Gịnị bụ Bridging

Njikota

Njikọ Bridge bụ otu n'ime ntụpọ nkịtị na mmepụta SMT.Ọ ga-eme ka mkpirisi sekit dị n'etiti akụrụngwa, ọ ga-arụkwa ya mgbe ọ zutere njikọ akwa.Enwere ọtụtụ ihe kpatara njikọ akwa mmiri

1) Quality nsogbu nke solder mado

① Ọdịnaya igwe dị na tapawa solder dị elu, karịsịa ma ọ bụrụ na oge mbipụta ahụ dị ogologo, ọ dị mfe ịbawanye ọdịnaya ígwè, na-eme ka IC pin bridging;

② The solder tapawa nwere ala viscosity na tojuru n'èzí nke solder pad mgbe preheating;

③ Ndobe nke ụlọ elu tapawa na-ere ahịa adịghị mma, ọ na-ejupụtakwa n'èzí ebe a na-ere ihe mgbe ọ kpochara ọkụ;

Ngwọta: dozie oke nke tapawa ihe na-ere ihe ma ọ bụ jiri tapawa ihe na-ere ihe dị elu.

2) Usoro mbipụta

① The ugboro ugboro ziri ezi nke na-ebi akwụkwọ igwe adịghị mma, na alignment bụ ọbụna (ígwè efere alignment adịghị mma, PCB alignment adịghị mma), nke na-eme ka solder mado na-ebipụta n'èzí mpe mpe akwa, karịsịa mma pitch QFP pad;

② A naghị edozi nha na ọkpụrụkpụ nke windo ndebiri nke ọma, yana mkpuchi Sn Pb alloy nke PCB pad design abụghị otu, nke na-eduga na tapawa nke ukwuu.

Ngwọta: dozie ngwa nbipute ma melite mkpuchi PCB.

3) Ọ bụ ihe a na-emekarị na mmepụta na tapawa solder zuru oke mgbe a na-agbanye ya n'ihi oke nrụgide.Na mgbakwunye, ọ bụrụ na ntinye ziri ezi ezughị, ihe ndị ahụ ga-agbanwe ma pin IC ga-emebi.

4) The reflow oven kpo oku ọnụego bụ oke ngwa ngwa, ihe mgbaze na solder mado enweghị oge volatilize.

Ngwọta: dozie ịdị elu nke axis Z nke SMT yana ọnụego kpo oku nke ọkụ reflow.

Edemede na foto sitere na ịntanetị, ọ bụrụ na mmejọ ọ bụla pls buru ụzọ kpọtụrụ anyị ka ihichapụ.
NeoDen na-enye azịza ahịrị ahịrị SMT zuru ezu, gụnyere SMT reflow oven, igwe na-ere ọkụ, igwe na-eburu na ebe, igwe nbipute solder, PCB loader, PCB unloader, mgbawa mgbawa, igwe SMT AOI, igwe SMT SPI, igwe SMT X-Ray, SMT mgbakọ ahịrị akụrụngwa, PCB mmepụta Equipment SMT akụkụ mapụtara, wdg ụdị ọ bụla SMT igwe ị nwere ike chọrọ, biko kpọtụrụ anyị maka ozi ndị ọzọ:
