Lub ntsej muag tau pom ntau qhov kev thov ntawm cov tub ntxhais kawm thaum lub sijhawm xeem thiab ntsuas. Txawm li cas los xij, nws thiaj li tshwm sim uas nws kim rau yuav lub ntaus ntawv no. Hauv qhov no, koj tuaj yeem sib sau nws tus kheej.
Tsim nyog
- - soldering hlau;
- - daim duab microwell;
- - roj teeb;
- - cov ntsiab lus ntawm Circuit Court.
Cov Lus Qhia
Kauj ruam 1
Yuav txhua qhov tsim nyog rau lub pob ntseg. Lawv tuaj yeem nrhiav tau hauv khw lossis yuav hauv online. Qhov loj tshaj plaws yog kom nco ntsoov tias cov khoom me me ntawm cov khoom siv, nws qhov pom ntau dua nws yuav yog. Koj yuav xav tau transistors sot23 ntawm VS847S, KT3130B9, VS847V hom, capacitors nrog tus nqi nominal ntawm 0.1 μF, nti resistors nrog tus nqi nominal ntawm 10 kOhm, 43 kOhm, 560 kOhm. Lub suab tso tawm yuav yog lub xov tooj hluav taws xob me me, piv txwv, TEM-1956.
Kauj ruam 2
Nrhiav lub micro-earphone Circuit Court hauv Is Taws Nem. Kawm nws kom zoo thiab xyuas yog tias koj muaj cov khoom uas xav tau. Nqa ib pawg thawj coj ntawm qhov yuav tsum loj thiab ham tag nrho cov ntsiab raws li cov kev cai dav dav rau SMD cov ntsiab. Tom qab koj ua tiav soldering, ntxuav lub rooj tsavxwm los ntawm flux thiab kos nrog multimeter uas nws tau ua kom raug thiab tsis muaj luv luv ntawm cov khoom.
Kauj ruam 3
Ua kom tau txais qhov sib tw ntawm cov hlau tsis xeb PEV-2 thiab cua txog 70-100 lem rau ntawm microcircuit. Muag qhov kawg ntawm cov hlau mus rau lub rooj tsavxwm raws li cov lus pom zoo ntawm daim duab thaiv micro-earphone.
Kauj ruam 4
Ua cov fasung uas lub roj teeb yuav raug txhim kho kom ua lub zog ntawm pob ntseg. Nws tuaj yeem tsim los ntawm cov khoom siv hlau tsis nruj. Piv txwv li, noj 5 kopeck npib thiab khoov nws hauv qab kub. Muag lub fasung rau ntawm lub rooj tsavxwm thiab yaug tawm ntawm flux. Txheeb xyuas lub Circuit Court luv nrog multimeter.
Kauj ruam 5
Ntxig lub roj teeb rau hauv fasung. Txheeb xyuas suab. Txhawm rau ua qhov no, kov nrog tweezers lossis lub hau ntswj ntsia hlau rau lub hauv paus ntawm transistors, yog tias koj hnov nws lub suab, nws txhais tau tias kev sib dhos ntawm lub cuab yeej tau ua yog lawm. Tom qab ntawd, sib sau ua ke lub mloog pob ntseg rau hauv rooj plaub los yog qhwv nws nrog kab xev hluav taws xob. Siv cov hlau tuab, ua rau lub pob ntseg, uas tseem qhwv nrog kab xev hluav taws xob lossis lwm yam khoom kom yooj yim siv.
