For electronics manufacturers in Brazil’s growing industrial and consumer electronics sector, upgrading from manual coating to automated conformal coating is a critical step — improving coverage consistency, reducing material waste, and meeting the quality requirements of export customers. This case documents the installation of Sanco’s Three-Axis Conformal Coating Machine at an electronics manufacturer in Brazil, forming a complete inline coating and curing solution.
Customer Background
| Item | Details |
|---|---|
| Location | Brazil |
| Industry | Electronics manufacturing — industrial control boards and consumer electronics PCB assembly |
| Equipment Selected | Three-Axis Conformal Coating Machine + UV Curing Oven |
| Goal | Replace manual coating process with automated selective coating; improve coverage consistency and reduce material waste across multiple board types |
Equipment Selected: Three-Axis Conformal Coating Machine
The customer had been running a manual spray coating process that produced inconsistent coverage thickness and required extensive masking labor. After evaluating options, they selected Sanco’s three-axis conformal coating machine for its programmable selective coating capability, multi-valve compatibility, and straightforward software that their team could learn quickly. The equipment was supplied as part of a complete coating line alongside a UV curing oven for inline curing of UV-formulated coating materials.
Key Features of the Three-Axis Coating Machine
Motion & Coating Control System
| Feature | Benefit |
|---|---|
| Three-axis (X/Y/Z) servo-driven motion system | Precise path execution across complex board layouts — consistent results run to run without operator variation |
| Programmable selective coating paths | Define keep-out zones for connectors and sensitive components — eliminates masking tape labor entirely |
| Multiple valve head options (spray, needle, film) | One machine handles acrylic, silicone, polyurethane, and UV-cure coatings — flexible across product lines |
| Adjustable flow rate and coating width | Fine-tune coverage thickness per board specification — reduces material consumption vs. manual spray |
Software & Programming
| Function | Benefit |
|---|---|
| Offline programming via CAD/Gerber import | New board programs created without stopping the machine — zero production interruption during changeover setup |
| Program storage and one-touch recall | Save programs for all board variants — operators switch products in seconds, no re-programming needed |
| Real-time path simulation on screen | Verify coating route before first board runs — prevents coating defects and material waste during setup |
Mechanical & Maintenance Design
| Module | Feature | Benefit |
|---|---|---|
| Conveyor & Board Transport | Adjustable-width conveyor compatible with standard PCB carriers | Handles multiple board sizes without tooling changes — reduces changeover time between product runs |
| Enclosed Coating Chamber | Sealed working area with exhaust extraction port | Solvent vapor contained and vented — meets workshop safety requirements for coating operations |
| Nozzle & Valve Access | Tool-free nozzle removal for cleaning and replacement | Routine maintenance completed quickly without extended downtime |
Curing Oven: Completing the Inline Coating Process
The customer integrated Sanco’s UV curing oven directly after the coating machine, enabling inline curing of their UV-formulated conformal coating. This replaced a separate batch oven step, reducing floor space usage and eliminating the work-in-progress queue between coating and curing. Sanco’s full curing oven range covers the complete spectrum of coating cure requirements:
| Curing Equipment | Main Application | Kenmerken |
|---|---|---|
| UV-uithardende oven | UV conformal coating and UV adhesive curing | Fast cure speed; inline conveyor integration; suitable for high-efficiency production |
| UV LED droogoven | Energy-saving UV curing for heat-sensitive assemblies | Low energy consumption, minimal heat output, long LED service life |
| IR droogoven | Heating and drying of non-UV coating materials | Uniform temperature distribution across board surface |
| Hete wind uithardingsoven | Drying of acrylic and polyurethane conformal coatings | Suitable for continuous inline production with stable temperature control |
