Intshayelelo yemveliso

Ibhodi yesekethe eguquguqukayo (FPC), eyaziwa ngokuba yibhodi yesekethe eguquguqukayo, ibhodi yesekethe eguquguqukayo, ubunzima bayo obukhanyayo, ubukhulu obuncinci, ukugoba simahla kunye nokugoba kunye nezinye iimpawu ezibalaseleyo. Nangona kunjalo, ukuhlolwa komgangatho wasekhaya we-FPC ikakhulu kuxhomekeke kuhlolo olubonakalayo olwenziwa ngesandla, oluzindleko eziphezulu kunye nokusebenza okuphantsi. Ngophuhliso olukhawulezayo loshishino lwe-elektroniki, uyilo lwebhodi yesekethe luya lusiba ngakumbi kwaye luchanekile oluphezulu kunye noxinaniso oluphezulu, kwaye indlela yokubona incwadi yemveli ayinakukwazi ukuhlangabezana neemfuno zemveliso, kunye nobhaqo oluzenzekelayo lweziphene ze-FPC ibe yinto engenakuphepheka. indlela yophuhliso lwamashishini.

I-Flexible circuit (FPC) bubuchwephesha obuphuhliswe yi-United States kuphuhliso lobuchwepheshe be-rocket yasemkhathini ngeminyaka yoo-1970. Yisekethe eprintiweyo enokuthembeka okuphezulu kunye nokuguquguquka okugqwesileyo okwenziwe ngefilimu yepolyester okanye i-polyimide njenge-substrate. Ngokufakela idizayini yesiphaluka kwiphepha leplastiki elithambileyo eliguquguqukayo, inani elikhulu lamacandelo achanekileyo afakwe kwindawo encinci kunye nencinci. Ngaloo ndlela ukwenza isekethe eguquguqukayo eguquguqukayo. Le sekethi inokugotywa kwaye isongwe ngokuthanda, ubunzima obulula, ubungakanani obuncinci, ukutshatyalaliswa kobushushu obuhle, ukufakwa lula, ukuphula iteknoloji yonxibelelwano lwendabuko. Kwisakhiwo sesekethe eguquguqukayo, izinto eziqulunqwe yifilimu ye-insulating, i-conductor kunye ne-agent agent.

Izinto zecandelo 1, ifilimu yokugquma

Ifilimu ye-insulating yenza isiseko sesiseko sesekethe, kwaye i-adhesive bonds i-foil yobhedu kwi-insulating layer. Kwi-design ye-multi-layer, emva koko ibophelelwe kuluhlu lwangaphakathi. Zikwasetyenziselwa njengesigqubuthelo sokukhusela ukugquma isiphaluka ukusuka eluthulini kunye nomswakama, kunye nokunciphisa uxinzelelo ngexesha le-flexure, i-foil yobhedu yenza i-conductive layer.

Kwezinye iisekethe eziguquguqukayo, iinqununu eziqinileyo ezenziwe nge-aluminium okanye i-stainless steel zisetyenzisiweyo, ezinokubonelela ngokuzinza kwe-dimensional, ukubonelela ngenkxaso yomzimba yokubekwa kwamacandelo kunye neengcingo, kunye nokukhulula uxinzelelo. I-adhesive ibophelela icandelo eliqinileyo kwisekethe eguquguqukayo. Ukongezelela, enye into esetyenziswayo ngamanye amaxesha kwiisekethe eziguquguqukayo, okuyi-adhesive layer, eyenziwa ngokugubungela amacala amabini efilimu yokukhusela nge-adhesive. I-adhesive laminates ibonelela ngokukhuseleka kokusingqongileyo kunye ne-electronic insulation, kunye nokukwazi ukuphelisa ifilimu enye encinci, kunye nokukwazi ukubopha amanqwanqwa amaninzi kunye neengqimba ezimbalwa.

Kukho iintlobo ezininzi zezinto zefilimu ezikhuselayo, kodwa ezona ziqhelekileyo zisetyenziswa yi-polyimide kunye ne-polyester. Phantse i-80% yabo bonke abavelisi beesekethe eziguquguqukayo e-United States basebenzisa izinto zefilimu ye-polyimide, kwaye malunga ne-20% basebenzisa izixhobo zefilimu ye-polyester. Izinto zePolyimide zinokutsha, ubungakanani bejometri obuzinzile kwaye bunamandla aphezulu okukrazula, kwaye banamandla okumelana nobushushu be-welding, i-polyester, eyaziwa ngokuba yi-polyethylene double phthalates (i-Polyethyleneterephthalate ekubhekiselwa kuyo njenge: PET), iipropati zayo zomzimba zifana ne-polyimides, ine-dielectric constant esezantsi, ifunxa ukufuma okuncinci, kodwa ayixhathisi kumaqondo obushushu aphezulu. I-Polyester inendawo yokunyibilika ye-250 ° C kunye neqondo lokushisa lokutshintsha kweglasi (Tg) ye-80 ° C, ethintela ukusetyenziswa kwabo kwizicelo ezifuna i-welding ebanzi yokuphela. Kwizicelo zokushisa eziphantsi, zibonisa ukuqina. Nangona kunjalo, zifanelekile ukuba zisetyenziswe kwiimveliso ezinje ngeefowuni kunye nezinye ezingadingi kuvezwa kwindawo enzima. Ifilimu ye-Polyimide yokugquma idla ngokudityaniswa ne-polyimide okanye i-acrylic adhesive, i-polyester insulating material idityaniswa ngokubanzi kunye ne-polyester adhesive. Inzuzo yokudibanisa kunye nempahla eneempawu ezifanayo ingaba nokuzinza kwe-dimensional emva kwe-welding eyomileyo okanye emva kwemijikelezo emininzi yokulambisa. Ezinye iipropathi ezibalulekileyo kwi-adhesives yi-dielectric ephantsi engaguqukiyo, ukuxhathisa okuphezulu kwe-insulation, ubushushu bokuguqulwa kweglasi ephezulu kunye nokufunxa okuphantsi komswakama.

