Asebenza Kanjani Amabhodi Wesekethe

Amabhodi esekethe, ajwayele ukubizwa ngokuthi Amabhodi Esifunda Aphrintiwe (PCBs), ayizici eziyisisekelo kumishini yesimanje kagesi. Lawa mabhodi asebenza njengezinkundla ezibonakalayo lapho izingxenye ze-elekthronikhi ezihlukahlukene zifakwa futhi zixhunywe khona. Empeleni, zakha 'ubuchopho' bazo zonke izisetshenziswa zika-elekthronikhi, okwenza ukuhlanganiswa kwezingxenye ezihlukene kusebenze ndawonye ngaphandle komthungo. Kusukela kumagajethi ansuku zonke afana nama-smartphones namakhompuyutha kuya kumasistimu ayinkimbinkimbi ezimbonini zezimoto nezomkhathi, amabhodi esekethe abalulekile ekuhlinzekeni ngengqalasizinda edingekayo yokuxhumana nogesi nokusebenza.

Isakhiwo Esiyisisekelo Sebhodi Lesekethe

Isakhiwo sebhodi lesifunda sibalulekile ekusebenzeni kwalo. Emgogodleni wayo i-substrate, ngokuvamile eyenziwe ngezinto ezifana ne-fiberglass, ehlinzeka ngosekelo lwemishini. Kule substrate, imikhondo yethusi eqhutshwayo ibhalwe ukuze kwakhiwe izindlela zamasignali kagesi. Lezi zindlela zixhuma izingxenye ezihlukahlukene ebhodini, zivumela ukuthi zixhumane futhi zisebenze ngazwi linye. Ukwengeza, amabhodi esekethe angase abe nezendlalelo eziningi, ikakhulukazi kuma-elekthronikhi ayinkimbinkimbi, anezendlalelo zangaphakathi zokusabalalisa amandla kanye nomzila wesignali. Idizayini yalezi zinsalela nezendlalelo ihlelwe ngokucophelela ukuze kuqinisekiswe ukusebenza kahle komshini kagesi.

Izingxenye Ezibalulekile Ebhodini Lesekethe

resistors

Ama-resistors alawula ukugeleza kwamandla kagesi ngaphakathi kwesekhethi, avimbele ukulimala ezingxenyeni ezibucayi ngokukhawulela i-current.

Capacitors

Ama-Capacitor agcina futhi akhulule amandla kagesi, esiza ukuzinzisa amandla kagesi kanye nokunikezwa kwamandla ngaphakathi kwesekhethi.

Izifunda Ezihlanganisiwe (ICs)

Ama-IC, aziwa nangokuthi ama-microchips, ayiziyingi eziyinkimbinkimbi ezenziwe zafakwa ku-chip encane. Bangenza imisebenzi ehlukahlukene, kuye ngomklamo wabo, kusukela ekucubunguleni idatha kuya ekukhuliseni amasignali.

Ama-Diodes nama-Transistors

Ama-Diode avumela ukugeleza kwamanje ohlangothini olulodwa kuphela, kuyilapho ama-transistors enza njengamaswishi noma ama-amplifiers kusekethe.

Izixhumi namasokhethi

Lezi zingxenye zisetshenziselwa ukuxhuma ibhodi lesifunda kumadivayisi angaphandle noma imithombo yamandla.

Indlela Amabhodi Wesifunda Ugesi

Amabhodi esekethe asebenza njengemigudu kagesi emishinini kagesi. Imikhondo yethusi ekhonjiswa ebhodini idala izindlela eziqondisa amaza kagesi. Lezi zindlela zenzelwe ngokucophelela ukuxhuma izingxenye ezihlukahlukene ezifana nezimbangi, ama-capacitor, nama-microchips ngendlela ethile nangendlela ethile. Lokhu kugeleza kukagesi okuhlelekile yikho okuvumela ibhodi lesifunda ukuthi lenze imisebenzi eyinkimbinkimbi, kusukela ekucubunguleni idatha kukhompyutha ukuya ekulawuleni i-microwave ekhishini lakho. Empeleni, ibhodi lesifunda liqinisekisa ukuthi ugesi ufinyelela izingxenye ezifanele ngesikhathi esifanele, okwenza idivayisi isebenze ngendlela ehlosiwe.

