Ngiyakuthanda ukudala okuqukethwe kwamahhala okugcwele izeluleko zabafundi bami, wena. Angilwamukeli uxhaso olukhokhelwayo, umbono wami owami, kepha uma uthola izincomo zami zilusizo futhi ugcina uthenga okuthile okuthandayo ngesinye sezixhumanisi zami, bengingathola ikhomishini ngaphandle kwezindleko ezengeziwe kuwe. Funda kabanzi
Ukulungiswa kwemithi kuhle kakhulu ukulungiswa kwaphakade. Kepha, nokho, ungasusa i-desolder ie remover solder usebenzisa ipompo elenzayo kanye nensimbi yoku-soldering. Kepha kuyakhohlisa uma ungenakho kwalokhu futhi udinga ukwenzeka ngokushesha okuphuthumayo.
Kulokhu okuthunyelwe sizomboza:
Usebenzisa i-Flat Head Screwdriver
I-screwdriver iyithuluzi elijwayeleke kakhulu elitholakala cishe kunoma iyiphi i-toolkit. Yize benzelwe ukujoyina, singabasebenzisela inhloso ephikisayo futhi. Ngokufanelekile, i-screwdriver yekhanda eyisicaba ingukukhetha kwendawo yayo enkulu yekhanda. Noma kunjalo, lezi zinyathelo ezimbalwa zinamandla okuholela kokunye okuhle.Isinyathelo 1: Hlikihla i-Tip
Bamba isikulufini sekhanda esicaba bese uhlikihla ikhanda laso ngendwangu yendwangu ehlanzekile neyomile. Lokho kuzoqinisekisa ukuthi akukho oxide noma ukugqwala okusalayo esigabeni sekhanda. Nansi ithiphu! Khetha i-screwdriver esidala kunawo wonke kuthuluzi lakho lamathuluzi. Njengoba i-screwdriver izofudunyezwa kakhulu futhi kamuva ipholile phansi, ijwayele ukuba nebala.
Isinyathelo 2: Ishise
Ngokushisa i-screwdriver, ithoshi le-propane yiyona ndlela engcono kakhulu. Ingadala ilangabi kuze kufike ku-2000 kuye kuma-2250 degrees Fahrenheit. Ngokungafani isibani se-butane esisetshenziselwa ukuhlanganisa amapayipi ethusi, ithoshi le-propane likhiqiza ilangabi elikhomba ngokwengeziwe. Bamba i-screwdriver ngqo elangabini le- isibani sokunamathisela ngomlilo bese ulinda ize insimbi iphenduke icishe ibe bomvu. Yenza lesi senzo njengesikhathi esiseduze ngangokunokwenzeka ku-soldering.
Isinyathelo 3: Ncibilikisa iSolder Phansi
Manje sesifikile isikhathi sokuthinta i-solder ngethiphu le-screwdriver esishisayo. Kepha udinga ukuqaphela kakhulu ukufaka ukushisa kuphela enhlanganisweni ye-solder oyifunayo, hhayi ezinye izingxenye zesifunda. Indawo ebanzi ngokuphelele ingumngane omuhle kakhulu walo msebenzi. Qiniseka ukuthi i-PCB ibekwe ngokulinganayo ngaphezulu. Bese uzama ukuthola inani eliphakeme le-solder noma i-bubble. Ukuthinta okulingene kwanele ukudala ukuxhumana okudingekayo phakathi kwethiphu le-screwdriver kanye ne-bubble. Kamuva cindezela ngobumnene uye phansi bese i-solder eqinile izoqala ukuncibilika.
Isinyathelo 4: Susa iSolder
Lapho usuqede ngempumelelo i-solder, udinga ukuyisusa kahle kwi-PCB. Futhi, i-screwdriver iyatakula! Bamba i-screwdriver okufanele siguqulwe kakhulu manje bese siyithinta nge-solder. Ngokushesha i-solder izonamathela ku-screwdriver. Ungasebenzisa enye i-screwdriver uma eyedlule ingeke ipholile ngokwanele.
Isinyathelo 5: Sula i-Tip
Phinda uthathe ithoshi le-propane ulishise. Bamba i-screwdriver elangabini. Bese uhlikihla ingubo ngendwangu. Ngakho-ke i-solder esele ebusweni be-screwdriver ingahlanzwa ngokufanayo indlela ohlanza ngayo i-iron soldering.
Okokulondolozwa Kwezinto Ezintekenteke Ezivela Kusekethe Yombane
Ungakwazi ngokuqinisekile susa i-solder kunoma iyiphi i-PCB ngaleyo ndlela eshiwo ngaphambili. Kepha kunezikhala ezithile. Lokho kushisa okufaka ebhodini kungalimaza ezinye izinto ezizwelayo kulelo bhodi. Kungakho kudingeka okuthile okungasusa ngokuphepha izingxenye. Noma kulezi zinqubo, ukushisa kuyadingeka. Kepha kusetshenziswa ezinye izindlela ukugcina ukulawula ukushisa nokuhlukanisa indawo ezungezile.
