Intshayelelo

Iibhodi zesekethe eziprintiweyo eziguquguqukayo (FPCs) ziguqula ishishini le-electronics, zinika ukuguquguquka okungenakulinganiswa kunye noyilo olunokwenzeka.Njengoko imfuno yezixhobo zombane ezixineneyo nezikhaphukhaphu ziqhubeka nokukhula, ii-FPCs zidlala indima ebalulekileyo ekwenzeni izisombululo zoyilo oluyilayo noluguquguqukayo.Phakathi kweentlobo ngeentlobo zee-FPCs, ii-PCB eziguquguqukayo ezi-2 zibalasele ngokuguquguquka kwazo kunye nokusetyenziswa kwazo kuluhlu olubanzi lwamashishini.Kwesi sikhokelo sibanzi, siza kuphonononga uyilo kunye neprototyping inkqubo ye-2-layer flexible PCBs, sigxile kwizicelo zazo, imathiriyeli, iinkcukacha, kunye nokugqitywa komphezulu.

Uhlobo lweMveliso:I-2-Layer Flexible PCB

I-PCB ye-2-layer flex, eyaziwa ngokuba yi-flexible-sided flex circuit, yibhodi yesekethe eprintiweyo eguquguqukayo equka imigangatho emibini yokuqhubela phambili eyahlulwe yi-flexible dielectric layer.Olu lungelelwaniso lubonelela abaqulunqi ngokuguquguquka kwindlela yokulandela umkhondo kumacala omabini e-substrate, okuvumela ukuntsonkotha okukhulu koyilo kunye nokusebenza.Ukukwazi ukufaka izinto kumacala omabini ebhodi kwenza i-2-layer flex PCBs ilungele usetyenziso olufuna ingxinano ephezulu kunye nemiqobo yendawo.

Usetyenziso

I-versatility ye-2-layer flex PCBs ibenza bafaneleke kwiintlobo ezahlukeneyo zezicelo kumashishini ahlukeneyo.Esinye sezicelo ezibalaseleyo ze-2-layer flexible PCB ikwinkalo ye-automotive electronics.Kwishishini leemoto, indawo kunye nokugcinwa kwesisindo zizinto eziphambili, kunye ne-2-layer flex PCBs zinika ukuguquguquka ukuhlangabezana nezi mfuno.Zisetyenziswa kwiinkqubo zokulawula iimoto, izivamvo, izibane, iinkqubo ze-infotainment, nokunye.Ishishini leemoto lixhomekeke ekomeleleni nasekuthembekeni kwe-2-layer flexible PCBs ukuqinisekisa ukusebenza okungaguqukiyo kwiindawo ezinomngeni.

Ukongeza kwizicelo zeemoto, ii-PCB ezi-2 eziguquguqukayo zisetyenziswa kakhulu kubathengi be-elektroniki, izixhobo zonyango, i-aerospace kunye nezixhobo zoshishino.Ukukwazi kwabo ukuziqhelanisa neemilo ezingaqhelekanga, ukunciphisa ubunzima kunye nokunyusa ukuthembeka kubenza babaluleke kakhulu kwiimveliso ze-elektroniki ezahlukeneyo.

Izinto eziphathekayo

I-2-Layer Flexible PCB Ukukhetha izinto eziphathekayo kubalulekile ekumiseleni ukusebenza kwebhodi, ukuthembeka, kunye nokwenziwa.Izinto eziphambili ezisetyenziselwa ukwakha i-PCB ye-2-layer flexible ziquka ifilimu ye-polyimide (PI), ubhedu, kunye ne-adhesives.I-Polyimide yinto ekhethiweyo ye-substrate ngenxa yokuzinza kwayo kwe-thermal, ukuguquguquka kunye nokumelana nokushisa okuphezulu.I-foil ye-Copper isetyenziswe njengento eqhubayo, ene-conductivity egqwesileyo kunye ne-solderability.Izinto ezincamathelayo zisetyenziselwa ukudibanisa iileya zePCB kunye, ukuqinisekisa ukuzinza koomatshini kunye nokugcina ingqibelelo yesekethe.

Ububanzi bomgca, isithuba somgca kunye nobukhulu bebhodi

Xa uyila i-PCB eguquguqukayo ye-2-layer, ububanzi bomgca, isithuba somgca kunye nobukhulu bebhodi yiparameters eziphambili, ezichaphazela ngokuthe ngqo ukusebenza kunye nokuveliswa kwebhodi.Ububanzi bomgca oqhelekileyo kunye nesithuba somgca we-2-layer flexible PCBs zichazwe njenge-0.2mm / 0.2mm, ebonisa ububanzi obuncinane beetrayisi ze-conductive kunye nezithuba phakathi kwazo.Le milinganiselo ibalulekile ukuze kuqinisekiswe imfezeko yomqondiso ofanelekileyo, ulawulo lwe-impedance, kunye ne-solder ethembekileyo ngexesha lokuhlanganisa.Ukongezelela, ubukhulu bebhodi be-0.2mm +/- 0.03mm budlala indima ebalulekileyo ekunqumeni ukuguquguquka, ukugoba i-radius kunye neempawu zomatshini ezipheleleyo ze-2-layer flex PCB.

