Kev ua haujlwm tsis zoo ntawm yoj soldering yuav ua rau muaj kev sib tsoo PCB solder pob qij txha yuav luv luv-circuited thiab tinned. Luv-circuiting ntawm PCB solder pob qij txha nrog tin kuj yog feem ntau soldering tsis ua hauj lwm ntawm manufacturers nyob rau hauv yoj soldering. Nws tshwm sim los ntawm ntau yam. Cia peb tsom xam nrog koj cov laj thawj vim li cas lub rooj tsav xwm PCB luv luv thiab tinned tom qab yoj soldering.

1. Cov kua tin tsis tau mus txog qhov kub thiab txias ua haujlwm, thiab muaj “tin hlau” choj ntawm cov pob qij txha.

2. Kev taw qhia ntawm lub substrate tsis zoo sib xws nrog tin yoj. Hloov cov kev taw qhia ntawm lub tin.

3. Kev tsim hluav taws xob tsis zoo: Cov kab hluav taws xob lossis cov kev sib txuas yog ze dhau (yuav tsum muaj qhov deb ntawm ntau tshaj 0.6mm); Yog tias lawv tau npaj cov pob qij txha los yog ICs, koj yuav tsum xav txog kev nyiag cov ntaub qhwv los yog siv cov xim dawb los cais lawv. Lub thickness ntawm cov xim dawb yuav tsum yog ntau tshaj ob npaug ntawm cov tuab ntawm cov ntaub qhwv (kub txoj kev).

4. Cov tin uas muaj kab mob los yog cov oxides ntau dhau los ntawm PUMP tuaj yeem ua rau luv luv. Lub tin cub yuav tsum tau muab ntxuav los yog lub solder nyob rau hauv lub tin da dej yuav tsum tau renewed kiag li.

5. Lub tin tas mus li yuav tshwm sim los ntawm qhov kub tsis txaus ua ntej ua rau cov txheej txheem tiv thaiv kom ncav cuag qhov kub thiab txias. Thaum lub sij hawm soldering txheej txheem, vim lub tshav kub nqus ntawm cov tivthaiv, nws yuav ua rau tsis zoo tin dragging thiab daim ntawv nruam tin; nws kuj yuav yog qhov kub ntawm lub cub tawg yog qhov tsawg, lossis qhov vuam ceev nrawm dhau.

Los ntawm cov saum toj no tsib lub ntsiab lus tsom xam, nws yuav tsum muaj peev xwm nrhiav tau qhov laj thawj yog vim li cas lub PCB board yog luv luv-circuited thiab tinned tom qab yoj soldering. Yog hais tias qhov saum toj no tsib-point kev tshawb fawb tseem nrhiav tsis tau vim li cas, nws yog tej zaum qhov teeb meem yoj soldering. Piv txwv li, qhov ntsuas kub thiab qhov tseeb qhov kub ntawm yoj soldering yog txawv.
