Emhlabeni wokukhiqiza izinto zikagesi, umthombo ovulekile we-PCBA (Printed Circuit Board Assembly) iwushintsho lomdlalo. Ishintsha indlela izinto ze-elekthronikhi eziklanywa ngayo, ezithuthukiswayo nezikhiqizwa ngayo. I-PCBA yomthombo ovulekile ingakhuthaza ukusebenzisana okungcono, ucwaningo kanye nokuqanjwa okusha ngaphakathi kwemboni. Ukusetshenziswa komthombo ovulekile we-PCBA kuvula amathuba amasha kubathuthukisi bezingxenyekazi zekhompuyutha, abakhiqizi nabashisekayo.