Ubuncinane boMngxuma woMngxuma kunye noNyango loMphezulu

Ukufezekisa ubungakanani bomngxunya obuchanekileyo kunye nobuguquguqukayo kubalulekile kuyilo lwePCB ene-2-layer ebhetyebhetye, ngakumbi xa kujongwa umkhwa omncinci wombane.Ubuncinci bobungakanani bomngxuma obuchaziweyo obuyi-0.1 mm bubonisa amandla e-PCBs ene-2-layer flex ukwamkela izinto ezincinci kunye nezipakishwe ngokuxineneyo.Ukongeza, unyango lwangaphezulu ludlala indima ephambili ekuphuculeni ukusebenza kombane kunye nokuthengiswa kweePCBs.I-Electroless Nickel Immersion Gold (ENIG) enobunzima be-2-3uin lukhetho oluqhelekileyo lwe-2-layer flexible PCBs kwaye ibonelela ngokugqwesa ukuxhathisa ukudleka, ukucaba, kunye nokuthengiswa.Unyango lomphezulu we-ENIG luluncedo kakhulu ekwenzeni amacandelo e-pitch-pitch kunye nokuqinisekisa iindawo ezithembekileyo ze-solder.

Impedance kunye noNyamezelo

Kwi-high-speed yedijithali kunye nezicelo ze-analog, ulawulo lwe-impedance lubalulekile ekugcineni ukunyaniseka komqondiso kunye nokunciphisa ukuphazamiseka kwesignali.Nangona kungekho xabiso lithile lokuthintela libonelelweyo, ukukwazi ukulawula i-impedance ye-2-layer flex PCB ibalulekile ukuhlangabezana neemfuno zokusebenza kweesekethe ze-elektroniki.Ukongeza, ukunyamezela kucaciswe njenge-±0.1mm, okubhekiselele ekuphambukeni okuvumelekileyo kwe-dimensional ngexesha lenkqubo yokuvelisa.Ulawulo lokunyamezelana okuqinileyo lubalulekile ekuqinisekiseni ukuchaneka kunye nokungaguquguquki kwimveliso yokugqibela, ngakumbi xa ujongana neempawu ezincinci kunye noyilo oluntsonkothileyo.

2 Umaleko Flexible PCB Prototyping Inkqubo

Iprototyping linqanaba elibalulekileyo kuphuhliso lwe-PCB ye-2-layer flex, evumela abaqulunqi ukuba baqinisekise ukuyila, ukusebenza, kunye nokusebenza ngaphambi kokuba baqhubele phambili kwimveliso epheleleyo.Inkqubo yeprototyping ibandakanya amanyathelo aphambili aliqela, kubandakanywa ukuqinisekiswa koyilo, ukukhetha imathiriyeli, ukwenziwa, kunye novavanyo.Ukuqinisekiswa koyilo kuqinisekisa ukuba ibhodi ihlangabezana neemfuno ezichaziweyo kunye nokusebenza, ngelixa ukukhethwa kwezinto kubandakanya ukukhetha i-substrate efanelekileyo, izinto zokuqhuba kunye nokuphathwa kwendawo esekelwe kwisicelo kunye neendlela zokusebenza.

Ukwenziwa kweprototypes ye-PCB ene-2-layer flexible ibandakanya ukusetyenziswa kwezixhobo ezizodwa kunye neenkqubo zokudala i-substrate eguquguqukayo, ukusebenzisa iipatheni zokuqhuba, kunye nokudibanisa amacandelo.Ubuchule bokuvelisa obukwinqanaba eliphezulu obunje ngokugrumba i-laser, i-plating ekhethiweyo kunye nokulawulwa kwe-impedance routing zisetyenziselwa ukufezekisa ukusebenza okufunekayo kunye neempawu zokusebenza.Nje ukuba iprototype yenziwe, uvavanyo olungqongqo kunye nenkqubo yokuqinisekisa iyenziwa ukuvavanya ukusebenza kombane, ukuguquguquka koomatshini kunye nokuthembeka phantsi kweemeko ezahlukeneyo zokusingqongileyo.Ingxelo evela kwinqanaba lokubonisa iprototyping inceda ukuyila kunye nokuphucula, ekugqibeleni kubangele uyilo olomeleleyo noluthembekileyo lwe-PCB eguquguqukayo ye-2-layer elungele imveliso yobuninzi.
