Industrial Control PCB & PCBA Manufacturing: From Prototype to Long-Term Supply
Modern factories, process plants, logistics systems and smart buildings all rely on layers of control electronics: PLCs, motion controllers, IO modules, industrial PCs, drives, sensors and gateways. At the center of these systems are industrial control PCBs and industrial control PCBAs that must operate reliably in electrically noisy, high-temperature, high-vibration environments—often 24/7 for many years.
APTPCB supports automation OEMs, machine builders, system integrators and industrial solution providers with production-ready industrial control PCBs and fully assembled industrial control PCBAs. We cover everything from PLC PCBs, motion control PCBs, IO module PCBs and industrial power PCBs to HMI PCBs, industrial PC motherboards, safety controller PCBs and industrial gateway PCBAs used in factory automation, process control, robotics, energy and building automation.

- AOI (Automated Optical Inspection): Checks component presence, type, polarity, placement and visible solder joints
- X-Ray Inspection (As Needed): Examines hidden joints under BGA, LGA, QFN and power packages
- In-Circuit Test (ICT) / Flying Probe (When Designed In): Verifies electrical connectivity, component values and basic functionality
- Functional Test (FCT): Runs power-up and device-specific test routines according to your test specification
- Final Quality Inspection & Traceability: Confirms labels, revision, quantity and cosmetic quality with lot-level or board-level traceability
This layered PCBA quality & testing approach supports consistent behavior across prototypes, pre-series builds and mass production.
