Amanqaku okusebenza kwezixhobo zokuthambisa zamaza
1. Ubushushu be-soldering besixhobo sokuthengisa amaza

Iqondo lobushushu le-soldering lesixhobo sokuthengisela amaza libhekiselele kwiqondo lobushushu lobuchwephesha betekhnoloji yokuthengisa kwindawo yokukhupha umlomo.Ngokubanzi, iqondo lobushushu liyi-230-250℃, kwaye ukuba iqondo lobushushu liphantsi kakhulu, amalungu e-solder arhabaxa, atsalwa kwaye awaqaqambi.Ide ibangele i-welding ebonakalayo kunye ne-incandescence yobuxoki;ukuba iqondo lobushushu liphezulu kakhulu, kulula ukukhawulezisa i-oxidation, deform ibhodi yesekethe eprintiweyo, kwaye utshise onke amacandelo.Ukulungiswa kweqondo lokushisa kufuneka kulungiswe ngokwezinto eziphathekayo kunye nobukhulu bebhodi eprintiweyo, ubushushu be-ambient, kunye nesantya sebhanti yokuhambisa.

2. Susa i-tin slag kwi-wave soldering oven kwangethuba

Itoti ekwibhafu yetoti yesixhobo sokuphinda yenze ii-oxides xa idibana nomoya ixesha elide.Ukuba i-oxides iqokelela kakhulu, iya kutshizwa kwibhodi eprintiweyo kunye ne-tin phantsi kwesenzo sempompo.I-Bit solder joints kwi-luster.Ibangela iziphene ezifana nolawulo lwe-slag kunye nokubopha ibhulorho.Ngoko ke, kuyimfuneko ukususa i-oxides rhoqo (ngokuqhelekileyo rhoqo kwiiyure ezi-4).Ii-Antioxidants zinokongezwa kwi-solder etyhidiweyo.Oku akuthinteli kuphela i-oxidation kodwa kunciphisa i-oxide kwi-tin.

3. Umphakamo we-wave crest yesixhobo sokuthengisa amaza

Ukuphakama kwamaza esixhobo sokuthengisa amaza kulungelelaniswa ngcono kwi-1/2-1/3 yobukhulu bebhodi eprintiweyo.Ukuba i-wave crest iphantsi kakhulu, iya kubangela ukuvuza kwe-solder kunye ne-tin ejingayo, kwaye ukuba i-wave crest iphezulu kakhulu, iya kubangela i-tin eninzi kakhulu.Amalungu ashushu kakhulu.

4. Isantya sokuhanjiswa kwezixhobo zokuthambisa zamaza

Isantya sothumelo lwesixhobo sokuthengisa amaza silawulwa ngokubanzi kwi-0.3-1.2m/s.Kumiselwe kwimeko nganye.Ebusika, xa ibhodi yesekethe eprintiweyo inemigca ebanzi, amacandelo amaninzi, kunye nomthamo omkhulu wokushisa wamacandelo.Isantya sinokucotha kancinane;isantya esingasemva sinokukhawuleza.Ukuba isantya sikhawuleza kakhulu, ixesha le-welding lifutshane kakhulu.Kulula ukubangela i-phenomenon ye-welding yendlu, i-welding yobuxoki, i-welding engekhoyo, i-bridging, i-bubbles air, njl.;isantya sicotha kakhulu.Ixesha le-welding lide kakhulu kwaye ubushushu buphezulu kakhulu.Iibhodi zesekethe eziprintiweyo ngokulula kunye namacandelo.

5. I-angle yokuhanjiswa kwezixhobo zokubethelela amaza

I-angle yothumelo lwezixhobo zokuthengisa amaza ngokuqhelekileyo zikhethwa phakathi kwe-5-8 degrees.Ichongwa ngummandla webhodi yesekethe eprintiweyo kunye nenani lamacandelo afakiweyo.

6. Uhlalutyo lokubunjwa kwe-tin kwindawo yokuhlambela i-soldering wave

Ukusetyenziswa kwe-solder kwindawo yokuhlambela ye-wave soldering isixhobo kuthiwa emva.Iya kwandisa ukungcola kwi-wave soldering lead solder, ngokukodwa ukungcola kwe-ion yobhedu echaphazela umgangatho we-welding.Ngokuqhelekileyo, kuthatha iinyanga ezi-3 uhlalutyo lwebhubhoratri - amaxesha.Ukuba ukungcola kungaphezulu komxholo ovumelekileyo, amanyathelo kufuneka athathwe endaweni yawo.
