Imbangela nokuwa kunqunywa izici ezibonakalayo. Ukuze kuxazululwe le nkinga ye-ukuncipha kwe- Ngesandla Esiqinile-Nezimo PCB IBhodi , ake isingeniso esifushane ukuze indaba of the nezimo ipuleti Polyimide:
(1) polyimide ine omuhle kakhulu ukusebenza ezishisayo, ungakwazi ukumelana ukushaqeka ezishisayo lomthofu-free ukuphathwa nokunamathisela ngomthofu ukushisa;
(2) kumadivayisi Iningi abakhiqizi bavame ukusebenzisa nezimo izifunda ibhodi amadivayisi ezincane ezidinga ukugcizelela isignali ubuqotho;
(3) Polyimide has a lokushisa ingilazi okusezingeni eliphezulu inguquko kanye okusezingeni eliphezulu ukuma izici,
kwezimo ezivamile ukuba kusetshenzwe ngaso 350 ℃ noma ngaphezulu;
(4) Ngo-nokonakala organic, polyimide kuyinto zingaxazululeki kumakhemikhali awuketshezi ezivamile eziphilayo.
Nezimo ipuleti impahla phezulu naphansi ne main PI base impahla kanye glue unobuhlobo, okungukuthi, ubuhlobo okukhulu ne imidation ka PI, ayanda degree of imidization, ukuya ngokuqina controllability.
Ngokusho imithetho evamile ukukhiqizwa, ngemva nezimo ibhodi ahlabayo, futhi ukwakheka ihluzo umugqa, futhi inhlanganisela yalokhu eqinile ezithambile e inqubo kokucindezelwa kuyodingeka ntshashintshe wokukhula kumthamo ihluzo umugqa etching, umfutho umugqa nesiqondiso , Ingabe eziholela reorientation yokucindezeleka salo lonke ebhodini, futhi ekugcineni kungaholela ukulawulwa jikelele ibhodi phezulu naphansi izinguquko; e inqubo ngokuhlanganisa soft futhi kanzima, njengoba ebusweni esehlanganise ifilimu futhi base impahla PI ukunwetshwa Coefficient engahambisani, Phakathi kwenkululeko ngezinga elithile ukunwetshwa.
Kusukela isizathu nemvelo, noma yikuphi ukwenyuka impahla kanye kuthintwa lokushisa futhi, ngenxa eside PCB ukukhiqizwa inqubo, impahla emva ashisayo inqubo eziningi ezimanzi, ephakeme ukubaluleka ukuncipha ungaba ngamazinga ahlukene izinguquko ezicashile, kodwa esikhathini eside langempela ukukhiqizwa isipiliyoni, ushintsho noma avamile.
Indlela yokulawula kanye ngcono?
Empeleni, ukucindezeleka sangaphakathi umqulu impahla ngayinye ihlukile, futhi control inqubo batch izingqimba ngamunye ngeke ifane patsi. Ngakho-ke, kokulawulwa Coefficient ukunwetshwa impahla kusekelwe inombolo enkulu lezisekelo zokuhlola On the control inqubo kanye nedatha ukuhlaziya ngokwezibalo kubaluleke ngokukhethekile. Ngo ukusebenza langempela, i-ukuncipha plate nezimo uhlukaniswe izigaba:
I wokuqala uvela ukuvulwa kuya bhaka, Lesi sigaba ngokuyinhloko kubangelwa lokushisa imiphumela:
Ukuqinisekisa ukuthi ipuleti baking okubangelwa nokuwa ukuzinza, owokuqala ukucubungula ukulawula ukungaguquguquki, ngaphansi kwesisekelo elinama enobunye, ngamunye baking ipuleti Ukushisa lwaluyophola imisebenzi kumele kuhambisane, singavele nje siphishekele kahle, wafaka kokuqendwa amapuleti emoyeni ukushabalalisa ukushisa. Okuwukuphela kwendlela ukunciphisa ukucindezeleka yangaphakathi kubangelwa ukunwebeka impahla nokuncipha.
I yesibili isigaba ezenzeka esikhathini inqubo yokudlulisa iphethini. I ukuncipha zalesi sigaba ngokuyinhloko kubangelwa ushintsho ukucindezeleka kwesibuko impahla.
Ukuqinisekisa ukuthi inqubo yokudlulisa umugqa uqinile, Wonke amashidi baking alikwazanga igedle, ngqo ngokusebenzisa amakhemikhali yokuhlanza umugqa ebusweni oyi-ukwelashwa, ngemuva kwengcindezi ulwelwesi ebusweni kumele wazi off, ibhodi ebusweni ukuma ngaphambi nangemva kwesikhathi ukuchayeka kumelwe lizwakale ngokwanele , emva kokudlulisela entanjeni, ngenxa ushintsho orientation ukucindezeleka, ipuleti nezimo uyodala degree ezahlukene crimp nokuncipha, ngaleyo ndlela ifilimu isinxephezelo ubuhlobo ukulawula lozalo onzima ezithambile lihambisana ngokunemba lokulawula, ngesikhathi ngesikhathi esifanayo, nezimo ipuleti uyanda futhi uya ngokuya ascertainment we ububanzi bamanani, kukhiqizwe yayo ukusekela panel eqinile nakho ngeke kusize idatha isisekelo.
I wesithathu esigabeni se-ukusikwa kwenzeka inqubo onzima ezithambile ibhodi cindezela, main kokucindezelwa imingcele futhi izakhiwo impahla zalesi sigaba bazimisele.
Ingabe Zikhona Izimo Ezenza ezinomthelela nalesikhathi sokuphela ukunwetshwa zihlanganisa Ukushisa ngesilinganiso yokuvikela ngocwazi, ukushona ingcindezi imingcele, kanye asalile zethusi izinga kanye ukushuba ekujuleni kwenhliziyo. Ngokuvamile, ezincane asalile izinga ithusi, mkhulu ukubaluleka ukuncipha; the ohlabayo nengaphakathi enkulu ukubaluleka nokuwa. Nokho, kusukela enkulu amancane kuyinqubo eyenzeka kancane kancane, ngakho ifilimu isinxephezelo kubaluleke ngokukhethekile. Ngaphezu kwalokho, ngenxa yesimo of the ibhodi nezimo futhi ibhodi eqinile nakho ngeke kusize impahla, isinxephezelo yayo kuyisici ezengeziwe kumele kucatshangwe.
