- Txheeb xyuas PCB tsim:Tshawb xyuas PCB tsim rau txhua yam teeb meem ntsig txog kev teeb tsa hauv Circuit Court, tsis txaus qhov sib nrug, lossis tsis raug. Kho qhov tsim kom tsis txhob muaj teeb meem qhib Circuit Court.

- Ua ib qho kev xeem txuas ntxiv:Siv lub multimeter txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam. Tsom ntsoov rau thaj chaw cuam tshuam thiab rov ua dua cov kev sib txuas no raws li xav tau.

2. Component Misalignment: Phau ntawv qhia daws teeb meem

Kev sib raug zoo lossis qhov sib nrug ntawm cov khoom tuaj yeem ua rau kev tsim khoom tsis zoo thiab cov khoom siv hluav taws xob tsis ua haujlwm. Nov yog qee cov tswv yim tswv yim los daws cov teeb meem misalignment:

- Ua ib qho kev ntsuam xyuas pom:Tshawb xyuas tag nrho PCB los ua ke thiab xyuas qhov kev tso kawm thiab kev ua kom zoo ntawm txhua qhov khoom. Saib rau tej yam khoom uas khoov, kov qhov chaw uas nyob ib sab, los yog qhov chaw tsis raug. Kho lawv ua tib zoo siv cov cuab yeej tsim nyog.

- Txheeb xyuas cov khoom specifications:Tshawb xyuas cov ntaub ntawv thiab cov ntsiab lus tshwj xeeb kom paub meej qhov tseeb thiab kev taw qhia thaum sib dhos. Kev ntxig cov khoom tsis raug tuaj yeem ua rau muaj teeb meem ua haujlwm.

- Siv cov jigs thiab fixtures:Kev siv cov jigs, fixtures thiab templates tuaj yeem txhim kho qhov tseeb thiab sib xws hauv cov khoom tso. Cov cuab yeej no pab kho kom haum thiab ruaj ntseg cov khoom hauv txoj hauj lwm kom raug, txo qhov muaj peev xwm ntawm misalignment.

3. Welding teeb meem: daws teeb meem ntau yam tsis xws luag

Soldering teeb meem tuaj yeem cuam tshuam rau kev ua haujlwm thiab kev ntseeg siab ntawm Circuit Board soldering. Cia peb tshawb txog qee qhov tsis xws luag thiab cov lus qhia txog kev daws teeb meem:

- Disturbed solder pob qij txha:Qhov no tshwm sim thaum qhov kev sib txuas ntawm soldered cuam tshuam thaum lub caij txias. Txhawm rau tiv thaiv kev cuam tshuam nrog kev sib koom ua ke, xyuas kom tseeb tias cov khoom siv thiab PCB tseem nyob tom qab soldering kom txog thaum lub solder tau txias tag thiab solidified.

- Cold welding:Qhov chaw vuam txias yog tshwm sim los ntawm cov cua sov tsis txaus thaum lub sij hawm vuam txheej txheem. Lub solder yuav tsis khi kom zoo, ua rau tsis zoo hluav taws xob thiab cov khoom siv sib txuas. Siv cov cua sov kom txaus thaum lub sij hawm soldering thiab xyuas kom meej tias cov solder ntws zoo, npog cov khoom siv lead ua thiab cov ntaub qhwv.

- Solder bridging:Solder bridging tshwm sim thaum ntau tshaj solder tsim ib qho kev sib txuas ntawm ob tus pins uas nyob ib sab lossis cov ntaub qhwv. Ua tib zoo xyuas txhua qhov sib koom ua ke thiab tshem tawm cov khoom siv ntau dhau nrog cov cuab yeej desoldering lossis cov xaim hlau. Xyuas kom tseeb tias muaj kev tshem tawm kom raug ntawm cov pins thiab cov ntaub qhwv los tiv thaiv kev txuas yav tom ntej.

- Pad puas:Overheating thaum lub sij hawm soldering tuaj yeem ua rau cov PCB puas, cuam tshuam rau kev sib txuas hluav taws xob. Ua kom ceev faj kom tsis txhob raug cov ntaub qhwv mus ntev rau qhov kub siab.

4. Tib neeg yuam kev: Tiv thaiv vuam yuam kev

Txawm hais tias muaj kev nce qib hauv automation, tib neeg kev ua yuam kev tseem yog ib qho tseem ceeb ntawm kev vuam tsis xws luag. Nov yog qee qhov kev ceev faj kom txo qhov yuam kev:
