Daim ntawv thov
PCB ib nrab lub qhov rooj yog hais txog qhov thib ob qhov drilling thiab cov txheej txheem tom qab thawj lub qhov yog drilled, thiab thaum kawg ib nrab ntawm lub qhov metallized yog tseg.Lub hom phiaj yog txhawm rau txuas ncaj qha rau ntawm ntug ntawm lub qhov mus rau lub ntsiab ntug kom txuag cov connectors thiab qhov chaw, thiab feem ntau tshwm sim hauv cov teeb liab circuits.
Ib nrab lub qhov hluav taws xob Circuit Court boards feem ntau yog siv rau mounting high-density electronics Cheebtsam, xws li mobile devices, smart watches, cov khoom siv kho mob, suab thiab video khoom, thiab lwm yam. Lawv pab kom siab dua circuit density thiab ntau connectivity xaiv, ua electronics me me, sib dua. thiab ua tau zoo dua.
Qhov tsis yog-plated ib nrab qhov ntawm cov npoo ntawm PCB yog ib qho ntawm cov qauv siv feem ntau hauv cov txheej txheem tsim khoom PCB, thiab nws lub luag haujlwm tseem ceeb yog kho PCB.Nyob rau hauv cov txheej txheem ntawm PCB pawg thawj coj saib ntau lawm, los ntawm kev tawm ib nrab qhov ntawm qee txoj haujlwm ntawm ntug ntawm PCB pawg thawj coj saib, PCB board tuaj yeem kho ntawm lub cuab yeej lossis lub vaj tsev nrog screws.Nyob rau tib lub sijhawm, thaum lub sijhawm PCB pawg thawj coj ua ke, ib nrab lub qhov tseem yuav pab tau txoj haujlwm thiab ua kom lub PCB pawg thawj coj saib xyuas qhov tseeb thiab ruaj khov ntawm cov khoom kawg.
Ib nrab qhov plated nyob rau sab ntawm lub rooj tsav xwm Circuit Court yog los txhim kho kev sib txuas kev ntseeg siab ntawm sab ntawm lub rooj tsavxwm.Feem ntau, tom qab cov ntawv luam tawm Circuit Board (PCB) raug txiav, cov txheej txheej tooj liab ntawm ntug yuav raug nthuav tawm, uas yog oxidation thiab corrosion.Txhawm rau daws qhov teeb meem no, cov txheej tooj tooj feem ntau yog coated rau hauv cov txheej txheem tiv thaiv los ntawm electroplating ntug ntawm lub rooj tsavxwm rau hauv ib nrab lub qhov los txhim kho nws cov oxidation tsis kam thiab corrosion kuj, thiab nws kuj tuaj yeem ua rau thaj tsam vuam thiab txhim kho kev ntseeg tau ntawm kev sib txuas.
Nyob rau hauv cov txheej txheem ntawm kev ua, yuav ua li cas tswj cov khoom zoo tom qab tsim semi-metallized qhov ntawm ntug ntawm lub rooj tsavxwm, xws li tooj liab pos rau ntawm lub qhov phab ntsa, thiab lwm yam., yeej ib txwm yog ib qho teeb meem nyuaj nyob rau hauv cov txheej txheem ua.Rau lub hom phiaj no nrog ib tug tag nrho kab ntawm semi-metallized qhov Lub PCB board yog yus muaj los ntawm ib tug kuj me me lub cheeb, thiab feem ntau yog siv rau cov ntxhais board ntawm lub motherboard.Los ntawm cov qhov no, nws yog welded ua ke nrog lub motherboard thiab cov pins ntawm cov khoom.Thaum soldering, nws yuav ua rau tsis muaj zog soldering, cuav soldering, thiab loj bridging luv luv Circuit Court ntawm ob tus pins.
FAQs
Tej zaum nws yuav muaj txiaj ntsig zoo rau qhov chaw plated qhov (PTH) ntawm lub rooj tsavxwm.Piv txwv li thaum koj xav solder ob lub PCB rau ib leeg nyob rau hauv ib tug 90 ° lub kaum sab xis los yog thaum soldering lub PCB rau ib tug hlau casing.
Piv txwv li, kev sib xyaw ua ke ntawm cov khoom siv microcontroler complex nrog ntau, tsim ib tus kheej PCBs.Cov ntawv thov ntxiv yog cov zaub, HF lossis ceramic modules uas yog soldered rau lub hauv paus luam ntawv Circuit Court board.
Drilling-plated los ntawm lub qhov (PTH) - vaj huam sib luag plating - duab hloov pauv - qauv plating -pth ib nrab lub qhov - striping - etching - solder mask - silkscreen - kho deg.
1.Diameter ≥0.6MM;
2.Qhov kev ncua deb ntawm lub qhov ntug ≥0.6MM;
3. Qhov dav ntawm etching nplhaib xav tau 0.25mm;
Ib nrab-qhov yog txheej txheem tshwj xeeb.Txhawm rau kom ntseeg tau tias muaj tooj liab hauv lub qhov, nws yuav tsum tau zeb ntug ua ntej ua ntej txheej txheej tooj liab.Qhov feem ntau ib nrab-qhov PCB yog me me, yog li tus nqi ntawm nws yog kim dua li cov PCB.
