Nigute Watsindira Prototype Yihuta-Datacom PCB

Intangiriro:

Gukoresha prototyping yumuzingo wacapwe (PCB) hamwe nubushobozi bwihuse bwo gutumanaho amakuru birashobora kuba umurimo utoroshye. Ariko, hamwe nuburyo bwiza nubumenyi, birashobora kandi kuba ibintu bishimishije kandi bihesha ingororano.Muri iyi nyandiko ya blog, tuzasesengura intambwe-ku-ntambwe yo gukora prototyping PCB ishobora gukora neza itumanaho ryihuse.

Wige ibisabwa:

Intambwe yambere mugukwirakwiza PCB hamwe namakuru yihuta yamakuru yamakuru ni ukumva neza ibisabwa. Reba ibintu nkigipimo gisabwa cyo kohereza amakuru, protocole nibipimo bizakoreshwa, hamwe n urusaku nimbogamizi umuziki ugomba kwihanganira. Uku gusobanukirwa kwambere kuzakuyobora mubikorwa.

Hitamo ibice bikwiye:

Kugirango umenye amakuru yihuse itumanaho, ni ngombwa guhitamo ibice bikwiye bya PCB. Shakisha ibice bifite igisubizo kinini kandi gisubiza hasi. Ni ngombwa gusubiramo urupapuro rwerekana ibisobanuro hamwe nibisobanuro witonze kugirango urebe ko byujuje ibyo usabwa. Byongeye kandi, tekereza gukoresha ibice bigezweho nka transcevers yihuta cyangwa serializers / deserializers (SerDes) kugirango utezimbere imikorere.

Gushushanya imiterere ya PCB:

Imiterere ya PCB igira uruhare runini mugushikira amakuru yihuse. Witondere ubudakemwa bwibimenyetso, uburebure buhuye no kugenzura inzitizi. Koresha tekinike nkibimenyetso bitandukanye, guhuza umurongo, no kwirinda kugoreka gukabije kugirango ugabanye kugoreka ibimenyetso no kunyura. Byongeye kandi, tekereza gukoresha indege nubutaka kugirango uzamure imikorere muri rusange kandi ugabanye amashanyarazi (EMI).

Igishushanyo n'isesengura:

Mbere yo gukomeza iterambere rya prototype, igishushanyo kigomba kwigana no gusesengurwa. Koresha ibikoresho bya software nka SPICE (Porogaramu ya Integrated Circuit Emphasis Simulation) cyangwa simulator ya electronique kugirango ugenzure imikorere yubushakashatsi bwawe. Shakisha ibibazo byose bishobora kugaragara nko kwerekana ibimenyetso, kurenga ku gihe, cyangwa urusaku rukabije. Guhindura ibikenewe mugihe cyo gushushanya bizatwara igihe kandi bigabanye ibyago byo gutsindwa mugihe cya prototyping.

Gukora prototypes ya PCB:

Igishushanyo kimaze kurangizwa no kugenzurwa hifashishijwe kwigana, prototype ya PCB irashobora gukorwa. Igishushanyo mbonera gishobora koherezwa muri sosiyete ikora PCB, cyangwa, niba ufite ibikoresho nkenerwa, urashobora gutekereza gukora PCB murugo. Menya neza ko uburyo bwatoranijwe bwo gukora bwujuje ibisabwa byihuta, nkibikorwa bigenzurwa ninganda zikora ibikoresho byujuje ubuziranenge.

Guteranya prototype:

Umaze kwakira prototype yuzuye ya PCB, urashobora guteranya ibice. Witonze ugurisha buri kintu kuri PCB, witondera byumwihariko ibimenyetso byihuta byihuta. Koresha uburyo bukwiye bwo kugurisha kandi urebe neza ko ingingo zawe zigurisha zifite isuku kandi zizewe. Gukurikiza inganda nibikorwa byiza bizafasha kwirinda ibibazo bishobora kuba ibiraro byabacuruzi cyangwa imiyoboro ifunguye.

Gerageza no kwemeza prototypes:

Iyo prototype ya PCB imaze guterana, igomba kugeragezwa neza no kugenzurwa. Koresha ibikoresho byipimisha bikwiye, nka oscilloscope cyangwa isesengura ryurusobe, kugirango umenye imikorere yitumanaho ryamakuru. Gerageza ibintu bitandukanye, harimo igipimo cyamakuru atandukanye, imizigo itandukanye hamwe n urusaku rworoshye, kugirango PCB yujuje ibisabwa. Andika ibibazo cyangwa imbogamizi zabonetse mugihe cyo kwipimisha kugirango irusheho kunozwa nibikenewe.

Iterate kandi unonosore igishushanyo:

Prototyping ni inzira itera, kandi imbogamizi cyangwa ahantu hagomba kunozwa akenshi bizahura mugihe cyibizamini. Gisesengura ibisubizo byikizamini, kumenya aho ugomba kunozwa, no gushyira mubikorwa impinduka. Wibuke gutekereza kubimenyetso byerekana ibimenyetso, guhagarika EMI, no gukora ibishoboka mugihe uhindura. Subiramo igishushanyo nicyiciro cyibizamini nkuko bikenewe kugeza igihe ibyifuzo byihuta byitumanaho byitumanaho bigerwaho.

Mu gusoza:

Gukoresha PCB hamwe namakuru yihuta yamakuru yamakuru bisaba gutegura neza, kwitondera amakuru arambuye, no kubahiriza imikorere myiza. Mugusobanukirwa ibisabwa, guhitamo ibice bikwiye, gushushanya uburyo bwiza, kwigana no gusesengura igishushanyo, gukora PCB, kuyiteranya neza, no kugerageza neza no gusubiramo kuri prototypes, urashobora guteza imbere PCBs ikora cyane kugirango ikore neza. Itumanaho ryihuse ryamakuru. Komeza kunonosora ibishushanyo kandi ukomeze kuvugururwa hamwe nubuhanga bugezweho hamwe nubuziranenge kugirango ukomeze imbere yumurongo muri uyu murima uhora utera imbere.
