QFN48 QFN44 to DIP Adapter Board - 0.5mm Double-Sided Converter

Specifications

• Outer Dimensions: 25.4mm x 25.4mm

• Pitch (Both Sides): 0.5mm

• Material: FR-4 Glass Fiber

• DIP Output Pitch: Standard 2.54mm

• Thermal Pad: Integrated center ground/thermal pad on both sides for heat dissipation

• Pin Count: Supports 44-pin and 48-pin configurations

Key Applications & Projects

• Microcontroller Development: Prototype with 48-pin LQFP microcontrollers on a standard breadboard.

• RF & Wireless Testing: Evaluate high-density RF chips in QFN-44 packages.

• Complex Logic Interfacing: Break out high-pin-count SMD logic gates or CPLDs for easy wiring.

Unlock New Capabilities (Project Evolution)

• Feature Upgrade: The integrated central thermal pad is specifically designed for high-performance chips that require a ground or thermal connection to prevent overheating during operation.

• Effort Level: Advanced. Requires high-precision soldering or a hot air rework station due to the leadless nature of QFN and the 0.5mm pitch.

Package Includes:

• 1 x QFN48 / QFN44 to DIP Double-Sided Adapter PCB

FREQUENTLY ASKED QUESTIONS (FAQ)

1. Can I mount components on both sides at once? No, the through-holes for the DIP headers are shared; you should only mount one component per board.

2. What is the lead pitch for this board? Both sides feature a precision 0.5mm lead pitch.

3. Will this fit a standard breadboard? Yes, it converts the SMD pins to standard 2.54mm spacing for all breadboards.

4. Are the header pins included? No, 2.54mm male header pins are sold separately.

5. What are the dimensions of the PCB? The board is a square measuring 25.4mm by 25.4mm.

6. Does it have a thermal pad? Yes, both sides include a central exposed pad for chips requiring a thermal or ground connection.

7. Which side is for the 44-pin chip? Use the side labeled "44 Pin Side" with the 5.64mm center pad.

8. What size are the DIP rows? The output headers are spaced at 17.78mm apart.

9. Do I need a special iron for this? A hot air rework station is highly recommended for leadless QFN packages.

10. How do I identify Pin 1? Pin 1 is indicated by a white dot or square pad on the silk screen.

11. Is the PCB material heat-resistant? Yes, the FR-4 material is rated for standard soldering temperatures.

12. Can I use this for PQFP packages? Yes, it supports PQFP, LQFP, and QFN packages with a 0.5mm pitch.

13. How many pins are broken out? Up to 48 pins can be broken out to the standard DIP spacing.

14. What is the diameter of the output holes? They are sized for standard 2.54mm pin headers.

15. What color is the PCB? The standard board is green with white silk screening.

16. Is there a mounting hole? No, the board is held in place by its header pins.

17. Can I reuse the board? If the component is desoldered carefully with hot air, the PCB can be reused.

18. What gauge wire fits the holes? Standard 22AWG solid wire or 2.54mm header pins are ideal.

19. What is the center pad size for the 48-pin side? It is approximately 6.07mm wide.

20. Why are there two different side designs? Different high-density ICs use varying pin counts and center pad sizes; this dual-sided design maximizes compatibility.
