In the production of PCB multi-layer boards, the curing process is a core procedure that determines the interlayer bonding strength, insulation performance, and dimensional stability of the substrate. Domestic PCB manufacturers face three key pain points: first, the poor temperature control accuracy of traditional curing equipment (±3℃), which leads to blistering and delamination of multi-layer boards after lamination and curing, with a yield rate of only 86%; second, the long curing cycle (8 hours per batch), resulting in a daily production capacity of less than 3,000 square meters for a single production line, which cannot meet the delivery requirements of downstream 5G communication equipment orders; third, the high energy consumption of the equipment (180,000 kWh of electricity consumption per month), with energy costs accounting for 22% of the total production cost, putting significant pressure on enterprises to reduce costs. To address these issues, Shanghai Guanding has customized a PCB material curing solution, covering two core processes: lamination and curing of multi-layer board prepregs (PP sheets) and solder mask ink curing, accompanied by exclusive curing equipment and an intelligent management and control system.

2. Core Technical Advantages of the Solution

• Precise Temperature Control & Pressure Coordination: The lamination & curing machine adopts a PLC programmable control system + PT1000 platinum resistance sensor to adjust temperature and pressure synchronously in real time. It solves the problem of "interlayer bubbles caused by temperature fluctuations" in traditional equipment, increasing curing uniformity to 98%.

• High-Efficiency Curing Design: The lamination & curing machine is equipped with a rapid heating module (heating rate of 10℃/min), reducing the single-batch curing time from 8 hours to 4.5 hours; the oven adopts multi-stage hot air circulation, increasing the curing efficiency of solder mask ink by 60% and avoiding incomplete local curing.

• Energy-Saving & Consumption-Reduction Innovation: The shell of the lamination & curing machine uses 150mm-thick high-density insulation cotton, with a heat loss rate ≤3%; the oven is equipped with a waste heat recovery device to recycle exhaust heat into the air intake system, reducing power consumption; the intelligent system can automatically adjust the equipment’s operating power (e.g., reducing power by 30% during low-load nighttime operation).

• Full-Process Data Traceability: Through integration with the MES system, it collects real-time curing parameters (temperature curve, pressure value, curing duration) of each PCB, automatically generates quality reports, and facilitates the customer to trace the curing process of each batch of products, complying with ISO 9001 quality management requirements.

3. Project Implementation Process

1. Demand Research Phase: Conduct in-depth on-site visits to the customer’s production workshop, analyze PCB product types (multi-layer communication boards, automotive control boards), board thickness (0.8-3.0mm), and monthly production capacity requirements. Test the product yield and energy consumption data of traditional equipment after curing to clarify optimization goals.

2. Solution Design & Confirmation: Issue equipment layout diagrams (matching the customer’s existing workshop workflow), curing process parameter tables (e.g., 180℃ curing temperature, 3MPa pressure, 4.5-hour duration for multi-layer boards), and energy consumption calculation reports, and confirm details with the customer’s technical team.

3. Equipment Production & Commissioning: Complete equipment manufacturing at the Kunshan production base. Conduct a 72-hour no-load test run for the lamination & curing machine (to test temperature control accuracy and pressure stability) and a curing effect test for the oven (to verify ink adhesion).

4. On-Site Installation & Training: Dispatch an engineer team to the customer’s workshop for equipment installation and complete the docking and commissioning with the MES system. Provide training for the customer’s operators and technicians (equipment operation, parameter setting, troubleshooting), and only allow them to work after passing the assessment.

5. After-Sales Support (Free Warranty + Lifetime Maintenance): Provide on-site inspection during the warranty period and respond to equipment failures for maintenance within 2 hours. Offer equipment maintenance training (e.g., heating tube replacement, sensor calibration) to reduce the customer’s later operation and maintenance costs.
