Muaj ntau lub cim ntawm PCB pawg thawj coj saib, yog li dab tsi yog qhov tseem ceeb hauv lub sijhawm tom ntej? Cov cim: "R" sawv cev rau qhov tsis kam, "C" sawv cev rau cov capacitors, "RV" sawv cev rau kev hloov kho tau, "L" sawv cev rau inductance, "Q" sawv cev rau triode, "d" txhais tau tias Nws yog lub raj thib ob. "X lossis Y" txhais tau hais tias siv lead ua vibration, "U" txhais tau tias yog ib qho kev sib txuas ua ke, thiab lwm yam.
Feem ntau, lwm cov cim tshwj tsis yog tus lej me me sawv cev rau qee cov qauv, cov ncej zoo thiab tsis zoo, cov qauv qauv, thiab cov thawv teeb yog lub thawv cim. Nyob rau hauv tus txheej txheem ntawm kev tsim thiab kev tsim khoom, koj yuav tsum xav txog qhov ntse ntawm tus cwj pwm. Cov cim tsim tshwj xeeb thiab cov khoom siv lub logo yog qhov tseeb, yog li kev tsim khoom tuaj yeem tsim cov cim meej. Muaj cov cim meej ntawm lub rooj tsavxwm kom tsis txhob muaj qhov yuam kev thaum lub sij hawm vuam thiab kev kho tom qab.
Tus cwj pwm tsim tus kheej ntawm PCB pawg thawj coj saib
01. Silk print naj npawb
Kev siv cov zauv luam ntawv yog rau cov khoom siv tom qab sib dhos, tshwj xeeb tshaj yog cov khoom siv sib dhos. Feem ntau, daim duab sib dhos ntawm PCB yog siv rau cov khoom siv hauv qhov chaw. tseem ceeb.
02. Cov cim Polaris
Nyob rau hauv keeb kwm ntawm hluav taws xob, lub ntsiab lus ntawm polarity yog cov kev taw qhia ntawm tam sim no ntws hauv Circuit Court. PCB encapsulated cim polar tsim yog them sai sai rau qhov zoo thiab tsis zoo electrodes.
03. Ib ko taw logo
Integrated Circuit packaging feem ntau muaj ntau tus pins, thiab ib-footed logo yog cov kev taw qhia ntawm qhov txawv ntawm cov khoom siv. Yog hais tias lub PCB ntim cov ntawv lo lo lo ntxhuav luam ntawv cim tsis muaj ko taw logo, los yog txoj hauj lwm ntawm ib ko taw logo tsis ncaj ncees lawm, nws yuav ua rau cov khoom siv los tiv thaiv cov khoom tsis ua haujlwm.
Tus cwj pwm tsim teeb meem ntawm PCB board
01. Tus lej me me raug them
Cov cim hauv kev txheeb xyuas cov khoom siv tau tuaj yeem muaj uas cov cim raug thaiv lossis npog los ntawm cov khoom siv. Nws yuav ua rau muaj teeb meem hauv kev sib dhos vuam, thiab nws tseem yuav ua rau tsis yooj yim rau kev kho tom ntej.
02. Tus lej txoj haujlwm nyob deb dhau ntawm lub ncoo
Cov cim tus lej me ntsis nyob deb dhau ntawm cov khoom tivthaiv, uas yuav ua rau tus lej sib raug zoo thaum lub thaj ua ke, thiab tej zaum yuav muaj kev pheej hmoo ntawm kev sib tsoo cov nplaum yuam kev.
03. Pitzer lo lus sib tshooj
Kev sib cuag lossis sib tshooj ntawm cov ntawv luam ntawv sib txawv yuav ua rau cov ntaub ntawv luam tawm tsis pom tseeb. Thaum sib dhos cov khoom, nws tsis tuaj yeem paub qhov txawv ntawm lub rooj ntim khoom sib haum rau cov khoom. Yuav muaj kev pheej hmoo ntawm welding stickers.
