Gukemura impande zombi pcb kwagura ubushyuhe nibibazo byubushyuhe

Urimo guhura nubushyuhe bwumuriro nibibazo byubushyuhe hamwe na PCBs zimpande ebyiri? Ntukongere kureba, muriyi nyandiko ya blog tuzakuyobora muburyo bwo gukemura ibyo bibazo neza. Ariko mbere yo kwibira mubisubizo, reka twimenyekanishe.

Capel ni uruganda rufite ubunararibonye mu nganda zumuzunguruko kandi rumaze imyaka 15 rukorera abakiriya. Ifite uruganda rwumuzunguruko rworoshye, uruganda rwumuzunguruko rukomeye rwa flex, uruganda rukora imbaho ​​za smt, kandi rumaze kumenyekana neza mugukora ibicuruzwa byujuje ubuziranenge hagati-kugeza hejuru-byanyuma. Ibikoresho byacu byambere byatumijwe mu mahanga byuzuye-byikora kandi byitiriwe R&D byerekana ubushake bwacu bwo kuba indashyikirwa. Noneho, reka dusubire gukemura ikibazo cyo kwagura ubushyuhe hamwe nubushyuhe bwumuriro kuri PCB ebyiri.

Kwiyongera k'ubushyuhe hamwe nubushyuhe bwumuriro nibibazo bisanzwe mubikorwa bya PCB. Ibi bibazo bivuka kubera itandukaniro muri coefficient yo kwagura ubushyuhe (CTE) bwibikoresho bikoreshwa muri PCB. Iyo ashyushye, ibikoresho biraguka, kandi niba igipimo cyo kwaguka cyibikoresho bitandukanye gitandukanye cyane, guhangayika birashobora gutera imbere bigatera PCB kunanirwa. Kugira ngo ibibazo nkibi bikemuke, nyamuneka kurikiza aya mabwiriza:

1. Guhitamo ibikoresho:

Hitamo ibikoresho bihuye nagaciro ka CTE. Ukoresheje ibikoresho bifite ibipimo bisa byo kwaguka, amahirwe yo guhangayikishwa nubushyuhe nibibazo bijyanye no kwaguka arashobora kugabanuka. Baza abahanga bacu cyangwa ubaze amahame yinganda kugirango umenye ibikoresho byiza kubisabwa byihariye.

2. Ibishushanyo mbonera:

Reba imiterere ya PCB nigishushanyo kugirango ugabanye ubushyuhe bwumuriro. Birasabwa kugumana ibice bikwirakwiza ubushyuhe kure y’ibice bifite ihindagurika ryinshi ry’ubushyuhe. Gukonjesha neza ibice, ukoresheje ubushyuhe bwumuriro, hamwe no gushiramo ubushyuhe birashobora kandi gufasha kugabanya ubushyuhe neza no kugabanya imihangayiko.

3. Gutondekanya ibice:

Igice cya stackup ya PC-impande ebyiri PCB igira ingaruka kumyitwarire yubushyuhe. Kuringaniza no guhuza bifasha gukwirakwiza ubushyuhe buringaniye, kugabanya amahirwe yo guhangayika. Baza injeniyeri zacu kugirango utezimbere kugirango ukemure ibibazo byawe byo kwagura ubushyuhe.

4. Umubyimba wumuringa hamwe nu nsinga:

Umubyimba wumuringa nubugari bwumurongo bigira uruhare runini mugucunga ubushyuhe bwumuriro. Umuringa wimbitse utanga ubushyuhe bwiza kandi birashobora kugabanya ingaruka zo kwaguka. Mu buryo nk'ubwo, inzira nini zigabanya kurwanya no gufasha mu gukwirakwiza ubushyuhe bukwiye.

5. Guhitamo ibikoresho byibanze nibikoresho byingenzi:

Hitamo prereg hamwe nibikoresho byibanze hamwe na CTE bisa nu muringa wambaye kugirango ugabanye ingaruka zo gusibanganya bitewe nubushyuhe bwumuriro. Byakize neza kandi bihujwe prereg hamwe nibikoresho byingenzi nibyingenzi mukubungabunga ubusugire bwimiterere ya PCB.

6. Kugenzura inzitizi:

Kugumana inzitizi zagenzuwe muburyo bwa PCB bifasha gucunga ibibazo byumuriro. Mugumya inzira yinzira ngufi kandi wirinde impinduka zitunguranye mubugari bwumurongo, urashobora kugabanya impinduka zatewe no kwaguka kwinshi.

7. Ikoranabuhanga ryo gucunga ubushyuhe:

Gukoresha uburyo bwo gucunga ubushyuhe nkubushyuhe, amashanyarazi, hamwe nubushyuhe bwumuriro birashobora gufasha gukwirakwiza ubushyuhe neza. Izi tekinoroji zitezimbere muri rusange imikorere yubushyuhe bwa PCB kandi bigabanya ibyago byo kunanirwa nubushyuhe buterwa no kunanirwa.

Mugushira mubikorwa izi ngamba, urashobora kugabanya cyane kwaguka kwumuriro nibibazo byubushyuhe bwumuriro muri PCB zombi. Kuri Capel, dufite ubuhanga nubushobozi bwo kugufasha gutsinda ibyo bibazo. Itsinda ryacu ryinzobere rirashobora gutanga ubuyobozi ninkunga zingirakamaro kuri buri cyiciro cyibikorwa bya PCB.

Ntukemere kwaguka k'umuriro hamwe nubushyuhe bwumuriro bigira ingaruka kumikorere ya PCB yawe impande zombi. Menyesha Capel uyumunsi kandi wibonere ubuziranenge nubwizerwe buzanwa nuburambe bwimyaka 15 mubikorwa byubuyobozi bwumuzunguruko. Reka dufatanye kubaka PCB yujuje kandi irenze ibyo witeze.
