Label:Yes
2. Electroplating and Etching Support:Suitable for electroplating, hole covering and etching.
3. Effective Hole Covering Performance:Excellent ability to cover holes, high resolution.
4. Good Material Compatibility:Works effectively on various substrate materials commonly used in PCB fabrication, offering broad adaptability.
1. Versatile PCB Production Use:This dry film is widely used in PCB manufacturing, attach on the PCB surface to make it photosensitive.
5. Stable in Standard Plating Baths:Compatible with conventional plating solutions, maintaining surface integrity without wrinkling or discoloration during processing.
Specification:
Item Type: Photosensitive Dry Film
Applicable products: PCB board
Insulation material: Organic resin
Weight: Approx. 50g
Size: Approx. 1 * 0.3m / 3.3 * 1.0ft
Package List:
1 * Photosensitive Dry Film
Operating Steps:
1. Uncover the film, the photosensitive film is sandwiched between the two layers of film, first tear off one side, a little difficult to tear, try a few more
2. Then film, the copper plate can be slightly cleaned, flattened, try not to have bubbles
3. After the paste, the iron is slightly heated, not too hot, to fix
4. Print circuit board film, it is recommended to use film, you can achieve the highest fineness, if you do not require precision with tracing paper to print.
5. Exposure, put the printed pattern on the photosensitive plate, use ordinary energy-saving lamps for about 30 minutes, if there is an exposure machine for 1 minute, the sun has not been tried, it should be about 15 minutes, the exposure process is obvious, because the photosensitive The film changes color when exposed, and changes from light to dark blue. You will easily see your circuit diagram appear on the board.
6. Develop, peel off another protective film, put it into the developer (developer is 1:100 water, 10 grams of water, 1 liter of water), and use a cotton swab to wipe the board with a little force during development.
7. Etching, this needless to say etchant water saturated solution
8. After etching, take off the film, take off the film by 1:60 or 70, and soak the board for a few minutes.
