Replacing an iPhone screen with an OEM used screen requires a critical step—transplanting the IC (Integrated Circuit) to prevent the display from showing the “Unknown Part” message. When using OEM screens harvested from other iPhones, it is essential to grind the IC beforehand to ensure proper transplanting and seamless integration.

Tools Required:
Before we begin, here are the essential tools required for IC grinding and transplanting:
- Precision grinding tool
- IC Stencil
- Soldering iron
- Blade or other fine-edged tool
- Solder mask or coating solution
- Inspection tools (microscope, magnifier, etc.)
Why Is IC Grinding Necessary Instead of Heating?
Many may wonder why the IC must be ground off rather than removed through heating. The primary reason is that applying excessive heat can severely damage the iPhone screen , rendering it unusable. Grinding ensures that the IC is carefully removed without compromising the integrity of the display.
Key Considerations During IC Grinding
One of the most common operational errors involves damaging adjacent components. For instance, in the iPhone 13 Mini, the IC is located very close to the touch IC. To avoid damaging nearby components, it is crucial to move the screen slowly and carefully during the grinding process.
Additionally, Reformtech recommends using an IC stencil to protect the flex cables from unintentional harm. However, even with these precautions, technicians may still encounter challenges, such as solder bridges.
Addressing Solder Bridges
Solder bridges can occur when excessive or uneven force is applied during the grinding process. These unintended solder connections can cause functional issues if not addressed properly. To prevent or fix solder bridges:
- Use a precision blade or grinding tool to gently remove excess solder.
- Alternatively, apply the tip of a soldering iron to melt the excess solder and reshape connections.
- Maintain a gentle and controlled pressure throughout the grinding process.
- Regularly inspect the pads during grinding to ensure proper force application and prevent unnecessary wear.
Additional Considerations: Exposed Copper Pads
Apart from solder bridges, another issue technicians may encounter when grinding ICs on second-hand screens is the exposure of bare copper pads. The protective layer covering the pads, typically electroplating or a solder mask, can wear away during grinding, leaving the copper surface exposed.
To protect the exposed copper joints and ensure the longevity of the repair, apply a solder mask or protective coating. This step will help restore the integrity of the connections and prevent oxidation or further damage.
Final Steps: Transplanting the IC
Once the touch IC has been successfully removed from the faulty screen, it should be transplanted onto the OEM used screen. After completing the installation, power on the device and verify the repair in the Settings menu. If the “Unknown Part” message does not appear, it indicates that the IC grinding and transplanting processes were successfully executed.