2. Umqhubi

I-foil yobhedu ifanelekile ukusetyenziswa kwiisekethe eziguquguqukayo, ingaba yi-Electrodeposited (ED), okanye i-plated. Ifoyile yobhedu enedeposition yombane inomphezulu omenyezelayo kwelinye icala, ngelixa umphezulu welinye icala ibuthuntu kwaye ibuthuntu. Yimpahla eguquguqukayo enokwenziwa kubunzima obuninzi kunye nobubanzi, kwaye icala elibuthuntu le-ED yefoyile yobhedu ihlala iphathwa ngokukodwa ukuphucula amandla ayo okubopha. Ukongeza kokuguquguquka kwayo, i-foil yobhedu ekhutshiweyo nayo ineempawu ezinzima kwaye zigudileyo, ezifanelekileyo kwizicelo ezifuna ukugoba okuguquguqukayo.

3. Ukuncamathelisa

Ukongezelela ekusetyenzisweni ukudibanisa ifilimu ekhuselayo kwizinto eziphathekayo, i-adhesive ingasetyenziselwa njengoluhlu lokugubungela, njengengubo yokukhusela, kunye nokugubungela. Umahluko omkhulu phakathi kwezi zibini zilele kwisicelo esisetyenzisiweyo, apho i-cladding ibophelelwe kwifilimu yokugquma i-insulation kukwenza isiphaluka esakhiwe nge-laminated. Itekhnoloji yoshicilelo lwesikrini esetyenziselwa ukugquma isincamathelisi. Ayizizo zonke i-laminates eziqulethe i-adhesives, kwaye i-laminates ngaphandle kwe-adhesives iphumela kwiisekethe ezincinci kunye nokuguquguquka okukhulu. Xa kuthelekiswa nesakhiwo se-laminated esekelwe kwi-adhesive, ine-conductivity engcono ye-thermal. Ngenxa yesakhiwo esibhityileyo se-non-adhesive flexible circuit, kwaye ngenxa yokupheliswa kokumelana ne-thermal ye-adhesive, ngaloo ndlela kuphuculwe ukuqhutyelwa kwe-thermal, inokusetyenziswa kwindawo yokusebenza apho isiphaluka esiguquguqukayo esisekelwe kwi-adhesive structure elaminethiweyo. ayinakusetyenziswa.

Unyango lwangaphambi kokubeleka

Kwinkqubo yokuvelisa, ukuze kuthintelwe kakhulu isiphaluka esifutshane esivulekileyo kwaye kubangele isivuno esiphantsi kakhulu okanye ukunciphisa ukomba, ikhalenda, ukusika kunye nezinye iingxaki zenkqubo erhabaxa ezibangelwa yi-FPC board scrap, iingxaki zokuzaliswa kwakhona, kunye nokuvavanya indlela yokukhetha imathiriyeli ukufezekisa okona kulungileyo. iziphumo zokusetyenziswa kwabathengi beebhodi zeesekethe eziguquguqukayo, unyango lwangaphambili lubaluleke kakhulu.

Unyango lwangaphambili, mithathu imiba ekufuneka ijongwe, kwaye le miba mithathu igqityezelwa ziinjineli. Eyokuqala luvavanyo lobunjineli bebhodi ye-FPC, ikakhulu ukuvavanya ukuba ibhodi ye-FPC yomthengi inokuveliswa, ingaba umthamo wemveliso wenkampani unokuhlangabezana neemfuno zebhodi yomthengi kunye neendleko zeyunithi; Ukuba uvavanyo lweprojekthi lugqithisiwe, inyathelo elilandelayo kukulungiselela imathiriyeli ngokukhawuleza ukuhlangabezana nokunikezelwa kwezinto eziluhlaza kwikhonkco nganye yemveliso. Ekugqibeleni, injineli kufuneka: Umzobo wesakhiwo se-CAD somthengi, idatha yomgca we-gerber kunye namanye amaxwebhu obunjineli acutshungulwa ukuze ahambelane nommandla wemveliso kunye neenkcukacha zemveliso yezixhobo zemveliso, kwaye emva koko imizobo yemveliso kunye ne-MI (ikhadi lenkqubo yobunjineli) kunye nezinye izinto. ithunyelwe kwisebe lemveliso, ulawulo lwamaxwebhu, ukuthenga kunye namanye amasebe ukungena kwinkqubo yokuvelisa yesiqhelo.
