Product Detail

Hais txog Via-In-Pad PCB

Cov Via-In-Pad PCBs feem ntau yog qhov muag tsis pom qhov, uas yog siv los txuas cov txheej sab hauv lossis cov txheej txheem thib ob ntawm HDI PCB nrog cov txheej txheej sab nrauv, txhawm rau txhim kho cov khoom siv hluav taws xob thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob, ua kom luv luv. xaim xaim, txo qhov inductive reactance thiab capacitive reactance ntawm cov kab sib kis, nrog rau kev cuam tshuam sab hauv thiab sab nraud electromagnetic.

Nws yog siv rau kev ua.Qhov teeb meem tseem ceeb ntawm lub qhov ntsaws hauv PCB kev lag luam yog cov roj to ntawm lub qhov ntsaws, uas tuaj yeem hais tias yog ib qho kab mob tsis tu ncua hauv kev lag luam.Nws cuam tshuam rau kev tsim khoom zoo, lub sijhawm xa khoom thiab kev ua haujlwm ntawm PCB.Tam sim no, feem ntau high-end ntom PCBs muaj cov qauv zoo li no.Yog li ntawd, PCB kev lag luam urgently yuav tsum tau daws qhov teeb meem ntawm cov roj to los ntawm plug qhov

Lub ntsiab yam tseem ceeb ntawm cov roj emission ntawm Via nyob rau hauv Pad Plug Qhov

Qhov sib nrug ntawm lub qhov ntsaws thiab lub ncoo: nyob rau hauv qhov tseeb PCB los tiv thaiv vuam txheej txheem, tshwj tsis yog lub phaj qhov yog yooj yim rau kev khiav.Lwm qhov ntsaws qhov thiab qhov rais qhov sib nrug yog tsawg dua 0.1mm 4mil) thiab ntsaws qhov thiab tiv thaiv lub qhov rais tangential, kev sib tshuam phaj kuj yog ib qho yooj yim kom muaj nyob tom qab kho cov roj to;

PCB thickness thiab aperture: phaj thickness thiab aperture yog zoo correlated nrog cov degree thiab feem ntawm cov roj emission;

Parallelic zaj duab xis tsim: thaum Via-In-Pad PCB lossis qhov sib nrug me me cuam tshuam lub ncoo, zaj duab xis parallelic feem ntau yuav tsim lub teeb xa hluav taws xob ntawm lub qhov rais txoj haujlwm (kom nthuav tawm tus cwj mem hauv lub qhov) "kom tsis txhob muaj tus cwj mem hauv lub qhov nkag mus rau hauv lub ncoo thaum lub sij hawm txoj kev loj hlob, tab sis lub teeb transmittance tsim yog me me heev kom ua tiav cov nyhuv ntawm raug, thiab lub teeb transmittance point yog loj heev kom yooj yim ua rau offset.Tsim cov roj ntsuab ntawm PAD.

Curing tej yam kev mob: vim hais tias tus tsim ntawm translucent point ntawm Via-In-Pad PCB rau cov zaj duab xis yuav tsum me dua lub qhov, ib feem ntawm tus number case nyob rau hauv lub qhov yog ntau dua lub translucent point thaum raug tsis raug rau lub teeb.Ink tsis yog photosensitive curing, kev loj hlob tom qab qhov kev xav tau rov qab los yog UV ib zaug, txhawm rau kho tus number case ntawm no.Ib txheej ntawm curing zaj duab xis yog tsim nyob rau saum npoo ntawm lub qhov los tiv thaiv thermal expansion ntawm number case nyob rau hauv lub qhov tom qab kho.Tom qab kho, lub sij hawm ntev ntawm qhov qis qis, thiab qhov kub ntawm qhov qis qis, qhov kev faib ua feem me me thiab qib ntawm cov roj emission;

Plugging number case: txawv manufacturers ntawm tus number case formula txawv cov nyhuv zoo kuj yuav muaj qhov sib txawv.
