Soldering iron and solder:

When it comes to soldering the charging port on a Samsung E1200 or any other electronic component, having the right soldering iron and solder is crucial. Here’s what you need to know about these tools:

Soldering Iron:

  1. Wattage: For most electronics and small soldering tasks, a low to mid-range wattage soldering iron is suitable, typically in the range of 25 to 60 watts. A higher wattage iron may be necessary for larger projects, but for phone repairs, a lower wattage iron is sufficient.
  2. Temperature Control: If possible, use a soldering iron with adjustable temperature settings. This allows you to set the right temperature for the specific solder you’re using and prevents overheating delicate components.
  3. Tip Compatibility: Make sure the soldering iron you choose has interchangeable tips. Different tips are used for various soldering tasks, and having options can be helpful.
  4. Quality: Invest in a good-quality soldering iron from a reputable brand. A quality iron heats up quickly and maintains a stable temperature, making soldering more precise.


  1. Type: There are various types of solder available, but for most electronics work, including phone repairs, you should use rosin-core solder. Rosin-core solder contains a flux core that helps the solder flow and bond properly.
  2. Diameter: Solder comes in different diameters, typically measured in inches or millimeters. For small electronics like mobile phones, a thin solder with a diameter of around 0.02 inches (0.5 mm) is suitable.
  3. Lead-Free vs. Leaded Solder: Consider using lead-free solder, as it’s better for the environment and your health. However, leaded solder may still be more readily available and easier to work with.

Safety Precautions:

  1. Ventilation: Soldering can produce fumes, so ensure you work in a well-ventilated area or use a fume extractor if available.
  2. Eye Protection: Wear safety goggles or glasses to protect your eyes from solder splatter and fumes.
  3. Heat Protection: Use heat-resistant surfaces and mats to protect your workspace and prevent accidental burns.
  4. Static Protection: If working with sensitive electronic components, consider using an anti-static mat and wrist strap to prevent electrostatic discharge (ESD) damage.
  5. Proper Storage: Store soldering irons and solder in a safe and dry place when not in use to prevent damage or accidents.

Before you begin soldering, make sure you practice your soldering skills on scrap components if you’re not experienced. It’s essential to solder carefully and precisely, as excessive heat or poor soldering techniques can damage the phone’s components. If you’re not confident in your soldering abilities, consider seeking assistance from a professional technician or a repair shop.

Small prying tools:

Small prying tools are essential for safely opening electronic devices like mobile phones without damaging the delicate components or the casing. These tools come in various shapes and sizes, and they are often made of plastic or non-conductive materials to prevent any accidental short circuits. Here are some common types of small prying tools you can use for phone repair:

  1. Plastic Spudgers: Plastic spudgers are versatile and safe for most electronic devices. They have a flat, wedge-shaped tip that allows you to gently pry open plastic casings without scratching or damaging the surface.
  2. Nylon Spudgers: Nylon spudgers are similar to plastic spudgers but are made from nylon, which is even less likely to scratch or leave marks on the device’s surface.
  3. Opening Picks: Opening picks are thin and flexible plastic tools with a rounded or wedge-shaped end. They are designed to slide between the seams of a device’s casing and gradually pop it open.
  4. Metal Spatula Tools: These tools have thin, flat metal blades on one end that can be used for prying. Be cautious when using metal tools, as they can potentially damage delicate components or scratch the phone’s surface.
  5. Guitar Picks: Thin guitar picks, especially those made of plastic or nylon, can work as makeshift prying tools. They are thin and flexible, making them suitable for getting between the seams of a phone’s casing.
  6. Plastic Picks: Some specialized phone repair kits come with plastic picks designed for opening specific phone models. These may have shapes and sizes tailored to fit certain devices.

When using prying tools, remember to:

  • Start with the least force necessary and gradually increase pressure if needed.
  • Work your way around the edges of the phone, gently releasing the clips or adhesive that holds the casing together.
  • Avoid using excessive force, as this can result in cracking or breaking the phone’s plastic casing or damaging internal components.
  • Be especially careful near fragile components like the display, buttons, or camera modules.

Always prioritize safety and patience when using prying tools. If you’re unsure about the best approach for opening your specific phone model, consult the phone’s repair manual or seek guidance from online tutorials or a professional technician.

Steps to Repair the Charging Pin:

  1. Power Off the Phone: Turn off the Samsung E1200 and remove the battery if possible.
  2. Remove Screws: Use the appropriate screwdriver to remove any screws securing the phone’s back cover.
  3. Open the Phone: Carefully pry open the phone using small prying tools. Start from the seam and work your way around the edges. Be gentle to avoid damaging the internal components or the plastic casing.
  4. Locate the Charging Port: Once you have the phone open, locate the charging port. It’s typically connected to the mainboard via a ribbon cable.
  5. Inspect the Charging Port: Use a magnifying glass or a good light source to inspect the charging port. Check for any visible damage or loose connections.
  6. Repair or Replace: Depending on the damage, you may have two options: a. Repair: If the charging pin or the connections are damaged, you can attempt to solder the connections back together if you have soldering skills. This requires a steady hand and precision soldering. b. Replace: If the charging port is severely damaged or cannot be repaired, you’ll need to replace it. Carefully desolder the old charging port from the mainboard and solder the new one in its place.
  7. Reassemble the Phone: After repairing or replacing the charging port, reassemble the phone in reverse order. Make sure all the components are properly aligned and secured.
  8. Test: Reinsert the battery and power on the phone. Test if it charges properly. If it does, you have successfully repaired the charging pin.
  9. Final Check: Make sure all buttons, functions, and the screen work correctly. Ensure that the phone is charging reliably.

Remember that repairing a charging pin can be tricky, and if you’re not confident in your skills, it’s best to seek help from a professional technician or a phone repair shop. Additionally, be cautious when working with small electronic components, as they are delicate and can easily be damaged.
