Yuav ua li cas tiv thaiv rau qhov tshwm sim ntawm tin sib txuas ntawm Circuit Court board tom qab yoj soldering.

1. Vim yog qhov tshwm sim ntawm cov hlau sib txuas ua rau ntev dhau los tiv thaiv tus pin thaum nthwv dej soldering ntawm Circuit board, yuav tsum tau them nyiaj rau qhov txuas txuas ntxiv ntawm tus tiv thaiv tus pin feem ntau 1.5-2mm, uas yuav tsis tshwm sim yog tias nws tsis siab tshaj qhov siab no .

2. Vim tias txheej txheem PCB txheej txheem tsim ntau thiab ntau dua thiab cov hlau lead sib nrug tau ntau dua thiab ntom ntom ntom ntom, qhov tshwm sim ntawm cov hlau txuas tom qab yoj yoj yoj tshwm sim. Hloov lub ncoo tsim yog qhov kev daws teeb meem. Piv txwv li, txo qhov ncoo me me, nce qhov ntev ntawm lub ncoo tawm ntawm lub nthwv dej sab, ua kom cov dej ntws tawm ntau ntxiv / txo cov hmoov txhuas txuas ntxiv ntev kuj yog cov kev daws teeb meem.

3. Tom qab nthwv dej soldering, cov yaj yaj yaj yaj tau nkag mus rau saum npoo ntawm lub rooj tsav xwm hauv Circuit kom tsim cov tin txuas ntawm cov khoom sib txuas. Qhov laj thawj tseem ceeb rau qhov tshwm sim no yog tias sab hauv txoj kab uas hla ntawm lub khoob khoob loj dhau, lossis sab nrauv ntawm tus pin ntawm cov khoom tiv thaiv me me.

4. Lub pob zeb nthwv dej tsim los ntawm cov khoom sib thooj taw hauv ob thaj chaw txuas nrog tin tom qab vuam.

5. Wave soldering nrog tin vim muaj cov ntaub qhwv ntau dhau.

6. Tin txuas ntawm cov pins tiv thaiv tom qab yoj yoj yoj vim tsis zoo solderability ntawm tiv thaiv pins.

Txoj hauv kev tiv thaiv tin kev sib txuas ntawm Circuit board tom qab yoj yoj yoj.

1. Tsim raws li PCB tsim tshwj xeeb. Lub axis ntev ntawm ob daim kawg yuav tsum yog txoj kab ncaj nraim rau txoj kev siv vuam, thiab lub axis ntev ntawm SOT thiab SOP yuav tsum yog sib npaug rau qhov vuam qhia. Qhib lub ncoo ntawm tus pin kawg ntawm SOP (tsim daim kab xev);

2. Cov pins ntawm cov khoom siv tso rau hauv yuav tsum tsim raws li qhov sib nrug ntawm qhov sib dhos thiab qhov xav tau los ua ke ntawm daim ntawv luam tawm. Yog tias cov txheej txheem vuam vuam luv tau txais yuav, cov pins tiv thaiv ntawm qhov vuam nto yuav tsum tau nthuav tawm rau saum npoo ntawm cov ntawv luam tawm los ntawm 0.8 ~ 3mm, thiab lub cev tivthaiv yuav tsum ncaj thaum lub sijhawm nkag;

3. Teeb tsa qhov ntsuas kub ua ntej raws li PCB qhov loj me, seb puas muaj cov laug cam ntau txheej, tus naj npawb ntawm cov khoom siv, tus naj npawb ntawm cov khoom sib txuas, thiab lwm yam;

4. Cov cua kub yoj kub yog 250 ± 5 ℃, thiab lub sijhawm siv vuam yog 3 ~ 5S. Thaum qhov kub tau qis dua me ntsis, qhov nrawm ntawm txoj siv thauj khoom yuav tsum qeeb dua;

5. Hloov cov dej ntws.
