Basic soldering txoj kev ntawm hluav taws xob soldering hlau
Ib qho, lub zog ntawm cov hlau nplaum kom txog thaum lub taub hau ntawm cov hlau soldering melts, thiab so tawm ntau tshaj solder thiab oxides ntawm daim txhuam cev ntub dej. Tuav cov hlau nplaum nrog tus cwj mem ntawm koj sab tes xis. Txav cov hlau nplaum mus rau qhov yuav tsum tau soldered thiab muab lub hau ntawm cov hlau nplaum rau ntawm lub ncoo Thaum lub sij hawm no, lub kaum sab xis ntawm lub substrate thiab hluav taws xob soldering hlau yog hais txog 40 degrees, thiab lub taub hau ntawm cov hlau solder raug thawb mus rau hauv. qhov sib txuas ntawm tus pin thiab txoj kab nqes kom yaj lub solder kom txog thaum lub solder ntws tag nrho ntub cov ntaub qhwv thiab cov hlau lead. Tshem tawm cov hlau nplaum thiab cov hluav taws xob soldering hlau kom txog thaum lub solder solidified, thiab cov kev ceev faj thaum lub sij hawm no yog raws li nram no:
1: Soldering tsis yog nyob ntawm qhov kawg ntawm lub taub hau, tab sis ntawm txoj kab nqes.
2: Lub bevel yuav tsum sib tshuam nrog tus pin thiab nyob ze rau nws.
3: Raws li qhov xwm txheej ib txwm muaj, tsis tas yuav txav lub taub ntawm cov hlau nplaum thaum ntxiv cov tin.
4: Soldering yog ua raws li cov cua sov, tsis yog los ntawm nias cov pob qij txha los ua kom cov solder.
5: Lub kaum sab xis ntawm cov hlau soldering thiab cov substrate tuaj yeem hloov kho kom ntxiv cov nyiaj ntxiv rau cov pins thiab cov ntaub qhwv. Yog hais tias lub kaum sab xis yog loj, lub solder tsis yooj yim rau infiltrate lub ncoo, tab sis tus nqi ntawm cov tin yog yooj yim los tswj, thiab solder yog yooj yim rau infiltrate yog lub kaum sab xis yog me me. Rau lub ncoo, tab sis tus nqi ntawm cov tin tsis yooj yim los tswj.
6: Tom qab soldering, yog tias muaj me ntsis solder, koj tuaj yeem rov ua dua. Ua kom cov tin ntxiv. Yog tias koj pom tias muaj ntau dhau lawm, koj tuaj yeem ua ntej so tawm cov khoom siv ntau dhau nrog lub hau ntawm cov hlau nplaum rau ntawm daim txhuam cev ntub dej, thiab tom qab ntawd rov ua cov hlau sib txuas.
7. Cov kev sib xyaw ua ke yuav tsum tau soldered kawg, thiab cov hluav taws xob soldering hlau yuav tsum tau ntseeg tau hauv av, los yog soldered nrog residual tshav kub tom qab fais fab tuag. Los yog siv lub qhov (socket) tshwj xeeb rau kev sib xyaw ua ke, thiab tom qab ntawd ntsaws cov kev sib txuas ua ke tom qab soldering lub qhov (socket). Lub hom phiaj yog los tiv thaiv cov hluav taws xob siab lossis hluav taws xob zoo li qub los ntawm kev puas tsuaj, tshwj xeeb tshaj yog cov khoom siv CMOS.
