Ib Nrab Qhov PCB Sensor Ib Nrab Qhov PCB
Plated Ib Nrab Qhov
Ib lub qhov ib nrab plated, tseem hu ua lub qhov castellated, yog ib lub qauv tsim raws ntug ntawm PCB zoo li cov npoo serrated. Nws yog tsim los ntawm kev tsim cov vias plated txheem thiab tom qab ntawd siv lub cuab yeej milling ntse los txiav ib feem ntawm lub qhov, tawm ib nrab ntawm nws tseem zoo.
Tus qauv tsim no yog ib txoj kev siv tau zoo thiab yooj yim rau kev sib txuas sab nraud, feem ntau siv rau hauv cov voj voog teeb liab thiab dav dav rau kev sib txuas ntawm lub rooj tsavxwm. Cov qhov ib nrab plated tuaj yeem txuas ncaj qha rau ntawm ntug ntawm lub rooj tsavxwm tseem ceeb, txuag cov khoom sib txuas thiab qhov chaw. Piv txwv li, Bluetooth lossis Wi-Fi modules nrog cov qhov ib nrab plated tuaj yeem txuas tau yooj yim rau ntawm lub rooj tsavxwm tseem ceeb ua ib qho khoom, ua tau raws li cov kev xav tau tshwj xeeb yam tsis tas yuav tsum tau ntxiv cov xov hlau, ua rau muaj kev sib dhos huv si thiab yooj yim.
Txawm hais tias cov qhov ib nrab uas tau plated ua rau kev sib txuas ntawm cov laug cam yooj yim dua, lawv suav hais tias yog cov thev naus laus zis tshwj xeeb hauv kev lag luam PCB thiab muaj tus nqi siab dua. Tsis tas li ntawd, lub voj voog tsim khoom rau cov PCBs no ntev dua.
Cov yam ntxwv ntawm Sensor Ib Nrab Qhov PCBs
1. Tsim Qauv Me Me:
Cov PCB ib nrab qhov rau cov sensors yog tsim los kom me me, uas ua rau siv tau qhov chaw zoo hauv cov sensor modules me me. Qhov me me no yog qhov tseem ceeb rau kev sib txuas cov sensors rau hauv qhov chaw nqaim hauv cov khoom siv.

Tus qauv tsim no txo qhov xav tau cov khoom txuas ntxiv thiab pab ua kom cov txheej txheem sib dhos yooj yim dua.
3. Kev Txhim Kho Lub Teeb Liab Zoo Dua:
Cov qhov ib nrab pab tswj kev ncaj ncees ntawm cov teeb liab los ntawm kev txo qhov deb ntawm cov kev teeb liab thiab txo qhov cuam tshuam. Qhov no tseem ceeb heev rau cov sensors uas vam khom kev xa cov ntaub ntawv raug rau kev ua tau zoo.
4. Kev Tsim Khoom Uas Pheej Yig:
Los ntawm kev siv cov qhov ib nrab, cov chaw tsim khoom feem ntau tuaj yeem txo cov nqi cuam tshuam nrog cov khoom sib txuas thiab kev sib dhos. Qhov no yog vim muaj peev xwm vuam ncaj qha ntawm cov qhov ib nrab, uas ua rau cov txheej txheem tsim khoom yooj yim dua.
5. Kev Txhim Kho Qhov Chaw:
Kev siv cov qhov ib nrab ua rau muaj kev tswj qhov chaw zoo dua ntawm PCB. Qhov no muaj txiaj ntsig zoo rau cov ntawv thov sensor uas qhov chaw tsawg thiab kev teeb tsa zoo yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua tau zoo.
6. Cov Ntawv Thov Ntau Yam:
Cov PCBs ib nrab qhov ntawm lub sensor muaj ntau yam siv tau thiab siv tau rau ntau hom sensors, suav nrog cov sensors ib puag ncig, cov sensors txav mus los, thiab cov sensors duab. Lawv tus qauv tsim ua raws li qhov loj me ntawm lub sensor thiab qhov yuav tsum tau teeb tsa sib txawv.
7. Kev Txhim Kho Kev Ntseeg Siab:
Cov PCBs ib nrab qhov ua rau cov sensors muaj kev ntseeg siab dua los ntawm kev muab txoj kev sib txuas ruaj khov. Qhov no txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm cov khoom siv thiab ua kom cov khoom sib dhos sensor ruaj khov dua.
Kev Tsim Khoom Siv Tau ntawm Ib Nrab Qhov PCBs
Qhov Loj Tsawg Kawg Nkaus Ib Nrab Qhov
Qhov tsawg kawg nkaus uas tsim tau rau ib nrab qhov yog 0.5 hli, yog tias lub qhov nyob hauv nruab nrab ntawm ntug ntawm PCB. Qhov no txhais tau tias yuav tsum muaj thaj tsam tooj liab 0.25 hli hauv PCB kom ntseeg tau tias lub qhov yog qhov tseeb. Yog tsis muaj thaj tsam tooj liab nruab nrab no, tooj liab ntawm phab ntsa qhov yuav tawg thaum lub sijhawm tsim khoom, ua rau muaj cov qhov tsis tau plated thiab ua rau cov khoom kawg siv tsis tau.
