"In the semiconductor industry, the component drying process directly affects chip packaging yield and circuit stability. Traditional drying equipment has issues such as poor temperature uniformity (more than ±5℃), insufficient vacuum degree (prone to residual moisture), and low batch processing efficiency (each batch takes more than 4 hours), causing customers to face the dilemma of 'low yield rate and excessively high energy consumption costs accounting for the total production energy consumption'. To address this pain point, Shanghai Guanding has customized precision drying solutions, covering the two core processes of pre-drying after component cleaning and final drying before packaging, with supporting vacuum drying ovens and tunnel-type drying production lines, achieving the three-in-one goal of 'precision temperature control + efficient batch processing + energy saving and consumption reduction'."

1. Core Equipment Configuration and Technical Parameters

Equipment Type	Quantity	Key Technical Parameters	Application Scenarios
Vacuum Drying Oven	12 units	Temperature Control Range: Room Temperature ~ 250℃ (Accuracy ±1℃); Vacuum Degree: ≤1Pa; Volume: 500L/unit; Heating Method: Infrared Radiation + Hot Air Circulation	Drying of small-batch high-precision components (e.g., chip carriers, ceramic substrates) to avoid high-temperature oxidation
Tunnel Drying Production Line	3 lines	Conveying Speed: 0.5~2m/min (frequency-variable); Drying Section Length: 8m; Temperature Control Zones: 5 independent zones (±1℃ per zone); Exhaust System: Multi-stage Filtration + Waste Heat Recovery	Continuous drying of large-batch standard components (e.g., resistors, capacitors, semiconductor diodes) to match the capacity of the customer’s assembly line

2. Core Technical Advantages of the Solution

• Precise Temperature Control System: Adopts a PLC programmable control system + resistance sensors to real-time monitor the temperature inside the drying chamber, solving the problem of "component deformation caused by local overheating" in traditional equipment.

• High-Efficiency Vacuum System: Equipped with a two-stage rotary vane vacuum pump, which can reduce the vacuum degree in the chamber to below 1Pa within 30 minutes for rapid moisture extraction, improving efficiency compared to atmospheric pressure drying.

• Energy-Saving Design: The tunnel oven shell uses 100mm-thick aluminum silicate insulation cotton, with a heat loss rate ≤5%; at the same time, it is equipped with a waste heat recovery device to recycle exhaust heat into the air intake system, reducing power consumption.

• Intelligent Management: The equipment is connected to the customer’s MES production system, enabling real-time upload of drying parameters (temperature, vacuum degree, duration) and generation of production reports for easy quality traceability.

3. Project Implementation Process

1. Demand Research Phase: Conduct in-depth on-site visits to the customer’s production workshop, analyze core indicators such as component materials (e.g., epoxy resin, ceramics, metals), moisture content before drying, and daily capacity to determine equipment parameters.

2. Solution Design and Confirmation: Issue equipment layout diagrams, process flowcharts, and energy consumption calculation reports, and confirm details with the customer’s technical team.

3. Equipment Production and Commissioning: Complete equipment manufacturing at the Kunshan production base, and conduct a 72-hour no-load test run before delivery to ensure performance meets standards.

4. On-Site Installation and Training: Dispatch engineers to the customer’s workshop for equipment installation, MES system integration, and provide operation and maintenance training for operators.

5. After-Sales Support: Provide on-site inspection during the warranty period, and respond to fault reports within 2 hours to ensure stable equipment operation.
