TECHNICAL DATA / PRINTED CIRCUIT BOARD FILM KODAK ACCUMAX Photoplotter Film ARD7 —High Complexity PCB Starts With the Right Phototools— July 2004 • TI-2574 Creating high-complexity phototools starts with the right film. Now from Kodak, you get hard-line-edge quality and superior dimensional stability with KODAK ACCUMAX Photoplotter Film ARD7. ARD7 Film uses the latest Integrated-Booster-Technology (IBT processing)— technology pioneered by Kodak. ARD7 Film is specifically designed for PCB phototool creation. Some of its outstanding features are: • Superior dimensional stability with Kodak’s exclusive one-sided gel coating structure—delivers low humidity coefficient of linear expansion of 0.0009% per % RH • Extremely sharp line-edge quality with the latest in Integrated-Booster-Technology processing (Recommended for processing in IBT compatible developers such as KODAK ACCUMAX Rapid Access Developer and Replenisher) Dimensionally stable support. 7-mil (0.18 mm) ESTAR Thick Base DARKROOM RECOMMENDATIONS Darkrooms can be illuminated using an EncapSulite T20⁄ND0.75 “cyan” filter. The light should be at least 4 feet (1.2 metres) from any area where the film will be handled. Where possible, the safelights should be located as to maximize room lighting for safety but minimize direct exposure to the film surface itself. The farther away the lights are located from the film, the greater the margin of safety. This filter should provide up to 4 minutes of acceptable safelight performance, under the stated conditions. • Coated on specially manufactured low-inclusion ESTAR support (0.007-inch, 0.18 mm) STORAGE AND HANDLING • Permanent anti-static performance to resist the attraction of dust and dirt Keep unexposed film and processed film in a cool, dry place. Process film as soon as possible after exposure. • Excellent scratch and abrasion resistant overcoat • Contains ultra-fine matte on the emulsion side to improve handling and vacuum draw-down to photo resist • Dual red sensitivity at 633 nm and 670 nm for use with photoplotters using helium-neon (HN) or red-laser-diode (RLD) exposing sources ARD7 Film is designed for the use with the following photoplotters: Manufacturer* Mania Barco Model BG-7300, BG-7400, BG-3800, BG-3900, BG-7500, SilverWriter Dainippon Screen RG 4000, RG 7000, RG 7500 * SUPPORT First EIE SA RP 24, RP 300, RP 500 Escher-Grad EG-5000, EG-8200, EG-9000, EG-9400 Mania Barco (Gerber) Crescent 30, Crescent 40 Glaser Galaxy 3000, Galaxy 4000, Galaxy 6000 Lavenir PULSAR 8000SE Orbotech LP 7008 Secma International Swift 2028, Swift 2636, Swift 3242, Swift 4257, Swift 4763 Products are trademarks of the respective manufacturer. ©Eastman Kodak Company, 2004 EXPOSURE PROCESSING The exposure required is a function of both the photoplotter characteristics and development conditions. Optimum exposure must be determined by means of a trial exposure series following the equipment manufacturer's recommended procedures. The calibration test will determine optimum exposure for required line width and D-max. The resulting image quality and D-max can be influenced by variations in time and temperature of development. Many customers may find that a change to the recommended time and temperature will provide a more suitable result for their particular exposing conditions. Notice: Observe precautionary information on product labels and on the Material Safety Data Sheets.

Multiply your current laser intensity setting by the factors as a starting point. An exposure sweep of over and under exposure is strongly recommended to determine optimum laser intensity. Please note the factors assume processing in the recommended developer and processing conditions as specified by the manufacturer.

RECIPROCITY With recommended processing, the reciprocity speed change is negligible (1⁄3-photographic stop or less) within exposure range of 1⁄1000 second to 1 billionth second, there is no change in contrast. 2 5L concentrate Time ACCUMAX Rapid Access Developer *Optimum 35°C (95°F)* 45 seconds* 38°C (100°F) 30 seconds 32°C (90°F) 60 seconds starting point recommendation for ACCUMAX Developer. Fixer: Use a starting temperature equal to or 1 to 2°C lower than the developer temperature. Replenishment Rates: Developer* Fixer† 465 mL / sq m 540 mL / sq m * Anti-oxidation replenishment rates should be set to achieve one tank turnover per week. † As a starting point, do not add hardener to the fixer. If abrasion or transport problems occur in processing, a small amount of KODAK Rapid Fixer, Part B can be added(CAT No. 173 3013, 72-ounce bottle). Start with 8 mL of Part B per litre of well mixed, working strength fixer, and increase as necessary to a maximum of 25 mL per litre. Add Part B slowly and mix thoroughly. Recommendations at Setup: ✔ Confirm processing time and temperature with calibrated stopwatch and digital thermometer. Adjust control settings to achieve the desired set points ✔ Measure replenishment rates with a graduated cylinder or beaker. Adjust replenishment settings to deliver required volume of developer and fixer for sheet size being used. KODAK ACCUMAX Photoplotter Film ARD7 • TI-2574 Dimensional stability is an all-inclusive term. In photography, it applies to size changes caused by changes in humidity and in temperature, and by processing and aging. The dimensional properties of ESTAR Base may vary slightly in different directions within a sheet; the differences that may exist, however, are not always equal in both the length and width directions. Differences in size change between length and width should be within 10 percent of each other.
