Description
Technical field
The present invention relates to pcb board manufacture technology field, eight post lowering or hoisting gears of more particularly to a kind of screen process press.
Background technology
With the development of science and technology, printed circuit board (PCB) --- pcb board, is widely used in military project, communication, medical treatment, electricity
The high-technology field such as power, automobile, Industry Control, smart mobile phone, wearable.Pcb board, as important electronic unit, is electronics
The supporter of component.Because it is in the important function in electronic component field, therefore it is reputed as " electronics aircraft carrier " by many people.Cause
This, the production technology level of pcb board is increasingly becoming one important indicator of national science technical merit of measurement.
As countries in the world are in the IT industry of China's investment, the fast development of complete electronic set manufacture, countries in the world PCB enterprises
Also invested on a large scale in China in succession, PCB in China industry is from the eighties of last century middle and later periods eighties till now by more than 20
The fast development in year, experienced three development ranks with state-owned economy, Chinese-foreign joint venture and with foreign Sole Proprietorship as main flow
Section, has formed world-class scale, and yield, the output value have occupied world's first.
By the development of decades, PCB industries have turned into global big industry.In recent years, World PCB industry production value accounts for electricity
More than the 1/4 of the subcomponent industry gross output value, is the industry of proportion maximum in electronic component subdivision industry, occupies unique status.By
Need the printed circuit board that density is higher, performance is more stable in the electronic product of a new generation, PCB gradually to high density, it is highly integrated,
Fine rule road, small-bore, Large Copacity, lightening direction are developed, and technology content and complexity are improved constantly, and high accuracy prints set
The standby market demand will also be continuously increased.
It is high that the environment and resource problem and sustainable development of current PCB industries have been swung to unprecedented strategy
Degree.The development of PCB Industry in China must be strengthened administering, and be allowed to go on the recycling economy track of clean manufacturing, and PCB industries could be into
It is resource-conserving, environmentally friendly industry.Therefore, PCB enterprises must actively face this situation, accelerate to traditional PCB
Production carries out technological innovation and Industrial Revolution, really realizes energy-saving and emission-reduction, or even CR production.
Printed circuit board manufacturing processes customary is Copper Foil etching method, also referred to as subtractive process.It with copper-clad laminate is base that it is
Plate, line pattern against corrosion is formed through screen painting or photo-imaging, and circuit is obtained by chemical etching；If two-sided or multi-layer PCB
Hole metallization and plating are also carried out, realizes that interlayer circuit is interconnected.Therefore, PCB manufacturing processes complexity, operation are more, certainly will consume
Substantial amounts of water and electricity, can also consume many copper and chemical material, produce substantial amounts of waste water and pollutant.The development of electronic equipment
Trend is multi-functional, miniaturization, environment-friendly type and low cost, and this is its supporting PCB high density, lightening, ring with regard to corresponding requirements
Guarantor's type and low cost, traditional PCB technology and product obviously are difficult to reach requirement of new generation.Therefore American-European, Japan, South Korea and
The ground such as China Taiwan start to use silk-screen printing electronic circuit, also referred to as addition process instead.Addition process, is the increase needs on substrate
Layers of material, circuit is obtained by printing, it is no longer necessary to be etched, therefore will not produce the waste of material.Certainly, for silk screen
The requirement of printing machine also more and more higher.
