A quick check on Element 14 says that this MCU costs RM 19. That is an expensive microcontroller.
Normally a heat gun is required to remove SMD components but I couldn’t be bothered to buy one just to remove a few parts. I’m using the good old soldering iron and armed with a trick I learned from the Internet, that chip is coming out in no time.
The trick is to apply a lot of solder onto the pins. This is to trap heat and prevent the solder from cooling down too fast when I’m going across all of the pins with the soldering iron.
After a few wiggles the IC came free.
I used a solder wick to remove the excess solder.
The PIC18F2550 in all of its’ glory.
Further cleaning of the pins using flux and solder wick. Shiny.
The package of this IC is called SOIC. The pin pitch is 0.05″, half the normal “breadboard” spacing of 0.1″.
I have a SOIC to DIP adapter lying around so I used that to test the IC.
I’m not going to solder the IC on it because I might need to use it on future projects.
Instead I just used some clothes clip to apply pressure onto the IC.
Connected the Pickit programmer.
And it worked! The Pickit program recognized it as PIC18F2550.
Wrote a simple code on MPLAB X to blink an LED.
Salvage process – Success!