1. Ngokushisa iTheminali eyodwa
Akudingekile ukuthi ushise wonke ama-terminals ento ngasikhathi. Ungafaka ukushisa ngakunye. Le ndlela isebenza kangcono kakhulu lapho kufanele ubhekane nezinto eziyinkimbinkimbi. I-wattage yensimbi ephansi ingasetshenziselwa ukunikeza ukushisa. Ngaphandle kwalokho, ukufaka usinki wokushisa eduze kwento kungasebenza kakhulu ukususa ukushisa okungafuneki.
2. Usebenzisa i-Hot Air Gun ne-Suction Pump
Izibhamu zomoya ezishisayo zingashaya umoya oshubile ku-PCB futhi ekugcineni zingenza i-solder ishise ngokwanele. Ukusebenzisa isibhamu somoya oshisayo kuyindlela yobuchwepheshe yokuqedela umsebenzi. Kepha laba bantu bavame ukongeza ezinye izingxenye zensimbi kusekethe. Yingakho ukusebenzisa igesi le-nitrogen kuphephile. Yize la mathuluzi engashaya umoya oshisayo emajoyintini kodwa i-solder ekhiphela i-PCB ibidinga ukususwa. Iphampu yokudonsa edizayinelwe ngokukhethekile noma i-solder sucker iyadingeka ukukhipha ngokuphephile i-solder. Ukusebenzisa la mathuluzi kuzoqinisekisa ukuthi ayikho enye into ethintwayo noma akukho ukuvalwa okungafuneki kwe-solder okwenzekayo.
3.Ukusebenzisa amaphakheji we-Quad Flat ukususa izingxenye ezithile ezibucayi
Uma udinga ukusindisa i-IC kusuka ku-PCB, akunangqondo ukusebenzisa i-soldering iron ngqo. Vele, awukwazi ukushisa wonke ama-terminals aleyo IC ngasikhathi sinye ngensimbi yoku-soldering. Ngisho nokusebenzisa isibhamu somoya oshisayo ngokungenakulinganiswa akukwazi ukuletha umphumela oyifunayo. Kulesi simo, kufanele usebenzise iphakheji eyisicaba. Ukwakhiwa okuyisisekelo kwe-QFP kulula. Inemikhondo emincane ehlanganiswe eduze nezindonga ezine ezincanyana ezisebenza njengesivikelo sokushisa. Inesistimu yasentwasahlobo ebamba i-IC ibheke phezulu ngokushesha nje lapho i-solder ifinyelela esimweni soketshezi. Ngemuva kokumisa kahle i-QFP, udinga ukushaya umoya oshisayo kusuka kusibhamu somoya oshisayo. Njengoba ukushisa kubambeka endaweni oyifunayo yezindonga ezincane, i-solder kuleyo ndawo ithola ukushisa ngokushesha. Ngokushesha usukhululekile ukudonsa i-IC usebenzisa indlela yokukhipha. Enye i-QFC inezinsimbi ezengeziwe ezivikela ezinye izingxenye zesekethe ekuhlukanisweni.
Indlela Yamandla Okuhlukumeza
Uma ucabanga ukuthi i-PCB indala ngokwanele futhi ayisakwazi ukusebenzisa enye, ungasebenzisa inqubo ethile yamandla angenangqondo engakusiza ukuhlenga izingxenye. Bahlole!1. Sika amaTheminali
Ungasika ama-terminals wezinto ezingafuneki bese uzikhipha. Sebenzisa insingo ukwenza lo msebenzi. Ngaphandle kwalokho, i-vice-grip ingasiza kakhulu ekwephuleni isibopho se-solder futhi ikhiphe into. Kepha qaphela isandla sakho ngenkathi usebenzisa amandla. Kungcono ukugqoka amagilavu.
2. Thinta kanzima kunoma iyiphi i-Flat Surface
Lokhu kungabonakala njengokuhlekisa kepha ukuthepha ibhodi endaweni enzima kuyindlela yokugcina yokwephula ukuhlangana kwe-solder. Uma ungadingi ibhodi kepha izinto nje, ungaya ngale ndlela. Ukushaqeka okunamandla komthelela kungaphula i-solder futhi kubangele ukuthi ingxenye ikhululeke.
Umugqa Ongezansi
Okwamanje uyazi ukuthi ungasusa kanjani i-solder ngaphandle kwensimbi yoku-soldering. Akuyona nut enzima yokuqhekeka. Ngisho kwezinye izimo ukusebenzisa i-soldering iron akuphephile. Kepha khumbula noma iyiphi indlela oyithathayo, hlala uqinisekisa ukuthi usebenza endaweni eyisicaba futhi ungathinti i-solder encibilika ngesandla esingenalutho.
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
