Cov txheej txheem ntau lawm
Tom qab cov khoom xaiv, los ntawm cov txheej txheem ntau lawm los tswj cov zawv zawg phaj thiab sandwich phaj ua qhov tseem ceeb dua.Txhim kho tus naj npawb ntawm dabtsi yog khoov, nws yuav tsum tau tshwj xeeb tshaj yog tswj thaum ua hnyav hluav taws xob tooj liab txheej txheem.General nws yuav tsum tau ntawm lub neej rau zawv zawg phaj thiab a multilayer txheej phaj, lub xov tooj ntawm tes kev lag luam dav dav yam tsawg kawg nkaus khoov ncav cuag 80000 zaug.
Rau FPC siv cov txheej txheem dav dav rau tag nrho cov txheej txheem plating, tsis zoo li nyuaj tom qab daim duab tram, yog li hauv cov tooj liab plating tsis tas yuav tsum tau plated tooj liab tuab heev, nto tooj liab hauv 0.1 ~ 0.3 mil yog qhov tsim nyog tshaj plaws.(ntawm cov tooj liab plating. tooj liab thiab tooj liab deposition ratio yog hais txog 1: 1) tab sis nyob rau hauv thiaj li yuav xyuas kom meej qhov zoo ntawm lub qhov tooj liab thiab SMT qhov tooj liab thiab lub hauv paus cov ntaub ntawv ntawm kub kub stratification, thiab mounted rau cov hluav taws xob conductivity ntawm cov khoom thiab kev sib txuas lus, tooj liab tuab degree yuav tsum tau. yog 0.8 ~ 1.2 mil los yog siab dua.
Nyob rau hauv rooj plaub no tuaj yeem muaj teeb meem, tej zaum ib tus neeg yuav nug, qhov kev thov tooj liab tsuas yog 0.1 ~ 0.3 mil, thiab (tsis muaj tooj liab substrate) qhov xav tau tooj liab hauv 0.8 ~ 1.2 mil?Koj ua li cas? Qhov no yuav tsum tau ua kom cov txheej txheem dav dav ntawm FPC board (yog tias xav tau tsuas yog 0.4 ~ 0.9 mil) plating rau: txiav thiab drilling rau tooj liab plating (dub qhov), hluav taws xob tooj liab (0.4 ~ 0.9 mil) - graphics - tom qab txheej txheem.
Raws li kev lag luam hluav taws xob xav tau rau FPC cov khoom lag luam ntau dua thiab muaj zog, rau FPC, kev tiv thaiv cov khoom lag luam thiab kev ua haujlwm ntawm tus kheej kev nco qab ntawm cov khoom lag luam muaj txiaj ntsig tseem ceeb ntawm kev tshuaj xyuas zaum kawg los ntawm kev ua lag luam, kev tsim khoom tau zoo hauv cov txheej txheem tsim khoom thiab cov khoom yuav yog ib qho tseem ceeb ntawm qhov hnyav ntawm cov ntawv luam tawm Circuit Board kev sib tw.Thiab rau nws cov xim, kuj yuav yog ntau lub tuam txhab los xav txog thiab daws qhov teeb meem.
