Contents of this item:

1.10 sheets or 2 rolls of negative acting photoresist. (This is meaning UV exposed area of film will stay on the board). You will receive one of below 2 packaging style for the film:

(1)Packaging style of 10 sheets: Approx. 20cm L x 15cm W (7.87" L x 5.9" W) Per sheet.

(2) Packaging style of 2 rolls: Approx. 100cm L x 15cm W (39.3" L x 5.9" W) Per roll.

2. Developer. Approx. 12 grams in weight.

3. Resist Remover. Approx. 10 grams in weight.

Major Procedure of Making a Copper Photo Etched Plate FYI:

Step 1. Prepare works:

(1). You need to clean the both sides of cooper sheets. (0.2mm in thickness). With rubber scrubber and well wash & clean it.

(2). Precut the dry film. Please be reminded that the size of film should be a little larger than your plate. And also please note that doing this should be under a surrounding with subdued lighting to protect the film.

(3). Prepare the developer solution. The ratio of developer to water should be 1:80

(4). Prepare the resist remover solution. The ratio of resist remover to water should be 1:70

Step 2. Apply photoresist.

(1). This photoresist included 3 layers. The upper and bottom are clear protective layers.You need to remove one protective layer. Using a scotch tape can make this easier.

(2). Then you can apply the middle layer on your cooper plate. You can use a hot roll laminator or by hand if you do not have got that. But suggest you starting from one corner to the cross corner and remove all air bubbles between film and cooper plate.

(3). Do the same at the back side of cooper sheet. Then you have a cooper plate applied with photoresist on both sides. The photoresist on both sides with protective layer.

(4). Turn a electric iron upside down and set the temp. at 100? Place the copper plate on the top plate of iron for approx. 15 - 20 seconds. (Last too long will lead to over exposure effective)

Step 3: Exposure

(1). Align and fix your artworks in place by scotch tape. Then fill the cooper plate into the middle of your artworks.

(2). Use 2 pcs of glass on the up and bottom to press the artwork tightly to the board.

(3). Expose to UV-A light source (Fluorescent UV bug zapper light, Blacklight Blue, Fluorescent black light etc. ) Light source should be approx. 8 - 12" away from the cooper plate when exposing. Exposing time should be determined by the type of light. (5 minutes used in my this processing with 25W bulb)

Step 4. Develope(1) When completed exposing. Allowing rest for approx. 10 minutes. Then remove the protective photoresist layer with a small piece of tape.(2)Using a tweezer. Dip the plate into the developer solution prepared in step one. Observe the image of the resist. Pull it out from the solution when you find the image is clear. Hold it under running water and clean it. You'd better inspect it very carefully at this step.(The cooper plate can be always re-put into the developer solution when needed.)

Step 5. Etching the cooper plate / PCB

Step 6. Remove the resist

Dip the cooper plate into the remove resist solution prepared in the step one.

Some Tips for Buyers:(1). You'd better use the darkest setting of your printer. To make sure the dark areas in your negative artwork are completely black and can block any light.

(2). Wash & clean etching solution from your cooper plate completely when get well etched. To prevent over-etching.

(3). For beginners. It's a must to do some tests to accommodate the characteristic of the resists and build up some skill.

Hold it under running water and clean it. You'd better inspect it very carefully at this step.(The cooper plate can be always re-put into the developer solution when needed.)

Step 5. Etching the cooper plate / PCB

Step 6. Remove the resist

Dip the cooper plate into the remove resist solution prepared in the step one.
