Ko PCB yakakwana kana marongerwo apera uye hapana matambudziko anowanikwa nekubatanidzauye spacing?
Mhinduro, hongu, kwete. Vazhinji vanotanga, kunyangwe kusanganisira vamwe mainjiniya vane ruzivo, nekuda kwenguva shoma kana kusashivirira kana kuzvivimba zvakanyanya,
vanowanzo kurumidza, vasingatarise kunonoka kutarisa, kwave kune mamwe akadzika-pamwero tsikidzi, senge mutsara wakafara hauna kukwana, components label printing.
dzvinyiriro uye maburi ekubuda aive ari padhuze, masaini muchiuno, zvichingodaro, zvinotungamira kumatambudziko emagetsi kana maitiro, zvakakomba kutamba bhodhi, kutambisa. Naizvozvo,
post-kuongorora inhanho yakakosha mushure mekunge PCB yaiswa.
1. Component packaging
(1) Pad spacing. Kana chiri chishandiso chitsva, kudhirowa yavo yezvikamu pasuru, ona kuti nzvimbo yacho yakakodzera. Pad spacing inokanganisa zvakananga kune welding yezvikamu.
(2) Via size (kana iripo). Kune plug-in zvishandiso, saizi yegomba inofanirwa kuchengetwa yakakwana margin, kazhinji isiri pasi pe 0.2mm inonyanya kukodzera.
(3) Mhedziso yesiriki skrini. Iyo contour screen kudhinda kwezvikamu kunofanirwa kuve
yakakura kupfuura saizi chaiyo kuti ive nechokwadi chekuti mudziyo unogona kuiswa zvakanaka.
2. Kurongeka
(1) IC haifanire kunge iri padyo nemupendero webhodhi.
(2) Izvo zvikamu zvedunhu mune imwechete module zvinofanirwa kuiswa padyo nemumwe. Somuenzaniso, decoupling capacitor inofanira kuva
padyo nepini yekupa magetsi yeIC, uye zvikamu zvinoumba dunhu rimwe chete rinoshanda zvinofanirwa kuiswa munzvimbo imwechete nehumambo hwakajeka.
kuve nechokwadi chekuzadzikiswa kwemabasa.
(3) Rongedza socket nzvimbo maererano nekuiswa chaiko. Socket yakabatana kune mamwe ma module kuburikidza nekutungamira, zvinoenderana nechimiro chaicho,
kuti uise zviri nyore, kazhinji shandisa iri pedyo misimboti kuronga socket chinzvimbo, uye kazhinji padyo nebhodhi kumucheto.
(4) Teerera kune nzira yekubuda nayo. Socket inoda gwara, kana gwara rakapesana, waya inoda kuitwa. Kune socket yakatsetseka, kutaridzika kwesoketi kunofanirwa kunge kuri kunze kwebhodhi.
(5) Panofanira kunge pasina michina munzvimbo yekuchengetera kunze.
(6) Iko kupindira kunofanira kunge kuri kure nedunhu rinonzwa. Chiratidzo chekumhanya kwepamusoro, wachi yekumhanya yakakwira kana yakakwira ikozvino chinja siginecha zvinhu zvekuvhiringidza, zvinofanirwa kunge zviri kure nedunhu rinonzwa (senge reset reti, analogi wedunhu). Vanogona kuparadzaniswa nepasi.
