Reflow soldering yog dab tsi?
Reflow soldering yog hais txog cua sov thiab melting lub solder paste pre-coated rau ntawm lub ncoo kom paub qhov hluav taws xob kev sib txuas ntawm cov pins los yog solder terminals ntawm cov khoom siv hluav taws xob pre-mounted rau ntawm lub ncoo thiab lub ncoo ntawm lub pcb, thiaj li mus cuag hluav taws xob. Lub hom phiaj ntawm soldering Cheebtsam ntawm PCB. Reflow soldering cia siab rau qhov kev txiav txim ntawm cov roj kub ntws ntawm cov pob qij txha. Lub colloidal flux tau dhau los ntawm lub cev cov tshuaj tiv thaiv nyob rau hauv qee qhov kub-kub roj ntws kom ua tiav SMD vuam; yog li ntawd nws yog hu ua "reflow soldering" vim hais tias cov roj circulates nyob rau hauv lub vuam tshuab los ua kom kub siab mus cuag welding. Reflow soldering feem ntau muab faib ua preheating cheeb tsam, cua sov cheeb tsam thiab txias cheeb tsam.
Wave soldering yog dab tsi?
Lub molten solder (lead-tin alloy) yog sprayed rau hauv lub solder yoj yuav tsum tau los ntawm tus tsim los ntawm lub hwj chim twj tso kua mis los yog electromagnetic twj tso kua mis, thiaj li hais tias cov luam ntawv board pre-ntsia nrog cov khoom kis tau los ntawm lub solder yoj kom paub lub soldering kawg los yog tus pin ntawm cov khoom siv Soldering ntawm txhua yam thiab hluav taws xob sib txuas rau cov ntawv luam tawm pads. Lub tshuab yoj soldering feem ntau yog tsim los ntawm txoj siv conveyor, qhov chaw ntxiv flux, thaj chaw ua ntej thiab lub qhov cub yoj tin, thiab nws cov khoom tseem ceeb yog solder bar.
Qhov sib txawv ntawm reflow soldering thiab yoj soldering
1. Wave soldering yog lub melting ntawm solder los ua ib tug solder yoj rau solder lub Cheebtsam; reflow soldering yog tsim los ntawm high-kub cua kub kom reflow molten solder rau solder lub Cheebtsam.
2. Cov txheej txheem yog txawv: yoj soldering yuav tsum tau tshuaj tsuag flux ua ntej, thiab tom qab ntawd mus los ntawm preheating, vuam, txias cheeb tsam, reflow soldering, muaj twb solder ntawm lub pcb ua ntej nws muab tso rau hauv lub cub tawg, tom qab soldering, tsuas yog coated. solder paste yog melted rau soldering, yoj soldering Lub sij hawm no, tsis muaj solder ua ntej lub pcb yuav muab tso rau hauv lub cub tawg, thiab lub solder yoj tsim los ntawm lub vuam tshuab kis tau cov solder ntawm lub ncoo yuav tsum tau soldered kom tiav cov soldering.
3. Reflow soldering yog tsim rau SMD cov khoom siv hluav taws xob, thiab yoj soldering yog tsim rau tus pin hluav taws xob cov khoom.
