Chifukwa plating, zikusonyeza kuti youma filimu ndi mkuwa zojambulazo mbale kugwirizana si amphamvu, kotero kuti plating njira kwambiri, chifukwa mu "gawo zoipa" mbali ya ❖ kuyanika thickening, ambiri opanga PCB amayamba ndi zifukwa zotsatirazi. :

1. Mphamvu yapamwamba kapena yochepa

Pansi pa kuwala kwa ultraviolet, photoinitiator, yomwe imatenga mphamvu ya kuwala, imasweka kukhala ma radicals aulere kuti ayambitse photopolymerization ya ma monomers, kupanga mamolekyu amthupi osasungunuka mu njira ya alkali.
Pansi pa kukhudzana, chifukwa chosakwanira polymerization, pa chitukuko ndondomeko, filimu kutupa ndi kufewetsa, chifukwa mizere yosadziwika ngakhale filimu wosanjikiza kutali, chifukwa osauka kuphatikiza filimu ndi mkuwa;
Ngati kukhudzana ndi kwambiri, zidzachititsa mavuto chitukuko, komanso mu ndondomeko electroplating adzabala zopindika peel, mapangidwe plating.
Choncho ndikofunika kulamulira mphamvu yowonetsera.

2. Kuthamanga kwa mafilimu apamwamba kapena otsika

Pamene kupanikizika kwa filimu kumakhala kochepa kwambiri, filimuyo imakhala yosagwirizana kapena kusiyana pakati pa filimu yowuma ndi mbale yamkuwa sikungakwaniritse zofunikira za mphamvu yomangiriza;
Ngati filimu kuthamanga kwambiri, zosungunulira ndi kosakhazikika zigawo zikuluzikulu za dzimbiri kukana wosanjikiza kwambiri kosakhazikika, chifukwa youma filimu kukhala Chimaona, electroplating mantha adzakhala peeling.

3. Kutentha kwapamwamba kapena kochepa kwa filimu

Ngati filimu kutentha ndi otsika kwambiri, chifukwa dzimbiri kukana filimu sangathe mokwanira anafewetsa ndi otaya yoyenera, chifukwa mu youma filimu ndi mkuwa atavala laminate pamwamba adhesion osauka;
Ngati kutentha kwambiri chifukwa cha mofulumira evaporation wa zosungunulira ndi zina kosakhazikika zinthu mu dzimbiri kukana kuwira, ndi youma filimu amakhala Chimaona, mu electroplating mantha mapangidwe warping peel, chifukwa mu percolation.
