Izinketho Zama-elekhthronikhi Ukukhetha Kwekhwalithi Yokuziphatha Nokufaka I-Insulating
Kunokuthuthuka okuningi embonini ye-elekthronikhi ethuthuka usuku nosuku. Imikhiqizo kagesi yenziwe ngokunemba nokunemba ngonjiniyela abakhethekile. Kunezinto eziningi ezihlobene nokwenziwa komkhiqizo we-elekthronikhi. Izintambo, ama-windings, ama-resistor njll. Yizinto ezijwayelekile ezisetshenziswa ekulungiseleleni okokusebenza ngogesi. Kepha enye yezinto ebalulekile esetshenziswa kuzo zonke izinto zokusebenza unamathisela ngogesi. Lokhu kunamathisela ngogesi kwenziwa ngesiliva, i-aluminium nolunye uhlobo lwezakhi. Lawa ma-pastes ayashiswa futhi asetshenziselwe ukugcina uxhumano lwemishini yokuxhuma ngogesi / ukushisa / i-dielectric. Ama-pastes kagesi ayisidingo esibalulekile ezintweni ezisebenza ngogesi. Ukusetshenziswa kokunamathisela okuningi kungaholela ekujikelezeni okufushane futhi uma kusetshenziswe okuncane kunamathuba okuxhuma okungalungile. Kunezinhlobo eziningi zama-pastes atholakala emakethe. Umuntu kufanele aqinisekise ukuthatha ikhwalithi enhle yokunamathisela ukuqinisekisa ukuxhumana okuqinile.
Lezi zinamathisela zikagesi zisetshenziselwa ukuxhumana okushisayo noma kagesi ngemuva kokuzifudumeza ebhodini likagesi. Ngokuyinhloko lezi zinhlaka zingama-pastes esiliva ngoba isiliva linikeza inzuzo njengento ethambile, i-ductile, futhi ethambile kakhulu. Lezi zisetshenziswa kakhulu ku-soldering. Kunezinhlobo eziningi zokunamathisela ezitholakalayo ngokususelwa kuzakhiwo zazo zokuqhuba: -
* I-conductive paste - I-conductor paste iyingcina ehlanganisa ukuxhumana kukagesi ndawonye. Lezi zisetshenziswa kakhulu emabhodini lapho izintambo zingenzeki khona. Kunezinhlobo ezahlukahlukene zokunamathisela okuguquguqukayo okutholakala njenge-Ag paste, i-Ag/Pd paste, i-Au paste, i-Pt paste, i-wolfram paste engasetshenziswa ezinhlelweni ezahlukene ezifana ne-buzzer, i-electrode yensimbi engenasici, isekethe ye-ceramic eholelekile, isekethe yefilimu ewugqinsi kanye nokuzwa. ingxenye njll… Ngezinhlelo zokusebenza eziningi kangaka lezi zokunamathisela zidingeka kakhulu.
* I-resistor paste - I-resistor paste iwukutholwa okubaluleke kakhulu. Ilungiswa ngendlela yokuthi i-thermal conductive futhi ifakwe ngogesi. Isetshenziswa kakhulu njengesixhumi esibonakalayo se-heat sink nemithombo yokushisa. Ukwakhiwa okuyinhloko kwalawa ma-pastes yi-ag, pd kanye ne-RuO2. Ama-resistor paste asetshenziswa ku-chip resistor, resistor, substrate resistor kanye nenkundla yokushisa ephansi. Kunezigaba ezimbili zokunamathisela kwe-resistor: ukunamathisela kokumelana namandla kanye nokunamathisela kwefilimu ewugqinsi.
* I-Dielectric paste - I-dielectric paste ifakwe ngogesi futhi ingamelana nomthwalo we-voltage ephezulu. Ibuye isetshenziswe njenge-lubricant ngakho-ke ibizwa ngokuthi i-silicon grease. Lawa ma-paste asebenza ku-insulating yensimbi engagqwali, ebhodini lokushisisa lensimbi engenasici kanye nesekethe yefilimu ewugqinsi yefilimu enezingqimba eziningi.
* Ibhodi lokushisisa - Kunezinhlobonhlobo zamabhodi okushisa atholakalayo njengepuleti lokufudumeza le-ceramic, inguqulo yengilazi ye-ceramics yokufudumeza, ipuleti lokufudumeza lensimbi engagqwali kanye nepuleti lokufudumeza elithambile elingaphansi.
Lezi zimbumba zithole izicelo eziningi emisebenzini yokulungisa, indawo yokucwaninga kanye nokwakha izinto zokusebenza. Kukhona ochwepheshe abaningana abangochwepheshe abakha ikhwalithi enhle kakhulu ye-Ag unama. Ngamakhono athuthukisiwe nathuthukisayo laba ochwepheshe bavule ikhwalithi enhle kakhulu yokunamathisela ngogesi. Kule nkathi lapho ukusetshenziswa kwemishini kukhuliswe ngamandla kagesi, ukwenziwa kwalezi zinto zekhompiyutha kudinga izinto ezifakwa ngogesi.
