Nyob rau hauv high -} liaj teb kawg kev lag luam thiab cov hluav taws xob hluav taws xob uas yuav tsum muaj kev kub ntxhov ntau, thiab cov tshuaj lom neeg tsis kam,Polyimide Daim Kab Xevyog ib tug irreplaceable "Kub Txuj Ci". Qhov kev siab siab no {- kev ua yeeb yam kab xev, nrog nws cov duab sib xyaw ua ke ntawm ib puag ncig kev ua haujlwm ntawm Aerospace rau cov qauv siv hluav taws xob.
Polyimide daim kab xev yog ib daim kab xev tshwj xeeb ua los ntawm polyimide zaj duab xis raws li lub submate, thiab cov ntaub ntawv sib xyaw ua ke (xws li tso tawm daim ntawv lossis yeeb yaj kiab).
Cov yam ntxwv tseem ceeb thiab irreplaceable zoo ntawm polyimide daim kab xev
Huab tais - theem siab thiab qis ruaj khov:
Qhov no yog cov tseem ceeb ntawm polyimide daim kab xev, uas ua rau nws ua haujlwm ncaj qha nyob rau hauv cov chaw kub heev uas ib txwm muab tso tseg.
Cov hluav taws xob rwb thaiv tsev zoo nkauj:
Lub zog dielectric siab thiab muaj kev tiv thaiv zoo, uas yog qhov zoo tshaj plaws rau ib puag ncig lub siab thiab}{{12}} zaus} zaus hauv tshuab hluav taws xob.
Zoo heev lub zog thiab tawv:
Zaj duab xis substrate yog muaj zog, kua muag {{0} {Reawant, thiab khoov {{1} {{{1} {tsis kam, thiab tuaj yeem tiv taus hnyav ua thiab tuav.
Cov tshuaj zoo heev:
Resistant rau corrosion los ntawm feem ntau cov kuab tshuaj, cov roj, acids, thiab alkalis, tiv thaiv lub substrate kev puas tsuaj.
Cov nplaim hluav taws kub retardancy thiab cov pa luam yeeb tsawg thiab tsis - toxicity:
Polyimide nws tus kheej tsis yog - cov qauv hluav taws xob, xws li ulcl
Zoo heev tas qhov ruaj khov:
Tsawg thermal nthuav cov coefficient, muaj peev xwm tswj tau qhov xwm txheej tsis tshua muaj zog thaum qhov kub hloov pauv tau, kom ntseeg tau qhov tseeb ntawm precision sib dhos.
Tsawg outgassing:
Thaum siv nyob rau hauv lub tshuab nqus tsev lossis kaw lus kaw, nws yuav tsis tso cov roj loj kom muaj kuab paug rau ib puag ncig, sib ntsib lub siab kom huv ntawm aerospace thiab semiconductor raug.
MIT Application cov xwm txheej ntawm polyimide daim kab xev
Electronic thiab hluav taws xob Raug:
Cov ntawv luam tawm hluav taws xob (PCB) tsim: Tiv thaiv kev tiv thaiv thaum sib tsoo ntawm cov ntiv tes kub, cov chaw sib txuas, lossis thaj chaw tshwj xeeb. FPC (Saj zog Circuit Court board) Qhov Cuab Lub Zog, Lamination Muab.
Hlau siv hlau thiab lub rwb thaiv tsev chev: interlayer rwb thaiv tsev, xaus txhim kho, thiab bundling ntawm coils xws li motors xws li cov hloov pauv, thiab inductors. Rwb thaiv tsev kev tiv thaiv thiab qhia txog qhov siab- kub cable.
Cheebtsam hluav taws xob: kho, insulate, thiab tiv thaiv cua kub thiab capacitors encapsulation.
Muaj cov lag luam thiab kub ua kom sov:
Kev kub hnyav thiab cov hmoov txheej xim: tiv thaiv thaj chaw uas tsis tas yuav tsum tau cooated thiab walling - kub ci kub siab.
Kev rho tawm thiab kev tiv thaiv ntawm tshav kub tswm thiab cua sov nias txheej txheem.
Rwb thaiv tsev qhwv thiab kos cim ntawm siab - cov kav dej kub} kub.
Kev tiv thaiv ib ntus ntawm laser engraving thiab ntshav txiav.
Vaj Huam Sib Luag Semiconductor thiab Chaw Tsim Tshuaj Zaub Raug (FPD):
Kev txhim kho ib ntus, kev tiv thaiv, thiab cov kabmob thaum thaum muaj kev nyab xeeb.
Kev tiv thaiv cov txheej txheem kub kub hauv LCD / OLED tsim khoom.
Nqus Chamber ib puag ncig yuav tsum tau ua ultra -} siab huv thiab qis outgassing.
Lwm qhov chaw: kuaj cov cuab yeej kub siab, tsheb lub cav sib xyaw ua ke (qhia txog cov kev kub siab hais txog cov dej num).
Kev tsim kho thiab siv cov ntsiab lus
Deg Tu:
Xyuas kom meej tias saum npoo ntawm kev ua kom huv, qhuav, roj {{0} {{{free. Qhov no yog qhov yuav tsum tau ua ua ntej rau kev tau txais cov nyhuv zoo tshaj plaws.
Ambient kub:
Kev tsim kho qhov chaw tsim hluav taws xob yog pom zoo kom ua siab dua 15 degree. Tsawg tus kub yuav cuam tshuam txo cov ntawv nplaum thawj ntawm cov nplaum.
Yav dhau los txoj kev:
Tom qab tshem tawm cov ntawv tso tawm, thov kom yooj yim, thov nyiaj siab rau lub siab nrog daim ntawv txhuam lossis ntiv tes kom ntseeg tau tias cov ntaub ntawv sib chwv nrog lub substrate thiab zam kev ua npuas. Rau qhov ntswg repision, cov cuab yeej siv cov cuab yeej siv tau tuaj yeem siv.
Tshem tawm lub sijhawm (daim npog ntsej muag):
Nws yog feem ntau yooj yim dua thiab txo qhov kev pheej hmoo ntawm cov nplaum uas tseem tshuav tom qab daim kab xev tau txias mus rau chav sov. Ua raws li cov sij hawm tshem tawm lub rooj pom zoo los ntawm tus neeg xa khoom.
Kev nkag siab txog qhov kub tsis kam:
Them sai sai rau qhov sib txawv ntawm qhov kub tsis taus ntawm daim kab xev substrate thiab qhov ua tau zoo ntawm cov nplaum. Cov nplaum yuav swb lossis poob nws cov viscosity hauv qab lub decomposition kub ntawm lub substrate.
Cia:
Khaws rau hauv qhov chaw txias, qhuav (pom zoo kub: 15-25 degree, av noo<65%). Avoid direct sunlight.
