Aw fɔ Prɛvent Adhesive Residue & Adhesive Bleed fɔ PTFE High-Temperature Tape We yu de Protɛkt PCB Gold Finga dɛn na SMT Maunting

Jiangsu Aokai Nyu Matirial, we na wan pɔshɔnal manifakta fɔ PTFE ay-tɛmpracha tep, de gi pɔshɔnal gayd. We dɛn yuz PTFE ay-tɛmpracha tep fɔ protɛkt PCB gold finga dɛn we dɛn de gɛda SMT, di adeziv rɛsɛdyu (stika dipɔsit dɛn we dɛn lɛf pan gold finga dɛn afta dɛn dɔn pul di tep) ɛn adhesive blɔd (adhesive de sof ɛn ɔvaflɔ ɔnda ay tɛmpracha, kɔntaminant eria dɛn we nɔ protɛkt ɔ PCB sɔfays) afta riflɔ sɔlda na di men tin we kin apin bikɔs dɛn nɔ pik di tep di rayt we ɔ we dɛn nɔ mach prɔses paramita dɛn. Dis dɔŋ ya na wan sistamat sɛt fɔ sɔlvishɔn dɛn:

I. Rut Kɔz Analysis ɔf Adhesive Rɛsidyu & Blid

1. Adhesive Residue  I kin apin we di adhesive de sofa kohesive failure (internal tearing of the adhesive layer) ɔ intafacial transfer failure (adhesive detach frɔm di substrate ɛn stik to gold finga dɛn). Di kɔmɔn tin dɛn we kin mek pɔsin nɔ ebul fɔ du sɔntin na we di tep nɔ de mek di tɛmpracha nɔ ebul fɔ du am, di adhesive we dɔn ol, ɔ di tɛm we i nɔ de pul di wata fayn fayn wan.

2. Adhesive Bleed  Di viskositi fɔ di adhesive de drɔp shap wan ɔnda riflɔ ay tɛmpracha, we de mek di fluiditi inkrisayz bad bad wan. כnda lamination prεshכn εn kapilari akshכn, di adhesive de כvaflow di tep ed. Dis kin apin bay we di adhesive coating we tik pasmak, we di tɛmpracha de go ɔp kwik kwik wan, ɔ we di adhesive insɛf nɔ de mek di tɛmral krip nɔ fayn.

II. Prɔpa Tep Sɛlɛkshɔn – Di Kɔr Sɔlwɛshɔn

Ɔdinari PTFE tep nɔ kin ebul fɔ mit di ekstrim rikwaymɛnt dɛn fɔ SMT prɔses. Prodakt dɛn we dɛn mek spɛshal fɔ SMT gold finga protɛkshɔn fɔ pik, wit prayoritɛd we dɛn gi fɔ adhesive sistem pefɔmɛns:

 

· Tεmprachכ Rεsistεns Gred : Sכt tεm pik tεmprachכ rεsistεns ≥ 300°C, kכntinyu savis tεmprachכ ≥ 260°C, fa pas di pik tεmprachכ fכ lid-fri rifכ sכlda (245–250°C).

· Adhesive Layer Thickness : Tik we hכy nכ de ikwal to strכng adheshon. Prεfεr tep dεm wit tכtal tiknes 0.08–0.13mm, we gεt tin yet hεy-kכhεshכn adhesive layεr dεm fכ ridyus blכd risk drastikli.

· Anti-Bleed & Residue-Free Certification : Rikwest anti-bleed ɛn residue-fri tɛst ripɔt dɛn we dɛn dediket to SMT gold finga protɛkshɔn frɔm di saplay dɛn, ɛn du aktual ɔfna tɛst wit sɛmpul dɛn.

III. Siks-Step Prɔses Kɔntrol Stɛndad

1. Pri-Lamination: Surface Klin & Pri-Tritmɛnt

· Komplit digris: di gold finga dεm εn di PCB sεf dεm we de rawnd am fכ fri fכ swet stεn, כyl kכntaminεnt εn fluks rεsidεns. Waip wit klos we nɔ gɛt lint we dɛn dɔn dip insay anhaydrous ɛtɛnol ɔ isopropyl alkol (IPA), dɔn ful-ɔp wit ɛya-dray.

· Dray sabstret: Mek shɔ se PCB dɛn nɔ gɛt mɔstɔ kɔmplit wan bifo dɛn put di tep.

