Khadka kaarboon waxa lagu daabacaa oogada PCB-ga sidii daari si loogu xidho laba raadad PCB. Khadka kaarboon PCB, tan ugu muhiimsan waa tayada iyo caabbinta saliidda kaarboonka, Dhanka kale, Immersion silver PCB iyo Immersion tin PCB lama daabici karo saliid kaarboon, sababtoo ah waxay yihiin Oxidizing. Dhanka kale, booska ugu yar ee khadka waa inuu ka badan yahay 0.2 mm si ay u sahlanaato in la soo saaro oo la xakameeyo iyada oo aan lahayn wareegga gaaban.
Khadka kaarboon waxa loo isticmaali karaa xidhiidhada kiiboodhka, xidhiidhada LCD iyo boodayaasha. Daabacaadda waxaa lagu sameeyaa khad kaarboon ah.
Habka Saliidda Kaarboon ee Gaarka ah
Waxaan aaminsanahay in saliidda Kaarboon PCBA ay bixiso isku-dar aan laga adkaan karin oo tayo, waxqabad, iyo qiimo ah. Haddii aad hayso wax su'aalo ah oo ku saabsan alaabtan ama aad jeceshahay inaad wax badan ka barato sida ay uga faa'iidaysan karto ganacsigaaga, fadlan ha ka waaban inaad nala soo xidhiidho. Waxaan u heellannahay inaan bixinno adeegga macaamiisha oo aad u wanaagsan iyo inaan ka caawinno macaamiisheena inay gaaraan yoolalka ganacsigooda.
Waad ku mahadsan tahay inaad tixgelisay saliidda Kaarboon PCBA. Waxaan rajeyneynaa fursad aan kula shaqeyno oo aan kugu caawinno inaad gaarto guul.
