Isidingo Sokuxhumanisa Okuzenzakalelayo-okulungele I-Solderless
Ukudala izixazululo ze-interconnect ebhodini kuyindawo enenselelo enkulu yokuqaliswa kwezinqubo zokudambisa ezingenamthofu.Indawo eyodwa ebalulekile yabakhiqizi bevolumu ephezulu ukugcina ukusebenza kahle kokukhiqiza sekukonke.Izinqubo zokudambisa zesibili ebezidingeka ngokwesiko ukuze kuxhunywe izixhumi ezinkulu nezinye izixhumi ezikhethekile zinzima kakhulu ukuziguqulela kuzinqubo ezingenamthofu.Lokhu kuyinselele ikakhulukazi kuma-PCB ethusi esindayo njengama-interconnects.
Izikhonkwane ze-Press-fit (ezihambisanayo) sezineminyaka engaphezu kwengu-20 zikhona, zisetshenziswa kabanzi ezimakethe ezimbalwa ezihlosiwe.Ubuchwepheshe be-Press-fit (obuthobelanayo) buhlanganisa idizayini ekhethekile yesigaba sokufakwa kwephinikhodi ngayinye, enikeza isixhumi esibonakalayo esiqinile nesithembekile esibamba igesi ngembobo ecwecwe futhi engadingi isinyathelo sokunamathisela esilandelayo.
Ingxenye yokushutheka yephinikhodi inkulu kunobubanzi bembobo kodwa yakhelwe ukonakala ngesikhathi sokufakwa, okudala ukungqubuzana okuqinile phakathi kwephinikhodi nendawo egqinsiwe.
I-Eye-of-the-needle Design
Ngokuhamba kweminyaka, kuye kwasetshenziswa izindlela eziningana zokuklama ukuze kuhlinzekwe ukulingana okuqinile okudingekayo kumaphini athobelayo.Njengoba ubuchwepheshe be-press-fit (obuthobelanayo) buthuthela ezinhlelweni ezintsha ezifana ne-Smart Junction Boxes, embonini yezimoto, kubalulekile ukuthi amandla phakathi kwephini kanye nendawo egqinsiwe ehlala anele ukumelana nezici zemvelo nezomshini ezifana nokushisa, umswakama, ukudlidliza, ukushaqeka nezinye izimo ezimangelengele ezitholakala endaweni yemoto.
Indlela "yeso-yenaliti" ifakazelwe ukuthi ihlinzeka ngobuchwepheshe obuthembeke kakhulu bokuthuthukisa amandla okugcina okuqala naqhubekayo.Idizayini efana nentwasahlobo esetshenziswa ekucushweni kweso lenaliti inikeza amandla okuxhumana esikhathi eside ngokumelene nombhobho wembobo.
Izinga lokushisa elisebenzayo kuwo wonke amaphini ngu -40 kuya ku-125 C, futhi angakwazi ukumelana no-125 C amahora angu-1,008.Izikhonkwane ze-engeli yesokudla (umugqa owodwa nokabili) ayatholakala futhi ukuze ajoyine ama-PCB ancikene.Yonke imikhiqizo inikezwa nge-RoHS-lead-free plating.
Izixhumi zibunjwe ngepulasitiki eqinile enezinhlobonhlobo zezikhonkwane.Angase abe nezikhonkwane ezimbalwa ezifika ku-3, nezikhonkwane ezingaba ngu-256.”: kusho i-Assembly Magazine esihlokweni sayo esikhuluma ngezixhumi ze-Press-fit kanye nezinzuzo zazo.
Ikhono Lamanje Lokuthwala
Amatheminali e-Press-fit (athobelayo) anomthamo wamanje omuhle kakhulu futhi angasiza ikakhulukazi ekuxhumekeni kwamandla kumabhodi ethusi esindayo, okungaba nzima ukuwathengisa ngakho-ke kuba nzima kakhulu ukushintshela ezindaweni ezingenamthofu.Esikhundleni sokulungisa noma ukulungisa amapharamitha wenqubo yokugeleza kabusha ukuze kuhlangatshezwane nezinselele ezikhethekile zokudambisa ama-PCB ethusi esindayo, abakhiqizi bangasungula amafasitela okulawula inqubo evamile futhi basuse izidingo ezikhethekile zokudambisa ngokusebenzisa ukuxhuma okuhambisanayo kwezinhlelo zokusebenza zamanje.
Ihlolelwe ukwethembeka, amandla okugcina kanye nokumelana nemvelo
Ubuchwepheshe bohlobo lwe-eye-of-the-needle Press-fit (obuthobelanayo) buhlolwe kabanzi ukuze kuqinisekiswe ukuthobelana nenani lezidingo ezibalulekile zemboni, okuhlanganisa i-SAE/USCAR-2, Rev4, EIA Publication 364 kanye ne-IEC 60352-5 imininingwane.Inqubo yokuhlola isebenzise ukuhlola okuhlelekile kwezinto zemvelo, ezomshini kanye nokwethembeka ngaphansi kwezimo ezilawulwayo.
Ukuhlolwa kwenzelwe uhla lwezixhumi ezihlukene ze-Press-fit (ezihambisanayo) nezinhlobo ze-PCB (okuhlanganisa nokucwecwa kwethusi, ukucwebezeliswa kwegolide nokuqedwa kwe-HASL).Wonke amasampula okuhlola akhiwe futhi ahlanganiswa kusetshenziswa amasu okukhiqiza avamile kanye nemibandela yekhwalithi.
Ukuhlola okukhethekile kufaka phakathi ukudlidliza, ukushaqeka okushisayo nempilo eshisayo, ukushaqeka komshini, amandla okufaka, amandla okugcina, umswakama, ukuhamba ngebhayisikili kwamanje kanye nokumelana nokuxhumana.Yonke imiklamo ye-interconnect idlula ngokuqhubekayo ngaphandle kokulimala kanye/noma ukuhambisana nemingcele ethile.
Ukucaciswa Kwephinikhodi Ethobelayo, Ukucushwa, Izinketho
Izixhumi ze-Press-fit (ezihambisanayo) ziyatholakala ekucushweni okulandelayo:
Amatheminali ahlukene (ama-blades, amathebhu, njll.)
Izikhonkwane ezine-reeled eziqhubekayo
Cindezela-linganisa izihloko kumareli aqhubekayo noma ubude bokusika ngaphambilini (ngokukodwa noma okubili ngakubili)
Isikwele noma esiyindilinga (izinga lemboni noma ububanzi bangokwezifiso nobude bephini)
