Emkhakheni we-electronics, amabhodi esekethe adlala indima ebalulekile ekuxhumaniseni izingxenye ezihlukahlukene nokuqinisekisa ukusebenza kahle kwedivayisi. Ngokuhamba kweminyaka, intuthuko kwezobuchwepheshe iholele ekuthuthukisweni kwemiklamo yebhodi yesifunda eyinkimbinkimbi futhi ehlangene. Enye yentuthuko enjalo ukwethulwa kwamabhodi esekethe we-HDI (High Density Interconnect).Kulokhu okuthunyelwe kwebhulogi, sizohlola umehluko phakathi kwamabhodi wesekethe we-HDI namabhodi avamile e-PCB (Ibhodi Lesifunda Eliphrintiwe).
Ngaphambi kokuhlolisisa okuqukethwe okuthile, masiqale siqonde imiqondo eyisisekelo yamabhodi esekethe e-HDI namabhodi e-PCB.I-PCB iyipuleti eliyisicaba elenziwe ngezinto ezingaphenduki elinemizila ye-conductive efakwe kulo. Lezi zindlela, ezibizwa nangokuthi imikhondo, zinesibopho sokuthwala amasignali kagesi phakathi kwezingxenye ezahlukene ebhodini lesifunda. Amabhodi e-PCB asetshenziswa kakhulu ezintweni ezihlukene zikagesi, kusukela kuma-smartphones nama-laptops kuya emishinini yezokwelapha nezinhlelo zezimoto.
Amabhodi e-HDI, ngakolunye uhlangothi, ayizinguqulo ezithuthuke kakhulu zamabhodi e-PCB.Ubuchwepheshe be-HDI buvumela ukuminyana kwesekethe okuphezulu, imigqa emincane, nezinto ezisetshenziswayo ezizacile. Lokhu kwenza ukuthi kukhiqizwe amadivaysi kagesi amancane, alula futhi aqine kakhulu. Amabhodi esekethe e-HDI ngokuvamile asetshenziswa ezinhlelweni ezidinga isivinini esiphezulu, ukusebenza okungcono, nokwenza kancane, njengama-smartphones asezingeni eliphezulu, amaphilisi, nezisetshenziswa ze-aerospace.
Manje ake sibheke umehluko phakathi kwamabhodi wesekethe we-HDI namabhodi ajwayelekile e-PCB:
Ukuminyana Kwesekethe nokuba yinkimbinkimbi:
Isici esiyinhloko esihlukanisayo phakathi kwamabhodi wesifunda se-HDI namabhodi we-PCB avamile ukuminyana kwesifunda. Amabhodi e-HDI anomthamo wesifunda ophakeme kakhulu ngenxa yamasu awo okukhiqiza athuthukile kanye nemithetho yokuklama ekhethekile. Uma kuqhathaniswa namabhodi e-PCB endabuko, avame ukuba nezendlalelo ezimbalwa, amabhodi e-HDI ngokuvamile anezendlalelo eziningi, kusukela ku-4 kuya kwezingu-20. Bavumela ukusetshenziswa kwezendlalelo ezengeziwe kanye nama-vias amancane, okuvumela izingxenye eziningi ukuthi zihlanganiswe endaweni encane. Ngakolunye uhlangothi, amabhodi e-PCB ajwayelekile anqunyelwe ukwakheka kwawo okulula kanye nezendlalelo ezimbalwa, okuholela ekunciphiseni kokuminyana kwesekethe.
Ubuchwepheshe be-Micropore:
Amabhodi esekethe e-HDI asebenzisa kakhulu ubuchwepheshe be-microvia, okuhlanganisa ama-vias ayimpumputhe, ama-vias angcwatshwe kanye nama-vias astakiwe. Lezi zindlela zinikeza ukuxhumana okuqondile phakathi kwezendlalelo ezihlukene, ukunciphisa indawo engaphezulu edingekayo ukuze kusetshenziswe umzila nokwandisa isikhala esitholakalayo. Ngokuphambene, amabhodi e-PCB ajwayelekile avame ukuthembela kubuchwepheshe be- through-hole, obukhawulela ikhono lawo lokufinyelela ukuminyana kwesekethe, ikakhulukazi kumiklamo yezendlalelo eziningi.
Ukuthuthuka kwezinto zokwakha:
Amabhodi esekethe e-HDI ngokuvamile afaka izinto ezisetshenziswayo ezinezimo ezithuthukisiwe ezishisayo, zikagesi, nezomshini. Lezi zinto zinikeza ukusebenza okuthuthukisiwe, ukuthembeka nokuqina, okwenza amabhodi e-HDI afanele izicelo ezifunayo. Amabhodi e-PCB avamile, ngenkathi esasebenza, ngokuvamile asebenzisa izinto eziyisisekelo futhi angase angahlangabezani nezidingo eziqinile zemishini kagesi eyinkimbinkimbi.
