Ingakanani impilo yesekethe ye-PCB eguquguqukayo eqinile?

Isingeniso

Kulokhu okuthunyelwe kwebhulogi, sihlose ukudalula izimfihlo ezingemuva kwesikhathi sokuphila kwalawa ma-PCB ahlukile futhi sikhanyisele ukuthi yiziphi izici ezithonya ukuphila kwawo isikhathi eside.

Uma kukhulunywa ngebhodi lesifunda eliphrintiwe (PCB) emhlabeni, enye yezinhlobo ezithakazelisa kakhulu i-PCB eguquguqukayo eqinile. Lawa mabhodi ahlanganisa ukuguquguquka kwama-PCB aguquguqukayo nokuqina kwama-PCB aqinile futhi aya ngokuya aduma ezimbonini ezahlukahlukene. Nokho, umbuzo owodwa ophakamayo uthi: “Isikhathi eside kangakanani ukuphila kwamabhodi aqinile aguquguqukayo?”

Ukuqonda amabhodi e-rigid-flex

Ngaphambi kokuqonda impilo yesevisi yamabhodi e-rigid-flex, ake siqale siqonde ukuthi ayini. I-Rigid-flex PCBs amabhodi esekethe akhiwe izindawo eziqinile neziguquguqukayo ezivumela imiklamo esebenzayo. Le nhlanganisela yokuqina nokuvumelana nezimo itholakala ngokusetshenziswa kwezinto eziqinile neziguquguqukayo ezifana ne-FR4 ne-polyimide. Amabhodi e-Rigid-flex anikeza izinzuzo ezimbalwa, okuhlanganisa isikhathi esincishisiwe sokuhlanganisa kanye nezidingo zesikhala, ukwethembeka okuthuthukisiwe, nokuqina okuthuthukisiwe.

Izinto ezithinta ubude besikhathi sokuphila

Uma ucubungula impilo yesevisi yamabhodi aqinile-flex, izici ezimbalwa ziyavela. Nakuba la mabhodi eklanyelwe ukuthi ahlale isikhathi eside, izimo ezithile zingathinta ukuphila kwawo isikhathi eside. Ake sibhekisise ezinye zezinto ezibalulekile ezithinta impilo yebhodi eliguquguqukayo:

1. Izimo zokusebenza: Izimo zokusebenza lapho ibhodi le-rigid-flex livela khona linomthelela omkhulu empilweni yalo yesevisi. Izinto ezifana nezinga lokushisa, umswakama nokudlidliza konke kunendima. Amazinga okushisa aphakeme noma umswakama owedlulele ungagcizelela into, okungase kuholele ekutheni i-delamination noma ihluleke ngaphambi kwesikhathi. Ngokufanayo, ukudlidliza ngokweqile kungabangela ukukhathala endaweni eguquguqukayo, okuholela ekuqhekekeni noma ekuhlulekeni kukagesi.

2. Ukukhethwa Kwezinto: Izinto ezisetshenziswa ekwakhiweni kwe-PCB eqinile nezimo zidlala indima ebalulekile ekunqumeni impilo yayo yesevisi. Izinto ezisezingeni eliphezulu ezinezakhiwo ezinhle kakhulu zemishini nezokushisa zibalulekile ukuze kuqinisekiswe ukusebenza okuhlala isikhathi eside. Ukukhetha izinto ezinokumelana okuhle nokushisa, amakhemikhali kanye nezici zemvelo kungathuthukisa kakhulu ukuqina kwebhodi.

3. Ukucatshangelwa kwedizayini: Idizayini yamabhodi aqinile-flex futhi inomthelela oqondile esikhathini sawo sokuphila. Isakhiwo esifanele, ukuhlela ukunqwabelanisa kanye nokubekwa kwengxenye kubalulekile ukuze kuqinisekiswe ukusatshalaliswa kokucindezeleka okulinganiselwe kanye nokunciphisa ingozi yokwehluleka. Isakhiwo esingalungile noma ukunqwabelana okungalungile kungadala amaphuzu okucindezeleka okungadingekile aholela ekulimazeni kwebhodi ngaphambi kwesikhathi.

4. Inqubo yokukhiqiza: Inqubo yokukhiqiza ngokwayo izothinta impilo yesevisi yebhodi eliguquguqukayo eliqinile. Ukunemba kanye nokulawulwa kwekhwalithi phakathi nenqubo yokukhiqiza, okuhlanganisa namasu afanele we-lamination kanye ne-bonding, kubalulekile ukuze kugwenywe amaphutha angonakalisa ubuqotho bebhodi lesifunda. Ukwengeza, ukuphatha nokugcinwa okufanele ngesikhathi sokukhiqiza nokuhlanganisa nakho kubalulekile ukuvimbela noma yimuphi umonakalo ongathinta impilo yesevisi.

Isiphetho

Kafushane, impilo yesevisi yamabhodi e-rigid-flex ithintwa yizici ezihlukahlukene, okuhlanganisa izimo zokusebenza, ukukhethwa kwezinto ezibonakalayo, ukucatshangelwa kokuklama, nezinqubo zokukhiqiza. Ngokuqonda lezi zici futhi uzicabangele ngesikhathi sokuklama nezigaba zokukhiqiza, impilo yesevisi yamabhodi aqinile-flex ingathuthukiswa. Ukunamathela ezindinganisweni zomkhakha nokusebenza nomkhiqizi we-PCB onolwazi kungathuthukisa kakhulu ukusebenza okuhlala isikhathi eside nokuthembeka kwalawa mabhodi ahlukahlukene. Ngakho-ke, uma ucubungula impilo yesevisi yebhodi eliguquguqukayo eliqinile, khumbula ukuthi i-PCB eklanywe kahle, ekhiqizwe kahle ehlanganiswe nezimo zokusebenza ezilungile ingakhuphula kakhulu ukuqina kwayo kanye neminyaka yokuphila yonke.
