Programming SMD Microcontrollers Without Soldering

Summary of Programming SMD Microcontrollers Without Soldering


The article discusses an attempt to program an Arduino SMD ATmega328P microcontroller chip wirelessly without soldering by pressing it onto PCB copper pads, inspired by SIM card slot mechanisms. The author designed a custom PCB with an SD card slot layout, a crystal oscillator for clock stability, and pin headers for programming, powered via USB. Although initial tests with the chip soldered worked well, the wireless programming concept remains unproven. The project aims to allow programming of chips without permanent soldering, facilitating sales of pre-programmed ICs.

Parts used in the Wireless Programming Arduino SMD Chip Project:

  • ATmega328P SMD Microcontroller
  • Custom-designed PCB with SD card slot footprint
  • Crystal Oscillator
  • Pin Headers for programming interface
  • USB connector for power supply
  • Power LED indicator

I failed in this wirelessly programming method, But I want to try more methods because finally, we are engineers.

Program SMD Microcontrollers Without Soldering

Story

Working On idea
The PCB has power led which is obviously indication of power and the LED will stop glowing if any short circuit happen in the circuit. The programming system is directly attached to my personal laptop, And I am in Risk of burning my laptop usb hub. So please try this at your own responsibility, if you really want to design something alike.
