Ukuyila nayiphi na iPCB kulucelomngeni, ngakumbi njengoko izixhobo zisiba ncinci kwaye zincinci. Uyilo lwePCB oluphezulu lwangoku luntsonkothe ​​ngakumbi kuba lunemiqobo efanayo kwaye lufuna iseti eyongezelelweyo yezinto ezizodwa ekufuneka ziqwalaselwe.
Iingcali ziqikelela ukuba imfuno yezixhobo eziphezulu zamandla inokuthi inyuke ukuze ifikelele amanani aphindwe kabini ngonyaka kwi-Industrial iot ngo-2030. Nazi iindlela ezisixhenxe zokuphucula uyilo lwePCB kwi-elektroniki yangoku ephezulu kulo mkhwa.

1.Qinisekisa ubungakanani obaneleyo bekhebula
Ubungakanani bomgca yenye yezona ngqwalasela ibalulekileyo yoyilo kwiPCBS yangoku ephezulu. Iingcingo zobhedu zithande ukwenziwa zincinci kuyilo oludityanisiweyo, kodwa oku akusebenzi kwimisinga ephezulu. Inxalenye encinci yomnqamlezo inokukhokelela ekulahlekeni kwamandla ngokutshatyalaliswa kobushushu, ngoko ke ubungakanani bengoma enkulu ngokufanelekileyo iyafuneka.
Unokutshintsha indawo ye-cross-sectional of the wire ngokulungelelanisa izinto ezimbini: ububanzi bocingo kunye nobukhulu bobhedu. Ukulinganisa ezi zimbini ngundoqo ekunciphiseni ukusetyenziswa kwamandla kunye nokugcina ubungakanani obufanelekileyo bePCB.
Sebenzisa i-PCB Ububanzi bomgca wokubala ukufunda ukuba bobuphi na ububanzi nobukhulu obuxhasa uhlobo lwangoku olufunekayo kwisixhobo sakho. Xa usebenzisa ezi zixhobo, qaphela ukuyila ubungakanani bocingo ukuxhasa imisinga ephezulu kunokuba ucinga ukuba uyayidinga.

2.Cinga ngokutsha ukubekwa kwecandelo
Uyilo lwecandelo lolunye uqwalaselo oluphambili kuyilo lwePCB lwangoku. Ii-MOSFET kunye nezinto ezifanayo zivelisa ubushushu obuninzi, ngoko ke kubalulekile ukuzigcina zikwanti kwezinye iindawo ezishushu okanye ezingevayo kubushushu kangangoko kunokwenzeka. Oku akusoloko kulula xa ujongana nezinto ezincitshisiweyo zeefom.
I-amplifiers kunye neziguquli kufuneka zigcinwe kumgama ofanelekileyo ukusuka kwi-MOSFETs kunye nezinye izinto zokufudumeza. Nangona kunokuba nzima ukugcina ummandla wamandla aphezulu emphethweni, oku akuvumeli ukusabalalisa ubushushu obufanayo. Endaweni yoko, zibekwe kwimigca ethe tye kwibhodi ukuze kugcinwe amandla, nto leyo eyenza ubushushu ngakumbi.
Ngokusondela kwezona ndawo zinempembelelo kuqala, kulula ukumisela amacandelo afanelekileyo. Okokuqala, misela indawo efanelekileyo yamacandelo aphezulu obushushu. Wakuba uyazi apho uzibeke khona, ungasebenzisa ezinye ukuze ugcwalise izithuba.

3.Ukwandisa ulawulo lokutshatyalaliswa kobushushu
Ngokufanayo, i-PCBS ephezulu yangoku ikwafuna ulawulo olucokisekileyo lobushushu. Kwiinkqubo ezininzi, oku kuthetha ukugcina ubushushu bangaphakathi bungaphantsi kwe-130 degrees celcius kwiqondo lobushushu beglasi le-FR4 laminates. Ukuphucula ukubekwa kwecandelo kuya kunceda, kodwa amanyathelo akho okunciphisa ubushushu kufuneka ayeke apho.
Ukupholisa kwe-convection yendalo kunokwanela kwi-PCBS yombane omncinci wabathengi, kodwa kunokunganeli kwizicelo zamandla aphezulu. Iiradiyetha zoomatshini zingafuneka. Ukupholisa okusebenzayo okufana neefeni okanye iinkqubo zokupholisa ulwelo ezingqonge ii-MOSFET nazo ziyanceda. Nangona kunjalo, ezinye iidizayini zesixhobo zisenokungabi nkulu ngokwaneleyo ukulungiselela iiradiyetha zemveli okanye ukupholisa okusebenzayo.
KwiiPCBS ezincinci kodwa ezisebenza kakhulu, ukukhutshwa kobushushu kwimingxuma yeyona ndlela iluncedo. Isinyithi esisebenza kakhulu esinothotho lwemingxuma ethululwayo siya kususa ubushushu kwii-MOSFET okanye kumalungu afanayo phambi kokuba bufike kwiindawo ezinobuthathaka.

