Yuav ua li cas solder lub SMD teeb hlaws?
Yuav ua li cas solder lub SMD LED chips_Welding txoj kev ntawm SMD LED
Siv cov tweezers txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws nws yuav tsum tau ua tib zoo tuav cov hlau ntawm 1 kawg los yog cov hlua khi, tab sis yuav tsum ceev faj kom tsis txhob quab yuam cov yas ntawm lub teeb lub teeb, los yog nws yuav ua mos thiab nyem thaum cov hlau soldering yog rhuab. Yuav nco ntsoov). Qhov ntsuab kawg yog tus ncej tsis zoo.
2. Muab ib qho me me ntawm cov tin paste rau ntawm cov hlau. Koj tuaj yeem pom daim duab kom paub meej ntxiv. Yog tias koj muaj kev paub ntau ntxiv, koj yuav paub ntau npaum li cas tsim nyog.
3. Cov hlau nplaum sab laug thiab sab tes xis, ua ntej so lub hau ntawm cov hlau soldering kom huv si, thiab tom qab ntawd kov ib feem ntawm cov hlau nrog cov tshuaj txhuam rau hauv cov hlau ntawm cov seem LED, maj mam coj mus rau nws nrog lub soldering hlau. Tsis txhob siv sij hawm ntev heev kom pom tias cov tshuaj txhuam hniav yuav ci iab Hlau zoo nkauj (nco ntsoov tsis txhob muab cov khoom siv hlau, vim tias cov cua sov dissipation zoo dua, qhov vuam kub yuav tsis nce), yog tias nws tsis yog. ua tiav, so nws kom huv si thiab rov qab mus rau kauj ruam 2. (Ntau qhov kev xyaum ntawm no) Tom qab soldering, siv cov tweezers hlau los pab dissipate tshav kub, thiab ceev faj kom hlawv nws.
4. Tom qab soldering raws li qhia saum toj no, so tawm cov tin paste ntau dhau, thiab tig rau sab nraud li 234.
5. Tiav lawm, txuas lub hwj huam mov sim! Nws raug nquahu kom yuav ob peb lub rooj tsav xwm hauv Circuit Court los ua ib qho kev sim ntsuas ntawm koj tus kheej.
Txoj kev soldering ntawm SMD LED teeb hlaws
Ib, manual welding
1. Nws raug pom zoo kom siv reflow soldering nyob rau hauv ib txwm muaj, thiab phau ntawv soldering tsuas yog thaum yuav tsum tau kho.
2. Lub zog siab tshaj plaws ntawm cov hluav taws xob siv hluav taws xob siv rau kev siv phau ntawv soldering yuav tsum tsis pub tshaj 30W, qhov kub thiab txias yuav tsum tau tswj tsis pub dhau 300 ℃, thiab lub sijhawm soldering yuav tsum tsawg dua 3 vib nas this.
3. Tsis txhob kov lub soldering hlau soldering ntsis rau SMD LED teeb hlaws gel kom tsis txhob kub kub puas rau lub teeb LED hlaws.
4. Thaum tus pin yog rhuab mus rau 85 ℃ los yog siab tshaj qhov ntsuas kub no, SMD LED teeb hlaws tsis tuaj yeem nias, txwv tsis pub cov hlau kub yuav raug tshem tawm yooj yim.
2. Reflow soldering
1. Lub ncov kub ntawm reflow soldering: 260 ℃ los yog qis dua tus nqi no (qhov kub ntawm lub teeb hlaws).
2. Lub sij hawm xav tau rau qhov kub siab tshaj 210 ° C: 30 vib nas this los yog tsawg dua.
3. Reflow soldering feem ntau ua ib zaug, thiab tsis pub ntau tshaj ob zaug.
4. Tom qab reflow soldering, LED teeb hlaws yuav tsum tau txias rau hauv chav tsev kub ua ntej lawv tuaj yeem kov lub ntsej muag ntawm LED gel.
