Kwiintsuku ezimbalwa ezidlulileyo besithetha nawe malunga Ungazithenga phi izinto ze-Intanethi ezikwi-Intanethi?, kwaye uninzi lwenu lusithumelele izimvo ngokubhekisele kwiisekethi eziprintiweyo (i-PCB), njengoko uninzi luvumile ukuba ixabiso laleisekethe liphezulu ukuba zithengwa eMelika okanye eSpain, kodwa kwamanye amazwe ixabiso liphantsi. Ndizithengele ngokwam Ii-PCB ezili-10 zixabisa i- $ 2 en ijcbb.com, umgangatho kunye nexesha lokuhambisa lalilungile kakhulu, kwaye isixhobo salo sombukeli wegerber sivumela uyilo ukuba lube lolugqibeleleyo.
Zithini iisekethe eziprintiweyo (PCB)?
Las iibhodi zesekethe eziprintiweyo eyaziwa ngesiNgesi njenge I-PCB (iBhodi yeSekethe eprintiweyo)Ayisiyonto ingaphezulu kobuso obuqulathe ubume beekhondreji ezilaminethiweyo ezivumela izinto ezahlukeneyo zombane ukuba zidityaniswe ngombane, ngendlela efanayo, sisiseko sokulungisa esingasebenziyo apho izinto zesekethe zihlala khona.
Eziisekethi ziprintiweyo zinokwenziwa ngesandla, kodwa iindleko zazo ziphezulu, yiyo loo nto ifayile ye- Ukudalwa kwe-PCB ngendlela ezenzekelayo, apho ukunyuka kwamajelo aqhubayo kunyukile, ukongeza, iindleko zokuprinta kunye nezendibano ziyehliswa.
Ii-PCB zifakelwe kwizixhobo zombane ezininzi kwaye sisizathu sokuzenzela izinto ezininzi, izixhobo kunye ne-automata.
Yintoni iJLCPCB?
IJLCPB (I-Shenzhen JIALICHUANG yoPhuculo lweTekhnoloji yoPhuculo lweComputer, Ltd.), yiyo inkampani eyenza i-PCB ngamaxabiso asezantsi kakhulu, ezikumgangatho ophezulu kwaye ngexesha elifutshane ngokufanelekileyo, ngokwewebhusayithi yazo zi-lAbavelisi PCB inkulu China, ukuba ngaphezulu kwe 200.000 abathengi kwihlabathi liphela nangaphezulu 8000 odola ngosuku.
Ngokwamava am I-JLCPB ngumenzi othengisa inkonzo yokuprinta ye-PCB, ngendlela elula, ekhawulezayo, netekhnoloji ephezulu, enexabiso elifikelelekayo kakhulu leedola ezi-2 ngeziqwenga ezili-10 kwaye, ngaphezu kwako konke, ukuba ukuthunyelwa kwayo kukhuselekile, kuthathelwa ingqalelo ukuba kwimeko yam ukwenziwa kwayo kuhlala ixesha elincinci kakhulu.
Kukho inani elikhulu leendlela ezizezinye kwiJLCPB ezinje nge-pcbway, 4pcb, pcbcarte phakathi kwezinye, kodwa ngokobuqu andinakho ukugxekwa ne-JLCPB kwaye ukuthelekisa amaxabiso zezona zinike esona sipho silungileyo.
Ungazithenga njani iisekethi eziprintiweyo nge- $ 2?
Kwilabhoratri ye-elektroniki endiyimiselayo ndifuna ukwenza umfanekiso we I-ARDUINO MOTOR SHIELD REV3Ke bendineeseti zePCBs ezenziwe ngeJLCPB ezinokundivumela ukuba ndihlanganise zonke izinto eziyimfuneko.
Emva koko ndishiya ifayile ye- I-ARDUINO MOTOR SHIELD REV3 ifayile yeGerber ukuba ufuna ukuyisebenzisa kuvavanyo oluthile.
Inkqubo yoku-odola kunye nokuthenga i-10 pcb ye IArduino Motor Shield REV3 yayile ilandelayo:
- Sivula indawo ye IJLCPCB, Siboniswa ikhalityhuleyitha yebhajethi esisa kwiphepha loku-odola. Kwikhaltyhuleyitha yokucaphula, ngenisa nje ubungakanani bePCB, ubungakanani, umaleko kunye nobukhulu.
- Emva koko sicofa CAPHA NGOKU / QAPHELA NGOKU, oku kuya kukusa kwiphepha lesicatshulwa apho ufaka khona zonke iinkcukacha ezifunekayo.
