Kev sib txuas lus ntawm wattage thiab kub ntawm hluav taws xob soldering hlau
Dab tsi yog qhov kub thiab txias rau cov hlau soldering?
Qhov no yog txiav txim los ntawm qhov kev thov tiag tiag ntawm cov hlau soldering. Feem ntau hais lus, qhov kub thiab txias thaum cov hlau soldering tuaj yeem ua lub tin taw tes hauv 4 vib nas this yog qhov ntsuas kub zoo dua. Yog hais tias cov hlau soldering hloov ntshav, nws txhais tau hais tias qhov kub thiab txias siab dhau lawm.
Tshwj xeeb tshaj yog, thaum nws yog ib qho tsim nyog los ntxig cov khoom siv hluav taws xob ncaj qha, qhov kub ntawm cov hlau taub hau yuav tsum tau teem rau ntawm 330-370 degrees. Yog tias nws yog cov khoom siv saum npoo av, qhov kub yuav tsum nyob nruab nrab ntawm 300-320 degrees. Nyob rau ntawm qhov kub ntawm 290 degrees, qhov kub ntawm cov khoom loj ntawm ko taw tsis tuaj yeem tshaj 380 degrees. Tsis tas li ntawd, rau cov ntaub ntawv tshwj xeeb, tshwj xeeb qhov kub thiab txias yuav tsum tau.
Qhov sib thooj kub ntawm cov hluav taws xob soldering hlau fais fab cim
1. Kos 20-25W, thiab qhov sib txuas vuam kub yog 200-250 degrees;
2. Kos 30-35W, thiab qhov sib txuas vuam kub yog 250-300 degrees;
3. Kos 40-45W, thiab qhov sib txuas vuam kub yog 280-350 degrees;
4. Mark 50W, qhov sib txuas vuam kub yog 320-380 degrees;
5. Mark 60W, qhov sib txuas vuam kub yog 320-400 degrees;
6. Kos 75-80W, thiab qhov sib txuas vuam kub yog 350-400 degrees;
7. cim 100W, qhov sib txuas vuam kub yog 380-450 degrees;
Cov wattages sib txawv muaj cov cua kub sib txawv.
Kev tswj kub ntawm hluav taws xob soldering hlau
Rau cov pob qij txha ntawm SMD Cheebtsam thiab nyias-ko taw Cheebtsam (xws li cov xov hlau, LEDs, thiab lwm yam), qhov kub ntawm cov hlau soldering feem ntau yog siv raws li cov qauv hauv qab no:
Lead soldering: qhov kub thiab txias yog tswj ntawm 250-350 degrees;
Cov hlau lead-dawb soldering: qhov kub yog tswj ntawm 320-400 degrees;
Rau cov pob qij txha uas muaj cua sov sai dua thiab ntau dua tin ntxiv (xws li roj teeb zoo thiab tsis zoo polarity, thiab lwm yam), qhov kub ntawm cov hlau soldering feem ntau yog siv raws li cov qauv hauv qab no:
Lead soldering: qhov kub thiab txias yog tswj ntawm 280-380 degrees;
Cov hlau lead-dawb soldering: qhov kub thiab txias yog tswj ntawm 350-420 degrees.
