PTFE High-ubushushu Tape for FPC Hot Press Lamination yokuLamination Prevention

Njengomvelisi oqeqeshiweyo we-PTFE tape yobushushu obuphezulu, i-Jiangsu Aokai New Materials ikunika ingcaciso eneenkcukacha. Kwinkqubo yokucoca i-hot press lamination ye-Flexible Printed Circuit Boards (FPC), i-PTFE high-temperature tape idilesi iziphene ezibini eziphambili - i-substrate wrinkling kunye nokudluliselwa kwe-adhesive - ngokusebenzisa imiphumo edibeneyo yezinto eziphathekayo eziphathekayo (amandla aphantsi komhlaba, ukuzinza okuphezulu komgangatho) kunye nobuchwepheshe bokucubungula (i-stacking structure, control parameter). Isebenza njengomaleko ococekileyo ococekileyo  kunye noxinzelelo olulinganayo lwebuffer.

I. Iimbangela ze-Substrate Wrinkling kunye ne-Adhesive Transfer

Ukushwabana kweSubstrate Oyena nobangela ulele kubushushu obungalinganiyo kunye nokusabalalisa uxinzelelo. I-FPC yenziwe ngezinto ezininzi ezifana nefilimu ye-PI, i-copper foil kunye ne-adhesives ene-coefficients eyahlukeneyo yokwandiswa kwe-thermal (CTE). Ukongeza, izinto zokuyila ibhodi yesekethe kubandakanya ubukhulu bobhedu obungalinganiyo kunye namanyathelo okuqina kuya kukhokelela kuxinzelelo olungalinganiyo. Ubushushu obungafaniyo kunye noxinzelelo lubangela uxinzelelo lwangaphakathi lwempahla, olukhokelela ekushwabaneni, ukulwa kunye ne-delamination.

I-Adhesive Transfer (I-Residual Adhesive) Oku kubangelwa ikakhulu yi-interface kunye neziphene zezinto. I-adhesive semi-cured adhesive of cover film for lamination iyanyibilika kwaye ihamba phantsi kobushushu obuphezulu, kwaye ibambelele kumphezulu wezinto zokuzihlukanisa. Okwangoku, ukuba i-silicone ye-adhesive-sensitive i-adhesive i-adhesive ngasemva ye-PTFE tape ayinayo ukumelana nobushushu okanye imilinganiselo yenkqubo engafanelekanga, ukungaphumeleli kokubambisana kuya kwenzeka kwiqondo lokushisa eliphezulu, okubangela ukudluliselwa kwe-adhesive inxalenye kwi-FPC surface.

II. IiNdlela ezingundoqo ze-PTFE iTeyiphu yoBubushushu obuPhezulu boThintelo lwesiphene

Ukuthintelwa kweSubstrate Wrinking

Ukwahlula ukothuka kweThermal & nonikezelo loxinzelelo olufanayo Kumgangatho wokupakishwa okusemgangathweni: Ipleyiti eshushu → PTFE tape → umqamelo wesilicone → FPC → PTFE tape → ipleyiti eshushu , iteyiphu yePTFE isebenza njengomaleko wokukhulula. I-conductivity yayo ezinzileyo ye-thermal iqinisekisa ukuhanjiswa kobushushu obufanayo. Ukusebenzisana ne-silicone buffer cushions, ikhulula uxinzelelo olubangelwa kukwandiswa kwe-thermal eyahlukileyo kunye nokulinganisa uxinzelelo olupheleleyo, ukuphepha ukuxininisa koxinzelelo lwendawo kunye nokushwabana okulandelayo. Kwimveliso ephezulu echanekileyo, i-glass-fiber eqiniswe kwi-PTFE tape kunye ne-CTE ephantsi iyacetyiswa ukuba i-dimensional stability ephezulu.

Iwindow ezinzileyo yokusetyenzwa kwe-thermal I-PTFE iibhloko zeebhloko ezithe ngqo zobushushu. Ukudibanisa ne-thermal hysteresis ye-silicone cushions, ukuqhutyelwa kokushisa kuba mnene kwaye kuzinzile. Ilawula umahluko weqondo lobushushu phakathi kwe-≤ 5 ~ 7 ℃ ngexesha lokuncamathelisa i-gelling, ivumela ukukhupha komoya okupheleleyo ngaphambi kokunyangeka kokuncamathelisa, kwaye ngokusisiseko isusa imibimbi ebangelwa kukugelling kwangaphambi kwexesha kunye nokulibaziseka kokuphuma. Izinga lokufudumala kwecandelo eliphambili lokunyuka kweqondo lokushisa linconywa ukuba lilawulwe kwi-4.5 ~ 5.0 ℃ / min.

Ukupheliswa kokuTshintshela okuncamathelayo

Ipropathi engancamatheliyo ene-ultra-low surface energy I-PTFE ibonakalisa amandla aphantsi kakhulu kumphezulu (＜18 mN/m), isezantsi kakhulu kunentlaka etyhidiweyo kunye nezinto ezincamathelayo. Ngomsebenzi ogqwesileyo wokungakhuni okufana ne-cookware engagxiliyo, inokuxotyulwa ngokulula emva kokuba i-lamination ngaphandle kokukrwela ii-substrates ze-FPC okanye ukushiya i-glue eshiyekileyo.

Ukukhethwa kwenkqubo yokunamathela okuphezulu Ukuphepha ukuhanjiswa kwe-self-adhesive ye-tape, i-PTFE tape eyenziwe nge-adhesive ephezulu ye-silicone yoxinzelelo-sensitive iyakwamkelwa. I-adhesive ye-silicone ye-Premium igcina ukusebenza okuzinzileyo ukuya kuthi ga kwi-260 ℃, iqinisekisa i-zero residual glue kwimveliso eqhubekayo yexesha elide. Umgangatho wokumelana nobushushu uya kuhlangabezana ngokupheleleyo neemfuno zenkqubo (210–260 ℃).

Ukunyangwa okupheleleyo kwe-Adhesives Ngexesha lokugquma kunye nokuveliswa kwe-tape ye-Aokai PTFE, ixesha elingafanelekanga lokunyanga, ubushushu okanye isantya sokubaleka kuya kukhokelela ekunyangeni okungaphelelanga kokuncamathelisa, okubangela ngakumbi iingxaki zokuncamathela ezishiyekileyo kwisicelo esilandelayo.
