Feb 20, 2025

Lecture Notes: TCD 1304 Linear CCD and PCB Assembly

Introduction

  • Topic: Discussion on TCD 1304 Linear CCD
  • Objective: Review and assembly of a custom-designed PCB for TCD 1304
  • Sponsor: PCBWay

PCB Unpacking and Design Overview

  • Components: PCB designed for TCD 1304, STM32F401 microcontroller
  • Features:
    • Surface-mounted parts
    • Designed to mount CCD on one side
    • Connects to a microcontroller board
  • Board Appearance:
    • Ordered 5 boards, received 6
    • Matte black color for reduced light reflection
    • Clear silk print for component placement (e.g., pin headers, TCD 1304)
    • Markings for 3.3V, VB (battery power), and USB connection

Assembly Process

  • Initial Steps:
    • Hand-solder surface-mounted parts
    • Use of operational amplifier and voltage reference
    • Four mounting holes for easy installation
  • Soldering Details:
    • Passive components soldered first
    • Active components followed (reference voltage, op-amp)
    • Pins soldered alongside headers and sockets for CCD

Challenges and Observations

  • Soldering Quality:
    • Hand soldering described as "ugly" but functional
    • Smooth board edges appreciated for safety
  • Construction Errors:
    • Realized the need to solder sockets before rails to avoid obstruction

Final Assembly

  • Component Alignment:
    • CCD aligned with USB port
    • Consideration for enclosure design with 3D printing
  • Testing Setup:
    • Software used to capture data from the microcontroller
    • Experiment with blocking light using electrical tape on CCD

Testing and Results

  • Data Output:
    • Inverted signal correction using operational amplifier
    • Proof of concept that PCB and CCD work correctly

Conclusion

  • Project Outcome:
    • Successful assembly and testing of PCB and CCD
    • Open offer to purchase PCBs through PCBWay
  • Recommendations:
    • Use PCBWay for PCB and assembly services
    • Mention of additional services like 3D printing and CNC machining

Final Remarks

  • Encouragement to explore PCBWay's services
  • Positive feedback on PCB quality and support received
  • Invitation to access and support through provided website link

Note: These notes summarize the key points from the discussion on building and testing a custom PCB for the TCD 1304 CCD, emphasizing the design, assembly challenges, and testing results.
