Mohato oa 1: Qala ka ho sebelisa Altium Designer ho rala setšoantšo sa schematic le PCB ea potoloho
Mohato oa 2: Hatisa setšoantšo sa PCB
Pampiri e hatisitsoeng ea ho fetisa mocheso ha e ntle haholo hobane cartridge ea enke ea mochine oa khatiso ha e ntle haholo, empa ha ho tsotellehe, e ka etsoa bakeng sa phetiso e latelang.
Mohato oa 3: Seha pampiri e fetisang ea mocheso e hatisitsoeng
Mohato oa 4: Fetisetsa PCB potoloho
CCL ebe u khaola pampiri ea ho fetisa mocheso
Khaola laminate ea koporo ho ea ka boholo ba boto ea PCB
Ha e le hantle, laminate e entsoeng ka koporo e lokela ho belisoa ka sandpaper e ntle pele e fetisoa (ho bentša lesela la oxide)
Theipi ka lehlakoreng le leng la pampiri ea ho fetisa
Setsi sa phetisetso ea nalane (PS: Ka lebaka la Taobao ea matla 'ohle, ke uena feela eo u ke keng ua e nahana, empa ha u e fumane)
Kamora ho fetisoa ha 4, ho lokile, e tlohele e pholile ebe e e arola
E ka atleha joang?
Ehlile, haeba ha u na mochini o fetisang mocheso, u ka sebelisa tšepe (*^__^*) Hee hee…
Mohato5: Tlatsa le fetisetsa PCB boto
Kaha cartridge ea khatiso ha e ntle haholo, u ka sebelisa letšoao ho tlatsa sebaka se sa fetisetsoang hantle.
O(∩_∩)O~ Ha ho mpe!
Mohato oa 6: Boto ea Corrosion PCB
Se mpotse!E-ea ka ho toba Taobao
Corrosion artifact (molamu o futhumatsang + aerator ea tanka ea tlhapi + lebokose la polasetiki = mochini oa corrosion oa PCB)
Ke bone motho e mong ka lab a tjheseletsa li-cubes tse 8X8X8 tse bobebe ha a ntse a emetse hore kutu e fele
Seo ba se qapileng ka bobona se ile sa romela boto ho se etsa
Corrosion e felile
Mohato oa 7: Ho phunya le ho Tinning
Sebelisa sandpaper e ntle ho lehlabathe toner holim'a boto ea PCB ka metsing
Sebelisa k'hothone swab ho sebelisa lesela la rosin holim'a PCB (eng? U mpotsa hore na rosin ke eng? Rosin ke ho qhaqha rosin ka 70% joala)
Molemo oa ho sebelisa rosin ke hore e sebelisoa e le ho phalla ha soldering.Molemo o mong ke hore o na le phello ea anti-oxidation.
tinngoe
qetellong ea tinned
Tebeletsa
Mohato oa 8: Welding le debugging
Kamora ho lokisa bothata, ke ile ka fumana hore ho fihlela mosebetsi oo ke o batlang, ho na le tlhahiso e le 'ngoe e ka tlase ho ea ho hula-up resistor O(∩_∩)O~
sehlahisoa se felileng
(PS: Leseli la ho lemoha la ts'ebetso e sebelisoang ke potoloho ena le tla khantša LED ka boto ha leseli le fihla matla a itseng)
