Solder mast bụ akụkụ dị mkpa nke PCB e biri ebi sekit mbadamba, Ọ dịghị obi abụọ na Solder nkpuchi ga-enyere aka mgbakọ, Otú ọ dị ihe ọzọ solder nkpuchi na-eme?Anyị ga-amatakwu maka ihe mkpuchi solder n'onwe ya.
Gịnị bụ ihe mkpuchi solder?
Ihe mkpuchi na-ere ihe ma ọ bụ ihe nkwụsị ihe mkpuchi ma ọ bụ ihe na-ere ahịa bụ ihe mkpuchi lacquer dị mkpa nke polymer nke a na-etinyekarị na akara ọla kọpa nke bọọdụ sekit e biri ebi (PCB) maka nchebe megide oxidation na iji gbochie àkwà mmiri na-ere ahịa ka ọ ghara ịmalite n'etiti paịlị ihe na-ekesa nke ọma. .
Akara mmiri na-ere ahịa bụ njikọ eletrik na-atụghị anya ya n'etiti ndị nduzi abụọ site na obere oghere nke ihe na-ere ahịa.
Ndị PCB na-eji ihe mkpuchi na-ere ihe iji gbochie nke a ime.
Ọ bụghị mgbe niile ka a na-eji ihe mkpuchi na-ere ihe maka mgbakọ ejiri aka na-ere, mana ọ dị mkpa maka bọọdụ ndị a na-emepụta nke ukwuu nke a na-ere ya na-akpaghị aka site na iji usoro ịsagharị ma ọ bụ usoro ịsa ahụ.
Ozugbo etinyere ya, a ga-emepe oghere na nkpuchi na-ere ihe n'ebe ọ bụla a na-ere ihe mejupụtara, nke a na-arụzu site na iji fotolithography.

Usoro nke solder nkpuchi
Usoro nkpuchi solder gụnyere ọtụtụ usoro.
Mgbe a tupu nhicha nzọụkwụ, nke e biri ebi sekit mbadamba na- degreased na ọla kọpa elu bụ ma mechanically ma ọ bụ chemically ike ọgwụgwụ, na solder nkpuchi na-etinyere.
Enwere ọtụtụ ngwa dị ka mkpuchi mkpuchi, mbipụta ihuenyo ma ọ bụ mkpuchi ịgba dị.
Mgbe ejiri nkpuchi na-ere ihe kpuchie PCB ndị ahụ, ihe mgbaze kwesịrị ka ekpochapụ ya ka ọ bụrụ ihe na-ehicha ya.
Nzọụkwụ na-esote n'usoro bụ ikpughe.Iji hazi ihe nkpuchi na-ere ihe, a na-eji ihe osise eme ihe. A na-ekpughe mbadamba ihe na-acha ọkụ ọkụ 360 nm.
Ebe ndị ahụ ekpughere ga-eme ka polymerize ebe ndị ekpuchiri ekpuchi ga-anọgide na-adị monomer.
