Puas yog ib tug diode txuas nrog koob nrog solding hlau ua tiav lub hom phiaj txias?
Lub dc hluav taws xob muab khoom ncaj qha ncaj qha rau cov hlau sib dhos. Vim tias tsis muaj qhov tsis txaus thiab tswj cov voj voog, qhov kub tsis tuaj yeem khaws cia tsis tu ncua thiab yuav sib txawv nrog thaj chaw soldering. Tsawg qhov kub yuav ua rau cov dej nrawm nrawm, thaum kub siab yuav ua rau cov cam hlau ua rau oxidize dhau lawm, ua rau tsis ua tiav. Txoj kev zoo tshaj plaws los daws cov teeb meem ntawm qhov kub tsis tu ncua yog kom pom qhov ntsuas kub thiab txias thiab tswj cov voj voog. Yog tias siv cov hlau tsis tu ncua yog siv rau kev hloov kho, vim tsis muaj qhov tsis muaj qhov ntsuas kub, nws tsis tuaj yeem hloov mus rau qhov kub thiab txias los ntawm txo lub siab.
Ordinary diodes, depending on the model, have a forward voltage drop of around {{0}}.7V for ordinary rectifier diodes, and even lower for Schottky diodes. Yog tias cov hlau soldering powered los ntawm AC fais fab, vim tias cov nqi voltage, vim tias cov nqi voltage yuav tau txiav txim siab tom qab lub zog rectified los ntawm Diode. Txawm li cas los xij, rau DC voltage, qhov zoo tshaj plaws voltage poob ntawm ib qho diode tsuas yog 0.7v, thiab qhov kev txo qis ntawm voltage txo qis heev, uas tsis muaj qhov cuam tshuam tseem ceeb rau qhov ntsuas kub.
Kom txo qis qhov kub, tib txoj kev yog kom txo qis ntawm cov hluav taws xob. Muaj ob txoj hauv kev los txo voltage, ib qho yog hloov cov ntaub ntawv hluav taws xob ntawm cov zis hauv lub zog hluav taws xob hauv lub zog, uas yuav tsum tau muaj qee qhov kev sib tw thiab lub hauv paus. Lwm txoj hauv kev yog siv cov tiav lawm DC tau hloov kho volashabry txo cov qauv los hloov cov zis hluav taws xob los ntawm kev ua tau zoo. Thiab nws tuaj yeem hloov kho nrog cov khaub noom tuaj, ntxiv cov khoom sib xyaw ua ke rau cov hlau sib dhos, thiab cia li txo qis ntawm cov hlau tso rau hauv.
