28 Pin DIP IC Base / Socket

Wiring Connections:

• Pin Layout: Each of the 28 pins on the socket corresponds to a pin on the IC, allowing for a direct connection between the IC and the circuit board.
• Through-Hole Mounting: The pins are designed for through-hole soldering on a PCB. Solder each pin into the corresponding hole on the circuit board to create a secure electrical connection.

Power:

• No Power Required: The IC socket itself does not require power. It is purely a physical and electrical connector for the ICs placed within it.

Input and Output:

• Input: The socket receives the 28-pin DIP IC, connecting its pins to the circuit board.
• Output: The pins on the socket create a direct electrical path between the IC and the circuit, ensuring that the IC’s functionality is integrated with the board.

Physical Characteristics:

• Dimensions: Standard size for a 28-pin DIP socket, measuring around 35mm to 37mm in length and 7.5mm to 10mm in width.
• Pin Material: Metal alloy, often tin or gold-plated for corrosion resistance and enhanced conductivity.
• Body Material: Made from durable thermoplastic or high-temperature resistant plastic.
• Color: black for the body, with metallic silver or gold-plated pins.

Technical Specifications:

• Pin Spacing: 2.54mm (0.1 inch), compatible with standard DIP packages.
• Mounting Type: Through-hole, meaning the pins go through the circuit board and are soldered on the opposite side.
• Pin Dimensions: Approximately 0.5mm in diameter, designed to fit standard PCB holes for DIP components.
• Pin Count: 28 pins arranged in two parallel rows.

Additional Features:

• Secure Fit: The IC base/socket holds the IC securely, ensuring a stable connection with the circuit board.
• Compatibility: Compatible with a wide variety of 28-pin ICs, including microcontrollers like the ATmega328P, EEPROM chips, and more.
• Prevents Re-Soldering: Using a socket means the IC can be replaced without having to desolder and resolder components, saving time and reducing wear on the circuit board.

How to Use:

1. Preparation:
   • Ensure that your PCB has a layout compatible with a 28-pin DIP package with 2.54mm spacing between pins.
2. Insert the Socket:
   • Place the IC socket onto the PCB, aligning the pins with the corresponding holes.
   • Ensure the socket’s notch or marker aligns with the orientation marking on your PCB to ensure correct IC placement later.
3. Soldering:
   • Solder each of the 28 pins to the corresponding pads on the PCB. Ensure a solid connection without any short circuits.
4. Insert the IC:
   • Once the socket is securely soldered, gently insert the 28-pin IC into the socket.
   • Press down firmly to ensure the IC is seated properly and all pins are making contact with the socket’s contacts.
5. IC Removal:
   • To remove the IC, gently use an IC extractor tool or flathead screwdriver to lift it out from the socket, ensuring no damage to the IC or the socket.

Applications:

• Microcontroller Projects: Used to house microcontrollers like the ATmega328P for easy replacement or reprogramming.
• EEPROM or Flash Memory: Common in circuits where memory chips need to be removable or upgradable.
• Prototyping: Ideal for projects where ICs may need to be swapped out during development, testing, or debugging.
• Repair: Useful in repair situations where an IC is suspected to be faulty and needs easy replacement.

The 28 Pin DIP IC Base/Socket is an essential component for anyone working with 28-pin DIP ICs, providing protection and ease of installation. Its standard pitch and through-hole design make it compatible with most PCBs, and its heat-resistant material ensures durability during soldering. This socket makes it easy to replace, upgrade, or debug ICs without desoldering, making it a must-have for prototyping and repair tasks.
