Yog tias koj raug nug seb lub rooj tsav xwm hluav taws xob yog xim dab tsi, kuv ntseeg tias txhua tus thawj cov tshuaj tiv thaiv yog ntsuab. Kev lees paub, feem ntau ntawm cov khoom tiav hauv kev lag luam PCB yog ntsuab. Tab sis nrog txoj kev loj hlob ntawm kev siv tshuab thiab cov kev xav tau ntawm cov neeg siv khoom, ntau yam xim tau tshwm sim. Rov qab mus rau qhov chaw, vim li cas cov laug cam feem ntau ntsuab? Cia peb tham txog hnub no!
Qhov ntsuab yog hu ua solder block. Cov khoom xyaw no yog cov resins thiab pigments, cov xim ntsuab yog xim ntsuab, tab sis nrog kev txhim kho ntawm cov cuab yeej siv niaj hnub no, tau txuas mus rau ntau yam xim. Nws tsis txawv ntawm cov xim zoo nkauj. Ua ntej soldering yog luam tawm ntawm lub rooj tsavxwm Circuit Court, solder kuj yog muab tshuaj txhuam thiab ntws. Tom qab luam tawm ntawm lub rooj tsav xwm hauv Circuit Court, cov resin hardens vim cua sov thiab nws thiaj li "kho." Lub hom phiaj ntawm kev tiv thaiv vuam yog los tiv thaiv lub rooj tsav xwm Circuit Court los ntawm ya raws, oxidation thiab plua plav. Qhov tsuas yog qhov chaw uas tsis tau them los ntawm cov thaiv thaiv feem ntau yog hu ua lub ncoo thiab siv rau kev muab tshuaj txhuam.
Feem ntau, peb xaiv ntsuab vim nws tsis khaus qhov muag, thiab nws tsis yog ib qho yooj yim rau kev tsim thiab tu cov neeg ua haujlwm saib PCB ntev. Hauv kev tsim, cov xim siv feem ntau yog daj, dub thiab liab. Cov xim yog pleev xim rau ntawm qhov chaw tom qab nws tau tsim.
Lwm qhov laj thawj yog tias cov xim siv feem ntau yog ntsuab, yog li lub Hoobkas muaj cov xim ntsuab ntau tshaj plaws, yog li tus nqi ntawm cov roj kuj tseem tsawg. Qhov no kuj yog vim tias thaum ua haujlwm rau PCB pawg thawj coj saib, cov xaim sib txawv tau yooj yim dua kom paub qhov txawv ntawm cov xim dawb, thaum xim dub thiab dawb yog qhov nyuaj rau pom. Yuav kom paub qhov txawv ntawm nws cov khoom qib, txhua lub Hoobkas siv ob xim kom paub qhov txawv ntawm high-end series los ntawm qis-kawg series. Piv txwv li, Asus, lub tuam txhab motherboard lub computer, lub rooj tsav xwm daj yog qis kawg, blackboard yog siab kawg. Yingtai lub rebound yog high-end, thiab ntsuab board yog qis-kawg.
1. Muaj cov cim qhia ntawm lub rooj tsav xwm Circuit Court: pib ntawm R yog qhov resistor, qhov pib ntawm L yog inductor coil (feem ntau lub kauj yog qhov txhab ncig lub nplhaib hlau, qee qhov vaj tse raug kaw), qhov pib ntawm C yog qhov capacitor (siab cylindrical, qhwv hauv yas, electrolytic capacitors nrog cross indentation, tiaj nti capacitors), ob txhais ceg yog diodes, peb ceg yog transistors, thiab ntau ceg yog integrated circuits.
2, thyristor rectifier UR; Tswj Circuit Court muaj lub hwj huam mov rectifier VC; Inverter UF; Hloov UC; Inverter UI; Lub cev muaj zog M; Asynchronous lub cev muaj zog MA; Synchronous lub cev muaj zog MS; Dc lub cev muaj zog MD; Qhov txhab-rotor induction lub cev muaj zog MW; Squirrel tawb tsav MC; Hluav taws xob valve YM; Solenoid valve YV, thiab lwm yam.
3, txuas ntxiv nyeem txuas ib feem ntawm daim duab ntawm lub rooj tsav xwm tseem ceeb ntawm lub rooj tsav xwm lub rooj sib tham lub npe annotation cov ntaub ntawv.
