Prototyping ibhodi - yini lokho?!

Ibhodi ukuthuthukiswa kuyinto nezimo ephrintiwe wesifunda ibhodi, okusho ebusweni, eziklanyelwe lokukhuphula ezihlukahlukene ze-elekthroniki. It has amakhulukhulu izimbobo ukuthi esebenzisa yensimbi kukhona kagesi sixhumene. Iziphetho chips kanye nezinto zikagesi afakwa izimbobo ezincane obujwayelekile bese zixhunywe izingcezu izintambo elingenalutho. Kulolu chungechunge othintana ibekwe phezulu, phansi futhi phakathi ebhodini, eziklanyelwe ndawonye amaphuzu amaningi wesifunda phansi ugesi. Kufanele kugcizelelwe ukuthi ibhodi ukuthuthukiswa akudingi nokunamathisela ngomthofu, ecucuza futhi solder. Ngaphezu kwalokho, lapho esebenza ke akukho ingozi izingxenye okweqile, kanye azikho izinkinga ezithile zokumpontshelwa izikimu obandayo amaningi.

Nazi izinhlobo amabhodi ukuthuthukiswa

Manje ochwepheshe izinhlobo ezintathu oyinhloko amabhodi ukuthuthukiswa. Okokuqala, kungenxa onobuhle jikelele, okuyinto zitholakala phezu kuphela -VIAS metallized. Bona kamuva unjiniyela kuyodingeka ixhunywe usebenzisa Jumpers. Eyesibili uhlobo - ibhodi ezikhethekile. Kulezi evele kukhona kokubili wesifunda okujwayelekile (pre-lwenkomo olufakwe amanzi), kanye izindlela futhi izimbobo yezifiso izifunda. Ekugcineni, uhlobo lwesithathu libhekisela prototyping amabhodi eyenzelwe amadivayisi obuchwepheshe. Kulokhu, lonke kobuso ophethe amandla ibhasi, bese kugandelelwe isikhala kulinganiselwa for chips.

Prototyping ibhodi, enziwe ngezandla zakhe

Yenza ikhadi okuzenzela, uma kunesidingo, kube ulula futhi amandla noma yimuphi umuntu. I ezazisetshenziselwa ukwenza isisekelo salo kangcono nefolgirovanny PCB. Line breadboard ngaleyo ndlela kungenziwa kusetshenziswa ngumbusi usungulo abukhali. Ngokuqondene izimbobo, zingenziwa ngu sokuprakthiza ka 0.8. Sami babashayeli zingenziwa zethusi wire, kanye ezidingekayo izingxenye umsakazo asethwe usebenzisa solder. Kulokhu bonke amalunga sehlisiwe ohlangothini engezansi futhi kusukela phezulu. Ngaphezu kwalokho, kubalulekile ukuthi okutholakele izingxenye umsakazo ibheke ngendlela yokuthi bagijima parallel umqhubi contact. Ngesisekelo ibhodi prototyping ulungile!

Izinkinga zokuthuthukiswa amabhodi isicelo

Onjiniyela ngubani esenziwa nemisebenzi yabo njalo usebenzisa prototypes amadivayisi ahlukahlukene electronic, uqaphele ukuthi ukusebenzisa kwawo i lihlotshaniswa, njengoba umthetho, izinkinga eziningi. Eyokuqala iyona ezisobala kakhulu futhi itholakala lokuthi ukuthi iyiphi ebhodini ukuthuthukiswa soldered ngesandla. Futhi endabeni phambili amaphutha enziwa esikhathini isikimu kubalulekile solder. Okwesibili, kumelwe kushiwo ukuthi ukwenza ngokuvamile onyathelisiwe wesifunda ibhodi akuyona inzuzo ukudala i-prototype eyodwa idivayisi electronic. Okwesithathu, uma wesifunda e-HTML analog degree eliphansi ukuhlanganiswa ovunyelwe ukwenza kwamanzi ngendlela obandayo, imishini sekhompiyutha ezisekelwe ukwenza kanjalo kunzima kakhulu. Ikhumbula ngokuhlela zonke lezi zici, kubalulekile ngaphambili ukuhlaziya konke ngaphambi kokuqala ukusebenza leli thuluzi, njengoba ibhodi prototyping.
