Qhov Kev Tshawb Nrhiav ntawm PCBA Virtual Soldering Problem Method

I. Cov laj thawj rau tiam ntawm cov khoom cuav yog

1. Solder melting point yog qhov tsawg, lub zog tsis loj.

2. Tus nqi ntawm cov tin siv hauv vuam yog tsawg heev.

3. Tsis zoo ntawm lub solder nws tus kheej.

4. Cov khoom siv pins muaj qhov tshwm sim kev ntxhov siab.

5. Cheebtsam tsim los ntawm qhov kub thiab txias tshwm sim los ntawm qhov chaw ruaj khov solder deterioration.

6. Cov khoom siv pins tsis ua haujlwm zoo thaum ntsia.

7. Tsis zoo ntawm tooj liab nto ntawm lub rooj tsav xwm Circuit Court.

Muaj ntau yam laj thawj rau tiam ntawm PCBA solder teeb meem, thiab nws kuj tseem nyuaj rau kev tswj cov txheej txheem.Dummy soldering yuav ua rau lub voj voog ua haujlwm tsis zoo, tshwm sim thaum qhov zoo thiab qhov tsis zoo, thiab ua kom nrov nrov, mus rau qhov kev ntsuam xyuas hauv Circuit Court, siv thiab saib xyuas qhov kev nyab xeeb zoo.Tsis tas li ntawd, kuj tseem muaj ib feem ntawm cov pob qij txha virtual hauv Circuit Court pib ua haujlwm rau lub sijhawm ntev, kom tswj tau qhov kev sib cuag tseem zoo, nws tsis yooj yim los nrhiav.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum muaj txoj hauv kev tshawb pom zoo kom pom cov khoom tsis zoo.

II.Kev tshawb pom ntawm PCBA cuav solder txoj kev

1. Raws li qhov tshwm sim ntawm qhov tsis ua haujlwm tshwm sim los txiav txim siab dav dav ntawm qhov tsis ua haujlwm.

2. Cov tsos ntawm kev soj ntsuam, tsom rau cov khoom loj thiab cov khoom siv nrog cov khoom siv hluav taws xob siab.

3. Magnifying iav tsom.

4. Wrenching lub Circuit Court board.

5. Tuav cov khoom tsis txaus ntseeg los ntawm tes, thaum saib seb cov pins cov pob qij txha zoo li xoob.

Tsis tas li ntawd, muaj lwm txoj hauv kev los nrhiav cov duab kos duab, siv qee lub sij hawm los ua tib zoo xyuas DC theem ntawm txhua channel tiv thaiv daim duab hluav taws xob los txiav txim qhov teeb meem yog tias tawm, uas yog nyob ntawm qhov niaj hnub tsub zuj zuj ntawm kev paub.

Dummy soldering yog ib qho kev phom sij tseem ceeb ntawm Circuit Court, dummy soldering yog ib qho yooj yim ua rau tus neeg siv tom qab lub sij hawm, tsis zoo conductivity thiab tsis ua hauj lwm, thiab tom qab ntawd ua rau tus nqi siab rov qab, nce nqi ntau lawm.Yog li ntawd, qhov teeb meem ntawm kev tsis ncaj ncees soldering yuav tsum tau pom nyob rau hauv lub sij hawm los txo qhov poob.

kev kub ceev xaiv thiab qhov chaw tshuab
