HDI: Kev kub siab tshaj plaws ntawm cov tsiaj ntawv luv, cov kab tsis sib xws nrog cov kab hluav taws xob tsis ntau tshaj li 0.35mm multiilayer Board Protection yog hu ua HDI Board.
Qhov muag dig muag ntawm: luv luv rau dig muag ntawm, pom tau qhov kev sib txuas nrog nruab nrab ntawm cov khaubncaws sab nraud.
Faus los ntawm: luv luv rau faus ntawm, paub txog kev sib txuas ntawm txheej sab hauv thiab cov txheej sab hauv.
Blind via is mostly a small hole with a diameter of 0.05mm~0.15mm, buried via is formed by laser, plasma etching and photoluminescence, and is usually formed by laser, which is divided into CO2 and YAG ultraviolet laser (UV).
HDI board khoom siv
1.hdi phaj ntaub ntawv rcc, ldpe, FR4
RCC: Tsis ntev rau Resin Coated Coated Coated Caws Tooj Liab, Ras-resistant, thiab lwm yam yog muaj nyob hauv daim duab hauv qab no: (siv thaum lub tuab yog ntau tshaj 4mil)
Lub resin txheej ntawm RCC muaj tib lub thoob raws li Fr-1/4 daim ntawv cog lus sib khi (prepreg). Ntxiv rau kev ua tau raws li cov kev xav tau ntawm cov kev xav tau ntawm cov qauv siv ntau ntawm cov qauv kev sib txuam, xws li:
(1) Kev Rwb Cev Qhuab Qhia Siab Kev Cia Siab thiab Micro-kev ua qhov kev ntseeg tau;
(2) Cov ntsuas kub siab hloov (TG);
(3) Qes dielectric tas li thiab qis nqus dej;
(4) Cov khoom zoo nkauj siab thiab lub zog rau tooj liab ntawv ci;
(5) thooj tuab ntawm tuab ntawm rwb thaiv tsev txheej tom qab kho.
Tib lub sijhawm, vim tias RCC yog hom khoom lag luam tshiab uas tsis muaj cov iav fiber ntau, nws yog qhov zoo rau kev siv lub teeb thiab thearing ntawm multilayer board. Ib qho ntxiv, lub resin coated tooj liab ntawv muaj cov ntawv ci xws li 12pm, 18pm, thiab lwm yam, uas yooj yim rau cov txheej txheem.
Peb, thawj qhov kev txiav txim, tus lej thib ob pcb?
Thawj-xaj, thib ob hais txog tus naj npawb ntawm Laser qhov, PCB cov tub ntxhais tub ntxhais lub sijhawm ob peb zaug, ua si ntau zaug laser qhov! Yog ob peb xaj. Raws li qhia hauv qab no
1 ,. Nias ib zaug tom qab drilling qhov == "sab nraud ntawm xovxwm ib zaug kub tooj liab ntawv cop ==" thiab tom qab ntawd laser tho qhov
Nov yog thawj theem, raws li qhia hauv daim duab hauv qab no
2, tom qab nias ib zaug thiab laum qhov == "sab nraud ntawm lwm lub tooj liab
Qhov no yog qhov kev txiav txim thib ob. Nws feem ntau tsuas yog muaj feem ntau ntawm pes tsawg zaus koj laser nws, uas yog pes tsawg kauj ruam.
Thib ob tau muab faib ua cov qhov stacked thiab cais qhov.
Daim duab hauv qab no yog yim txheej ntawm thib ob txheej txheej pob, yog 3-6s thawj nias haum, sab nraum ntawm 2, 7 txheej tau nias, thiab ntaus lub laser lub sijhawm ib zaug. Tom qab ntawd tus 1,8 txheej tau nias thiab xuas nrig ntaus nrog laser qhov ib zaug ntxiv. Qhov no yog ua kom ob lub qhov laser. Qhov no zoo vim tias nws tau nyiag, cov txheej txheem nyuaj yuav yog qhov siab me ntsis, tus nqi yog qhov nqi me dua.
Daim duab hauv qab no qhia yim txheej ntawm thib ob-txiav txim hla lub qhov muag tsis pom kev, cov txheej txheem no yog tib yam nkaus li ntawm yim thib ob, kuj yuav tsum ntaus lub laser ob zaug. Tab sis lub qhov laser no tsis tau teev ua ke, kev ua nyuaj ua tiav yog tsawg dua.
Thib peb txiav txim, thib plaub kev txiav txim thiab lwm yam.
