The Dynachem (formerly Rohm & Haas, Morton) Roll to Roll Exposure Unit EU 1530 RTR is an exclusive unit designed to directly expose the circuits from copper on both sides, direct light rolls. The masters alignment is obtained by means of pins and the exposing accuracy is assured by the punching initially made. The 5 kw lamps power, with optimized values of cooling and working conditions, together with the high concentration of
optical group, allow for a very high yield. It has an optional refrigerator unit with water intercooler. It provides a high light uniformity throughout the exposure area. The EU 1530 RTR allows high productivity and has an excellent exposure quality.
