Hluav taws xob kev nyab xeeb nrug
1. Qhov sib nrug ntawm cov xov hlau
Raws li lub peev xwm ntau lawm ntawm PCB cov tuam txhab, qhov kev ncua deb ntawm cov kab thiab kab yuav tsum tsis pub tsawg dua 4 mil. Qhov tsawg kawg ntawm kab sib nrug kuj yog kab-rau-kab thiab kab-rau-pad sib nrug. Zoo, los ntawm peb qhov kev xav ntau lawm, tau kawg, qhov loj dua qhov zoo dua nyob rau hauv cov xwm txheej. Feem ntau 10 mil yog ntau dua.
2. Pad aperture thiab ncoo dav:
Raws li cov chaw tsim tshuaj paus PCB, qhov tsawg kawg nkaus txoj kab uas hla ntawm lub ncoo yog tsis tsawg tshaj li 0.2 hli yog hais tias nws yog mechanically drilled, thiab nws tsis tsawg tshaj li 4 mil yog hais tias nws yog laser drilled. Lub aperture kam rau ua yog txawv me ntsis nyob ntawm lub phaj. Feem ntau nws tuaj yeem tswj tau hauv 0.05 hli. Qhov tsawg kawg nkaus qhov dav ntawm lub ncoo yuav tsum tsis pub tsawg tshaj 0.2 hli.
3. Qhov kev ncua deb ntawm lub ncoo thiab lub ncoo:
Raws li kev ua tau zoo ntawm PCB cov tuam txhab, qhov kev ncua deb ntawm cov ntaub qhwv thiab cov ntaub qhwv yuav tsum tsis pub tsawg dua 0.2 hli.
4. Qhov kev ncua deb ntawm daim tawv nqaij tooj liab thiab ntug ntawm lub rooj tsavxwm:
Qhov kev ncua deb ntawm daim tawv nqaij tooj liab thiab ntug ntawm PCB pawg thawj coj saib zoo dua tsis pub tsawg dua 0.3 hli. Yog tias tooj liab muab tso rau ntawm thaj chaw loj, feem ntau nws yog qhov tsim nyog yuav tsum muaj qhov kev ncua deb ntawm ntug ntawm lub rooj tsavxwm, uas feem ntau yog teem rau 20 mil. Feem ntau, vim yog kev xav txog kev xav ntawm lub rooj tsavxwm ua tiav, lossis kom tsis txhob muaj qhov ua tau ntawm curling lossis hluav taws xob luv luv los ntawm kev nthuav tawm tooj liab rau ntawm ntug ntawm lub rooj tsavxwm, cov kws ua haujlwm feem ntau ua rau qhov loj ntawm cov tooj liab blocks los ntawm 20 mil txheeb ze. ntug ntawm lub rooj tsavxwm. Cov tawv nqaij tooj liab tsis tas yuav kis mus rau ntawm ntug ntawm lub rooj tsavxwm. Muaj ntau txoj hauv kev los daws qhov no tooj liab shrinkage. Piv txwv li, kos cov txheej txheem khaws cia rau ntawm ntug ntawm lub rooj tsavxwm, thiab tom qab ntawd muab qhov kev ncua deb ntawm cov tooj liab thiab khaws cia.
Tsis yog hluav taws xob kev nyab xeeb nyob deb
1. Tus cwj pwm dav thiab qhov siab thiab qhov sib txawv:
Hais txog cov cim ntawm silk screen, peb feem ntau siv cov txiaj ntsig zoo xws li 5/30 6/36 MIL, thiab lwm yam. Vim tias thaum cov ntawv nyeem me dhau, kev ua haujlwm thiab luam ntawv yuav plooj.
2. Qhov kev ncua deb ntawm silk screen rau ncoo:
Screen luam ntawv tsis pub cov ntaub qhwv. Yog hais tias lub xov tooj ntawm tes yog npog nrog cov ntaub qhwv, lub tin yuav tsis tinned thaum soldering, uas yuav cuam tshuam rau qhov chaw ntawm cov khoom. General board manufacturers xav tau 8 mil qhov sib txawv kom tau tshwj tseg. Yog tias nws yog vim thaj tsam ntawm qee qhov PCB boards ze heev, qhov sib nrug ntawm 4MIL yog qhov tsis txaus ntseeg. Tom qab ntawd, yog tias lub vijtsam txhob lo lo ntxhuav npog lub ncoo thaum lub sijhawm tsim, lub rooj tsavxwm cov chaw tsim khoom yuav cia li tshem tawm cov ntawv lo lo ntxhuav sab laug ntawm lub ncoo thaum tsim khoom los xyuas kom meej cov tin ntawm lub ncoo. Yog li peb yuav tsum tau ua tib zoo mloog.
3. 3D qhov siab thiab kab rov tav qhov sib txawv ntawm cov qauv siv tshuab:
Thaum txhim kho cov cuab yeej ntawm PCB, nws yuav tsum tau txiav txim siab seb qhov kev taw qhia kab rov tav thiab qhov chaw siab yuav cuam tshuam nrog lwm cov qauv siv tshuab. Yog li ntawd, thaum tsim, nws yog tsim nyog los xav txog tag nrho cov adaptability ntawm lub spatial qauv ntawm lub Cheebtsam, raws li zoo raws li nruab nrab ntawm cov khoom PCB thiab cov khoom plhaub, thiab cia ib tug nyab xeeb nyob deb ntawm txhua lub hom phiaj.
