Stripping Ribbon Cable Plastic: A Step-By-Step Guide

how to strip plastic from ribbon cable

Ribbon cables are flat cables with multiple cords fixed together, often used to connect storage drives and motherboards in electronic devices. They are generally considered obsolete, but can still be found in some older devices like TVs, laptops, gaming systems, and printers. Removing ribbon cables requires careful attention to avoid damaging the delicate wires. Before removing a ribbon cable, it is important to measure its width and length and identify the cable type to ensure compatibility when purchasing a replacement. This article will provide a comprehensive guide on how to strip plastic from ribbon cables safely and effectively.

Identify the plastic clip or latch

Ribbon cables are typically found inside TVs, laptops, gaming systems, and printers. They are secured by a plastic clip or latch. To identify the plastic clip or latch, you must first locate the ribbon cable connection. This is usually found under the keyboard or back panel of a device.

The plastic clip or latch will be at the end of the ribbon cable, where it connects to the electronic device. It will appear as a horizontal strip of plastic with little rivets sticking out. There may also be two plastic notches on both sides of the cable clip.

If the ribbon cable has a connector, it may have a plastic locking tab around it. These are often used in large gaming consoles and mice.

To release the cable, you will need to gently lift or flip the clip or latch. Do not use a screwdriver or any other tool, as this may break the clip. Instead, use your hand or a plastic spudger tool.

Once the clip is unlocked, you can carefully pull the ribbon cable straight out of the connector, being careful not to bend or damage the cable.

Flip the clip to release the cable

Ribbon cables are generally considered obsolete, but you may still find them in devices like TVs, laptops, gaming systems, and printers. They are flat cables with multiple cords fixed together, and they are secured by a plastic clip.

To release the ribbon cable, locate the plastic clip or latch securing the cable. The cable clip is a horizontal strip of plastic with little rivets sticking out. It is usually found under the keyboard or back panel of the device. Once located, gently lift or flip the clip to release the cable. You can do this by placing your index finger in the middle of the rivets and gently pulling upwards while applying light pressure.

After releasing the clip, carefully pull the ribbon cable straight out from the connector to avoid bending or damaging it. Make sure to keep the cable straight as you pull it out to prevent any damage to the delicate wires.

When installing a new cable, ensure that it is inserted gently in the same orientation as the old one. Push the clip back down or flip it to lock the cable in place.

Pull the cable out

To pull the cable out, first, identify the plastic clip or latch securing the cable. Ribbon cables are usually secured by a plastic clip. If your cable has a connector, it may have two plastic notches on both sides of the cable clip that you need to push outward to release the cable. If not, proceed to the next step.

Next, gently lift or flip the clip to release the cable. Place your index finger in the middle of the rivets and gently pull upwards to unlock the clip. Be careful not to apply too much force as you may accidentally break off a piece of plastic.

Finally, carefully pull the ribbon cable straight out from the connector, ensuring you do not bend or damage the delicate wires. It is important to pull the cable out gently and slowly to avoid any damage to the cable or the device.

Use a Dremel tool to grind off the plastic

Using a Dremel tool to grind off the plastic from a ribbon cable is an effective method, but it requires precision and attention to detail. Here is a step-by-step guide on how to do it:

Firstly, ensure you have the right Dremel tool and attachments. The Dremel rotary tool is versatile and suitable for grinding plastic. It is recommended to use a Dremel model with adjustable speed settings, as this will give you greater control over the grinding process. Choose a cutting wheel attachment specifically designed for cutting plastic, such as the EZ476, or a multipurpose cutting wheel like the EZ409. Thinner cutting wheels will cut through plastic quicker but are more brittle, so thicker reinforced wheels may be preferable for ribbon cables.

Before you begin, ensure your workspace is clear and practice on scrap pieces of plastic to enhance your proficiency. Put on your safety gear, including eye protection and gloves, and ensure the Dremel tool is set to the appropriate speed. For cutting plastic, it is generally recommended to start at a moderate speed, between 10,000 and 15,000 RPM, to avoid melting the plastic.

Now you can start grinding. Gently position the cutting wheel along the marked cutting line on the ribbon cable and begin the grinding process. Apply a controlled amount of pressure, allowing the tool to execute the work. Avoid exerting excessive force as this can cause overheating and uneven cuts. Work in steady, smooth movements to create clean, straight cuts.

Finally, finish the edges of the ribbon cable. Use a grinding attachment to clean the edges and obtain a better-looking finish. A Dremel sanding disc, such as the Dremel 411 or a finer option like the Dremel 413, can be used for this purpose. Remember to regularly clean the cutting area to manage the accumulation of plastic dust and residue.

By following these steps and maintaining a slow and steady approach, you can effectively use a Dremel tool to grind off the plastic from a ribbon cable, achieving precise and clean results.

Replace the cable

To replace a ribbon cable, first, power off the device and unplug it from any power sources. Next, measure the width and length of the cable and note its type. If you need a replacement, purchase the exact type from the manufacturer to ensure compatibility. Remove the latches securing the case and access the internal components. Find the ribbon cable you need to remove, connecting the motherboard to drives or other peripherals. Ribbon cables are usually secured by a plastic clip. To remove the cable, gently lift or flip the clip to release it. When the clip is open, carefully pull the ribbon cable straight out of the connector, ensuring you do not bend or damage the delicate wires.

If your cable has a connector, you may need to crimp a new connector to the replacement cable. Ensure the connector is securely attached before inserting it into the port. Position the new ribbon cable so that it aligns correctly with the connector. Gently insert the cable into the connector until it is fully seated. Push the clip back down or flip it to secure the cable in place. Reattach the case cover and secure it with screws or latches. Plug in and power on the device to ensure the new cable is functioning correctly.

If you need to strip the insulation from the ribbon cable, there are a few methods you can try. One method involves using a solvent such as pure acetone to soak the end of the ribbon for a few minutes in a closed container. This should allow you to remove the insulation. Another method is to use a tool such as an adjustable Dremel tool with a small ball-ended diamond burr. Mark the length you need to strip with a fine-tipped pen, then slowly grind off the top layer from each contact one at a time, being careful not to go too deep.

It is important to note that ribbon cables are usually used with insulation displacement connectors and are not typically stripped. Additionally, regular wire strippers may not work on ribbon cables due to the unique construction of the insulator and conductor. Always exercise caution when working with electronics, and if you are unsure, it is best to consult a professional or seek further advice.

Frequently asked questions

Ribbon cables are secured by a plastic clip. To remove the cable, flip the clip up to release it. If the cable has a connector, you may need to crimp a new connector to the replacement cable.

A brief touch with an iron can help you scrape off the white plastic, but this always risks lifting a track.

This cable is almost certainly a Kapton substrate flexible PCB with an additional layer laminated on top. Take an adjustable Dremel tool, fit a small ball-ended diamond burr, and turn the speed down pretty slow. Take a fine-tipped pen and mark off the length you need to strip. Grind off the top layer from each contact one at a time.

You can strip a flat ribbon cable with pure acetone. Soak the end of the ribbon for a few minutes in a tiny closed container, so it doesn't evaporate.
