Cov kev cai ntawm soldering kub thiab vuam lub sij hawm ntawm hluav taws xob soldering hlau
Hais txog cov kev cai ntawm lub vuam kub thiab vuam lub sij hawm ntawm cov hluav taws xob soldering hlau, lub sij hawm vuam ntawm cov hluav taws xob soldering hlau yog 2s / point. Nws yog qhov zoo tshaj kom tsis pub tshaj 3s / point. Lub vuam kub ntawm cov hluav taws xob soldering hlau muaj qhov xav tau qhov kub thiab txias raws li cov khoom sib txawv yuav tsum tau welded. Sib txawv, muaj cov kev cai ntawm qhov kub thiab txias thiab lub sij hawm ntawm cov hluav taws xob soldering hlau.
Cov kev cai ntawm soldering kub thiab vuam lub sij hawm ntawm hluav taws xob soldering hlau
Soldering lub sij hawm ntawm hluav taws xob soldering hlau:
2s / taw tes yog qhov zoo tshaj plaws, nws yog qhov zoo tshaj kom tsis pub tshaj 3s / taw tes
soldering hlau soldering kub
1. Qhov kub ntawm cov hlau soldering rau thaj ua rau thaj, coding keyboards thiab lwm yam khoom yog 343 ± 10 degree;
2. Cov kub kub rau vuam xim nplhaib resistors, ceramic capacitors, tantalum capacitors, luv Circuit Court blocks thiab lwm yam khoom yog 371 ± 10 degree;
3. Thaum kho cov khoom siv dav dav (xws li IC), qhov kub ntawm cov hlau yuav tsum nyob rau hauv 350 ± 20 degree;
4. Thaum kho lub hwj chim modules nrog tuab pins, transformers (los yog inductors), loj electrolytic capacitors thiab loj-qhov chaw tooj liab ntawv ci pads, lub soldering hlau kub yuav tsum yog 400 ± 20 degree.
5. Qhov ntsuas kub ntawm cov hlau soldering hauv SMT, kev sib dhos thiab kev tshuaj ntsuam xyuas, thiab cov xov tooj ntawm tes yog nruj me ntsis raws li qhov ntsuas kub hauv qhov chaw tsim khoom tshuaj xyuas thiab vuam cov lus qhia;
6. Lead-free tshwj xeeb soldering hlau, kub yog 360 ± 20 degree.
Thaum vuam thiab disassembling thaj thaj tsam, koj yuav tsum hnav lub nplhaib electrostatic. Lub nplhaib electrostatic tseem hu ua electrostatic wristband. Nws yog feem ntau yog ib tug dav thiab nruj band ua los ntawm conductive fiber.
Lub luag haujlwm tseem ceeb: Tiv thaiv cov khoom siv hluav taws xob los ntawm kev tawg los ntawm hluav taws xob zoo li qub. Thaum siv nws, nco ntsoov txuas hauv av xaim, txwv tsis pub nws yuav yog "hauv lub npe nkaus xwb" thiab yuav tsis ua haujlwm.
