SMT vs Through-Hole: Which is Better for Your PCB?

Both SMT and through-hole have their place in electronics manufacturing, but most modern commercial products rely on SMT for density, speed, and automated production efficiency.

SMT Advantages

• Higher assembly density
• Better automation and repeatability
• Lower cost for repeated builds

Through-Hole Advantages

• Stronger mechanical anchoring
• Useful for certain high-stress applications

Which Should You Choose?

For most sample, NPI, and small-batch commercial PCBA programs, SMT is the more practical choice. Through-hole is typically added only where design or environment requires it.
