PCB Kulumikizana ndi cholumikizira chofunikira pakupanga kwa PCB. Anzanu ena sakudziwa kuchuluka kwa zingwe za PCB zomwe zimayikidwa. Apa timadziwitsa kuchuluka kwa zingwe za PCB zomwe zimayikidwa.

General PCB wiring line m’lifupi kuti muganizire zinthu ziwiri. Chimodzi ndikukula kwamakono, ngati pakadali pano pamawu akulu, mzerewo sungakhale wowonda kwambiri; Chachiwiri ndikulingalira zakapangidwe kake ka fakitole yama board ngati pano ndi yaying’ono, ndiye kuti mzerewo ukhoza kukhala wowonda pang’ono, koma wowonda kwambiri, fakitale ina ya PCB sangapangidwe, kapena kutulutsa koma zokolola zimatuluka, kotero tiyenera kuganizira vuto la fakitale yama board.

PCB kulumikizana mzere m’lifupi zambiri anapereka

Kutalika kwa mzere wonse kumayendetsedwa ku 6 / 6mil, ndipo kusankha kwa dzenje ndi 12mil (0.3mm), komwe kumatha kupangidwa ndi opanga ambiri a PCB pamtengo wotsika.

Mzere m’lifupi mzere mipata kulamulira osachepera 4 / 4mil, kudzera dzenje kusankha 8mil (0.2mm), oposa theka la opanga PCB zingabweretse, koma mtengo adzakhala pang’ono mtengo kuposa kutsogolo.

Kutalika kocheperako kumayang’aniridwa ku 3.5 / 3.5mil, ndipo kusankha kwa dzenje ndi 8mil (0.2mm). Opanga ma PCB ocheperako amatha kupanga PCB, ndipo mtengo wake ungakhale wokwera mtengo pang’ono.

Kutalika kochepa kwa mzere kumayendetsedwa ndi 2 / 2mil, ndipo kusankha kwa dzenje ndi 4mil (0.1mm). Ambiri opanga ma PCB sangathe kutulutsa, ndipo mtengo wamtunduwu ndiwokwera kwambiri.

Mzere m’lifupi akhoza kukhala malinga ndi kachulukidwe kapangidwe PCB. Ngati kuchulukako kuli kocheperako, kutalika kwa mzerewo ndi kutalikirana kwa mizere kumatha kukhala kokulirapo. Ngati makulidwewo ndi akulu, mzere wazitali ndi utali wa mzere ukhoza kukhazikitsidwa kukhala wocheperako:

1) 8 / 8mil, 12mil (0.3mm) ya perforation.

2) 6 / 6mil, 12mil (0.3mm) kudzera mu dzenje.

3) 4 / 4mil, 8mil (0.2mm) kudzera mu dzenje.

4) 3.5 / 3.5mil, 8mil (0.2mm) kudzera mu dzenje.

5) 3.5 / 3.5mil, 4mil kupyola dzenje (0.1mm, pobowola laser).

6) 2 / 2mil, 4mil kupyola dzenje (0.1mm, pobowola laser).