2. Lamination: Ziro Tɛnshɔn & Ful Ɛya Ɛvakueshɔn

· Nɔ strɛch di tep: PTFE sabstret gɛt gud daktiliti. we yu strεch di tεm we dεn de laminεshכn de mek intanεt strεs we de trigεr shrinkage כnda hכy tεmprachכ, we de rεsult in adhesive tearing, rεsidyu כ posishכnal blכd. Le di tep flat naturally ova gold finga dɛn ɛn pres layt wan fɔ initial adhesion.

· Ful ay rimobul: Yuz wan dediket rɔla ɔ had skrapa fɔ push sloslo wan dairekshɔn frɔm sɛnt to ɔl tu di sayd fɔ ful kɔmpakshɔn. Mek shɔ se di ed adheshon kɔmplit witout trap air bubbles; di bכbul dεm de εkspכnd כnda di כt εn lif di tep ed dεm, we de mek di adhesive כva fכlכ.

· Prɛsis alaynɛshɔn: Align tep edj dɛn flush wit gold finga edj ɔ smɔl inset bay 0.2–0.5mm (if dizayn alaw). Nɔ ɛva kɔba pad ɔ via, bikɔs kapilari sayfon go drɔ mɔlt adhesive go na do.

3. Riflɔ Sɔlda: Optimayz Tɛmpratura Profayl

· Kɔmplit strikt wan wit di tep tɛmpracha spɛsifikɛshɔn dɛn: Mɛzhɔ di aktual bɔd sɔfayz tɛmpracha fɔ garanti pik tɛmpracha ɛn totɛl ɔt durayshɔn de insay di tep in tolɛreshɔn rɛnj.

· Jεntεl hεtin ramp: Mentεn wan slo hεt rεt (<2°C/s) bifo yu rich di adhesive sכftin zon (150°C–200°C). Shap shap tɛmpracha spayk dɛn kin mek di adeziv sof kwik kwik wan ɛn i kin kol in viskɔsiti, ɛn dis kin mek di blɔd kɔmɔt bad bad wan.

4. Peeling Timing: Kol Peeling Deliver Optimal Rizult

· Kul ful wan to rum tɛmpracha: Afta yu dɔn sɔlda, wet te PCB tɛmpracha drɔp dɔŋ 50°C (i fayn fɔ ambiɛnt tɛmpracha) bifo yu pul di tep. Adhesive de stil saf ɛn low-cohesion na ay tempɔret; fכs hot peeling izi wan de mek layt separeshכn εn rεsidyual glu.

· Tεknik fכ pul: Pil sloslo na lכw 180° angle wit yunifכm fכs. Nɔ pul tranga wan if yu mit di resistans.

5. Prɔses Manejmɛnt: Kɔntrol Shelf Layf & Riyuz Saykl dɛn

· Aplay ɛn prosɛs wantɛm wantɛm: PCB dɛn we gɛt laminated tep fɔ go insay di riflɔ ɔfna kwik kwik wan. Nɔ kip am fɔ lɔng tɛm (ɔva 24 awa) na di wokshɔp fɔ mek di wata nɔ go insay di wata ɛn fɔ mek di dɔst nɔ gɛda.

· Singl-yuz ɔl fɔ ɔfna pas: SMT ay-tɛmpracha tep na dispɔzabl kɔnsumabl. Ivin if di tep tan lɛk se i nɔ pwɛl afta wan ɔfna pas, di adeziv dɔn krɔs ɛn ol; wan sεkכn hεt saykl go definitli mek adhesive rεsidεns כ adhesion fεil. Fɔ PCB dɛn we dɛn dɔn mont tu sayd, riples wit brand-nyu tep bifo yu prosɛs di sɛkɔn sayd afta di fɔs pas.

6. Failure Imejɛnsi Handlin & Valideshɔn

· Smɔl rɛsɛdyuɛl glu dispɔzishɔn: stɔp di prodakshɔn wantɛm wantɛm wans dɛn dɔn no di rɛsɛdyu. Waip am jisnɔ wit klos we nɔ gɛt lint we dɛn dɔn dampen pan IPA; sɛn bod fɔ pɔshɔnal klin insay siriɔs kes. Nɔ ɛva skrap wit had tul dɛn.

· Nyu tep kwalifayeshɔn validɛshɔn: Kɔndɔkt ful trayal prodakshɔn wit 1:1 aktual PCB dɛn. Afta di ɔfna pas, pul di tep ɛn inspɛkt di gold finga eria dɛn ɔnda 40–50x magnifya fɔ kɔnfɔm ziro rɛsɛdyu ɛn ziro adhesive ɔvaflɔ.
