Bungard Resin Bonded Paper Photo Resist PCB Bungard 120306E53, The original Bungard name represents the excellent quality and reliability of the materials and equipment used in producing circuit boards for prototypes and limited series production. The special quality requirement in case of photo coated base material can be measured with the following facts The base material conforms to all international standards and releases, as listed in summary in the standard IPC 4101 A. The photo lacquer is characterized by its detail rendering, sharp contrast and short processing times. However, particular attention should be drawn to its completely compliant characteristics in relation to processing tolerances. The only requirement is not to have the light exposure too short in order to have 'guaranteed' results. The lacquer coat is abolutely dust free with straight edges. The photo lacquer is burnt in and artificially aged, which ensures a very long storage time of over 1 year. A label indicates the use by date. When exposing and developing the advanced product quality is always clearly demonstrated by the relative colour changes. To distinguish them better, only original Bungard circuit boards have a special, blue dyed light protective film. Bungard 120306E53 FR4 Photo Resist PCB Single Sided 250mm x 250mm x 1.5mm
