Reflow Soldering and Wave Soldering: Two Primary Methods of Electronic Soldering

1. Reflow Soldering:

   - Reflow soldering is a process where electronic components are placed on a Printed Circuit Board (PCB), which is then conveyed into a heating furnace for soldering. In the heating furnace, solder paste is heated to liquid state and then cooled and solidified, connecting the electronic components to the PCB.

   - This soldering method is suitable for Surface Mount Technology (SMT) and efficiently connects small electronic components.

2. Wave Soldering:

   - Wave soldering involves inserting electronic components into PCB holes already coated with solder paste, and then conveying the entire PCB to a preheating area. After preheating, the PCB passes through a solder wave, where the solder paste is pressed into a wave shape, connecting the electronic components.

   - Wave soldering is suitable for through-hole assembly technology, especially for connecting large electronic components or modules.

Online Oven Temperature Monitoring System: Key Assurance for Soldering Quality

The online oven temperature monitoring system is a crucial system used to monitor and control the furnace temperature during reflow soldering and wave soldering processes. It typically includes the following components:

1. Temperature Sensors:

   - The online oven temperature monitoring system utilizes various types of temperature sensors, such as thermocouples or infrared sensors, to monitor the temperature in the heating furnace in real time.

   - These sensors accurately measure temperature changes during soldering to ensure soldering quality and consistency.

2. Data Acquisition System:

   - It collects data from temperature sensors and transmits it to the control system for analysis and processing.

   - The data acquisition system can monitor temperature changes during soldering in real time and provide timely feedback to adjust the parameters of the heating furnace.

3. Control System:

   - The control system automatically adjusts the parameters of the heating furnace based on information provided by the data acquisition system to ensure temperature control during soldering is within the appropriate range.

   - This helps to avoid temperature deviations during soldering, ensuring soldering quality and consistency.
