Ihlabathi letekhnoloji lihlala livela kwaye kunye nemfuno yeebhodi zesekethe eziphucukileyo neziphucukileyo (PCBs). IiPCB ziyinxalenye ebalulekileyo yezixhobo zombane kwaye zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kwazo.Ukuhlangabezana nemfuno ekhulayo, abavelisi kufuneka bajonge iinkqubo ezikhethekileyo kunye nobugcisa, obufana nokungaboni ngokusebenzisa izigqubuthelo zobhedu, ukuphucula ukusebenza kwePCB. Kule post yebhlog, siza kuphonononga amathuba okuphumeza ezi nkqubo zikhethekileyo kwimveliso yePCB.
Ii-PCBs zenziwa ikakhulu kusetyenziswa iileya zobhedu ezilaminethiweyo kwi-non-conductive substrate, edla ngokuqulunqwa nge-fiberglass-reinforced epoxy.Ezi maleko zifakwe ukwenza udibaniso lombane olufunekayo kunye namacandelo ebhodini. Ngelixa le nkqubo yokwenziwa kwemveli isebenza kuninzi lwezicelo, ezinye iiprojekthi zinokufuna iimpawu ezongezelelweyo kunye nokusebenza okungenakufezekiswa ngeendlela zemveli.
Enye inkqubo ekhethekileyo kukubandakanya iimfama ngokusebenzisa izigqubuthelo zobhedu kwiPCB.vias Blind yi imingxunya non-ngokusebenzisa ukuba ukwandisa kuphela ubunzulu ethile ngaphakathi ebhodini kunokuba ngokupheleleyo ngebhodi. Ezi ndlela zingaboniyo zinokuzaliswa ngobhedu ukwenza imidibaniso ekhuselekileyo okanye igqume amacandelo abuthathaka. Obu buchule buluncedo ngakumbi xa indawo incinyiwe okanye iindawo ezahlukeneyo kwi-PCB zifuna amanqanaba ahlukeneyo okuqhuba okanye ukukhuselwa.
Enye yeenzuzo eziphambili zeemfama ngokusebenzisa izigqubuthelo zobhedu kukuthembeka okuphuculweyo.Isigcwalisi sobhedu sibonelela ngenkxaso yomatshini ephuculweyo kwiindonga zomngxuma, ukunciphisa umngcipheko we-burrs okanye umonakalo owenziweyo ngexesha lokuvelisa. Ukongezelela, i-copper filler inikezela nge-conductivity eyongezelelweyo ye-thermal, inceda ukukhupha ubushushu ukusuka kwicandelo, ngaloo ndlela ikhulise ukusebenza kwayo yonke kunye nokuphila ixesha elide.
Kwiiprojekthi ezifuna iimfama ngeekhava zobhedu, izixhobo ezikhethekileyo kunye neteknoloji ziyafuneka ngexesha lenkqubo yokuvelisa.Ukusebenzisa oomatshini bokugrumba abaphambili, imingxuma eyimfama yobukhulu obahlukeneyo kunye neemilo inokugrunjwa ngokuchanekileyo. Aba matshini baxhotyiswe ngeenkqubo zokulawula ezichanekileyo eziqinisekisa iziphumo ezihambelanayo nezithembekileyo. Ukongezelela, inkqubo inokufuna amanyathelo amaninzi okugaya ukufezekisa ubunzulu obufunwayo kunye nokumila komngxuma oyimfama.
Enye inkqubo ekhethekileyo yokwenziwa kwePCB kukuphunyezwa kwe-vias engcwatywayo.I-Vis engcwatywayo yimingxuma edibanisa iileya ezininzi ze-PCB kodwa ayinwebeki kumaleko angaphandle. Le teknoloji inokudala iisekethe eziyinkimbinkimbi ze-multi-layer ngaphandle kokunyusa ubungakanani bebhodi. Ukungcwatywa kwee-vias kwandisa ukusebenza kunye nokuxinana kwee-PCBs, zizenza zixabiseke kwizixhobo zombane zanamhlanje. Nangona kunjalo, ukuphumeza ii-vias ezingcwatywayo kufuna ukucwangciswa ngononophelo kunye nokwenziwa okuchanekileyo, njengoko imingxuma kufuneka ilungelelaniswe ngokuchanekileyo kwaye yombiwe phakathi kweeleya ezithile.
Indibaniselwano yeenkqubo ezikhethekileyo kwimveliso PCB, ezifana iimfama ngokusebenzisa amagqubuthela ubhedu kunye vias wangcwatywa, ngokungathandabuzekiyo kwandisa ukuntsonkotha inkqubo imveliso.Abavelisi kufuneka batyale imali kwizixhobo ezikumgangatho ophezulu, baqeqeshe abasebenzi kubuchule bobugcisa, kwaye baqinisekise ukuba kukho amanyathelo angqongqo okulawula umgangatho. Nangona kunjalo, iingenelo kunye nesakhono esongeziweyo esibonelelwa ngezi nkqubo sibenza babaluleke kakhulu kwizicelo ezithile, ngakumbi ezo zifuna isekethe ephucukileyo kunye neminiaturization.
Isishwankathelo, iinkqubo ezikhethekileyo kwimveliso PCB, ezifana iimfama ngokusebenzisa iminqwazi yobhedu kunye vias wangcwatywa, akunakwenzeka kuphela kodwa kuyimfuneko kwezinye iiprojekthi.Ezi nkqubo ziphucula ukusebenza kwe-PCB, ukuthembeka, kunye nokuxinana, zizenza zilungele izixhobo zombane ezikumgangatho ophezulu. Ngelixa bafuna utyalo-mali olongezelelweyo kunye nezixhobo ezikhethekileyo, banikezela ngeenzuzo ezodlula imingeni. Njengoko iteknoloji iqhubela phambili, abavelisi kufuneka bahambisane nezi nkqubo zikhethekileyo ukuhlangabezana neemfuno eziguqukayo zeshishini.
