PTFE High-Temperature Tepi ya FPC Hot Press Lamination Defect Prevention

Monga katswiri wopanga tepi yotentha kwambiri ya PTFE, Jiangsu Aokai New Materials amakupatsirani tsatanetsatane. Mu otentha atolankhani lamination ndondomeko ya Flexible Printed Circuit Boards (FPC), PTFE high-temperature tepi imatchula zolakwika ziwiri zazikulu - makwinya a gawo lapansi ndi zomatira kutengerapo - kupyolera mu zotsatira zophatikizana za katundu wakuthupi (otsika pamwamba pa mphamvu, kukhazikika kwapamwamba) ndi umisiri wokonzedwa bwino wa processing (stacking kapangidwe kamangidwe, kulamulira chizindikiro). Imagwira ntchito ngati wosanjikiza wabwino wodzipatula  komanso wosanjikiza wofanana ndi buffer.

I. Zomwe Zimayambitsa Makwinya a Gawo Lapansi ndi Kusamutsira Zomatira

Makwinya a gawo lapansi Choyambitsa chagona pa kutentha kosafanana ndi kugawa kwamphamvu. FPC imapangidwa ndi zinthu zingapo monga filimu ya PI, zojambula zamkuwa ndi zomatira zokhala ndi ma coefficients osiyanasiyana akukula kwamafuta (CTE). Kuphatikiza apo, mapangidwe a board board kuphatikiza makulidwe amkuwa osagwirizana ndi masitepe olimba amabweretsa kugawa kosagwirizana. Kutentha kopanda yunifolomu ndi kupanikizika kumapangitsa kupsinjika kwa zinthu zamkati, zomwe zimapangitsa makwinya, kupindika ndi kugwa.

Adhesive Transfer (Residual Adhesive) Izi zimachitika makamaka chifukwa cha mawonekedwe ndi zolakwika zakuthupi. The theka-anachiritsa zomatira chivundikiro filimu lamination amasungunuka ndi umayenda pansi kutentha, ndipo amamatira pamwamba pa kudzipatula zipangizo. Panthawiyi, ngati zomatira za silikoni zogwira ntchito kumbuyo kwa tepi ya PTFE zili ndi kutentha kosakwanira kukana kapena kusagwirizana ndi ndondomeko, kulephera kwa mgwirizano kudzachitika pa kutentha kwakukulu, kuchititsa kutengerako zomatira pamwamba pa FPC.

II. Njira Zazikulu za PTFE High Temperature Temper for Defect Prevention

Kupewa Kukwinya kwa gawo lapansi

Kudzipatula kwachiwopsezo cha kutentha & kugawa kwamphamvu kwamtundu umodzi Munjira yokhazikika: mbale yotentha → tepi ya PTFE → khushoni ya silikoni → FPC → PTFE tepi → mbale yotentha , tepi ya PTFE imakhala ngati gawo lotulutsa. Matenthedwe ake okhazikika amatsimikizira kutentha kwamtundu umodzi. Kugwirizana ndi ma cushions a silicone, kumachepetsa kupsinjika komwe kumachitika chifukwa cha kusiyanasiyana kwamafuta ndikuwongolera kupanikizika konse, kupewa kupsinjika komweko komanso makwinya kotsatira. Pofuna kupanga mwatsatanetsatane, tepi ya galasi-fiber yolimbitsa PTFE yokhala ndi CTE yochepa imalimbikitsidwa kuti ikhale yokhazikika.

Zenera lokhazikika lopangira matenthedwe Chosanjikiza cha PTFE chimatchinga kukhudza kwamafuta mwachindunji. Kuphatikizidwa ndi hysteresis yotentha ya ma cushions a silicone, kuwongolera kutentha kumakhala kofatsa komanso kokhazikika. Imawongolera kutentha kwa interlayer mkati mwa ≤ 5 ~ 7 ℃ panthawi yomatira, kupangitsa kuti mpweya utsike musanayambe kuchiritsa zomatira, ndikuchotsa makwinya omwe amayamba chifukwa cha gel osakaniza komanso kuchedwa kwa utsi. Kutentha kwa kutentha kwa gawo lalikulu la kutentha kumalimbikitsidwa kuti 4.5 ~ 5.0 ℃/min.

Kuchotsa Adhesive Transfer

Katundu wosamata wokhala ndi mphamvu zotsika kwambiri PTFE imakhala ndi mphamvu zotsika kwambiri (＜18 mN/m), zotsika kwambiri kuposa utomoni wosungunuka ndi zomatira. Ndi ntchito yabwino kwambiri yopanda ndodo yofanana ndi yophika yopanda ndodo, imatha kusenda mosavuta mukatha kuyanika popanda kukanda magawo a FPC kapena kusiya guluu wotsalira.

Kusankhidwa kwa makina opangira makina apamwamba kwambiri Kuti mupewe kusuntha kwa tepiyo, tepi ya PTFE yopangidwa ndi zomatira zamtundu wapamwamba za silikoni zidzatengedwa. Zomatira za silicone zoyambira zimasunga magwiridwe antchito mpaka 260 ℃, kuonetsetsa kuti guluu wotsalira ziro pakupanga kwanthawi yayitali. Kutentha kukana kalasi kudzakwaniritsa zofunikira za ndondomeko (210-260 ℃).

Kuchiza Kokwanira Zomatira Pa ❖ kuyanika ndi kupanga tepi ya Aokai PTFE, nthawi yochiritsira yosayenera, kutentha kapena kuthamanga kumayambitsa kuchiritsa kwa zomatira kosakwanira, zomwe zimayambitsa zovuta zotsalira zomatira pazotsatira.

Zomwe zili pamwambapa zimaperekedwa ndi Jiangsu Aokai New Material Technology Co., Ltd.

Ngati mukufuna zambiri zokhudzana ndi zomwe zimapangidwira, mawonekedwe ogwiritsira ntchito ndi mayankho makonda amtundu wathu wonse, kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi ya PTFE yotentha kwambiri, lamba wotentha kwambiri wa PTFE, lamba wamakina osatsekeka, lamba wamtundu umodzi wa PTFE, nsalu yotchinga yamtundu umodzi, lamba wotentha kwambiri wosamva kutentha kwagalasi, chonde lamba wosamva kutentha kwagalasi:

Nthawi zonse timatsatira malingaliro abizinesi a ukatswiri ndi umphumphu, ndikupereka mayankho amtundu umodzi wamakampani ndi ntchito zosinthidwa mwamakonda kwa makasitomala apadziko lonse lapansi.
