1
Procurement & Preparation
- Procure all required Bill of Materials including G-Switch GT-USB-7051 vertical receptacles, Bourns MF-NSMF075 (or MF-MSMF075-2) resettable fuses, STMicroelectronics USBLC6-2SC6 ESD protection ICs, 2.54mm pitch header pins (TSW-108-07-G-S), and custom PCBs.
- Prepare the PCB stencil alignment and secure the bare PCB on an anti-static workstation using a vacuum table or jig.
2
Hardware Assembly & Wiring
- Apply Type 4 lead-free solder paste through the stencil onto the SMT pads for the GT-USB-7051 connector, Bourns MF-NSMF075 fuse, and USBLC6-2SC6 ESD protection IC.
- Place the G-Switch GT-USB-7051 vertical USB-C connector, Bourns MF-NSMF075, and USBLC6-2SC6 onto their respective paste-covered pads using pick-and-place tweezers.
- Run the populated PCB through a reflow oven following a standard SAC305 lead-free thermal profile to solder all SMT components securely.
- Insert the 2.54mm pitch header pins (TSW-108-07-G-S) into the through-hole breakout locations and hand-solder or wave-solder them on the bottom side of the board.
3
Firmware Setup
- Since this is a passive breakout board with no onboard programmable MCU, verify that required pull-down configuration channel (CC) resistors are correctly wired to ground for Type-C sink detection.
4
Testing & Calibration
- Perform an automated optical inspection (AOI) and manual visual check under magnification to inspect solder joints for cold joints, tombstoning, or bridging.
- Conduct electrical continuity and isolation testing using a digital multimeter to verify VBUS, GND, D+, D-, CC1, CC2, and Shield connections without short circuits.
- Perform a functional power and high-speed data test by plugging a USB-C cable into the vertical receptacle, drawing 3A load on VBUS to test thermal and overcurrent stability of the Bourns fuse, and passing high-speed data through the USBLC6-2SC6 protection IC.
