Yuav ua li cas los lav qhov kev ua tau zoo ntawm lub caij nplooj ntoos hlav-loaded Pogo Pin?
Lub caij nplooj ntoos hlav thimble muaj nuj nqis tseem ceeb heev thiab xwm txheej. Nws tseem yog ib feem tseem ceeb ntawm cov khoom siv hluav taws xob. Rau lub caij nplooj ntoos hlav thimble, yog tias koj xav muab kev ua si tag nrho rau nws qhov zoo thiab kev ua tau zoo, koj yuav tsum xyuas kom meej tias nws qhov zoo yog qhov zoo Thiab cov txheej txheem ntawm cov khoom sib txuas yog" xoom yuam kev", hauv lwm cov lus, nws yog ib qho tsim nyog los tiv thaiv kev ua haujlwm ntawm lub caij nplooj ntoos hlav thimble los ntawm kev puas tsuaj thaum lub sijhawm tsim khoom. Yog li, yuav ua li cas kom ntseeg tau qhov kev ua tau zoo ntawm pogo pins hauv kev tsim khoom? Tom ntej no, cov kws tshaj lij pogo pin manufacturers yuav piav qhia txog kev ua haujlwm tshwj xeeb rau txhua tus, thiab tom qab ntawd peb yuav saib ua ke.
Ua ntej, nrhiav lub caij nplooj ntoos hlav thimble
Thaum cov yas molten tsis tuaj yeem sau tag nrho cov me nyuam hauv plab, yuav muaj qee qhov" qhov dej ntws", uas feem ntau yog ib yam uas yuav tsum tau sim hauv theem txhaj tshuaj molding. Qhov teeb meem tuaj yeem pom los ntawm kev kuaj xyuas lub caij nplooj ntoos hlav thimble thiab nws qhov kev ua tau zoo tuaj yeem hloov kho. Kom paub meej tias yuav tsis muaj teeb meem. Thib ob, xyuas kom zoo ntawm pogo pins
Qhov thib ob, kom paub meej qhov zoo ntawm pogo pins
Raws li txhua tus paub, kev sib dhos khoom tiav yog theem kawg ntawm kev tsim khoom thiab tsim khoom ntawm lub caij nplooj ntoos hlav thimble connector, thiab nyob rau theem no, peb feem ntau siv electroplating los ua ke cov pins ib leeg, thiab lub hom phiaj yog los xyuas kom meej qhov zoo ntawm lub caij nplooj ntoos hlav thimble. .
Thib peb, tsim nyog tswj
Kev tswj kom tsim nyog yog ib txoj hauv kev zoo los saib xyuas kev tsim khoom. Hauv kev ua haujlwm tiag tiag, cov qauv no kuj tau lees paub qhov kev ncaj ncees ntawm cov khoom' qhov kev ua tau zoo thiab ua rau muaj kev paub zoo rau cov neeg siv khoom. Kuv ntseeg tias nws kuj yog ib hom Tswv Yim uas tsim nyog sim thiab siv. Tsis tas li ntawd, koj tuaj yeem nrhiav cov kws tshaj lij lub caij nplooj ntoos hlav thimble kom paub ntau ntxiv txog lub caij nplooj ntoos hlav thimble lossis yuav lub caij nplooj ntoos hlav thimble.
Nyob rau hauv cov ntsiab lus, nyob rau hauv cov txheej txheem ntau lawm, yog tias koj xav kom cov kev ua tau zoo ntawm lub caij nplooj ntoos hlav thimble, koj yuav tsum ua raws li cov txheej txheem uas tau piav nyob rau hauv tsab xov xwm. Cov txheej txheem no yog qhov ua tau zoo heev thiab tseem yog txoj hauv kev tseem ceeb los xyuas kom meej qhov kev ua tau zoo ntawm lub caij nplooj ntoos hlav thimble, yog li koj yuav tsum paub thiab siv tag nrho cov kev qhia hauv cov ntawv nyeem yog qhov tseem ceeb.
Cov nyhuv EMC ntawm cov khoom txuas tau nthuav dav
Lub connector yog ib qho khoom siv tsis pom kev hauv ntiaj teb, ib qho khoom siv uas tsis tau teev tseg raws li cov cuab yeej tswj xyuas tseem ceeb los ntawm lub koom haum tswj hwm, ib qho khoom siv tsis tseem ceeb hauv txhua yam khoom siv hluav taws xob thiab hluav taws xob, tab sis nws cov khoom siv hluav taws xob sib raug zoo (xws li EMC) rau cov khoom siv ntau lawm. los yog system Cov cawv ntawm) tsis tuaj yeem tsis quav ntsej.
