I-PTFE High-Temperature Tape ye-FPC I-Hot Press Lamination Defect Prevention

Njengomkhiqizi ochwepheshe we-PTFE itheyiphu yokushisa okuphezulu, i-Jiangsu Aokai New Materials ikunikeza incazelo enemininingwane. Enqubweni yokucindezela okushisayo ye-Flexible Printed Circuit Boards (FPC), itheyiphu ye-PTFE yokushisa ephezulu ikhuluma ngezinkinga ezimbili eziyinhloko - ukushwabana kwe-substrate nokudluliswa kwe-adhesive - ngemiphumela ehlanganisiwe yezakhiwo zezinto ezibonakalayo (amandla aphansi aphansi, ukuzinza okuphezulu kwe-dimensional) kanye nobuchwepheshe bokucubungula (isakhiwo sokupakisha, isilawuli sepharamitha). Isebenza njengesendlalelo esihle sokuhlukanisa esihlanzekile  kanye nesendlalelo sebhafa esilingana nokucindezela.

I. Izimbangela Zokushwabana Kwe-Substrate Nokudluliswa Kwezinto Ezinamathelayo

I-Substrate Wrinking Imbangela eyinhloko isekushiseni okungalingani nokusabalalisa kwengcindezi. I-FPC yakhiwe ngezinto eziningi ezifana nefilimu ye-PI, i-copper foil nama-adhesives anama-coefficients ahlukene we-thermal expansion (CTE). Ngaphezu kwalokho, izici zokuklama ibhodi lesifunda ezihlanganisa ukushuba kwethusi okungalingani kanye nezinyathelo eziqinile kuzoholela ekusabalaliseni kwengcindezi engalingani. Ukushisa okungajwayelekile kanye nengcindezi kudala ingcindezi yempahla yangaphakathi, okuholela ekushwabaneni, ukungqubuzana kanye ne-delamination.

I-Adhesive Transfer (I-Residual Adhesive) Lokhu kubangelwa ikakhulukazi isixhumi esibonakalayo kanye nokukhubazeka kwempahla. I-adhesive semi-cured of cover film for lamination iyancibilika futhi igeleze ngaphansi kwezinga lokushisa eliphezulu, futhi inamathela ebusweni bezinto zokuzihlukanisa. Khonamanjalo, uma ingcina yokunamathela ezwela ukucindezela kwe-silicone eboshwe ngemuva kwetheyiphu ye-PTFE inokumelana nezinga lokushisa okunganele noma imingcele yenqubo engafani, ukwehluleka kokubumbana kuzokwenzeka ezingeni lokushisa eliphezulu, okubangela ukudluliswa kwe-adhesive ingxenye endaweni ye-FPC.

II. Izindlela Eziyinhloko ze-PTFE High Temperature Tape Yokuvimbela Ukukhubazeka

Ukuvimbela Ukushwabana kwe-Substrate

Ukwehlukaniswa okushisayo okushisayo nokusabalalisa ingcindezi efanayo esakhiweni sokupakisha esijwayelekile: Ipuleti elishisayo → itheyiphu ye-PTFE → umcamelo we-silicone → FPC → itheyiphu ye-PTFE → Ipuleti elishisayo , itheyiphu ye-PTFE isebenza njengesendlalelo sokukhishwa. Ukushisa kwayo okuzinzile kuqinisekisa ukudluliswa kokushisa okufanayo. Ukusebenzisana ne-silicone buffer cushions, ikhulula ingcindezi ebangelwa ukunwebeka okushisayo okuhlukile futhi ibhalansisa ingcindezi iyonke, igwema ukugxila kwengcindezi yendawo kanye nokushwabana okulandelayo. Ngokukhiqiza okunembayo okuphezulu, itheyiphu ye-PTFE eqiniswe nge-glass-fiber ene-CTE ephansi iyanconywa ukuze kube nokuzinza okuphezulu kobukhulu.

Iwindi elizinzile lokucubungula okushisayo Isendlalelo se-PTFE sivimba umthelela oqondile wokushisa. Kuhlanganiswe ne-thermal hysteresis ye-silicone cushions, ukuqhutshwa kokushisa kuba mnene futhi kuzinzile. Ilawula umehluko wokushisa we-interlayer phakathi kuka-≤ 5~7 ℃ phakathi ne-adhesive gelling, ivumela ukudonsa komoya okuphelele ngaphambi kokwelapha okunamathelayo okungaguquki, futhi iqeda ngokuyisisekelo ukushwabana okubangelwa ukugeleza ngaphambi kwesikhathi kanye nokubambezeleka kokukhishwa kwegesi. Izinga lokushisa lesigaba esikhulu sokukhuphuka kwezinga lokushisa liyanconywa ukuthi lilawulwe ku-4.5~5.0 ℃/min.

Ukuqedwa kokudluliswa kwe-Adhesive

Isakhiwo esinganamatheli esinamandla angaphezulu aphansi kakhulu e-PTFE inezici zamandla angaphezulu aphansi kakhulu (＜18 mN/m), aphansi kakhulu kunalawo e-resin encibilikisiwe nezinamatheliso. Ngokusebenza okuhle okungekona okunamathelayo okufana ne-cookware engagxili, ingaxetshulwa kalula ngemva kokucwecwa ngaphandle kokuklwebha ama-substrates e-FPC noma ukushiya ingcina yeglue.

Ukukhethwa kwesistimu enamathelayo esebenza kahle kakhulu Ukuze ugweme ukudluliswa okunamathelayo kwetheyiphu, itheyiphu ye-PTFE eyakhiwe nge-adhesive ephezulu ye-silicone ezwela ukucindezela izokwamukelwa. Ingcina ye-silicone ye-Premium igcina ukusebenza okuzinzile kufikela ku-260 ℃, iqinisekisa i-glue eyiziro eyinsalela ekukhiqizeni okuqhubekayo kwesikhathi eside. Ibanga lokumelana nezinga lokushisa lizohlangabezana ngokugcwele nezidingo zenqubo (210–260 ℃).

Ukuphulukiswa Okuphelele Kwezinto Ezinamathelayo Ngesikhathi sokumbozwa nokukhiqizwa kwetheyiphu ye-Aokai PTFE, isikhathi sokuphulukisa esingafanele, izinga lokushisa noma isivinini sokugijima kuzoholela ekwelapheni okunamathelayo okungaphelele, okuphinde kubangele izinkinga zokunamathela ezinsalela ekusetshenzisweni okulandelayo.

Okuqukethwe okungenhla kunikezwa i-Jiangsu Aokai New Material Technology Co., Ltd.
