Pain point
As one of the key links in the PCB manufacturing process, the pressing process determines the interlayer bonding strength and electrical performance of the circuit board, too high or too low temperature may lead to plate deformation, bubbles, delamination and other defects, and then affect the reliability and stability of the whole machine. The solution is mainly to solve two aspects: first, the temperature uniformity, the need to ensure that the entire pressing area temperature distribution is consistent, to avoid local overheating or undercooling; The second is energy efficiency and cost, how to maximize the use of energy and reduce production costs while ensuring the accuracy of temperature control.
Solution (Select equipment)
In response to the above temperature control problems, AODE introduces two 1200KW electric heating thermal oil boilers and a 2400KW natural gas thermal oil boiler to optimize the temperature control system of the PCB pressing process, which can achieve temperature control from normal temperature to 260℃, with temperature control accuracy of ±1℃. The electric heating thermal oil boiler adopts imported brand accessories, including motors and touch screens. At the same time, it is equipped with reverse phase, oil shortage, overtemperature, overload, heating abnormal protection and pressure protection functions. This combined solution not only solves the problems of temperature uniformity and energy efficiency, but also greatly improves the reliability and flexibility of the system.
The PCB pressure process temperature control system also has the following three advantages:
Dual energy complementarity: The scheme makes full use of the advantages of natural gas and electricity, using natural gas as the main energy source during the day due to its stable supply and relatively low cost; At night, switching to electric heating takes advantage of low electricity prices to further reduce energy costs. This way of selecting energy according to the time period realizes the optimization of energy use.
Mutual backup, no downtime maintenance: the three boiler systems not only work independently, but also back up each other. When one of the boilers needs maintenance or fails, the other boilers can immediately take over the work, ensuring that production is not interrupted. This design greatly reduces downtime due to equipment failures and improves overall productivity.
Efficient temperature control: As a heat carrier, thermal oil has the characteristics of good thermal stability, high thermal efficiency and accurate temperature control. Aude Composite industry solutions ensure temperature uniformity and stability during PCB pressing by precisely controlling the circulating temperature and flow of the heat transfer oil, thereby effectively improving product quality.
Effect
The temperature control solution in this case not only solves the temperature control problem in the PCB pressing process, but also realizes the energy cost saving and production efficiency improvement through the design of dual energy complementary and complementary. This success story provides valuable lessons for PCB manufacturers and promotes the industry's transition to a more efficient and environmentally friendly production model.
