1. Cacisa izidingo: khetha uhlobo olukwazi ukumelana nokushisa ({1}}njenge-fluorosilicone) yendawo yokushisa ephezulu, futhi unake ileveli yokwahlukanisa emkhakheni we-electronics.
2. Ukuqhathaniswa kwepharamitha: iphutha logqinsi kufanele libe Ngaphansi noma lilingane no-±0.05mm, futhi impilo yamashidi e-silicone yezinga lezimboni-ngokuvamile iminyaka engu-5-8 (umthombo wedatha: I-China Rubber Industry Association).
3. Amazinga wokuqinisekisa: Isitifiketi se-FDA siyadingeka ukuze kusetshenziselwe ukwelashwa, futhi ukuhlolwa kwe-UL94 kwe-flame retardant kuyadingeka embonini yezimoto.
