Ndimakonda kupanga zinthu zaulere zodzaza ndi malingaliro kwa owerenga anga, inunso. Sindimavomereza ndalama zolipiridwa, malingaliro anga ndi anga, koma mukawona malingaliro anga akuthandizani ndipo mumatha kugula china chake chomwe mumakonda kudzera paulalo mwanga, nditha kupeza ntchito popanda mtengo wowonjezera kwa inu. Dziwani zambiri
Soldering ndiyabwino kwambiri kosatha. Komabe, mutha kuwonongekeratu ngati kuchotsa solder pogwiritsa ntchito pampu yosungunulira ndi chitsulo chosungunulira. Koma zimakhala zovutirapo mukakhala kuti mulibe zonsezi ndipo mukusowa kolowera mwachangu.
Mu positi iyi tikambirana:
Kugwiritsa Ntchito Flat Head Screwdriver
Screwdriver ndi chida chofala kwambiri chomwe chingapezeke pafupifupi pazida zilizonse. Ngakhale adapangidwa kuti ajowine, titha kuwagwiritsiranso ntchito mosiyana. Momwemo, chopukutira mutu chopanda pake ndichosankha pamutu pake wokulirapo. Komabe, masitepe ochepawa atha kutsogolera njira ina yabwino.Gawo 1: Pukutani Tip
Tengani chowongolera pamutu ndikuthira mutu wake ndi nsalu yoyera komanso youma. Izi zitsimikizira kuti palibe okusayidi kapena dzimbiri zotsalira pamutu pamutu. Nayi nsonga! Sankhani chowombera chakale kwambiri m'sukulu yanu. Pomwe chowotcheracho chimakhala chotenthedwa kwambiri ndipo pambuyo pake chimakhazikika, chimakhala chotsuka.
Gawo 2: Kutenthe
Pakutentha kwa screwdriver, tochi ya propane ndiye njira yabwino kwambiri. Itha kupanga lawi mpaka 2000 mpaka 2250 madigiri Fahrenheit. Mosiyana tochi ya butane yomwe imagwiritsidwa ntchito kusungunula mapaipi amkuwa, tochi ya propane imatulutsa lawi lowala kwambiri. Gwiritsani screwdriver pamoto wa tochi ya soldering ndipo dikirani mpaka chitsulo chisanduke chofiira. Chitani izi moyandikira kwakanthawi momwe mungathere.
Gawo 3: Sungunulani Solder Down
Tsopano yakwana nthawi yoti mukhudze solder ndi nsonga ya screwdriver yotentha. Koma muyenera kukhala osamala kwambiri kuti mugwiritse ntchito kutentha kokha pamagulu omwe mukufuna, osati mbali zina za dera. Malo athyathyathya ndi mnzake woyenera pantchitoyi. Onetsetsani kuti PCB yakhazikika mofanana pamtunda. Ndiye yesani kupeza pachimake pa solder kapena kuwira. Kukhudza pang'ono ndikokwanira kuti pakhale kulumikizana kofunikira pakati pa nsonga ya screwdriver ndi kuwira. Pambuyo pake pewani pansi ndipo chosungunuka chimayamba kusungunuka.
Gawo 4: Chotsani Solder
Mukasungunuka bwino, muyenera kuwachotsa pa PCB. Apanso, zowombazo zayamba kupulumutsa! Tengani chowombera chomwe nthawi zambiri chimayenera kukhala chitakhazikika tsopano ndikuchigwira ndi solder. Posakhalitsa solder adzatsatira screwdriver. Mutha kugwiritsa ntchito chowombera china ngati choyambacho sichingakhale chokwanira.
Gawo 5: Pukutani Tip
Apanso tenga nyali ya propane ndikuyiyatsa moto. Gwirani chowombera pamoto. Kenako pukutani pamwamba ndi nsalu. Chifukwa chake zotsalira zotsalira zomwe zili pamtunda zimatha kutsukidwa chimodzimodzi momwe mumatsukitsira chitsulo.
Kwa Kupulumutsa Zigawo Zosakhwima Kuchokera ku Circuitry Yamagetsi
Inu mukhoza ndithudi chotsani solder kuchokera ku PCB iliyonse ndi njira yomwe yatchulidwayo. Koma pali zolakwika zina. Kutentha komwe mukugwiritsa ntchito pa bolodi kumatha kuwononga zinthu zina zovuta pa bolodi. Ndicho chifukwa chake pakufunika china chomwe chingachotse mosamala zigawozo. Ngakhale munjira izi, kutentha ndikofunikira. Koma pali njira zina zomwe zimagwiritsidwa ntchito kuteteza kutentha ndikuwononga malo ozungulira.
