Description
🔥 Introduction & Key Features of PVA DeltaTherm
• DeltaTherm is not a coating/dispensing robot like the Delta 6 or Delta 8. It is an infrared heat-curing chamber, designed to dry, bake, and cure adhesives, coatings, potting materials, and other fluids after they have been dispensed or sprayed.
• The PVA DeltaTherm delivers fast, uniform infrared curing for coatings, adhesives, underfill, and potting with precise temperature control and inline conveyor integration
• The system uses infrared heating panels to deliver controlled thermal energy, ensuring proper curing of adhesives, coatings, underfill, potting compounds, conformal coatings, and more.
• DeltaTherm offers a double-sided heating configuration, meaning it can heat from both the top and bottom, ensuring even thermal distribution and reducing curing defects caused by uneven heat.
• The IR panels feature a special protective coating, making them durable and easy to clean, which simplifies maintenance and prolongs equipment life.

✅ Main Advantages of DeltaTherm
• Fast and uniform curing: Infrared heating with dual-sided configuration ensures even thermal distribution, helping adhesives and coatings cure uniformly without defects.
• Optimized for high-volume production: Integrated conveyor makes DeltaTherm ideal for SMT, coating, or potting lines requiring continuous and stable throughput.
• Highly flexible: Supports a wide range of board and pallet sizes (50–500 mm), fitting many industrial and electronic assemblies.
• Compatible with multiple materials: Suitable for adhesives, epoxies, silicones, coating materials, potting compounds, and other heat-curing chemistries up to 260 °C.
• Easy maintenance: IR panels are protected with a durable coating, making cleaning simple and extending operational lifespan.
• Strong process control: PLC + SMEMA connectivity, precise temperature regulation, and independent thermal protection ensure industrial-grade reliability.
🔧 Common Applications
DeltaTherm is typically installed after coating, dispensing, or potting steps to provide heat curing. Common usage includes:
• Curing conformal coatings on PCBs and electronic modules for moisture, dust, and environmental protection
• Curing potting and encapsulation materials like epoxy or silicone for shock, vibration, and moisture resistance
• Curing underfill, gasket material, sealants, and adhesives requiring controlled thermal curing
• Curing thermal interface materials (TIM) that need heat to bond
• High-volume electronics manufacturing, where conveyorized curing ensures consistent quality and efficiency
DeltaTherm often works as the final quality-ensuring stage after coating or dispensing robots like PVA Delta 6 or Delta 8.
📌 When DeltaTherm Is Recommended
Use DeltaTherm when:
• Your coating/dispensing/potting materials require thermal curing.
• You run a high-volume or continuous SMT/coating line needing stable throughput.
• You need precise thermal control to ensure product reliability.
• You want to reduce coating or adhesive defects and improve consistency.
📌 When DeltaTherm May Not Be Ideal
Avoid or reconsider if:
• You only produce small batches and don’t need industrial-level curing.
• Your materials cure at room temperature and do not require heat.
• You lack space or the ability to integrate the machine into a SMEMA-compatible line.
