These new size pre-sensitized PC boards using FR - 4 fiberglass substrate are in demand in many specialized applications. Like the standard series of 1/16" thickness, 1oz. Premier Printed Circuit boards, the new numbers may be exposed with any ordinary 100 watt light bulb.
Made of 1/16" thick FR-4 glass epoxy base with 1 oz. (0.0014") copper. Coated with positive etch resist photo sensitizer. Dielectric: 1 MHz = 5.3. These Premier Printed Circuit Boards may be exposed with an ordinary 100 watt incandescent light bulb.
2oz. boards have exactly twice the standard thickness of copper; a requirement in applications where higher current will be used or when higher conductivity is imperative. Made of 1/16" thick FR-4 glass epoxy base with 2 oz. (0.0028") copper. Coated with positive etch resist photo sensitizer. Dielectric: 1 MHz = 5.3.
