Seo U Lokelang ho se Tseba ka Selective Wave Soldering?

Mefuta ea khethomochini oa solder

Selectional wave soldering e arotsoe ka mefuta e 'meli: motlakase oa maqhubu a khethiloeng ntle le marang-rang le marang-rang a khethang marang-rang.

Offline khethang maqhubu solder: off-line ho bolela off-line le line tlhahiso.Mochini oa ho fafatsa oa Flux le mochini o khethang oa welding o arotsoe ka 1 + 1, moo mochini oa preheating o latelang lefapha la welding, phetisetso ea letsoho, motsoako oa mochini oa motho, lisebelisoa li nka sebaka se senyenyane.

Online khethang ho tsona leqhubu soldering: online tsamaiso ka fumana ya data line tlhahiso ka nako ea sebele le docking ka ho feletseng jarolla ka ho iketsa, tjheseletsa flux mojulung preheating mojule tjheseletsa mojulung o kopanetsweng sebopeho, tšoauoa ka jarolla ka ho iketsa ketane phetiso, thepa nka sebaka se seholo, a loketse bakeng sa boemo bo phahameng itirisang tsa tlhahiso.

 

Melemo le melemo ea mochini o khethang oa solder

Khetho ea welding e na le melemo e latelang ea litšenyehelo:

Thepa e nyane e nka sebaka

Tšebeliso e fokolang ea matla

Ho boloka chelete e ngata

Ho fokotsa haholo tlhahiso ea tin slag

Ho fokotsa tšebeliso ea naetrojene haholo

Ha ho litšenyehelo tsa ho lokisa tse etsoang

 

Khetho ea welding e na le mefokolo e latelang:

1. Theko e phahameng ea theko

Lebaka le leng ke hore mosebetsi oa ho khetha leqhubu la motlakase o rarahane ho feta oa maqhubu a tloaelehileng, kahoo mohaho oa mochine o tla ba o rarahaneng le litšenyehelo tsa tlhahiso li phahametse.Lebaka le leng ke hore mochini o sebelisoang haholo oa ho khetha maqhubu e ntse e le lihlahisoa tse tsoang kantle ho naha.Qalong ea libaka, tlhokahalo ea 'maraka e ntse e eketseha butle-butle 'me tlhōlisano ea' maraka e ntse e eketseha butle-butle.

2. Ts'ebetso e tlaase

Molemo oa ho khetha leqhubu soldering ka solder kopanetsoe taolo boleng ke ea bohlokoa haholo, empa ka nako e tšoanang e bapisoa le tloaelehileng leqhubu soldering tlhahiso e totobetse haholo, khaello ea ka holimo e le nozzle ka nako e tšoanang e ka ba feela solder. tjheseletsa, le hoja ba bang ba mechine e, ka phaella ka ho re palo ea nozzle ho eketsa tlhahiso, empa ka tlhahiso ke khaello ea bohlokoa ea ho khetha leqhubu soldering.

Tlhokomelo e ikhethileng ea li-soldering

1. Wave soldering thepa ea ho tsofala ha tlhokomelo, tlhokomelo ea motlakase, tlhokomelo ea lisebelisoa holim'a lisebelisoa.

Lekola letlooa la sekoaelo sa sekoaelo sa flux 'me u felise masala a mangata a phoroselang, letlooa la flux filter le hloekisoa ka metsi hang ka beke, hloekisa hood ea ho qeta beke e 'ngoe le e 'ngoe, hlahloba hore na spray e tšoana.Nozzle e lokela ho hloekisoa letsatsi le leng le le leng, mokhoa ke ho kenya joala ka har'a silinda e nyane ea flux, bula valve ea bolo, koala valve ea bolo ea silinda e kholo ea flux, qala ho fafatsa metsotso e 5-10, u tlose molomo beke e 'ngoe le e 'ngoe. , soak ka metsing ka lihora tse peli, hlahloba hore na sebōpi sa thini se nang le oxidized phofo e ntšo, slag e nang le oxidized e ngata haholo.

2. Nako e 'ngoe le e' ngoe ea hora e le 'ngoe ea ts'ebetso ea lisebelisoa tsa wave welding, e lokela ho hlahloba palo ea phofo e ntšo ea oxidation ea tin, le ho lutla ha sopho ho tla tsoa ho tin slag.

3. Ho bokella oxide e ngata haholo ka tanka ea tin ho tla baka ho se tsitse ha leqhubu la tiiso, ho phatloha ha tanka ea tin, esita le ho emisa koloi le mathata a mang.

4. Hona joale, lokolla sekoti se lokisa molomo, tlosa molomo, 'me u tlose slag ea tin ka hare ho molomo.
