RF4 RF-FT02 Mini Motherboard Chip Repair Fixture

RF-FT02 Motherboard Fixture for CPU and IC Rework
RF4 designed the RF4 RF-FT02 as a compact, two-way holder for one task: keeping a phone mainboard locked in place while you work on CPU, BGA, and IC areas. The RF-FT02 motherboard fixture grips the board by its edges and suspends it above the base, so your hands stay free for hot air, tweezers, and the iron. The body measures about 66 × 92.5 mm. It fits under a stereo microscope without crowding the bench.
Suspension Design That Controls Heat Loss
A board resting flat on a metal or silicone base gives up heat to that surface. The RF-FT02 lifts the motherboard and touches it only at the clamped edges. Less contact means less heat lost through conduction. Your hot air reaches reflow temperature on the target chip faster, and you spend less time holding the nozzle over one spot. This matters most with lead-free solder, which melts at a higher temperature than leaded alloys and pushes you toward longer heating.
Shorter dwell time matters on dense boards. It helps protect neighboring capacitors, shields, and the underfill around chips you plan to leave untouched. When you lift a CPU on a dead phone or take on an IC change karna job on a charging issue board, the suspended position also gives you even heating across the chip footprint. Even heating reduces the risk of lifted pads and torn traces during removal.
Two-Way Clamp With Internal Bevel Grip
The fixture adjusts in two directions. You set the jaws to the board’s width and length instead of forcing the board into a fixed slot. Internal bevels on the clamping faces seat the board edge firmly and resist lift and side slip.
That grip holds when the work gets physical. You can drag solder wick across pads, scrape old underfill, or run a jumper across a broken trace (jumper lagana) without the board shifting under the microscope. No tape. No rubber bands. No re-focusing after every push of the tweezers.
Steady positioning also helps with hardware fault diagnosis. You clamp the board, connect your DC power supply leads, and trace a short circuit with your multimeter while the board stays level.
Where the RF-FT02 Motherboard Fixture Fits in Your Workflow
The RF-FT02 sits at the center of board-level work. Inspection starts under the microscope. Chip removal follows with a hot air station. Pad cleaning and tinning run on a soldering station with flux and wick. If the chip needs new balls, a reballing kit and stencil take over before you seat the IC again. Final checks happen on the test bench with a multimeter and power supply. With the RF-FT02 motherboard fixture holding the board through every stage, you avoid re-clamping between steps.
Pair it with tools from the same workflow: Hot Air Stations, Soldering Stations, Microscopes, Reballing Kits, and Multimeters. You can find more board holders in the PCB Holders category. For larger boards or work that benefits from a heat-resistant glass base, the RF4 RF-FT07 dual-axis glass fixture is the natural upgrade path.
Who Should Use the RF-FT02
Board-level technicians who handle CPU, PMIC, and network IC jobs daily get the most from this holder. Repair shops that run several boards at once can keep a few units on the bench, one per job. Training institutes benefit too: a fixed, suspended board lets students focus on heat control and soldering technique instead of chasing a sliding PCB. The small footprint keeps setup fast, whether you fix a network issue on one board or a display problem on the next. The RF-FT02 motherboard fixture also handles small non-phone boards, including automotive ECU PCBs where you solder microcontrollers and power ICs.
