PTFE kasɛti min bɛ funteni caman sɔrɔ FPC Hot Press Lamination Defect Prevention kama

I n’a fɔ PTFE kaseti dilannikɛla ŋana, Jiangsu Aokai New Materials bɛ ɲɛfɔli caman di aw ma. Flexible Printed Circuit Boards (FPC) ka presse hot press lamination processus kɔnɔ, PTFE kaseti funteni caman bɛ fiɲɛba fila ɲɛnabɔ — substrat wrinkling ani adhesive transfer — ni fɛnw ye minnu bɛ sɔrɔ u yɛrɛ la (surface energy low, high dimensional stability) ani baarakɛcogo ɲumanw (stacking structure design, parameter control). A bɛ kɛ i n’a fɔ isolation layer saniyalen ɲuman  ani pressure equalizing buffer layer.

I. Substrat kurukuruni ni nɔrɔli sababuw

Substrate Wrinkling A sababu ju bɛ funteni ni degun tilatilali tɛ kelen ye. FPC bɛ kɛ ni fɛn caman ye i n’a fɔ PI filimu, nɛgɛso ani nɛgɛw minnu ka coefficients d’expansion thermal (CTE) tɛ kelen ye. Ka fara o kan, kafoda dilancogo fɛnw i n’a fɔ nɛgɛ janya tɛ kelen ye ani a gɛlɛyali senw bɛna kɛ sababu ye ka degun tilatilali kɛ cogo kelen na. Funteni ni degun tɛ kelen ye, o bɛ kɔnɔnafɛnw degun bila mɔgɔ la, o bɛ na ni kurukuru, kurukuruni ani delamination ye.

Adhesive Transfer (Adhesive Residual) O bɛ sɔrɔ kɛrɛnkɛrɛnnenya la ni ɲɔgɔndan ni fɛnw tiɲɛni ye. Datugulan filimu min bɛ kɛ lamini na, o nɔrɔlen tilayɔrɔba kɛnɛyalen bɛ wuli ka woyo funteni caman na, wa a bɛ nɔrɔ isolation fɛnw sanfɛ. O waati kelen na, ni silikɔni tansiyɔn sɛgɛsɛgɛlikɛlan min datugulen don PTFE kaseti kɔfɛ, ni funteni kunbɛncogo tɛ se ka kɛ walima ni a kɛcogo paramɛtiriw tɛ bɛn, jɛɲɔgɔnya dɛsɛ bɛna kɛ funteni caman na, o bɛ kɛ sababu ye ka nɔrɔlan yɔrɔ dɔ bila FPC sanfɛ.

Thermal shock isolation & uniform pressure distribution Stacking structure standard kɔnɔ: Plaque chaude → PTFE kase → silicone cushion → FPC → PTFE kase → Hot plate , PTFE kase bɛ baara kɛ i n’a fɔ bɔli layɛrɛ. A ka funteni-taama sabatili bɛ funteni-taama cogo kelen na. Ni a bɛ jɛ ka baara kɛ ni silikoni tamponw ye, a bɛ degunw lajɔ minnu bɛ sɔrɔ diferential thermal expansion fɛ ani ka degun bɛɛ lajɛlen balansi, ka sigida degunw hakɛ ni kurukuru kɔfɛtaw bali. Walasa ka fɛn dilanni kɛ ka ɲɛ, PTFE kase min barika ka bon ni galasi ye, ni CTE ka dɔgɔn, o bɛ fɔ walasa ka a hakɛ sabatili ɲuman sɔrɔ.

Stable thermal processing window PTFE layɛrɛ bɛ funteni jiginni tilennen bali. Ni a farala silikoni kuranw ka funteni-hystérese kan, funteni-taama bɛ kɛ nɔgɔya ye ani ka sabati. A bɛ danfara min bɛ jirisunw ni ɲɔgɔn cɛ funteni danfara la ≤ 5~7 °C kɔnɔ nɔrɔlen jeli waati, o bɛ kɛ sababu ye ka fiɲɛ bɔli dafalen kɛ sani nɔrɔlen ka kɛnɛya sabatilen, ani ka kurukuruw ban kosɛbɛ minnu bɛ sɔrɔ jeli kɛli ka kɔn a waati ɲɛ ani a bɔli kɔfɛ. Funteni jiginni yɔrɔba funteni hakɛ ka kan ka kɔlɔsi ni 4,5~5,0 °C/min ye.

Adhesive Transfer (Adhesive Transfert) bɔli

Nafolo min tɛ nɔrɔ ni sanfɛla fanga dɔgɔyalenba ye PTFE bɛ sanfɛla fanga dɔgɔya kosɛbɛ (18 mN/m) jira, o ka dɔgɔ kosɛbɛ ka tɛmɛ resin ni nɔrɔlenw ta kan. Ni a kɛcogo ɲumanba don min tɛ nɔrɔ, i n’a fɔ tobilikɛminɛn minnu tɛ nɔrɔ, a bɛ se ka bɔ nɔgɔya la lamini kɔfɛ k’a sɔrɔ a ma FPC substrates sɔgɔsɔgɔ walima ka kola tolen to.

Nɔrɔlan min bɛ baara kɛ kosɛbɛ, o sugandili Walasa ka a yɛrɛ tanga kaseti jiginni ma, PTFE kase min dilannen don ni nɔrɔlan ɲuman ye min bɛ se ka silikɔni degun, o ka kan ka ta. Silikoni nɔrɔlan ɲuman bɛ baara sabatili sabati fo ka se 260 °C ma, o bɛ a to zeru tolen tɛ kola la ni a dilanni tɛ ban waati jan kɔnɔ. Funteni kunbɛnni hakɛ ka kan ka baarakɛcogo wajibiyalenw dafa ka ɲɛ (210–260 °C).

Nɛgɛw kɛnɛyali dafalen Aokai PTFE kaseti dacogo n’a dilanni senfɛ, kɛnɛyali waati, funteni walima boli teliya min tɛ bɛn, o bɛna kɛ sababu ye ka nɔrɔlenw kɛnɛyali dafa, o bɛ dɔ fara nɔrɔli tolenw gɛlɛyaw kan a kɛli kɔfɛ.
