Ingabe ama-PCB aqinile amelana nomswakama?

Uma kukhulunywa ngokumelana nomswakama nomswakama, umuntu angase azibuze ukuthi ama-PCB aqinile angahlangabezana yini nale nselelo. Kulokhu okuthunyelwe kwebhulogi, sizojula kulesi sihloko futhi sihlole ukumelana nomswakama nokuswakama kwama-PCB aguquguqukayo aqinile.
Amabhodi esekethe aphrintiwe (ama-PCB) awumongo wemishini kagesi yesimanje, ehlinzeka ngenkundla yokuxhuma nokusekela izingxenye ezahlukene ze-elekthronikhi. Ubuchwepheshe be-PCB buye bavela eminyakeni edlule, futhi enye yalezi ntuthuko kube ukwethulwa kwama-PCB aguquguqukayo aqinile.Lawa mabhodi anikeza ukuguquguquka okuhlangene nobuqotho besakhiwo samabhodi aqinile, okuwenza abe nezinto ezihlukahlukene kakhulu futhi afanelekele uhla olubanzi lwezinhlelo zokusebenza.

Umswakama kanye nomswakama yizici ezivamile zemvelo ezingathinta kakhulu ukusebenza nokuthembeka kwemishini kagesi.Ukuchayeka kumswakama kungase kubangele izinkinga ezihlukahlukene, okuhlanganisa ukugqwala, izikhindi zikagesi, kanye nokuwohloka kwe-insulation.Ngakho-ke, kubalulekile ukuqinisekisa ukuthi ama-PCB asetshenziswa kumadivayisi amelana nalezi zici, ikakhulukazi ezisetshenziswa lapho ukuchayeka kumswakama ophezulu kungenzeka.

I-Rigid-flex PCB inesakhiwo esiyingqayizivele futhi inezinga elithile lomswakama nokumelana nomswakama.Lawa mabhodi ngokuvamile enziwa ngenhlanganisela yezendlalelo ze-polyimide eziguquguqukayo nezendlalelo eziqinile ze-FR-4, okwenza ibhodi lesifunda eliqinile nelithembekile. Isendlalelo se-polyimide sinikeza ukuguquguquka, okuvumela i-PCB ukuthi igobe noma isonteke njengoba kudingeka, kuyilapho ungqimba lwe-FR-4 luhlinzeka ngokuzinza kwesakhiwo.

Esinye sezici eziyinhloko ekuthuthukiseni ukumelana kwama-PCB aqinile-flex kumswakama kanye nomswakama ukusetshenziswa kwe-polyimide njengesisekelo sezinto.Le ndawo ivikela ubuqotho be-PCB ngokuvimbela ungqimba lwe-polyimide ekumunceni umswakama.Ukwengeza, ukuguquguquka kwe-polyimide kuvumela amabhodi wesekethe ukuthi amelane nezimo ezithile zemvelo ngaphandle kokuthintwa umswakama.

Ngaphezu kwalokho, ibhodi eliqinile-le-flex likhiqizwa kusetshenziswa ubuchwepheshe obuthuthukisiwe ukuze kuthuthukiswe amandla ayo okuvikela umswakama kanye nomswakama.Lezi zinqubo zibandakanya ukusetshenziswa kwento evikelayo, efana ne-conformal coating noma i-sealant, esebenza njengesithiyo ekungeneni komswakama.Lezi zimbobo zenzelwe ukuvimbela umswakama ukuthi ungafinyeleli ezingxenyeni ze-elekthronikhi ezibucayi futhi ubangele umonakalo.

Kuyaphawuleka ukuthi nakuba ama-PCB aqinile-aguquguqukayo anomswakama obalulekile nokumelana nomswakama, awavikelekile ngokuphelele kulezi zici.Izimo ezeqisayo, ukuchayeka isikhathi eside kumswakama ophezulu, noma ukuphatha okungafanele kusengaphazamisa ukusebenza kwalawa mabhodi.Ngakho-ke, izidingo ezithile zemvelo zohlelo oluthile kufanele zicatshangelwe futhi i-PCB yakhelwe ngokufanele.

Lapho uklama ukumelana nomswakama wama-PCB aqinile-flex, izici ezimbalwa okufanele zicatshangelwe.Isikhala esanele phakathi kwezingxenye, ukubekwa uphawu okufanele kwezixhumi nama-vias, kanye nokusetshenziswa ngobuhlakani kwezinto ezivikela umswakama ezinye zezici ezibalulekile ezisiza ukwandisa ukumelana kwe-PCB kulezi zici zemvelo.Ukusebenza eduze nomkhiqizi we-PCB onolwazi kungaqinisekisa ukuthi umklamo uthuthukisiwe. ukufeza izinga elidingekayo lomswakama nokumelana nomswakama.

Ngamafuphi, ngenxa yesakhiwo sayo esiyingqayizivele kanye nokusetshenziswa kwezinto ezivikela umswakama njenge-polyimide, amabhodi aqinile-aguquguqukayo ngokuvamile anezindawo ezinhle zokuvikela umswakama kanye nomswakama.Bahlinzeka ngesixazululo esithembekile semishini kagesi engase ichayeke ezimweni ezinzima zemvelo. Nokho, kubalulekile ukucabangela izidingo ezithile zohlelo bese uklama i-PCB ngokufanele ukuze kwandiswe amandla ayo okumelana nomswakama kanye nomswakama. Ngokwenza lokhu, abakhiqizi bemishini ye-elekthronikhi bangaqinisekisa ukuphila isikhathi eside nokuthembeka kwemikhiqizo yabo, ngisho nasezindaweni ezinzima.
