Ukuphonononga ukuSetyenziswa kweePCB ezicalanye kwi-Automotive Front kunye nezibane zangasemva

Ngena kwihlabathi lezibane zemoto kwaye ujonge itekhnoloji yePCB emva kwabo:

Ngaba uyachukumiseka kukukhanya okunomtsalane kwezibane zemoto? Ngaba ukhe wazibuza ngetekhnoloji emva kwale mimangaliso imangalisayo? Ngoku lixesha lokutyhila umlingo weePCB eziguqukayo kwicala elinye kunye nendima yazo ekwandiseni ukusebenza kwezibane zemoto ngaphambili nangasemva. Kule bhlog, siza kunika uhlalutyo olunzulu lwe-PCB eguqukayo yecala elinye, iimpawu zabo kunye nendlela enokuthi ihlanganiswe ngayo ngokugqibeleleyo kwinkqubo yokukhanyisa isithuthi, ngakumbi imoto ye-BYD.

ImiGaqo eSisiseko, iNgqwalasela yoYilo, izinto eziluncedo kunye nezicelo zeeBhodi zeSekethe eziShicileleyo ezinecala elinye:

Ngaphambi kokuba singene ngaphakathi, makhe sijonge izinto ezisisiseko. Ii-PCBs eziguquguqukayo ezinecala elinye, ezaziwa ngokuba ziibhodi zesekethe eziguquguqukayo ezinecala elinye, lukhetho oludumileyo kwizicelo ezininzi ngenxa yokuguquguquka kunye noyilo oludibeneyo. Zenziwe nge-polyimide ebhityileyo okanye i-mylar eqatywe ngobhedu oluncinci kwelinye icala. Olu luhlu lobhedu lusebenza njengendlela yokuqhubela phambili, evumela ukuba iimpawu zombane zihambe kwisekethe.

Xa kuyilwa icala elinye flex PCB, iinjineli kufuneka zithathele ingqalelo izinto ezifana nesicelo iimfuno mechanical, umbane ofunekayo, kunye nenkqubo yokuvelisa. Ukongezelela, i-insulating efanelekileyo kunye neengubo zokukhusela zingasetyenziswa kwiisekethe ukunyusa ukuqina kunye nokuthembeka.

Ukuguquguquka kwe-PCBs enecala elinye eguquguqukayo yenza uyilo oluntsonkothileyo nolubambeneyo, lubenze balungele usetyenziso olubambekayo kwindawo apho iiPCB zemveli ezingqongqo zingenako. Oku kuguquguquka kwakhona kuvumela i-PCB ukuba igobe, isongwe okanye ijijwe ngaphandle kokonakalisa i-circuitry, iyenze ilungele izicelo ezifuna ukuchasana nokunyakaza okanye ukungcangcazela.

Single-sided flex PCBs ziqhele ukusetyenziswa kumashishini ahlukeneyo kuquka iimoto, i-aerospace, izixhobo zonyango, i-electronics yabathengi, kunye nokunye. Ukuguquguquka kwabo kunye noyilo oludibeneyo lubenza bafaneleke kwizicelo ezifana nezinxibo, iifowuni eziphathwayo, iikhamera, izinzwa kunye nezinye izixhobo zombane apho ubukhulu, ubunzima kunye nokuguquguquka kubaluleke kakhulu.

Qinisekisa uThutho lwaMandla oluLungileyo kunye neMfezeko yoMqondiso Ngobubanzi obukhethiweyo kunye neZithuba:

Into ephambili ekuqinisekiseni ukuhanjiswa kwe-PCBs enecala elinye kububanzi bomgca kunye nesithuba somgca. Ububanzi bomgca bubhekisa kubunzima okanye ububanzi betrayisi eqhubayo kwi-PCB, ngelixa i-pitch ibhekisa kumgama ophakathi kweetrekhi eziyayameneyo. Ukugcina ububanzi bomkhondo obufanelekileyo kunye nezithuba kubalulekile ekwandiseni uqhagamshelo kunye nokunciphisa ukuphazamiseka komqondiso kwezi bhodi.

