Lub hauv paus ntsiab lus ntawm kev ua haujlwm zoo thiab ntau yam khoom siv hlau
Lub tshuab hluav taws xob muaj txiaj ntsig zoo tshaj plaws, uas siv cov kev sib txuas tshwj xeeb raws li kev tswj xyuas, tuaj yeem ua rau lub zog hluav taws xob ntawm cov hluav taws xob soldering hlau tsis tu ncua ntawm 0 thiab 50W, thiab tseem muaj ntau yam kev tshawb nrhiav. Lub tshuab hluav taws xob hluav taws xob no ua ke nrog cov haujlwm ntawm kev tshawb nrhiav thiab vuam, thiab muaj cov yam ntxwv ntawm kev ua haujlwm siab, txuag hluav taws xob, thiab txuas lub neej ntev.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm kev ua haujlwm tau zoo thiab muaj ntau yam hluav taws xob soldering hlau
Kev tswj Circuit Court ntawm no soldering hlau yog qhia nyob rau hauv daim duab saum toj no. Lub IC (CS929) nyob rau hauv daim duab yog ib tug integrated Circuit Court thaiv tshwj xeeb uas tsim rau no hom ntawm soldering hlau. Nws muaj hwj chim tswj t teeb liab nrhiav kom tau thiab lwm yam circuits. Daim duab kuj tseem muab cov npe ntawm txhua tus pin ntawm kev sib xyaw ua ke. Ib qho kawg ntawm AC 220V fais fab mov yog input rau lub hwj chim tswj Circuit Court nyob rau hauv lub integrated Circuit Court los ntawm tus pin ④ ntawm IC, thiab ces xa mus rau lub soldering hlau los ntawm tus pin ⑤ thiab sab nraud potentiometer W. Hloov qhov tsis kam ntawm W tuaj yeem hloov cov zis tawm. zog.
Lub ⑦ tus pin ntawm IC yog lub input davhlau ya nyob twg ntawm lub teeb liab nrhiav pom. Thaum hloov K ntawm DC lub zog hluav taws xob 3V qhib, qhov kev tshawb pom lub teeb liab tawm tswv yim los ntawm ⑦ tus pin tau nthuav dav los ntawm lub voj voog sab hauv thiab tom qab ntawd tso tawm los ntawm ② thiab ⑧ pins. Nyob ntawm seb lub teeb liab tso zis tuaj yeem tsav lub teeb-emitting diode Los ntawm emitting lub teeb, koj tuaj yeem txiav txim siab qhov zoo ntawm capacitors, resistors, diodes, thiab transistors hauv Circuit Court, nrog rau kev txuas ntxiv ntawm cov kab hluav taws xob.
Qhov zoo ntawm kev ua haujlwm zoo thiab ntau yam khoom siv hlau
1. Nrog lub zog kho tau, ib qho hlau tuaj yeem hloov tau peb cov khoom lag luam uas muaj 20W, 30W thiab 50W.
2. Lub hwj chim tuaj yeem hloov tau txhua lub sijhawm raws li qhov loj ntawm cov khoom siv vuam thiab qhov kub thiab txias los tiv thaiv cov hlau nplaum los ntawm kev kub dhau thiab txo qhov tsim ntawm oxide txheej, yog li ua kom cov tin noj muaj peev xwm ntawm cov hlau soldering. lub tswv yim, txhim kho qhov zoo ntawm cov khoom siv vuam thiab vuam ceev, thiab tib lub sij hawm nws plays lub luag hauj lwm ntawm kev txuag hluav taws xob thiab txuas lub neej.
3. Kev ua haujlwm vuam tiag tiag feem ntau koom nrog kev kuaj xyuas ua ntej ntawm kev txuas ntxiv ntawm cov xov hlau, qhov zoo ntawm cov khoom siv, muaj qhov hloov pauv tam sim no, thiab lwm yam. Vim li no, tam sim no tsis muaj hluav taws xob soldering hlau nrog kev tshawb pom muaj nuj nqi. Cov hlau soldering no muaj ntau yam kev ntsuas kev ua haujlwm thiab yog ib qho khoom siv hluav taws xob uas sib koom ua ke tshawb nrhiav thiab vuam.
