📂 Folder Structure

• horno_no_modificado/: Contains the original, unmodified schematic files for the oven.
• horno_reflujo/: The main KiCad project for the custom reflow oven hardware. This includes:
  • schematics (.kicad_sch)
  • PCB layout (.kicad_pcb)
  • Bill of Materials (BOM)
  • Production files for manufacturing.
• imagenes/: Reference images and diagrams.

🚀 Getting Started

To work with the hardware files, you will need:

• KiCad: To open and edit the schematic and PCB layout files.

Each subdirectory contains a more detailed README.md file with specific instructions on how to use its contents.

📝 PCB Design Notes & Improvements

While the current electronics are functional, several improvements have been identified for future revisions of the PCB:

• Component Sizing: Migrate all through-hole (THT) components to surface-mount (SMD) to reduce board size.
• Simplify Temperature Sensing: The current design uses four thermocouples, but one is sufficient. Reducing to a single thermocouple will simplify the circuit and free up microcontroller pins.
• Isolate Mounting Holes: The mounting holes are currently connected to the ground plane, which is not ideal. They should be isolated to prevent potential short circuits.
• Upgrade Connectors: The external connectors are undersized for the required current. They should be replaced with larger terminals.

🏠 Enclosure Design Notes & Improvements

The 3D model for the enclosure was designed in Autodesk Inventor. The following improvements have been identified:

• Reduce Size: By optimizing the PCB, the enclosure can be made smaller.
• Improve Closure Mechanism: The current screw-based closure can be replaced with a more practical solution like snap-fit tabs.
• Add Accessibility: Add openings for ventilation and easier access to connectors.
