Izinzuzo kanye nezicelo ze-Semi-Flex PCB Technology

Ama-PCB abalulekile ekusebenzeni kwezinto zikagesi zesimanje, anika amandla imiklamo yesekethe eyinkimbinkimbi kuyo yonke inqwaba yamadivayisi kusukela kuma-smartphones kuya kumasistimu omkhathi. Ngenkathi ama-PCB ajwayelekile aqinile ebusa imakethe ngokuthembeka kwawo, kunesidingo esikhulayo sokuguquguquka kwezinye izinhlelo zokusebenza. Lesi sidingo siqhubekisele phambili ukuvela kwe-semi-flex PCBs, okwenza kube nokulinganisela phakathi kwemiklamo eqinile neguquguqukayo ukuze ihlangabezane nezidingo zobuchwepheshe ezihlukahlukene.

Ukuqonda ama-Semi-Flex PCBs

Ama-PCB aguquguqukayo, njengoba igama lisho, ahlinzeka ngokuguquguquka okuncane kanye nokuqina okuyingxenye. Angakwazi ukugoba futhi agobe ngezinga elithile, ngokuvamile phakathi kuka-30 kuya ku-130 degrees, kodwa awakwazi ukugoba okuphindaphindiwe njengama-PCB aguquguqukayo ahlanzekile. Lokhu kuguquguquka okuncane kuvumela ukunyakaza okuthile nokudlidliza emkhiqizweni wokugcina kuyilapho kugcinwa ukuqina kwesakhiwo sonke.

I-Semi-flexible PCB Materials kanye nezakhiwo

Ama-PCB athambile kancane enziwa ngezinto ze-FR-4 , okwenza abe yindlela engcono kakhulu kune-PCB ezithambile. Izingqimba zomqhubi zakhiwa ngokufaka ama-foil ethusi, ngokuvamile angama-ounce angu-35 (1μm) ubukhulu, ku-substrate. Ama-foil ethusi aqoshiwe noma afakwe ngogesi avame ukusetshenziswa. Isendlalelo semaski esithambile sisetshenziswa phezulu ukuchaza izindawo zokunamathisela nokuvimbela ukubopha. Izingxenye eziqinile ze-PCB zisebenzisa imaski evamile yokunamathisela eluhlaza.

Lawa ma-PCB angahlanganisa izendlalelo ezi-2 kuya kweziyi-8 eziqhubayo, okuvumela umzila wesekethe oyinkimbinkimbi ofana nama-PCB aqinile anezingqimba eziningi. Ama-Vias nama-vias agqitshwe angaxhuma phakathi kwezingqimba, futhi ama-component pads kanye nama-trace asebenzisa ukuqeda okujwayelekile kwethusi noma kwe-solder njenge-Immersion Tin, i-ENIG , noma i-OSP.

Izinzuzo kanye nezicelo ze-Semi-Flex PCBs

I-semi-flex PCB ingagoba kuphela ezindaweni ezithile eziklanyelwe ukugoba, iqinisekise ukuthi igoba kuphela ngezindlela ezinqunywe kusengaphambili nasemaphoyinti achaziwe. Ngaphandle kwezindawo eziguqukayo, i-semi-flex PCB ihlala iqinile, ifana ne-PCB yendabuko eqinile. Lokhu kufinyelelwa ngenqubo yokukhiqiza ehilela ukujula okulawulwayo kokulawulwayo noma ukugaya okokusebenza kwe-FR4 ku-PCB kuze kube mncane kakhulu futhi kuguquguquke. Ingxenye eguquguqukayo ibe iphathwa ukuvimbela ukuqhekeka, ukuyivumela ukuba igobe ngokukhululeka. Ama-PCB ama-Semi-flex nawo akhiqizwa kusetshenziswa ama-laminates amaphakathi amancane, anama-laminates azacile njengo-0.005 mil asetshenziselwa izinhlelo zokusebenza eziguquguqukayo. Ama-foil ethusi agayiwe (i-RA) ayanconywa ukuvimbela ukuqhekeka futhi anike amandla ukuguquguquka okuqine kakhudlwana.

Ama-Semi-flex PCB alungele izimo lapho i-PCB idinga ukugotshwa kuphela ukuze ifakwe kanye nokulungiswa okuzayo okungaba khona. Imvelo yabo eguquguqukayo futhi ibenza babe ukukhetha okufanelekile komklamo wezinhlelo zokusebenza lapho isikhala sicatshangelwa ngokubalulekile. Izinhlelo zokusebenza ezijwayelekile zama-semi-flex PCB zifaka ezezimoto, izisetshenziswa zezimboni, nokuphepha kukagesi, okubonisa ukuguquguquka kwazo nokuthembeka.

