Ịzụ ihe efu pụtara na akụrụngwa, ọkachasị ihe ndị nwere pin anaghị arị elu, nke a na-akpọ soldering efu, soldering efu nwere isi ihe asatọ ndị a:
1.Imeghe stencil na-adịghị mma
N'ihi na pin spacing bụ nnọọ ok, otú oghere dị nnọọ obere, ma ọ bụrụ na oghere oghere nkenke bụ ihe ọjọọ ga-eduga mado enweghị ike leaked ma ọ bụ ntapu e biri ebi nnọọ obere, dapụtara na mpe mpe akwa ọ dịghị mado, soldering mgbe ọdịdị nke. efu solder.
Ngwọta: stencil mepere emepe ziri ezi
2. Solder mado ọrụ adịghị ike
Solder mado n'onwe ya nsogbu adịghị ike, solder tapawa adịghị mfe na-ekpo ọkụ gbazee
Ngwọta: Dochie tapawa solder na-arụ ọrụ
3. Scraper nrụgide dị elu
Solder mado ka ihihi e biri ebi mkpuchi na pcb mpe mpe akwa, mkpa scraper azụ na apụta scraping ọzọ, ma ọ bụrụ na scraper mgbali na ọsọ, na solder mado ntapu ga-adị ntakịrị, na-ebute ihe efu solder.
Ngwọta: dozie nrụgide na ọsọ nke scraper
4. Ngwakọta atụdo warp deformation
Ụfọdụ akụrụngwa atụdo na-adọkpụ ma ọ bụ nwee nkwarụ n'ụzọ, na-akpata na-ekpo ọkụ gbazee solder mado enweghị ike ịrị tin, butere ihe efu solder.
Ngwọta: nwalee tupu ojiji wee jiri
5. Unyi ma ọ bụ oxidized pcb ọla kọpa foil
Ihe mkpuchi ọla kọpa pcb ruru unyi ma ọ bụ oxidized, na-ebute ntụtụ na-adịghị mma, na-eduga na ire ere efu.
Ngwọta mgbochi: pcb kwesịrị iji ngwa ngwa o kwere mee ka emepechara, a ga-esi ya ma nyochaa tupu eji ya.
6. Igwe na-agbagharị agbagharị Mpaghara preheat na-ekpo ọkụ ngwa ngwa
Mpaghara ebe a na-ekpo ọkụ na-agbagharị agbagharị na-ekpo ọkụ nke ukwuu, na-ebute tapawa solder agbazere na ebe a na-ekpo ọkụ na ebe a na-ere ere ekpochapụla.
Ngwọta mgbochi: tọọ usoro okpomọkụ nke ọkụ nwere ezi uche
7. igwe SMTakụrụngwa ntinye ego akwụ ụgwọ
N'ihi na oghere ntụtụ dị oke oke, ụfọdụ igwe nhazi nkenke enweghị ike iru, na-eduga n'itinye nkwụghachi, ọ bụghị ntinye ntụtụ na mpe mpe akwa ahapụtara.
Ngwọta mgbochi ụzọ: zụta ihe mgbago ziri ezi dị elu
8. Solder mado obibi akwụkwọ akwụ ụgwọ
Solder mado ebipụta igwe obibi akwụ ụgwọ, nwere ike ịbụ ihe kpatara stencil, nwekwara ike ịbụ mwekota efere rụrụ arụ.
Ngwọta: dozie igwe eji ebi akwụkwọ na-ebi akwụkwọ, dozie ihe ndozi tebụl tebụl maka mgbanwe.
