Perforated soldering (pins txuas nrog PCB board los ntawm perforations)
Cov kauj ruam yog thawj zaug hla cov pins sib txuas ntawm cov khoom sib txuas los ntawm PCB lub rooj tsavxwm, tom qab ntawd siv lub taub hau ntawm cov hlau tin los ntswj qee cov rosin, thiab tom qab ntawd muab cov hlau txuas ze rau cov pins kom tau soldered ntawm PCB board (feem ntau. rau 1 vib nas this), thiab tom qab ntawd ces kov lub tin hlau stained nrog rosin rau cov hlau soldering (tso nws nyob rau hauv lub ntsis ntawm lub soldering hlau los yog nyob rau hauv parallel nrog lub ntsis ntawm lub soldering hlau, tsis yog nyob rau sab saum toj ntawm lub ntsis ntawm lub soldering hlau. ), cov tin hlau yuav yaj nyob rau hauv qhov kub thiab txias ntawm qhov kawg ntawm cov hlau soldering thiab cia li qhwv cov pins nyob rau hauv cov duab ntawm cov tee dej Nrog lub PCB board cheeb tsam, sai sai tshem tawm cov tin hlau tom qab melting, tab sis lub sij hawm no, tsis txhob. tshem tawm lub hau ntawm cov hlau soldering, tuav lub ntsis ntawm cov hlau soldering nyob rau hauv thawj txoj hauj lwm li 1 thib ob, cia lub solder tag nrho yaj thiab ntws nyob ib ncig ntawm lub ncoo thiab nyob ntawm tej, thiaj li hais tias nws yog zoo meej ua tiav tag nrho cov txheej txheem vuam.
Yog lawm, tom qab soldering, yog tias cov hlau lead ntawm cov khoom siv tau ntev dhau lawm, cov hlau lead ntau dhau yuav tsum tau txiav tawm.