I-Semi-Flex PCB Ukuqhathanisa nezinye Izinhlobo ze-PCB

Ama-PCB Aqinile : Lawa ma-PCB akhiwe ngokuphelele ngezinto eziqinile ze-FR4, awanikeli ikhono lokugoba. Ngokuphambene nalokho, ama-PCB athambile anezindawo ezigobayo, okwenza kube lula ukugoba okulawulwayo ngezinga elithile.

Ama-Flex PCB : Uma kusetshenziswa amafilimu epulasitiki amancane njenge-polyimide, ama-flex PCB aguquguquka ngokuphelele futhi ayagobeka kodwa awanamatheli kahle. Ama-Flex PCB aguquguquka kancane, ngakolunye uhlangothi, afinyelela ibhalansi ngokunikeza ukuqina okuyingxenye kanye nokuguquguquka.

Ama-PCB Aqinile Nagobile : Lawa ma-PCB ahlanganisa amabhodi aqinile nagobile axhunywe ngesixhumi. Nokho, ama-PCB athambile kancane ahlanganisa izingxenye eziqinile nezigobile ngaphakathi kwebhodi elilodwa, asusa isidingo sesixhumi esihlukile futhi anikeze ikhambi elihlanganiswe kakhudlwana.

Kafushane, kuyilapho ama-PCB aqinile anganikezi ukuguquguquka futhi ama-PCB aguquguqukayo anikeza ukuguquguquka okugcwele kodwa antula ukuqina, ama-PCB aguquguqukayo anikeza indawo emaphakathi, enikeza ukuguquguquka okulawulwayo kanye nokuzinza kwesakhiwo. Ukwengeza, ama-semi-flex PCB ahlinzeka ngesixazululo esididiyelwe kakhulu uma kuqhathaniswa nama-PCB aguquguqukayo aqinile, okuwenza abe ukukhetha okuguquguqukayo kwezinhlelo zokusebenza ezidinga kokubili ukuguquguquka nokuqinile ebhodini elilodwa.

Izinkinga Ezingenzeka Nezixazululo Ngesikhathi Se-FR4 Semi Flex Fabrication

Enye yezinselelo eziyinhloko ekwenzeni amabhodi e-FR4 semi-flex iqinisekisa ukubekezelela nokunemba kokugaya kokulawula ukujula ukuze kuzuzwe ukuguquguquka okufiswayo. Nakhu okucatshangelwayo okubalulekile phakathi nenqubo yokulawula ukujula kokugaya:

Isivivinyo Sokugaya Esilawulwa Ukujula A:

• Umkhiqizi usebenzisa indlela yemephu yokugaya okuwugqinsi okusele, eqinisekisa ukuthi ibhodi ligcina ukuguquguquka okwanele kokuhlolwa kokugoba okungu-90-degree.
• Ukulimala kwenqwaba yefiber yengilazi kuyimbangela evamile yokwehluleka kwe-PCB.

Ukuhlolwa Kokugaywa Okujulile B:

• Ugqinsi lwe-dielectric lwethusi phakathi kwe-L2 ne-solder mask kufanele lube phakathi kuka-0.188mm kuya ku-0.213mm.
• Ukukhiqizwa kwemishini kuyadingeka uma ubukhulu obusele ngemuva kokugaya budlula u-0.283mm, ngokubekezelela okungu-0.245mm + -0.213mm.

Isivivinyo Sokugaywa Esilawulwa Ukujula C:

• Ukufana komshini kanye ne-warpage yebhodi kungathinteka umthelela oya phambili ngenxa yokuncipha kosayizi.
• Ukugaywa kufanele kwenziwe ngokuhambisana nosayizi obekiwe ongu-6.3 X 10.5 amayintshi, indawo yokudweba ikala ukufana komshini.

Isiphetho

Ama-PCB aguquguqukayo abonisa ukuguquguquka kwezinto ezisetshenziswayo zesimanjemanje, ukuvala igebe phakathi kwama-PCB aqinile navumelana nezimo ngokugcwele nge-finesse. Ikhono labo lokunikeza ukuguquguquka okulawulwayo kanye nokuzinza kwesakhiwo kubenza babaluleke kakhulu ezimbonini ezidinga izixazululo zesekethe eziqinile, kodwa ezivumelana nezimo. Njengoba ubuchwepheshe buqhubeka buthuthuka, ukuthuthukiswa okwengeziwe ezintweni zokwakha kanye nezinqubo zokukhiqiza ngokungangabazeki kuzothuthukisa ama-PCB aguquguqukayo abe yizindima ezikhethekile nakakhulu, kuqinisekiswe ukuthi ahlala ephambili ekwakhiweni okusha kwe-elekthronikhi nokuhlanganisa.