I-Miniaturization:
Amabhodi esekethe e-HDI aklanyelwe ukuhlangabezana nezidingo ezikhulayo ze-miniaturization zamadivayisi kagesi. Izindlela zokukhiqiza ezithuthukisiwe ezisetshenziswa kumabhodi we-HDI zivumela ama-vias amancane (izimbobo ezixhuma izingqimba ezihlukene) kanye nokulandela okucolekile. Lokhu kubangela ukuminyana okuphezulu kwezingxenye endaweni yeyunithi ngayinye, okuvumela ukukhiqizwa kwamadivayisi amancane, ashelelezi ngaphandle kokuphazamisa ukusebenza.
Ubuqotho besignali nezinhlelo zokusebenza ezinesivinini esikhulu:
Njengoba isidingo sokusheshisa ukudluliswa kwedatha nobuqotho besignali ephakeme siqhubeka sikhula, amabhodi wesifunda se-HDI anikeza izinzuzo ezibalulekile ngaphezu kwamabhodi e-PCB avamile. Ukuncishiswa nokulandelela osayizi kumabhodi we-HDI kunciphisa ukulahleka kwesignali kanye nokuphazamiseka komsindo, okuwenza afanelekele izinhlelo zokusebenza ezinesivinini esikhulu. Ubuchwepheshe be-HDI buphinde buvumele ukuhlanganiswa kwezici ezengeziwe ezifana ne-vias eyimpumputhe nengcwatshiwe, okuqhubekisela phambili ukuthuthukisa ukusebenza kwesignali nokwethembeka.
Izindleko zokukhiqiza:
Kuyaphawuleka ukuthi izindleko zokukhiqiza zamabhodi wesifunda we-HDI ngokuvamile ziphezulu uma ziqhathaniswa namabhodi e-PCB ajwayelekile. Ukwanda kobunzima kanye nenani lezingqimba kwenza inqubo yokukhiqiza ibe yinkimbinkimbi futhi idle isikhathi. Ukwengeza, ukusetshenziswa kwezinto eziphambili kanye nemishini ekhethekile kunezela ezindlekweni zizonke. Kodwa-ke, izinzuzo nokuthuthukiswa kokusebenza okunikezwa amabhodi we-HDI kuvame ukudlula izindleko zabo eziphakeme, ikakhulukazi ezimbonini lapho ukwethembeka okuphezulu kanye nokwenza okuncane kubaluleke kakhulu.
Izicelo kanye nezinzuzo:
Ukusetshenziswa kwebhodi lesifunda le-HDI:
Amabhodi e-HDI asetshenziswa kakhulu kumishini kagesi ehlangene njengama-smartphone, amaphilisi, izinto ezigqokwayo, namadivayisi amancane ezokwelapha. Ikhono lazo lokusekela ukusebenza okuthuthukile kanye nezici zefomu ezinciphayo lizenza zifanelekele lezi zinhlelo zokusebenza.
Izinzuzo zamabhodi wesifunda we-HDI:
- Ukuminyana kwesekethe okukhulu kuvumela imiklamo eyinkimbinkimbi futhi enothile ngesici.
- Ubuqotho besignali obuthuthukisiwe ngenxa yokuncipha kwe-parasitic capacitance kanye ne-inductance.
- Ukukhipha ukushisa okuthuthukisiwe kuqinisekisa ukusebenza kahle kwezingxenye zamandla aphezulu.
- Iphrofayela encane yonga isikhala futhi isekela ukwakheka okungasindi.
- Ukumelana okuthuthukisiwe kokushaqeka, ukudlidliza kanye nezici zemvelo, ukuthuthukisa ukuthembeka okuphelele kwemishini.
Ngamafuphi,umehluko phakathi kwamabhodi wesifunda se-HDI namabhodi we-PCB ajwayelekile mkhulu. Amabhodi wesekethe we-HDI anikeza ukuminyana kwesekethe okuphakeme, amasu okukhiqiza athuthukile kanye nezinzuzo zesignali yobuqotho, okuwenza alungele ukusebenza okuphezulu, amadivaysi kagesi ahlangene. Kodwa-ke, amabhodi e-PCB ajwayelekile angaphinda asebenze ezinhlelweni ezingadingi ubunzima obuphezulu noma ukwenza okuncane. Ukuqonda lo mehluko kuzokwenza abaklami nabakhiqizi bakwazi ukukhetha ibhodi lesifunda elifanelekile ngezidingo zabo ezithile, ukuqinisekisa ukusebenza kahle, ukwethembeka kanye nokusebenza kwemishini yabo kagesi.
