PTFE High-Temperature Tape ka Adhesive Residue & Adhesive Bleed bali cogo min na ni aw bɛ PCB Sanu bolokɔninw lakana SMT Mounting kɔnɔ

Jiangsu Aokai New Materials, n’o ye PTFE kaseti dilannikɛla ŋana ye, o bɛ baarakɛlaw bilasirali kɛ. Ni PTFE kaseti funteni caman bɛ kɛ ka PCB sanu bolokɔniw lakana SMT lajɛ waati, nɔrɔlen tolenw (fɛn nɔrɔlenw minnu bɛ to sanu bolokɔninw kan kaseti bɔlen kɔfɛ) ani nɔrɔlen joli (nɔrɔli bɛ nɔgɔya ani ka fa funteni caman na, ka yɔrɔw nɔgɔ minnu ma lakana walima PCB yɔrɔw) relow soldering kɔfɛ, olu bɛ sɔrɔ kosɛbɛ kaseti sugandili jugu fɛ walima a bɛnbaliya fɛ taabolo paramɛtɛrɛw. Fɛnɲɛnɛmafagalanw sigilen bɛ duguma:

I. Adhesive Residue & Bleed ka sababu juguw sɛgɛsɛgɛli

1. Nɔrɔlan tolen  A bɛ kɛ ni nɔrɔlan ye cohesive failure (nɔgɔlan kɔnɔna tigɛtigɛ) walima ni interfacial transfer failure (nɔrɔli bɛ bɔ substrat la ka nɔrɔ sanu bolokɔninw na). Fɛn minnu ka teli ka a bila mɔgɔ la, olu ye kaseti ka funteni kunbɛnbaliya ye, nɔrɔlan kɔrɔlen, walima a bɔli waati bɛnbali.

2. Adhesive Bleed  Adhesive ka sɔgɔsɔgɔninjɛ bɛ jigin kosɛbɛ ni reflow funteni ka bon, o bɛ na ni ji bɔli ye kosɛbɛ. Lamini tansiyɔn ni kapilɛri wale kɔrɔ, nɔrɔlan bɛ kaseti da fa. A ka c’a la, o bɛ sɔrɔ nɔrɔmugumugu dacogo jugumanba fɛ, funteni jiginni teliya la, walima nɛgɛdaga yɛrɛ ka funteni jiginni juguya fɛ.

II. Kasɛti sugandili ɲuman – Furakɛcogo koloma

PTFE kasɛti gansan tɛ se ka SMT taabolo ka ɲinini dantɛmɛnenw dafa. Fɛn minnu dabɔra kɛrɛnkɛrɛnnenya la SMT sanu bolokɔniw lakanani kama, olu ka kan ka sugandi, ni fɔlɔ ye ka ɲɛsin nɔrɔlenw ka baarakɛcogo ma:

 

· Funteni kunbɛnni hakɛ : Funteni hakɛ kuntaala surun ≥ 300°C, baarakɛcogo funteni min bɛ to senna ≥ 260°C, o ka ca ni soldering reflow ye min tɛ plɔmu sɔrɔ (245–250°C).

· Adhesive Layer Thickness : Ni a janya ka bon, o tɛ bɛn nɔrɔli barikama ma. Aw bɛ kaseti minnu ka fisa ni u bɛɛ janya ye milimɛtɛrɛ 0,08–0,13 ye, minnu bɛ kɛ ni nɔrɔlan finmanw ye nka u bɛ ɲɔgɔn minɛ kosɛbɛ walasa ka joli bɔli farati dɔgɔya kosɛbɛ.

· Anti-Bleed & Residue-Free Certification : Aw bɛ sɛgɛsɛgɛli rapɔɔriw ɲini minnu ɲɛsinnen bɛ SMT sanu bolokɔniw lakanani ma, ani ka foro sɛgɛsɛgɛli yɛrɛ kɛ ni fɛnw ye.

III. Taabolo wɔɔrɔ-kɔlɔsili sariya

1. Pre-Lamination: Surface Cleaning & Sani ka furakɛli kɛ

· Tumu bɔli dafalen : Sanu bolokɔniw ni PCB lamini yɔrɔw ka kan ka kɛ ni sumaya nɔgɔw ye, tulu nɔgɔlenw ani flux tolenw tɛ u la. Aw bɛ a ko ni fini ye min tɛ wuluwulu kɛ, min sutura etanɔli jilama walima alikɔli isoporopili (IPA) la, o kɔ aw bɛ a ja pewu fiɲɛ na.

· Suba jalen : Aw bɛ a lajɛ ni PCBw tɛ ji bɔ pewu sani u ka kaseti kɛ.

2. Lamination: Zero Tension & Fiɲɛ bɔli dafalen

· Aw kana kaseti lamaga: PTFE substrat bɛ ni ductility ɲuman ye. Ni aw bɛ aw senw kɔrɔta lamini waati la, o bɛ kɔnɔna degun bila a la min bɛ kɛ sababu ye ka a dɔgɔya funteni caman na, o bɛ na ni nɔrɔlenw tigɛcogo ye, tolenw walima joli bɔli jɔyɔrɔ la. Aw bɛ kaseti da a yɛrɛ la sanu bolokɔninw kan ka a digi dɔɔni dɔɔni walasa a ka nɔrɔ a daminɛ na.

