Specifications

• Board Length: 26mm

• Board Width: 13mm

• Material: High-quality FR-4 Glass Fiber

• Pitch 1 (Side A): 0.5mm

• Pitch 2 (Side B): 0.65mm

• DIP Output Pitch: Standard 2.54mm (0.1 inch)

• Number of Pins: 20 Pins

• Thermal Pad: Integrated center ground pad for heat dissipation

Key Applications & Projects

• Advanced Sensor Testing: Evaluate QFN-packaged accelerometers or digital gyroscopes on a breadboard.

• Power Supply Design: Test high-efficiency 20-pin buck/boost regulators.

• RF Component Evaluation: Prototype micro-packaged wireless modules or signal amplifiers.

Unlock New Capabilities (Project Evolution)

• Feature Upgrade: This board turns a leadless surface-mount chip into a removable plug-in unit, allowing for easy swapping between different test rigs or prototype boards during the optimization phase.

• Effort Level: Intermediate to Advanced. Requires fine-tip soldering or hot air rework skills due to the leadless nature of QFN packages.

Package Includes:

• 1 x QFN20 to DIP20 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; only one component should be mounted per board.

2. What are the two lead pitches available? One side is 0.5mm and the reverse side is 0.65mm.

3. Does it come with header pins? No, 2.54mm male header pins are sold separately.

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

5. What is the size of the PCB? The board measures 26mm by 13mm.

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

7. Is it compatible with QFN-16 chips? While designed for 20 pins, a 16-pin QFN with a matching 0.5mm or 0.65mm pitch can often be centered on these pads.

8. Do I need a special iron for this? A hot air rework station is highly recommended for QFN packages as they have no external leads.

9. How do I identify Pin 1? Pin 1 is clearly marked with a square pad and a numeral '1' on the silk screen.

10. What is the board material? It is made from high-quality green FR-4 glass fiber.

11. Are the pads gold-plated? These typically feature high-quality tin plating for easy solder wetting.

12. Can I use this for QFP packages? No, this is specifically for QFN (Quad Flat No-lead) packages.

13. What is the diameter of the output holes? They are standard 1mm holes designed for 2.54mm pin headers.

14. Is the PCB material heat-resistant? Yes, it is rated for standard leaded or lead-free soldering temperatures.

15. What is the spacing between the two rows of DIP pins? It is standard 0.4-inch or 0.5-inch spacing depending on the header orientation.

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

20. Why are there two different side designs? Modern ICs use various standardized pitches; this dual-sided board covers the two most common 20-pin QFN standards.
