Popanga PCB, takhumudwitsidwa kuti tilize PCB ngati tabo -njira kuti tithane ndi ma board athu.
Kodi kusaka ma tabo ndi chiyani?
Tab routing ndi njira yodziwika bwino ya PCB yomwe imagwiritsa ntchito ma tabo okhala ndi kapena opanda perforations.Ngati mukulekanitsa PCBs panelized pamanja, muyenera kugwiritsa ntchito mtundu perforated.Ngati mukuwona kuti kuswa PCB kuchokera pagulu kungayambitse kupsinjika kwambiri pa PCB, ndikwanzeru kugwiritsa ntchito chida chapadera chomwe chingalepheretse kuwonongeka kwa bolodi.
Ngati bolodi ili ndi mawonekedwe osakhazikika, kapena bolodi ikufunika m'mphepete bwino ndiye kuti gululo liyenera kuyendetsedwa.Chithunzi 8 chikuwonetsa chojambulira cha tabu -njira yolowera, Chithunzi 9 ndi chithunzi cha gulu lowongolera tabu.Mu tabu-routing gulu kuti athyole bolodi pa gulu pambuyo msonkhano, V mphambu kapena "mbewa kuluma mabowo" angagwiritsidwe ntchito.Mabowo a mbewa ndi mzere wa mabowo omwe amagwira ntchito mofanana ndi mabowo pa masitampu.Koma kumbukirani kuti V mphambu ipereka m'mphepete momveka bwino pambuyo poti matabwa achoka pamagulu, "mabowo oluma mbewa" sangamveke bwino.
Chifukwa chiyani tifunika kupanga ma board ngati tad-routing?
Ubwino umodzi wowongolera ma tabo ndikuti mutha kupanga matabwa omwe si amakona anayi.Mosiyana ndi izi, choyipa chowongolera ma tabo ndikuti pamafunika zida zowonjezera, zomwe zitha kukulitsa mtengo wanu.Itha kuyikanso kupsinjika kwambiri pa bolodi pafupi ndi tabu.Kuti mupewe kupsinjika, pewani kuyika magawo a PCB pafupi ndi ma tabo.Ngakhale kulibe mulingo wachindunji woyika magawo pafupi ndi ma tabo, nthawi zambiri, 100 mils ndi mtunda wamba.Kuphatikiza apo, mungafunike kuyika magawo opitilira 100 mils kwa PCB zazikulu kapena zokulirapo.
Mutha kuchotsa ma PCB mu mapanelo asanasonkhanitsidwe kapena atatha.Popeza mapanelo PCB kukhala kosavuta kusonkhana, njira ambiri ndi kuchotsa PCBs pambuyo gulu anasonkhana.Komabe, muyenera kugwiritsa ntchito chisamaliro chowonjezera pochotsa ma PCB ku mapanelo atasonkhanitsidwa.
Ngati mulibe wapadera PCB kuchotsa chida, muyenera kusamala pamene kuchotsa PCBS gulu.Osapindika!
Ngati mutasiya PCB kuchokera pagulu popanda kusamala, kapena ngakhale zigawozo zili pafupi kwambiri ndi ma tabo, mukhoza kuwonongeka.Kuphatikiza apo, olowa solder nthawi zina amaphulika, zomwe zingayambitse mavuto pambuyo pake.Ndibwino kugwiritsa ntchito chida chodulira kuti muchotse ma PCB kuti mupewe kupindika bolodi.
PHILIFAST wakhala odzipereka mu PCB kupanga kwa zaka zambiri, ndi kuthana ndi PCB m'mphepete bwino kwambiri.Ngati pali vuto lililonse mumapulojekiti anu a PCB, ingopitani kwa akatswiri mu PHILIFAST, adzakupatsani malingaliro aukadaulo.
