Solder Taw tes Prorrusion hais txog cov pob qij txha ntse rau ntawm cov pob qij txha ntawm lub pcb board tom qab vuam ua, uas yog hu ua soldate sument proturrusion.
Qhov kev cuam tshuam ncaj qha tshaj plaws ntawm cov sold sib koom ua ke pinching yog cov tsos ntawm pcb cov khoom. Qhov tsis tsim nyog sib txuas nrog cov khoom lag luam tuaj yeem cuam tshuam rau cov neeg siv khoom kev koom tes hauv qib tom qab; Thaum qhov ntev ntawm cov sib koom ua ke sib koom ua ke ntev dhau, nws tuaj yeem ua rau cov rwb thaiv tsev tsawg ntawm cov pob qij txha sib luag
Cov laj thawj rau PCBA hadder koom tes rub
1. Thaum phau ntawv siv vuam: qhov ntsuas kub ntawm cov tshuab hlau sib dhos yog qhov qis dhau, uas muaj peev xwm yaj tab sis tsis tuaj yeem ntub txoj kev sib koom ua ke;
Kev raug tshem tawm ntxov ntawm solding hlau tswv yim tom qab tsis tiav solidification ntawm cov cam tom qab melting kuj tseem tuaj yeem ua rau rub cov ntsiab lus;
2. Cov ntawv luam tawm PCB luam tawm yog nthuav dav mus rau cov huab cua ntev ntev, ua rau kev tsim cov pa oxides ntawm cov npoo ntawm cov yeeb yaj kiab. Thaum vuam, cov yas tsis tuaj yeem ua tiav wetted;
3. Yog tias lub sijhawm vuam ntev heev thiab flux evaporates dhau heev, nws yuav ua rau cov sib koom ua ke los ua ke.
Kev Ntsuas Txog Kev Siv Rau PCBA Solder Joy Jushing rub rub
1. Tswj qhov kub ntawm cov cam hlau rau tusyees cua sov lub tin hlau;
2. Kho lub sijhawm preheating ntawm cov cam cov hlau;
3. Time vuam thiab kev ua cov ntawv luam tawm pcb;
4. Kev tswj hwm tsim nyog hlau kub kom ntseeg tau tias Vuam zoo.
