The electric heating core combines silicon conductive thermal film with special ceramics, which has excellent comprehensive performance and is used to replace traditional electric heating wires.
Products are of good quality and some are of poor quality. Let’s talk about the advantages of good products.
First: the firmness of the solder joints, the problem of the heating core electrode falling off is often encountered during installation. A better quality can accept a much larger pull.
Second: The resistance value of the heating core. The quality of electric heating core imported from Japan is better than that of domestic ones. He added platinum element to it, so that the resistance stability of his temperature sensing wire is high. Now the domestic electric heating core dare to ask that the resistance to high temperature and low temperature changes is not very stable.
Third: High temperature control capability, for example, if the soldering station temperature is set to 480℃, if the soldering station keeps heating up, the problem will be serious if it cannot reach 480℃. The main situation is not that the soldering station heats less than 480℃, but the temperature reaches or even exceeds 480℃, but the signal from the heating core to the soldering station is still not enough. This continuous high current causes damage to the transformer, which will damage the transformer. If you use poor quality, the gain is not worth the loss.
