XWONDER supports through-hole and mixed-process PCBA assembly for electronic products that combine surface-mount components with connectors, relays, transformers, large capacitors, and power components. From prototype validation to batch production, our mixed-process capability ensures reliable assembly quality, mechanical strength, and high-current performance.
Many PCBAs still require through-hole components to achieve stronger mechanical retention or better electrical performance. Proper sequencing, soldering method, thermal exposure, board layout, and inspection planning are essential for mixed SMT and through-hole boards to maintain high assembly quality.
Manual or automatic insertion based on component type and order size.
Support for common through-hole components such as resistors, capacitors, and diodes.
Batch soldering of through-hole components for consistent results.
Localized soldering for complex mixed boards.
Flexible support for odd-form parts, engineering samples, and low-volume projects.
Manual inspection, lead cutting, and solder joint correction when required.
| Application Area | Common PCBA Requirements |
|---|---|
| Power Electronics | Transformers, power connectors, high-current components |
| Automotive Electronics | Durable connectors, relays, mixed SMT and THT designs |
| Industrial Control | Terminal blocks, relays, large capacitors, rugged assemblies |
| Medical Devices | Reliable connectors and mixed-process assembly |
| Temperature Control Systems | Power components, relays, control interfaces |
Mixed-process boards require detailed engineering review. XWONDER evaluates component spacing, soldering feasibility, thermal sensitivity, wave soldering direction, fixture requirements, and inspection methods to reduce risks such as solder bridging, insufficient solder, component tilt, heat damage, and poor consistency.