Thaum xaiv ob peb lub connector, lub zog qaug zog nyob rau hauv lub vibration xeev tsis tau txiav txim siab. Kev txuas txuas txuas ntxiv thiab tshem tawm thaum lub sij hawm tsim khoom thiab kev sim ntau lawm txheej txheem, tus naj npawb ntawm cov sij hawm loj heev, uas ua rau qhov kev sib cuag tau hloov pauv txawv txav. Amplify qhov txawv txav ntawm kev sib cuag impedance nyob rau hauv lub vibration xeev, ua rau lub teeb liab waveform variation (tom qab tshem tawm qhov kev co, lub waveform rov qab mus rau qhov qub). Tsuas yog yuav tsum tau hloov lub connector tshiab, lub waveform variation tshwm sim nyob rau hauv lub vibration xeev yuav ploj mus.
(A) RE xeem dhau tus qauv, koj tsuas yog yuav tsum tau polish lub installation ib feem ntawm aviation plug ntawm lub vaj huam sib luag nrog sandpaper los daws qhov teeb meem, los yog hloov lub gasket nyob rau hauv txoj cai daim duab hauv qab no los daws qhov teeb meem;
(B) Hom hom tam sim no hla tag nrho PCB pawg thawj coj saib thiab ua rau tag nrho PCB board. Tej zaum koj tsuas yog yuav tsum tau tso lub connector rau ntawm ib sab raws li qhia hauv daim duab hauv qab no los daws qhov teeb meem;
(C) Yog hais tias tus ncej ntawm tus ncej (saib daim duab hauv qab no) rau qhov txuas txuas ntev dhau lawm, cov nyhuv kav hlau txais xov yuav pom tseeb, thiab qhov teeb meem tuaj yeem daws tau los ntawm kev hloov cov teeb liab txheej;
(D) Cov kev txiav txim siab sib haum xeeb ntawm cov kab sib kis yog tuab heev thiab lub suab nrov heev. Txhawm rau txo cov suab nrov nrov ntawm lub zog, cov kab hluav taws xob sib txuas tuaj yeem tsuas yog ntsia rau ntawm qhov kawg ntawm qhov txuas raws li qhia hauv daim duab hauv qab no, thiab lwm yam.
Tag nrho cov qauv ntawm lub connector, ib feem ntawm cov qauv thiab cov khoom xaiv, kev sib cuag qhov chaw, cantilever, barbs, solder taw thiab cov khoom siv strips thiab electroplating, hom xaiv, installation txoj kev, thiab installation qhov chaw, thiab lwm yam, tag nrho cov ncaj qha cuam tshuam qhov kev ntseeg ntawm cov khoom. Muaj feem cuam tshuam rau qhov kev xeem ntawm cov khoom dhau los ntawm EMC daim ntawv pov thawj.
Ib qho kev sib txuas zoo tsim thiab kev siv zoo ntawm cov khoom sib txuas tuaj yeem txhim kho EMC kev ua tau zoo ntawm cov khoom.
Ntxiv rau qhov kev tshuaj xyuas ntawm cov khoom sib txuas' kev sib cuag khub xaiv, cov kws tshaj lij kev lag luam kuj tau ua cov kev sib tham ntxaws ntxaws ntawm cov ncauj lus hauv qab no:
(1) Ntawm lub tshuab thev naus laus zis twg, nyob rau hauv qhov ntau zaus, thiab ntawm pes tsawg degrees ntawm qhov kub thiab txias, hom connector yuav tsum xaiv? Dab tsi ntawm connector cantilever lossis koob puncture yog deformed?
(2) Puas yog nws tsim nyog los ntsuas qhov kev sib cuag impedance thiab cov yam ntxwv impedance nkaus xwb rau cov khoom siv hluav taws xob siab lossis cov khoom siv siab?
(3) Puas yog hom sib txawv thiab hom suab nrov yuav raug tsim tawm ntawm qhov txuas?
(4) Ntau npaum li cas dB poob ntawm qhov qub teeb liab tom qab lub connector txuas?
(5) Yuav ua li cas tshem tawm cov drift thiab jitter uas tshwm sim thaum lub teeb liab dhau los ntawm lub connector?
(6) Ntau npaum li cas dB ntawm kev tiv thaiv kev ua tau zoo tuaj yeem poob los ntawm kev teeb tsa ntawm qhov txuas?
(7) Lub zog hluav taws xob ntau npaum li cas tuaj yeem ua los yog hluav taws xob los ntawm qhov chaw nres nkoj?
(8) Yuav ua li cas tiv thaiv tam sim no ntawm tus pins connector tsis raug shunted?
(9) Dab tsi cuam tshuam rau EMC kev ua haujlwm ntawm cov khoom txuas?
(10) Yuav ua li cas ntsuas qhov EMC tsis txwv ntawm pawg thawj coj-theem connectors?
(11) Yuav siv cov connectors li cas los tiv thaiv SI thiab tiv thaiv ESD thiab Surge teeb meem tshwm sim?
(12) Yuav siv cov khoom sib txuas li cas los daws cov teeb meem EMI thiab kho EMC kev ua tau zoo ntawm cov khoom?
