Technical field
The present invention relates to not contain the painted Photocurable resin composition of halogen-containing phthalocyanine green.Say in further detail, The present invention be more particularly directed to the disguised excellent solder mask that can provide the oxidation that utilizes copper circuit to cause variable color, the painted Photocurable resin composition that does not contain halogen-containing phthalocyanine green.
Background technology
Usually, solder resist forms in order to protect copper circuit.Its role is to, can't see by the variable color of the heat of copper circuit, variable color that moisture causes, electricity, such aspects such as flaw, pollution on the copper circuit.
Solder resist is applied on the glass epoxide base material that is formed with copper circuit, forms image through exposure, forms this overlay film pattern through development, heat curing.Owing on base material, be formed with copper circuit, therefore, under the situation to its coating solder resist or lamination solder resist, its resist film thickness is thick on the base material, thin on copper circuit, thinner in the part at the edge of copper circuit.
In the different situation of the thickness of such solder resist, be difficult to from covering copper circuit in appearance.Therefore, in solder resist, cooperate colorant usually, thicken, be difficult for variable color of seeing copper circuit etc. through making its concentration.
From reducing the viewpoint of carrying capacity of environment; Replace chlorination phthalocyanine green in the nearest solder resist as the colorant of existing green; Use the solder resist do not have the phthalocyanine blue of halogen atom and form green with the yellow colorants that does not have halogen atom to be popularized (for example, with reference to patent documentation 1).
In addition, for from clearly being halogen in appearance, can use phthalocyanine blue separately, also can be used as blue solder resist and use.
Yet; From following explanation; Can be clear and definite: compare with the green that forms by phthalocyanine green, the green solder resist that forms by solder resist, blue colorant and the yellow colorants of blueness disguised weak, less than the function of giving full play to as the colorant of the bad phenomenon that is difficult to see outward appearance.
Promptly, present solder resist is to form image, finally implement heat curing and handle through photocuring.The treatment temperature of this moment is generally 150 ℃ and descended about 30~60 minutes, but according to substrate manufacturer, temperature, time are fixing.Its result: under the situation that particularly treatment temperature is high, the processing time is long, there is the problem of the variable color that the oxidation of the copper circuit on can not hidden substrate causes in the solder resist of disguised bad blueness.Further confirm by the inventor, even use the blue colorant of halogen and the green solder resist of yellow colorants to have this problem too, a little less than phthalocyanine green disguise.
In addition, implementing on the substrate under the situation of marking ink, after the curing of solder resist, further typographic(al) mark and heat curing, so the variable color of copper circuit is quickened, apparent problem becomes more deep.
The warpage of the substrate that further produces when revising the heat curing of solder resist exists the substrate integral body situation with heat of exerting pressure, and this moment, the variable color of same copper circuit was quickened.
In the variable color of such copper circuit, the worst phenomenon is: though on identical copper circuit also only at the state of the edge of circuit (part of resist attenuation) variable color.Under such situation, when inspection, installation base plate, owing to do not calibrate with the inspection data, bad even non-defective unit also becomes.On the other hand, though see on the variable color copper circuit equably can with the situation of other parts identifications under do not produce such unfavorable condition.
Such condition of poor is former to be in the news, and particularly used replacing phthalocyanine green under the situation (colorant non-halogen) of the colorants such as phthalocyanine blue with halogen atom and became remarkable.
