Koj puas paub tias qhov tsis xws luag ntawm lub rooj tsav xwm hloov tau yooj yim yuav yog? Hnub no Vility qhia qee qhov tsis xws luag thiab kev daws teeb meem rau koj.
1. Npuas yog tsim tom qab sab ntawm lub rooj tsavxwm hloov tau yooj yim los yog ib kab yog unfolded.
Lub ntsiab yog vim li cas:npuas yog tsim los ntawm ob lossis ntau kab, feem ntau vim tias txoj kab sib nrug yog nqaim thiab cov kab siab dhau lawm, ua rau nws tsis tuaj yeem luam tawm solder tiv thaiv ntawm lub substrate thaum lub sij hawm luam ntawv, ua rau qhov sib txawv ntawm cov solder thiab substrate. Tsim kom muaj huab cua lossis noo noo. Thaum lub sij hawm kho thiab raug cov txheej txheem, thermal expansion ntawm cov pa los ntawm cov pa roj yog tsuas yog tshwm sim los ntawm high hlau.
Thaum cov hniav nyob rau hauv kev sib cuag nrog cov hlau, lub kaum sab xis ntawm lub squeegee thiab cov hlau tsub kom, ua rau lub solder tiv thaiv tsis tau luam tawm rau hauv paus ntawm cov hlau lub hauv paus ntawm lub weld, thiaj li hais tias muaj roj nyob nruab nrab ntawm lub hauv paus ntawm lub weld. thiab tiv thaiv txheej ntawm cov vuam, thiab npuas yog tsim tom qab cua sov.
Kev daws:Thaum kev tshuaj ntsuam luam ntawv, nws yog ib qho tsim nyog los xyuas seb cov khoom siv tshuaj ntsuam puas tau luam tawm tag nrho ntawm sab phab ntsa ntawm lub substrate thiab kab, thiab nruj me ntsis tswj cov tam sim no thaum electroplating.
2. Saj zawg zog Circuit Court board qhov nrog kev tiv thaiv soldering thiab qauv pinholes
Lub ntsiab yog vim li cas:Lub rooj tsav xwm hloov pauv hloov tsis tau luam tawm cov ntawv nyob rau lub sijhawm thaum lub sijhawm luam ntawv txheej txheem, ua rau ntau dhau ntawm cov kua nplaum nyob hauv qhov screen, thiab cov kua nplaum seem raug xa mus rau hauv lub qhov nyob rau hauv lub siab ntawm scraper, thiab cov ntxaij vab tshaus yog me dhau lawm. Ua rau vuam tsis kam nyob rau hauv lub qhov. Cov av ntawm cov duab thaij duab hauv qab phaj, tiv thaiv lub rooj tsav xwm hloov pauv tsis pom lub teeb thaum raug, ua rau pinholes hauv cov qauv.
Kev daws:Siv high-mesh printing ntawv thiab npo phaj nyob rau hauv lub sij hawm, thiab xyuas qhov huv ntawm daim duab phaj nquag thaum raug.
3. Cov hlau nplaum tooj liab nyob rau hauv qhov kev tiv thaiv vuam txheej ntawm lub rooj tsav xwm hloov tau yooj yim qhia tau tias muaj xim dub.
Lub ntsiab yog vim li cas:Lub rooj tsavxwm hloov tau yooj yim tsis qhuav tom qab so, thiab qhov chaw ntawm lub rooj tsavxwm luam tawm yog txaws los ntawm kua lossis phau ntawv molding ua ntej luam ntawv tsis kam vuam.
Kev daws:Oxidation ntawm cov ntawv ci tooj liab ntawm ob sab ntawm cov ntawv luam tawm los ntawm kev tshuaj ntsuam luam ntawv.
Qhov saum toj no peb qhov tsis xws luag yog ib txwm, vam tias peb cov lus qhia tuaj yeem pab koj daws cov teeb meem.
