Reflow soldering system
The two key purposes for soldering: 1. Electrical and power conduction 2. Durable solid mechanical connection strength
The temperature of the solder joints must be up to about 15 °C above the melting point of solder, and maintains a certain amount of time. At this time of the solder joints can send chemical reaction, and in between welding plate and components pins to form a kind of new chemical substances, which is known as the intermetallic compounds, persistently makes strong connection.

The foundation of excellent heat transfer in the reflow is our in-depth understanding of convective heat generation ,transfer and management. Our heater generate the desired temperature faster than any other reflow heat source and respond in less than half a second to temperature change of less than 0.1°C thus maintaining the highest level of temperature repeatability. The heater modules in the oven are also unique in heating air on the intake, allowing it to be blended into a uniformly mixed air blanket.
