Tsatanetsatane wa Zamalonda

Mfundo Zachidwi Pamapangidwe a Rigid Flexible Combination Zone

1.Mzere uyenera kusintha bwino, ndipo mayendedwe a mzerewo ayenera kukhala perpendicular kwa njira yopindika.

2.Kondakitala azigawidwa mofanana m'dera lonse lopindika.

3.Kutalikira kwa kokondakita kudzakulitsidwa kudera lonse lopindika.

Mapangidwe a 4.PTH sayenera kugwiritsidwa ntchito m'malo osinthika osinthika.

5.Kupindika kozungulira kwa zone yopindika ya PCB yokhazikika

Zida Za Flexible PCB

Aliyense amadziwa zinthu zolimba, ndipo mitundu ya FR4 imagwiritsidwa ntchito nthawi zambiri.Komabe, zofunika zambiri ayenera kuganiziridwa kwa okhwima kusintha zipangizo PCB.Ayenera kukhala oyenera adhesion, wabwino kutentha kukana, pofuna kuonetsetsa kuti okhwima flexural chomangira gawo limodzi la kukula pambuyo Kutentha popanda mapindikidwe.opanga General ntchito utomoni mndandanda wa okhwima PCB zipangizo.

Pazinthu zosinthika, sankhani gawo lapansi ndikuphimba filimu yokhala ndi kukula kwakung'ono ndi kupindika.Nthawi zambiri gwiritsani ntchito zida zolimba za PI, komanso kugwiritsa ntchito mwachindunji gawo lapansi lopanda zomatira popanga.Zida za flex ndi izi:

Zida Zoyambira: FCCL (Flexible Copper Clad Laminate)

PI.Polymide: Kapton (12.5 um / 20 um / 25 um / 50 um / 75um).Kusinthasintha kwabwino, kukana kutentha kwanthawi yayitali (kutentha kwanthawi yayitali ndi 260 ° C, kwakanthawi kochepa 400 ° C), kuyamwa kwa chinyezi chambiri, mawonekedwe abwino amagetsi ndi makina, kukana misozi yabwino.Kukana kwa nyengo yabwino, kukana kwa mankhwala ndi kuchedwa kwamoto.Polyester imide (PI) ndi yomwe imagwiritsidwa ntchito kwambiri.PET.Polyester (25 um / 50 um / 75um).Zotsika mtengo, zabwino kusinthasintha ndi kukana misozi.Zabwino zamakina ndi zamagetsi monga kulimba kwamphamvu, kukana madzi abwino komanso hygroscopicity.Koma pambuyo potenthedwa, kuchuluka kwa kuchepa kumakhala kwakukulu ndipo kutentha kwapamwamba kumakhala kosauka.Sayenera kutenthedwa kutentha kwambiri, malo osungunuka 250 ° C, osagwiritsidwa ntchito pang'ono

Kuphimba Membrane

Ntchito yaikulu ya filimu yophimba ndikuteteza dera, kuteteza dera ku chinyezi, kuipitsidwa ndi kuwotcherera.The Conductive Layer ikhoza kukulungidwa Annealed Copper, Electrodeposited Copper ndi Silver Ink.Kapangidwe ka kristalo ka mkuwa wa electrolytic ndi wovuta, womwe siwothandiza kuti pakhale zokolola zabwino.Kalendala mkuwa kristalo dongosolo ndi yosalala, koma adhesion ndi maziko filimu ndi osauka.Angasiyanitsidwe ndi maonekedwe a banga ndi kugubuduza mkuwa zojambulazo.Chojambula chamkuwa cha Electrolytic ndi chofiira chamkuwa, zojambulazo za calendering zamkuwa zimakhala zotuwa zotuwa.Zida Zowonjezera &Stiffeners: Zomwe zimapanikizidwa mu gawo la flex PCB pazinthu zowotcherera kapena kuwonjezera zowuma pakuyika.Filimu yolimbikitsa yomwe ikupezeka FR4, mbale ya utomoni, zomatira zovutirapo, zomatira zomatira, chitsulo chowonjezera chachitsulo cha aluminiyamu, etc.

Mapepala osatuluka/Otsika Otsika guluu semi-ochiritsidwa (Low Flow PP).Maulumikizidwe okhwima ndi Flex amagwiritsidwa ntchito pa Rigid flex PCB, nthawi zambiri PP woonda kwambiri.
