Tsim nyog qhov chaw ntawm soldering hlau kub:
a): Kho cov khoom tsis muaj hlau lead SMD
1) Kho cov khoom zoo tib yam xws li 0603, 0805, 3216 Cheebtsam, qhov kub ntawm cov hlau: 350 degree ± 50 degree.
2) Kho IC, qhov kub ntawm cov hlau soldering yog 350 degree ± 50 degree:
3) Rau kev kho cov khoom siv hlau lossis cov khoom siv nrog thaj tsam loj thiab cov cua sov sai sai, qhov kub ntawm hluav taws xob soldering hlau: 380 degree ± 50 degree.
b): Kev saib xyuas cov khoom tsis muaj hmoov txhuas THD
1) Kho cov khoom siv zoo tib yam xws li 1/4W.1/2W resistors, me me triodes, capacitors nrog qis voltage hauv me me, ICs, diodes thiab lwm yam me me. Qhov ntau ntawm cov hlau kub: 340 degree ± 50 degree.
2) Kho cov khoom siv hlau uas muaj cov khoom siv hluav taws xob xws li radiators, electrolytic capacitors nrog lub siab sab hauv thiab muaj peev xwm loj, lub zog hluav taws xob diodes, hluav taws kub nyuj thiab lwm yam khoom loj. Qhov kub ntawm cov hlau soldering: 380 degree ± 50 degree.
3) Kho cov hlau txuas nrog cov tawv nqaij, qhov kub ntawm cov hlau soldering: 350 ± 50 degree
Lub zog ntawm cov hlau soldering muaj ntau yam ua rau qhov kub thiab txias ntawm cov hlau soldering, tab sis lub zog siab tsis tas txhais tau tias kub siab. Lub tshuab hluav taws xob tsis tshua muaj hluav taws xob tsis tas yuav tsum muaj qhov ntsuas kub tsawg, tab sis lub zog hluav taws xob muaj zog yuav tsum muaj cua sov ntau, thiab qhov ceev ntawm rov qab mus rau qhov kub kuj tseem ceev heev, yog li kev xaiv kub ntawm cov hlau soldering yuav tsum yog. ua raws li cov khoom siv soldering.
