SMT vs Through-Hole: Which Assembly Technology Do You Need?
Answer 5 quick questions about your design and application — we’ll recommend the right assembly technology for your layout and explain why. Takes under 60 seconds.
STEP 1 OF 5 20%
What is your smallest component package size?
A.Fine pitch — 0201 imperial, BGA, QFN sub-0.5mm pitch
B.Standard SMT — 0402/0603 imperial, SOIC, TQFP, 0.5–0.8mm QFN
C.Mixed — some fine-pitch SMT plus through-hole connectors, transformers, or large caps
D.Through-hole only — connectors, DIP ICs, radial/axial leaded components

What environment will the PCB operate in?
A.Controlled indoor — office equipment, consumer electronics, standard IoT
B.Light vibration or thermal variation — industrial sensors, HVAC controllers, automotive accessories
C.Harsh — high vibration, wide thermal range, outdoor, military/aerospace prototyping
D.Medical or safety-critical — IPC-A-610 Class 3, full traceability required

What is your target order quantity?
A.5–25 boards (prototype / NPI validation)
B.26–100 boards (small pilot run)
C.101–500 boards (low-volume production)
D.500+ boards (consider full production contract)

Does your design include mechanical or high-current components?
A.No — all ICs, passives, and small connectors (fully SMT compatible)
B.Some — a few board-mount connectors or large electrolytic caps alongside SMT
C.Many — power connectors, large inductors, heat sinks, terminal blocks, relays
D.Primarily mechanical — mostly through-hole for structural or current-handling reasons

What is your highest priority for this order?
A.Lowest cost per board
B.Smallest board footprint / highest component density
C.Maximum mechanical reliability under stress
D.Fastest assembly turnaround
