"Afternoon Tea": The first train technical talents for PCB industry school founded in Suining


PCB industry is the national "twelfth five-year" emerging strategic industries, high gold content technology, and technical skill talent gap more than 400000 people a year. Facing with the situation of skills talents shortage in suining, British creativity and thoughts of the school. In 2014, the state council issued "about speed up the development of modern vocational education decision", to "deepen the integration production and education, to encourage industry enterprises organize or participate in vocational education, give play to the role of enterprise important governance subject”. The open area at the same time vigorously called for a "public entrepreneurship, people’s innovation", more strengthened the faith that enterprise education. Earlier this year, the company has formed a "suining British chuangli printing technical vocational school" education plan, and get the support of municipal party committee, municipal government and the open area, the city bureau of education, city people club bureau with efficient service power enterprises."We have the confidence to the learned school-run me!"YiKeHua said.

The creativity of educational philosophy

On the concept of operations, the creativity and proposed "the CDB area economic development by service, service students' lifelong development, service PCB industry development for the purpose, committed to the development with international vision and international standard of PCB industry technical elite, the industry leader" of the training objectives, to build "the government, industry, enterprise, school, four one" training mode, the innovation "the school cooperation, JiaoJiao cooperation, cooperation, international cooperation between higher vocational colleges and the school-running idea, to create enterprise as" teaching management, teaching content, post production, project teaching method, teaching process and teaching information, teaching standard internationalization "school characteristics.

The creativity of education foundation

The creativity and the southwest university of science and technology, chengdu university of electronic science and technology and other institutions to carry out the cooperation between colleges and the talent training scheme between the two sides make joint the PCB industry, develop the school-based curriculum in the PCB production technology and participate in the teaching process. At present, the creativity and become students practice and high salary employment entrepreneurial base oral confession, three years has more than 500 people develop technical skills talents. Recently, the suining chuangli electronic technology co., LTD., is listed as one of the chengdu university of electronic science and technology postdoctoral workstation and PCB engineering experiment and scientific research achievements transformation base in Sichuan province.

About PCB service

1. Installation and welding of parts
the last step is the installation and welding the parts. Both THT and SMT parts use of machinery and equipment to install is placed on the PCB.
THT parts are usually called the Wave Soldering (Wave Soldering) way of welding. This allows all parts to a welding on the PCB.First to pin cut close to the board, and slightly bent so that parts can be fixed. Then the PCB will be moved to the co solvent on the waves of make contact to help at the bottom of the solvent, it can be on the base metal of the oxide to get rid of. After the heated PCB, the move to the melting of solder, at the bottom and contact after welding is completed.
Automatic welding of SMT parts way is called to flow back to welding (Over Reflow Soldering).Contains co solvent and solder paste in welding, the parts installed on the PCB after the first treatment time, was a PCB again after heating treatment. For PCB cooling after welding is completed, the next is to prepare the final test of PCB board.

2. Proofing
PCB's Chinese name is called printed circuit board, also known as printed circuit boards; printed circuit board is an important electronic component is electronic components support body? The provider of the electrical connection in the electronic components. Because it is made of so called electronic printing "printed circuit board.
PCB proofing is refers to the pilot production of printed circuit board before mass production is mainly used for electronic engineers in the design of circuit? And complete the PCB Layout to the factory after small batch trial-produce process is the PCB proofing. And PCB proofing production quantity generally no specific boundary is an engineer in product design has been finished to confirm and complete the test before we call it PCB proofing.
