❓ Frequently Asked Questions
What is the Tigris Charging IC and what does it do?
The Tigris Charging IC, officially designated SN2600B by Texas Instruments but commonly called Yangtze in repair communities, is Apple's proprietary charging management integrated circuit used in iPhone XS, XS Max, XR, and iPad 8 (2020) devices. This critical component sits on the logic board and controls all aspects of power delivery and battery charging. Its primary functions include managing power flow from the Lightning port to the battery, implementing Apple's proprietary charging protocols for optimal battery health, communicating charging status and battery health data to iOS, providing overcurrent and overvoltage protection to prevent damage, and enabling fast charging negotiation with compatible power adapters. When this IC fails, the device may exhibit various charging problems including complete failure to charge, extremely slow charging, fake charging where the icon appears but battery percentage does not increase, rapid battery drain even when plugged in, or the device becoming very hot during charging attempts. The IC is a BGA (Ball Grid Array) package requiring professional micro-soldering equipment and skills to replace.
What symptoms indicate a faulty Tigris IC?
A faulty Tigris charging IC can manifest through several symptoms that experienced technicians learn to recognize. The most common symptom is complete failure to charge where the device shows no response when connected to a known-good charger and cable, while other devices charge normally with the same accessories. Fake charging occurs when the charging icon appears on screen but the battery percentage does not increase or increases extremely slowly. Some devices may show erratic battery percentage readings, jumping between values or dropping suddenly. Excessive heat during charging attempts indicates the IC may be partially shorted, drawing too much current. Very slow charging that takes many hours longer than normal suggests degraded IC performance. Battery drain while plugged in, where the device loses charge despite being connected to power, points to charging circuit failure. Before diagnosing Tigris IC failure, technicians should first rule out other causes including faulty charging port flex cable, damaged Lightning port connector, bad battery, or software issues. Proper diagnosis requires DC power supply testing to measure current draw behavior.
Why does this IC require professional micro-soldering?
The Tigris SN2600B IC requires professional micro-soldering because it is a BGA (Ball Grid Array) package component with dozens of tiny solder balls on its underside that connect to equally tiny pads on the logic board. These connections are invisible once the IC is placed, requiring precise temperature control and technique to achieve proper solder joints without damaging adjacent components or the multilayer PCB. The installation process involves carefully removing the failed IC using a hot air rework station with precise temperature and airflow control, cleaning all residual solder from the board pads without damaging traces, applying fresh solder balls to the replacement IC using a stencil (reballing), precisely aligning the new IC under microscope magnification, reflowing the solder connections at controlled temperatures, and verifying proper installation through electrical testing. This work requires specialized equipment costing thousands of dollars and significant training to master. Improper technique can cause bridged solder joints, lifted pads, damaged traces, or thermal damage to surrounding components. This is definitively not a DIY repair.
What equipment is needed for Tigris IC replacement?
Professional Tigris IC replacement requires specialized motherboard repair equipment that most repair shops do not possess. Essential equipment includes a quality hot air rework station with precise temperature control and various nozzle sizes for controlled heating during IC removal and installation. A stereo microscope with adequate magnification is mandatory for inspecting solder joints and precise IC alignment. A PCB preheater is necessary to bring the board to a base temperature before localized heating, preventing thermal shock and board warping. High-quality flux designed for BGA work helps solder flow properly and prevents oxidation. A reballing station and appropriate stencils are needed to apply fresh solder balls to the replacement IC. Precision tweezers and placement tools position the IC correctly. IPA (isopropyl alcohol) and cleaning tools remove flux residue after installation. A DC power supply allows testing current draw before and after repair to verify success. Additional helpful equipment includes thermal cameras to monitor heat distribution and PCB holders to secure the board during work. This equipment represents a significant investment beyond standard phone repair tools.
Is this IC compatible with all iPhone models?
No, this specific Tigris IC (SN2600B/Yangtze) is only compatible with iPhone XS, iPhone XS Max, iPhone XR, and iPad 8 (2020). Different iPhone generations use different charging management ICs with different specifications and pinouts. Using the wrong IC model will not work and could potentially damage the logic board. Earlier iPhones like iPhone X and iPhone 8 use different charging IC designs. Later iPhones including iPhone 11 and newer models use updated versions of the charging management system with different IC specifications. Before ordering, technicians must confirm the exact IC model required for their specific repair by checking schematics or identifying the existing IC on the board. The IC model number is typically printed on the chip itself, though it may require microscope magnification to read. We stock various Tigris IC versions for different iPhone models. If you are unsure which IC you need, contact us with your device model for verification before ordering.
Why is there no warranty on IC components?
IC components are sold without warranty due to the highly specialized nature of motherboard-level micro-soldering and the impossibility of determining post-sale handling. Unlike screen or battery replacements where installation is relatively straightforward, IC replacement success depends almost entirely on the technician's skill level, quality of equipment used, proper technique during removal and installation, and correct diagnosis of the original problem. A perfectly functional IC can be destroyed through improper handling, incorrect temperature profiles, ESD (electrostatic discharge) damage, or poor soldering technique. Conversely, installation problems like bridged pins, cold solder joints, or lifted pads can cause a properly installed IC to malfunction. We thoroughly test every IC before shipping to ensure it leaves our facility in working condition. However, once the IC is in the customer's possession, we cannot control handling, storage conditions, or installation quality. This is industry standard practice for BGA IC components. Professional technicians understand these limitations and factor potential failures into their repair pricing and processes.
How do I properly diagnose Tigris IC failure?
Proper diagnosis of Tigris IC failure requires systematic testing to rule out other common causes of charging problems. Start by testing with known-good charger and cable combinations to eliminate accessory issues. Inspect the Lightning port for debris, corrosion, or bent pins. Test with a new charging port flex cable if port damage is suspected. Check battery health and test with a known-good battery. Use a DC power supply to measure current draw behavior at different voltage levels. A healthy board should show specific current draw patterns during boot sequence. Abnormal current draw, no current draw, or excessive current draw can indicate different fault conditions. Check for short circuits on power rails using a multimeter in diode mode. Inspect the board under microscope for obvious physical damage, burnt components, or corrosion around the charging circuit. Thermal imaging can reveal components drawing excessive current. Only after ruling out charging port, battery, and other component issues should Tigris IC replacement be considered. Replacing the IC without proper diagnosis may result in the same symptoms if another component was actually at fault.
Can water damage cause Tigris IC failure?
Yes, water damage is one of the most common causes of Tigris IC failure in iPhones. When liquid enters the device, it can reach the logic board and cause corrosion on IC pins, solder joints, and PCB traces over time. The charging circuit is particularly vulnerable because the Lightning port provides a direct entry point for liquid, and the Tigris IC is located near this area of the board. Water damage may not cause immediate failure but can progressively degrade connections until charging problems develop. Signs of water damage affecting the charging circuit include intermittent charging that gets progressively worse, corrosion visible around the IC or nearby components, green or white oxidation on the board, and charging problems that developed after known or suspected liquid exposure. When replacing a Tigris IC on a water-damaged board, technicians must also thoroughly clean the entire board to remove all corrosion, inspect and repair any damaged traces, and verify no other components were affected. Simply replacing the IC without addressing underlying corrosion will often result in continued problems or repeat failure.
