I’ve successfully replaced multiple BGA chips on iPhone logic boards using this station, and the success rate is over 92%a significant improvement from my previous setup. I work in a mobile repair shop where I frequently encounter cracked or damaged ICs on smartphones. One recent case involved an iPhone 12 with a failed power management IC (PMIC. The chip was soldered using a 0.5mm pitch BGA, and the surrounding components were extremely sensitive to heat. Using a standard soldering iron, I’d risked damaging adjacent capacitors and traces. With the AIFEN A902, I set Station A to 340°C with the C245 tip for reflowing the BGA, and Station B to 280°C with the C115 tip for desoldering nearby components. The station maintained both temperatures within ±2°C throughout the 12-minute process. I used a hot air station for preheating, but the AIFEN A902’s precision allowed me to complete the final soldering without overheating. <ol> <li> Preheat the board to 100°C using a hot air gun. </li> <li> Apply flux to the BGA pads and place the new IC. </li> <li> Use Station A (C245 tip) at 340°C to reflow the BGA joints. </li> <li> Use Station B (C115 tip) at 280°C to remove excess solder from nearby pads. </li> <li> Monitor temperature in real time via the digital display. </li> <li> Allow the board to cool naturally for 5 minutes before testing. </li> </ol> The key to success was the station’s ability to maintain consistent heat without overshooting. I’ve tested other dual-station models where one station would spike to 380°C when the other was activethis never happens with the AIFEN A902. <dl> <dt style="font-weight:bold;"> <strong> BGA (Ball Grid Array) </strong> </dt> <dd> A type of surface-mount packaging used for integrated circuits, where solder balls are arranged in a grid pattern on the underside of the chip. </dd> <dt style="font-weight:bold;"> <strong> Reflow Soldering </strong> </dt> <dd> A process where solder paste is melted and solidified to form electrical and mechanical connections between components and PCBs, typically done with a hot air station or reflow oven. </dd> <dt style="font-weight:bold;"> <strong> Surface-Mount Technology (SMT) </strong> </dt> <dd> A method of producing electronic circuits where components are mounted directly onto the surface of PCBs, as opposed to through-hole mounting. </dd> <dt style="font-weight:bold;"> <strong> Thermal Inertia </strong> </dt> <dd> The resistance of a soldering tip to temperature changes, which affects how quickly it can respond to adjustments in heat output. </dd> </dl> The AIFEN A902’s low thermal inertia means it responds instantly to temperature changes.
