Abstract-A press-fit connector for automobile airbag electronic
tswj units (ECUs) tau tsim thiab xa mus rau pawgntau lawm theem los ntawm Sumitomo Wiring Systems, Ltd. thiabAutoNetworks Technologies, Ltd. hauv 2005.
Kev sib txuas xovxwm yog ib qho kev sib txuas hluav taws xob uas tsis muaj hluav taws xobtechnology, uas siv cov neeg kho tshuab kev sib cuag quab yuam generatednruab nrab ntawm-qhov ntawm cov ntawv luam tawm Circuit Board (PCB) thiabterminals nrog ib tug dav me ntsis loj dua li ntawm lub qhovtxoj kab uas hla.
Cov cuab yeej no tau pom dav dav tsis ntev los no raws li kev ntsuastiv thaiv "Lead Free Requirement" ntawm cov ntaub ntawv suav nrogcov khoom siv hluav taws xob / hluav taws xob.
Rau kev siv cov thev naus laus zis no rau cov tsheb sib txuas,peb yuav tsum coj mus rau hauv tus account qhov hnyav dua ib puag ncigyam yuav tsum tau muaj.
Yog li ntawd, ib lub xovxwm-haum connector rau tsheb airbag ECUstau ntse tsim thiab loj-tsim los ntawm 2005.
Tsis tas li ntawd, cov kws sau ntawv kuj tau tsim ib hom tshiab nyuajtin plating ntawm terminals, yog li tiv thaiv lub scraping-tawm ntawm tinThaum lub sij hawm txheej txheem insertion, uas yuav ua rau ib tug luv luv-circuitntawm PCB.

A. Lead Free Requirement and Press-fit Connection
Muaj kev nyiam thoob ntiaj teb mus rau kev tshem tawm kev phom sij
cov ntaub ntawv los ntawm cov khoom siv hluav taws xob / hluav taws xob (ex. RoHSCov lus qhia [1]).Hauv particular, txoj kev loj hlob ntawm txhuas dawb solderyog qhov tseem ceeb tshaj plaws rau kev lag luam hluav taws xob / hluav taws xobthoob ntiaj teb.
Ntawm qhov tod tes, nyob rau hauv cheeb tsam ntawm automotive electronicstswj units (ECUs), muaj kev txaus siab rau solderless xovxwm-haumkev sib txuas tshuab rau mounting ho-qhov insertion homqhov chaw, zoo li connectors, uas yav tas los ua tiav los ntawm antws los yog yoj soldering txheej txheem.
Txawm hais tias cov cuab yeej no tau txais kev pom zoonyob rau hauv cheeb tsam ntawm cov khoom siv sib txuas lus hauv ob peb lub dhau los
Ntau xyoo lawm, muaj ntau qhov kev cia siab ntawm lawv daim ntawv thov hauv tsheb sib txuas, tsis ntev los no yuav raug ntsuas los tswj cov kev cai tsis pub dawb.
Kev sib txuas xovxwm yog ib hom kev sib txuas ntawm cov tshuab hluav taws xob, uas siv cov cuab yeej sib txuas uas tsim los ntawm lub qhov ntawm lub rooj tsavxwm luam tawm (PCB) thiab cov terminals uas muaj qhov dav me ntsis loj dua li ntawm lub qhov taub, raws li qhia hauv daim duab. .1.
Cov thev naus laus zis no kuj muaj qhov zoo ntxiv ntawm (I) Tsis muaj cov txheej txheem cua sov ntxiv rau cov khoom siv saum npoo av, (2) Tsis tas yuav siv cov khoom siv hluav taws xob tiv thaiv hluav taws xob rau cov vaj tsev sib txuas, vim tias cov txheej txheem nkag ntawm lub davhlau ya nyob twg (piv txwv li nias-haum txuas) yog ua ntawm chav ntsuas kub tau piav qhia hauv Table I.
