Kev daws rau kub khiav ntawm qhov kub thiab txias hluav taws xob soldering hlau
Sab hauv ntawm qhov kub thiab txias tsis tu ncua hluav taws xob soldering hlau txais lub siab Curie kub sawb zoo li PTC qhov kub thiab txias txias, nruab nrog cov qauv thermal conductivity fastening. Tus yam ntxwv yog superior rau cov tsoos hluav taws xob hlau soldering hlau cores, nrog ceev cua sov, lub zog txuag, txhim khu kev qha lag luam, kev pab lub neej ntev, thiab tus nqi qis. Tsawg voltage PTC cua sov cores tuaj yeem siv rau hauv thaj chaw, ua kom yooj yim rau kev txij nkawm ua haujlwm.
Kev daws rau kub khiav ntawm qhov kub thiab txias hluav taws xob soldering hlau
Qhov kev ua haujlwm tsis zoo ntawm qhov ntsuas kub tsis tu ncua hluav taws xob hluav taws xob yog qhov kub thiab txias, uas ua rau qhov kub ntawm cov hlau soldering siab dhau lawm. Ntawm ib sab, nws ua rau kub-kub oxidation ntawm lub taub hau hlau soldering (soldering tin kuj oxidized tib lub sijhawm); Ntawm qhov tod tes, vuam ntawm qhov kub thiab txias tuaj yeem hlawv cov khoom hluav taws xob tau yooj yim. Thaum lub tshuab hluav taws xob siv hluav taws xob ua haujlwm ntawm qhov kub siab ntev ntev, nws kuj yog ib qho yooj yim los ua kev puas tsuaj rau nws cov hluav taws xob hauv Circuit Court, ua rau tsis muaj kev tswj xyuas tas li thiab txawm tias siv tsis tau. Thaum lub sij hawm kev soj ntsuam txhaum, nws yuav pom tias zawv zawg sib cuag ntawm qhov kub thiab txias regulating resistor R2 yog oxidized thiab ua rau cov neeg pluag kev sib cuag, uas yog sib npaug rau qhov kub thiab txias tau hloov mus rau qhov siab tshaj plaws sab sauv txwv, uas ua rau ib tug kub ntawm soldering hlau. Muaj ob qho laj thawj tseem ceeb rau qhov no: ua ntej, thaum lub tshuab hluav taws xob ua haujlwm, nws hloov ib feem ntawm cov cua sov mus rau tus tuav ntawm cov hlau soldering (hauv Circuit Court), ua rau qhov kub thiab txias ntawm qhov chaw ua haujlwm ntawm lub voj voog. Tom qab ib lub sij hawm, nws yog ib qho yooj yim los ua oxidation ntawm R2 tus tsiv hu; Qhov thib ob yog tias tam sim no limiting resistor R1 nyob rau hauv rectification thiab filtering Circuit Court dissipates tshav kub, ua rau ib qho kev nce nyob rau hauv lub chaw ua hauj lwm kub ntawm lub Circuit Court thiab yooj yim ua rau oxidation ntawm lub R2 mus sib cuag.
Txhawm rau tiv thaiv qhov tshwm sim ntawm qhov tsis raug, ob txoj hauv qab no rau kev hloov kho lub voj voog raug npaj
(1) Hloov kho cov resistor R2 nrog ib qho kev tiv thaiv ruaj khov: Ua ntej, kho R2 kom ncav cuag qhov ntsuas kub zoo rau kev siv cov hlau soldering ib txwm, tom qab ntawd ntsuas tus nqi ntawm R2 thiab hloov nws nrog cov khoom ruaj khov.
(2) Hloov lub voj voog rectifier: Cov qauv hauv Circuit Court yog qhia hauv daim duab hauv qab no.
