Iyo yakajairika PCB dhizaini yazvino haipfuure 10A, kunyanya mudzimba uye mutengi zvemagetsi, kazhinji iyo inoenderera ichishanda ikozvino paPCB haipfuure 2A.

Nekudaro, zvimwe zvigadzirwa zvakagadzirirwa simba wiring, uye inoenderera ikozvino inogona kusvika ku80A.Tichifunga nezvezvino zvino uye nekusiya margin kune iyo yose system, iyo inoenderera mberi yemagetsi wiring inofanira kukwanisa kumira kupfuura 100A.

Zvino mubvunzo ndewekuti, rudzii rwePCB runogona kumira neiyo 100A?

Nzira 1: Kurongeka paPCB

Kuti uone kugona-kwazvino kwePCB, isu tinotanga nePCB chimiro.Tora kaviri-layer PCB semuenzaniso.Rudzi urwu rwebhodhi redunhu kazhinji rine matatu-layer chimiro: ganda remhangura, ndiro, uye ganda remhangura.Ganda remhangura ndiyo nzira iyo yazvino uye chiratidzo muPCB inopfuura.

Maererano neruzivo rwefizikisi yechikoro chepakati, tinogona kuziva kuti kupokana kwechinhu kune hukama nechinhu, chikamu-chikamu, uye kureba.Sezvo yedu ikozvino inomhanya paganda remhangura, iyo resistivity inogadziriswa.Iyo mhiri-chikamu nzvimbo inogona kutariswa sehukobvu hweganda remhangura, inova iko kukora kwemhangura muPCB yekugadzirisa sarudzo.

Kazhinji ukobvu hwemhangura hunoratidzwa muOZ, ukobvu hwemhangura hwe1 OZ i35 um, 2 OZ i70 um, zvichingodaro.Zvino zvinogona kugumiswa nyore nyore kuti kana yakakura ikozvino ichapfuudzwa paPCB, iyo wiring inofanira kunge ipfupi uye gobvu, uye iyo yakakura kukora kwemhangura yePCB, zviri nani.

Chaizvoizvo, muinjiniya, hapana chiyero chakasimba chehurefu hwewaya.Inowanzo shandiswa muinjiniya: ukobvu hwemhangura / tembiricha kusimuka / waya dhayamita, aya matatu maratidziro ekuyera ikozvino kutakura kugona kwePCB board.
