connectors) in a controlled environment.
10
Rework & Repair:
Dedicated stations (BGA rework, SMT IR) correct identified defects for component replacement or solder joint remediation.
