Warning!
The depreciation of the cost (transfer to the 2nd grade) in this case is due to mechanical damage that occurred during transportation and cutting.
Such damage includes:
- blind scuffs, dirt and darkening of the foil (oxidation of the surface layer), requiring additional cleaning and grinding before use;
- individual through scratches and tears of the foil, no more than 10% of the total area;
- small manufacturing defects in the form of foil peeling along the edge of the sheet, surface irregularities;
- deviations of the geometric dimensions of the sheet over 5 mm, arising from cutting (cutting defects), not more than 10% of the nominal area of the sheet.
The main properties of fiberglass are not deteriorated.
Glass fiber laminate sheet, foil-clad with copper foil, brand DS-7408 (compliance with ANSI: FR4)
Key Features:
- tetrafunctional resin type;
- high glass transition temperature (Tg more than 1400С);
- excellent thermal stability;
- high chemical resistance;
- low water absorption;
Recommended areas of application - manufacture of printed circuit boards for computer technology, instrumentation, military industry, for control systems, etc.
UL Listed: E103670: IPC 4101
- low thermal magnification;
- UV blocking+AOI compatibility;
- increased dimensional stability;
FR4 glass fiber laminate is produced by one- and two-sided foil, foil thickness: 18 microns, 35 microns and 70 microns. Sheet thickness ranging from 0.05mm to 3.00mm.
Attention! Glass fiber laminate with dimensions larger than A4 (300 x 200 mm), in order to avoid damage during transportation by transport agencies, at least 2 pieces of the same sheet size are sent (thickness and foiling may be different).
