As electronic devices to small, lightweight, multifunctional and environmentally-friendly direction, as the basis of a corresponding printed circuit board development in these directions, while the PCB is also the natural materials used to adapt these areas needs.
Environmentally friendly materials Environmentally friendly products for sustainable development, environmental protection requirements to use environmentally friendly materials, printed boards. The main material for the PCB copper clad board, in accordance with the European Union's RoHS-banned toxic polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) regulations, which relate to CCL brominated flame retardant cancel agent. At present, the international advanced countries have already adopted a large number of halogen-free CCL, while domestic non-halogen CCL products with foreign investment only in the successful development of large enterprises, many small and medium enterprises CCL still remain in the traditional CCL production, the ban can not adapt to environmental requirements.
Environmentally friendly products are not toxic but also required after the recyclable waste products. Therefore, the insulation resin layers PCB substrate considering the change from a thermosetting resin thermoplastic resin, it is easy to waste PCB recycling, after heating the resin and copper foil or metal parts separated from their recyclable. Foreign countries in this regard has been successfully used in lamination method developed high-density interconnect PCB's report, while domestic no movement. PCB solderability
surface coating materials, the most widely used is the traditional tin-lead alloy solder, now the European Union RoHS-banned lead substitute is tin, silver or nickel / gold plating. Electroplating chemicals abroad has in previous years on R & D to Electroless Nickel / Immersion Gold, chemical tin, silver plating drugs, and no domestic suppliers with a similar type of new material introduced.
Cleaner Production Materials Cleaner production is to achieve sustainable development, environmental protection an important means to achieve cleaner production needs of clean production auxiliary materials. PCB production is a traditional form of copper foil etching graphics minus method, the solution to consume the chemical corrosion, but also generate a lot of water. Foreign application has been developed and there is no copper catalyst type laminate material, the formation of direct chemical PTH Addition line graphics technology, which can eliminate corrosion, and reduce waste, help clean production. Process for the Addition of such a laminate material developed in the home or blank.
Cleaner and water solution without chemical cleaning of ink jet printing wire graphics technology, is a kind of dry production process. The key technology is the inkjet printer with the conductive paste material, abroad the successful development of nanoscale conductive paste material to make inkjet printing technology into practical application. This is the PCB revolutionary changes towards cleaner production. Cross country meet the PCB through hole line and use micron conductive paste material is also a lack of the nano-conductive paste material even a trace of.
In cleaner production also looking forward to gold cyanide plating process materials without harmful chemical formaldehyde as a reducing agent such as PTH craft materials, it is necessary to speed up and used for PCB production.
High-performance materials Electronic equipment to digital development, supporting the PCB and have higher performance requirements. Now facing a low dielectric constant, low moisture absorption, high temperature, high dimensional stability and so on request, to meet these requirements, the key is to use high-performance copper clad board material. Furthermore, in order to achieve thin PCB, high-density technology, needed thin fiber cloth, thin copper-clad board material. Flexible PCB
prominent light, thin, soft features, the key is flexible copper clad board material, a number of digital electronic devices require the application of high performance flexible copper clad board material. Flexible CCL currently improving the performance of direction is non-adhesive flexible copper clad board material.
IC package, PCB carrier board is a branch, now BGA, CSP, represented a new type of IC package by a large number of applications. IC package carrier board using high-frequency performance, heat resistance and dimensional stability of thin organic substrates. High-performance materials available in foreign applications, and further improvement to enhance and create new materials, compared to domestic counterparts in a number of high-performance materials is still in the blank.
To make printed circuit industry in China a great power with power, the urgent need for Chinese-made PCB materials. I am an expert from China Quality Digital, usually analyzes all kind of industries situation, such as organic yoga pants , cotton lycra pants.
