Cov xwm txheej rau PCB Circuit Board welding

1. Lub vuam muaj qhov zoo weldability
Lub npe hu ua solderability yog hais txog kev ua tau zoo ntawm cov hlau uas tuaj yeem tsim kev sib xyaw ua ke zoo ntawm cov khoom siv hlau yuav tsum tau welded thiab solder ntawm qhov tsim nyog kub. Tsis yog tag nrho cov hlau muaj zoo weldability. Txhawm rau txhim kho kev ua kom zoo dua qub, kev ntsuas xws li nto tin plating thiab nyiaj plating tuaj yeem siv los tiv thaiv cov khoom nto oxidation.

2. Khaws qhov chaw ntawm qhov vuam kom huv
Txhawm rau kom ua tiav kev sib xyaw ua ke zoo ntawm cov khoom siv thiab vuam, qhov vuam nto yuav tsum tau ua kom huv si. Txawm hais tias cov weldments nrog zoo weldability, vim yog cia los yog kis kab mob, oxide zaj duab xis thiab roj stains uas muaj teeb meem rau wetting tej zaum yuav tshwm sim nyob rau saum npoo ntawm weldments. Nco ntsoov tshem tawm cov yeeb yaj kiab qias neeg ua ntej vuam, txwv tsis pub cov vuam zoo tsis tuaj yeem lav.
3. Siv cov flux tsim nyog
Lub luag haujlwm ntawm cov flux yog tshem tawm cov oxide zaj duab xis ntawm qhov chaw ntawm lub vuam. Cov txheej txheem vuam sib txawv yuav tsum xaiv cov flux sib txawv. Thaum vuam precision cov khoom siv hluav taws xob xws li cov ntawv luam tawm hauv Circuit Court, txhawm rau ua kom cov vuam txhim khu kev qha thiab ruaj khov, rosin-raws li flux feem ntau yog siv.
4. Lub vuam yuav tsum tau rhuab mus rau qhov kub thiab txias
Yog hais tias qhov kub ntawm soldering yog tsawg dhau, nws tsis zoo rau kev nkag mus ntawm solder atoms, thiab nws yog tsis yooj yim sua los tsim ib tug alloy, thiab nws yog ib qho yooj yim los tsim ib tug virtual sib koom; Yog hais tias lub soldering kub yog siab dhau lawm, lub solder yuav nyob rau hauv ib tug uas tsis yog-eutectic xeev, uas yuav accelerate lub decomposition thiab volatilization ntawm flux, thiab txo qhov zoo ntawm cov solder. Nws yuav ua rau cov ntaub qhwv ntawm lub rooj tsav xwm luam tawm tuaj tawm.
5. Lub sijhawm vuam tsim nyog
Vuam lub sij hawm yog hais txog lub sij hawm xav tau rau lub cev thiab tshuaj hloov thaum lub sij hawm tag nrho cov txheej txheem vuam. Thaum qhov ntsuas kub tau txiav txim siab, lub sijhawm vuam tsim nyog yuav tsum tau txiav txim siab raws li cov duab, xwm txheej, thiab cov yam ntxwv ntawm lub workpiece yuav tsum tau welded. Yog tias lub sijhawm vuam ntev dhau lawm, cov khoom siv lossis cov khoom siv vuam yuav yooj yim puas; Yog tias nws luv dhau lawm, cov kev xav tau ntawm vuam yuav tsis raug. Feem ntau, lub sijhawm vuam ntev tshaj plaws rau txhua qhov chaw tsis ntau tshaj 5s.
