Dab tsi yog qhov txawv ntawm Reflow Soldering thiab Wave Soldering?

Reflow soldering yog dab tsi?
Reflow soldering yog hais txog kev sib txuas hluav taws xob ntawm cov pins lossis cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob ua ntej tso rau ntawm cov ntaub qhwv nrog cov ntaub qhwv ntawm PCB los ntawm cua sov thiab melting lub solder pre-coated ntawm lub ncoo, thiaj li ua tiav cov hluav taws xob sib cuam tshuam ntawm cov khoom. cov khoom siv hluav taws xob. Lub hom phiaj ntawm welding Cheebtsam ntawm PCB board. Reflow soldering cia siab rau qhov kev txiav txim ntawm cov cua kub ntawm cov pob qij txha. Lub colloidal flux lub cev reacts nyob rau hauv ib tug tej yam kub-kub airflow kom 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 ib tug hluav taws xob twj tso kua mis los yog ib tug electromagnetic twj tso kua mis, thiaj li hais tias cov luam ntawv board pre-installed nrog cov khoom dhau los ntawm cov khoom yoj kom paub lub soldering terminal los yog txhuas. ntawm cov khoom. Soldering cov neeg kho tshuab thiab hluav taws xob kev sib txuas ntawm ko taw thiab cov ntaub ntawv luam tawm. Lub tshuab nthwv dej feem ntau yog tsim los ntawm txoj siv conveyor, ib qho chaw ntxiv flux, thaj chaw ua ntej cua sov thiab lub qhov cub hluav taws xob. Nws cov khoom tseem ceeb yog solder strips.

Qhov sib txawv ntawm reflow soldering thiab yoj soldering
1. Wave soldering yog thaum molten solder tsim ib yoj yoj rau solder Cheebtsam; reflow yog thaum high-temperature kub cov ntaub ntawv reflow molten solder rau solder Cheebtsam.
2. Cov txheej txheem sib txawv: Wave soldering yuav tsum tau txau cov flux ua ntej, thiab tom qab ntawd los ntawm preheating, soldering, txias cheeb tsam, thiab reflow soldering. Muaj twb tau solder ua ntej lub PCB muab tso rau hauv lub qhov cub. Tom qab soldering, lub coated tin tone tsuas yog melted rau soldering. Wave soldering Thaum lub PCB muab tso rau hauv lub qhov cub, tsis muaj solder. Lub vuam yoj tsim los ntawm lub tshuab welding kis tau tus welder ntawm cov ntaub qhwv uas yuav tsum tau welded kom tiav qhov vuam.
3. Reflow soldering yog tsim rau chip electronic Cheebtsam, thiab yoj soldering yog haum rau pin electronics.
