Haanta Kaydka ee PTFE ee safan ee Cu Etchant

RANA's PTFE ee dahaadhka naxaasta etching wakiilka haanta kaydinta waxay isticmaashaa tignoolajiyada dahaarka PTFE, ee loogu wanagsan yahay sifada wakiilada etching copper (kuwaaso ka kooban qaybo daxalaysan sida nitric acid, hydrochloric acid, ama wakiilada isku dhafan). Si loo xaqiijiyo natiijooyinka etching ugu fiican, wakiilka naxaasta etching waa inuu ilaaliyaa saamiga ka kooban xasilloon. Xasiloonida kiimikaad ee PTFE waxay ka hortagtaa walaxda inay soo baxdo, taas oo faragelin karta samaynta wakiilka etching oo iska caabin kara daxalka haanta. Darbiga gudaha ee siman ee haanta waxa uu yareeyaa hadhaaga wakiilka etching waxana uu yareeyaa halista iskutallaabtu{3}} faddarayn inta lagu jiro buuxinta.

Haanta kaydinta waxaa ugu horayn loo isticmaalaa soo saarida looxyada elektiroonigga ah (PCBs) iyo looxyada xudunta u ah semiconductor. Daxalkeeda{1} adkaysi u leh iyo heerkulku{2} guryaha adkaysi u leh waxay u ogoladaan inay buuxiso shuruudaha kaydinta wakiilada etching heerkul kala duwan, sida heerkulka deegaanka ama ku dhawaad ​​​​50 darajo kululaynta etching. Intaa waxaa dheer, taangiga waxaa lagu qalabeeyay heerka dareeraha iyo isku xirka la socodka, taasoo awood u siinaya la socodka dhabta ah-waqtiga la socodka heerka wakiilka etching, hubinta saxnaanta etching iyo dhalida looxa wareegyada ama looxa xudunta u ah.
