Benefits of technology

This patented technology provides stable compositions used with printed circuit board (PCB) materials such as laminates or epoxy resin coatings on their surfaces. These composites have improved resistance against heat damage caused by high temperatures compared to traditional soldering methods due to reduced thermal expansion mismatches. They also provide better electrical performance when connected electronics devices over longer periods without losing functionality. Overall, this new composition has enhanced durability while maintains its effectiveness at preventing cracks formed during manufacturing processes.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the quality control for producing high-quality PCBs while reducing their cost compared to traditional methods like screen casting or injection moldings.

Embodiment Construction

[0019] For the following, through the description of the examples, the specific implementation of the present invention, such as the manufacturing process involved, the operation and use method, etc., will be described in further detail, so as to help those skilled in the art to have a more complete concept of the invention and the technical solution of the present invention. , accurate and in-depth understanding.

[0020] It is known that the calcium-zinc stabilizer is the most used in the existing plate production, which belongs to the environment-friendly stabilizer, but different application fields have different requirements for the preparation process, preparation method and formula of the calcium-zinc stabilizer, so I want to It is impossible for those skilled in the field of stabilizers to use conventional, customary calcium-zinc stabilizers as stabilizers for the production of PCB substrates.

[0021] The current PCB board base material is mainly made of PTFE and phenoli

Abstract

The invention discloses a stabilizer for a PCB and a preparation method of the stabilizer. According to the invention, calcium-zinc salt is used as a matrix of the stabilizer, and soybean oil, activecalcium, an antioxidant, Q40 and YL-100 are added to modify the matrix, so the demolding and smoothness of the stabilizer matrix are improved; meanwhile, in order to improve the performance uniformityand stability of the prepared stabilizer, an adhesive and modified calcium-zinc stabilizer are added; on one hand, smooth demolding of the PCB matrix in the preparation process is achieved through the proportioning of all the components, and on the other hand, the stability of the stabilizer is improved through coordination and cooperation of the components. In the preparation process, conventional wet grinding is firstly adopted for preparation; but different from the prior art, after liquid is completely evaporated, constant-temperature standing is adopted for aging treatment on the stabilizer, and the aging treatment is mainly used for improving the mechanical properties of the stabilizer, so when the stabilizer is used, the mechanical properties of the matrix is improved.
