Embodiment Construction

[0078] The following comparative experiments show that the heterocyclic nitrogen and glycol swelling agent composition of the present invention adjusts the resin material to be textured with the etchant, so that a high affinity bond is formed between the resin and the deposited metal. In addition, this test shows that the heterocyclic nitrogen and glycol swelling agent composition of the present invention reduces the weight of the resin and is suitable for the decontamination process in the preparation of PWB.

[0079] The swelling agent of the present invention used is composed of 40% by volume of ethylene glycol monophenyl ether and 40% by volume of N-methyl-2-pyrrolidone (NMP), 10% by volume of ethylene glycol monophenyl ether and 20% by volume. % N-methyl-2-pyrrolidone (NMP), 20% by volume ethylene glycol monophenyl ether and 20% by volume N-methyl-2-pyrrolidone (NMP), 20% by volume ethylene glycol monophenyl It is composed of ether and 40% by volume of N-methyl-2-pyrrolidone ...

Abstract

The present invention relates to a swelling agent composition comprising a nitrogen heterocyclic compound and a diol and methods of using the composition. The swelling agent composition may also contain a high flash point solvent and water. The swelling agent composition is used to condition the resin material to etch a porous textured surface on the resin material. Porous texturing deposits metal on the resin material to form a high affinity bond between the textured resin material and the deposited metal. This bonding between metal and resin materials prevents delamination between metal and resin. The swelling agent combination of nitrogen heterocyclic compound and diol also removes resinous material stains from the substrate. Swelling agent compositions of azacycles and diols can be used to treat resinous materials used in the fabrication of printed wiring boards. Metal can be deposited on the textured resinous material by suitable plating methods.

Description

Technical field [0001] The present invention relates to a composition containing a nitrogen heterocyclic compound and a diol for use as a solventswell. The present invention specifically relates to a composition containing a nitrogen heterocyclic compound and a diol, and the composition is used as a swelling agent to adjust the resin material for porous texture, as well as to decontaminate and remove the resin material from the substrate. Background technique [0002] For many years, continuous metal coatings or patterned or discontinuous metal coatings or plating have been used to coat or plate non-conductive substrates in many industries and applications. This type of matrix is ​​usually a composite matrix, which is composed of a thin metal foil laminated or clad on both sides of a resin plate, so that a non-conductive plastic is sandwiched between two metal surfaces. Usually drill holes through the metal cladding and resin, and the resin is exposed at the hole. After the metal...
