Yam dab tsi ntawm lub taub hau hlau yog qhov zoo rau cov khoom siv thaj
Raws li cov duab, lub taub hau hlau tuaj yeem muab faib ua cov lus taw qhia, lub ntsej muag zoo li lub taub hau, lub taub hau lub taub hau, lub taub hau riam, thiab lwm yam, thiab tuaj yeem muab faib ua ntau yam raws li qhov loj me. Feem ntau, cov duab siv ntau dua yog taw qhia cov lus qhia hlau thiab cov lus qhia riam-ntug soldering hlau.
Thaum soldering li nrog ib tug me me pins, xws li nti resistors, nti capacitors, nti inductors thiab lwm yam ob-terminal Cheebtsam, raws li zoo raws li SOT-23 pob khoom, siv ib tug taw tes soldering hlau taub, thaum vuam ntau pins. Chips, xws li LQFP pob, TSSOP tej pob khoom, SOP tej pob khoom, thiab lwm yam., siv riam-ntug soldering hlau tswv yim, vim hais tias riam-ntug soldering hlau tswv yim yuav dragged thiab soldered, thiab vuam efficiency yog kuj siab.
Txawm li cas los xij, qhov twg soldering hlau taub siv yog nyob ntawm tus neeg siv tus kheej tus cwj pwm, thiab nws yog qhov zoo tshaj plaws los siv rau nws.
Cov ntsiab lus yuav tsum nco ntsoov thaum soldering nrog hluav taws xob soldering hlau:
1. Ua ntej siv cov hlau soldering, xyuas seb cov hlau nplaum puas yog av zoo.
2. Ua ntej welding, ua tib zoo saib seb lub zog ntawm cov hlau soldering puas haum rau qhov taw tes.
3. Ntxuav lub hau ntawm cov hluav taws xob soldering hlau nrog ib daim txhuam cev thiab tom qab ntawd tin-phaj nws.
4. Ntxuav thiab tin-phaj cov khoom siv soldered, thiab ces solder lawv. Qhov kub thiab txias yuav tsum tsis txhob siab dhau thiab lub sij hawm yuav tsum tsis txhob ntev heev thaum soldering.
5. Ua tib zoo saib xyuas cov permeability ntawm cov pob qij txha, qhov kev ncua deb ntawm cov ntsiab lus, thiab kev sib koom ua ke ntawm rosin thiab solder paste.
6. Tom qab welding, nco ntsoov xyuas seb puas muaj cov welds cuav, tsis muaj welds, welds tsis raug, luv Circuit Court, thiab lwm yam.
vuam taw qhia
1. Yuav ua li cas tuav cov hlau soldering
(1) Yuav tuav tus cwj mem li cas. Haum rau lub teeb yuag hlau, xws li 30W sab hauv cov cua sov soldering hlau. Nws lub taub hau ntawm lub taub hau yog ncaj, thiab lub taub hau kawg yuav raug xa mus rau hauv ib qho bevel lossis conical zoo, uas yog tsim rau cov ntaub qhwv ntsej muag nrog thaj tsam me me.
(2), kev siv lub nrig. Haum rau siab zog soldering hlau.
2. Muaj ntau txoj hauv kev ntawm soldering ua rau ntawm cov ntawv luam tawm hauv Circuit Court.
(1) Ncaj nraim ntawm lub taub hau txiav. Cov hlau lead mus ncaj qha mus rau hauv lub qhov. Thaum soldering, ua kom tus nqi tsim nyog ntawm molten solder tusyees nyob ib puag ncig cov tinned leads saum lub ncoo, thiab txiav tawm cov hlau lead ntau dhau.
(2), faus ncaj qha. Cov hlau lead los ntawm lub qhov tsuas yog raug rau qhov ntev uas tsim nyog, thiab cov molten solder faus cov hlau lead hauv qhov sib koom ua ke.
3. Tiv thaiv kev vuam tsis zoo
1. Xaiv cov solder haum, tsis tshua muaj melting point solder hlau rau vuam cov khoom siv hluav taws xob yuav tsum tau xaiv.
2. Flux, siv 25 feem pua rosin yaj hauv 75 feem pua ntawm cawv (los ntawm qhov hnyav) raws li flux.
3. Txoj kev soldering, polish lub ncoo thiab tivthaiv pins nrog zoo xuab zeb, thiab siv flux.
4. Lub sijhawm vuam yuav tsum tsis txhob ntev dhau, txwv tsis pub nws yuav yooj yim rau hlawv cov khoom.
5. Cov kev sib xyaw ua ke yuav tsum tau soldered kawg, thiab cov hluav taws xob soldering hlau yuav tsum muaj kev ntseeg siab hauv av, los yog siv cov hluav taws kub uas seem rau soldering tom qab fais fab tuag.
