I-eye-of-the-needle (EON) i-terminal ye-press-fit terminal, eyenzelwe ukubuyisela ii-terminals ezithengiswayo kwiibhodi zesekethe eziprintiweyo, sele ikwimveliso kwimarike iminyaka engaphezu kweshumi kwiinguqulelo ze-0.64mm kunye ne-0.81mm.
Isebenza njani i-Press-fit
I-EON ye-press-fit zone iyaphawuleka ekuqinisekiseni uxhulumaniso oluthembekileyo phakathi kwe-terminal kunye ne-plated-through-hole (PTH) yebhodi yesekethe eprintiweyo (PCB) phantsi kwezicelo ezinzima zemoto.Ezi zicelo ziquka ukukhwela ibhayisekile kwiqondo lobushushu ukusuka -40ᴼC ukuya kwi-175ᴼC, ukufuma okuphezulu, ubushushu obomileyo, ukungcangcazela kunye nobunzima obunxulunyaniswa neemeko zokuphuma kwesithuthi.
Isitshixo ekufezekiseni ukuthembeka phantsi kwale miqathango kukubunjwa kwesitywina esiqinileyo segesi kwi-interface phakathi kwendawo ethobelayo ye-terminal kunye ne-plated-through-hole.Ujongano loqhagamshelwano luvalwe ngokoqobo ngaphandle kokusingqongileyo ukuya kuthi ga kwinqanaba lokungangeneki ngenxa yokufuma okuphezulu okanye izingcolisi zerhasi ezonakalisayo, kwaye ngaloo ndlela azifumaneki ekwenziweni kweeoksidi zomphezulu.Ii-oksidi zinoxanduva lokubangela ukuchasana okuphezulu koqhagamshelwano, okunokukhokelela ekungazinzini kwenkqubo kwaye mhlawumbi nokusilela kwenkqubo.
Isitywina esiqinileyo segesi sigcinwa ngamandla aqhelekileyo aphezulu asuka kwi-25,000g.I-0.81mm cinezela-ilungele ukujikeleza i-4,000g ye-0.40mm cinezela-fit.(Iiwotshi ze-0.64mm zokucinezela-fit malunga ne-8,000g.) [Zonke iiwotshi ezicatshuliweyo zezobukhulu obuqhelekileyo be-PTH, kunye neenkqubo zetoti.] La ngamandla aqhelekileyo aphezulu kakhulu, xa kuthelekiswa namandla aqhelekileyo aphakathi kwe-100g kunye ne-200g ye isixokelelwano senkcani esiqhelekileyo senkcenkce.
I-0.4mm Press-fit
Indawo entsha ye-0.4mm EON ye-press-fit zone yenzelwe ukusebenza kunye ne-industry-standard plated-through-hole size ye-0.60±0.05mm.Indawo yokucofa ifumana amandla okugcina awona wona makhulu ekupheleni koluhlu lwesayizi ye-PTH ngokusebenzisa indibaniselwano ye-elastic kunye ne-deformation yeplastiki, ethambekele kwicala langaphambili kwisiphelo esisezantsi soluhlu lwesayizi ye-PTH, kwaye ukuya ekugqibeleni kwindawo ephezulu. isiphelo soluhlu lobungakanani bePTH.Akukho ndawo i-elongation ivunyelwe ukuba idlule umda wezinto eziphathekayo, ukuphelisa ukukwazi ukubunjwa kwe-micro-crack.
Izinto ezisemgangathweni zokushicilela i-CuNiSi (C19010) ephezulu, kodwa iya kunika i-CuSn4 kunye ne-CuSn6 ukuba kuyimfuneko.Ukongeza, i-terminal iya kubonelelwa kumgangatho kunye nokunciphisa i-tin plating.Le yokugqibela ibaluleke kakhulu kwitheminali yoxinaniso oluphezulu ukunciphisa ukubakho kwe-whisking ye-tin.
