Novices kawm rau solder circuit boards yuav tsum tau yuav hom soldering hlau
Ua ntej tshaj plaws, yog tias koj yog tub ntxhais kawm (PS: tus neeg tuaj yeem nug cov lus nug no kuj yog ib tus menyuam kawm ntawv), tsis txhob mus rau cov nqi kim rau cov pib tshiab. Yog tias koj tsis nyiam nws, tus nqi sunk yuav kuj siab. Nws tsis yog ib qho tseem ceeb uas yuav tsum tau kho qhov kub thiab txias thaum xub thawj. Txawm li cas los xij, qhov vuam ntawm lub qhov board Lub phaj kuj yuav poob. Qhov tseem ceeb yog mus yuav ib lub taub hau zoo soldering hlau. Ua ntej tshaj plaws, qhov zoo yog qhov zoo. Kuv tau pom ib co neeg soldering thiab soldering lub taub hau ib nrab melted. Qhov thib ob, rau cov pib tshiab, yog tias koj tsuas yog solder ncaj yog tias lub cuab yeej, lub qhov rooj, thiab lwm yam, tseem xav txog lub taub hau taw, lub taub hau taw yuav tsum ntse txaus. Nws yog ib qho tseem ceeb heev thiab yuav cuam tshuam rau koj cov neeg siv kev paub. Yog tias koj xav tau cov ntaub qhwv tom qab, nws raug nquahu kom siv rab riam-ntug soldering hlau taub, lossis siv lub tshuab kub kub rau tshuab thiab vuam thiab tom qab ntawd nias nws dua nrog rab riam-ntug soldering hlau. Lub sijhawm no, cov kua dej cawv rosin yog ib qho riam phom ntse. Yog tias nws yog BGA, ces tsis muaj txoj hauv kev, mus rau qhov chaw ua haujlwm kub kub tas li.
