Ntau qhov chaw nres tsheb yas cov xovxwm kub cov khoom siv qhia

Cov khoom tseem ceeb rau kev ua haujlwm ntawm cov khoom siv kub kub yog: qhov kub thiab siab}

Cov Lus Qhia Kev Lag Luam rau Ntau Cov Chaw Nres Tsheb Yas Cov Xovxwm Kub Khoom:

Rau kev vuam cov khoom lag luam, nws yog ib qho tseem ceeb heev uas yuav tau teeb tsa cov teeb meem saum toj no yog qhov ua rau cov khoom siv sib xyaw ua ke ntawm Weld cov khoom lag luam zoo {}}

FPC yog tsim ntawm ob txheej ntawm polyimide thiab tooj mi}} Nws tuaj yeem tiv thaiv lub taub hau thaum lub taub hau thaum lub taub hau siab thaum vuam (FPC thiab PCB thiab PCB thiab PCB Thaum tshav kub kub . Thaum lub siab lub taub hau tau nias, kev ntseeg siab ntawm welded cov taub hau yuav ua rau lub siab lub taub hau kom dissipate tshav kub) {8}

Ib qho ntxiv, cov tuab tuab ntawm FPC yog nruab nrab ntawm 0 {{}} 02 ~ 0 {} Yog li ntawd, muaj qhov ntsuas kub tau ntxiv thaum teeb meem kub. (Dab neeg Melting point ntxiv rau poob qhov kub).

Thib ob, teeb cua sov kub ntawm cov xovxwm kub:

Ua FPC thiab PCB ua ke sib txuas ua ke, thiab nws cov chaw teeb tsa yog nyob ntawm cov khoom siv tau welded {}.} teev qhov kub raws tus nqi ntawm tshav kub dissipation .

Nco tseg: Thaum cov electrolytic tso tooj liab ntawm FPC nyob hauv qab 0 {}}} nws tuaj yeem tsim qhov kub thiab txias uas tau melted kiag li.

Yog tias qhov ntsuas kub siab dhau lawm, qhov ntsuas kub tau sib kis mus rau qhov kub thiab txias}}} Nws yog qhov kub thiab txias dua

Cov hauv qab no yog cov nqi siv:

Thawj theem kub teeb tsa ntau hom txhuas-dawb: 230 txog 280: theem kub thib ib qho chaw ntau: 280 txog 350 degrees.

Thawj theem kub teeb tsa cov khoom lag luam txhuas

3. theem peb theem txias txias dua tom qab lub taub hau nce siab, FPC yuav sawv nrog lub taub hau siab, ua rau muaj lub taub hau siab tag nrho Txias txias tsawg dhau yuav txo ntau lawm kev ua tau zoo . Qhov kub thiab txias li 180 degrees.
