PCB wiring chinhu chakakosha chinongedzo muPCB dhizaini. Dzimwe shamwari hadzizive kuti yakawanda sei pcb wiring upamhi inowanzoiswa. Pano isu tinosuma mangani pcb wiring upamhi inowanzo setwa.

General PCB wiring mutsara upamhi kuti utarise nyaya mbiri. Imwe ihwo ukuru hwazvino, kana iyo yazvino kuburikidza nemazwi makuru, mutsetse haugone kutetepa zvakanyanya; Yechipiri ndeyekutarisa chaiyo ndiro inogadzira chinzvimbo chebhodhi fekitori kana yazvino iri diki, ipapo tambo inogona kuve yakatetepa, asi yakatetepa, imwe pcb board fekitori inogona kusaburitswa, kana kugadzirwa asi goho rinokwira, saka isu tinofanirwa kufunga nezve bhodhi fekitori dambudziko.

Pcb wiring mutsara upamhi inowanzo gadzirirwa

Iyo yakafara mutsetse upamhi inodzorwa kusvika 6 / 6mil, uye gomba kusarudzwa kuri 12mil (0.3mm), iyo inogona kugadzirwa nevazhinji vagadziri vePCB nemutengo wakaderera.

Mutsara upamhi mutsetse kutsemura hushoma kudzora kusvika 4 / 4mil, kuburikidza nemuboora kusarudzwa kwe8mil (0.2mm), inopfuura hafu yevagadziri vePCB vanogona kuburitsa, asi mutengo unenge uchidhura zvishoma kupfuura wepamberi.

Iyo shoma mutsara upamhi inodzorwa kusvika 3.5 / 3.5mil, uye gomba kusarudzwa i8mil (0.2mm). Vashoma pcb vagadziri vanogona kuburitsa pcb, uye mutengo unenge wave unodhura zvishoma.

Iyo shoma mutsara upamhi inodzorwa kusvika 2 / 2mil, uye gomba kusarudzwa kuri 4mil (0.1mm). Vazhinji vagadziri vePCB havagone kuiburitsa, uye mhando yemutengo iyi ndiyo yepamusoro.

Iyo tambo yakafara inogona kuseta zvinoenderana nePCB dhizaini dhizaini. Kana kuwanda kwacho kuri kushoma, upamhi hwemitsara uye nzvimbo yekumisidzana inogona kuiswa kuti ive yakakura. Kana huwandu hwacho hwakakura, hupamhi hwemitsara uye nzvimbo yekumisidzana inogona kuiswa kuti ive diki:

1) 8 / 8mil, 12mil (0.3mm) yekuzadza.

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

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

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

5) 3.5 / 3.5mil, 4mil kuburikidza mugomba (0.1mm, Laser kuchera).

6) 2 / 2mil, 4mil kuburikidza mugomba (0.1mm, Laser kuchera).
