Itheminali yokufaka i-eye-of-the-needle (EON), eklanyelwe ukufaka esikhundleni samatheminali athengisiwe kumabhodi esekethe aphrintiwe, ibilokhu ikhiqizwa emakethe isikhathi esingaphezu kweshumi leminyaka ngezinguqulo ezingu-0.64mm nezingu-0.81mm.
Isebenza kanjani i-Press-fit
I-EON press-fit zone iphawuleka ngokuqinisekisa ukuxhumana okuthembekile phakathi kwetheminali kanye ne-plated-through-hole (PTH) yebhodi lesekethe ephrintiwe (PCB) ngaphansi kwezinhlelo zokusebenza ezinzima zezimoto.Lezi zinhlelo zokusebenza zifaka phakathi izinga lokushisa lokuhamba ngebhayisikili ukusuka ku -40ᴼC ukuya ku-175ᴼC, umswakama ophezulu, ukushisa okomile, nokudlidliza kanye nobunzima obuhlobene nezimo zemoto.
Isihluthulelo sokuthola ukwethembeka ngaphansi kwalezi zimo ukwakheka kwesivalo esibamba igesi kusixhumi esibonakalayo phakathi kwendawo ethobelayo yetheminali kanye nembobo epuletiwe.Isixhumi esibonakalayo sokuxhumana sivalwe ngokoqobo endaweni ezungezile kuze kube yilapho kungangeneki khona ngenxa yomswakama ophezulu noma izinto ezingcolisa igesi, futhi ngaleyo ndlela akutholakali ekwakhekeni kwama-oxide angaphezulu.Ama-oksidi anesibopho sokubangela ukumelana okuphezulu kokuxhumana, okungase kuholele ekungazinzini kwesistimu futhi mhlawumbe nokwehluleka kwesistimu.
I-gas-tight seal igcinwa amandla ajwayelekile aphezulu asukela ku-25,000g.0.81mm cindezela-ilingane ukuze azungeze u-4,000g ngo-0.40mm ukucindezela-fit.(Amawashi alingana nokucindezela okungu-0.64mm cishe ku-8,000g.) [Wonke amandla avamile acashuniwe awosayizi be-PTH, kanye namasistimu kathini.] Lawa amandla avamile aphezulu kakhulu, uma eqhathaniswa namandla avamile aphakathi kuka-100g no-200g isistimu yokuxhumana ye-blade-receptacle ejwayelekile.
I-0.4mm Press-fit
Indawo entsha ye-press-fit engu-0.4mm EON yakhelwe ukuthi isebenze nosayizi ojwayelekile manje womkhakha ocwecwe ngembobo ongu-0.60±0.05mm.I-press-fit zone ifinyelela amandla okugcina asezingeni eliphezulu ekugcineni ngakunye kwebanga losayizi we-PTH ngokusebenzisa inhlanganisela yokuguquguquka okunwebekayo nokwepulasitiki, okuchemile kowakuqala ekugcineni okuphansi kosayizi we-PTH, futhi kuya kokugcina phezulu. ukuphela kobubanzi besayizi ye-PTH.Akukho ndawo lapho ubude buvunyelwe ukweqa umkhawulo wezinto ezibonakalayo, ukuqeda amathuba okwakheka kwe-micro-crack.
Izinto ezilinganiswe ngokucindezela ngokulinganayo ku-CuNiSi (C19010) esebenza kakhulu, kodwa zizohlinzeka nge-CuSn4 ne-CuSn6 uma kudingeka.Ukwengeza, itheminali izonikezwa ngokufakwa okusansimbi okujwayelekile nokuncishisiwe.Lesi sakamuva sisebenza ikakhulukazi ekusetshenzisweni kwetheminali ephezulu kakhulu ukuze kuncishiswe amathuba okushaya amathini.
