Ekiwandiiko kino kikwata ku bipimo ebikulu ebiraga omulimu gwa PTFE high-temperature tape ekozesebwa mu vacuum coating, vacuum heat treatment n’embeera ezifaananako bwe zityo. Ebyetaago ebikulu byawukana nnyo ku nkozesa y’empewo: okufulumya omukka kisinga kukulu (TML≤1%, CVCM≤0.1%; ebigezo by’omu bwengula/eby’amaaso byetaaga TML≤0.5%, CVCM≤0.01%); okuziyiza ebbugumu kulina okukakasibwa ku byombi PTFE substrate (260°C) ne adhesive layer; silikoni PSA erongooseddwa mu ngeri ey’enjawulo efulumya omukka omutono yeetaagibwa okuziyiza obucaafu bwa siloxane; amaanyi agakwata ku bbugumu erya waggulu gaziyiza okusitula n’okusitula ku mabbali; obuyonjo bwetaaga obutayiwa fiber ate nga n’obungi bwa ionic butono; anti-static tape (okuziyiza kungulu 106-109 Ω/sq) kuziyiza ESD okwonooneka; okuziyiza kwa pulasima kulina okwekenneenyezebwa ku nkola z’okufuuwa/PECVD; okukendeera kw’ebbugumu wansi wa 2% kukakasa nti masking precision.

Ekiwandiiko kino kigeraageranya okukula kw’ebbugumu ly’ekisenge n’ebbugumu eringi ery’ekyesiiga ekikwata ku puleesa ya silikoni ku ttaapu ya PTFE. Okukula mu bbugumu eringi (120-180°C) kuleeta emikutu eminene egy’omusalaba nga girina amaanyi ag’amaanyi ag’okukwatagana, okuziyiza ebisigadde eby’okusiiga oluvannyuma lw’okusekula. Ekola enkolagana ezisiba eddagala (chemical anchoring bonds) ne PTFE substrates nga ziyita mu primer co-curing, okumalawo obulabe bw’okukutuka. Okukula mu bbugumu eringi nakyo kiggyawo ebiwunya ebirina molekyu entono nga tonnazaala, ne kiziyiza okubumbulukuka n’obucaafu bwa woyiro wa silikoni mu kiseera ky’okusooka okubugumya.

Ekitabo kino kikwata ku PTFE high-temperature tape okulonda for injection molding demolding n'okukozesa anti-stick. Okulonda okusinziira ku bbugumu: ≤260°C ku buveera obw’awamu (standard silicone PSA tape, 0.13-0.18mm); 260-300°C ku buveera bwa yinginiya obw’ebbugumu eringi nga PC, PA66, POM (ekisiiga kya silikoni eky’ebbugumu erya waggulu, 0.18-0.25mm); 300-400°C ku PEEK, LCP, PPS okumpi n’abaddusi ababuguma (tepi eyesiiga eremererwa; kozesa olugoye lwa PTFE olutaliimu kwesiiga oba firimu ya PFA). Okulonda okwesigamiziddwa ku bintu: ebintu ebikwatagana (tacky materials) byetaaga high-release pure PTFE surfaces; ebintu ebijjudde endabirwamu/eby’obuggagga bw’omu ttaka byetaaga obutambi obuzitowa obwa mm 0.25+ obugumira okwambala; ebirungo ebikulukuta byetaaga ebizigo ebigumira eddagala n’ebintu ebinene; enkola ezikwata ku static zeetaaga anti-static black PTFE tape.

Olugoye lwa fiberglass olusiigiddwa PTFE lukozesebwa nnyo mu kukola emipiira olw’okugumira ebbugumu, obutakwata, n’okusikagana okutono. Ebikulu ebikozesebwa mulimu: okufulumya liners okukola plate/vacuum vulcanization n’okubumba emipiira; emisipi egitambuza ebintu egitakwata ku byuma ebiggule, kalenda, ne layini ezinyogoza; olugoye lw’okuyunga (interleave cloth) okutereka emipiira egya semifinished; okukwata mu ngeri ey’enjawulo ku silikoni ne fluoroubber; ne oven trays okusobola okuziwonya oluvannyuma. Emigaso mulimu okumalawo okunywerera kw’ekikuta, okukendeeza ku nkozesa y’ekirungo ekifulumya, okuziyiza okuzinga ebiwujjo, n’okulaba ng’okuggya ekikuta mu ngeri ennungi.

