Isiteshi esithinta ngesandla

Ngesikhathi sokulungiswa kwe-microcircuits, i-motherboard yekhompiyutha kuyadingeka ukusebenzisa insimbi yokuxubha. Kodwa akuzona ngaso sonke isikhathi esivumelwaneni ukusebenzisa, ngoba ishesha kakhulu, akunakwenzeka ukulawula ukushisa. Futhi-ke kuyadingeka isiteshi esithuthukisiwe esisezingeni eliphezulu. Ngezandla zakhe siqu wafunda ukudala abadwebi bomuntu.

Okukhethwa kukho ukudala isiteshi se-soldering, esibekwe endaweni yokuhlinzeka ngamandla (ngokuqondile, umzimba wayo) kusuka ensimbi yokuxubha, amashumi ayisishiyagalombili nanhlanu ngamamitha angamashumi amahlanu nanhlanu kuya kwamashumi ayisithupha nanhlanu, kanti kungenzeka ukuthi ixhuma i-EPSN endala. Ukwakha isiteshi se-soldering, udinga ukuthenga i-soldering iron ene-resertive nge-heater, i-sensor yokuvuselela kanye ne-tip 1.6 emithamitha efana ne-wedge.

I-thermocouple evela kumkhiqizo we-multimeter we-Chinese yakhiwe ku-EPSN. Ibhodi elilawulayo lithole amashumi amane nantathu ngamamitha ayizinkulungwane ezingamashumi amathathu nantathu. Isiteshi esineziphathekayo se- digital , esihlangene ngesandla, sizisa ukuthi silungele umsebenzi wezinsimbi zokudonsa ngemibhalo ebhalwe phansi. Ngemuva kokuqalisa, isilawuli siphenduka UMTHETHO futhi sifunda izinga lezintambo emibhalweni ye-PC0, i-PC1. Uma kwenzeka ukuthi ilingana ne-voltage supply, khona-ke azikho izinsimbi ze-soldering, futhi ukubonisa kubonisa "Iphutha" elibonisa iphutha.

Lapho umthamo kwenye yezinzuzo ungaphansi kuka-4.5 Volts, ungakhetha insimbi yokuxubha noma i-resistive noma i-thermocouple. Futhi wonke umuntu ungasebenzisa izihluthulelo zokulungisa ukushisa. Iphashazi elikhanyayo livela esibukweni ukubonisa ukuthi iyiphi idivayisi ekhethiwe. Amandla we-soldering iron angalawulwa ukuguqulwa kwe-PWM nekhi ye-VT1.

Lapho isiteshi se-soldering sihlangene ngezandla zakho, ungenza ngaphandle kwezinguquko ezengeziwe, ngoba nge-2 mA yamanje, ukukhanya okunamandla nokukhanyayo kuzotholakala. Ama-cathodes axhunyiwe ngokuqondile emachwebeni omlawuli. I-indicator kumele ifakwe ibhodlela ebhodini enezintambo ezincane futhi ihlelwe ngemuva kwe-adhesive-melt adhesive.

Ukuze ufake izinkinobho kanye nokubonisa, kubalulekile ukwenza izimbobo ku-panel yangaphambili yecala. Dweba iphaneli esibukweni sokubukwa kwesithombe esibukweni, faka i-tape emhlophe emaceleni omabili eceleni kwe-toner, unqume umjikelezo wephethini bese unamathisela emzimbeni. Ukuze kube lula inkinobho, kungcono ukufaka i-panel iphaneli usebenzisa umshini wokubamba okushisa.

Ukuze usebenze ukufaka ngamabhodi amakhulu, njengebhodi le-motherboard lamakhompiyutha noma ama-laptops, isiteshi se- infrared soldering sifanelekile , kungenzeka ukuba wenze ngokwakho. Ukuze uthole ukuxubha, lapho ukuphakama komzimba kwe- PCB kanye nezingxenye zayo (isib. BGA) kufakwe, umoya oshisayo noma imisebe ye-infrared kufanelekile.

Idivayisi ngokwayo iqukethe iyunithi yokulawula ezindlini ezihlukene. Inama-heaters amabili nezintaba zebhodi. Isikhundla esiphakeme singashintshwa kuye ngokuthi ibhodi ehleliwe. Umshini wokushisa ophansi ungumshini wezitofu zikagesi ezinamandla amabili kilowatts kanye nobubanzi bamamitha ayizinkulungwane amabili namashumi amabili. I-heater engenhla yizibani ezine ze-halogen ezine-tubular. Ngamunye wabo - 150 watts ngamunye. Ngakho-ke, isiteshi se-soldering, esihlangene ngezandla zayo, sibheke ngokuphelele.

I-tripod ingenziwa kusuka kuma-racks ukusuka kumphrinta we-dot matrix. Yonke imininingwane ibuye ibolekwe ubuchwepheshe bekhompyutha yakudala. I-indicator iyi-liquid line crystal module kanye nomlawuli. Esikhundleni se-pulse transformers, kungcono ukusebenzisa ama-core core kanye nama-radiators awo. Kumele kukhunjulwe ukuthi ukuqapha kuyadingeka lapho ufaka, ngoba izintambo eziyisikhombisa ziphila. Ngaphezu kwalezi zingxenye ezidingekayo, iyunithi yokunikezwa kwamandla iyadingeka esiteshini se-soldering, ihlinzeka ngamanje ngeziteshi ezimbili, ikhibhodi, isibonisi, i-alamu ezwakalayo kanye nomtshina we-zero.

Uma usungule isiteshi se-soldering ngezandla zakho, kubalulekile ukwazi neminye imithetho yokuphepha uma usebenza nayo. Isibonelo, akufanele uvumele izibani ze-halogen ukuthi zenziwe ngamafutha. Ngakho-ke, kumele basulwe ngokuphelele nge-acetone noma i-petroli, futhi bagqoke izinkuni ezivikelayo kusukela elangeni ngaphambi kokuqala umsebenzi.
