Moemeli oa ho Hloekisa Liindasteri
Moemeli oa ho hloekisa ka metsi ST-300.
Tlhaloso ea Sehlahisoa
Ho hlahisa mochine oa ST-300 oa ho hloekisa metsi, e leng tharollo ea phetoho bakeng sa indasteri ea lisebelisoa tsa elektroniki. Sesebelisoa sena se matla sa ho hloekisa ha se tšoane le tse ling tse 'marakeng, kaha ha se na litlhare tse chefo kapa li-inorganic acid le alkali. Ha e le hantle, e batla e sa nke lehlakore, e etsa hore e be khetho e sireletsehileng le e tsitsitseng haholoanyane bakeng sa litlhoko tsa ho hloekisa indasteri.
Mochine oa ho hloekisa oa ST-300 o entsoe ka mefuta e fapaneng ea li-surfactants tse khethehileng, e leng se etsang hore e be e 'ngoe ea mekhoa e metle ka ho fetisisa ea ho hloekisa e thehiloeng ho solvent e sebelisoang haholo indastering ea lisebelisoa tsa elektronike. Ha e fane feela ka phello e ntle ea tlhoekiso ho masala a flux le solder paste, empa e ka sebelisoa ho hloekisa liketane tsa solder, lisebelisoa, mesh ea tšepe le tse ling. Sesebelisoa sena sa ho hloekisa se feto-fetohang se fetolang lipapali bakeng sa lik'hamphani tse batlang ho ntlafatsa mekhoa ea tsona ea ho hloekisa ha li ntse li fokotsa tšusumetso ea tsona tikolohong.
E 'ngoe ea likarolo tse ka sehloohong tsa mochine oa ho hloekisa oa ST-300 ke monko oa eona o tlaase, e leng phetoho e amohelehang bakeng sa basebetsi ba atisang ho ba le monko o bohale oa lik'hemik'hale libakeng tsa indasteri. Sena se etsa hore sebaka sa mosebetsi se be monate le ho phutholoha, ha se ntse se fana ka ts'ebetso e ikhethang ea ho hloekisa.
Ntle le moo, mochini oa ho hloekisa oa ST-300 o na le bokhoni bo phahameng ba ho hloekisa, ho bolelang hore o khona ho sebetsana le mesebetsi e thata ea ho hloekisa ntle le ho hloka ho nkeloa sebaka khafetsa. Sena ha se boloke nako le chelete feela empa se boetse se fokotsa litšila, se etsa hore e be khetho e tsitsitseng bakeng sa likhoebo tse amehileng ka sebaka sa tsona sa tikoloho.
Ho feta moo, bophelo bo bolelele ba ts'ebeletso ea mohloekisi oa ST-300 bo bolela hore lik'hamphani li ka itšetleha ka eona bakeng sa tlhoekiso e tsitsitseng, ea boleng bo holimo ka nako e telele. Sena se fokotsa tlhokeho ea ho nchafatsa lihlahisoa khafetsa, ho etsa hore e be tharollo e theko e tlaase bakeng sa likhoebo tsa boholo bo fapaneng.
Ka kakaretso, setsi sa ho hloekisa metsi se nang le tikoloho ea ST-300 ke mokhoa o mong o phahameng ho feta oa setso oa ho hloekisa o thehiloeng ho solvent. Bokhoni ba eona bo matla ba ho hloekisa, bo kopantsoeng le monko oa eona o tlase, boima bo phahameng ba ho hloekisa, le bophelo bo bolelele ba ts'ebeletso, bo e etsa khetho e nepahetseng bakeng sa lik'hamphani tse batlang ho ntlafatsa lits'ebetso tsa tsona tsa ho hloekisa ha li ntse li etelletsa pele ho boloka tikoloho.
Hore na o indastering ea lisebelisoa tsa elektroniki kapa maemong afe kapa afe a liindasteri tse hlokang ts'ebetso ea boemo bo holimo, mochini oa ho hloekisa oa ST-300 o fetola papali. Alumelisa monko o matla oa lik'hemik'hale le metsoako e chefo, 'me u lumelise bokamoso bo hloekileng, bo botala ka mochini oa ho hloekisa oa ST-300.

Tšebeliso le Tlhokomelo
1. Haholo-holo e sebelisetsoa ho hloekisa li-residual soldering flux holim'a liboto tsa PCB, liketane tsa solder tsa wave, li-fixtures, li-steel mesh solder paste hloekisa, joalo-joalo.
2. Ho molemo ho sebelisa mocheso oa ultrasonic ho 45-80 ℃ bakeng sa liphello tse molemo.
3. Ka mor'a ho hloekisa ka ST-300, ho molemo ho hlatsoa ka ho feletseng ka metsi.