PTFE tape for eddagala payipu / ekibya anti-okukulukuta, obutakwata, n'okusiba obukuumi yeetaaga okukwatagana substrate, adhesive enkola, n'eddagala emikutu. Silicone PSA esengekeddwa okubeera 200-260°C nga erimu asidi/alkali; acrylic PSA egumira ebizimbulukusa ebiramu naye ekoma ku bbugumu okutuuka ku ≤150°C. Ku HF, okufumba >80% alkali, oba chlorine trifluoride, kozesa PTFE-only lining (tewali organic adhesive). Ekikulu: adhesive ye link esinga obunafu, so si PTFE yennyini.

PTFE tape okukwata amaanyi galongoosebwa okuyita mu kusiiga n’okuwonya enkola optimization. Okusiiga: primer layer (0.5-2μm silane primer eziyiza adhesive peeling), adhesive obuwanvu 30-60μm (optimal okukwata amaanyi), vacuum defoaming, n’okusengejja 5-10μm. Okuwonya: okubugumya mu mitendera (80-100°C okuggyawo ekizimbulukusa → 120-140°C okubumba → 150-220°C okusalasala mu buziba), oluvannyuma okuwonya (40-60°C okumala 24-48h okuwummuza situleesi), n’okutambuza okusika omuguwa okutono okuziyiza okunyigirizibwa okw’omunda okuva mu kukendeera kwa substrate. Primer yeetaagibwa nnyo ku maanyi ga PTFE aga wansi ku ngulu.

PTFE high-temperature tape ekola nga ekintu ekikulu mu kukola semiconductor, so si general-purpose consumable. Ebikulu ebikozesebwa: okukuuma ku ddaala lya wafer (plasma etching masking, CMP backside protection, CVD/PVD masking), enkola z’okupakinga (wire bonding fixation, soldering mask for PCBs), n’okuddaabiriza ebyuma (anti-static roller wrapping, cleanroom marking). Ebyetaago ebiyonjo ennyo: halogens entono (eziyiza okukulukuta kwa bond pad), siloxanes entono (<500 ppm, eziyiza okutondebwa kw’obutundutundu obuziyiza), ion z’ebyuma entono (<1 ppm buli emu), ISO Class 4 cleanroom slitting/packaging, 106-109 Ω surface resistivity, n’okufulumya TVOC entono.

Tapi ya PTFE ey’ebbugumu eringi ey’omutindo gw’obusawo egatta PTFE substrate ekwatagana n’ebiramu n’ekyesiiga kya silicone ekiwonye platinum. Ebikulu: Egoberera ISO 10993 (tewali butwa bwa cytotoxicity, sensitization, oba okunyiiga), egumira okuzaala enfunda eziwera (steam/EO/gamma), 260°C okugumira ebbugumu. Okwegendereza okukulu: tosukka 260°C (omukka ogw’obutwa ogusukka 300°C), obusannyalazo bwa gamma buyinza okuleeta okumenya, okukakasa enkola z’okuzaala, n’okusaba ebiwandiiko ebijjuvu ebikwata ku kugoberera (ISO 10993 reports, MSDS, aging data). Si kukozesa musaayi butereevu oba okuteekebwamu okuggyako nga kikakasiddwa mu ngeri ey’enjawulo.

PTFE tape okuddamu okukozesebwa kisinziira ku nsonga nnya: okukola adhesive (high crosslink density, low silicone migration, microphase structure for repositionable tack), substrate anchoring (surface activation + primer okuziyiza full adhesive transfer), backside coating (sumulula layer okukuuma adhesive nga unwinding), n'okukwata obulungi (okuyonja adhesive surface, correct peeling technique, okwewala ebbugumu erisukkiridde). Ebisiiga ebikyusiddwa ebinaabirwa mu mazzi bisobola okuddamu >90% tack oluvannyuma lw’okuyonja.

Teepu ya PTFE ey’ebbugumu erigazi yeetaaga silikoni PSA ekuuma okunywerera okuva ku -70°C okutuuka ku 260°C. Ebintu ebikulu ebikola dizayini: oluwuzi lw’enkyukakyuka olusiddwako ennanga (primer-anchored transition layer), microstructure y’ebizinga by’ennyanja (MQ resin islands + polysiloxane continuous phase), gradient crosslinking (oluwuzi olw’omunda olwa density ennene okusobola okuziyiza creep, oluwuzi olw’ebweru olwa density entono okusobola okuziyiza ebbugumu entono), n’ebijjuza ebinyweza ebbugumu (cerium oxide okuziyiza oxidation). Ebitundu bya siloxane ebikyusiddwa phenyl binyigiriza okufuuka ekiristaayo eky’ebbugumu eri wansi, ekisobozesa okukyukakyuka wansi wa -100°C.
