- 1× SOP8 to DIP8 Programming Socket — Converts SOP8 chips to DIP8 footprint for use in standard ZIF sockets
Key Features
- Supports in-circuit BIOS chip programming via SOP8 test clip — no desoldering required
- CH341A programmer with gold-plated contacts for stable, low-resistance connections
- 1.8V adapter socket safely handles low-voltage flash memory chips
- SOP8-to-DIP8 burn-in socket allows off-board chip programming in a standard programmer
- Compatible with common BIOS/EFI flash chips used in laptops, tablets, and desktop motherboards
- Plastic housing — lightweight and durable
How to Use the SOP8 Test Clip
- Identify Pin 1 — Locate the small dot on the BIOS chip. The colored stripe on the test clip cable corresponds to Pin 1. Match them to avoid reversed connections.
- Connect to the programmer — Plug the test clip cable into the CH341A adapter board, ensuring each pin aligns correctly.
-
Open programming software — Connect the CH341A to your PC via USB. Launch your BIOS programming software and follow these steps:
- Read & verify chip information is detected
- Erase (this may take 30–60 seconds)
- Blank check to confirm erase
- Open and select your .BIN firmware file
- Program (allow a few minutes to complete)
- Verify — the process must pass verification before proceeding
- Reconnect and test — After programming, reconnect the board's power supply and power on to confirm successful flashing.

Frequently Asked Questions
Q: What chips is the SOP8 Test Clip Kit compatible with?
A: This SOP8 test clip kit is compatible with most standard SOP8-packaged BIOS and EFI flash memory chips found in laptops, tablets, and desktop motherboards. The CH341A programmer supports a wide range of 25-series and 24-series flash chips. Use the included 1.8V conversion socket for chips rated at 1.8V logic levels.
Q: Do I need to desolder the BIOS chip to program it?
A: No. The SOP8 test clip is specifically designed for in-circuit programming — it clamps directly over the chip on the board, so no desoldering is necessary. This makes it much faster and reduces the risk of damaging the PCB or surrounding components.
Q: What programming software should I use with the CH341A programmer?
A: The CH341A is widely supported by free tools such as AsProgrammer, NeoProgrammer, and CH341A MiniProgrammer software. These applications allow you to detect the chip, erase, program, and verify in a straightforward step-by-step workflow.
Q: Why would I need the 1.8V conversion socket?
A: Many modern flash memory chips — especially those found in ultrabooks and tablets — operate at 1.8V logic levels. Connecting these chips directly to a standard 3.3V programmer can permanently damage them. The included 1.8V conversion socket steps down the voltage, making it safe to program low-voltage chips with the CH341A.
