- Isikhathi sokushintsha
Ngokungeziwe ekwenziweni kwe-PCB, sinikeza uhla olubanzi lwezinsizakalo ze-elekthronikhi, okuhlanganisa i-PCB design, i-PCBA, nezixazululo ze-turnkey. Kungakhathaliseki ukuthi udinga usizo ngokwenza i-prototyping, ukuqinisekiswa kwedizayini, ukuthola ingxenye, noma ukukhiqizwa ngobuningi, sihlinzeka ngosekelo olusuka ekupheleni ukuze siqinisekise impumelelo yephrojekthi yakho.
Ngezinsizakalo ze-PCBA, sicela unikeze i-BOM yakho (I-Bill of Materials) kanye nanoma yimiphi imiyalelo ethile yomhlangano. Siphinde sinikeze ukuhlaziya kwe-DFM/DFA ukuze uthuthukise imiklamo yakho ukuze yenziwe futhi ihlanganiswe, ukuqinisekisa inqubo yokukhiqiza eshelelayo.
