PCB yoyera ndiyofunikira kuti ikhale yodalirika. Kusindikizidwa bolodi dera nthawi zina zimatha kudziunjikira fumbi kapena zowononga zina ndipo zimafunika kutsukidwa. PCB yodetsedwa ingakhudze ntchito yoyenera ya kapangidwe kake. Kaya bolodi lanu ndi lodetsedwa chifukwa chokhudzidwa ndi malo omwe amagwirira ntchito, kapena chifukwa choyikapo kapena chitetezo chake sichikutetezedwa bwino, ndikofunikira kuchita njira zoyenera zoyeretsera kuti mukhale odalirika.

Kodi PCB yakuda imakhudza bwanji ntchito

Fumbi limakhala ndi zinthu zoimitsidwa mumlengalenga. Ndizovuta m’chilengedwe ndipo nthawi zambiri zimakhala ndi kusakaniza kwa mchere wa mchere, mchere wosungunuka m’madzi, organic zipangizo ndi madzi pang’ono.

Pamene zigawo za SMT zimakhala zazing’ono komanso zazing’ono, chiopsezo cholephera chifukwa cha zonyansa chimawonjezeka. Kafukufuku wasonyeza kuti fumbi limapangitsa kuti matabwa ozungulira azitha kulephera chifukwa cha chinyezi, monga kutayika kwa kutentha kwa pamwamba, kusamuka kwa electrochemical, ndi dzimbiri.

Momwe mungayeretsere PCB

Chisamaliro chowonjezera chiyenera kutengedwa poyeretsa PCB. Njira zodzitetezera za ESD ziyenera kuganiziridwa ndipo ziyenera kudulidwa ndikuchitidwa pamalo owuma. Ngati mugwiritsa ntchito njira zoyeretsera zolakwika kapena njira, bolodi silingagwire ntchito konse.

Sambani fumbi

Kwa fumbi, njira yabwino yochotsera fumbi ndikuwomba gulu lozungulira ndi mpweya wothinikizidwa. Samalani ndi madera ovuta omwe angayambitse kuwonongeka. Mswachi ndi chida china chomwe mungagwiritse ntchito pochotsa fumbi.

Kutuluka koyera

Ma board ozungulira okhala ndi AIDS yotsalira ayenera kutsukidwa ndi mankhwala a saponifying. Kwa amateurs ndi mainjiniya, ndizofala kwambiri kupukuta vinyo. Msuwachi ukhoza kunyowetsedwa ndi mowa ndipo ukhoza kugwiritsidwa ntchito kutsuka kuphulika kulikonse. Chonde dziwani kuti ngati ma welds anu a board alibe flux osasamba, zimakhala zovuta kuchotsa ndipo chotsukira champhamvu chingafunike.

Chotsani dzimbiri

Gwiritsani ntchito soda kuti muchotse dzimbiri zazing’ono zomwe zimayambitsidwa ndi mabatire ndi zinthu zina. Itha kugwiritsidwa ntchito kuchotsa dothi popanda kuwononga bolodi. Soda wothira ndi abrasive pang’ono ndipo amathandiza kuchotsa dzimbiri kapena zotsalira zomwe sizikanatheka ndi zida zosavuta monga burashi ndi madzi osungunuka. Komanso neutralizes acidity ya zotsalira.
