4. Disassembly the LCD display assembly. We observe with the microscope and find the J5800 has the obvious repairing marks, so we can have the connector J5800 replaced for a try.



5. Remove the logic board and attach it to PCB Holder. Stick connectors next to J5800 with high temperature adhesive tape. Apply some BGA solder paste flux to the and take down J5800 with Hot Air Gun.

6. Use the smart solder iron to solder tins, and clean with PCB Cleaner afterwards. Wait for the logic board to cool for 5 minutes and check its soldering situation. 

7. Reinstall the logic board and connect the battery and the iPhone LCD display assembly, then power on iPhone 8.

3. Put the solder wire and the iron tip togetherwhere the component lead and the Copper Track of the PCB meets. Melt enough solder at the junction. Make sure there are no bridges.

4. Welding should be bright and good shape. If you use lead-free solder, then even if the welding is correct, the welding will not shine.

5. Don't touch the PCB track too long with hot ait gun. Once the solder is melted, remove the iron immediately.

Necessary Solering Tools:

Soldering Station - Try to get a high quality brand ESD Safe Soldering Station if you are a professional, It's available for you to control the temperature and insert the soldering iron into the station. With soldering station, you will never worry about that the high temperature will damage components.

Soldering Iron - Try to buy a good quality ESD safety iron. A 50 Watt iron can weld any electronic component onto the PCB.

Solder Wick - It will help remove residuals on the PCB surface and the lead of the electronic component. This soldering assistant will help better soldering.

Other consumables may be required to dismantle the core, PCB Holder, conductive pen, magnetic pen, clean sponge and so on.



Soldering Tips:

- Use wet sponge to clean the iron head before and after the soldering iron.

- put some phone soldering wire on the top of the soldering iron.  If the wire is melted immediately, it means that the iron is ready for welding.

- Never touch the iron head or the iron head. The tip temperature may be as high as 500 degrees Celsius, it will lead to severe burns and injuries.

- Always put a wet solder on the iron rack and clean the sponge.

- When the welding is finished, clean the tip with a clean sponge and leave some solder at the tip. This prevents oxidation of the tip and prolongs its service life.
