Foil glass fiber laminate SF2-35 t.2.0 mm (300x200) double-sided 2GRADE
Double-sided, sheet thickness 2.0 mm, foil thickness 35 microns. Sheet size 300 mm x 200 mm (A4 format). From old stocks, produced in the 80s. Bargain, 2nd grade.
The depreciation of the cost (transfer to the 2nd grade) in this case is due to shallow surface oxides formed during long-term storage, as well as mechanical damage that occurred during transportation and cutting.
Such damage includes:
- blind scuffs, contamination and darkening of the foil (oxidation of the surface layer), requiring additional cleaning and grinding before use;
- separate through scratches and tears of the foil, no more than 10% of the total area;
- small manufacturing defects in the form of foil delamination 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.
Foiled glass fiber laminate of domestic production in the 80s.
Manufactured according to TU16-503.161-83.
Foil thickness 35 microns (real!).
Cutting to size 300 x 200 mm with an accuracy of ±2 mm (mostly plus).
Sheet glass fiber laminate, foil-clad with copper foil, grades STF-1-35 (single-sided foil, foil thickness 35 microns) and STF-2-35 (double-sided foil, foil thickness 35 microns) is used in instrumentation, radio engineering, electronics for the manufacture of printed circuit boards.
Allows mechanical processing.
Thickness 0.125-3.0 mm.
The time of resistance to the action of molten solder at t = 260 C is not less than 20 sec. (1 class). Peel strength in the initial state (for a strip width of 3 mm) not less than 4.5 N (class 1).
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).
