PCB silk screenluam ntawv yog txheej txheem tseem ceeb hauv kev tsim cov PCB Circuit Board, uas txiav txim siab qhov zoo ntawm cov khoom tiav PCB. PCB Circuit Board tsim yog qhov nyuaj heev. Muaj ntau cov ntsiab lus me me hauv cov txheej txheem tsim. Yog tias nws tsis ua haujlwm zoo, nws yuav cuam tshuam rau kev ua haujlwm ntawm tag nrho PCB pawg thawj coj saib. Txhawm rau ua kom muaj txiaj ntsig zoo tshaj plaws thiab cov khoom lag luam zoo, cov teeb meem dab tsi peb yuav tsum tau them rau thaum tsim?
Cov cim duab yog tsim rau ntawm pcb board los ntawm silk screen lossis inkjet luam ntawv. Txhua tus cwj pwm sawv cev rau qhov sib txawv thiab ua lub luag haujlwm tseem ceeb hauv kev tsim tom qab.
Cia kuv qhia txog cov cim. Feem ntau, C stands rau capacitor, R stands rau resistor, L stands rau inductor, Q stands rau transistor, D stands rau diode, Y stands rau siv lead ua oscillator, U stands rau integrated circuit, B stands rau buzzer, T stands rau transformer, K sawv cev rau Relays thiab ntau dua.
Nyob rau ntawm lub rooj tsavxwm Circuit Court, peb feem ntau pom cov lej xws li R101, C203, thiab lwm yam. Qhov tseeb, thawj tsab ntawv sawv cev rau pawg tivthaiv, tus lej thib ob qhia txog tus lej ua haujlwm hauv Circuit Court, thiab tus lej thib peb thiab tus lej thib plaub sawv cev rau tus lej ntawm lub voj voog. lub rooj tsavxwm. Yog li peb nkag siab zoo heev tias R101 yog thawj resistor ntawm thawj lub luag haujlwm Circuit Court, thiab C203 yog tus thib peb capacitor ntawm qhov thib ob ua haujlwm Circuit Court, kom tus cwj pwm qhia tau yooj yim to taub.
Qhov tseeb, cov cim ntawm PCB Circuit Board yog qhov peb feem ntau hu ua silk screen. Thawj qhov uas cov neeg siv khoom pom thaum lawv tau txais PCB pawg thawj coj saib yog lub vijtsam silk ntawm nws. Los ntawm cov cim silk screen, lawv tuaj yeem nkag siab meej tias cov khoom yuav tsum tau muab tso rau hauv txhua txoj haujlwm thaum lub sijhawm teeb tsa. Yooj yim rau kev sib sau ua ke thiab kho. Yog li cov teeb meem dab tsi yuav tsum tau them nyiaj rau hauv cov txheej txheem tsim ntawm silk screen printing?
1) Qhov kev ncua deb ntawm silk screen thiab lub ncoo: lub silk screen tsis tuaj yeem muab tso rau ntawm lub ncoo. Yog hais tias lub ncoo yog npog los ntawm silk screen, nws yuav cuam tshuam rau soldering ntawm lub Cheebtsam, yog li ib tug 6-8mil spacing yuav tsum tau tshwj tseg.2) Screen printing dav: lub screen printing kab dav yog feem ntau ntau tshaj 0.1mm (4 zeb), uas yog hais txog qhov dav ntawm tus cwj mem. Yog tias cov kab dav me dhau lawm, tus cwj mem yuav tsis tawm ntawm lub vijtsam luam ntawv, thiab cov cim tsis tuaj yeem luam tawm.3) Cov cim qhov siab ntawm silk screen luam ntawv: Cov cim qhov siab feem ntau yog siab tshaj 0.6mm (25mil). Yog tias tus cwj pwm qhov siab tsawg dua 25mil, cov ntawv luam tawm yuav tsis meej thiab yooj yim plooj. Yog hais tias tus cwj pwm kab yog tuab dhau los yog qhov deb dhau los ze, nws yuav ua rau plooj.
4) Kev taw qhia ntawm silk screen luam ntawv: feem ntau ua raws li txoj cai ntawm sab laug mus rau sab xis thiab hauv qab mus rau sab saum toj.
5) Polarity txhais: Cov khoom feem ntau muaj polarity. Cov qauv luam ntawv luam ntawv yuav tsum tau them sai sai rau qhov cim qhov zoo thiab qhov tsis zoo ntawm cov ncej thiab cov lus taw qhia. Yog tias qhov zoo thiab qhov tsis zoo ntawm cov ncej yog thim rov qab, nws yog ib qho yooj yim uas yuav ua rau luv luv Circuit Court, ua rau lub rooj tsav xwm hluav taws xob hlawv thiab tsis tuaj yeem npog.
6) Pin ID: Tus pin ID tuaj yeem paub qhov txawv ntawm cov khoom. Yog tias cov cim silk screen cim qhov kev qhia tsis raug lossis tsis muaj kev txheeb xyuas, nws yooj yim ua rau cov khoom sib txuas rov qab.
7) Silk screen txoj hauj lwm: Tsis txhob tso cov silk screen tsim rau ntawm lub qhov drilled, txwv tsis pub lub pcb board luam ntawv yuav muaj cov cim tsis tiav.
Muaj ntau yam specifications thiab yuav tsum tau rau PCB silk screen tsim, thiab nws yog cov specifications uas txhawb kev loj hlob ntawm PCB screen printing tshuab.
