Mawu Oyamba
A flex PCB ndi mtundu wapadera wa PCB womwe mutha kupindika kukhala mawonekedwe omwe mukufuna.Amagwiritsidwa ntchito kwambiri popanga kachulukidwe komanso kutentha kwambiri.
Chifukwa cha kukana kwambiri kutentha, mapangidwe osinthika ndi abwino kwa zigawo zopangira solder.Filimu yowonekera ya polyester yomwe imagwiritsidwa ntchito popanga mapangidwe osinthika imakhala ngati gawo lapansi.
Mutha kusintha makulidwe amkuwa kuchokera ku 0.0001 ″ mpaka 0.010 ″, pomwe zida za dielectric zitha kukhala pakati pa 0.0005 ″ ndi 0.010 ″ wandiweyani.Zolumikizana zochepa pamapangidwe osinthika.
Choncho, pali zochepa soldered malumikizidwe.Kuphatikiza apo, mabwalowa amatenga 10% yokha ya malo olimba a board
chifukwa cha kusinthika kwawo kusinthika.
Zakuthupi
Zipangizo zosinthika komanso zosunthika zimagwiritsidwa ntchito popanga ma PCB osinthika.Kusinthasintha kwake kumapangitsa kuti itembenuke kapena kusuntha popanda kuwonongeka kosasinthika kwa zigawo zake kapena zolumikizira.
Chigawo chilichonse cha flex PCB chiyenera kugwira ntchito limodzi kuti chigwire ntchito.Mudzafunika zida zosiyanasiyana kuti mupange bolodi yosinthika.
Kuphimba Layer Substrate
Conductor chonyamulira ndi insulating sing'anga amazindikira ntchito ya gawo lapansi ndi filimu.Kuphatikiza apo, gawo lapansi liyenera kupindika ndi kupindika.
Mapepala a polyimide ndi poliyesitala amagwiritsidwa ntchito kwambiri m'mabwalo osinthika.Awa ndi ochepa chabe mwa mafilimu ambiri a polima omwe mungapeze, koma pali ena ambiri omwe mungasankhe.
Ndi chisankho chabwinoko chifukwa chotsika mtengo komanso gawo lapansi lapamwamba.
PI polyimide ndizomwe zimagwiritsidwa ntchito kwambiri ndi opanga.Mtundu uwu wa utomoni wa thermostatic umatha kupirira kutentha kwambiri.Choncho kusungunuka si vuto.Pambuyo polima polima, imasungabe kusinthasintha kwake komanso kusinthasintha.Kuphatikiza pa izi, ili ndi zinthu zabwino kwambiri zamagetsi.
Zida Zoyendetsa
Muyenera kusankha chinthu cha conductor chomwe chimasamutsa mphamvu bwino kwambiri.Pafupifupi mabwalo onse osaphulika amagwiritsa ntchito mkuwa ngati kondakitala woyamba.
Kuwonjezera pa kukhala kondakitala wabwino kwambiri, mkuwa ndi wosavuta kuupeza.Poyerekeza ndi mtengo wa zida zina zopangira, mkuwa ndi malonda.Conductivity sikokwanira kutaya kutentha bwino;iyeneranso kukhala kondakitala wabwino wamafuta.Mabwalo osinthika amatha kupangidwa pogwiritsa ntchito zida zomwe zimachepetsa kutentha komwe zimapanga.
Zomatira
Pali zomatira pakati pa pepala la polyimide ndi mkuwa pa bolodi iliyonse yosinthika.Epoxy ndi acrylic ndi zomatira ziwiri zazikulu zomwe mungagwiritse ntchito.
Zomatira zamphamvu zimafunikira kuti zitheke kutentha kwambiri kopangidwa ndi mkuwa.
