Highleap inogona kutora chikamu chekugadzirwa kwemagetsi uye kuona chero fixture kana calibration dependencies. Kune Drawing Tablet PCB , kujeka ikoko kunogadzira nzira yakasimba yekugadzira kupfuura kutaura tekinoroji yekunzwa isina rutsigiro kana zvirevo zve generic pressure-level.
Poindi yekushandura yeRFQ
Goverana dhizaini ye sensor-interface uye maitiro ekuyedza pen anotsanangurwa nemutengi kana maitiro ekugadzirisa nePCB package. Highleap inogona kuongorora kudzokorora kwekubatanidza, mashandiro ekubatanidza uye kuyedza kugona kwekushandisa uku ichichengetedza hunyanzvi hwekuona zviri mukati mayo.

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.
