7kW 180L Box Type Dryer Industrial Drying Oven Ceramic Fiber Chamber ODM

High Cleanliness Drying Oven for Post-Printing Drying of Electronic Components

Ensuring Flawless Circuit Integrity for Maximum Yield

Core Concept:
A precision-engineered oven designed to provide a particle-free, uniformly heated, and precisely controlled environment for drying electronic components after the printing of thick-film pastes (conductive, resistive, dielectric). Its primary goal is to thoroughly evaporate solvents while preventing dust contamination, pattern drift, or "mud-cracking," thereby laying a perfect foundation for subsequent firing or curing processes.

Primary Applications:

• PCB & Ceramic Substrates: Pre-drying of printed conductive traces, resistors, and dielectric layers.

• Solar Cells: Drying of metallization pastes (e.g., silver contacts).

• Sensors & RF Components: Drying of sensitive functional pastes (e.g., platinum resistor pastes).

• Display Manufacturing: Pre-drying of edge electrodes and sealing frits.

5 Key Advantages & Features:

1. Class 1000 (or better) Cleanroom Environment

   • Feature: Constructed with stainless steel and a sealed design, integrated with HEPA/ULPA filtration to supply clean air and maintain a positive pressure inside the chamber.

   • Benefit: Effectively prevents airborne particles from settling on the sticky, uncured paste, eliminating a root cause of short circuits, open circuits, or performance degradation, directly increasing production yield.

2. Exceptional Temperature Uniformity & Control

   • Feature: Utilizes precise PID control and a balanced horizontal/vertical airflow system to guarantee temperature uniformity as tight as ±2°C or better across the entire workspace.

   • Benefit: Ensures consistent drying results for all components on a rack, preventing under-dried or over-dried areas that can lead to deviations in resistance, poor adhesion, or pattern cracking.

3. Programmable Profiles & Adjustable Airflow

   • Feature: Offers programmable controllers for multi-step ramp/soak/cool recipes and adjustable fan speeds for gentle or aggressive drying.

   • Benefit: Prevents "skin formation" where the surface dries too quickly, trapping solvents underneath. Enables process standardization and repeatability, reducing human error.

4. Efficient Operation & Integrated Safety

   • Feature: Designed with energy-efficient heaters and insulation. Includes comprehensive safety features like over-temperature protection, independent thermal limits, and alarm systems.

   • Benefit: Reduces long-term operating costs and ensures safe, reliable 24/7 operation, protecting both the product and the equipment.

5. Ergonomic Design for Easy Maintenance

   • Feature: Includes corrosion-resistant stainless steel shelves, and smooth, rounded internal corners for easy cleaning. Filters are easily accessible for replacement.

   • Benefit: Allows for visual process monitoring and simplifies operation. The easy-to-clean design is crucial for maintaining long-term high cleanliness standards.
