Infrared + hawo kulul oo dib u qulqulaya alxanka
Bartamihii 1990-aadkii, waxaa jiray isbeddel lagu wareejinayo infrared + kulaylka hawada kulul ee dib-u-socodka alxanka ee Japan. Waxaa lagu kululeeyaa 30% fallaadho infrared iyo 70% hawo kulul sida kuleyl. Foornada dib-u-soo-celinta hawada kulul ee infrared waxay si wax ku ool ah isugu daraysaa faa'iidooyinka dib-u-soo-kabashada infrared iyo hawo kulul oo qasab ahSii akhri -
Waa maxay habaynta PCBA?
Habaynta PCBA waa badeeco dhammaatay oo ah guddiga PCB oo qaawan kadib balastar SMT, PIP plug-in iyo PCBA test, hubinta tayada iyo habka isu-ururinta, oo loo yaqaan PCBA.
