Ifektri kufanele icaphune isakhiwo esikhishwe futhi iphakamise izinguquko kuphela uma kukhona ukukhiqizwa okucacile noma isizathu sezindleko.

Yini eyenza i-USB-C hub PCBA “ilungele ukukhiqizwa”?

Umklamo owamukelwe kufanele ube ne-PCB stack-up eqandisiwe, i-BOM evunyiwe kanye nezinye izindlela, izinqubo zokuxhuma/zomshini, iphakheji yokuhlela, inqubo yokuhlola, i-variant matrix kanye nokuphambuka okubhaliwe. Lezo zilawuli zibaluleke kakhulu ekuphindaphindeni kunesimangalo esijwayelekile sokuthi ifektri inolwazi ngemikhiqizo ye-USB-C.
