Iipropati zokucubungula iibhodi zeesekethe eziguquguqukayo zichaphazela ukusebenza kwazo kunye nezicelo

Kule post yebhlog, siza kuntywila kukubaluleka kokuqhubekeka kwebhodi yesekethe ebhetyebhetye kwaye sijonge ukuba ikuchaphazela njani ukusebenza kwayo kunye nokusetyenziswa kwayo.

Iibhodi zesekethe eziguquguqukayo, ezikwabizwa ngokuba ziiPCB eziguquguqukayo, ziguqule icandelo lezobuchwephesha ngeempawu zazo ezizodwa kunye namandla amakhulu.Ezi bhodi zibonelela ngokuguquguquka, ukuthembeka, kunye nokuguquguquka, okwenza kube lula kwiintlobo ezahlukeneyo zezicelo.Phakathi kweempawu ezininzi ezigqiba ukusebenza kwebhodi yesekethe eguquguqukayo, inkalo ephambili yinkqubo yayo.

I-Processability ibhekisela ekukhululekeni kwebhodi yesekethe eguquguqukayo enokwenziwa ngayo, idityaniswe, kwaye idibaniswe kwizixhobo zombane.Ibandakanya iindlela ezahlukeneyo zobuchule bokuvelisa, izixhobo kunye neengqwalasela zoyilo ezichaphazela ngokuthe ngqo umgangatho kunye nokusebenza kwemveliso yokugqibela.

Ukuqhubekeka kweebhodi zeesekethe eziguquguqukayo kudlala indima ebalulekileyo ekumiseleni ukusebenza kakuhle kwemveliso kunye neendleko ezifanelekileyo.Ngokukhetha ngokucokisekileyo izixhobo ezifanelekileyo kunye neenkqubo zokuyila, abavelisi banokwandisa imveliso kunye nokudibanisa kwezi bhodi, ukunciphisa ixesha kunye neendleko.Iinkqubo ezisebenzayo zokwenziwa kwemveliso zongeza ubungakanani kunye nokwandisa imveliso, ukwenza iibhodi zeesekethe eziguquguqukayo zifikeleleke kwaye zifikeleleke kumashishini ahlukeneyo.

Enye inkalo yenkqubo echaphazela kakhulu ukusebenza kwebhodi yesekethe eguquguqukayo kukukwazi ukumelana noxinzelelo lwe-thermal.IiPCB eziguquguqukayo zidla ngokusetyenziswa kwiindawo ezinobushushu obuphezulu okanye utshintsho olukhawulezayo lobushushu.Ukuba izinto zebhodi yesiphaluka azichithi ukushisa ngokufanelekileyo, ukusebenza kwesekethe kunokuchaphazeleka, okukhokelela ekungaphumeleli okanye ukungaphumeleli.Ngoko ke, ukukhetha izinto ezinomgangatho ophezulu we-thermal conductivity kunye nokuyila iindlela zokupholisa ezifanelekileyo zibalulekile ekuqinisekiseni ukuthembeka kwexesha elide leebhodi zeesekethe eziguquguqukayo.

Enye into ephambili enxulumene nokuqhubekeka kweebhodi zeesekethe eziguquguqukayo zizinzo lwazo lwe-dimensional.Ii-PCB eziguquguqukayo zihlala ziphantsi kokugoba, ukujijeka kunye nolunye uxinzelelo lomatshini, olunokukhokelela kuguquko okanye ukusilela ukuba imathiriyeli ayizinzanga.Abavelisi kufuneka bakhethe izixhobo ezinee-coefficients ezisezantsi zokwandiswa kwe-thermal (CTE) ukunciphisa utshintsho lwe-dimensional ngenxa yokuguquguquka kweqondo lokushisa.Oku kuqinisekisa ukuba isekethe ihlala injalo kwaye isebenza naphantsi kweemeko ezigqithisileyo zoomatshini.

Ukongezelela, ukuhambelana kwezinto ezisetyenziswa kwiibhodi zeesekethe eziguquguqukayo kunye nobuchwepheshe obuhlukeneyo bokuvelisa yinto ebalulekileyo yokuqhubela phambili.Abavelisi basebenzisa iindlela ezahlukeneyo, ezifana neenkqubo zokongeza okanye ezikhuphayo, ukwenza iipatheni zesekethe kunye nomkhondo kula mabhodi.Ukukhethwa kwezinto eziphathekayo kufuneka kuhambelane neteknoloji ethile yokuvelisa esetyenziselwa ukuqinisekisa iziphumo ezilungileyo.Umzekelo, ukuba imathiriyeli ayilungelanga ubuchule bokwenza okuthile, inokukhokelela kwiingxaki ezifana nokuncamathela okulambathayo, i-delamination kunye nokusilela kweesekethe.

Ukongeza kwingqwalasela yokuvelisa, ukuqhutyelwa kweebhodi zeesekethe eziguquguqukayo nazo zichaphazela ukudibanisa kunye nokudibanisa kwizixhobo zombane.Njengoko izixhobo zombane ziqhubeka ziba zincinci kwaye zihlangene ngakumbi, ukukwazi ukudibanisa ngokungenamthungo iibhodi zesekethe eziguquguqukayo kuye kwaba yinto ebalulekileyo.Abaqulunqi kunye nabavelisi kufuneka baqinisekise ukuba iibhodi zeesekethe zinokudibaniswa ngokulula kwamanye amacandelo okanye izixhobo, ukuvumela ukudibanisa okusebenzayo kunye nokunciphisa amathuba okuba neempazamo okanye iziphene.

Ukufezekisa ukusebenza kakuhle kwenkqubo yeebhodi zeesekethe eziguquguqukayo kufuna indlela ebanzi ebandakanya isayensi yezinto, iteknoloji yokuvelisa kunye nokuqwalaselwa koyilo.Siyaqhubeka ukutyala uphando olubalulekileyo kunye neenzame zophuhliso zokuphucula ukuqhubekeka kwezi bhodi, okwenza ukuba zamkelwe kuluhlu olubanzi lwezicelo.

Ngamafutshane, ukucubungula ukusebenza kweebhodi zeesekethe eziguquguqukayo yinto ephambili ekunqumeni ukusebenza kwabo kunye nezicelo.Ukukwazi kweebhodi ukumelana noxinzelelo lwe-thermal, uzinzo lwe-dimensional kunye nokuhambelana nobugcisa bokuvelisa zonke izinto ezibalulekileyo ekuveliseni ii-PCB eziguquguqukayo ezithembekileyo nezisebenza ngokupheleleyo.Ngokuqhubeka siphucula amandla okusetyenzwa kweebhodi zesekethe eziguquguqukayo, sinokuvula amandla azo apheleleyo kwaye siqhubele phambili ukuqhubela phambili kwezobuchwephesha kunye nobuchwepheshe.
