Lisebelisoa tse hlokahalang bakeng sa kopano
Ka kopo netefatsa hore lisebelisoa tse latelang lia fumaneha:
- sekotla se senyane sa lehlakore
- tšepe e nyane ea solder e nang le ntlha e nyane
- thini ea solder (haeba ho khoneha 0.5mm bophara)
Litaelo tsa Tšireletseho
- Re etselitse lisebelisoa tsa rona bakeng sa tšebeliso ea ka tlung feela.
- Likarolo tsohle tsa motlakase le tsa elektroniki tse kenyellelitsoeng ka har'a khiti ena li tla sebelisoa ka matla a tlasetage feela ka ho sebelisa vol e lekiloeng le e amohetsoengtage transducer (transformer). Likarolo tsohle li na le maikutlo a mocheso. Nakong ea soldering mocheso o tla sebelisoa ka nako e khutšoanyane feela.
- Tšepe ea solder e hlahisa mocheso ho fihlela ho 400 ° C. Ka kopo, lula u ela hloko sesebelisoa sena. Boloka sebaka se lekaneng sa lintho tse tukang. Sebelisa pente e thibelang mocheso bakeng sa mosebetsi ona.
- Setsi sena se na le likaroloana tse nyane tse ka metsoang ho tsoa ho bana. Bana (haholo-holo ba ka tlase ho lilemo tse 3) ha baa lokela ho nka karolo kopanong ntle le bolaoli.
Tlhophiso
Bakeng sa boto-kopano ka kopo latela hantle tatellano ea lenane la kopano e ka tlase. Tlosa mola o mong le o mong joalo ka ha u qetile ho kenya le ho kopanya karolo e fapaneng.
Bakeng sa diode le Zener diode ka kopo boloka tlhokomelo e khethehileng ho polarity e nepahetseng (mohala o tšoailoeng bakeng sa cathode). The zener diode D4 e na le terata e teteaneng ea khokahanyo 'me e loketse boemo ba D4 feela.
Ka lebaka la mefuta e fapaneng ea li-capacitor tsa electrolytic u tla fumana matšoao a fapaneng a polarity. Tse ling li tšoailoe ka “+” ha tse ling li tšoailoe ka “-“. E 'ngoe le e' ngoe ea capacitor e tlameha ho bokelloa ho boto hore ho tšoaea ho capacitor ho ngollana le ho tšoaea pc-board.
Li-circuits tse kopaneng (IC`s) li tšoailoe ka notch ea halofo ea chitja ntlheng e le 'ngoe kapa ntlha e hatisitsoeng bakeng sa boemo bo nepahetseng ba ho hlongoa. Sututsa li-IC ka har'a sokete ho netefatsa hore notch kapa ntlha e tsamaisana le letšoao la kgutlotharo ho picobarn.
Ka kopo ela hloko kutloisiso ea IC`s ho discharge ea electrostatic e tla baka tšenyo ea hang-hang ea IC. Pele o ama likarolo tseo ka kopo, itokolle ka ho ikopanya le tšepe e entsoeng ka letsopa (mohlalaample radiator ea letsopa) kapa sebetsa ka letlapa la polokeho la electrostatic.
Ka kopo ela hloko letšoao "+" la li-rectifiers. Baetsi ba bang ba tšoaea likhokahano tsa "+" hape ka mohala o molelele oa khokahanyo. Haeba rectifier e bontša e le ho tšoaea lehlakore le bataletseng, lehlakore lena le tlameha ho lumellana le ho tšoaea ho pc-board.
Li-relay li tšoailoe ka mola o teteaneng ka lehlakoreng le leng. Mohala ona o tlameha ho lumellana le ho tšoaea ho pc-board.

Taelo ea soldering
Ha feela o se na boiphihlelo bo khethehileng ba ho soahla lisebelisoa tsa elektroniki ka kopo bala pele taelo ena ea ho soahla pele o qala mosebetsi. Soldering e tlameha ho koetlisoa!
- Le ka mohla u se ke ua sebelisa li-fluxes tse eketsehileng bakeng sa ho kopanya li-circuits tsa elektroniki tse nang le acid (mohlala, zinc chloride kapa ammonium chloride). Tseo li ka senya likarolo le li-circuits tse hatisitsoeng ha li sa hlatsuoe ka ho feletseng.
- Joalo ka thepa ea solder e lokela ho sebelisoa feela ka thini ea mahala ea solder e nang le mokokotlo oa rosin bakeng sa fluxing.
- Sebelisa tšepe e nyane ea solder e nang le matla a ho futhumatsa a 30 Watt. The solder tip e tla ba ntle ho sekala ho netefatsa phetiso e ntle ea mocheso sebakeng se lokelang ho rekisoa.
- The soldering e tla etsoa ka potlako hobane mocheso o telele o ka senya likarolo. Ho futhumatsa haholo kapa nako e telele ho ka tlosa liphaephe tsa koporo le lipina tsa koporo ho tloha boto.
- Bakeng sa solder e ntle, ntlha ea solder e kentsoeng hantle e tlameha ho kopanngoa le terata ea koporo le terata ea motsoako ka nako e le 'ngoe. Ka nako e le 'ngoe ho tla sebelisoa solder-tin bakeng sa ho futhumatsa. Hang ha solder-tin e qala ho qhibiliha terata ea tin e tlameha ho tlosoa.
