SOP32 QFP32 to DIP32 Adapter PCB - 0.8mm Double-Sided SMD Converter

Specifications

• Board Dimensions: 25mm x 25mm

• PCB Thickness: 1mm

• Material: High-quality FR-4 Glass Fiber

• Side 1 (SOP): 0.8mm lead pitch

• Side 2 (QFP): 0.8mm lead pitch

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

• Pin Count: 32 Pins

Key Applications & Projects

• Microcontroller Evaluation: Test 32-pin micro-packaged controllers like the ATMega32 series on a breadboard.

• Memory Interfacing: Rapidly break out 32-pin SMD flash or SRAM chips for data recovery or firmware testing.

• Signal Processing: Evaluate high-pin-count SMD audio or data converters in traditional through-hole circuit designs.

Unlock New Capabilities (Project Evolution)

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

• Effort Level: Intermediate. Requires steady hands and basic SMD soldering techniques (or hot air rework for the QFP side) to mount the chip and the 2.54mm headers.

Package Includes:

• 1 x SOP32 / QFP32 to DIP32 Double-Sided Adapter PCB

FREQUENTLY ASKED QUESTIONS (FAQ)

1. Can I mount chips 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 both sides? Both the SOP and QFP sides feature a standard 0.8mm lead pitch.

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

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

5. What are the physical dimensions of the board? The PCB is a square measuring 25mm by 25mm.

6. What is the thickness of the PCB? It is 1mm thick.

7. Is it compatible with TQFP32? Yes, the QFP side is specifically designed for 0.8mm pitch TQFP32 and LQFP32 packages.

8. Can I use this for chips with fewer than 32 pins? Yes, as long as the pitch matches, you can center smaller chips (like SOP28 or QFP24) on the pads.

9. Do I need a special iron for this? A fine-tip iron or hot air rework station is recommended for the 0.8mm pitch pads.

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

11. Is the PCB material heat-resistant? Yes, the FR-4 material is designed for standard leaded or lead-free soldering temperatures.

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

13. Are the pads pre-tinned? Yes, the pads feature high-quality plating for easy solder wetting.

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

15. Can I use this with a DIP socket? Yes, once headers are attached, it can be plugged into a standard 32-pin wide DIP socket.

16. What is the spacing between the two rows of DIP pins? It is standard 0.6-inch (15.24mm) wide row spacing.

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

18. Can I reuse the board? Yes, if the component is desoldered carefully (ideally with hot air), the PCB can be reused.

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

20. Why are there two different side designs? Modern 32-pin ICs use various standardized geometries (rectangular SOP vs square QFP); this board maximizes compatibility for both.