1. Mwa Kutentha Pokwerera Mmodzi
Osati kwenikweni kuti muzitha kutentha malo onse ophatikizira panthawi. Mutha kuyika kutentha mmodzimmodzi. Njira imeneyi imakhala yothandiza kwambiri mukakumana ndi zovuta kuzimitsa. Chitsulo chotsitsa chotsika chitha kugwiritsidwa ntchito kupatsa kutentha. Kuphatikiza apo, kukhazikitsa koziziritsira pafupi ndi chinthuchi kumatha kukhala kotheka kwambiri kuchotsa kutentha kosafunikira.
2. Pogwiritsa Ntchito Hot Air Gun ndi Suction Pump
Mfuti zotentha zitha kuwotcha mpweya ku PCB ndipo pamapeto pake zimatha kupanga solder kutentha kokwanira. Kugwiritsa ntchito mfuti yotentha ndi njira yodziwikiratu yomalizira ntchito. Koma anyamatawa amakonda kusakaniza zida zina zachitsulo kuzungulira. Ndicho chifukwa chake kugwiritsa ntchito mpweya wa nayitrogeni ndi kotetezeka. Ngakhale zida izi zimatha kuwomba mpweya wotentha kumalumikizidwe koma solder yomwe imatulutsira ku PCB imayenera kuchotsedwa. Pampu yokoka yopangidwa mwapadera kapena solder sucker imafunika kuti muchotse solder. Kugwiritsa ntchito zida izi kumatsimikizira kuti palibe chinthu china chomwe chimakhudzidwa kapena kusatsekeka kosafunikira kwa solder kumachitika.
3. Kugwiritsa Ntchito Maphukusi a Quad Flat Kuti Muchotse Magawo Osiyanasiyana
Ngati mukufuna kupulumutsa IC kuchokera ku PCB, palibe chifukwa chogwiritsa ntchito chitsulo chosungunula mwachindunji. Zachidziwikire, simungathe kuwotcha malo onse a IC nthawi yomweyo ndi chitsulo chosungunula. Ngakhale kugwiritsa ntchito mfuti yotentha mopanda malire sikungabweretse zotsatira zomwe mukufuna. Pankhaniyi, muyenera kugwiritsa ntchito phukusi la quad lathyathyathya. Kapangidwe koyambirira ka QFP ndikosavuta. Ili ndi zitsogozo zopyapyala zomwe zimadzaza pamodzi komanso makoma anayi owonda omwe amateteza kutentha. Ili ndi kasupe yemwe amasungira IC kumtunda pomwe solder ikafika pamadzi. Pambuyo pokonza bwino QFP, muyenera kuwomba mpweya wotentha kuchokera mfuti yotentha. Kutentha kutagwera pamalo omwe amafunikira makoma ochepawo, solder m'deralo amalandila kutentha. Posakhalitsa muli ndi ufulu wokweza IC pogwiritsa ntchito makina opanga. QFC ina imakhala ndi zikwangwani zowonjezera zomwe zimateteza zigawo zina zadongosolo kuti zisadzipatule.
Njira Yopanda Nzeru
Ngati mukuganiza kuti PCB yakula mokwanira ndipo singagwiritsenso ntchito, mutha kugwiritsa ntchito njira zina zopanda nzeru zomwe zingakuthandizeni kupulumutsa zigawozo. Onani!1. Dulani Malo
Mutha kudula malo azipangizo zosafunikira ndikuwatulutsa. Gwiritsani ntchito lezala pantchitoyi. Kuphatikiza apo, wothandizira angathandize kwambiri kuti athetse mgwirizano wa solder ndi kutulutsa chigawocho. Koma samalani ndi dzanja lanu mukamagwiritsa ntchito mphamvu. Ndi bwino kuvala magolovesi.
2. Dinani Mwakhama Pamwamba Panyumba Iliyonse
Izi zitha kuwoneka zoseketsa koma kugwedeza bolodi pamalo olimba ndiye njira yomaliza yoswa cholumikizira. Ngati simukusowa bolodi koma zigawo zake zokha, mutha kugwiritsa ntchito njirayi. Kuwonjezeka kwamphamvu kwakusokonekera kumatha kuswa solder ndikupangitsa kuti chigawo chake chikhale chaulere.
pansi Line
Pakadali pano mukudziwa momwe mungachotsere solder popanda chitsulo. Si mtedza wolimba kuswa. Ngakhale nthawi zina kugwiritsa ntchito chitsulo cha soldering sikutetezeka. Koma kumbukirani njira iliyonse yomwe mungatenge, onetsetsani kuti mukugwira ntchito pamalo athyathyathya ndipo musakhudze chosungunuka ndi dzanja.
