I-Highleap ingagcina isisekelo sokukhiqiza sihambisana nalawo masango: i-BOM evunyiwe, amamaski okumboza, izinhlobo zokuxhuma/zekhebula, i-firmware, amarekhodi okulinganisa, amalebula kanye nokupakishwa. Lokhu kubaluleke kakhulu kwi-OEM kunesimangalo esijwayelekile sokuthi wonke amabhodi esiteshi sezulu asebenzisa izinto ezifanayo noma inani lezendlalelo.
Ukuvezwa Kwensimu Kuyingxenye Yencazelo Yokukhiqiza
I-RFQ elungele insimu kufanele ixhume izinto zikagesi ezimweni zokuvezwa. Thumela i-Gerber/ODB++, amanothi okukhiqiza, i-BOM, ukukhetha nokubeka, imidwebo yokuhlanganisa, uhlu lwezinzwa, amafayela e-enclosure/vent, i-external sensor interfaces, izidingo zekhebula, imaski yokumboza, imininingwane yebhethri noma yelanga, i-firmware, inqubo yokulinganisa/yokuhlola kanye nobuningi obulindelekile bokuhlola nokukhiqiza.
I-Highleap ingakhiqiza i-PCB kanye ne-PCBA, ithole izingxenye ezivunyiwe, ihlanganise izixhumi kanye nezici zokuvikela, ihlele ibhodi futhi isebenzise ukuhlolwa kokusebenza okuchazwe yikhasimende. Indawo yokushayela ibalulekile uma ifakiwe ekucushweni kwensimu okuhlosiwe futhi isetshenziselwa ukuqinisekisa ukulawulwa kokujiya, ukuvala izixhumi, ukuzifudumeza, ukuchayeka kwenzwa kanye nokuziphatha kwamandla ngaphambi kokuba isakhiwo siqandiswe.
Isimo sezulu asikho ngaphandle kwencazelo yokukhiqiza—yingakho umkhiqizo ukhona. Isisekelo sokukhiqiza kufanele silondoloze izimo zomzimba ezivumela inzwa ngayinye ukuthi ilinganise lokho ikhasimende elikuhlosile, kuyilapho i-PCB kanye nenqubo yokuhlanganisa zihlala zihambisana kusukela ekufakweni kwensimu eyodwa kuya kwenye.

Ungasithola kanjani isilinganiso sama-PCB
Ake siqhube ukuhlaziywa kwe-DFM/DFA bese sibuyela kuwe nombiko. Ungalayisha amafayela akho ngokuphephile ngewebhusayithi yethu. Sidinga ulwazi olulandelayo ukuze sikunike isilinganiso:
-
- Gerber, ODB++, noma .pcb, spec.
- Uhlu lwe-BOM uma udinga ukuhlangana
- Ubuningi
- Isikhathi sokushintsha
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.