Kwesi sicelo se-PCB ye-single-sided flex PCB, indibaniselwano yobubanzi bomgca kunye nendawo ye-conductivity engcono yi-1.8 mm kunye ne-0.5 mm, ngokulandelanayo. La maxabiso amiselwa ngononophelo ngokusekwe kwizinto ezinje ngodidi lwesekethe, ukuthwala kwangoku, kunye neemfuno zemfezeko yomqondiso kwisicelo esithile.

Ububanzi bomgca we-1.8mm bubonelela ngomthamo owaneleyo wokuthwala wangoku ukuqinisekisa ukuhanjiswa kwamandla okusebenzayo kwi-PCB enecala elinye ebhetyebhetye. Yenza i-PCB ikwazi ukuphatha umthwalo wombane ofunekayo ngelixa unciphisa ilahleko exhathisayo. Oku kubaluleke ngakumbi kwizicelo ezineemfuno eziphezulu zombane, ezinje ngolawulo lweemoto okanye iisekethe zombane.

Ngakolunye uhlangothi, i-pitch ye-0.5mm inika imvume efunekayo phakathi kweendlela zokuthintela ukuphazamiseka komqondiso kunye ne-crosstalk. Inceda ukunciphisa ingxolo yombane kunye nokwenzeka kokungcoliseka komqondiso, ukuqinisekisa ukuhanjiswa kwedatha ethembekileyo kunye nokugcina imfezeko yesignali efanelekileyo. Oku kubalulekile kwiinkqubo ezibandakanya iisignali ezisebenza rhoqo, ezifana nezixhobo zonxibelelwano ezingenazingcingo okanye iisekethe zedijithali ezinesantya esiphezulu.

Ngokugcina indibaniselwano elungeleleneyo yobubanzi bomgca kunye nesithuba somgca, i-PCB ye-flexible enecala elinye inokufikelela kwi-conductivity ye-electrical conductivity ye-electrical connection esebenzayo kunye nethembekileyo. Oku akuphuculi kuphela ukusebenza kwezixhobo zombane, kodwa kwakhona kuqinisekisa ubomi obude kunye nokuqina.

Ukuqukumbela, ukukhethwa kobubanzi bomgca kunye nesithuba somgca yeyona nto iphambili ekuqinisekiseni eyona conductivity intle ye-PCB enecala elinye eguquguqukayo. Ububanzi bomgca we-1.8mm bubonelela ngomthamo owaneleyo okhoyo ngoku, kunye nomgca we-0.5mm wesithuba somgca unceda ukunciphisa ukuphazamiseka kwesignali kunye ne-crosstalk. Ukuqwalaselwa ngokucokisekileyo kwezi parameters kuqinisekisa ukuba izixhobo zombane zisebenza ngokuthembekileyo nangokufanelekileyo kwiinkqubo ezahlukeneyo.

Iprofayile ephantsi kunye nezinto eziluncedo zokubhetyebhetye kwi-PCB enecala elinye kwi-Automotive Applications:

Ibhodi ye-PCB enecala elinye eguquguqukayo yi-0.15mm ubukhulu, kwaye ubukhulu bubonke yi-1.15mm. Le profayile ebhityileyo ibenza babe khaphukhaphu, nto leyo eluncedo kwizicelo zeemoto apho ukunciphisa ubunzima kudla ngokuba yinto ephambili. Ukuguquguquka kwezi PCB kuvumela ukuba zilungelelaniswe kwiimilo ezahlukeneyo kunye noyilo, okwenza ukuba kusetyenziswe ngokufanelekileyo indawo ngaphakathi kwesithuthi.

Ngaphaya koko, ubukhulu befilimu ye-50μm bonyusa ukuqina kunye nokomelela kwezi PCB. Ifilimu isebenza njengomaleko okhuselayo, ukukhusela i-circuitry kwimingeni enokubakho yokusingqongileyo njengothuli, ukufuma, ukungcangcazela kunye nokutshintsha kweqondo lokushisa. Ukomelela okongeziweyo kuqinisekisa ixesha elide le-PCB kunye nokuthembeka kwiindawo ezinobunzima beemoto.

Kwizicelo zeemoto, apho ii-PCBs zichanabeke kwiimeko ezinzima ezinje ngotshintsho lweqondo lobushushu, ukungcangcazela, kunye nokuphazamiseka kombane we-electromagnetic, iingubo ezicwecwe zefilimu zongeza umaleko owongezelelweyo wokhuseleko kwisekethe. Inceda ukuthintela umonakalo kwimizila yobhedu kunye namacandelo, ukuqinisekisa ukuba iPCB inokumelana nocelomngeni lwemeko yokusebenza yesithuthi.

