Kev kho kom zoo reflow tuaj yeem txuas ntxiv nws lub neej voj voog, ua kom lub tshuab zoo, thiab txhim kho kev tsim khoom thiab cov khoom zoo.Ib qho ntawm cov haujlwm tseem ceeb tshaj plaws rau kev tswj xyuas qhov cub reflow kom zoo yog tshem tawm cov khoom seem hauv lub qhov cub chamber.Txawm hais tias muaj cov flux sau system nyob rau hauv cov tshuab reflow niaj hnub, tseem muaj qhov tshwm sim loj heev uas cov flux yuav ua raws li cov kav dej inert cua thiab thermal regulator vaj huam sib luag.Qhov no yuav ua rau cov ntaub ntawv thermal nyeem tsis raug thiab tus tswj thermal yuav ua rau cov lus qhia hloov tsis raug.
Cov hauv qab no yog cov npe ntawm txhua hnub, kev ua haujlwm hauv tsev yuav tsum ua kom tiav rau kev tuav lub qhov cub reflow:
- Ntxuav thiab so lub tshuab txhua hnub.Ua qhov chaw ua haujlwm zoo.
- Tshawb xyuas cov saw conveyor, sprockets, mesh thiab tsis siv neeg lubrication system.Ntxiv lubricate roj raws sijhawm.
- Ntxuav cov hluav taws xob hloov hluav taws xob uas kuaj xyuas seb lub rooj tsavxwm nyob hauv lossis sab nraud ntawm qhov cub reflow.
Cov hauj lwm tu vaj tse ntxiv muaj xws li:
- Thaum lub chamber kub txo mus rau hauv chav tsev kub, qhib lub hood thiab ntxuav lub sab hauv chamber nrog ib tug zoo tu tus neeg sawv cev.
- Ntxuav cov yeeb nkab cua nrog ib tus neeg ua haujlwm tu.
- Nqus chamber thiab tshem tawm cov flux residue thiab soldering npas
- Xyuas thiab ntxuav lub tshuab cua tshuab
- Xyuas thiab hloov lub lim cua
Cov lus hauv qab no yog ib qho piv txwv ntawm lub sijhawm lubrication:
