Yuav ua li cas solder hlau nrog ib tug soldering hlau
1. Clamp daim tawv nqaij ntawm cov hlau nrog pliers thiab tev tawm me ntsis. Nco ntsoov tsis txhob hlais ntau dhau thaum stripping cov hlau, tsuav yog me ntsis ntau tshaj qhov hla ntawm cov hlau, ces ntswj lub stripped hlau kawg, txwv tsis pub nws yuav raug welded tawm muaj spikes uas tuaj yeem puncture daim kab xev lossis cua sov shrink tubing. ;
2. Muab cov xov tshem tawm hauv vuam cov roj los yog rosin, tsis txhob poob ntau dhau, me ntsis, kom nws zoo dua rau vuam thaum vuam;
3. Muab ib co solder rau ntawm txhua lub xov hlau kawg, kom nws yooj yim rau lo thaum soldering cov xov hlau ua ke. Tom qab tinning, thov ib tug me ntsis roj solder, thiab muab ib co solder rau ntawm cov hlau soldering. Ua tib zoo saib yuav ua li cas cov hlau thiab cov xov yog pinched los ntawm tes. Lub caj npab tuav cov xov yuav tsum muaj qhov taw tes txhawb nqa, txwv tsis pub txhais tes yuav co ib txwm;
4. Siv ob tug ntiv tes no los tuav ib qho ntawm cov xov, thiab tom qab ntawd siv ob tus ntiv tes txhawm rau txhawm rau lwm cov xov, stagger qhov kawg ntawm cov xov thiab khaws cia ua ke;
5. Nyob rau hauv cov kauj ruam no, maj mam lean lub soldering hlau tshaj. Tom qab lub solder ntawm txoj kab melts, lawv yuav cia li welded ua ke, thiab ces tshem tawm cov soldering hlau;
6. Lub ntsiab lus kawg uas yuav tsum tau ua tib zoo saib yog tias txhais tes tuav cov hlau yuav tsum tsis txhob co, txwv tsis pub lub solder yuav tsis txias txaus, thiab tes yuav co thiab solder yuav tsis muaj zog.
Soldering hlau, yam welding
Cov hluav taws xob soldering hlau belongs rau phau ntawv vuam;
Cov txheej txheem-raws li soldering suav nrog SMT (chip batch soldering) thiab yoj soldering (plug-in batch soldering).
Cov hluav taws xob soldering hlau tuaj yeem ua manually solder lub thaj los yog lub plug-in.
Tam sim no siv lead-free solder yog siv. Muaj ob feem ntau siv tin-nyiaj-tooj alloys thiab tin-tooj liab alloys, thiab lub melting point yuav tsum siab tshaj 220;
Kev tuav vuam kub feem ntau yog 320-390 degrees hauv lub caij ntuj sov thiab 350-400 degrees hauv lub caij ntuj no;
Yog tias qhov ntsuas kub tsawg dhau, qhov vuam yuav tsis du, thiab qhov kub thiab txias tuaj yeem tsim nyog nce lossis txo raws li cov khoom siv vuam.