Qhov Sib Nrug Ib Nrab Qhov
Rau cov PCBs ib nrab qhov, qhov tsawg kawg nkaus ntawm qhov tiav lawm yog 0.5 hli. Thaum lub sijhawm tsim khoom, qhov loj ntawm qhov yuav tsum tau them rov qab. Tom qab them rov qab, qhov sib nrug ntawm ib nrab qhov yuav tsum yog tsawg kawg 0.35 hli. Yog li ntawd, qhov sib nrug tsim ntawm ib nrab qhov yuav tsum yog ≥0.45 hli. Cov ntaub nplaum sib xws rau ib nrab qhov yuav tsum tau them rov qab kom ntseeg tau tias lawv yog ≥0.25 hli. Tsis tas li ntawd, yuav tsum muaj tus choj solder mask ntawm qhov qhib solder mask thiab cov ntaub nplaum solder rau ib nrab qhov.
Kev Sib Txuas Ib Nrab Qhov
Thaum ua vaj huam sib luag rau cov PCBs ib nrab qhov, nws yog ib qho tseem ceeb uas yuav tsum tso qhov sib nrug ib puag ncig cov qhov ib nrab kom yooj yim rau kev teeb tsa thiab kev txiav. Cov ntsiab lus no feem ntau tsis quav ntsej thaum lub sijhawm tsim qauv vim tias muaj ob peb tus kws tsim qauv tau mus xyuas cov chaw tsim khoom PCB kom nkag siab txog kev tsim cov qhov ib nrab. Yog li ntawd, cov khoom ib nrab qhov qee zaum raug ua vaj huam sib luag yam tsis muaj qhov sib nrug zoo, siv cov txheej txheem V-CUT tus qauv. Qhov no tuaj yeem ua rau tooj liab ntawm cov qhov ib nrab raug rub tawm los ntawm cov hniav V-CUT, ua rau cov qhov tsis tau plated thiab ua rau cov khoom siv tsis tau.

Ib Nrab Qhov PCB
Cov PCBs ib nrab qhov muaj cov kab ntawm cov qhov uas tau tho raws ntug ntawm PCB. Thaum cov qhov no yog tooj liab-plated, cov npoo raug txiav, ua rau pom ib nrab-plated raws ciam teb. Tus qauv no ua rau ntug PCB zoo li tooj liab-plated.
Hauv cov PCBs hom module, ib nrab qhov feem ntau yog sib xyaw ua ke los pab txhawb kev vuam. Vim yog qhov me me thiab ntau yam kev xav tau ntawm cov modules, ib nrab qhov feem ntau yog muab tso rau ntawm ntug ntawm PCB. Thaum lub sijhawm ua haujlwm, ib nrab ntawm ntug raug txiav tawm, tsuas yog tso cov qhov ib nrab-plated pom ntawm PCB.
Txoj kev tsim qauv no ua rau kom yooj yim ntawm kev vuam thiab ua raws li qhov xav tau ntawm cov modules compact, multifunctional.
Cov Teeb Meem ntawm Kev Tsim Khoom PCB Ib Nrab Qhov
Hauv kev ua ib nrab qhov, yog tias cov tooj liab burrs tseem nyob hauv cov qhov hlau, nws tuaj yeem ua rau muaj teeb meem xws li cov pob qij txha tsis muaj zog, kev soldering txias, thiab luv luv ntawm cov pins, tshwj xeeb tshaj yog nyob rau hauv kab ntawm ib nrab qhov uas qhov sib nrug me me heev thiab yooj yim luv luv circuits. Thaum lub sijhawm txheej txheem routing, teeb meem xws li tooj liab nce ntawm phab ntsa qhov thiab cov burrs seem yog qhov tshwm sim, feem ntau yog vim tsis txaus routing cuab yeej ceev, tsis txaus sib txuas ntawm tooj liab thiab phab ntsa qhov, thiab tooj liab tuab ntau dhau uas ua rau txiav tsis tiav.
Tsis tas li ntawd xwb, yog tias muaj cov qhov ib nrab uas ua los ntawm hlau, qhov sib txawv ntawm kev nthuav dav ntawm PCB, kev ntsuas qhov tseeb, thiab kev tsim qhov tseeb tuaj yeem ua rau muaj qhov sib txawv loj ntawm cov qhov ib nrab ntawm ob sab ntawm tib lub tshuab. Qhov sib txawv no ua rau muaj teeb meem loj rau cov neeg siv khoom thaum lub sijhawm vuam thiab sib dhos.
Vim Li Cas Cov Nqi Ntxiv ntawm Ib Nrab Qhov PCBs
Ib nrab qhov muaj cov txheej txheem tsim khoom tshwj xeeb. Yuav kom ntseeg tau tias muaj tooj liab nyob hauv cov qhov, cov npoo yuav tsum tau xa mus rau ib nrab ntawm cov txheej txheem. Tsis tas li ntawd, cov PCBs ib nrab qhov feem ntau me me heev, uas ua rau tus nqi nce ntxiv. Yog li ntawd, cov qauv tsim tsis yog tus qauv tuaj nrog tus nqi tsis yog tus qauv.
