Taw qhia rau cov yam ntxwv ntawm tus cwj mem zoo li hluav taws xob hlau thiab taw tes hluav taws xob hlau
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 rau 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 tsuas yog soldering ntawm plug-in Cheebtsam. Thaum ua qee qhov kev xav tau yooj yim soldering, koj tuaj yeem siv hluav taws xob tsis zoo.
2. Taw tes soldering hlau
Vuam chaw nres tsheb feem ntau yog qhov ntsuas kub-kho tau, thiab qee qhov tau nruab nrog cov phom cua sov. 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 lub taw tes hluav taws xob soldering hlau, qhov ntsuas kub tuaj yeem hloov kho li ntawm 350 rau cov khoom siv hluav taws xob dav dav. Thaum lub PCBA muaj lub kiv cua-tsim cua sov tsim, qhov kub thiab txias tuaj yeem hloov kho kom tsim nyog kom ntseeg tau tias qhov kub thiab txias tuaj yeem yaj cov tin ntawm PCBA.
Vim tias riam ntug ntawm lub taub hau hlau tuaj yeem ua haujlwm zoo rau cov pins ntawm SOP / TSSOP / LQFP pob, nws yuav yooj yim dua thaum desoldering.