· Fiɲɛ bɔli dafalen : Aw bɛ baara kɛ ni wuluwulu walima sɔgɔlan gɛlɛn ye min kɛrɛnkɛrɛnnen don walasa ka a gɛrɛ dɔɔni dɔɔni sira kelen fɛ ka bɔ cɛmancɛ la ka taa a fan fila bɛɛ la walasa ka a sɔgɔsɔgɔ kosɛbɛ. Aw bɛ a lajɛ ni dawolo nɔrɔli dafalen don ni fiɲɛ bugunw sirilen tɛ; bugunw bɛ bonya funteni kɔrɔ ani ka kaseti dawolo kɔrɔta, o bɛ kɛ sababu ye ka nɛgɛw falen.

· Labɛnni tigitigi : Aw bɛ kaseti dawolow labɛn ka kɛɲɛ ni sanu bolokɔniw dawolo ye walima ka u don dɔɔni ni milimɛtɛrɛ 0,2–0,5 ye (ni a dilanni bɛ sira di). Aw kana fɛnɲɛnamafagalanw walima fɛnɲɛnamafagalanw datugu abada, barisa kapilɛri sifoni bɛna nɛgɛfugulan wulilen sama ka taa kɛnɛma.

3. Reflow Soldering: Aw bɛ funteni cogoya ɲɛ

· Aw bɛ kaseti funteni hakɛ fɔlenw labato kosɛbɛ: Aw bɛ pankurun sanfɛla funteni yɛrɛ suman walasa ka a jira ko funteni hakɛ min bɛ se ka caya ani ka a sumaya waati bɛɛ to kaseti ka muɲuli hakɛ kɔnɔ.

· Sumaya sira nɔgɔman : Aw bɛ funteni hakɛ dɔɔni dɔɔni (<2°C/s) mara sani aw ka se nɔrɔli nɔgɔyayɔrɔ la (150°C–200°C). Funteni barikama barikama bɛ nɔrɔ nɔgɔya joona ani ka a sɔgɔli tiɲɛ, o bɛ na ni joli jugumanba ye.

4. Peeling waati: Peeling nɛnɛ bɛ na ni nɔ ɲumanw ye

· Aw bɛ a nɛnɛ pewu fo ka se so funteni ma : Solder kɛlen kɔfɛ, aw bɛ makɔnɔni kɛ fo PCB funteni ka jigin ka tɛmɛ 50°C kan (a ka fisa sigida funteni) sani aw ka kaseti bɔ. Nɛgɛ bɛ to ka nɔgɔya ani ka jɛ kosɛbɛ ni funteni ka bon; ni fanga ye ka a sɔgɔ ni funteni ye nɔgɔya la, o bɛ kɛ sababu ye ka layini fara ɲɔgɔn kan ani ka kola tolenw kɛ.

· Ɲɛgɛnɛsiraw bɔli fɛɛrɛ : Aw bɛ ɲɛgɛnw bɔ dɔɔni dɔɔni ni 180° ye ni fanga kelen ye. Aw kana a sama kosɛbɛ ni aw ye resistance sɔrɔ.

5. Taabolo ɲɛnabɔli: Kɔlɔsili Shelf Life & Reuse Cycles

· Aw bɛ a kɛ ka a kɛ joona : PCB minnu bɛ ni kase lamininen ye, olu ka kan ka don reflow foro la joona. Aw bɛ aw yɛrɛ tanga a marali ma waati jan kɔnɔ (lɛrɛ 24 ni kɔ) atelier kɔnɔ walasa ka ji minta ni buguri dalajɛli bali.

· A bɛ kɛ siɲɛ kelen dɔrɔn foro tɛmɛni kama : SMT kaseti funteni ka bon, o ye fɛn ye min bɛ se ka kɛ siɲɛ kelen. Hali ni kaseti bɛ i n’a fɔ a ma tiɲɛ foro kelen tɛmɛnen kɔfɛ, nɔrɔlan ye ɲɔgɔndan kɛ ani ka kɔrɔbaya; tasuma-fanga-sɛrɛ filanan bɛna kɛ sababu ye ka nɔrɔ tolen walima nɔrɔli dɛsɛ. Ni PCB minnu bɛ sigi fan fila kan, aw bɛ u falen ni kaseti kura ye sani aw ka fan filanan baara tɛmɛ fɔlɔ kɔfɛ.

6. Dɛsɛ Kɔrɔtɔko ɲɛnabɔli & Tiɲɛni

· Koli tolen misɛnninw bɔli : Aw bɛ a dilanni jɔ joona ni tolen sɔrɔla. Aw bɛ a ko dɔɔni dɔɔni ni finimugu ye min sugalen don ni IPA ye; ka pankurunw ci baarakɛlaw ka saniya kama ni bana jugumanw don. Aw kana a sɔgɔ abada ni baarakɛminɛn gɛlɛnw ye.

· Kasɛti kura ka setigiya tiɲɛni : Ka kɔrɔbɔli dafalen kɛ ni PCB 1:1 yɛrɛyɛrɛw ye. Furancɛ tɛmɛnen kɔfɛ, aw bɛ kaseti bɔ ka sanu bolokɔni yɔrɔw lajɛ 40–50x magnifier jukɔrɔ walasa ka zeru tolen ni zeru nɔrɔlenw falenni dafa.
