China's PCB screen printing inks to achieve the

highest in the world

As the reform deepens and technological

development in China from a backward PCB

ink-producing countries jumped to become the

world's advanced countries, China's

PCB output value in 2003 in the world rankings,

the PCB industry has developed rapidly

leddevelopment of peripheral industries and

related industries. Whether the PCB with

high-grade cutting-edge equipment, instruments,

meters, or materials have rapid development, but

also jumped from a major importer into a major

exporter of equipment and materials technical

indicators have reached international standards,

especially PCB screen printing ink to the

world.

Historical Review and Application Status

The first one printed circuit board come out in

1959, around the early 1960s for mass

production. Initially as a mask for the

manufacture of printed circuit board graphics is

a heavy chromate colloidal sensitizer.

A photosensitive mask three stages of

development

(1) shellac photosensitive mask: This is the

oldest technology is the introduction of the

former Soviet Union, due to the complex process

of ethanol developer will soon be eliminated.

② glue photosensitive mask: this technology is

the process of plate and the system of signs

transplant, economical and practical.Later, the

technical staff led to the development of

physical solid membrane and chemical solid

membrane technology, soon to be promoted, but not

long storage at high temperatures.

③ polyvinyl alcohol photosensitive mask:

available for more than a month after such a mask

with a good, stable physical and chemical

properties than the glue mask made great progress.

Three mask to meet the growing market demand, in

view of the lines of the printed circuit board

graphics mostly in 1.5mm or more, there is an

urgent need for a new process instead.

(2) homemade screen printing resist ink

Mesh are silk mesh and mesh specifications less

plate method is the use of engraved red film and

etching patterns on reverse painting

method. Although the home-made screen

printing resist ink there are many inadequacies,

but it is also China's PCB manufacturing graphics

of a leap.

(3) Screen Printing commercialization of the

resist ink

Ink makers to see strong market opportunities of

the Chinese PCB ink, and soon launched a variety

of models, different performance screen printing

resist ink PCB ink market. Hong Kong, Japan, the

United States with the fastest speed of the

company's PCB screen printing resist ink to push

our country, and the establishment of a joint

venture company, brand ink stable performance,


5/13

easy to use, the most prominent feature is in the

process of faded ink has been greatly improved

- went to Mexico with the alkali-soluble,

eliminating the need for solvent cleaning and

solvent pollution. With the increase in the

board of TV panels and tape recorders, UV-curable

resist printing inks available, significantly

accelerated the rate of production of the PCB

board. 100% solid content of the ink solvent

evaporation is the material of choice in the

circuit board graphics processing quickly in one

to two years to the country, have sometimes

appeared to outstrip supply, ink manufacturers

to create unlimited business opportunities.

Optical imaging plating resist ink

With the expansion of the PCB material market,

a pattern plating method, also known as the

anti-plating method, plating resist ink was

introduced into China, the most prominent

advantages are: both as a general resist inks

acid in etching and in certain conditions


6/13

alkali etching can also be resistant plated

Cu-resistant plated with PbSn-resistant plating

of Sn-resistant plating NiAu, and resolution up

to 0.05mm/0.05mm line spacing / line width, as

precision circuit board processing to

create conditions.

It became one of the main material for making

graphics, medium and small enterprises do not

need special equipment, widely used in the PCB

industry, has now become the largest amount of

an ink in the PCB industry.

Second, the solder resist ink

Solder resist ink to permanently stay in

the

PCB surface protection circuit,

insulation, it can also protect the line to the

pad and the hole wall painted of Sn in the blowing

of Sn, the crest and stick welding disk into the

components welding.

The development of a solder resist ink

The surface coating of the printed circuit board

solder resist ink origin in the late 1960s,

China's PCB solder resist ink began in the late

1970s, start from import into the domestic, but

also heatset characters ink. By TV and tape

recorders, VCRs PCB heat limited conditions, the

UV curable solder resist ink have been

published. A few years later from the varieties

have increased: Bright, matte, Gyrosigma,

wrinkles type except in different colors for the

user to select.

Optical imaging solder mask

Thermosetting solder resist ink or UV solder

resist ink, the coating method is screen printing

graphics reveal the PCB pad. However, with the

printed circuit board graphics and pad lines line

spacing gradually thicken, and has been unable

to meet the requirements of the pump to screen

printing graphics. Solder dry film popular a

few years, but because the materials are

expensive, dedicated vacuum film manufacturing

technology is not widely available, the

complexity of the operation process, low yield,

now this technology has been eliminated. Today

suitable for high density PCB-ray imaging solder

resist ink, with thermosetting and UV solder

performance, the most prominent is its

resolution edge basic and optical imaging

plating resist ink quite.

(3) application and popularization of the

optical imaging solder mask ink

Although the scope of the solder resist ink

thermosetting solder resist inks and UV curable

ink application, but these are only for

single-sided and low-end electronic products,

PCB production in high-end printed circuit board

is also required optical imaging solder resist

ink. As the curtain coating technology


9/13

development, and a general increase of the

density of PCB line, optical imaging solder

mask ink to continue to use spreads to the medium

and small enterprises.

From the printed circuit board ink market,

optical imaging resist plating resist ink and

optical imaging solder mask ink is not only the

printed circuit board ink, it is the main

material in the high-precision printed circuit

board production.

, PCB ink Market Analysis

1.PCB ink prices continue to decline

With the rise of the PCB status of our country

in the world, the price of domestic PCB for

several years continuously decreased by 4-5

times, small and medium enterprises most

affected. PCB prices continued to fall, the

corresponding price reduction for the printing

of raw materials and auxiliary materials used,

and the price of basic and PCB dropped

considerable.

2 optical imaging of anti plating ink application

of universal

In view of optical imaging plating resist ink

prices are now significantly lower than the dry

film of about 2 to 3 times, and the utilization

of up to 95% or more, but without adding any

equipment and plant investment in recent years,

many manufacturers quickly Use a dry film

changed the use of optical imaging plating resist

ink. After a period of time, due to a

significant reduction in costs, shorten the

production cycle, many multilayer plant also use

this ink to complete the processing of the inner

plate and received satisfactory results. The

large dual-panel manufacturing plant also uses

a double-sided baking Road 滚涂 automatic line

production methods, the multiplier effect. So

far, the application of the ink basically

popularized the SMEs. With the internal

migration of PCB plant in Hong Kong and Taiwan,

some of the advanced coating methods such as:

spraying, electrostatic spraying, dipping into

the mainland of China, the plating resist ink of

the application and promotion of optical imaging

played an important large role in promoting.

(3) Screen Printing commercialization of the

Ink makers to see strong market opportunities of

the Chinese PCB ink, and soon launched a variety
