Kev ceev faj rau phau ntawv hluav taws xob soldering hlau vuam
1) Master lub sijhawm cua sov kom zoo
Preheat lub workpiece. Tsim kom muaj dej ntws zoo thiab ntub dej yuav tsum tau preheating. Pads, qhov, thiab cov khoom siv pins nrog cov yam ntxwv zoo solderability yuav pab tsim cov pob qij txha zoo hauv lub sijhawm luv tshaj plaws.
Ntawm qhov kub siab, lub sij hawm luv luv yog tus yuam sij kom tsis txhob muaj kev puas tsuaj rau lub substrate, kev puas tsuaj rau kev sib txuas ntawm cov ntaub qhwv thiab cov substrate, thiab cov hlau loj heev rau cov hlau loj. Solder me ntsis raug rov qab Kub Cycles saum toj liquefaction kub ntawm Tg ntawm solder thiab / los yog substrate yuav raug kev txom nyem degradation ntawm kev cia siab rau tsub zuj zuj.
Txoj kev yog ua kom tiav qhov vuam taw tes hauv tsawg dua 5 vib nas this, nyiam dua nyob ib ncig ntawm 3 vib nas this. Lub sijhawm no suav nrog tag nrho cov haujlwm tsim nyog yuav tsum tau ua kom muaj kev sib txuas, thiab lub sijhawm luv dua, qhov zoo dua, thaum ua kom ntseeg tau tias cov khoom siv ntub dej ntawm cov solder.
2) Khaws qhov kub kom haum
Khaws lub taub hau ntawm lub taub hau rau hauv qhov kub thiab txias. Qhov kev paub dav dav yog tias qhov kub ntawm lub taub hau ntawm lub taub hau yog 50 degree siab dua li qhov kub ntawm cov hlau, uas yog qhov tsim nyog dua.
3) Nws tsis raug siv rau kev siv dag zog rau kev sib koom tes nrog cov hlau soldering. Nws yuav ua rau kev puas tsuaj rau lub welment. Piv txwv li, cov ntsiab lus vuam ntawm Potentiometer, hloov pauv thiab cov khoom sib txuas feem ntau tau kho ntawm cov khoom yas, thiab cov txiaj ntsig ntawm kev siv quab yuam yuav ua rau cov khoom tsis ua haujlwm.
Tsis tas li ntawd, kev siv hluav taws xob soldering hlau belongs rau kev ua haujlwm siab, thiab nws yuav tsum tau them sai sai rau kev siv hluav taws xob kom zoo.
Ntau lub tshuab hluav taws xob hluav taws xob muaj peb lub terminals, ob qho tib si txuas nrog cov tub ntxhais hlau txuas rau 220V AC lub zog hluav taws xob, thiab lwm qhov yog txuas nrog lub plhaub hlau nplaum ua lub chaw tiv thaiv hauv av rau txuas rau hauv av xaim. Rau kev nyab xeeb yog vim li cas, nws yog qhov zoo tshaj plaws los siv ib lub multimeter los txheeb xyuas seb cov tub ntxhais hlau soldering puas raug txiav los yog sib xyaw ua ntej siv.
Qhov tsis kam ntawm cov tub ntxhais hlau rau ib txwm 20-30W hluav taws xob soldering hlau yog 1500-2500 ohms.
