Laminates for printed circuits using unidirectional glass fabric |
摘要 |
A description is provided of laminates for printed circuits using unidirectional glass fabric produced with continuous yarn which is twisted, has a low number of twists or zero twisting turns with different gramme weights, interlaced warpwise with a leno interwoven binding using glass yarns of 5.5 to 22 Tex at a spacing of up to 20 cm. The application of these laminates to the manufacture of printed circuits offers advantages in terms of surface roughness and waviness, dimensional stability, evenness and perforability.