Andiyongcali ngokukodwa kwiisekethe zombane ke ndaye ndagqiba kwelokuba ndishiye ubumbeko olungagqibekanga, kodwa ungenza uhlengahlengiso oluyimfuneko ukuze i-PCB ifane nendlela oyifunayo, ngendlela efanayo, ukhetho ngalunye lunophononongo oluluncedo, ukuze luncedo kakhulu xa usenza isigqibo ngento enye.
- Emva koko cofa apha Gcina kwinqwelo / cofa ugcine kwinqwelo kwaye oko kuya kukuthatha kwiphepha eliza kukucela ukuba ungeze iifayile zakho zeGerber (ungasebenzisa le ndiyishiye ngaphambili), kananjalo nentlawulo eyongezelelweyo banokubeka phambili ixesha lokuvelisa le-PCB.
- Ungalibali layisha ifayile yakho yeGerber . Emva kokulayisha i-gerber, ngokulula yenza cofa SINDAWO YOKUQHUBA / GCINISA INQWELO
- Okokugqibela, yenza intlawulo ehambelana nomyalelo wakho kunye nexesha lokuhlawula elikufanela kakuhle, iodolo yakho iya kwenziwa kwaye inqanaba leodolo yakho iya kuboniswa, emva kokwenza kunye nokuthumela uya kunikwa ikhowudi yokulandela.
Ndonelisekile ngamaxesha okuhanjiswa kweePCB zam kunye nomgangatho ofanayo, kwimveliso enkulu ngokuqinisekileyo amaxabiso kufuneka ehle, kodwa ekusebenziseni endikunike i2 $ ibingaphezulu kokulungileyo utyalo-mali.
Ndiyathemba ukuba olu lwazi luluncedo kwabo basebenzisi banomdla kwiisekethi zombane nakwiilebhu zelektroniki.
Molo unjani? Ndihlala ndindwendwela iphepha lakho kodwa kunqabile ukuba ndiphawule (bambalwa kakhulu).
Ndifuna ukukubuza into, ndinomthombo weSentey otshise i-1 polarised electrolytic capacitor ye-560uF 200V kodwa kubonakala ngathi akukho mntu unayo, okanye bandinika i-470 okanye i-660uf kunye ne-250 okanye i-300V. Ngaba uyazi naliphi na iphepha elibathengisayo? ixabiso alisenamsebenzi.

Sawubona Ongaziwayo, i-470uf electrolytic capacitors imiselwe emgangathweni, unokuzifumana nakweyiphi na indlu ye-elektroniki, ezi-660uf aziqhelekanga kangako nakweyiphi na imeko kubalulekile ukuba i-voltage ibe ngama-200V phezulu, kodwa ukuba une-capacitor okanye i-capacheck okanye Umhlobo onokuthi ujonge nayiphi na iplate ye-tv endala okanye umthombo we-pc oya kuthi ngokuqinisekileyo ufumane okuthile.
Kwintengiso yasimahla ungakhangela i-inshurensi uyakufumana kodwa andazi ukuba bazokuthengisa nge-1 kuphela Mhlobo mhlobo
Ngokubhekisele kumacwecwe ndiyaqhubeka nendlela yakudala yokwenza ngokukhululekileyo kunye nommakishi omdala nothandwayo,
Ukurekhoda, ziipleyiti ezilula ezisisiseko.
I-PS: Kubantu be-BS AS eBuogne Sur Mer uza kufumana izindlu ezininzi ze-elektroniki ukuba uhlala kufutshane, imibuliso.
Molo ebusuku, ndinibhalela ndisuka eColombia. Umbuzo wam ngulo, emva kokugqiba yonke le nkqubo, ndibone ukuba bakunika uhlobo lwe-invoice, okanye njengoko besitsho ngesiNgesi "invoice" apho bakunike lonke ulwazi lokuhambisa, ndingathanda ukwazi ukuba leliphi inani lesikhokelo ithunyelwe kwaye ulandela phi ukuthunyelwa (iphepha lewebhu), ndiza kwenza ukuthengwa kweePCBs kodwa ezo datha azicacanga kum kwiphepha. Imibuliso emininzi kwaye ndiyalithanda iphepha lakho.
Kwiqonga xa i-pcb yenziwe kwaye ithunyelwe, iodolo yakho ihlaziywa ngenombolo yokulandela umkhondo yeodolo yakho.
Ndisebenzisa iiPCBs https://oshpark.com/ Kuba, kuxhomekeke kukhetho, abakuhlawulisi ngokuthumela. Iphepha labo linobuhlobo, liyakwamkela iifayile kwi-kicad.
Ixabiso lokugqibela liphindaphindwe ngo-6 xa kusongezwa iindleko zokuhambisa, ubuncinci eSpain zii- $ 2 + $ 10.98: /
Yiyo loo nto iTshayina ilawula.
