Ts'ebetso ea chip ea SMT e na le lisebelisoa tsa bohlokoa tse thusang, ke pente ea solder.
Sebopeho sa solder paste haholo-holo se na le likaroloana tsa tin powder alloy le flux (flux e na le rosin, ntho e sebetsang, solvent, thickener, joalo-joalo), pente ea solder e tšoana le sesepa sa meno, se sebelisetsoang mochine oa khatiso oa solder paste sebakeng sa pcb pad, e le hore Mochini o beoang o beha likarolo tsa elektroniki tse khomarelang, ebe o reflow soldering mocheso o phahameng o chesang o qhibilihisang solder ebe o lokisa likarolo tsa elektroniki ho pad.
Solder peista ke hobane'ng ha ho khutlela mocheso susumetsang maikutlo?
1. Ke hobane'ng ha solder paste e hloka ho futhumala?
Solder peista e ka kakaretso bolokoa ka sehatsetsing (5-10 likhato Celsius) tikoloho, ho tloha sehatsetsing tla nkoa ka ntle ho SMT workshop tikoloho mocheso ho se lumellane, haeba ka ho toba bulehetse ho sebelisoa, ke ho se tsitse ho kopana mocheso, holim 'a solder peista. e tla khomarela mouoane oa metsi, haeba ho reflow soldering mocheso o phahameng, ho ka 'na ha bonahala eka ho phatloha thini, ho fella ka boleng bo bobe ba lifaha tsa thini.Ka hona, peista ea solder e nkiloeng ka sehatsetsing ka kakaretso e molemo ho khutlela mocheso oa 2-4H.
2. Ke hobane'ng ha motsoako oa solder o lokela ho tsosoa?
Solder peista beha ka sehatsetsing, ka lebaka la likarolo tse sa tšoaneng tsa peista solder, beha ka nako e telele, likarolo tse sa tšoaneng tsa ho peista solder tla hlaha layered ketsahalo, kahoo o lokela ho hlohlelletsa (ho hlohlelletsa ka tsela e tšoanang 20-30 reteleha. e ka ba), haeba e sa tsosoa ka ho toba le, joale likarolo tse sa tšoaneng tsa peista ea solder ha li kopane, li ke ke tsa bapala tšebeliso ea solder peista ka boeona.
Lebaka leo ka lona sehatsetsi sa solder se lokelang ho bolokoa ka sehatsetsing ho e-na le ho toba setšeng ke hore pente ea solder e na le li-solvents le rosin, e tla fetoha mouoane haeba e behoa ka ho toba tikolohong e tloaelehileng, kahoo e etsa hore moea o omelle.
Ho na le othomathike solder peista tsamaiso lik'habote 'marakeng, ho akarelletsa le polokelo, tempering le jarolla ka ho iketsa susumetsang maikutlo, joalo-joalo Haeba khampani e khōlō le sebelisa e ngata solder peista, u ka reka thepa e joalo ho laola le ho sebelisa solder peista.
