2. Tɛmpratura Rɛsistɛns Gred

· Kɔntinyu savis tɛmpracha: Di PTFE-kɔt fayv glas sabstret fɔ PTFE tep kin tinap fɔ lɔng tɛm ɛksplɔshɔn na 260°C. Bɔt di tɛmpracha rɛsistɛns fɔ di adhesive layt fɔ verify wan tɛm. Kɔnvɛnshɔnal silikon PSA de gi kɔntinyu ɔt rɛsistɛns arawnd 200°C, we ay-pɔfɔmɛnshɔn silikon adeziv kin rich 260°C.

· Shot-tεm pik tεmprachכ: Chεk if instantaneous pik tεmprachכ dεm we dεn de prכsεs pas di tep in sכt tεm tεmεratכr limit (jεnarali ≤300°C). di tεmprachכ we pasmak go kכbכnayz εn dכn di adhesive layεr, we go mek di vεkyum chεmba bכku bכku kכntaminεshכn. Notis: If vaykum ɔt tritmɛnt tɛmpracha pas 260°C fa fawe, PTFE tep nɔ de aplay igen; polyimide (Kapton) tep ɔ aluminiɔm fɔyl tep fɔ adopt insted.

3. Adhesive Tayp & Ay-Tɛmpratura Holdin Pawa

· Adhesive system selekshɔn: Silicone prɛshɔn-sɛnsitiv adhesive na di men choice fɔ vaykum aplikeshɔn bikɔs ɔf in supiriɔr ɔt rɛsistɛns. Bɔt pan ɔl dat, ɔdinari silikon adeziv dɛn gɛt bɔku bɔku lɔw-mɔlikul silɔksan dɛn, we de volatilayz ɔnda ay-tɛmpracha vaykum ɛn kɔntamin di wokpies dɛn, mɔ di optik sɔfays ɛn ilɛktrik kɔntakt eria dɛn. So, spɛshal purifyed low-outgassing silikon adeziv ɔ nɔ-silikon adhesive fɔmyulashɔn dɛn nid.

· Ay-tɛmpracha holdin pawa: Ɔnda kɔmbayn vaykum ɛn ay-tɛmpracha kɔndishɔn, krip, edj liftin ɔ ful pil pan di tep go blɔk vaykum paip dɛn dairekt wan ɛn introduks nyu kɔntaminɛshɔn sɔs. Di shia holdin durayshɔn na ɔpreshɔn tɛmpracha fɔ validet.

4. Klin & Ayɔn Kɔntaminɛshɔn

· Klin rum kɔmpatibiliti: Di ​​tep nɔ fɔ gɛt fayv shed ɛn lint na di ed dɛn we dɛn de kɔt. Dɛn kin lɛk tep dɛn we dɛn mek na say dɛn we klin rum.

· Lɔw ayɔn kɔntinyu: Fɔ vaykum prɔses na sɛmikɔndɔkta ɛn MEMS industri, halojen ayɔn (Cl) ɛn mɛtal ayɔn (Na, K) we de insay di tep go prɛsipitayt na ay tɛmpracha, kɔrod sɔrkwit ɔ chenj doping kɔnsɛntreshɔn. Rikwest ayɔn ɛkstraktabl tɛst ripɔt frɔm di saplay dɛn.
