The 28-Pin DIP IC Socket with 2.54mm pitch mounts 28-pin integrated circuits, enabling solder-free swapping in electronics projects. It protects chips like the ATmega328P or PIC16F73 from soldering heat, fitting standard PCBs and prototyping boards. It’s 7.62mm or 15.24mm row spacing fits various PCBs for Arduino projects and repairs. This socket provides stable, reusable connections for circuit assembly.

Usage

• Connection:
  • Align socket pins with PCB or prototyping board holes (2.54mm pitch).
  • Solder pins to the board, applying heat briefly to avoid plastic damage.
  • Insert 28-pin IC, aligning notch or dot with socket’s marking for correct orientation.
• Testing:
  • Inspect soldered pins for cold joints or bends.
  • Insert IC and power the circuit.
  • Verify functionality with a multimeter for continuity or a test circuit (e.g., LED blink with ATmega328P).
  • Ensure IC seats are firmly without loose contacts.
• Troubleshooting:
  • IC not working: Check IC orientation and pin alignment. Reseat IC or replace bent pins.
  • Poor connection: Inspect solder joints; reflow if needed. Clean contacts with isopropyl alcohol.
  • Socket loose: Confirm pins are fully soldered to the board.
• Caution:
  • Solder carefully to avoid overheating the plastic housing.
  • Handle pins gently to prevent bending; use pliers to straighten if needed.
  • Verify IC pin diameter (0.40–0.56mm) before insertion.
  • Keep away from young children due to the choking hazard.
  • Store in a dry place to prevent pin corrosion.
