Iibhodi zeeSekethe zeCeramic Ukwenziwa kokuveliswa: Zeziphi izinto ezisetyenziswayo?

Kule post yeblogi, siza kuphonononga izinto eziphambili ezisetyenziselwa ukuveliswa kweebhodi zeesekethe ze-ceramic kwaye sixoxe ngokubaluleka kwazo ekufezekiseni ukusebenza kakuhle.

Ukuveliswa kweebhodi zeesekethe ze-ceramic, izinto ezahlukeneyo zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kwazo kunye nokuthembeka. Iibhodi zeesekethe zeCeramic, ezikwabizwa ngokuba ziibhodi zesekethe eziprintiweyo (i-PCBs), zisetyenziswa ngokubanzi kumashishini ahlukeneyo abandakanya i-elektroniki, i-aerospace kunye neenqwelomoya ngenxa yokuhanjiswa kwazo okugqwesileyo kwe-thermal, ubushushu obuphezulu bokusebenza kunye neepropati zombane eziphezulu.

Iibhodi zeesekethe zeCeramic ziqulunqwe ngokukodwa ngokudibanisa izinto ze-ceramic kunye neentsimbi, ezikhethwe ngononophelo ukuhlangabezana neemfuno ezithile zezicelo ezahlukeneyo.

1. Isiseko seCeramic:

Isiseko sebhodi yesekethe ye-ceramic yi-substrate ye-ceramic, enika isiseko kuwo onke amanye amacandelo. I-aluminium oxide (i-Al2O3) kunye ne-aluminium nitride (i-AlN) zezona zinto zisetyenziswa ngokuqhelekileyo kwi-ceramic. I-Alumina inamandla abalaseleyo omatshini, i-thermal conductivity ephezulu kunye nokufakelwa kombane okulungileyo, okwenza ukuba ilungele uluhlu olubanzi lwezicelo. I-Aluminiyamu nitride, kwelinye icala, inika i-thermal conductivity egqwesileyo kunye neempawu zokwandisa i-thermal, iyenza ibe yinto efanelekileyo kwizicelo ezifuna ukuchithwa kobushushu ngokufanelekileyo.

2. Imikhondo yokuqhuba:

Iimpawu zokuqhuba zinoxanduva lokuthwala imiqondiso yombane phakathi kwamacandelo ahlukeneyo kwibhodi yesekethe. Kwiibhodi zeesekethe ze-ceramic, ii-conductor zetsimbi ezifana negolide, isilivere, okanye ubhedu zisetyenziselwa ukwenza le mikhondo. Ezi zinyithi zakhethwa ngenxa yombane ophezulu kunye nokuhambelana ne-ceramic substrates. Igolide ngokubanzi ithandwa ngenxa yokumelana nokugqwesa kwayo okugqwesileyo kunye neempawu ezizinzileyo zombane, ngakumbi kwizicelo ezisebenza ngamaza amaninzi.

3. Umaleko weDielectric:

Iingqimba zeDielectric zibalulekile ekukhuseleni imikhondo ye-conductive kunye nokuthintela ukuphazamiseka kwesignali kunye neesekethe ezimfutshane. Izinto eziqhelekileyo ze-dielectric ezisetyenziswa kwiibhodi zeesekethe ze-ceramic yiglasi. Iglasi ineempawu ezigqwesileyo zokugquma umbane kwaye inokubekwa njengomaleko obhityileyo kwiisubstrates zeceramic. Ukongezelela, i-glass layer inokwenziwa ngokwezifiso ukuba ibe nexabiso elithile le-dielectric rhoqo, livumela ukulawulwa ngokuchanekileyo kweempawu zombane zebhodi yesiphaluka.

4. Imaski yesoda kunye nonyango lomphezulu:

Imaski yeSolder isetyenziswa ngaphezulu kweetrayisi zokuqhuba ukuzikhusela kwizinto ezisingqongileyo ezinjengothuli, ukufuma, kunye ne-oxidation. Ezi maski zenziwe nge-epoxy okanye i-polyurethane-based materials ezibonelela ngokugquma kunye nokhuseleko. Sebenzisa unyango olungaphezulu olufana netoti yokuntywiliselwa okanye iplating yegolide ukuqinisa ukuthengiseka kwebhodi kunye nokuthintela i-oxidation yemithamo yobhedu evezwayo.

5. Ngokuzalisa imathiriyeli :

I-Vias yimingxuma emincinci egrunjwa ngebhodi yesekethe evumela uqhagamshelo lombane phakathi kwamaleko ahlukeneyo ebhodi. Kwiibhodi zeesekethe ze-ceramic, ngokusebenzisa izinto zokuzalisa zisetyenziselwa ukuzalisa le mingxuma kunye nokuqinisekisa ukuhanjiswa kombane okuthembekileyo. Okuqhelekileyo ngokusebenzisa izinto zokuzalisa ziquka iipasti eziqhubayo okanye iifayili ezenziwe ngesilivere, ubhedu okanye ezinye iincinci zetsimbi, ezixutywe ngeglasi okanye iifayili ze-ceramic. Olu luhlu lubonelela ngokuzinza kombane kunye noomatshini, ukuqinisekisa uxhulumaniso oluqinileyo phakathi kwemigangatho eyahlukeneyo.

Isishwankathelo

Ukuveliswa kweebhodi zeesekethe ze-ceramic kubandakanya ukudibanisa izinto ze-ceramic, isinyithi kunye nezinye izinto ezikhethekileyo. I-aluminiyam oxide kunye ne-aluminiyam nitride zisetyenziswa njenge-substrates, ngelixa isinyithi esifana negolide, isilivere kunye nobhedu zisetyenziselwa imikhondo yokuhambisa. Iglasi isebenza njengesixhobo se-dielectric, ebonelela ngokufakelwa kombane, kunye ne-epoxy okanye i-polyurethane solder imaski ikhusela umkhondo wokuqhuba. Uxhulumaniso phakathi koluhlu oluhlukeneyo lusekwe ngokuzaliswa kwezinto ezibandakanya i-conductor paste kunye nezizaliso.

Ukuqonda izinto ezisetyenziselwa ukuveliswa kweebhodi zeesekethe ze-ceramic kubalulekile kwiinjineli kunye nabayili ukuphuhlisa izixhobo zombane ezisebenzayo nezithembekileyo. Ukukhetha izinto ezifanelekileyo kuxhomekeke kwiimfuno ezithile zesicelo ezifana ne-thermal conductivity, izakhiwo zombane kunye neemeko zokusingqongileyo. Ngokusebenzisa iipropathi ezizodwa zemathiriyeli nganye, iibhodi zeesekethe ze-ceramic ziyaqhubeka nokuguqula amashishini ahlukeneyo ngokusebenza kwawo okuphezulu kunye nokuqina.
