Halogen-free CEM-3 Epoxy resin copper-clad laminate using glass fabric and nonwoven glass fabric as base materials ■Features ●94V-O has been achieved without using halogen compound and antimony in the UL flame resistance test. ●Excellent in tracking resistance (CTI value: 600). ●Excellent in thickness accuracy. Variations in board thickness are ±0.05 mm. This thickness accuracy is equal to that of New CEM-3 R-1786. ●Excellent in high frequency characteristics. Small dissipation factor and thickness variations can realize designed performance. （Double-sided copper-clad） R-1586 （Single-sided copper-clad） R-1581 ●Provides dimensional stability equivalent to that of glass epoxy (FR-4). ●Reduces CO2 emission amount in our manufacturing process to one-quarter by means of our unique manufacturing process. (Compared with our conventional FR-4) ■Applications ●Liquid crystal television, PDP, PC peripheral equipment, air conditioner, plumbing equipment, power supply board, tuner, amusement machine, etc. ■Specifications（Assured values） Standard size (Warp × Fill) Thickness tolerance R-1586 Nominal thickness Warpage, Twist R-1581 Copper foil 0.018mm Copper foil 0.035mm Copper foil 0.018mm Copper foil 0.035mm 1.0mm Including 1.00±0.08mm 1.04±0.08mm 0.99±0.08mm 1.01±0.08mm copper foil 1.15±0.05mm 1.19±0.05mm 1.14±0.05mm 1.16±0.05mm 1.2mm ＋5 ＋3 1,220 ×1,020 mm −0 −0 1.6mm thickness. 1.52±0.05mm 1.56±0.05mm 1.51±0.05mm 1.53±0.05mm ＋5 ＋3 1,020 ×1,020 mm −0 −0 Single-sided Double-sided ≦9.0％ ≦7.0％ ≦6.0％ ≦2.5％ ≦2.5％ ≦2.0％ Note：When thickness is measured at 10 positions according to Section 5.3.3 in JIS C6481, thicknesses of at least 9 positions are within the tolerance range specified above.
