Izinketho zeeleyile eziqhubayo zeebhodi zeesekethe eziguquguqukayo

Kule bhlog, siza kuphonononga iinketho ezahlukeneyo ezikhoyo kwiileya eziqhubayo kwiibhodi zesekethe eziguquguqukayo.

Iibhodi zesekethe eziguquguqukayo, ezikwaziwa ngokuba ziibhodi zesekethe eziguquguqukayo (iiPCB) okanye i-elektroniki ebhetyebhetye, ziye zafumana udumo olukhulu kwiminyaka yakutshanje ngenxa yeempawu zazo ezizodwa kunye neengenelo ngaphezulu kweePCB zemveli eziqinileyo. Ukukwazi kwabo ukugoba, ukujija kunye nokugoba kubenza balungele uluhlu olubanzi lwezicelo kumashishini afana neemoto, i-aerospace, ukunakekelwa kwezempilo kunye nobuchwepheshe obunxitywayo.

Enye yezinto eziphambili zebhodi yesekethe eguquguqukayo ngumaleko wayo wokuqhuba. Ezi maleko zinoxanduva lokuhambisa imiqondiso yombane kunye nokuququzelela ukuhamba kombane kwisekethe. Ukukhethwa kwezinto zokuqhuba ezi maleko kudlala indima ebalulekileyo ekusebenzeni ngokubanzi kunye nokuthembeka kwe-PCB eguquguqukayo.

1. Ifoyile yobhedu:

Ifoyile yobhedu yeyona nto isetyenziswa ngokuqhelekileyo umaleko wokuqhuba kwiibhodi zesekethe eziguquguqukayo. Ine-conductivity egqwesileyo, ukuguquguquka kunye nokuqina. I-foil yobhedu ifumaneka kwiindidi ezahlukeneyo, ngokuqhelekileyo i-12 ukuya kwi-70 microns, evumela abaqulunqi ukuba bakhethe ubukhulu obufanelekileyo ngokusekelwe kwiimfuno ezithile zesicelo sabo. I-foil yobhedu esetyenziswe kwiibhodi zeesekethe eziguquguqukayo ngokuqhelekileyo ziphathwa nge-adhesive okanye i-agent edibeneyo ukuze kuqinisekiswe ukunamathela okuqinileyo kwi-substrate eguquguqukayo.

2. I-inki eqhubayo:

I-inki ye-conductive yenye inketho yokudala iileya zokuqhuba kwiibhodi zesekethe eziguquguqukayo. Le inki iqulathe amasuntswana conductive axhonywe kulwelo medium, ezifana namanzi okanye isinyibilikisi eziphilayo. Ingasetyenziselwa kwii-substrates eziguquguqukayo usebenzisa iindlela ezahlukeneyo zobuchule, ezifana nokuprintwa kwesikrini, ukuprintwa kwe-inkjet okanye ukutshiza. Ii-inki zokuqhuba nazo zinenzuzo eyongezelelweyo yokudala iipateni zesekethe ezintsonkothileyo ezinokuthi zilungelelaniswe ukuhlangabezana neemfuno zoyilo oluthile. Nangona kunjalo, zisenokungaqhubeki njengefoyile yobhedu kwaye zinokufuna iingubo ezongezelelweyo ezikhuselayo zokwandisa ukuqina kwazo.

3. Iglu eqhubayo:

I-adhesives ye-conductive yindlela ehlukile kwiindlela zemveli ze-soldering ekudaleni iileyile zokuqhuba kwiibhodi zeesekethe eziguquguqukayo. Ezi zikhonkwane ziqulethe iinqununu ze-conductive, ezifana nesilivere okanye i-carbon, zihlakazwe kwi-polymer resin. Zingasetyenziselwa ukudibanisa amacandelo ngokuthe ngqo kwi-substrates eguquguqukayo, ukuphelisa imfuno yokuthengisa. I-conductive adhesives iqhuba kakuhle umbane kwaye inokumelana nokugoba nokugoba ngaphandle kokuchaphazela ukusebenza kwesekethe. Nangona kunjalo, banokuba namanqanaba aphezulu okuchasa xa kuthelekiswa ne-foil yobhedu, enokuthi ichaphazele ukusebenza kakuhle kwesekethe.

4. Ifilimu eyenziwe ngesinyithi:

Iifilimu ezenziwe ngesinyithi, ezinje nge-aluminiyam okanye iifilimu zesilivere, zinokusetyenziswa njengomaleko okuqhubayo kwiibhodi zesekethe eziguquguqukayo. Ezi bhanyabhanya zidla ngokufakwa kwi-vacuum kwi-substrates eguquguqukayo ukwenza umaleko ofanayo kunye noqhubekayo wokuqhuba. Iifilimu ezenziwe ngesinyithi zinomgangatho obalaseleyo wombane kwaye zinokwenziwa iipateni kusetyenziswa iindlela zokutshiza okanye zokukhupha i-laser. Nangona kunjalo, banokuba nemida ekuguquguqukeni ngenxa yokuba iileya zetsimbi ezifakiweyo zinokuqhekeka okanye zinciphise xa zigobile ngokuphindaphindiweyo okanye zijijekile.

5. Igraphene:

IGraphene, umaleko omnye weeathom zekhabhoni ezicwangciswe kwihexagonal lattice, ithathwa njengesixhobo esithembisayo kwiileya zokuqhuba kwiibhodi zesekethe eziguquguqukayo. Ine-conductivity egqwesileyo yombane kunye ne-thermal, kunye namandla abalaseleyo omatshini kunye nokuguquguquka. IGraphene ingafakwa kwiisubstrates eziguquguqukayo kusetyenziswa iindlela ezahlukeneyo, ezifana nekhemikhali yokubeka umphunga okanye inkjet yoshicilelo. Nangona kunjalo, ixabiso eliphezulu kunye nobunzima bokuveliswa kwegraphene kunye nokulungiswa okwangoku kunciphisa ukwamkelwa kwayo ngokubanzi kwizicelo zorhwebo.

Isishwankathelo, kukho iinketho ezininzi zeeleyile eziqhubayo kwiibhodi zeesekethe eziguquguqukayo, nganye ineengenelo zayo kunye nemida. I-copper foil, i-inki e-conductive, i-adhesives conductive, iifilimu ze-metalized kunye ne-graphene zonke zineempawu ezizodwa kwaye ziyakwazi ukulungelelaniswa kwiimfuno ezithile zezicelo ezahlukeneyo.Abaqulunqi kunye nabavelisi kufuneka bavavanye ngononophelo olu khetho kwaye bakhethe eyona imathiriyeli efanelekileyo ngokusekwe kwizinto ezifana nokusebenza kombane, ukuqina, ukuguquguquka, kunye neendleko.
