The I.C.T SMT PCBA Conformal Coating Spray Machine is designed to provide precise, uniform coating on SMT and DIP PCBs. Multi-axis coating robots with adjustable valves deliver high-quality coverage across varying board layouts and material viscosities. The line includes automated conveyors, IR/UV curing zones, and optional vision monitoring to ensure coating quality and production consistency. With PLC and PC-based control, operators can easily manage speed, spray height, curing temperature, and line flow. This coating line supports high-throughput SMT production while maintaining safety and process accuracy.
The PCBA Coating Line features multi-axis coating robots capable of delivering uniform conformal coatings across complex PCB surfaces. Each robot supports adjustable spray valves to accommodate varying material viscosities, including UV-sensitive adhesives, epoxy, and solvent-based coatings. Automated height detection ensures consistent coating thickness, while edge recognition prevents overflow or under-coverage. This configuration maintains high precision for single- or double-sided coating, reducing material waste and ensuring consistent quality across diverse PCB types and densities.
The line incorporates a flexible conveyor system with stepper motor-driven chains and adjustable width to handle PCBs of different sizes and thicknesses. Automated buffer zones and push mechanisms stabilize boards during coating and curing, preventing misalignment or collisions. The system supports vertical lift tables, optional return mechanisms, and real-time PCB position detection through fiber optic sensors. These features enable high-throughput processing while maintaining precise positioning for each board, critical for consistent coating results in SMT and DIP production lines.
The coating line integrates IR/UV curing ovens with modular zone control and independent cooling areas. Each curing zone is monitored to maintain optimal temperature and exposure for different materials. The PLC-based control system allows operators to adjust conveyor speed, curing intensity, and process parameters in real time. Optional CCD vision systems monitor coating quality, ensuring uniform coverage and detecting defects before the PCB exits the line. This integration of coating, curing, and quality inspection provides a fully automated, high-precision, and repeatable process suitable for large-scale SMT PCB production.
The coating line integrates with I.C.T’s SMT and DIP production solutions. Related equipment includes pick-and-place machines, wave/ selective soldering, jet dispensers, reflow ovens, AOI inspection, and depaneling units. Integration ensures smooth workflow, from component placement to coating, curing, inspection, and final handling. Operators can track coating quality and process metrics in real time. This allows full-line automation with reduced manual intervention, consistent quality, and optimized throughput across SMT, DIP, and coating operations.

In December 2025, I.C.T successfully delivered three production lines—SMT, DIP, and Coating—to a customer in Saudi Arabia. Engineers conducted on-site installation, training, and commissioning for the client’s team. The customer intends to establish a new ODM factory to independently develop, design, and manufacture PCBs. Earlier, in June 2025, the customer visited I.C.T for equipment inspection, strengthening mutual understanding. After smooth delivery and setup, the client awarded I.C.T engineers an honorary certificate, recognizing their professional service and the reliable performance of the delivered lines.
I.C.T provides comprehensive support across the entire SMT, DIP, and coating factory, not limited to individual machines. Pre-delivery planning includes PCB types, coating materials, line speed, factory layout, and future expansion. After delivery, engineers support installation, commissioning, operator training, maintenance guidance, and process optimization. Integration of coating, curing, handling, and inspection equipment is ensured for stable operation. New factories receive guidance from planning to trial production. Existing lines benefit from workflow optimization, balanced operations, and high-quality, repeatable coating results.
Customers highlight I.C.T’s practical guidance and rapid response. Engineers provide clear instructions and training, helping operators reduce errors and improve throughput. Protective packaging ensures safe equipment transport. Technical issues during installation or production are addressed promptly by a coordinated team. Clients gain confidence in operating new SMT, DIP, and coating lines, achieving consistent, high-quality coating and curing across diverse PCBs.
The SMT PCBA Conformal Coating line is CE, ISO9001 certified, and complies with international safety standards. Quality control includes component inspection, assembly verification, functional testing, packing confirmation, shipment tracking, installation records, and post-sale service. These procedures ensure reliable, repeatable coating performance, minimize production risk, and maintain consistent results across high-throughput SMT and DIP PCB operations.
I.C.T delivers end-to-end solutions for SMT, DIP, coating, dispensing, assembly, and smart factory projects. In-house R&D, production, engineering, sales, and service teams support customers from planning to steady operation. The company has implemented projects globally, providing equipment, installation, training, and process optimization. Beyond selling machines, I.C.T helps build new factories from 0 to 1 and upgrade existing facilities from 1 to 10, enabling scalable, precise, and reliable SMT, DIP, and coating PCB production systems.
