Application Scenarios & Expert Tips

• Power Electronics: High-current boards with large DIPs Suggestion: Use thick copper and wave soldering

• Automotive: Vibration-prone modules Suggestion: Prioritize THT over SMT for connectors

• Medical: High-accuracy sensing devices Suggestion: Manual soldering with IPC-A-610 Class 3

• Industrial: Harsh temperature environments Suggestion: Request lead-free solder with thermal profiling

• Audio: Amplifiers with transformer coils Suggestion: Combine THT for coils + SMT for logic

FAQ

Q1: What is the advantage of THT PCB assembly over SMT?

A: THT offers stronger mechanical bonding, making it ideal for high-stress or high-current applications like transformers or connectors.

Q2: Do you support mixed THT and SMT assemblies?

A: Yes, we specialize in mixed technology PCB assemblies using both SMT and through-hole components.

Q3: Is RoHS-compliant wave soldering available?

A: Yes. We support both lead-free (RoHS) and traditional SnPb wave soldering processes.

Q4: Can you handle large-pin components or heavy-duty connectors?

A: Absolutely. Our skilled manual soldering team is trained for high pin-count and mechanically sensitive parts.

Q5: What files do I need to provide for a THT assembly quote?

A: Please submit Gerber files, BOM, assembly drawings, and XY placement files if available.
