Izinto Zesekethe Ephrintiwe Ezivumelanayo |I-Polyimide Pcb |Ikhopha Pcb |Soldering Circuit Boards

Kulesi sihloko, sizobhekisisa izinto ezisetshenziswa kakhuluukukhiqizwa kwesekethe ephrintiwe eguquguqukayo.

I-Flexible printed circuits (FPC) ishintshe kakhulu inkambu ye-electronics.Ikhono labo lokugoba libenza badume ezimbonini ezehlukene ezihlanganisa i-aerospace, izimoto, ezokunakekelwa kwezempilo, kanye ne-electronics yabathengi.

Enye yezinto eziyinhloko ezisetshenziswa ekukhiqizeni amasekethe aphrintiwe aguquguqukayo yi-polyimide.I-Polyimide iyi-polymer esebenza kahle kakhulu enokuqina okuhle kakhulu kokushisa, ukumelana namakhemikhali kanye nokuqina kwemishini.Lezi zakhiwo ziyenza ilungele amasekhethi aguquguqukayo njengoba ikwazi ukumelana namazinga okushisa aphezulu kanye nezindawo ezinokhahlo ngaphandle kokuphazamisa ukusebenza kwayo.Amafilimu enziwe nge-polyimide avame ukusetshenziswa njengama-substrates amasekhethi aphrintiwe aguqukayo.

Ngaphezu kwe-polyimide, enye impahla evame ukusetshenziswa ekukhiqizeni isekethe ephrintiwe eguquguqukayo iyithusi.I-Copper yakhethwa ngenxa ye-conductivity yayo kagesi enhle kakhulu, ukumelana nokugqwala kanye ne-ductility.I-foil yethusi ezacile ngokuvamile i-laminated ku-polyimide substrate ukuze yakhe indlela yokuhambisa yesekethe.Isendlalelo sethusi sihlinzeka ngoxhumano lukagesi oludingekayo ukuze isekethe isebenze kahle.

Ukuze uvikele imikhondo yethusi futhi uqinisekise ubude besikhathi eside besifunda esiphrintiwe esiguquguqukayo, isendlalelo sekhava noma imaski ye-solder iyadingeka.Imbondela ifilimu enamathelayo ye-thermoset evamise ukusetshenziswa ezindaweni zesekethe.Isebenza njengesendlalelo esivikelayo, ivikela iminonjana yethusi ezicini zemvelo ezinjengomswakama, uthuli, nokulimala ngokomzimba.Isembozo ngokuvamile ifilimu esekelwe ku-polyimide, enamandla amakhulu okubopha futhi engaboshelwa ngokuqinile ku-polyimide substrate.

Ukuze kuthuthukiswe ukuqina nokusebenza kweziyingi eziphrintiwe eziguquguqukayo, izinto zokuqinisa ezifana netheyiphu noma izinto zokuqinisa zivame ukusetshenziswa.Engeza ukuqinisa ezindaweni ezithile zesekhethi lapho kudingeka khona amandla engeziwe noma ukuqina.Lezi zinto zingabandakanya izinhlobonhlobo zezinketho, njengefilimu ye-polyimide noma i-polyester, i-fiberglass, noma i-foil yensimbi.Ukuqinisa kusiza ukuvimbela amasekhethi ukuthi angadabuki noma aphuke ngesikhathi sokunyakaza noma ukusebenza.

Ngaphezu kwalokho, amaphedi noma othintana nabo bayengezwa ukuze kube lula ukuxhumana phakathi kwesekethe ephrintiwe eguquguqukayo nezinye izingxenye ze-elekthronikhi.Lawa maphedi ngokuvamile enziwa ngenhlanganisela yethusi nezinto ezikwazi ukumelana ne-solder.Amaphedi okubopha ahlinzeka ngokubonakalayo okudingekayo ukuze kuhlanganiswe noma kuxhume izingxenye ezifana namasekhethi ahlanganisiwe (ICs), ama-resistors, ama-capacitor, nezixhumi.

Ngaphezu kwalezi zinto ezingumongo ezingenhla, ezinye izinto zingaphinda zengezwe phakathi nenqubo yokukhiqiza kuye ngezidingo ezithile.Isibonelo, ama-adhesive angasetshenziswa ukuhlanganisa izingqimba ezihlukene zamasekethe aphrintiwe avumelanayo ndawonye.Lezi zinamathiselo ziqinisekisa isibopho esiqinile nesithembekile, okuvumela isifunda ukuthi sigcine ubuqotho baso besakhiwo.Izinamathiselo ze-silicone zivame ukusetshenziswa ngenxa yokuguquguquka kwazo, ukumelana nokushisa okuphezulu, kanye nezakhiwo ezinhle kakhulu zokubopha.

Sekukonke, izinto ezisetshenziswa ekukhiqizeni amasekethe aphrintiwe aguquguqukayo akhethwe ngokucophelela ukuze kuqinisekiswe ukusebenza okuhle nokuqina.Inhlanganisela ye-polyimide njenge-substrate, ithusi le-conductivity, imbondela yokuvikela, izinto zokuqinisa ukuze uthole amandla engeziwe, namaphedi okuxhumana kwezingxenye kudala umjikelezo ophrintiwe othembekile futhi osebenza ngokugcwele ovumelana nezimo.Ikhono lalawa masekhethi ukuzivumelanisa nezinhlelo zokusebenza ezihlukahlukene, okuhlanganisa izindawo ezigobile nezikhala eziqinile, liwenza abaluleke kakhulu emishinini yesimanje kagesi.

Kafushane, izinto eziguquguqukayo zesekethe eziphrintiwe ezifana ne-polyimide, ithusi, imbondela, iziqinisi, izinto zokunamathisela, namaphedi yizingxenye ezibalulekile ekudaleni amasekhethi e-elekthronikhi ahlala isikhathi eside futhi aguquguqukayo.Lezi zinto zisebenza ndawonye ukuze zinikeze uxhumano oludingekayo lukagesi, ukuvikelwa namandla okusebenza adingekayo emishinini yanamuhla kagesi.Njengoba ubuchwepheshe buqhubeka nokuvela, izinto ezisetshenziswa ekwenziweni kwesekethe ephrintiwe evumelana nezimo kungenzeka ziqhubeke nokuthuthuka, zinike amandla izinhlelo zokusebenza eziqanjiwe.
