Clean it with Isopropyl acohol until is free of any contaminant. Lamination: Remove the protectic layer with the help of two tapes. Apply the film over the copper clad and pass it through the laminator or iron. Try to avoid any wrinkles and bubbles between the film and the copper. Exposure: Laminar can be processed on conventional light sources. Exposure times: 5 - 15 minutes depending on light source. The exposure time depends on the light power. Expose the film until it becomes light blue, if the film is purple and brittle you exposed it too much and you will have problems during the developing process. Developing: Remove the second protectic layer. For one liter of water pour 15 grams of developer. Try to keep the solution between 28 - 30 degree celsius. With the help of a brush gently rub the sourface util the unexposed areas are removed. Rinse the board with water. Etching: for a strong etchant the compound is mixed in a ratio of 1 to 1 with water (e.g.1 kilogram Ferric Cloride + 1 liter water) more subtle works may be etched in a thinned solution of up to 1 to 4 ( e.g. 1 kilogram Ferric Cloride + 4 liter water) the ideal fast etching temperature is around 47 degree centigrade but works already at room temperature stainless steel requires a warmed etching bath the etchant should be in steady movement to prevent the slurry which is produced during etching to sink into the lines Removing(Stripping): For stripping the film you need a thinned solutionof 2 - 5% . Just put the copper for about 28 to 50 second and then rinse it with water. CAUTION: If you are using sodium Hidroxyde crystals be careful when pouring water, do it slowly and outside. The solution is going to create heat and release some fumes. Use gloves when handling the solution on the copper. These sheet is cut off from a roll Sent in Hard Tube or Envelope .
