SC-903R Questions and Answers
Can the SC-903R support double-sided PCB coating?
Yes, using the optional barcode reader to automatically call side-A and side-B programs.
What does "4-axis" mean in the SC-903R's design?
X/Y path movement, Z height control, and an R axis (±180° rotation) for side and angled coating on tall components .
What PCB sizes and component heights does the SC-903R accommodate?
Stroke: 400 × 450mm; Component height: 70mm. Accuracy is ±0.05mm.
What are the installation and utility requirements for the SC-903R?
Power: AC220V (4.5 kW); Air: 0.4–0.6 MPa; Weight: 1,100 kg; Tank: 10L .
What integration does the SC-930R offer with the SASinno IR Cure Oven?
Conveyor heights (920mm and 900mm) are compatible for direct inline connection.
What is the SC-Series CCD fiducial mark recognition system?
It photographs marks to correct program offset automatically and can read barcodes to call correct programs.
How does the SC-Series glue weighing system prevent coating misses?
It monitors the tank weight and alerts operators before it is empty, preventing expensive defects and rework.
What SC-Series valve types are available, and how do I choose?
Needle (dots), Narrow spray (standard), Wide spray, and Film coating (precision film). Narrow spray and needle valves are standard.
What is SC-Series selective conformal coating, and why does it require a dedicated machine?
It applies protective polymer (acrylic, silicone, etc.) only where needed, leaving connectors clear. It eliminates manual masking labor and reduces material waste.
What is the SC-Series Film Coating Valve V-5000, and when should I specify it?
It applies a non-atomized film (0.05–0.2mm) with no overspray. Specify it when material cost is high or masking must be eliminated.
