RF4 RF-R6B Diagonal Hot Air Gun Nozzle Set

Diagonal Hot Air Gun Nozzle Set Built for Microscope Rework

The RF4 RF-R6B is a diagonal hot air gun nozzle set for technicians who rework boards under a microscope. A straight nozzle puts the gun body between your eyes and the chip. This set bends the airflow off-axis, so you keep the IC, the solder edge, and the flux in view for the whole job. You get six metal nozzles in one set, so you match the opening to the chip instead of heating the whole board.

Nozzle Sizes and Airflow Control

RF4 shows six sizes for this set: 4 mm, 5 mm, 6.4 mm, 8.4 mm, 10 mm, and 12.7 mm. Pick the smallest nozzle that covers the full package. A tight opening keeps heat on the target and away from capacitors, connectors, and plastic parts beside it. A wide opening spreads heat across a bigger chip so the solder under it melts evenly.

Hot air work punishes the wrong nozzle. An oversized opening lifts neighbouring small components. An undersized one leaves cold corners and tears pads. Keep the full range on your bench and swap nozzles as the repair changes.

360° Rotation and a Clear Sightline

The nozzle rotates through 360°. You aim the airflow from any side of the chip without twisting the gun or your wrist. When a tall component blocks one approach, rotate the nozzle and come in from another direction.

The curved shape clears the line of sight between your eyes and the work area. That matters under a microscope, where you watch the solder reflow and lift the chip at the right moment. It also helps in training sessions and live streams, where viewers need to see what you see.

Fit and Installation

RF4 designed the RF-R6B for Quick-style hot air guns. Distributors list it for the 861DW and 861Pro hot air rework stations. Installation takes seconds. If you run a different hot air gun, check the outlet size before you order and confirm the fit instead of assuming it.

Where It Fits on Your Repair Bench

This nozzle set belongs in the hot air stage of a board repair. A typical workflow starts with diagnosis. You check the board with a multimeter, find the faulty section, and decide whether the fault needs an IC change. You secure the board in a PCB holder, apply flux, and heat the chip through the diagonal nozzle while you watch under the microscope. Once the chip lifts, you clean the pads and reball or replace it.

Technicians in Pakistan use this kind of nozzle on dead phone repairs, charging issue boards, and display problem boards where a small IC sits near other components. The diagonal angle lets you reach those crowded areas without blocking your view.

Pair the set with a hot air station, a microscope, a PCB holder, and a reballing kit from the same category range. If you still work with a basic hot air gun, this set upgrades your control without a new station. Set your temperature and airflow for the job, keep the nozzle moving in small circles, and stop heating as soon as the solder flows. Short, controlled heat protects the board and the chip.
