Zigawo za chip ndi zazing'ono komanso zazing'ono zopanda ma lead kapena njira zazifupi, zomwe zimayikidwa mwachindunji pa PCB ndipo ndi zida zapaderapamwamba msonkhano luso.Zigawo za chip zili ndi ubwino wa kukula kwazing'ono, kulemera kwake, kusasunthika kwakukulu, kudalirika kwakukulu, kukana kwamphamvu kwa zivomezi, makhalidwe abwino afupipafupi, mphamvu zotsutsana ndi kusokoneza, komanso chifukwa cha kuchuluka kwake kochepa, kuopa kutentha, kuopa kukhudza. , zikhomo zina zotsogola zimakhala zambiri, zimakhala zovuta kuzigawa, zomwe zimabweretsa zovuta kwambiri pakukonza.
Njira zodziwika bwino za disassembly ndi izi.Ndikofunika kuzindikira kuti: pakuwotcha kwapafupi, tiyenera kupewa magetsi osasunthika, ndipo mphamvu yachitsulo yamagetsi ndi kukula kwa mutu wachitsulo ziyenera kukhala zoyenera.
I. Njira yotengera machimo amkuwa
Suction mkuwa ukonde amapangidwa ndi waya wabwino mkuwa wolukidwa mu lamba reticulated, akhoza m'malo ndi chitsulo chitetezero mzere chingwe kapena zingwe zambiri za waya wofewa.Mukagwiritsidwa ntchito, phimbani chingwe pa pini yambiri ndikuyika rosin mowa flux.Kutentha ndi chitsulo soldering, ndi kukoka waya, solder pa mapazi ndi adsorbed ndi waya.Dulani waya ndi solder ndikubwereza kangapo kuti mutenge solder.Solder pa pini pang'onopang'ono amachepetsa mpaka pini ya chigawocho imasiyanitsidwa ndi bolodi losindikizidwa.
II.Njira yapadera yothetsera mutu wachitsulo kusankha ndi kugula mutu wapadera wachitsulo "N" wooneka ngati chitsulo, mapeto a notch m'lifupi (W) ndi kutalika (L) akhoza kutsimikiziridwa molingana ndi kukula kwa zigawo zomwe zasokonekera.Special chitsulo mutu akhoza solder wa zikhomo kutsogolera mbali zonse za dismantled mbali kusungunuka pa nthawi yomweyo, kuti atsogolere kuchotsedwa kwa dismantled zigawo zikuluzikulu.Njira yodzipangira yokha ya mutu wachitsulo ndikusankha chubu chofiira chamkuwa chokhala ndi m'mimba mwake chofanana ndi kunja kwa mutu wachitsulo, kumangirira mbali imodzi ndi vice (kapena nyundo) ndikubowola dzenje laling'ono, monga momwe tawonetsera pa Chithunzi 1 ( a).Kenako mbale ziwiri zamkuwa (kapena machubu amkuwa amadulidwa motalika ndi kuphwanyidwa) amagwiritsidwa ntchito kuti azitha kukula mofanana ndi magawo ophwanyidwa, ndipo mabowo amabowoledwa, monga momwe tawonetsera pa Chithunzi 1 (b).Nkhope yomalizira ya mbale yamkuwa inali yophwanyidwa, yopukutidwa bwino, ndipo potsirizira pake inasonkhanitsidwa mu mawonekedwe monga momwe tawonetsera pa Chithunzi 1 (c) ndi mabawuti, omwe amaikidwa pamutu wa soldering.Mutu wa soldering ukhoza kugwiritsidwa ntchito potenthetsa ndi kuviika malata.Pakuti amakona anayi flake zigawo zikuluzikulu ndi mawanga awiri solder, bola ngati soldering chitsulo mutu wagogoda mu mawonekedwe lathyathyathya, kotero kuti m'lifupi mwake mapeto nkhope ndi wofanana ndi kutalika kwa chigawo, mawanga awiri solder akhoza kutenthedwa ndi kusungunuka nthawi imodzi. , ndipo zigawo za flake zimatha kuchotsedwa.
III.Njira yoyeretsera solder
Pamene solder imatenthedwa ndi chitsulo chosungunula antistatic, solder imatsukidwa ndi mtsuko wa mano (kapena burashi ya mafuta, burashi ya penti, etc.), ndipo zigawozo zingathenso kuchotsedwa mwamsanga.Zigawozi zikachotsedwa, bolodi losindikizidwa liyenera kutsukidwa nthawi yake kuti lisawonongeke mbali zina zomwe zimayambitsidwa ndi zotsalira za malata.
