Kev taw qhia thiab kev faib cov lus piav qhia ntawm hluav taws xob soldering hlau
1. Sab nraud cua sov soldering hlau
Nws feem ntau yog tsim los ntawm lub taub hau hlau, lub taub hau hlau, lub plhaub, lub kov, lub ntsaws thiab lwm yam. Lub ntsiab lus ntawm cov hlau soldering yog ntsia rau hauv cov tub ntxhais hlau soldering thiab yog ua los ntawm cov khoom siv tooj liab alloy nrog tooj liab ua lub hauv paus nrog cov thermal conductivity zoo. Qhov ntev ntawm lub taub hau hlau tuaj yeem hloov kho (qhov luv luv ntawm lub taub hau taub hau, qhov siab dua qhov kub ntawm lub taub hau taub hau), thiab muaj cov duab sib txawv xws li chisel, taw qhia lub khob hliav qab, puag ncig, lub voj voog, taw qhia lub khob hliav qab thiab ib nrab. -circular groove zoo kom hloov mus rau Cov kev xav tau ntawm cov vuam sib txawv.
2. Internal cua sov soldering hlau
Nws muaj tsib ntu: txuas pas nrig, kov, lub caij nplooj ntoos hlav clip, soldering hlau core, thiab soldering hlau taub (tseem hu ua tooj liab tip). Cov tub ntxhais hlau soldering tau muab tso rau hauv lub taub hau ntawm lub taub hau (nws ua kom sov sai, thiab cov thermal efficiency siab li 85% mus rau ntau tshaj %%). Cov tub ntxhais hlau soldering yog ua los ntawm npib tsib xee-chromium tsis kam hlau qhov txhab ncig lub raj plooj (porcelain tube). Feem ntau, qhov tsis kam ntawm 20W soldering hlau yog li 2.4kΩ, thiab ntawm 35W soldering hlau yog li 1.6kΩ.
Feem ntau hais lus, qhov ntau dua lub zog ntawm cov hlau soldering, qhov kub thiab txias ntau dua, thiab qhov kub ntawm cov hlau soldering ntau dua. Ib qho 20W sab hauv cua sov soldering hlau feem ntau yog siv los ua cov khoom sib xyaw ua ke, cov ntawv luam tawm, thiab CMOS circuits. Yog hais tias lub zog ntawm cov hlau soldering siab dhau lawm, nws yog ib qho yooj yim rau hlawv cov khoom (feem ntau, qhov kub thiab txias ntawm lub diode thiab triode yuav kub hnyiab tau thaum qhov kub ntawm qhov kub siab tshaj 200 degree) thiab ua rau cov ntawv luam tawm los ntawm lub substrate. ; Yog hais tias lub zog ntawm cov hlau soldering tsawg dhau, lub solder tsis tuaj yeem yaj tag nrho. , cov flux tsis tuaj yeem evaporate, cov pob qij txha tsis zoo thiab ruaj khov, thiab nws yooj yim los tsim cov khoom cuav. Yog tias lub sijhawm vuam ntev dhau lawm, lub cuab yeej yuav raug hlawv. Feem ntau, txhua qhov taw tes soldering tiav hauv 1.5 txog 4S.
3. Lwm yam soldering hlau
1) Qhov kub thiab txias tsis tu ncua
Lub taub hau ntawm lub taub hau ntawm qhov kub thiab txias tsis tu ncua hluav taws xob soldering hlau yog nruab nrog cov hlau nplaum-hom kub tswj los tswj lub zog ntawm lub sijhawm thiab ua tiav qhov kub thiab txias. Thaum vuam cov khoom uas nws qhov kub thiab txias yuav tsum tsis txhob siab dhau thiab nws lub sij hawm vuam yuav tsum tsis txhob ntev dhau, yuav tsum tau siv qhov kub thiab txias, tab sis nws kim heev.
2) Soldering hlau
Lub desoldering hlau yog ib qho cuab yeej desoldering uas ua ke nrog piston hom desoldering ntaus ntawv thiab ib qho hluav taws xob soldering hlau. Nws yog ib qho yooj yim mus use, hloov tau, thiab muaj ntau yam kev siv. Qhov tsis zoo yog tias koj tuaj yeem tsuas desolder ib qho sib koom ua ke ntawm ib lub sijhawm.
3) Steam soldering hlau
Cov hlau nplaum uas siv cov roj liquefied, methane thiab lwm cov roj hluav taws kub hnyiab los hlawv thiab ua kom sov lub taub hau ntawm cov hlau. Nws yog qhov tsim nyog rau cov xwm txheej uas cov khoom siv hluav taws xob tsis yooj yim lossis AC fais fab tsis tuaj yeem muab tau.
