Bubuphi ubomi besekethe yePCB eguquguqukayo?

Intshayelelo

Kule post yebhlog, sijonge ukutyhila iimfihlo ezisemva kobomi bezi PCB zahlukileyo kwaye sikhanyisele ukuba zeziphi izinto eziphembelela ubomi babo obude.

Xa kufikwa kwibhodi yesekethe eprintiweyo (PCB) yehlabathi, enye yezona ntlobo zinomdla yi-PCB eqinile-eguqukayo. Ezi bhodi zidibanisa ukuguquguquka kwe-PCBs eguquguqukayo kunye nokuqina kwee-PCB eziqinileyo kwaye ziya zithandwa kakhulu kumashishini ahlukeneyo. Nangona kunjalo, omnye umbuzo ophakamayo ngulo: "Bude buphi ubomi beebhodi eziguquguqukayo?"

Ukuqonda iibhodi ze-rigid-flex

Ngaphambi kokuqonda ubomi benkonzo yeebhodi eziguquguqukayo, masiqale siqonde ukuba ziphi. I-Rigid-flex PCBs ziibhodi zesekethe ezenziwe ngeendawo eziqinileyo neziguquguqukayo ezenza uyilo olunemisebenzi emininzi. Oku kudityaniswa kokuqina kunye nokuguquguquka kufezekiswa ngokusetyenziswa kwezinto eziqinileyo kunye neziguquguqukayo ezifana ne-FR4 kunye ne-polyimide. Iibhodi eziguquguqukayo eziguquguqukayo zibonelela ngeenzuzo ezininzi, kubandakanya ukuncitshiswa kwexesha lendibano kunye neemfuno zendawo, ukuthembeka okuphuculweyo, kunye nokuqina okongeziweyo.

Izinto ezichaphazela ixesha lokuphila

Xa kuqwalaselwa ubomi benkonzo yeebhodi ezingqongqo-eziguqukayo, kukho izinto ezininzi eziza kudlala. Ngelixa ezi bhodi zenzelwe ukuhlala ixesha elide, iimeko ezithile zinokuchaphazela ubomi babo obude. Makhe sijonge ngakumbi kwezinye zezinto eziphambili ezichaphazela ubomi bebhodi eqinile:

1. Iimeko zokusebenza: Iimeko zokusebenza apho ibhodi e-rigid-flex ibonakaliswe inempembelelo enkulu kwinkonzo yayo. Izinto ezifana nobushushu, ukufuma kunye nokungcangcazela zonke zidlala indima. Amaqondo obushushu agqithisileyo okanye ukufuma okugqithisileyo kunokucinezela izinto, nto leyo enokukhokelela kwi-delamination okanye ukusilela kwangaphambi kwexesha. Ngokufanayo, ukungcangcazela okugqithisileyo kunokubangela ukukhathala kwindawo ye-flex, ekhokelela ekuqhekekeni okanye ukusilela kombane.

2. Ukukhethwa kwezinto: Izinto ezisetyenziswa kulwakhiwo lwe-PCB oluguquguqukayo ludlala indima ebalulekileyo ekumiseni ubomi bayo benkonzo. Izinto ezisemgangathweni ophezulu kunye neempawu ezibalaseleyo zoomatshini kunye ne-thermal ziyimfuneko ukuze kuqinisekiswe ukusebenza okuhlala ixesha elide. Ukukhetha izinto ezinokuchasana kakuhle nokushisa, iikhemikhali kunye nezinto zokusingqongileyo kunokunyusa kakhulu ukuqina kwebhodi.

3. Iingqwalasela zoyilo: Uyilo lweebhodi ezilukhuni-flex nazo zinefuthe elithe ngqo kwixesha labo lokuphila. Uyilo olufanelekileyo, ukucwangciswa kwe-stacking kunye nokubekwa kwecandelo kubalulekile ukuqinisekisa ukuhanjiswa koxinzelelo olulinganayo kunye nokunciphisa umngcipheko wokungaphumeleli. Uyilo olungafanelekanga okanye ukupakishwa okungalunganga kunokudala amanqaku oxinzelelo olungeyomfuneko akhokelela ekuthotyweni kwebhodi kwangaphambi kwexesha.

4. Inkqubo yokuvelisa: Inkqubo yokuvelisa ngokwayo iya kuchaphazela ubomi benkonzo yebhodi e-rigid-flex. Ukuchaneka kunye nokulawulwa kwekhwalithi ngexesha lenkqubo yokuvelisa, kubandakanywa ne-lamination efanelekileyo kunye nobuchule bokubambisana, kubaluleke kakhulu ukuphepha iziphene ezinokuphazamisa ingqibelelo yebhodi yesiphaluka. Ukongezelela, ukuphathwa ngokufanelekileyo kunye nokugcinwa ngexesha lokuvelisa kunye nokudibanisa kubalulekile ukukhusela nawuphi na umonakalo onokuchaphazela ubomi benkonzo.

Ukuqukumbela

Isishwankathelo, ubomi benkonzo yeebhodi ze-rigid-flex zichatshazelwa yizinto ezahlukeneyo, kubandakanywa iimeko zokusebenza, ukukhethwa kwezinto eziphathekayo, ukuqwalaselwa koyilo, kunye neenkqubo zokuvelisa. Ngokuqonda ezi zinto kwaye uzithathele ingqalelo ngexesha lokuyila kunye nezigaba zokuvelisa, ubomi benkonzo yeebhodi eziqinileyo ze-flex zinokulungiswa. Ukubambelela kwimigangatho yoshishino kunye nokusebenza kunye nomvelisi we-PCB onamava kunokuphucula kakhulu ukusebenza kwexesha elide kunye nokuthembeka kwezi bhodi ezinobuninzi. Ngoko ke, xa uqwalasela ubomi benkonzo yebhodi eqinile-eguqukayo, khumbula ukuba i-PCB eyilwe kakuhle, eyenziwe ngokufanelekileyo edityaniswe neemeko ezifanelekileyo zokusebenza inokunyusa kakhulu ukuqina kwayo kunye nexesha lokuphila ngokubanzi.
