Kuenzanisa kwemutengesi kunofanira kutarisa pakuita: kugadzirwa kweimpedance inodzorwa, kudzora maitiro ekubatanidza, kuungana kwechikamu chemagetsi, kutsvaga maICS einterface, kuronga magadzirirwo uye kuyedzwa kweinterface yakawanda. Highleap inogona kusanganisa matanho iwayo pasi pepakeji imwe yekugadzira uku mutengi achiramba aine hunyanzvi hwekugadzira uye certification. Kune Docking Station PCB , port/power matrix yakatsanangurwa ndiyo nzira pfupi kubva pazita rechigadzirwa risinganyatsojeka kuenda kune quotation yakavimbika yekugadzira.
Poindi yekushandura yeRFQ
Tumira matrix yechiteshi uye bhajeti yemagetsi pamwe chete nePCB/BOM package. Highleap inogona kudzorera ongororo yekugadzira inoratidza nzira, chinongedzo, simba uye kuyedza zvinoenderana nemuenzaniso usati wagadzirwa.

Nzira yekuwana sei quote yePCBs
Ngatiite ongororo yeDFM/DFA kwauri tobva tadzoka kwauri nemushumo. Unogona kurodha mafaira ako zvakachengeteka kuburikidza newebhusaiti yedu. Tinoda ruzivo runotevera kuti tikupe mutengo:
-
- Gerber, ODB++, kana .pcb, spec.
- BOM rondedzero kana iwe uchida kusangana
- uwandu
- Kuchinja nguva
Kune masevhisi ePCBA, ndapota ipa BOM yako (Bhiri reZvinhu) uye chero mirairo yegungano. Isu tinopawo DFM/DFA ongororo yekukwidziridza zvigadziriso zvako zvekugadzira uye kusangana, kuve nechokwadi chekuita kwakatsetseka kwekugadzira.
