Lub qhov muag-of-the-needle (EON) xovxwm-haum davhlau ya nyob twg, uas yog tsim los hloov cov terminals soldered nyob rau hauv Circuit Court boards, tau nyob rau hauv ntau lawm nyob rau hauv kev ua lag luam rau ntau tshaj kaum xyoo nyob rau hauv 0.64mm thiab 0.81mm versions.
Yuav ua li cas nias-fit ua haujlwm
EON xovxwm-haum cheeb tsam yog qhov tseem ceeb rau kev ua kom ntseeg tau kev sib txuas ntawm lub davhlau ya nyob twg thiab plated-dhau-qhov (PTH) ntawm lub rooj tsavxwm luam tawm (PCB) raws li kev siv tsheb loj.Cov ntawv thov no suav nrog kev caij tsheb kauj vab kub los ntawm -40ᴼC txog 175C, cov av noo siab, qhuav cua sov, thiab kev co thiab hnyav uas cuam tshuam nrog lub tsheb sprung.
Tus yuam sij kom ua tiav kev ntseeg siab nyob rau hauv cov xwm txheej no yog tsim cov roj-nruj foob ntawm qhov sib cuam tshuam ntawm thaj tsam ntawm lub davhlau ya nyob twg thiab plated-dhau-qhov.Qhov kev sib txuas lus tau raug kaw los ntawm ib puag ncig ib puag ncig mus rau qhov uas nws yog impenetrable los ntawm high humidity los yog corrosive pa pa phem, thiab yog li tsis muaj nyob rau tsim ntawm nto oxides.Oxides yog lub luag haujlwm ua rau muaj kev tiv thaiv siab, uas tuaj yeem ua rau lub cev tsis ruaj khov thiab ua rau lub cev tsis ua haujlwm.
Gas-tight seal yog tswj los ntawm lub zog ib txwm muaj nyob ntawm thaj tsam ntawm 25,000g.0.81mm nias-haum rau ib ncig ntawm 4,000g rau 0.40mm xovxwm-haum.(Lub 0.64mm xovxwm-haum moos nyob ib ncig ntawm 8,000g.) [Tag nrho cov quoted ib txwm rog yog rau nominal PTH qhov ntau thiab tsawg, thiab rau tin systems.] Cov no yog cov tsis tshua muaj siab ib txwm rog, thaum piv nrog ib txwm rog ntawm 100g thiab 200g rau ib tug raug hniav-receptacle tin contact system.
Lub 0.4mm Press-fit
Tag nrho-tshiab 0.4mm EON xovxwm-haum zone yog tsim los ua haujlwm nrog tam sim no kev lag luam-tus qauv plated-los ntawm-qhov loj ntawm 0.60 ± 0.05mm.Lub cheeb tsam xovxwm ua tiav qhov zoo tshaj plaws tuav lub zog ntawm txhua qhov kawg ntawm PTH qhov loj me los ntawm kev ua haujlwm ntawm kev sib xyaw ua ke ntawm elastic thiab yas deformation, uas yog kev sib tw rau yav dhau los ntawm qis kawg ntawm PTH qhov loj me, thiab mus rau tom kawg ntawm qhov siab dua. kawg ntawm PTH qhov loj me.Tsis muaj qhov taw tes yog qhov elongation tso cai kom dhau cov khoom txwv, kom tshem tawm qhov tshwm sim ntawm micro-crack tsim.
Standardized xovxwm-haum cov ntaub ntawv rau cov high-kev ua tau zoo CuNiSi (C19010), tab sis yuav muab CuSn4 thiab CuSn6 yog tias xav tau.Tsis tas li ntawd, lub davhlau ya nyob twg yuav muab rau hauv tus qauv thiab txo cov tin plating.Cov yav tas yog tshwj xeeb tshaj yog muaj feem xyuam rau hauv high-density davhlau ya nyob twg daim ntawv thov kom txo tau cov tin whiskering.
