DURAVER(r)-E-Cu quality 156
DURAVER(r)-E-Cu quality 156 ML
DURAVER(r)-E quality 156 ML
DURAVER(r)-E-Cu quality 156 is a base material of type FR-4. The resin matrix is based on a phosphorus-modified epoxy resin; conventional E-glass-fabric is used for reinforcement. The requirements of flammability class V-0 as per UL 94 are met without addition of antimony compounds.
Since this grade does not contain halogens, it displays greater thermal stability than a standard FR-4, as T-260 measurements prove (Time to Delamination).
Laminate constructions
The same types of E-glass-fabric is used for DURAVER(r)-E-Cu quality 156 as for our DURAVER(r)-E-Cu quality 104 (FR-4).
In the case of thin multilayer laminates with copper claddings of 18 u, 35 u and 70 u we always use HTE foil with temperature resistant treatment.
Supply Forms
The laminates are produced in sheet size 1225 mm x 1070 mm (warp).
Prepregs are offered in roll width approx. 1255 mm.
Other sheet sizes and roll widths on request.
Laminate and prepreg panels are cut to specifications.
The prepregs' shelf life of three months at 22 degrees C and a relative humidity of 50% can be extended considerably by cold storage. Condensation must be avoided when removed from the cold storage.
Processing
When pressing this product grade, it should be allowed to cure for 90 minutes at a temperature of about 200 degrees C. The laminate will then be fully cured and no additional postbaking is required. The required pressure is 200 N/cm2 for a size of 300 mm x 500 mm.