Emela feela ho fihlela thini e kolobisitse pete hantle le terata ebe o tlosa tšepe ea solder ho tloha sebakeng sa solder. - Etsa bonnete ba hore u se ke ua sisinya karolo e sa tsoa rekisoa ka metsotsoana e ka bang 5 ka mor'a ho tlosa tšepe ea soldering. Sena se lokela ho theha motsoako oa silevera o khanyang o se nang molato.
- Bakeng sa motsoako o se nang molato le solder e entsoeng hantle ke ntlha e hloekileng e senang oxidized soldering-tip e hlokahalang ka ho feletseng. Ho ke ke ha khoneha ho etsa motsoako o lekaneng oa soldering ka ntlha e litšila ea solder.

- Ka mor'a hore ho phethoe, lithapo tsohle tsa ho kopanya li tlameha ho tlosoa ka holim'a lenonyeletso ka ho sebelisa seha se lehlakoreng.
- Ka soldering semiconductors (transistors, diodes), LED`s le IC`s ke habohlokoa haholo hore le ka mohla ho se fete nako ea soldering ea metsotsoana e 5 ho thibela timetso ea karolo. Hoa hlokahala ho ela hloko polarity e nepahetseng ea karolo pele o qala ts'ebetso ea soldering.
- Ka mor'a seboka sa boto laola ka hloko pc-board mabapi le ho kenngoa ka mokhoa o nepahetseng ha likarolo le polarity e nepahetseng. Ka kopo, hlahloba hore na ha ho na likhokahano kapa lipina tsa koporo tse khutsufalitsoeng ka thini ea solder. Sena se ke ke sa fella feela ka ho se sebetse hantle ha mojule empa hape se baka tšenyo ea likarolo tse theko e boima.
- Ka kopo, ela hloko hore li-solder tse sa nepahalang, likhokahano tse fosahetseng, ts'ebetso e fosahetseng kapa kopano e fosahetseng ea boto ha se taba e ka har'a maemo a rona a tšusumetso.
Boitsebiso bo akaretsang ba ho kenya
Lithapo tsa li-resistors le diode tse tla bokelloa sebakeng sa leshano li tla koaheloa ho latela sebaka sa raster sebakeng se nepahetseng sa angular ebe se bokelloa ka har'a libore tse boletsoeng (ho latela moralo oa kopano ea boto kapa matšoao a kopano). E le ho thibela hore likarolo li se ke tsa oa ka ho fetola pc-board ka kopo, koba lithapo tsa ho hokahanya hoo e ka bang 45 ° ka thōko ebe u li rekisa ka hloko ho liphahlo tsa koporo ka lehlakoreng le ka morao la boto. Qetellong lithapo tse feteletseng li tla khaoloa ka sehahi se senyenyane sa lehlakore.
Li-resistant tse ka har'a li-kits tse fanoeng ke li-resistors tsa tšepe-foil. Ba na le mamello ea 1% 'me ba tšoauoa ka "tolerance-ring" e sootho. Reng ea mamello e ka tsejoa ka sebaka se seholo sa moeli ka ho latellana sebaka se seholo ho ea ho tse ling tse 'nè tse tšoaeang. Ka tloaelo ho na le mehele e mehlano ea mebala holim'a li-resistors tsa tšepe-foil. Ho bala khoutu ea 'mala u tlameha ho fumana mohanyetsi ka tsela eo selikalikoe sa mamello se sootho se tla ba ka lehlakoreng le letona. Mehele ea mebala e tla ba khubelu hona joale ho tloha ho le letšehali ho ea ho le letona!
Ka kopo hlokomela ho kopanya diode ka polarity e nepahetseng (boemo ba letšoao la cathode). Hlokomela ka nako e khuts'oane haholo ea solder! Ho tla sebetsa se tšoanang ho li-transistors le li-circuits tse kopaneng (IC`s). Lehlakore le bataletseng la li-transistors le tlameha ho lumellana le ho tšoaea leboteng la pc.
Maoto a transistor ha aa lokela ho bokelloa sebakeng se tšetsoeng.
Ho feta moo likarolo tseo li lokela ho ba le sebaka se ka bang 5mm ho ea boto. Etela nako e khutšoanyane ea soldering ho thibela tšenyo ea karolo ka mocheso o feteletseng.
Li-capacitor li tla bokelloa ka har'a libore tse tšoailoeng, lithapo li tla kobeha hanyane ebe li rekisoa ka hloko ho pente ea koporo. Ka kopano ea electrolytic capacitors (electrolytic cap) e tlameha ho ba teng ho polarity e nepahetseng (+,-)! Li-capacitor tsa electrolytic tse rekisoang ka tsela e fosahetseng li ka phatloha nakong ea kopo! Ka hona ho bohlokoa haholo ho hlahloba polarity e nepahetseng habeli kapa ho feta makhetlo a mararo. Ho feta moo, e tlameha ho hlokomeloa ho litekanyetso tse nepahetseng tsa capacitor, mohlala, n10 = 100pF (eseng 10nF!).
