Cov ntsiab lus ua haujlwm ntawm cov khoom siv yoj soldering

Cov ntsiab lus ua haujlwm ntawm cov khoom siv yoj soldering
1. Soldering kub ntawm yoj soldering khoom

Qhov ntsuas kub ntawm cov khoom siv yoj soldering yog hais txog qhov kub ntawm cov cuab yeej siv hluav taws xob siab kawg ntawm lub qhov hluav taws xob nozzle.Feem ntau, qhov kub thiab txias yog 230-250 ℃, thiab yog tias qhov kub thiab txias tsis dhau, cov pob qij txha yog ntxhib, rub thiab tsis ci.Nws txawm ua rau vuam virtual thiab tsis tseeb incandescence;Yog tias qhov kub thiab txias dhau lawm, nws yooj yim rau kev ua kom oxidation, deform lub rooj tsav xwm luam tawm, thiab hlawv tag nrho cov khoom.Kev kho qhov kub thiab txias yuav tsum tau kho raws li cov khoom siv thiab qhov loj ntawm cov ntawv luam tawm, qhov kub thiab txias, thiab qhov ceev ntawm txoj siv conveyor.

2. Tshem cov tin slag nyob rau hauv lub yoj soldering rauv raws sij hawm

Lub tin nyob rau hauv lub tin da dej ntawm cov khoom siv yoj yoj yuav ua rau oxides thaum nws nyob rau hauv kev sib cuag nrog huab cua ntev.Yog tias cov oxides sib sau ntau dhau lawm, lawv yuav raug txau rau ntawm cov ntawv luam tawm nrog cov tin nyob rau hauv qhov kev txiav txim ntawm lub twj tso kua mis.Me ntsis solder pob qij txha nyob rau hauv lub luster.Ua rau muaj qhov tsis xws luag xws li slag tswj thiab txuas txuas.Yog li ntawd, nws yog ib qho tsim nyog los tshem tawm cov oxides tsis tu ncua (feem ntau txhua 4 teev).Antioxidants kuj tuaj yeem muab ntxiv rau lub molten solder.Qhov no tsis tsuas yog tiv thaiv oxidation tab sis kuj txo cov oxide rau tin.

3. Qhov siab ntawm yoj crest ntawm cov khoom siv yoj soldering

Lub yoj qhov siab ntawm cov khoom siv yoj soldering yog qhov zoo tshaj plaws kho rau 1/2-1/3 ntawm lub thickness ntawm cov ntawv luam tawm.Yog hais tias lub yoj crest tsawg dhau, nws yuav ua rau solder to thiab tin dai, thiab yog tias yoj crest siab dhau lawm, nws yuav ua rau tin piling ntau dhau.Cov khoom kub heev.

4. Kev sib kis ceev ntawm cov khoom siv yoj soldering

Kev sib kis ceev ntawm cov khoom siv yoj soldering feem ntau tswj ntawm 0.3-1.2m / s.Txiav txim siab raws li qhov xwm txheej.Nyob rau lub caij ntuj no, thaum lub rooj tsav xwm luam tawm muaj cov kab dav dav, ntau yam khoom, thiab cov khoom siv hluav taws xob loj ntawm cov khoom.Qhov ceev tuaj yeem qeeb me ntsis;rov qab ceev tuaj yeem ceev dua.Yog tias qhov nrawm nrawm dhau, lub sijhawm vuam luv dhau.Nws yog ib qho yooj yim uas yuav ua rau lub phenomenon ntawm lub tsev welding, cuav welding, uas ploj lawm vuam, bridging, huab cua npuas, thiab lwm yam .;qhov ceev yog qeeb heev.Lub sijhawm vuam ntev dhau lawm thiab qhov kub thiab txias siab dhau.Yooj yim puas luam Circuit Court boards thiab cov khoom.

5. Lub kaum sab xis ntawm cov khoom siv yoj soldering

Lub kaum sab xis ntawm cov khoom siv yoj soldering feem ntau xaiv ntawm 5-8 degrees.Nws yog txiav txim siab los ntawm thaj tsam ntawm lub rooj tsav xwm luam tawm thiab cov khoom siv uas tau muab tso rau.

6. Kev soj ntsuam ntawm cov tin muaj pes tsawg leeg nyob rau hauv yoj soldering da dej

Kev siv cov khoom siv hauv cov tin da dej ntawm cov khoom siv yoj soldering yog hu ua tom qab.Nws yuav ua rau kom cov impurities nyob rau hauv yoj soldering hlau lead solder, feem ntau tooj liab ion impurities cuam tshuam rau vuam zoo.Feem ntau, nws yuav siv sij hawm 3 lub hlis rau kev soj ntsuam kuaj - lub sij hawm.Yog tias impurities tshaj cov ntsiab lus tso cai, yuav tsum ntsuas los hloov lawv.
