In this part of the video, the speaker discusses trace damage and demonstrates repairing traces using different thicknesses of wires. Thicker wires are used for thicker traces, while finer enamel-coated copper wires are used for thinner traces. The speaker emphasizes matching wire width to the trace for proper signal conduction. The tutorial includes a cleanup operation to remove loose bits before repairing the traces. The speaker demonstrates removing curled-up traces by peeling them off and scoring the trace for clean separation. The process is shown to be meticulous but effective, leading to impressive repair results.

In this segment of the video, the speaker emphasizes the importance of creating a solid grounding point for the new wire. They demonstrate scoring the trace to prevent it from going beyond a certain point when peeling it back. This process is repeated for multiple points, ensuring a clean break at the desired location. The goal is to establish solid points for soldering the new wires, resulting in a more organized and professional look to the project.

In this part of the video, the focus is on tidying up loose ends and cleaning up traces to create solid soldering points for wires. The speaker demonstrates scraping back the traces to create soldering points about a millimeter or two deep and then applying flux to tin them, creating sturdy points for wire attachment. The process ensures uniformity and a solid joint for soldering wires in the next steps of the project.
00:09:00
In this part of the video, the speaker demonstrates how to prepare traces for soldering by scraping them back and tinning them. The main steps include scraping back about a millimeter or two of the trace, tinning it with solder, and cleaning up. The speaker emphasizes the importance of matching the thickness of the trace with the new wire when soldering. Different wire types are used for different trace thicknesses. The speaker shows how to fit enamel-coated copper wire onto narrower traces and emphasizes the significance of proper wire thickness matching for successful soldering. The process involves tinning the traces and then attaching the new wires.
00:12:00
In this segment of the video, the speaker explains two methods to remove enamel from wires. They demonstrate scraping or burning off the coating carefully to expose the copper wire, ensuring the wire matches the trace width on the board. They emphasize shaping the wire to match the original trace indent, then carefully scraping to achieve the desired wire length. The speaker also discusses pre-tinning the wire ends and using captain tape to hold the wire in place before soldering. These steps ensure proper wire preparation for successful soldering.
00:15:00
In this segment of the video, the speaker demonstrates soldering techniques on wires. They show how to apply flux, solder, and create solid joints on the wires. The importance of flux in aiding the soldering process is emphasized. The speaker pre-tins the wire ends before soldering and ensures the joints are rock solid. They mention the difficulty of working with small wires but stress the importance of creating strong joints. Additionally, the speaker discusses the process of bonding wires down and preparing wires for connection to traces on the board.
00:18:00
In this segment of the video, the speaker demonstrates how to repair traces on a circuit board. They prepare the wire and solder it in position, carefully scalpel-blading the wire to avoid damaging the board. The process involves adding flux, soldering the wire quickly, and ensuring a good joint without the wire falling away. The speaker emphasizes being gentle and quick during the process. Once the short wire repairs are done successfully, they move on to longer trace repairs, showing the preparation steps before soldering.

In this part of the video, the speaker demonstrates how to create a customized wire for a PCB by bending solder into the shape of an existing trace. They then cut a wire to match the length of the solder, strip both ends, and solder the wire onto the board following the trace pattern. This method ensures an exact fit and alignment. The speaker uses Captain tape to hold the wire in place, solders the wire onto the board, and then applies electrical glue to secure it further. The process results in a new wire trace that matches the original pattern on the PCB.
00:24:00
In this part of the video, the presenter demonstrates applying solder to wires by placing a little piece of solder over the wires in different spots to secure them. They emphasize not needing too much solder and recommend placing a piece across both wires, allowing it to set. The method involves creating several spots of solder at specific areas on the wires and waiting for them to set. The presenter mentions taking photos of the end results and expresses hope that viewers have learned something useful from the tutorial.
