Dab tsi yog ua kom muaj kab nrib pleb hauv PCBA solder pins
Oct 01, 2019
Raws li qhov ntom ntawm cov khoom hluav taws xob sib dhos tau nce siab dua thiab siab dua, cov txheej txheem cov txheej txheem rau PCBA sib dhos tau dhau los thiab ntau dua. Thaum lub sijhawm PCBA cov txheej txheem soldering, cov kev xav tsis zoo kuj tau pib nce. Ntawm lawv, tin cracking yog ib qho teeb meem feem ntau ntawm PCBA.
Cov kab nrib pleb hauv PCBA cov txheej txheem soldering yog feem ntau los ntawm cov hauv qab no.
1. Lub thoob qij ua ke tau tawg vim muaj qhov cuam tshuam los ntawm sab nraud quab yuam.
2. Thaum ua tiav PCBA tom qab ua tiav vuam, vim hais tias txiav cov leeg tsis ntse, qhov tshwm sim rub tawm thaum txiav tus taw, uas ua rau cov kab nrib pleb hauv cov sib xyaw taw thiab cov ntsiab lus tin.
3. Vim tias tsis tshua muaj tin, vuam lub zog ntawm vuam chaw tsis txaus, uas ua rau kom muaj kev yooj yim tawg.
Cov hmoov nplej tawg tsim thaum lub sijhawm PCBA vuam tsim kuj tseem muaj kev sib raug zoo nrog qhov zoo ntawm cov khoom siv vuam. Kev ua tsis tau zoo tseem yuav ua rau lub firmness ntawm cov ham. Nyob hauv qab hluav taws xob ntawm sab nraud quab yuam, cov kab nrib pleb zoo li yuav tshwm sim.
