Solder rosin: ena zinsinsi soldering

Aliyense ankachita masewera wailesi kapena mbuye amakamba kukonza nokha, posapita nthawi, adzakhala ndi kukatenga chitsulo soldering ndipo tiyese. Quality wa ntchito, ndipo ngakhale ntchito mankhwala utsogoleri zimadalira zinthu zambiri, amene akudziwa kufunika kukhala otsimikizika asanayambe ntchito.

Kukhoza ntchito ndi chitsulo soldering

Ngakhale kuphweka n'zopanda ntchito ndi soldering chitsulo, ndi zofunika kwambiri kukhala zofunika luso khalidwe ntchito ndi kuzigwiritsira ntchito bwino solder ndi rosin.

Soldering imagwiridwa ntchito zosiyanasiyana solders. Otchedwa solder ndi koyilo ndi rosin, mwina wotchuka kwambiri. Pamene kugwira ntchito kugwirizana ndi soldering, solder ntchito. Chiwerengero cha kutsogolera zili ndi malata - 60 ndi 40%, motero. aloyi Izi chimasungunula pa 180 c.

Muyenera ntchito ndi chitsulo soldering:

• soldering chitsulo;
• solder;
• rosin.

The solder mkangano amalenga interconnection okwanira ndi zitsulo monga mkuwa, mkuwa, siliva, etc., ngati zinthu zotsatirazi ..:

• Kali mbali ayenera kutsukidwa wa oxides.
• Tsatanetsatane wa malo mkangano soldering mphamvu limatsogolera kutentha kwa solder lapansi.
• Pa ntchito soldering chofunika kuteteza chifukwa cha mpweya, chifukwa zosiyanasiyana fluxes ntchito. Kulenga filimu zoteteza mwachindunji pamwamba pamalo soldering.

Buku mmene solder, mukhoza kuwerenga ndi kumvetsetsa, koma luso soldering akhoza zopezera ntchito.

Zidule ndi zinsinsi za ntchito ndi chitsulo soldering

Pambuyo solder anayamba kusungunuka, ndi kale zotheka kuti solder. Pakuti ichi m'pofunika kuphimba soldering nsonga netolstym solder wosanjikiza kenako bwino ziume pa chinkhupule chonyowa. Choncho chotsa yotsala ya ntchito ya solder ndi rosin. Iwo m'pofunika kuti ndi chizolowezi akusisita mbola ya chinkhupule chonyowa nthawi iliyonse soldering.

Musanayambe solder zigawo wailesi, m'pofunika kukonzekera. Iwo lipinde mfundo zake kotero kuti mbali ndi ufulu kulowa dzenje anafuna izo.

Atsopano popanda zinachitikira zambiri nkhawa soldering kunsonga ya soldering kwenikweni. A tiyenera kukhala chitsulo soldering kotero kuti pakati pa iye ndi malo soldering m'dera kukhudzana lalikulu monga zotheka, kapena aliyense pamalo amene kubala solder ndi mkangano zokwanira kukondana kwambiri mbali.

Kodi kuyeretsa soldering nsonga

Pamene soldering soldering chitsulo umatchulidwatchulidwa Nagar. Iwo akhoza kuchotsedwa ndi madzi opanda. Ngati mukhala chitsulo soldering pa nsalu yonyowa pokonza, ndiye lonse lidzakhala pa izo, ndipo mbola amakhalanso oyera. Nthawi muyenera ichi chidachitika pamene tikugwira ntchito ndi chitsulo soldering. Ngati nsalu si kuthandiza, mungagwiritse ntchito chinkhupule zovuta.

Makalasi soldering nsonga

• Soldering zochotseka ndi ❖ kuyanika faifi tambala.
• Ine kuluma mkuwa.

Soldering nsonga ya kalasi loyamba amagwiritsidwa ntchito mu solders zovuta zomwe angathe zonse kutentha.

Mbola ya wachiwiri - ambiri.

Mitundu yokutidwa soldering nsonga

• Mbola mu mawonekedwe a masingano - iwo ali ochepa zigawo solder wailesi monga SMD. Mu kukhazikitsa kukonzedwa ndi yofunika mafoni mbola. Izo ntchito pa matabwa ndi osalimba mkulu mbali wokwera.
• Mbola-spatula - ntchito kuthirira Tikanena unsembe wa zigawo zikuluzikulu amagetsi. Akugwira ntchito ndi Chip Mipikisano patsogolo.
• Mbola mu mawonekedwe a madontho - zili kunyamula solder ndi rosin kumalo soldering, chifukwa mu apamwamba khalidwe la ntchito.
• Mbola ndi mawonekedwe yokhota kumapeto - zambiri iwo desoldering wailesi ili chipolopolo zamkuwa bolodi sanakhalemo solder owonjezera. Angagwiritsidwenso ntchito soldering ochiritsira. A chitsulo soldering usavutike kutentha 290-300 C.

Pogwira ntchito ndi chitsulo soldering, muyenera nthawi zonse mu ukhondo wangwiro. The watsopano soldering nsonga nthawi ankachitira ndi nyundo pamwamba ake anapanga barbs yaing'ono. Zotsatira zawo mwabwino nakonza ndi wapamwamba kupereka mawonekedwe bwino za ululu.

Ndiye mbola ayenera zaludit ntchito solder ndi rosin. Ndiye kuti, ndi wosanjikiza zonyalazo solder akusunsa mu utomoni a.

Kodi ozizira pa soldering malo

Forceps zitsulo, amene amatsatira zigawo wailesi, ndipo komabe ukugwira ntchito ngati koziziritsira pa soldering. Mukhoza kugwiritsa ntchito Mwaichi ndi wapadera achepetsa "ng'ona."

