摘要 |
<p>Printed circuit boards of a laminate having surface layers of curable resin impregnated woven glass fabric and intermediate layers of curable resin impregnated non-woven glass. The intermediate layers contain 200 percent by weight to 275 percent by weight, based on the resin in the intermediate layers, of a thermally stable aluminum hydroxide of the molecular formula Al<SUB>2</SUB>O<SUB>3</SUB>.nH<SUB>2</SUB>O, wherein n has a value of 2.6<n<2.9. The aluminum hydroxide has a specific surface area, measured by the BET method, of 2 to 10 m<SUP>2</SUP>/g and a particle size in the D50% range of 5 to 10 mum.</p> |
