Copper Film Sheets and Kapton Polyimide Film are commonly used in the electrical and electronics industry for their excellent properties. Pyralux is a brand name for copper-clad laminates that are made of a flexible Kapton polyimide film coated with copper on one or both sides. Copper-clad laminates are commonly used in the manufacturing of printed circuit boards (PCBs) as they offer high flexibility and excellent electrical and thermal performance.
However, when it comes to etching, removing the Kapton Polyimide Film from Pyralux Copper Sheets can be a challenging task. The Kapton Polyimide Film is a tough, heat-resistant material that cannot be easily removed by conventional methods. Therefore, to remove the film, you will need to follow these steps:
Step 1: Cut the Pyralux Copper Sheet into the desired size and shape.
Step 2: Score the Kapton Polyimide Film with a sharp blade or a box cutter. Be sure to score only the Kapton Polyimide Film and not the copper layer.
Step 3: Apply a solvent such as acetone or isopropyl alcohol to the scored area. This will help to soften the adhesive that holds the Kapton Polyimide Film to the copper layer.
Step 4: Use a non-abrasive scrubbing pad or a toothbrush to gently scrub the scored area. This will help to loosen the adhesive and remove the Kapton Polyimide Film.
Step 5: Continue to apply the solvent and scrub until all the Kapton Polyimide Film is removed.
Step 6: Rinse the Pyralux Copper Sheet with clean water and dry it with a lint-free cloth.
In conclusion, removing the Kapton Polyimide Film from Pyralux Copper Sheets requires patience and precision. By following these steps, you can effectively remove the film without damaging the copper layer. Remember to use a proper solvent and scrubbing pad to ensure that the process is successful. With these tips in mind, you can now confidently etch your Pyralux Copper Sheets with ease.
