Flex Circuit, 1Layer Flexible Print Circuit Board | Mtengo wa YMSPCB

Kodi FPC ndi chiyani?

Flexible Printed Circuits (FPCs), yomwe imatchedwanso Flexible Circuits, kapena Flex Circuits, mwa kutanthauzira kwa IPC, dera losindikizidwa losinthika ndi dongosolo lopangidwa ndi zigawo zosindikizidwa zomwe zimagwiritsa ntchito zinthu zosinthika zokhala ndi chivundikiro chosinthika kapena chopanda chivundikiro. Kutanthauzira uku ndikolondola, ndipo kumapereka zina mwazothekera kutengera kusiyanasiyana komwe kulipo pazida zoyambira, zida zowongolera, ndi zida zotchingira zoteteza. Koma nthawi zina, mabwalo osinthika amatchedwanso Flexible PCB kapena Flex PCB, ndichifukwa choti lingaliro lachilengedwe la anthu ambiri ndikuti dera losinthika ndi bolodi losindikizidwa losindikizidwa (PCB) lopangidwa ndi filimu yosinthika yokhala ndi ma conductor amkuwa pamenepo. Zowonadi, gawo losindikizidwa losinthika limapangidwa ndi zitsulo zazitsulo, nthawi zambiri zamkuwa (kawirikawiri kokhazikika), zomangika ku dielectric wosanjikiza, nthawi zambiri polyimide (kawirikawiri poliyesitala). Inde, multilayer flex circuit ikhoza kukhala ndi zigawo zambiri zazitsulo. Monga wopanga dera losinthasintha, YMSPCB imatha kupanga 8-wosanjikiza flex PCB. Makulidwe a conductive wosanjikiza akhoza kukhala woonda kwambiri (0.47mil, 12μ, 1/3oz) kuti wandiweyani kwambiri (2.8mil, 70μ, 2oz) ndi makulidwe a dielectric amatha kusiyana ndi 0.5mil (13μ) mpaka 5mil (125μ). Flexible copper clad laminates (FCCL) akhoza kukhala mbali imodzi ndi mbali ziwiri kapena popanda wosanjikiza wa zomatira kuti amangirire chitsulo ku gawo lapansi. Flexible circuits (FPC) amagwiritsidwa ntchito pazinthu zambiri, kuyambira pazogulitsa zotsika kwambiri mpaka zida zapamwamba kwambiri zankhondo ndi zamalonda. Sizodabwitsa kuti mitundu yazinthu zomwe zimagwiritsidwa ntchito popanga mabwalowa ndizosiyana kwambiri ndi momwe zimagwirira ntchito. Ma PCB osinthika amagwiritsidwa ntchito kwambiri pazida zamagetsi monga gawo lofunikira lomwe limapereka maubwino okhala ocheperako, ochepa thupi, komanso osinthika kwambiri. Monga opanga odalirika osinthika, timathandizira mitundu yonse ya 1-8 zigawo zosinthika mabwalo, kuphatikiza mabwalo osunthika okhala ndi ma thru-hole cholumikizira, okwiriridwa ndi / kapena akhungu kudzera pakulumikizana, kukwiriridwa ndi kulumikizidwa kwakhungu kwa microvia. Komanso, YMSPCB imathandizira inki ya kaboni, inki ya siliva, yokhazikika, ndi ma hatch impedance amawongolera mabwalo osinthika.

Zojambula Zosiyanasiyana Zamkuwa Zogwiritsidwa Ntchito mu Flex Circuit

Chojambula chamkuwa chomwe chimagwiritsidwa ntchito mu FPC chimadalira ntchito.

[Njira Yonse]

Chojambula chamkuwa chomwe chimagwiritsidwa ntchito mu PCB wamba chimakhala ndi mitundu iwiri, zojambulazo za electrodeposited zamkuwa ndi zojambulazo zamkuwa, ndipo zimagwiritsidwa ntchito muzojambula zosiyanasiyana.

Electrodeposited copper zojambulazo zimagwiritsidwa ntchito muzopanda zosinthika zosinthika Zopangidwa ndi zida zopukutira zamkuwa zitha kuyambitsa kupsinjika kwambiri kenako zimafunika annealing.After annealing, zojambulajambula zamkuwa zopindika zimakhala ndi dongosolo lambewu loyenera kuteteza kufalikira kwa ming'alu.Ndicho chifukwa chake imakhala ndi kukana kwa flexure.