Inqubo Yokudala Ibhodi Lesekethe

Idizayini nokuhlelwa

Isinyathelo sokuqala ukuklama isakhiwo sebhodi lesifunda usebenzisa isofthiwe ye-CAD. Lokhu kuhlanganisa ukubeka izingxenye kanye nemikhondo yomzila ukuze kwakhe ukuxhunywa kukagesi.

Ukukhiqiza Ibhodi

Umklamo ube usudluliselwa ku-substrate ye-copper-clad, bese ithusi elingadingeki liqoshwa ukuze kudaleke imikhondo. Izendlalelo eziningi zingase zenziwe i-laminated ndawonye esimweni samabhodi we-multilayer.

Umhlangano Wengxenye

Izingxenye ze-elekthronikhi zigxunyekwa ebhodini, kungaba ngobuchwepheshe be-surface-mount technology (SMT) noma ubuchwepheshe be- through-hole, kuye ngedizayini.

Ukuhlola Nokuqinisekisa Ikhwalithi

Ekugcineni, ibhodi lesifunda eliqediwe lihlolelwa ukusebenza kanye nekhwalithi, liqinisekisa ukuthi lihlangabezana nakho konke ukucaciswa komklamo.

Amabhodi esekethe abalulekile kuma-electronics esimanje, aklanywe ngobunyoninco ukuphatha nokuqondisa imisinga kagesi ukuze kusetshenziswe izinto zikagesi.

Izinhlobo zamabhodi wesekethe kanye nezicelo zawo

Kunezinhlobo eziningana zamabhodi wesifunda, ngalinye lenzelwe izinhlelo zokusebenza ezithile. Izinhlobo ezivame kakhulu zihlanganisa:

Ama-PCB Ongqimba Olulodwa

Lezi ziwuhlobo olulula kakhulu lwamabhodi wesifunda, anezingxenye ezifakwe ohlangothini olulodwa kanye nemikhondo yethusi ngakolunye. Asetshenziswa kakhulu kuma-electronics abathengi angabizi njengama-calculator nezinhlelo zokukhanyisa ze-LED.

Ama-PCB amaningi

Ama-PCB angama-Multilayer aqukethe izendlalelo eziningi ze-substrate nethusi, ezihlanganiswe ndawonye. Asetshenziswa kuma-elekthronikhi ayinkimbinkimbi njengama-smartphone, amaseva, nemishini yezimboni ngenxa yekhono lazo lokusekela amadizayini aphezulu kanye nokudluliswa kwesignali ngesivinini esikhulu.

I-Rigid-Flex PCBs

Ngokuhlanganisa ubuchwepheshe bebhodi eliqinile neliguquguqukayo, ama-PCB aqinile aklanyelwe izinhlelo zokusebenza ezidinga ukuqina nokuguquguquka, njengakumadivayisi ezokwelapha, amakhamera, kanye nezinsimbi zezindiza.

Kungani Idizayini Yebhodi Lesifunda Ibalulekile Ekusebenzeni Komkhiqizo

Ukuklanywa kwebhodi lesifunda kudlula izingxenye zokuxhuma; kuthinta ngokuqondile ukuthembeka kwedivayisi, ukusebenza, nempilo yokuphila. Idizayini ye-PCB engalungile ingaholela ekuphazamisekeni kwesignali, ukushisa ngokweqile, noma ngisho nokwehluleka okuphelele kwesistimu.

Isibonelo, ukulandelela okungalungile kungabangela ukonakala kwesignali kumasekhethi edijithali anesivinini esikhulu. Kugesi wamandla, ukushuba kwethusi okunganele noma ama-thermal angenamandla angaholela ezindaweni ezishisayo, kunciphise ukusebenza kahle nokuphepha komkhiqizo.

Ngakho-ke, ubunjiniyela bebhodi lesekethe ngokunaka ukwakheka, ukuphathwa kwezimo ezishisayo, nobuqotho besignali kubalulekile, ikakhulukazi ezinhlelweni ezibucayi zenjongo ezifana ne-aerospace, izimoto, kanye nemishini yezokwelapha.
