Tikugashirei zvakare, vanoda tekinoroji uye DIY vanofarira! Nhasi, tarisiro yedu iri pamabhodhi ePCB, kureva, mabhodhi edunhu akadhindwa. Izvi zvidimbu zvidiki asi zvakakosha zviri pamwoyo pezvizhinji zvemagetsi uye zvine basa rekuona basa razvo chairo. Kunyangwe iwe uri nyanzvi yeinjiniya kana hobbyist, kuziva maitiro ekuongorora PCB board kwakakosha pakugadzirisa nekuchengetedza midziyo yemagetsi. Saka, ngatinyure mumatanho anodiwa kuyedza uye kuona kuvimbika kwePCB board!
1. Kuongorora kwekuona:
Nhanho yekutanga yekuongorora PCB ndeyekunyatsoongorora yekuona. Tarisa bhodhi redunhu pane chero kukuvara kwemuviri, senge ngura, yakatsva zvinhu, kana kusununguka. Tarisa zviratidzo zvekuputsika kana kukuvadzwa, zvikamu zvisina kurongeka, kana zviratidzo zvekupisa. Kuongorora kwekuona kungaita sekwakareruka, asi kunogona kubatsira kunyatsoona matambudziko anogona kuitika.
2. Kuongororwa kwechikamu:
Mushure mekutarisa kwekuona, enderera mberi nekuongorora chimwe nechimwe chikamu paPCB board. Tanga nekuita shuwa kuti zvese zvikamu zvakaiswa, zvakarongeka, uye zvakatengeswa nemazvo. Shandisa multimeter kuyera kuramba uye kuenderera kwema capacitors, resistors, uye zvimwe zvinhu zvemagetsi. Chengetedza zvakanyanya kune zvikamu izvo zvinogona kutadza kutadza, senge capacitors ane akabudikira kumusoro kana kupiswa kunze resistors.
3. Simba pabvunzo:
Kamwe kuongorora kwekuona uye kuongorora kwechikamu kwapera, inguva yekuita bvunzo-yesimba. Batanidza PCB board kune yakavimbika magetsi sosi zvinoenderana nemugadziri wacho. Tarisa bhodhi rako raamai kuitira hunhu husina kujairika, sekupisa, kuputa, kana kudzima kamwe kamwe. Ndokumbira uchenjere kuti usabata chero zvikamu apo bhodhi rinenge richibatidzwa, sezvo yakakwirira voltages inogona kuunza njodzi yekuvhundutsa.
4. Signal test:
Pamusoro pesimba-pakuyedza, masaini anotumirwa uye anogamuchirwa nePCB board anofanirwawo kutariswa. Shandisa oscilloscope kutarisa masaini ekubuda uye mazinga evoltage uye uzvienzanise nezvinodiwa. Wona kuti chiratidzo chakagadzikana pasina kukanganisa kana kuchinja. Iyi nhanho yakakosha, kunyanya mumabhodhi ePCB akaomarara uko akawanda mazvikamu anopindirana.
5. Kuedza kunoshanda:
Kuti uve nechokwadi chekuita kwakakwana kwePCB board, zvakakosha kuita bvunzo inoshanda. Batanidza bhodhi kune mudziyo wakakodzera wainoshanda nawo, senge mota kana sensor. Tarisa kuti bhodhi rePCB rinoita basa rayo rakatarisirwa nemazvo. Wona kuti hukama hwekupinza-zvekubuda hwakarurama uye kuti mashandiro ese anoshanda sekutarisira. Iyi nhanho inogona kuda zvimwe zvemhando yepamusoro senge logic analyzer kana basa jenareta, zvichienderana nekuoma kwePCB board.
Makorokoto! Nekutevera matanho ari pamusoro apa, wadzidza nzira yekunyatso tarisa kushanda uye kuita kwePCB board yako. Rangarira, kuyedzwa chaiko kwakakosha kuti uve nechokwadi chekuti michina yako yemagetsi inoshanda zvakanaka uye nekuvimbika. Kana paine chero nyaya dzikamuka panguva yekuyedzwa, kunzwisisa iyo mudzi chikonzero ndiyo nhanho yekutanga kugadzirisa dambudziko. Muchiitiko chekukuvadzwa kwakanyanya kana nyaya dzakaoma, tsvaga rubatsiro kubva kune nyanzvi dzePCB kana nyanzvi dzekugadzirisa zvemagetsi nekukurumidza. Gara uchida kuziva, ramba uchidzidza, uye unakirwe nemiedzo yePCB board!
