Embodiment Construction
[0014] In order to be able to understand the technical means of the present invention more clearly and implement it according to the contents of the description, the specific embodiments of the present invention will be further described in detail below in conjunction with specific examples. The following examples are used to illustrate the present invention, but not to limit it scope of the invention.
[0015] Carry out the preparation of specific examples and comparative examples according to the formula described in specific examples and comparative examples in table 1 with the following method: accurately weigh polyquaternium salt, siloxane and polyolefin wax emulsion, and the above-mentioned weighed After each component is added into deionized water one by one, mechanical stirring is carried out at normal temperature until each component is uniformly dissolved in deionized water, and a steel plate release agent for PCB multilayer board lamination process is obtained. The ...

The invention discloses a steel plate release agent used in the lamination process of PCB multilayer boards. The release agent is in the form of pure liquid and consists of polyquaternium 1-7wt.% and siloxane 1.0-5.0wt.%. , Polyolefin wax emulsion 2‑10wt.% and the balance of deionized water are evenly mixed and prepared. When using, just soak the pressed steel plate in the release agent, take it out and dry it, and a layer can be formed on the surface of the steel plate Uniform solid release layer, which can effectively block the direct contact between the resin and the steel plate, has a good release effect, reduces the residue of resin particles, reduces the proportion of lamination depressions, and can improve the product yield of the lamination process; and the end of use Afterwards, it is convenient to remove by brushing and grinding, and no resin particles will remain. After filtering, the used waste liquid can be treated according to general waste water, and the environmental pollution is small.
Description
technical field [0001] The invention relates to a release agent, in particular to a steel plate release agent used in a PCB lamination process, and belongs to the technical field of additives for the PCB lamination process. Background technique [0002] The Chinese name of PCB (Printed Circuit Board) is a printed circuit board, also known as a printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. As the requirements for information transmission become higher and higher, the number of layers of PCB multilayer circuit boards is also increasing. The lamination involved in the production process of PCB multilayer boards is to use high temperature and high pressure to heat and melt the resin prepreg, make it flow, and then heat-cure it into a cured sheet, so that one or more inner layers are etched. Blackening or browning treatment) and copper foil are bonded into a ...
