Tlhahiso ea Ceramic Circuit Boards: Ho sebelisoa lisebelisoa life?

Ka poso ena ea blog, re tla hlahloba lisebelisoa tsa mantlha tse sebelisoang ha ho etsoa liboto tsa potoloho ea ceramic le ho buisana ka bohlokoa ba tsona bakeng sa ho fihlela ts'ebetso e nepahetseng.

Ha ho etsoa liboto tsa potoloho ea ceramic, lisebelisoa tse fapaneng li phetha karolo ea bohlokoa ho netefatsa hore li sebetsa le ho tšepahala. Liboto tsa potoloho tsa Ceramic, tse tsejoang hape e le liboto tsa potoloho tse hatisitsoeng tsa ceramic (PCBs), li sebelisoa haholo indastering e fapaneng ho kenyelletsa lisebelisoa tsa elektroniki, sefofane le likoloi ka lebaka la ts'ebetso ea tsona e ntle ea mocheso, mocheso o phahameng oa ts'ebetso le thepa e phahameng ea motlakase.

Liboto tsa potoloho tsa Ceramic li entsoe haholo ka motsoako oa lisebelisoa tsa ceramic le litšepe, tse khethiloeng ka hloko ho fihlela litlhoko tse khethehileng tsa likopo tse fapaneng.

1. Karolo e nyenyane ea Ceramic:

Motheo oa boto ea potoloho ea ceramic ke substrate ea ceramic, e fanang ka motheo oa likarolo tse ling kaofela. Aluminium oxide (Al2O3) le aluminium nitride (AlN) ke lisebelisoa tse sebelisoang haholo ka ceramic. Alumina e na le matla a matla a mochini, conductivity e phahameng ea mocheso le ho kenya motlakase hantle, ho etsa hore e tšoanelehe bakeng sa mefuta e mengata ea lits'ebetso. Aluminium nitride, ka lehlakoreng le leng, e fana ka ts'ebetso e ntle ea mocheso oa mocheso le thepa ea ho atolosa mocheso, e etsa hore e be e loketseng bakeng sa lisebelisoa tse hlokang mocheso o sebetsang hantle.

2. Mekhoa e metle:

Litsela tsa conductive li na le boikarabello ba ho tsamaisa matšoao a motlakase pakeng tsa likarolo tse fapaneng holim'a boto ea potoloho. Libotong tsa potoloho ea ceramic, li-conductor tsa tšepe tse kang khauta, silevera, kapa koporo li sebelisoa ho etsa mesaletsa ena. Litšepe tsena li khethiloe bakeng sa conductivity ea tsona e phahameng ea motlakase le ho lumellana le li-substrates tsa ceramic. Khauta ka kakaretso e ratoa ka lebaka la ts'ebetso ea eona e ntle ea ho hanyetsa kutu le thepa ea motlakase e tsitsitseng, haholo lits'ebetsong tsa maqhubu a holimo.

3. Lera la dielectric:

Likarolo tsa dielectric li bohlokoa ho sireletsa mesaletsa ea conductive le ho thibela tšitiso ea matšoao le li-circuits tse khutšoane. Ntho e tloaelehileng ka ho fetisisa ea dielectric e sebelisoang ka mapolanka a potoloho ea ceramic ke khalase. Khalase e na le thepa e ntle haholo ea ho sireletsa motlakase 'me e ka behoa e le lesela le tšesaane holim'a li-substrates tsa ceramic. Ho phaella moo, lera la khalase le ka etsoa ka mokhoa o ikhethileng hore le be le boleng bo itseng ba dielectric kamehla, ho lumella ho laola ka ho nepahetseng thepa ea motlakase ea boto ea potoloho.

4. Maske a solder le kalafo ea bokaholimo:

Mask ea solder e sebelisoa ka holim'a mesaletsa ea conductive ho li sireletsa linthong tsa tikoloho joalo ka lerole, mongobo le oxidation. Li-mask tsena hangata li entsoe ka thepa ea epoxy kapa polyurethane e fanang ka tšireletso le tšireletso. Sebelisa liphekolo tse ka holimo tse kang thini e qoelisoang kapa plating ea khauta ho matlafatsa boto hore e sollehe le ho thibela oxidation ea mesaletsa ea koporo e pepeneneng.

5. Ka lisebelisoa tsa ho tlatsa :

Li-Vias ke masoba a manyane a phuntsoeng ka boto ea potoloho e lumellang likhokahano tsa motlakase lipakeng tsa likarolo tse fapaneng tsa boto. Libotong tsa potoloho ea ceramic, ka lisebelisoa tsa ho tlatsa li sebelisoa ho tlatsa likoti tsena le ho netefatsa hore motlakase o ts'epahala. Tse tloaelehileng ka lisebelisoa tsa ho tlatsa li kenyelletsa li-paste tse tsamaisang kapa li-filler tse entsoeng ka silevera, koporo kapa likaroloana tse ling tsa tšepe, tse kopantsoeng le likhalase kapa li-ceramic fillers. Kopano ena e fana ka botsitso ba motlakase le mechine, ho netefatsa hore ho na le kamano e matla pakeng tsa lihlopha tse fapaneng.

Ka kakaretso

Ho hlahisa liboto tsa potoloho ea ceramic ho kenyelletsa motsoako oa lisebelisoa tsa ceramic, tšepe le lintho tse ling tse khethehileng. Aluminium oxide le aluminium nitride li sebelisoa e le substrates, ha litšepe tse kang khauta, silevera le koporo li sebelisoa bakeng sa mesaletsa ea conductive. Khalase e sebetsa joalo ka thepa ea dielectric, e fana ka insulation ea motlakase, 'me mask a epoxy kapa polyurethane solder e sireletsa mesaletsa ea conductive. Kamano pakeng tsa lihlopha tse fapaneng e thehiloe ka thepa ea ho tlatsa e nang le li-conductive paste le li-fillers.

Ho utloisisa lisebelisoa tse sebelisoang ha ho etsoa liboto tsa potoloho ea ceramic ho bohlokoa bakeng sa baenjiniere le baqapi ho nts'etsapele lisebelisoa tsa elektroniki tse sebetsang hantle le tse tšepahalang. Ho khetha thepa e nepahetseng ho itšetlehile ka litlhoko tse khethehileng tsa kopo tse kang conductivity ea mocheso, thepa ea motlakase le maemo a tikoloho. Ka ho sebelisa thepa e ikhethang ea thepa e 'ngoe le e' ngoe, liboto tsa potoloho ea ceramic li tsoela pele ho fetola liindasteri tse fapaneng ka ts'ebetso ea tsona e phahameng le ho tšoarella.
