Taw qhia rau cov yam ntxwv ntawm soldering hlau hauv daim ntawv cwj mem thiab hauv daim ntawv taw tes
1. cwj mem-zoo li tus soldering hlau
Hom hluav taws xob soldering hlau feem ntau yog taw qhia, thiab muaj ob hom: kho qhov kub thiab txias tsis hloov.
Nws cov yam ntxwv yog: pheej yig tus nqi, haum rau soldering plug-in Cheebtsam, non-adjustable cwj mem-zoo li tus hluav taws xob soldering hlau, oxidized nrog lub sij hawm ntev kub, thiab lub ntsis ntawm lub ntsis yog tsis tinned.
Rau hom LQFP pob thiab TSSOP pob, cov taw qhia cov hlau yog feem ntau tsis yooj yim rau siv, thiab nws tsis tuaj yeem hloov nrog rab riam-ntug soldering hlau taub, uas muaj kev txwv loj.
Nws yog tsuas yog vuam ntawm plug-in Cheebtsam. Thaum ua qee qhov kev xav tau yooj yim vuam, koj tuaj yeem siv cov khoom siv hluav taws xob tsis zoo.
2. Taw tes soldering hlau
Cov chaw kho mob feem ntau yog qhov ntsuas kub-kho tau, thiab qee qhov muaj cov phom kub. Tus thawj yog taw tes, tab sis vim yog cov qauv kev sib raug zoo, nws tuaj yeem hloov tau nrog rab riam-edged.
Thaum siv cov hlau taw qhia, qhov ntsuas kub tuaj yeem hloov kho li ntawm 350 rau cov khoom siv hluav taws xob dav dav. Thaum muaj cov kiv cua kub tsim ntawm PCBA, qhov kub tuaj yeem nce ntxiv kom tsim nyog los xyuas kom meej tias qhov kub tuaj yeem yaj cov tin ntawm PCBA.
Vim tias riam ntug ntawm lub taub hau hlau tuaj yeem ua tau zoo rau cov pins ntawm SOP / TSSOP / LQFP pob, nws yuav yooj yim dua thaum lub sij hawm desoldering.
Yuav ua li cas xaiv ib tug soldering hlau?
(1) Thaum soldering integrated circuits, transistors thiab cov khoom uas yooj yim rau cua sov, xav txog siv 20W sab hauv cua sov los yog 25W sab nraud cua sov hluav taws xob soldering hlau.
(2) Thaum welding thicker xov hlau los yog coaxial cables, xav txog siv 50W sab hauv cua sov hom los yog ib tug 45-75W sab nraud cua sov hom hluav taws xob soldering hlau.
(3) Thaum soldering cov khoom loj dua, xws li cov hlau chassis grounding pads, yuav tsum siv cov hluav taws xob hluav taws xob siab tshaj 100W.
(4) Cov duab ntawm cov hlau taub hau yuav tsum yoog raws li qhov xav tau ntawm cov khoom siv vuam thiab qhov sib dhos ntom ntom ntawm cov khoom.
Txhawm rau muab nws yooj yim, lub zog thiab hom ntawm cov hlau soldering yuav tsum raug xaiv kom haum raws li cov khoom siv vuam. Yog tias qhov vuam loj dua, lub zog ntawm cov hlau siv yuav tsum siab dua. Yog hais tias lub hwj chim me me, qhov kub ntawm soldering yuav tsawg dhau thiab cov solder yuav yaj maj mam. Lub flux tsis yooj yim rau volatilize, thiab cov pob qij txha ntawm cov pob qij txha tsis du thiab ruaj khov, uas yuav ua rau muaj qhov tsis zoo ntawm qhov zoo thiab lub zog vuam, thiab txawm tias lub vuam tsis tuaj yeem yaj, thiab vuam tsis tuaj yeem nqa tawm. Txawm li cas los xij, lub zog ntawm cov hluav taws xob soldering hlau yuav tsum tsis txhob loj dhau. Yog tias nws loj dhau, cov cua kub ntau dhau yuav raug xa mus rau qhov chaw ua haujlwm yuav tsum tau welded, thiab cov pob qij txha ntawm cov khoom yuav raug overheated, uas yuav ua rau cov khoom puas tsuaj, thiab cov ntawv ci tooj liab ntawm cov ntawv luam tawm Circuit Court yuav poob. thiab lub solder yuav puas. Qhov ntws ntawm qhov chaw vuam yog nrawm heev thiab tsis tuaj yeem tswj tau, thiab lwm yam.
