Device Malcom RCX-1 It is a modular reflow soldering oven inspection and monitoring system (Reflow Checker). 

Main functions

• Check the temperature of the soldering iron.The core component of the RCX-1 is the RCM-S temperature logger with 6 channels, used to measure temperature in reflow soldering ovens or other types of furnaces. It helps to establish a standard temperature profile for each specific product.
• Analysis and control of welding furnacesThis system provides various tools for evaluating performance and troubleshooting issues during the reflow soldering process. 

Scalability

The RCX-1 system's strength lies in its modular design, allowing users to expand its capabilities by adding auxiliary sensors to monitor various factors within the welding furnace: 

• RCX-C (Observation Monitor)Allows for video recording and direct observation of the PCB reflow process inside the oven.
• RCX-O (O₂ Concentration Monitor)Measuring oxygen levels in the furnace helps maintain an optimal welding environment and prevent oxidation.
• RCX-V (Vibration Monitor)Measure the vibration of the conveyor belt or rail during the reflow welding process.
• RCX-W (Air Velocity Monitor)Measuring the wind speed inside the furnace has a significant impact on the heat transfer process during welding.
• RCX-T (Reflow Checker Memory Unit): Expanded temperature measurement capabilities to 12 channels, suitable for more complex applications. 

Benefit

• Ensure the reflow soldering process is tightly controlled to optimize product quality.
• Troubleshooting and adjusting the soldering furnace parameters for optimal efficiency is easy.

To use the modular reflow checker system, you will follow a process involving preparation, setup, and data analysis. This system allows for the measurement of various parameters within the reflow oven, not just temperature. 

Here are the general steps for use:

1. Assemble and install the system.

• Select the necessary modules: Depending on the testing requirements, you will need different modules. For example:
  • Temperature Module (RCM-S): This is the basic module, also known as the "brain" of the system, used to record temperature.
  • Reactive Oxygen Concentration Module (RCM-O): Used to measure oxygen concentration in welding furnaces, often requiring an additional heat-resistant casing.
  • Other modules: Depending on the manufacturer, there may be modules for measuring air velocity, conveyor belt vibration, or even cameras.
• Assemble the equipment: Connect the necessary modules to the main module (e.g., RCM-S). Ensure all connections are secure.
• Connect the thermoelectric probe: Connect the thermocouples to the corresponding channels on the temperature module. 

2. Prepare the circuit board and probes.

• Attach the thermoelectric probes: Solder or attach the thermistor probes to critical locations on the test board. This should be done on a board that is empty or has components similar to those on a production board.
  • Hottest spot: It's usually a lightweight component located near a corner or edge of the circuit board.
  • Coldest location: Typically, it's a large, bulky component (e.g., QFP, BGA) located near the center of the circuit board.
  • Sensitive area: Install additional probes at temperature-sensitive components to ensure they don't overheat.
• Check the wires: Ensure that the wires from the probe are not broken or damaged. Some systems have LED error indicators to warn if a wire is broken before taking a measurement. 

3. Setup and operation

• Connect to your computer: Use a USB cable or other interface to connect the Reflow Checker system to a computer running the control software.
• Software configuration:
  • Open the software and set up the initial parameters such as the type of module being used, the connection port, and the number of transducer channels.
  • If needed, use the help function to easily create a new temperature profile.
• Measurement:
  • Place the circuit board with the probe attached onto the soldering iron conveyor belt.
  • Run this circuit board through the soldering iron. The system will automatically record the data as it passes through.
  • For advanced modules, data on oxygen concentration and other parameters will also be recorded simultaneously. 

4. Data analysis and reporting

• Download data: After the process is complete, download the data from Reflow Checker to your computer. Some devices may store a lot of data even when powered off.
• Analysis using software:
  • The software will display temperature curves, slope analysis, and other parameters.
  • The alerts will be displayed in different colors on the screen for easy identification.
  • You can view temperature, air velocity, and oxygen concentration data simultaneously on the same screen.
• Determine the standard configuration: If the testing process is satisfactory, you can set this configuration as a "golden process profile" for comparison with subsequent tests.
• Generate report: Convert the measurement data to CSV format to create a detailed report. 

5. Monitoring and adjustment

• Set the error limit: Set error limits for the temperature curve and other parameters. This helps determine when the welding process deviates from the standard.
• Regular monitoring: Regularly run Reflow Checker to inspect and monitor the soldering furnace, ensuring that the soldering process remains stable and consistent, especially when changing products or settings.
• Adjust: Based on the analysis results, you can adjust the welding furnace parameters to optimize weld quality and prevent potential problems.
