Iyo yakajairwa PCB Dhizaina ikozvino haina kupfuura 10A, kunyanya mumhuri uye vatengi magetsi, kazhinji vachishanda vachishanda zvazvino paPCB haina kupfuura 2a.

Nekudaro, zvimwe zvigadzirwa zvakagadzirirwa kushandisa simba, uye zviripo zvino zvinogona kusvika anenge 80a. Kufunga nezvekunyatsosiya mari uye kusiya margin yehurongwa hwese, iko kuenderera mberi kwemusha wive wiring kunofanirwa kukwanisa kutsungirira kupfuura 100a.

Ipapo mubvunzo ndewekuti, ndeupi mhando yePCB inogona kumira iripo yeiyo 100a?

Nzira 1: Kugadziriswa kwePCB

Kuti ufunge nezve -zvino kugona kwePCB, isu tinotanga kutanga nePCB chimiro. Tora kaviri-layer PCB semuenzaniso. Iyi mhando yedunhu redunhu inowanzove ine matatu-layer chimiro: chivharo ganda, ndiro, uye gomba remhangura. Iyo yeganda remhangura ndiyo nzira iyo iyo iripo uye chiratidzo muPCB Pass.

Zvinoenderana neruzivo rwechikoro chepakati pofidsics, tinogona kuziva kuti kuramba kwechinhu chine chekuita nezvinhu, nzvimbo yekuyambuka, uye kureba. Kubva patiri zvazvino kumhanya paganda remhangura, kuramba kwakasimba. Nzvimbo yemuchinjiko-chikamu-chikamu chinogona kutorwa sekukora kweganda remhangura, rinova mhirizhonga yemhangura muPCB yekugadzirisa PCB.

Kazhinji kopper brickness inoratidzwa mu oz, the they ripper pane 1 oz ndeye 35 um, 2 oz in 70 um, zvichingodaro. Ipapo inogona kupedzisira nyore nyore kuti kana yakakura iripo pati yePCB, iyo wiring inofanirwa kunge ipfupi uye yakakura, uye iyo mhangura yePCB, zviri nani.

Chaizvoizvo, mune engineering, hapana chimiro chakasimba chekureba kwe wiring. Kazhinji inoshandiswa muinjiniya: mhangura tsicess / tembiricha yemhembwe / tembiricha yekushisa / waya diameter, izvi zvitatu zviratidzo kuyera kutakura kwazvino kwePCB Bhodhi.
