Abstract
In accordance with the present invention, compositions are described which are useful, for example, for the preparation of metal-clad laminate structures, methods for the preparation thereof, and various uses therefor. Invention metal-clad laminate structures are useful, for example, in the multi-layer board (MLB) industry, in the preparation of burn-in test boards and high reliability boards, in applications where low coefficient of thermal expansion (CTE) is beneficial, in the preparation of boards used in down-hole drilling, and the like.
Claims31
A laminate comprising:
- at least one low loss dielectric layer formed from a composition comprising:
- a first resin that forms a triazine structure upon curing,
- a second resin comprising a polyphenylene oxide,
- a substantially halogen-free, phosphorus-containing flame retardant having an atomic phosphorus content in the range of about 1-20 weight percent, based on the total weight of the resin components, and
- a quantity of a particulate filler, the particulate filler being present in a range of about 50 to about 400 parts by weight based on 100 parts by weight of the first resin and the second resin.
A resin coated electrical component comprising:
- a substrate,
- a coating formed on the substrate, the coating being formed from a composition comprising:
- a first resin that forms a triazine structure upon curing,
- a second resin comprising a polyphenylene oxide,
- a substantially halogen-free, phosphorus-containing flame retardant having an atomic phosphorus content in the range of about 1-20 weight percent, based on the total weight of the resin components, and
- a quantity of a particulate filler, the particulate filler being present in a range of about 50 to about 400 parts by weight based on 100 parts by weight of the first resin and the second resin.
A method of making a laminate comprising:
- forming a low loss dielectric layer from a composition comprising:
- a first resin that forms a triazine structure upon curing,
- a second resin comprising a polyphenylene oxide,
- a substantially halogen-free, phosphorus-containing flame retardant having an atomic phosphorus content in the range of about 1-20 weight percent, based on the total weight of the resin components, and
- a quantity of a particulate filler, the particulate filler being present in a range of about 50 to about 400 parts by weight based on 100 parts by weight of the first resin and the second resin, and
- curing the low loss dielectric layer.
