SOP20 SSOP20 to DIP20 Adapter PCB - 0.65mm & 1.27mm Double-Sided Converter

Specifications

• Board Dimensions: 25.4mm x 17.8mm

• Material: High-quality FR-4 Glass Fiber

• Pitch 1 (Front): 1.27mm (for SOP20/SOIC20)

• Pitch 2 (Back): 0.65mm (for SSOP20/TSSOP20)

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

• Pin Count: 20 Pins

Key Applications & Projects

• Bus Interface Testing: Ideal for testing surface-mount bus transceivers or shift registers (like the 74HC245) on a breadboard.

• Microcontroller Breakout: Evaluate 20-pin micro-packaged controllers for easy wiring to an Arduino or ESP32 development rig.

• Component Evaluation: Test 20-pin SMD motor drivers or power management ICs on standard solderless breadboards.

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 prototype boards during the development phase.

• Effort Level: Intermediate. Requires steady hands and basic SMD soldering techniques to mount the chip and the 2.54mm headers

Package Includes:

• 1 x SOP20 / SSOP20 to DIP20 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 SOP20? The SOP side features a standard 1.27mm pitch.

3. What is the lead pitch for TSSOP20? The SSOP side features a 0.65mm pitch.

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

5. What are the dimensions of the PCB? The board measures 25.4mm in length and 17.8mm in width.

6. Does it come with header pins? No, 2.54mm male headers must be purchased separately.

7. Which side is for SOIC20? Use the 1.27mm pitch side.

8. Is it compatible with MSOP20? Yes, most MSOP20 chips with a 0.65mm pitch will fit the SSOP side.

9. Can I use this for chips with fewer than 20 pins? Yes, as long as the pitch matches, you can center smaller pin-count chips (like SOP14 or SOP16) on the pads.

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

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

12. Do I need a special iron for the 0.65mm side? A fine-tip soldering iron or hot air station is recommended for the smaller pitch.

13. Is this a "narrow-body" or "wide-body" adapter? The pads are designed to accommodate standard SOP20 and SSOP20 package widths.

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

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

16. Can I use this with a DIP socket? Yes, once headers are attached, it can be plugged into a standard 20-pin wide DIP socket.

17. What is the row spacing for the DIP output? It is standard 0.6-inch (15.24mm) spacing.

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

19. Can I reuse the board? Yes, if the component is desoldered carefully, the PCB can be reused.

20. Why are there two different side designs? Different IC standards use different pitches; this dual-sided board maximizes compatibility for the two most common 20-pin SMD standards.
