Dab tsi yogreflow qhov cub?
Reflow soldering tshuab yog los yaj lub solder paste pre-coated ntawm lub solder ncoo los ntawm cua sov kom paub qhov hluav taws xob interconnection ntawm tus pins los yog vuam xaus ntawm hluav taws xob Cheebtsam pre-mounted rau lub solder ncoo thiab solder ncoo ntawm lub PCB, thiaj li mus ua tiav lub hom phiaj ntawm vuam cov khoom siv hluav taws xob ntawm PCB pawg thawj coj saib.SMT vuam tshuabyog raws li lub luag hauj lwm ntawm cov roj kub ntws ntawm cov sib koom ua ke, gelatinous flux nyob rau hauv ib qho kev kub siab airflow lub cev cov tshuaj tiv thaiv kom ua tiav SMD vuam;Yog li hu ua "reflow cub", vim hais tias cov roj hauv lubtshuab solderingcirculating ntws los ua kom kub siab rau vuam.Reflow qhov cub feem ntau muab faib ua preheating zone, cua sov cheeb tsam thiab cua txias.
Dab tsi yog yoj soldering tshuab?
Melt lub soft solder (lead tin alloy), los ntawm lub twj tso kua mis hluav taws xob los yog electromagnetic twj tso kua mis ntws mus rau hauv tus tsim yuav tsum tau ntawm lub solder yoj, thiaj li hais tias lub board luam ntawv pre-nruab nrab ntawm cov khoom los ntawm lub solder yoj, mus cuag cov neeg kho tshuab thiab hluav taws xob kev twb kev txuas. nruab nrab ntawm qhov chaw ntawm vuam kawg los yog pins thiab luam board vuam ncoo mos brazing.Wave soldering tshuab yog tsim los ntawm kev thauj siv, flux ntxiv cheeb tsam, preheating cheeb tsam thiab yoj tin rauv, nws cov khoom tseem ceeb yog solder bar.
Dab tsi yog qhov txawv ntawm reflow thiab yoj soldering?

1. Wave soldering yog molten solder los ua ib lub yoj yoj rau cov khoom siv vuam;Reflow qhov cub yog soldering ntawm cov khoom los ntawm cov cua kub sib sau ua cov reflow melting solder.

2. Cov txheej txheem yog txawv: tshuaj tsuag hmoov txhuv nplej siab soldering flux, dua tom qab preheating, vuam, txias cheeb tsam, reflow soldering, yav tas los muaj solder ntawm lub PCB rauv, tom qab welding yog txheej ntawm solder paste melting welding, yoj soldering, yav tas los tau ua. Tsis yog solder ntawm PCB rauv, vuam tshuab ntawm cov yoj yoj solder txheej tiav vuam rau vuam vuam phaj.

3. Reflow qhov cub yog tsim rau SMT cov khoom siv hluav taws xob, yoj soldering yog tsim rau tus pin hluav taws xob cov khoom.