Ukuqina kunye nokuguquguquka kwezi PCB zecala elinye eziguquguqukayo zizenza zilungele usetyenziso lwezithuthi ezahlukeneyo.

Ubume obukhaphukhaphu bezi PCB bukwanegalelo ekuphuculeni ukusebenza kakuhle kwamafutha kunye nokunciphisa ubunzima bubonke, izinto eziphambili kuyilo lweemoto lwale mihla.

Ngokubanzi, ukudityaniswa kweprofayile encinci, uyilo olukhaphukhaphu, kunye nokugquma ifilimu ekhuselayo kwenza ezi PCBs eziguquguqukayo ezinecala elinye zilungele usetyenziso lweemoto. Zihlala zihlala, ziyakwazi ukunyamezela kwaye ziguquguqukayo, ziqinisekisa ukusebenza okuthembekileyo kunye nobomi obude kwiimeko ezinzima.

Ukubaluleka kokuSebenzisa i-PCBs yokuPhatha kweThermal ePhakamileyo kwiiNkqubo zokuKhanya zeMoto ukuThintela imiba eNxulumene noBubushushu:

Ukusebenza kwe-thermal yinto ebalulekileyo kwiinkqubo zombane, ngakumbi kwizicelo ezivelisa ubushushu obuninzi, njengeenkqubo zokukhanyisa iimoto. Kulo mongo, ii-PCB ezinecala elinye eziguquguqukayo ziyaziwa ngokusebenza kwazo kakuhle kwe-thermal.

Into ephambili ekusebenzeni okuphezulu kwe-thermal ye-PCB ye-flexible enecala elinye kukuqhuba kwabo kwe-thermal. Esi sicelo seePCB zeCapel zichazwe nge-thermal conductivity ye-3.00, ebonisa amandla abo okudlulisa ukushisa ngokufanelekileyo.

Amaxabiso aphezulu okuqhuba ubushushu abonisa ukuba izinto zePCB zinokuqhuba ngokufanelekileyo kwaye zikhuphe ubushushu kude nezinto ezivelisa ubushushu. Ngokwenza njalo, kunceda ukugcina ubushushu obuphezulu bokusebenza kwezinto ezithambileyo zokukhanyisa, ukuthintela nawuphi na umonakalo ovela kubushushu obugqithisileyo.

Iinkqubo zokukhanyisa iimoto, ngakumbi ezo zisebenzisa iteknoloji ye-LED, zivelisa ubushushu obuninzi ngexesha lokusebenza. Umzekelo, izibane ze-LED zivelisa ubushushu njengoko zisebenzisa umbane. Ngaphandle kokutshatyalaliswa kobushushu obufanelekileyo, obu bushushu bunokubangela ukuthotywa kokusebenza, ukungaphumeleli kwecandelo kwangaphambi kwexesha, kunye nemiba yokhuseleko.

Ngokubandakanya ii-PCB eziguquguqukayo zecala elinye kunye ne-conductivity ephezulu ye-thermal kwiinkqubo zokukhanyisa iimoto, abavelisi banokuqinisekisa ukutshatyalaliswa kobushushu obusebenzayo. Ngoko ke, ezi PCB zidlala indima ebalulekileyo ekuthinteleni umonakalo onxulumene nobushushu kunye nokugcina ukuthembeka okupheleleyo kunye nobude benkqubo yokukhanyisa.

Ukongezelela, ukuguquguquka kwee-PCB ze-flexible zecala elinye kwenza ukuba zibunjwe kwaye ziyilelwe ukuhlangabezana neemfuno ezithile zeenkqubo zokukhanyisa iimoto. Olu bhetyebhetye luqinisekisa ukuhanjiswa kobushushu ngokufanelekileyo nakwindawo ezivaliweyo okanye kwizakhiwo zeengcingo ezintsonkothileyo. Ngokuhambelana noyilo lwenkqubo, iPCB enecala elinye eguquguqukayo inokwandisa ukusebenza kakuhle kokupholisa kunye nolawulo lobushushu.
