Hitamo ibikoresho bibereye PCB nyinshi

Muri iyi nyandiko ya blog, tuzaganira kubitekerezo byingenzi nubuyobozi bwo guhitamo ibikoresho byiza kuri PCB nyinshi.

Mugushushanya no kubyara imbaho ​​zumuzunguruko, kimwe mubintu byingenzi ugomba gusuzuma ni uguhitamo ibikoresho byiza.Guhitamo ibikoresho bikwiye kubibaho byumuzunguruko, harimo substrate na fayili yumuringa, birashobora guhindura cyane imikorere nubwizerwe bwibicuruzwa byanyuma.

Sobanukirwa n'uruhare rwa substrate

Ibikoresho shingiro nishingiro ryibibaho byinshi byumuzunguruko.Ifite uruhare runini mugutanga inkunga yubukanishi, gukwirakwiza amashanyarazi no gukwirakwiza ubushyuhe mu kibaho cyumuzunguruko.Kubwibyo, guhitamo substrate iburyo ningirakamaro kugirango tumenye neza muri rusange imikorere yimikorere yumuzunguruko.

Mugihe uhisemo substrate kubibaho byumuzunguruko, hari ibintu byinshi ugomba gusuzuma.Inzira zikoreshwa cyane zirimo FR-4, polyimide nibikoresho bya ceramic.Buri kintu gifite imiterere yihariye ninyungu zijyanye nibisabwa bitandukanye byumuzunguruko.

1. FR-4:FR-4 ni substrate ikoreshwa cyane izwiho kuba ifite amashanyarazi meza kandi akomeye.Igizwe nigice cyoroshye cya epoxy resin ikomeza fiberglass.FR-4 irahendutse, iraboneka byoroshye, kandi irakwiriye kubisabwa byinshi.Nubwo bimeze bityo ariko, bitewe na dielectric ihoraho kandi igahinduka igihombo, ntishobora kuba ibereye gushushanya imirongo myinshi.

2. Polyimide:Polyimide nibyiza kubisabwa bisaba guhinduka, kurwanya ubushyuhe bwinshi, no kurwanya imiti myiza.Nibikoresho bya termoplastique bishobora kwihanganira imikorere mibi.Ikibaho cyumuzunguruko wa polyimide gikunze gukoreshwa mubirere byindege, ibinyabiziga nubuvuzi aho ibishushanyo byoroheje kandi byoroshye ari ngombwa.

3. Ibikoresho by'ibumba:Kubisabwa bidasanzwe bisaba ubushyuhe bwumuriro mwinshi hamwe nubushakashatsi bwiza bwamashanyarazi, ibikoresho bya ceramique nka nitride ya aluminium cyangwa aluminium oxyde niyo ihitamo ryambere.Ibi bikoresho bifite ibikoresho byiza byumuriro kandi birashobora gukora imbaraga nyinshi.

Suzuma Amahitamo Yumuringa

Umuringa wambaye umuringa ukora nk'urwego ruyobora mu mbaho ​​nyinshi.Itanga inzira z'amashanyarazi no guhuza ibice bitandukanye hamwe nizunguruka.Iyo uhisemo umuringa wambaye umuringa, hari ibintu bibiri byingenzi ugomba gusuzuma: uburebure bwa file nubwoko bufatika.

1.Umubyimba wuzuye:Umuringa wambaye umuringa uza mubwinshi butandukanye, mubisanzwe kuva kuri 1 ounci 6.Umubyimba ugena ubushobozi bwo gutwara ikibaho cyumuzunguruko.Ifu yuzuye irashobora gutwara imitwaro ihanitse ariko irashobora kugarukira mugushikira ubugari bwiza bwumwanya hamwe nintera.Niyo mpamvu, ni ngombwa gusuzuma ibisabwa byubu byumuzunguruko hanyuma ugahitamo ubunini bwa file buzuza ibisabwa bihagije.

2.Ubwoko bufatika:Umuringa wambaye umuringa hamwe na acrylic cyangwa epoxy yometseho.Ifumbire ya Acrylic ifata neza ibidukikije, byoroshye kuyitunganya kandi birahendutse.Epoxy ifata ifu, kurundi ruhande, itanga ubushyuhe bwiza bwumuriro, imiti irwanya imiti, hamwe na adhesion.Guhitamo ubwoko bufatika biterwa nibisabwa byihariye bya porogaramu.

Hindura uburyo bwo guhitamo ibikoresho

Kugirango uhindure uburyo bwo gutoranya ibikoresho kubibaho byinshi byumuzunguruko, hagomba gusuzumwa amabwiriza akurikira:

1. Menya ibisabwa:Nibyingenzi kumva ibidukikije bikora, ubushyuhe buringaniye, guhangayikishwa nubukanishi, nibindi bintu byihariye bijyanye na porogaramu.Aya makuru azayobora guhitamo ibikoresho bishobora kwihanganira ibisabwa.

2.Korana nabatanga isoko:Kugisha inama hamwe nuburambe bwibikoresho bitanga cyangwa uruganda rwa PCB birashobora gutanga ubushishozi bwingenzi muguhitamo ibikoresho bikwiye.Barashobora gutanga inama zishingiye kubuhanga bwabo nubumenyi bwiterambere rigezweho mubikoresho byubuyobozi bwumuzunguruko.

3. Suzuma ikiguzi no kuboneka:Mugihe imikorere no kwizerwa ari ngombwa, ni ngombwa nanone gusuzuma ikiguzi no kuboneka kubikoresho byatoranijwe.Menya neza ko ibikoresho byatoranijwe bidahenze kandi byoroshye kuboneka muburyo bukenewe.

Muri make

Guhitamo ibikoresho bibereye PCB nyinshi nintambwe yingenzi mugukora neza, kwizerwa no gukora ibicuruzwa byanyuma.Gusobanukirwa uruhare rwa substrate hamwe nu muringa, gusuzuma amahitamo ashingiye kubisabwa byihariye, no guhitamo uburyo bwo gutoranya bizafasha abashushanya n'ababikora kugera kubisubizo byiza.Mugusuzuma aya mabwiriza, injeniyeri arashobora guhitamo yizeye neza ibikoresho bikwiye kubibaho byinshi byumuzunguruko, bikavamo ibicuruzwa byiza kandi biramba.
