Highleap Electronic's Guide kune Mapofu uye Akavigwa Vias muPCBs

Mumamiriro ezvinhu emagetsi ari kuramba achichinja, mabhodhi edunhu akadhindwa (PCBs) anoshanda semusana wezvishandiso zvese zvemagetsi. Sezvo tekinoroji ichifambira mberi, kudiwa kwemaPCB akatetepa, anoshanda zvakanyanya, uye akavimbika kwawedzera. Chinhu chikuru pakuzadzisa zvinodiwa izvi zvivakwa zvehunyanzvi zvinozivikanwa sema "blind and buried vias". Gwaro iri rakazara rinotarisa muhunhu hwema "blind and buried vias", richibatanidza zvakadzama mashandisirwo eCAM engineering kuti ripe kunzwisisa kwakakwana kune mainjiniya, vagadziri, uye nyanzvi dzeindasitiri. Sekambani inotungamira yekugadzira nekugadzira maPCB , Highleap Electronic inonyanya kugadzira maPCB emhando yepamusoro eBlind and Buried Vias uye ma "blind and Buried Via circuit boards", ichivimbisa kurongeka uye kuvimbika mune yega yega purojekiti.

Chii chinonzi Mapofu uye Kuvigwa Vias?

Mapofu Vias

Blind vias inyanzvi dzekubatanidza dzinobatanidza imwe kana akawanda ekunze akaturikidzana ePCB kune akasarudzwa emukati akaturikidzana pasina kupinda mubhodhi rose. Kusiyana kuburikidza-gomba vias, izvo kuyambuka ose akaturikidzana, mapofu vias vari "mapofu" nokuti havaenderani kune mhiri PCB. Iyi yekubatanidza yakasarudzika inobvumira imwe compact dhizaini nekusunungura nzvimbo pane ekunze maseru ekuiswa kwechikamu uye nzira.

Kuvigwa Vias

Akavigwa vias, kune rumwe rutivi, aripo zvachose mukati memukati mezvikamu zvePCB, achibatanidza aya akaturikidzana pasina kusvika kune ekunze. Aya vias akavigwa zvachose kubva kumusoro uye pasi mativi bhodhi, achipa mukati kubatana kuti wedzera routing kuchinjika uye kuchengetedza yakachena zvokunze akaturikidzana kuti chikamu placement.

Zvikamu zveMapofu uye Akavigwa Vias

Mapofu uye akavigwa vias anogona kuiswa mumapoka zvichienderana nemaitiro avo ekugadzira uye masisitimu ezvimiro:

1. Mechanical Bofu Vias: Yakadhiriwa uchishandisa yakajairwa michina michina, aya vias anowanzo batanidza iyo yepamusoro layer kune imwe kana anopfuura akabatana emukati akaturikidzana.
2. Laser Bofu Vias: Yakagadzirwa uchishandisa precision laser drilling, inobvumira kunakisa kuburikidza nekuisa uye yakakwirira density.
3. Kuvigwa Vias: Inowanikwa zvachose mukati memukati memukati, ichibatanidza akawanda emukati machira pasina kupinda mukati mekunze.
4. Yakaturikidzana Vias: Nhepfenyuro yevias yakamisikidzwa yakatwasuka kuburikidza neakawanda akaturikidzana, inosimudzira yekubatanidza pasina kuwedzera PCB ukobvu.

Bofu uye Kuvigwa Vias CAM Injiniya Operation Specifications

Kuve nechokwadi chechokwadi uye kuvimbika mukugadzira PCB, CAM engineering mashandiro ekuita anotsanangura akadzama mafambiro uye zvinodiwa pakugadzira mapofu uye akavigwa vias. Aya mazano akakosha pakuwana kuita kunoenderana uye kunaka. Pazasi pane kubatanidzwa kweCAM engineering zvirevo zvakakosha pakugadzira Mapofu uye Akavigwa Vias PCBs paHighleap Electronic.