Zinsinsi soldering soldering chitsulo

Kuti mupeze zotsatira zabwino pamene soldering chofunika kuti bwino ntchito solder ndi rosin ndi kamwazi. Ichi ndi wapadera otsika-kusungunuka zitsulo aloyi, amene solder malo mbali ndi mawaya.

• Best solder - malata ndi mu maonekedwe woyera. Koma zitsulo izi mtengo kwambiri ntchito pa soldering. Choncho, pamene tikugwira ntchito ndi zigawo wailesi ntchito otchedwa solders kutsogolera-lata.
• Tsogolerani ndi malata. Pa mphamvu ya solders izi brazing kuposa malata koyera. Iwo anasungunuka pa kutentha madigiri 170-190. Potanthauza ngati solders chidule "POS" - malata-kutsogolera solder. Atayima pambuyo makalata amenewa zoti chithunzi kumatanthauza chiwerengero cha malata, anasonyeza kuti anthu a. Ndi bwino ntchito solder "POS-6D".

• Fluxes - ndi zinthu zomwe adzalandira antioxidant katundu. Iwo ntchito popewa makutidwe ndi okosijeni zimfundo ndi solder. Ngati mulibe ntchito kamwazi, ndi solder sumangopita n'kudziphatika pamwamba pa zitsulo.

mitundu ya kamwazi

Pamene ntchito ndi zigawo wailesi ntchito fluxes amene mulibe acid. Mwachitsanzo wopambana, ayendetse. masitolo amagulitsidwa tiwerame rosin kwa kondomu zoimbira. Mwina ntchito soldering. Koma ziwiya zitsulo soldered ntchito rosin-free solder. Kwa kukonza chinkafuna "Rework asidi". Izi kusungunuka acid amathiridwa mu nthaka. Pakompyuta soldering ndi solder momwemonso Sikutheka chifukwa pamapeto pake adzawononga brazing.

Ngati mukufuna kupanga solder mu malo kufikako, m'pofunika kukhala kamwazi madzi. Iwo akhoza kukhala paokha. Rosin wasweka mu ufa, izo anazitsanulira mwa acetone kapena ethyl mowa. A njira analimbikitsa ayenera kuthira rosin kwambiri mpaka pasty misa wandiweyani. Mu malo soldering utomoni madzi kugwiritsidwa ntchito burashi kapena ndodo. Pankhaniyi, pali nuance - kuyang'anira wa matabwa kusindikizidwa dera kasakanizidwe ayenera kukhala madzi. Pakuti mwakhama kufika malo, mukhoza kugwiritsa ntchito solder waya ndi rosin, zomwe zambiri yabwino.

Pamene akugwira fluxes osiyana ayenera kuwaganizira kuti iwo amene wapangidwa acetone, - poizoni kwambiri. Choncho, ntchito ndi iwo kupewa nthunzi inhalation. Kuikira bwino pafupi ndi windo, ngati yotentha, ndiponso m'nyengo yozizira nthawi zambiri ventilate chipinda imene amagwira ntchitoyo. UKAMALIZA onetsetsani kuti kusamba m'manja ndi sopo ndi madzi ofunda.

Kodi solder solder ndi rosin

Mkhalidwe zofunika kwa soldering ukuyenda ndi ukhondo wa pamalo amene ayenera solder. Onetsetsani kuti solder mfundo woyera kuwala ndi. tsatanetsatane ndiye muyenera kuika pa chidutswa cha rosin ndi ofunda. The osungunula rosin solder zidzakhala zofalikira wogawana pa guidewire kapena mfundo mukufuna solder. N'zotheka molondola atembenuza katunduyo, kuthamanga ndi chitsulo soldering kwa solder unaturuka wogawana kudutsa pamwamba.

Ngati ndi kotheka zaludit wochititsa amene soldered kuti bolodi, pambuyo kukolola malo a soldering ndi sandpaper kapena mpeni ndikofunikira kubweretsa chidutswa cha rosin, kenako solder bwino kugawira monga wogawana ngati n'kotheka, kuthera soldering.

Pa khalidwe soldering zimakhudzira ndi mmene chikugwirizana ndi mawaya soldering kapena kulankhula zambiri. Iwo ayenera mwamphamvu mbamuikha pamodzi, ndipo anakonza kubweretsa ochititsa soldering kukhudza izo. Pambuyo solder mkangano adzakhala anafalikira padziko, Gulf ngakhale mipata kakang'ono pakati pa iwo, soldering chitsulo ayenera kuchotsedwa.

mosalekeza soldering nthawi akhale osapitirira masekondi asanu. Patapita nthawi ino, solder solidifies ndi mfundo udzakhazikika angongole. Komabe, kuti si kuwononga soldering, mbali sungakhoze kusunthidwa masekondi 10-15 pambuyo soldering kutsekedwa. Apo ayi, kugwirizana ndi osakhazikika.

Ngati mukuchita ndi transistors, anapeza ayenera kutetezedwa kupewa kutenthedwa. Ndi bwino kuwasunga kapena pliers kapena tweezers, kuchita kutenthaku madyaidya ndikuledzera.

Pamene soldering zigawo zikuluzikulu zamakono Mulimonsemo si koyenera kuti kupotokola malekezero a mbali. Ngati mukufuna solder mbali kapena m'malo akuwauza, m'pofunika ndikuganiza pasadakhale za izo isanafike unsembe. Malekezero a m'madera ambiri zolondola soldering pa mtunda yaing'ono Chrixitu, osati pa malo amodzi.
