Developer for positive presensitized boards

To produce printed circuit boards and boards with the photo-positive method, etching agents, exposure equipment and a photo-positive developing agent are required. After exposing the circuit board, it is bathed in a special developing solution, making the circuit paths visible by removing the exposed photo-sensitive layer. Consequently, the board is ready for etching. All areas on the board not protected by the photo-sensitive layer are going to be removed by the etching agent during this step. Our shop offers photo-positive developing agents by BUNGARD. The developer comes in special aluminium-PE compound bags and intended for use in water at room temperature. The developing solution consists of a sodium-hydroxide solution, which comes in a bag with sufficient solution for one liter of water.
