Soldering hlau-forming, inserting thiab soldering ntawm cov khoom
1. Cov khoom siv tus pin sib sau: Ua cov khoom raws li qhov yuav tsum tau ua thiab tin lawv.
(1) Cov pins tivthaiv yuav tsum tsis txhob khoov los ntawm cov hauv paus hniav, thiab feem ntau yuav tsum khaws cia ntau tshaj 1.5 hli.
(2) Cov txhuas feem ntau yuav tsum tsis txhob khoov rau hauv lub kaum sab xis tuag, thiab lub vojvoog arc yuav tsum siab dua 1 txog 2 npaug ntawm txoj kab uas hla.
(3) Sim muab qhov chaw ntawm qhov sib xyaw nrog cov cim uas nws yooj yim rau kev soj ntsuam.
(4) Rau kev teeb tsa kab rov tav, sab laug thiab txoj cai khoov ntawm ob tus pins yuav tsum sib luag, cov hlau lead yuav tsum yog sib npaug, thiab qhov kev ncua deb ntawm lawv yuav tsum sib npaug rau qhov kev ncua deb ntawm ob lub ncoo qhov ntawm lub rooj tsav xwm luam tawm los pab txhawb. kev teeb tsa.
2. Cheebtsam layout thiab installation
(1) Ua kom zoo nteg tawm cov khoom raws li qhov loj ntawm universal board thiab tus naj npawb ntawm cov khoom siv hluav taws xob, thiab yuav tsum muaj qhov sib txawv ntawm cov khoom sib txawv.
(2) Sim ua kom ntseeg tau tias cov khoom siv pins tsis hla.
(3) Thaum txhim kho cov khoom, lub polarity ntawm diodes, transistors, thiab electrolytic capacitors tsis tuaj yeem thim rov qab lossis tsis raug txuas.
(4) Kev ntxig cov khoom yuav tsum ua raws li cov hauv paus ntsiab lus ntawm me me ua ntej loj, lub teeb ua ntej tom qab hnyav, qis dua ua ntej siab, sab hauv ua ntej ces sab nraud.
(5) Daim ntawv teeb tsa: Cov resistors thiab diodes feem ntau ntsia kab rov tav, uas yog, cov khoom raug muab tso rau kab rov tav ze rau lub rooj tsav xwm luam tawm. Rau cov khoom siv hluav taws xob siab thiab lwm yam khoom, lawv yuav tsum nyob deb 2 ~ 3 hli ntawm lub rooj tsavxwm. Cheebtsam xws li transistors thiab capacitors yog ntsia vertically, uas yog, lub Cheebtsam yog muab tso rau vertically rau hauv lub Circuit Court board, feem ntau yuav tsum tau ib tug deb ntawm 2 ~ 3 hli los ntawm lub board nto.
Ntau qhov teeb meem koj yuav tsum tau them sai sai rau thaum siv cov hlau soldering
(1) Ua ntej siv lub tshuab hluav taws xob tshiab, koj yuav tsum xub xa cov hlau nplaum rau hauv ib qho duab raws li qhov xav tau, thiab tom qab ntawd tig lub zog. Thaum qhov kub ntawm cov hlau taub hau nce mus rau qhov kub uas tuaj yeem yaj lub vuam, siv cov rosin rau ntawm lub taub hau ntawm cov hlau, thiab lwm yam. Tom qab cov rosin haus luam yeeb, thov ib txheej ntawm solder, thiab rov ua cov txheej txheem no kom txog thaum cov hniav npog tag. nrog solder.
(2) Yuav ua li cas los daws qhov teeb meem uas lub taub hau hlau tsis "noj tin": Siv cov ntawv xuab zeb zoo los yog cov ntaub ntawv rov ua dua cov hlau taub hau los yog cov ntaub ntawv tawm tshiab, thiab rov tinning.
(3) Yog hais tias muaj ntau dhau ntawm cov hlau soldering thaum lub sij hawm vuam: so nws nrog ib daim ntaub ntub dej thiab tsis txhob viav vias hlau.
