① Tepi yotentha kwambiri ya pet ndi yoyenera kuchitira zitsulo pamwamba pazitsulo monga makina a makompyuta ndi makabati, ufa wotentha kwambiri supopera, ndipo utoto wophika umagwiritsidwa ntchito poteteza;
② pet kutentha tepi ndi oyeneranso kutchinga chitetezo ndi kutchinjiriza pa kutentha kupopera mankhwala pakompyuta, makampani magalimoto, ❖ kuyanika ndi zinthu zina;
③ Amagwiritsidwa ntchito pokonza matabwa osindikizidwa, zida zamagetsi, zopinga ndi ma capacitors panthawi yopanga ndikutchinjiriza gawo la chala chagolide panthawi ya PCB board ndikuletsa kumizidwa ndi kuipitsidwa kwa njira ya electroplating, komanso kuteteza zosindikizidwa. bolodi lozungulira ndi golide;
④Zida zam'nyumba, makina, zamagetsi ndi mafakitale ena amafunikira kupenta ndi kupopera mbewu mankhwalawa, ndipo tepi yotentha kwambiri ya ziweto imagwira ntchito yomanga ndi kukonza.
