PCB wiring chikamu chakakomba kwazvo chePCB dhizaini. Dzimwe shamwari hadzizive kuti yakawanda sei pcb wiring mutsara upamhi inowanzoiswa. Ngatitaurirei kuti yakawanda sei pcb wiring mutsara upamhi inowanzo gadzirirwa.

Kazhinji, pane zvinhu zviviri zvekufunga nezvePCB wiring mutsara upamhi. Yokutanga ukuru hwazvino. Kana iyezvino kuyerera kuri kukuru, kuronda kwacho hakugone kuve kwakatetepa; yechipiri ndeyekutarisa iro chairo bhodhi kugadzira chinzvimbo chebhodhi fekitori. Kana iyo yazvino iri diki, trace inogona kuve yakatetepa, asi kana yakatetepa, Mamwe mafekitori ePCB bhodhi anogona kutadza kuaburitsa, kana iwo anogona kuaburitsa asi huwandu hwezvibereko hwakwira, saka bhodhi fekitori inofanirwa kutariswa .

Yakawanda sei iyo pcb wiring mutsara upamhi inowanzo gadzirirwa

Kazhinji, hupamhi hwemutsara uye nzvimbo yemitsara zvinodzorwa kusvika 6 / 6mil, uye iyo gomba iri 12mil (0.3mm). Vazhinji vagadziri vePCB vanogona kuiburitsa, uye mutengo wekugadzira wakaderera.

Iyo shoma mutsara upamhi uye mutsara spacing inodzorwa kusvika 4 / 4mil, uye iyo gomba iri 8mil (0.2mm). Inopfuura hafu yevagadziri vePCB vanogona kuigadzira, asi mutengo unenge uchidhura zvishoma pane yapfuura.

Iyo shoma mutsara upamhi uye mutsara spacing inodzorwa kusvika 3.5 / 3.5mil, uye iyo gomba iri 8mil (0.2mm). Kune vashoma pcb vagadziri vanogona kuburitsa, uye mutengo unenge uchidhura zvishoma.

Iyo shoma mutsara upamhi uye mutsara spacing inodzorwa kusvika 2 / 2mil, uye iyo gomba iri 4mil (0.1mm). Vazhinji pcb vagadziri havagone kuiburitsa. Iyi mhando yemutengo ndiyo yepamusoro.

Kana hupamhi hwemutsara hwakaiswa zvinoenderana nehukuru hwePBB dhizaini, iyo diki iri diki, uye hupamhi hwemutsara uye nzvimbo yemitsetse inogona kuiswa kuti ive hombe, uye kuwanda kunogona kuiswa kuti kuve kudiki:

1) 8 / 8mil, 12mil (0.3mm) yepakati mugomba.

2) 6 / 6mil, 12mil (0.3mm) yepakati mugomba.

3) 4 / 4mil, 8mil (0.2mm) yepakati mugomba.

4) 3.5 / 3.5mil, 8mil (0.2mm) yepakati mugomba.

5) 3.5 / 3.5mil, 4mil yeiyo kuburikidza negomba (0.1mm, laser kuchera).

6) 2 / 2mil, 4mil yeiyo kuburikidza negomba (0.1mm, laser kuchera).
