Flexible printed circuit boards yog ib hom khoom siv hluav taws xob uas tsim los rau ntau yam. Nws cov txiaj ntsig ntawm cov rooj sib tham ib txwm muaj xws li txo qis kev sib dhos ua haujlwm, ua kom muaj zog dua nyob rau hauv ib puag ncig hnyav, thiab muaj peev xwm tuav cov khoom siv hluav taws xob ntau dua. Cov kab hluav taws xob hluav taws xob no yog tsim los siv cov ntawv ci tooj liab electrolytic, cov khoom siv tau sai sai ua pov thawj tias yog ib qho tseem ceeb tshaj plaws hauv kev lag luam hluav taws xob thiab kev sib txuas lus.

Yuav Ua Li Cas Flex Circuits Ua

Flex Circuits yog siv nyob rau hauv electronics rau ntau yam laj thawj. Raws li tau hais ua ntej, nws txo qis kev sib dhos yuam kev, yog ib puag ncig-resilient, thiab tuaj yeem tswj cov khoom siv hluav taws xob nyuaj. Txawm li cas los xij, nws tseem tuaj yeem txo cov nqi zog, txo qhov hnyav thiab qhov xav tau ntawm qhov chaw, thiab txo cov ntsiab lus sib txuas uas ua rau muaj kev ruaj ntseg. Rau tag nrho cov laj thawj no, flex circuits yog ib qho ntawm cov khoom siv hluav taws xob ntau tshaj plaws hauv kev lag luam.

A hloov tau luam tawm Circuit CourtNws yog tsim los ntawm peb lub ntsiab tseem ceeb: Tus neeg xyuas pib, Adhesives, thiab Insulators. Nyob ntawm cov qauv ntawm cov flex circuits, peb cov ntaub ntawv no yog npaj rau tam sim no kom ntws mus rau hauv cov neeg siv khoom xav tau, thiab rau nws cuam tshuam nrog lwm yam khoom siv hluav taws xob. Cov khoom siv ntau tshaj plaws rau flex Circuit Court cov nplaum yog epoxy, acrylic, PSAs, lossis qee zaum tsis muaj, thaum siv cov insulators feem ntau suav nrog polyester thiab polyamide. Txog tam sim no, peb txaus siab tshaj plaws rau cov conductors siv hauv cov circuits no.

Thaum lwm yam khoom siv xws li nyiaj, carbon, thiab txhuas tuaj yeem siv tau, cov khoom siv feem ntau siv rau cov neeg siv khoom yog tooj liab. Copper foil yog suav tias yog cov khoom tseem ceeb rau kev tsim cov flex circuits, thiab nws yog tsim nyob rau hauv ob txoj kev: dov annealing los yog electrolysis.

Copper Foils Ua li cas

Rolled annealed tooj liab ntawv ciyog tsim los ntawm dov rhuab los ntawm tooj liab, thinning lawv thiab tsim ib tug du tooj liab nto. Cov nplooj ntawv tooj liab raug rau qhov kub thiab txias los ntawm txoj kev no, ua kom lub ntsej muag du thiab txhim kho ductility, khoov, thiab conductivity.

Lub caij no,electrolytic tooj liab foil yog tsim los ntawm kev siv cov txheej txheem electrolysis. Cov tshuaj tooj liab yog tsim nrog sulfuric acid (nrog rau lwm yam additives nyob ntawm qhov chaw tsim tshuaj paus specifications). Ib qho electrolytic cell yog khiav los ntawm cov tshuaj, uas tom qab ntawd ua rau tooj liab ions los nag thiab av ntawm lub cathode nto. Cov tshuaj ntxiv kuj tseem tuaj yeem ntxiv rau cov tshuaj uas tuaj yeem hloov kho nws cov khoom sab hauv nrog rau nws cov tsos.

Cov txheej txheem electroplating no txuas ntxiv mus txog thaum lub nruas cathode raug tshem tawm ntawm cov tshuaj. Lub nruas kuj tseem tswj tau qhov tuab ntawm cov ntawv ci tooj liab yuav ua li cas, vim tias lub nruas nrawm dua kuj tseem nyiam cov dej nag ntau dua, ua kom cov ntawv ci tuab.

Txawm li cas los xij, tag nrho cov ntaub ntawv tooj liab uas tsim los ntawm ob txoj hauv kev no tseem yuav raug kho nrog kev sib txuas, kev kho cua sov, thiab kev ruaj ntseg (anti-oxidation) tom qab. Cov kev kho mob no ua rau cov ntawv ci tooj liab tuaj yeem khi zoo dua rau cov nplaum, ua kom muaj zog ntau dua rau cov cua sov koom nrog hauv kev tsim cov ntawv luam tawm tiag tiag, thiab tiv thaiv oxidation ntawm cov ntawv ci tooj liab.

Rolled Annealed vs Electrolytic

Vim tias cov txheej txheem tsim cov ntawv ci tooj liab ntawm dov annealed thiab electrolytic tooj liab ntawv ci txawv, lawv kuj muaj qhov sib txawv thiab qhov tsis zoo.

Qhov sib txawv tseem ceeb ntawm ob daim ntawv tooj liab yog nyob rau hauv cov nqe lus ntawm lawv cov qauv. Rolled annealed tooj liab ntawv ci yuav muaj kab rov tav qauv ntawm qhov kub thiab txias, uas tom qab ntawd morphs rau hauv cov qauv lamellar siv lead ua thaum raug kub siab thiab kub. Lub caij no, electrolytic copper foil khaws nws cov qauv columnar ntawm ob qho tib si kub thiab kub siab thiab kub.

Qhov no tsim qhov sib txawv ntawm cov conductivity, ductility, bendability, thiab tus nqi ntawm ob hom ntawv ci tooj liab. Vim hais tias dov annealed tooj liab foils feem ntau smoother, lawv yog cov conductive ntau dua thiab tsim nyog rau cov xov hlau me me. Lawv kuj tseem muaj ntau dua thiab feem ntau yog khoov dua li electrolytic tooj liab ntawv ci.

Txawm li cas los xij, qhov yooj yim ntawm txoj kev electrolysis kom ntseeg tau tias electrolytic copper foil muaj tus nqi qis dua li dov annealed tooj liab foils. Txawm li cas los xij, nco ntsoov tias lawv yuav yog qhov kev xaiv zoo tshaj plaws rau cov kab me me, thiab tias lawv muaj qhov cuam tshuam tsis zoo dua li dov annealed tooj liab foils.

Hauv kev xaus, electrolytic copper foils yog ib qho kev xaiv zoo uas tsis muaj nqi raws li cov neeg siv khoom hauv cov ntawv luam tawm yooj yim. Vim hais tias ntawm flex Circuit Court qhov tseem ceeb hauv electronics thiab lwm yam lag luam, nws, nyob rau hauv lem, ua electrolytic tooj liab foils ib yam khoom tseem ceeb thiab.
