The establishment of temperature control process curve parameters. Eutectic welding methods should be used in high-frequency, high-power circuits or circuits that must meet aerospace-level requirements. Heat loss during welding, thermal stress and humidity, particles, and impact or vibration are the key factors that affect the welding effect. Thermal damage will affect the performance of thin-film devices; excessive humidity may cause adhesion, wear, and adhesion; ineffective thermal components will affect heat conduction. The common problem in eutectic is that the temperature of the Heater Block is lower than the eutectic temperature. In this case, the solder can still melt, but there is not enough temperature to diffuse the gold-plated layer on the back of the chip, and the operator is easy to mistakenly think that the solder melt is eutectic. On the other hand, heating the base for too long will cause damage to the circuit metal. It can be seen that the temperature and time control during eutectic is very important. For the above reasons, the setting of the temperature curve is an important factor for the quality of the eutectic.
