That is why, if you intend to try these as an alternative to water, that you wear latex gloves and carry out the technique under a fume extraction system of some sort. Watch. The 'resist' filmis self healing so It should never be noticed.Cut the long side of the film overhangto a fine point and fold it tightly back around and press itdown on the back of the board. The tissues samples are soaked for some hours in a series of graded ethanol solutions since ethanol and water are miscible. Now you need to heat up the film so it will attach to the copper layer. Briefly, this involves 'fixing' or embalming the tissue samples in formaldehyde solution.Then it is necessary to replace all the water in the tissues with paraffin wax so that the tissue is rigidly supported and it is therefore possible to cut 6 micron thick sections that can be stained and examined under a microscope. But a useful way to clean off any corrosion is to then soak the board in household ammonia. If your film was sent flat, the cardboard wrapping is marked with which is top and which is bottom. Once you are happy with the positioning of the film on your copper clad, lay it on a firm surface and use a roller to squeeze out as much water from between the copper and the film as possible. The photoresist is typically developed using a dilute Sodium or Potassium Carbonate solution. Exposure was over. Let it pull the board and film through by itself. 21 C $16.27.
