Tuam txhab Kev paub
Yog vim li cas rau gloss tsis zoo ntawm cov pob qij txha nyob rau hauv SMT nti ua
Hauv SMT vuam thev naus laus zis, ntau tus neeg siv khoom feem ntau muaj qhov xav tau rau qhov ci ntsa iab ntawm cov pob qij txha. Tom qab tag nrho, qhov ci ntsa iab ntawm cov pob qij txha yuav ua rau peb kaj siab. Nyob rau hauv cov txheej txheem ntawm SMT nti ua, nws tsis tau lees tias qhov ci ntsa iab ntawm txhua qhov taw tes tuaj yeem ncav cuag qhov ci ntsa iab. Yog li dab tsi yog vim li cas rau qhov tsis txaus gloss ntawm cov pob qij txha hauv SMT nti ua?
1. The tin powder in the solder paste has oxidation appearance.
2. The flux itself in the solder paste has additives that form a matting effect.
3. The preheating temperature of reflow soldering is low in SMD processing, and there are residues that are not easy to evaporate on the surface of the solder joints.
4. After soldering, there are rosin or resin residues on the appearance of the solder joints. This is a phenomenon that is often seen in actual operations, especially when rosin-type solder paste is used. The spot is slightly brighter, but the presence of its residue often affects this effect, especially in larger solder joints or IC pins; if it can be cleaned after soldering, the solder joint gloss should be improved.
5. Txij li thaum tsis muaj tus qauv rau qhov ci ntsa iab ntawm cov pob qij txha, yog tias cov khoom tom qab soldering tsis muaj nyiaj solder paste piv nrog cov tom qab soldering nrog cov nyiaj solder paste, nws yuav muaj qee qhov kev ncua deb, uas xav kom cov neeg siv khoom xaiv cov tshuaj txhuam hniav. yuav tsum qhia meej lawv cov kev cai sib koom ua ke rau tus neeg muag khoom.
