Close printed circuit board material and preparation method thereof.
Background technology
Printed circuit board (PCB) is the critical piece in electronic product, and its q＆r is heavy to closing for electronic product
Will.Epoxy prepreg (Epoxy Prepreg) is the main raw material(s) for producing printed circuit board (PCB) at present.Storage is aging will be to epoxy
The performance of prepreg produces significant impact, and then has influence on the quality of printed circuit board (PCB).And the wet-heat resisting of printed circuit board (PCB) is old
Change performance and directly influence the reliability of electronic product, characterize and improve its moisture-resistant heat aging performance have to electronics industry it is important
Meaning.Herein by various research meanses are combined, epoxy prepreg chemical and physical features in ageing process is stored are have studied
Change, so as to establish the aging quality supervision system of storage of epoxy prepreg, and be successfully applied to electronics industry.
By comparing the methods such as differential scanning calorimetry (DSC), middle infrared spectrum (Mid-IR) and near infrared spectrum (NIR), NIR is found
Can be very good to characterize the functional group's change before and after epoxy prepreg solidification.NIR results show 4530cm-1The epoxy peak at place and
4620cm-1Phenyl ring peak there is good resolution ratio and the overlap without other absworption peaks to disturb.Constant temperature at 100 DEG C of epoxy prepreg
The NIR tracking results of solidification show that keep uniform consumption in solidification process epoxide group, phenyl ring peak intensity is held essentially constant.
And then it is aging using NIR to have studied storage of the epoxy prepreg under different temperatures and humidity, find with storage temperature and aging
The increase of time, explanation NIR is accordingly increased to respect to curing degree aging to the storage of epoxy prepreg can be carried out effectively
Monitoring.Corresponding with solidification conversion ratio increase, the processing viscosity of epoxy prepreg is with storage aging temperature and the increase of time
Significantly improve, gel time accordingly shortens.Epoxy prepreg after dynamic mechanical analysis (DMA) discovery storage is aging occurs in that two
Individual glass transition temperature, binding time differentiates light scattering (TRSL) and the means such as petrographic microscope (OM), it was demonstrated that storage is always
Epoxy prepreg there occurs phase separation during change.Further improved by introducing amphipathic oligomeric silane coupling agent herein
The interface performance of resin and glass in printed circuit board (PCB), so as to improve reliability of the printed circuit board (PCB) in hygrothermal environment.Adopt
Synthesize a kind of amphipathic oligomeric silane coupling agent with silane coupler and octyl phenyl polyglycol ether, by gel chromatography
(GPC), the test specification such as IR, gas chromatography mass spectrometry chromatograph (GC-MS) its epoxy prepreg processing characteristics is not influenceed substantially.
The result of contact angle test shows that amphipathic coupling agent can significantly reduce contact angle of the resin to glass in epoxy prepreg.
Water absorption test finds, although the equilibrium water absorption of epoxy prepreg slightly rises after solidification, due to the work of amphipathic coupling agent
With the water suction of its interface is substantially suppressed.Circuit malfunction test, the test result of ESEM/energy disperse spectroscopy (SEM/EDX) are said
Bright, amphipathic oligomeric silane coupling agent can suppress the generation of conductive anodic filament (CAF) failure under hygrothermal environment, and then improve electricity
The reliability of road plate.In addition, compared with circuit malfunction is tested, interface water suction analysis can easily and effectively evaluate printed circuit board (PCB)
Resistance to CAF performances.
《Aging and printed circuit board (PCB) the hydrothermal aging research of storage of epoxy prepreg》The printed circuit board (PCB) that one text is obtained
Water resistance be improved, but epoxy resin property is more crisp, the caking property with glass surface is bad, by vibrations can peel off,
The stability in use of circuit board is influenceed, it is necessary to improve, in addition it is also necessary to improve the ageing resistance of circuit board.
