Hitamo ibikoresho byo gukwirakwiza ubushyuhe bwa 3-PCB

Guhitamo uburyo bukwiye bwo kugenzura ubushyuhe hamwe nubushyuhe bwo gukwirakwiza ubushyuhe bwa PCBs eshatu ni ngombwa kugirango ugabanye ubushyuhe bwibintu no kwemeza muri rusange gahunda ihamye. Mugihe ikoranabuhanga rigenda ritera imbere, ibikoresho bya elegitoronike biba bito kandi bigakomera, bigatuma ubushyuhe bwiyongera. Ibi birasaba ingamba zifatika zo gucunga ubushyuhe kugirango wirinde ubushyuhe bukabije nibikoresho bishobora kunanirwa.Muri iyi nyandiko ya blog, tuzakuyobora muburyo bwo guhitamo ibikoresho bikwiye byo kugenzura ubushyuhe no gukwirakwiza ubushyuhe muri PCB-3.

1. Sobanukirwa n'akamaro ko gucunga amashyuza

Imicungire yubushyuhe ningirakamaro kugirango habeho imikorere yizewe yibikoresho bya elegitoroniki. Ubushyuhe bukabije bushobora gutuma imikorere igabanuka, kongera ingufu, no kugabanya ubuzima bwa serivisi. Gukonjesha neza ni ngombwa kugirango ubushyuhe bwibigize bugabanuke. Kwirengagiza imicungire yubushyuhe birashobora kugutera guhangayikishwa nubushyuhe, kwangirika kwibigize, cyangwa no gutsindwa gukabije.

2. Ibyingenzi Byibanze kubikoresho byo kugenzura ubushyuhe

Mugihe uhitamo ibikoresho byo gucunga ubushyuhe bwa 3-PCBs, hagomba gusuzumwa ibintu bikurikira:

- Amashanyarazi yubushyuhe:Ubushobozi bwibikoresho byo gutwara ubushyuhe birakomeye. Ubushyuhe bwo hejuru bwumuriro vuba vuba ubushyuhe buva mubice bikikije ibidukikije. Ibikoresho nkumuringa na aluminiyumu bikoreshwa cyane kubera imiterere yubushyuhe bwiza.

- Gukoresha amashanyarazi:Kubera ko ibice 3 bya PCB birimo ibice byinshi hamwe nibikoresho bya elegitoroniki bitandukanye, ni ngombwa guhitamo ibikoresho bitanga amashanyarazi meza. Ibi birinda imiyoboro migufi nandi makosa yamashanyarazi muri sisitemu. Ibikoresho byo gucunga ubushyuhe hamwe nibikoresho byiza byamashanyarazi bikundwa, nka ceramics cyangwa silicon-ivanze.

- Guhuza:Ibikoresho byatoranijwe bigomba guhuzwa nuburyo bwo gukora bukoreshwa mu kubyara PCB-3. Bagomba kuba babereye kumurika kandi bakagira neza kubindi bice bya PCB.

3. Shyushya ibikoresho byo gukwirakwiza PCB-3

Kugirango uzamure imikorere yubushyuhe bwa 3-layer PCB, ibikoresho bitandukanye nikoranabuhanga birashobora gukoreshwa:

- Ibikoresho bya Thermal Interface (TIM):TIM igabanya ubukana bwumuriro mugutezimbere ubushyuhe hagati yibice hamwe nubushyuhe. Ibi bikoresho byuzuza icyuho cya microscopique hagati yubuso kandi biza muburyo butandukanye, harimo amashanyarazi, geles, paste nibikoresho byo guhindura ibyiciro. Guhitamo TIM biterwa nibintu nkubushyuhe bwumuriro, guhoraho no gukora.

- Imirasire:Imirasire itanga ubuso bunini bwo gukwirakwiza ubushyuhe. Mubisanzwe bikozwe muri aluminiyumu cyangwa umuringa kandi bifatanye nibice byinshi byifashishwa bifata ibyuma bifata ubushyuhe cyangwa imashini. Gushushanya ibishushanyo mbonera no kubishyira bigomba kunozwa kugirango ubushyuhe bugabanuke.

- Imiterere yinama yumuzunguruko:Imiterere ya PCB ikwiye igira uruhare runini mugukwirakwiza ubushyuhe. Guteranya imbaraga-nyinshi hamwe hamwe no kwemeza umwanya uhagije hagati yazo zituma umwuka mwiza ugenda neza kandi bikagabanya ubushyuhe bwinshi. Gushyira ibice byo gushyushya hafi yinyuma ya PCB biteza imbere ubushyuhe bwiza binyuze muri convection.

- Vias:Vias irashobora gushyirwaho muburyo bwo kuyobora ubushyuhe buva mubice byimbere bya PCB kugeza kumurongo winyuma cyangwa kumuriro. Iyi vias ikora inzira yubushyuhe kandi ikongerera ubushyuhe. Guhitamo neza no gukwirakwiza vias ningirakamaro muburyo bwiza bwo gucunga neza ubushyuhe.

4. Hindura uburyo bwiza bwa sisitemu binyuze mugucunga neza ubushyuhe

Ihungabana rya sisitemu ya PCB igizwe na 3 irashobora kunozwa cyane binyuze muguhitamo neza no gushyira mubikorwa ibikoresho bikwiye byo gucunga ubushyuhe. Imicungire ihagije yubushyuhe igabanya ibyago byo gushyuha kandi ikanaramba kuramba kwibikoresho bya elegitoronike, bityo sisitemu ikizere.

Muri make

Guhitamo neza imicungire yubushyuhe hamwe nubushyuhe bwo gukwirakwiza ubushyuhe bwa PCB igizwe na 3 ni ngombwa kugirango wirinde ubushyuhe bwinshi no kwemeza sisitemu ihamye. Gusobanukirwa n'akamaro ko gucunga amashyuza, urebye ibintu nkubushyuhe bwumuriro nubushyuhe bwamashanyarazi, hamwe no gukoresha ibikoresho nka TIM, ibyuma bishyushya ubushyuhe, imiterere yubuyobozi bwiza, hamwe na vias byashyizwe mubikorwa ni intambwe zingenzi mugushikira uburyo bwiza bwo kugenzura ubushyuhe. Mugushira imbere imicungire yubushyuhe, urashobora kurinda imikorere no kuramba kwibikoresho bya elegitoroniki.
