PCBA Awondisman Komisyon Konsèy soude Disk Nwa Pwoblèm se yon tablo sikwi pi komen move fenomèn, sa ki lakòz PCBA soude disk nwa pou plizyè rezon, men anjeneral ki te koze pa rezon sa yo:

1, pad oxidation: If the PCBA pad is exposed to humidity for a long time, it will cause the surface of the pad to oxidize, forming an oxide film on the surface of the pad, resulting in black, therefore, when storing PCBA, attention should be paid to keeping the environment dry, and at the same time, PCBA should be vacuumed in time to avoid its long-term exposure to the air!

2, welding process problems: in reflow welding or wave soldering, if the welding temperature is too high or the welding time is too long, it will also lead to the oxidation of the welding pad black phenomenon, this reaction is usually due to the welding temperature exceeds the recommended temperature range of the solder, resulting in accelerated oxidation process, so in the welding process must be in accordance with the operating specifications for welding!

3, pwoblèm soude: soude jeneralman refere a keratin nan soude, fèblan, bon jan kalite soude se yon bon bagay oswa move, si itilize nan soude bon jan kalite pòv, pral tou fè soude a nan sibstans ki sou danjere ak enpurte lage, ki kapab lakòz yon pad nwa, se konsa, nan chwa pou yo soude, nou dwe evite itilize nan bon jan kalite ki ba-soude!

4, Netwayaj Pwoblèm: Anjeneral pale, nan ka a nan itilize nan flux nesesè yo netwaye tablo a, yo nan lòd yo retire rezidi a flux sou pad la, epi si rezidi a flux pa konplètman retire, Lè sa a, sa yo flux rezidyèl ka degrade oswa carbonize nan tanperati ki wo, se konsa ke pad la parèt nwa. Se poutèt sa, netwaye alè apre soude se trè nesesè!

5, Pwoblèm Component: Si bon jan kalite a nan eleman yo elektwonik se pa bon, oswa materyèl la nan PIN la eleman se move, li ka tou mennen nan fenomèn nan disk soude nwa, se konsa, lè w ap chwazi eleman elektwonik, nou dwe chwazi bon jan kalite bon kalite asire ke bon jan kalite a nan kouch la ak materyèl PIN nan konpozan yo kalifye.

Pi wo a la se rezon prensipal pou PCBA soude plato nwa, ak dapre diferan rezon, nou ka chwazi tou mezi yo amelyorasyon ki koresponn, konsa tankou efektivman diminye pwoblèm nan nan plato PCBA soude nwa, amelyore bon jan kalite a nan pwodwi!