4.Sebenzisa izinto ezifanelekileyo
Ukukhethwa kwezinto eziphathekayo kuya kuba luncedo olukhulu xa kulungiswa ulawulo lwe-thermal kunye nokuqinisekisa ukuba amacandelo anokumelana nemisinga ephezulu. Oku kusebenza kumacandelo PCB kunye substrates.
Nangona i-FR4 iyeyona substrate ixhaphakileyo, ayisoloko ilolona khetho lubalaseleyo kuyilo lwePCB lwangoku. I-Metal-core PCBS inokuba yinto efanelekileyo kuba ilungelelanisa ukugquma kunye nokusebenza kakuhle kwee-substrates ezifana ne-FR4 kunye namandla kunye nokufuduka kweqondo lokushisa kweentsimbi eziqhuba kakhulu. Kungenjalo, abanye abavelisi benza iilaminates ezikhethekileyo zokumelana nobushushu onokuthi uziqwalasele.
Kwakhona, kufuneka usebenzise kuphela amacandelo anamaxabiso aphezulu okumelana ne-thermal. Ngamanye amaxesha, oku kuthetha ukukhetha izinto ezikwazi ukumelana nobushushu, ngelixa kwezinye iimeko kuthetha ukusebenzisa amacandelo angqingqwa esixhobo esifanayo. Loluphi ukhetho olungcono luxhomekeke kubungakanani bePCB yakho, ibhajethi, kunye nababoneleli abakhoyo.

5.Ukuphucula inkqubo yokulawula umgangatho
Ukuthembeka kwe-PCBS ephezulu yangoku kwakhona ngumcimbi wokufumana iimpazamo kwimveliso. Ukuba inkqubo yokuvelisa ayinakufumana kwaye ilungise iziphene ezilungisa iinzuzo zayo, ke ezi zikhetho zine ezingentla aziyi kuvelisa uphuculo oluninzi. Iitshekhi ezithembeke ngakumbi zomgangatho wophindaphindo lweprototype nazo zibalulekile.
Ukusebenzisa izixhobo ezifanelekileyo ukuvavanya umgangatho we-PCB yenye yezona ngqwalasela zibalulekileyo endle. Abathelekisi beDigital optical njengeetemplates kunye nezigqubuthelo zigqwesa iindlela zemveli njengoko zolula kwaye zigqwethe ngokuhamba kwexesha, zithintela ukuthembeka kwazo. Kuya kufuneka kwakhona uqwalasele izixhobo ekulula ukuzenza ngokuzenzekelayo ukunciphisa umngcipheko wempazamo yomntu.
Nokuba zeziphi iindlela kunye neendlela ozisebenzisayo, ukulandelela zonke iziphene kubalulekile. Ngokuhamba kwexesha, le datha inokutyhila iintsingiselo ekuveleni kweengxaki, ibonelela ngotshintsho oluthembekileyo loyilo lwePCB.

6.Uyilo lokwenziwa kwezinto
Into efanayo kodwa ihlala ingahoywa kuyilo lwePCB yangoku ephezulu kukuqinisekisa ukwenziwa lula. Ukuba iimpazamo zemveliso zixhaphake kangangokuba isixhobo asifane sihlangabezane neenkcukacha ephepheni, akunamsebenzi nokuba ithembeke kangakanani na iPCB kwithiyori.
Isisombululo kukuphepha uyilo oluntsonkothileyo okanye oluntsonkothileyo kangangoko kunokwenzeka. Xa uyila i-PCBS ephezulu yangoku, gcina inkqubo yakho yokuvelisa engqondweni, ucingela ukuba oku kuhamba komsebenzi kunokuvelisa njani kwaye zeziphi iingxaki ezinokuvela. Okukhona unokwenza iimveliso ezingenazimpazamo, kokukhona ziya kuthembeka ngakumbi.
Eli nyathelo lifuna intsebenziswano esondeleyo nabachaphazelekayo kwimveliso. Ukuba awuphathi imveliso yangaphakathi, bandakanya amaqabane akho emveliso kwisigaba soyilo ukuze ufumane igalelo labo kwimiba enokwenzeka yokwenziwa.

7.Sebenzisa iteknoloji ukuze uzuze
Ucwangciso olutsha kunye nobuchule bemveliso bunokwenza ulungelelwaniso olu qwalaselo lube lula. Ushicilelo lwe-3D lwazisa ukuguquguquka koyilo ngakumbi ukuxhasa uyilo oluntsonkothileyo lwePCB ngaphandle kweempazamo zemveliso. Ukuchaneka kwayo kukuvumela ukuba uqinisekise ukuba i-wiring yobhedu ilandela ijika kunokuba i-Angle efanelekileyo ukunciphisa ubude bayo kunye nokunciphisa ukusetyenziswa kwamandla.
Ubukrelekrele bokwenziwa bobunye ubuchwepheshe obufanele ukuphandwa. Izixhobo ze-AI PCB zinokubeka ngokuzenzekelayo amacandelo okanye ziqaqambise iingxaki zoyilo ezinokubakho ukuthintela iimpazamo ukuba zingaveli kwihlabathi lokwenyani. Izisombululo ezifanayo zinokulinganisa iimeko ezahlukeneyo zokuvavanya ukuvavanya ukusebenza kwe-PCBS ngaphambi kokuvelisa iiprototypes zomzimba.

Uyilo oluphezulu lwePCB lwangoku lufuna ukulumka
Ukuyila i-PCB ethembekileyo ephezulu yangoku akukho lula, kodwa akunakwenzeka. Ukulandela la manyathelo asixhenxe kuya kukunceda uphucule inkqubo yakho yoyilo ukwenza izixhobo ezisebenza ngamandla aphezulu.
Njengoko i-Intanethi ye-Intanethi yeZinto ikhula, ezi ngqwalasela ziya kubaluleka ngakumbi. Ukuzamkela ngoku kuya kuba sisitshixo sokuphumelela okuqhubekayo kwixesha elizayo.
