Industrial Control PCB Assembly
Robust PCBA for PLCs, motor drives, power electronics, and automation hardware. Mixed SMT+THT assembly, conformal coating, and extended operating temperature support.
PCBA Manufacturing for Industrial Control
Industrial control electronics must operate reliably for years — often decades — in harsh factory environments characterized by temperature extremes, vibration, dust, humidity, and electrical noise. Kingdta has extensive experience assembling high-density industrial control boards where both SMT and through-hole components are common and reliability is non-negotiable.
Our mixed SMT+THT assembly capability is particularly valuable for industrial boards, which often combine fine-pitch surface mount ICs and sensors with large through-hole power components, connectors, and relays. We support conformal coating and potting for boards deployed in high-humidity, corrosive, or outdoor environments.
We work with industrial automation companies, machine builders, and control system integrators developing PLCs, servo drives, power supplies, HMI panels, and industrial IoT gateways. Our engineering team provides DFM feedback focused on industrial reliability — thermal management, connector selection, creepage and clearance for high-voltage designs, and EMI shielding.
Quality Requirements We Meet
- Mixed SMT+THT assembly for complex industrial boards
- High-voltage clearance and creepage verification
- Conformal coating and potting for harsh environments
- Extended operating temperature range (-40°C to +85°C)
- EMI shielding assembly and grounding verification
- IPC-A-610 Class 2/3 workmanship standards
- Full component traceability for warranty management
