A PCB (Printed Circuit Board) ndiyo hwaro hwemidziyo yemagetsi, inobvumira kubatana uye kuyerera kwemagetsi pakati pezvikamu zvakasiyana.Kunyangwe iwe uri wezvemagetsi hobbyist kana nyanzvi, kuziva kugadzira PCB maseketi hunyanzvi hwakakosha hunogona kusimudzira mapurojekiti ako etekinoroji.Mune ino blog, isu tinopa nhanho nhanho gwara rekuita PCB dunhu.
1. Dhizaini uye hurongwa hwekugadzira:
Nhanho yekutanga mukugadzira PCB dunhu kugadzira nekugadzira schematic.Uchishandisa dhizaini dhizaini software, senge Eagle kana KiCad, dhirowa dhizaini redunhu.Nekungwarira kuiswa kwezvikamu, iyo yakakwana dhizaini inova nechokwadi chekuyerera kwemasaini uye nzira inoshanda yakakosha.
2. PCB marongerwo:
Kana iyo schematic yapera, nhanho inotevera ndeyekugadzira iyo PCB marongero.Iyi nzira inosanganisira kuendesa zvikamu uye zvinongedzo kubva kune schematic kuenda kune yemuviri bhodhi dhizaini.Rongedza zvikamu nemapakeji azvo, kuve nechokwadi chekutarisa kwakaringana uye kuchengetedza nzvimbo yakakwana kudzivirira kukanganisa.
3. Kuiswa kwendiro:
Kana iyo PCB dhizaini yapera, inguva yekuisa bhodhi.Kutanga dhinda dhizaini yedhizaini pane yakakosha bepa rekufambisa uchishandisa laser printer.Isa iyo yakadhindwa paPCB yemhangura uye inopisa nesimbi kana laminator.Kupisa kunotamisa inki kubva papepa kuenda kubhodhi, kuumba chidziviriro chekudzivirira pamatanho emhangura.
4. Etching process:
Kana kuendesa kwapera, inguva yekuisa bhodhi.Gadzirira chigadziko chine yakakodzera etching solution (yakadai seferric chloride) uye nyura bhodhi mariri.Gadzirisa zvinyoro mhinduro kuti ubvise mhangura yakawandisa kubva munzvimbo dzisina kudzivirirwa, uchisiya chete maitiro anodiwa.Munguva iyi, ita shuwa kutora matanho ekuchengetedza sekupfeka magurovhosi uye magirazi, sezvo etching mhinduro inogona kuve nengozi.
5. Kuchera:
Mushure mekucheka, maburi anoda kudhirwa kuti aise zvikamu.Shandisa chibooreso chine chidimbu chinofanana nekukura kwechikamu chinotungamira.Nyatsoboora nepakati pezvikamu zvakatarwa uye ona kuti maburi akachena uye haana chero tsvina.
6. Welding:
Mushure mekunge bhodhi rave rakatemwa uye maburi akaboorwa, inguva yekutengesa zvinhu paPCB.Tanga nekupinza zvinhu kuburikidza nemakomba azvo, uchiita shuwa kuti akagara akachengeteka.Flip bhodhi pamusoro uye solder chimwe nechimwe chikamu, kushandisa kupisa kunyungudutsa solder waya uye kugadzira chisungo chakasimba.Shandisa simbi yemhando yepamusoro uye flux kuti uwane yakachena, yakavimbika solder majoini.
7. Muedzo:
Mushure mekutengesa zvikamu zvose, kushanda kwedunhu kunofanira kuongororwa.Shandisa multimeter kuti utarise kuenderera mberi uye kuona kwakakodzera kubatana.Zvakare, ita ongororo yekuona kuti hapana mabhiriji ekutengesa kana majoini anotonhora.
mukupedzisa:
Kugadzira maseketi ePCB kungaite sekunetsa pakutanga, asi neruzivo rwakakwana uye maturusi, rinogona kuve basa rinogoneka.Nekutevera nhanho-ne-nhanho gwara rakapihwa mune ino blog, unogona nechivimbo kugadzira PCB maseketi emapurojekiti ako emagetsi.Rangarira, kudzidzira kunoita kuti kuve kwakakwana, saka usaore moyo kana zvichitora mashoma kuyedza kuwana kurembera kwemaitiro.Nenguva uye ruzivo, iwe unozokwanisa kugadzira zvakaomarara uye nepamusoro-kuita PCB maseketi.
