PTFE Thepi ya Mahiselo ya le Henhla ya FPC Hot Press Lamination Defect Defect

Tanihi muendli wa xiphurofexinali wa thepi ya mahiselo ya le henhla ya PTFE, Jiangsu Aokai New Materials yi ku nyika nhlamuselo leyi nga ni vuxokoxoko. Eka endlelo ra hot press lamination ya Flexible Printed Circuit Boards (FPC), PTFE high-temperature tape yi lulamisa swihoxo swimbirhi swa nkoka — substrate wrinkling na adhesive transfer — hiku tirhisa mbuyelo lowu hlanganisiweke wa swivumbeko swa swilo swa ntumbuluko (enerji yale hansi yale henhla, ku tshamiseka ka dimensional yale henhla) na tithekinoloji ta vukorhokeri lebyi antswisiweke (stacking structure design, parameter control). Yi tirha tani hi leyara ya kahle yo basa yo tihambanisa  na leyara ya buffer leyi ringanaka na ntshikelelo.

I. Swivangelo swa ku rhurhumela ka substrate na ku hundziseriwa ka swinamarheti

Substrate Wrinkling Rimitsu ra kona ri le ka ku hisa loku nga ringaniki na ku hangalaka ka ntshikelelo. FPC yi vumbiwa hi switirhisiwa swotala swofana na PI film, copper foil na swinamarheti leswingana ti coefficients tohambana hambana ta thermal expansion (CTE). Ku engetela kwalaho, swilo swa dizayini ya bodo ya xirhendzevutani ku katsa na ku enta ka koporo loku nga ringaniki na magoza ya stiffener swi ta endla leswaku ku va na ku hangalasiwa ka ntshikelelo loku nga ringaniki. Ku hisa na ntshikelelo leswinga faniki swi hlohletela ntshikelelo wa swilo swale ndzeni, leswi endlaka leswaku kuva na ku rhurhumela, ku soholota na ku delamination.

Adhesive Transfer (Residual Adhesive) Leswi swivangiwa ngopfu hi swihoxo swa interface na material. Semi-cured adhesive ya cover film ya lamination ya n’oka naswona yi khuluka ehansi ka mahiselo yale henhla, naswona yi namarhela ehenhla ka switirhisiwa swo tihambanisa. Hi nkarhi walowo, loko silicone pressure-sensitive adhesive leyi pfanganisiweke endzhaku ka PTFE tape yiri na ku tiya loku ringaneleke ka mahiselo kumbe ti parameters ta maendlelo letinga fambelaniki, ku tsandzeka ka cohesive kuta humelela eka mahiselo yale henhla, leswinga vanga ku hundziseriwa ka xiphemu xa adhesive eka vuandlalo bya FPC.

II. Tindlela ta Nkoka ta Thepi ya Mahiselo ya le Henhla ya PTFE ya ku Sivela Swihoxo

Ku Sivela Ku Pfuxetiwa ka Substrate

Ku hambanisiwa ka thermal shock & uniform pressure distribution Eka xivumbeko xa standard stacking: Hot plate → PTFE tape → silicone cushion → FPC → PTFE tape → Hot plate , PTFE tape yi tirha tani hi leyara yo humesa. Ku fambisa ka yona ka mahiselo loku tiyeke switiyisisa ku hundziseriwa ka kuhisa loku fanaka. Ku tirhisana na ti silicone buffer cushions, yi hunguta ntshikelelo lowu vangiwaka hi differential thermal expansion naswona yi ringanisela ntshikelelo hinkwawo, ku papalata ku hlangana ka ntshikelelo wa ndzhawu na ku rhurhumela loku landzelaka. Eka vuhumelerisi bya xiyimo xale henhla, thepi ya PTFE leyi tiyisisiweke hi glass-fiber leyingana CTE yale hansi ya hlohleteriwa eka kutshamiseka ka dimensional yale henhla.

Fasitere ra vukorhokeri bya ku hisa leri tiyeke Leyara ya PTFE yi sivela ku khumbeka ka mahiselo yo kongoma. Loko swihlanganisiwa na thermal hysteresis ya ti silicone cushions, ku fambisa kuhisa swiva swi olova naswona switshamisekile. Yi lawula ku hambana ka mahiselo ya interlayer endzeni ka ≤ 5~7 °C hinkarhi wa adhesive gelling, leswi endlaka leswaku ku humesiwa moya hiku hetiseka loko kungase tshamiseka ku horisiwa ka adhesive, naswona hi xisekelo yi herisa ku rhurhumela loku vangiwaka hiku gelling ka ha ri na nkarhi xikan’we naku hlwela ku humesiwa. Nhlayo ya ku hisa ya xiphemu lexikulu xa ku tlakuka ka mahiselo yi hlohleteriwa kuva yi lawuriwa eka 4.5~5.0 °C/min.

Ku herisiwa ka ku Hundziseriwa ka Swinamarheti

Nhundzu leyinga namarheliki leyingana ultra-low surface energy PTFE yina matimba yale hansi swinene yale henhla ( <18 mN/m), yale hansi swinene kutlula ya molten resin na swinamarheti. Hi matirhelo ya kahle swinene ya non-stick yofana na non-stick cookware, yinga tshoveriwa hiku olova endzhaku ka lamination handle ko khwaxa ti FPC substrates kumbe ku siya masalela ya glue.

Ku hlawuriwa ka sisiteme ya swinamarheti swa matirhelo ya le henhla Ku papalata ku hundziseriwa ka thepi hi yoxe hi yoxe, thepi ya PTFE leyi endliweke hi xinamarheti xa xiyimo xa le henhla lexi nga na ntshikelelo wa silicone yi ta amukeriwa. Premium silicone adhesive yi hlayisa matirhelo yo tiya eka kufika eka 260 °C, leswi tiyisisaka zero residual glue eka vuhumelerisi bya nkarhi woleha lebyi yaka emahlweni. Giredi ya ku tiya ka mahiselo yifanele ku fikelela swilaveko swa maendlelo hiku hetiseka (210–260 °C).

Ku horisa loku heleleke ka swinamarheti Hi nkarhi wa ku peta na ku humelerisa thepi ya Aokai PTFE, nkarhi wo horisa lowu nga fanelangiki, mahiselo kumbe rivilo ro tsutsuma swi ta endla leswaku ku horisiwa loku nga helelangiki ka namarheta, leswi yaka emahlweni swi vanga swiphiqo swa namarheta leswi saleke eka ku tirhisiwa loku landzelaka.

Leswi nga laha henhla swi nyikiwile hi Jiangsu Aokai New Material Technology Co., Ltd.

Loko u lava vuxokoxoko byo tala mayelana na swihlawulekisi swa swikumiwa, swiyimo swa xikombelo na swintshuxo leswi endleriweke layini ya hina ya swikumiwa leyi heleleke, ku katsa na lapi ra mahiselo ya le henhla ya PTFE, thepi ya mahiselo ya le henhla ya PTFE, bandi ra mesh ra mahiselo ya le henhla ya PTFE, bandi ra muchini wo fusa leri nga riki na swirhabyani, lapi leri funengetiweke hi PTFE leri nga na tlhelo rin’we, bandi ro fambisa leri nga tiyangiki eka mahiselo ya le henhla na lapi ra fibre ya nghilazi leri tiyiselaka mahiselo ya le henhla, hi kombela u ntshunxeka ku hi tihlanganisa:
