Solder rosin: ezinye iimfihlelo ngelotha

engahlawulwayo nganye unomathotholo okanye inkosi, ezijongene ukulungiswa ngokwakho, kungekudala emva koko, kuya kufuneka ukuba sithathe i zentsimbi ngelotha kunye itrayi. Umgangatho komsebenzi, kwaye nkqu yokusebenza iimveliso ziya kuxhomekeka ngqo kwizinto ezininzi, ezo bazi ukuba kufuneka uqiniseke phambi kokuba baqalise umsebenzi.

umsebenzi umlungise ngentsimbi ngelotha

Nangona elula emananga nomsebenzi intsimbi ngelotha, kungakuhle kakhulu ukuba i engundoqo umsebenzi osemgangathweni izakhono kwaye akwazi ukusebenzisa kakuhle solder ne rosin.

Ngelotha lwenziwa kusetyenziswa iintlobo ngeentlobo solders. I-ekuthiwa solder Ikhoyili kunye rosin, mhlawumbi othandwa kakhulu. Xa usenza umsebenzi ezinxulumene ngelotha, kusetyenziswa solder. Inani yokukhokela equkethwe nebhekile - 60 no-40%, ngokulandelelana. Le ingxubevange linyibilike kwi 180 c.

Kufuneka sisebenze ngentsimbi ngelotha:

• intsimbi ngelotha ngokwayo;
• solder;
• rosin.

Le solder eshushu idala zokuqhagamshelwa ezaneleyo kunye nesinyithi ezifana nobhedu, nobhedu, nesilivere, njalo njalo, ukuba iimeko ilandelayo ..:

• Evele amalungu kufuneka icocwe of oxides.
• Iinkcukacha le ndawo eshushu ngelotha lobushushu yokunyibilika eyomeleleyo solder.
• Ngexesha lo msebenzi ngelotha kufuneka ukukhusela kwimiphumo oksijini, kwiintlobo ngeentlobo fluxes zisetyenziswa. Zakha zokhuselo umboniso ngqo ngaphezulu ndawo ngelotha.

Incwadi ukuba solder njani, unako ukufunda nokuqonda, kodwa izakhono ngelotha zingafumaneka kuphela practice.

Amaqhinga kunye ezifihlakeleyo yokusebenza ngentsimbi ngelotha

Emva kokuba solder zaqalisa ukunyibilika, sele kunokwenzeka ukuba solder. Kuba oku kuyimfuneko yokugubungela ngelotha kwincam netolstym solder ezikroziswayo koko kakuhle koma oko isiponji emanzi. Ngoko ke susa okuseleyo umsebenzi solder kunye rosin. Uyacetyiswa ukuba ukungena umkhwa bezihlikihla ahlatywe isiponji emanzi emva ngelotha nganye.

Ngaphambi kokuba uqale solder amacandelo irediyo, kuyimfuneko ukuba Isilungiselelo. Kufuneka aguqe izigqibo zayo ukuze inxalenye ikhululekile ukungena umngxuma elungiselelwe oko.

Afikayo ngaphandle ngamava badla kuzixhalabisa incam ngelotha ngayo kwincam ngelotha. A imfuneko ukugcina intsimbi ngelotha kangangokuba phakathi kwakhe kunye nendawo ngelotha ummandla zoqhagamshelwano ibenkulu kangangoko kunokwenzeka, okanye enye indawo apho ukuvelisa solder itshiswa ngokwaneleyo ukuze basondelelane iindawo.

Indlela ekucoceni kwincam ngelotha

Xa ngelotha ngelotha intsimbi rhoqo ivela Nagar. It kungaba zisuswe ngamanzi ethafeni. Ukuba uphethe intsimbi ngelotha kwi ngelaphu elifumileyo, ngoko ke isikali liya kuba phezu kwalo, yaye ulwamvila kwakhona abe uhlambulukile. Ngamaxesha athile, kufuneka oku kwenziwa xa usebenza ngentsimbi ngelotha. Ukuba laphu swi nga pfuna, ungasebenzisa isiponji nzima.

ngelotha Iiklasi tip

• abasusekayo ngelotha kunye nickel ngeso lenyama.
• I lel copper.

incam ngelotha kwiklasi yokuqala izinto ezisetyenziswa solders oluxandileyo, bayakwazi izinga.

Ahlatywe sesibini - yeyona ixhaphakileyo.

Iindidi ngumfanekiswana ngelotha tip

• Ulwamvila ngokwemo neenaliti - ukuba amacandelo solder nonomathotholo omncinci kakhulu ezifana SMD. Ekuphunyezweni ukulungisa buyafuneka ulwamvila phones. Usetyenziswa iiplanga ezixineneyo ungamalungu imvelaphi inyuselwa khona.
• Imiphumela-spatula - sisetyenziselwe ukunkcankcashela kwaye kwimeko ufakelo amacandelo ezinkulu elektroniki. basebenza kunye multi-phambili chip.
• Ulwamvila ngokwemo ngamathontsi - iluncedo ukuthwala solder kunye rosin ukuya kwindawo ngelotha, ebangela ezikumgangatho ophezulu lomsebenzi.
• Imiphumela nge ifomu egosogoso - kaninzi ke desoldering ibekwe iqokobhe obhedu kwibhodi radio ayizange ihlale i solder engaphezulu. Kananjalo zisetyenziswe ngelotha eziqhelekileyo. A intsimbi ngelotha lashushu lobushushu ka 290-300 C.

Ngokusebenza kunye ngentsimbi ngelotha, kufuneka usoloko uyigcine ukucoceka egqibeleleyo. Kwincam ngelotha amatsha ngokuqhelekileyo iphathwa ngehamile ukuya kumphezulu wayo kwasekwa nameva ezincinane. Kamva, abo kakuhle zalungisa kanye kwifayile ukunika ifomu echanekileyo ulwamvila.

Ngoko ke Ulwamvila kufuneka zaludit usebenzisa solder ne rosin. Oko kukuthi, umaleko obhityileyo solder kuditshwa ibe nentlaka.

Kanjani cool indawo ngelotha

Forceps ngesinyithi, enamathela amacandelo radio, kwaye isebenza njenge isinki ubushushu ngexesha ngelotha. Ungasebenzisa le njongo yaye kwesibambi "ingwenya" okhethekileyo.

Amahlebo ngelotha ngelotha intsimbi

Ukuze ufumane nemiphumo emihle xa kufuneka ngelotha ukusebenzisa kakuhle solder kunye rosin ligazi ukumpompoza. Le elisezantsi-ukunyibilikisa ingxubevange metal ezizodwa, apho solder ezinjengeetheminali nxalenye iingcingo.

• Best solder - tin ingohlobo olunyulu. Kodwa olu ibiza kakhulu ukuba ukusebenzisa ngexesha ngelotha. Ngoko ke, xa besebenza kunye namacandelo radio le zisetyenziswa ekuthiwa-solders abakhokelayo-tin.
• Ukukhokela nensimbi. Ngomhla ngamandla ezi solders brazing ngaphezu etotini ecocekileyo. Bona kunyibilike kwiqondo lobushushu degrees 170-190. Ukubonisa ezinjalo solders shunqulelo "POS" - nebhekile-lead solder. Standing emva kwezi oonobumba nesikhundla mzobo kuthetha umyinge tin, wavakalisa njengepesenti. Kungcono usebenzise solder "POS-6D".

• Fluxes - ezi zizinto leyo ilifa iipropati antioxidant. Zisetyenziswa ukuthintela igcwala namalungu solder. Ukuba awufuni ukusebenzisa nobhobhozayo, lo solder akuthethi nje anamathele kumphezulu sentsimbi.

iintlobo obhobhozayo ekubhobhozeni

Xa sisebenza kunye namacandelo radio kusetyenziswa fluxes ezo ayiqulathanga acid. Ngokomzekelo, rosin. Le igcina zithengiselwa uyithobele rosin ukuthambisa ajikeleze izixhobo zomculo. Kusenokuba kuhle zisetyenziswe ngelotha. Kodwa izinto metal soldered kusetyenziswa solder rosin-free. Kuba ukulungisa yawo efunekayo "kwakhona acid". Oku unyityilikiswa zehydrochloric acid kunye zinc. ngelotha Electronic ne solder ngokunjalo akunakwenzeka, kuba ekugqibeleni iya kutshabalalisa brazing.

Ukuba ufuna ukwenza solder kwiindawo azifikeleleki, kuyimfuneko ukuba wampompoza ulwelo. kungaya ngokuzimeleyo. Rosin Utyunyuziwe wayicola yangumgubo, oko igalelwe acetone okanye ethyl utywala. Isisombululo yawavuselelayo kufuneka ugalele rosin ngaphezulu de pasty mass zamafu. Endaweni yokuba ngelotha a intlaka ulwelo ukuba ayisetyenziswa ibrashi okanye ngentonga. Kulo mzekelo, kukho ezincinane - ukuhlolwa of iibhodi beesekethe eprintiweyo nangawe kufuneka amanzi. Kuba nzima ukufikelela iindawo, unako ukusebenzisa ucingo solder kunye rosin, kananjalo kube lula kakhulu ngakumbi.

Xa sisebenza kunye fluxes ezahlukeneyo kufuneka iqwalaselwe ukuba abo benziwa acetone, - ayityhefu kakhulu. Ngoko ke, sisebenza nabo ukuthintela inhalation umphunga. Plumbing engcono kufuphi i window, ukuba ihlobo, yaye ebusika badla pholisa igumbi apho umsebenzi luyenziwa. Xa sele ugqibile qiniseka ukuba uhlambe izandla zakho ngesepha namanzi ashushu.

Indlela solder solder ne rosin

Yimeko ebalulekileyo ngelotha yimpumelelo kunye ukucoceka imiphezulu ekufuneka ukuba solder. Qiniseka ukuba solder amalungu esihlambulukileyo kukhanya. iinkcukacha ke kufuneka ubeke phezu kwiphetshana rosin ifudumele. Le rosin solder otyhidiweyo uya ngokulinganayo ngaphezulu i guidewire okanye iinkcukacha ofuna solder. Kuyenzeka ukutshintsha ngokuchanekileyo umba, ukubaleka kulo nentsimbi ngelotha ukuya solder ahlayo ukuthwalisana komhlaba.

Ukuba kuyimfuneko umqhubi zaludit leyo soldered kwibhodi, emva bamhluba indawo ngelotha kunye sandpaper okanye imela kuyimfuneko ukuba ndithabathe iqhekeza rosin, uze solder kamnandi babele kangangoko ngokulinganayo kangangoko kunokwenzeka, ukuchitha ngelotha.

Xa umgangatho ngelotha linayo yaye enxulumene nendlela kakuhle iingcingo ngelotha okanye abafowunelwa neenkcukacha. Kufuneka ambathe ohlohliweyo kunye, kwaye balungiselela ukuba izinikezeli ngelotha inhliziyo. Emva kokuba solder eshushu iya kusasazwa phezu komhlaba, Gulf of nkqu izikhewu ezincinane phakathi kwabo, i yentsimbi ngelotha kufuneka isuswe.

ixesha ngelotha eqhubekayo kufuneka ungabi ngaphezu kwemizuzwana emihlanu. Emva kweli xesha, le Ukuguqulwa kolwelo solder kwaye iinkcukacha ziza kumiselwa ngokuqinileyo yesondo. Nakuba kunjalo, ukwenzela ukuba atshabalalise ngelotha, izahlulo lingashukumi kwimizuzwana 10-15 emva ngelotha ukuvalwa. Kungenjalo, ukuxhumeka ezingazinzanga.

Ukuba usebenza transistors, iziphumo zabo kufuneka zikhuselwe ukuthintela nobushushu. Kulungile ukugcina okanye iplayasi okanye amashiya, ukwenza oku ukusasaza ubushushu.

Xa ngelotha lwamacandelo yekhompyutha kuyo nayiphi na imeko akukho mfuneko bajije iziphelo iinxalenye. Ukuba ufuna solder izahlulo okanye endaweni abaqhubi, kuyimfuneko ukuba bacinge kwangaphambili ngayo ngaphambi kokufakwa. Iziphelo iinxalenye ngelotha ichanileyo kumgama encinane enye kwenye, kunokuba kwindawo enye.
