1. Litlhoko tsa mantlha tsa ts'ebetso ea SMT bakeng sa moralo oa likarolo ke tse latelang:
Kabo ea likarolo ho boto ea potoloho e hatisitsoeng e lokela ho ba e ts'oanang ka hohle kamoo ho ka khonehang.Bokhoni ba mocheso oa reflow soldering ea likarolo tse kholo tsa boleng bo boholo, 'me mahloriso a feteletseng a bonolo ho baka mocheso o tlase oa lehae mme o lebisa ho solder ea sebele.Ka nako e ts'oanang, sebopeho sa junifomo se boetse se loketse ho leka-lekanya bohareng ba matla a khoheli.Litekong tsa vibrate le tšusumetso, ha ho bonolo ho senya likarolo, likoti tse entsoeng ka tšepe le lipampiri tsa solder.
2. Tataiso ea ho tsamaisana ha likarolo ho boto ea potoloho e hatisitsoeng e lokela ho tšoana ka hohle kamoo ho ka khonehang bakeng sa likarolo tse tšoanang, 'me tataiso ea sebopeho e lokela ho tšoana le ho thusa ho kenya, ho tjheseletsa le ho lemoha likarolo.Haeba electrolytic capacitor positive pole, diode positive pole, transistor single pin end, pini ea pele ea tataiso e kopanetsoeng ea potoloho ea potoloho e lumellana ka hohle kamoo ho ka khonehang.Tataiso ea khatiso ea linomoro tsohle tsa likarolo e tšoana.
3. Likarolo tse kholo li lokela ho siuoa ho pota-potile SMD rework thepa futhumatsang hlooho e ka sebetsoa boholo.
4. Likarolo tse futhumatsang li lokela ho ba hōle le likarolo tse ling ka hohle kamoo ho ka khonehang, ka kakaretso li behiloe sekhutlong, lebokose la boemo ba moea.Likarolo tsa ho futhumatsa li lokela ho tšehetsoa ke lisebelisoa tse ling kapa litšehetso tse ling (tse kang mocheso oa mocheso) ho boloka sebaka se itseng pakeng tsa lisebelisoa tsa ho futhumatsa le holim'a boto ea potoloho e hatisitsoeng, ka bonyane ba sebaka sa 2mm.Likarolo tse futhumatsang li kopanya likarolo tsa ho futhumatsa le mapolanka a potoloho a hatisitsoeng ka mapolanka a mangata.Ka ho qaptjoa, lisebelisoa tsa tšepe tsa tšepe li etsoa, 'me ha li sebetsa, solder e sebelisoa ho li kopanya, e le hore mocheso o tsoe ka mapolanka a potoloho a hatisitsoeng.
5. Likarolo tse thibelang mocheso li lokela ho bolokoa hole le likarolo tse hlahisang mocheso.Tse kang li-audions, li-circuits tse kopantsoeng, li-capacitor tsa electrolytic le likarolo tse ling tsa polasetiki, li lokela ho ba hole le borokho ba borokho, likarolo tsa matla a phahameng, li-radiator le li-resistors tse matla haholo.
6. Sebopeho sa likarolo le likarolo tse hlokang ho lokisoa kapa hangata ho nkeloa sebaka, joalo ka potentiometers, li-coil inductance tse feto-fetohang, li-micro-switches tse feto-fetohang, li-tubes tsa inshorense, linotlolo, li-plug le likarolo tse ling, li lokela ho nahana ka litlhoko tsa sebopeho sa mochini kaofela. , 'me u li behe sebakeng seo ho leng bonolo ho se fetola le ho se nkela sebaka.Haeba mochine o lokisa, o lokela ho behoa boto ea potoloho e hatisitsoeng ho thusa ho lokisoa ha sebaka;Haeba e lokisoa ka ntle ho mochine, boemo ba eona bo lokela ho ikamahanya le boemo ba knob ea ho lokisa holim'a phanele ea chassis ho thibela khohlano pakeng tsa sebaka sa mahlakore a mararo le sebaka sa mahlakore a mabeli.Mohlala, ho buloa ha konopo ea konopo ea konopo ho lokela ho ts'oana le boemo ba sekheo sa switch ho boto ea potoloho e hatisitsoeng.
7. Sekoti se tsitsitseng se lokela ho behoa haufi le terminal, plug le ho hula likarolo, karolo e bohareng ea terminal e telele le karolo eo hangata e etsoang ka matla, 'me sebaka se lumellanang se lokela ho siuoa ho pota-pota lesoba le tsitsitseng ho thibela ho senyeha ka lebaka la katoloso ya mocheso.Joalo ka katoloso ea nako e telele ea mocheso oa mocheso e tebile ho feta boto ea potoloho e hatisitsoeng, maqhubu a solder a atisang ho ba le ketsahalo ea warping.
8. Bakeng sa likarolo tse ling le likarolo (tse kang li-transformer, li-electrolytic capacitors, varistors, mekotla ea borokho, li-radiator, joalo-joalo) ka mamello e kholo le ho nepahala ho fokolang, nako e pakeng tsa bona le likarolo tse ling e lokela ho eketseha ka moeli o itseng motheong oa maemo a pele.
9. Ho kgothaletswa hore karolo e ntseng e eketseha ea li-electrolytic capacitors, varistors, mekotla ea borokho, li-capacitor tsa polyester le li-capacitor tse ling e se ke ea e-ba ka tlase ho 1mm, le ea li-transformer, li-radiator le li-resistors tse fetang 5W (ho kenyeletsoa 5W) ha lia lokela ho ba ka tlase ho 3mm.
10. The electrolytic capacitor ha ea lokela ho ama likarolo tsa ho futhumatsa, tse kang li-resistors tse matla a matla, li-thermistors, li-transformer, li-radiator, joalo-joalo Nako e pakeng tsa electrolytic capacitor le radiator e lokela ho ba bonyane ba 10mm, le karohano pakeng tsa likarolo tse ling. radiator e lokela ho ba bonyane 20 mm.
