Ikibaho cya Rigid-flex: ingingo zingenzi mugutunganya no kumurika.

Mugutunganya imbaho ​​zikomeye zumuzunguruko, ingorane zingenzi nuburyo bwo kugera kanda neza kumyanya yibibaho. Kugeza ubu, ibi biracyari ibintu abakora PCB bakeneye kwitondera byumwihariko. Hasi, Capel azaguha intangiriro irambuye kubintu byinshi bikeneye kwitabwaho.

Rigid Flexible PCB Substrate na Prepreg Lamination: Ibitekerezo byingenzi byo kugabanya Warpage no kugabanya ubushyuhe bwumuriro

Waba ukora substrate lamination cyangwa primaire yoroheje ya prereg, kwitondera kumyenda no kuboha imyenda y'ibirahure ni ngombwa. Kwirengagiza ibi bintu bishobora gutuma ubushyuhe bwiyongera hamwe nintambara. Kugirango hamenyekane ibisubizo byiza cyane bivuye mubikorwa byo kumurika, hagomba kwitonderwa kuriyi ngingo. Reka twinjire mubisobanuro byintambara yintambara no kuboha, hanyuma dushakishe inzira zifatika zo kugabanya ubushyuhe bwumuriro no kugabanya intambara.

Substrate lamination na prereg lamination nubuhanga busanzwe mubikorwa, cyane cyane mugukora imbaho ​​zacapwe zicapye (PCBs), ibikoresho bya elegitoroniki nibikoresho byinshi. Ubu buryo bukubiyemo guhuza ibice hamwe kugirango bikore ibicuruzwa bikomeye kandi bikora. Mubitekerezo byinshi byo gutsindira neza, icyerekezo cyimyenda yikirahure mumyenda no kuboha bigira uruhare runini.

Intambara hamwe nubudodo bivuga ibyerekezo bibiri byingenzi bya fibre mubikoresho bikozwe mubitambaro nkibirahure. Icyerekezo cyintambara muri rusange kigenda kibangikanye nuburebure bwumuzingo, mugihe icyerekezo cya weft gikora perpendicular kuri warp. Icyerekezo kirakomeye kuko kigena ibikoresho byubukanishi, nkimbaraga zingutu hamwe nuburinganire bwimiterere.

Mugihe cyo gukuramo lamination cyangwa prereg lamination, guhuza neza hamwe no guhuza imyenda y'ibirahuri ni ngombwa kugirango ukomeze ibikoresho bya tekinike byifuzwa byanyuma. Kunanirwa guhuza neza ibyerekezo bishobora kuvamo uburinganire bwimiterere no kongera ibyago byintambara.

Guhangayikishwa nubushyuhe ni ikindi kintu gikomeye ugomba gusuzuma mugihe cyo kumurika. Guhangayikishwa nubushuhe ni imbaraga cyangwa deformasiyo ibaho mugihe ikintu cyatewe nimpinduka zubushyuhe. Irashobora gukurura ibibazo bitandukanye birimo kurwana, gusibanganya, ndetse no kunanirwa kwa mashini byubatswe.

Kugirango ugabanye ubushyuhe bwumuriro no kwemeza inzira yo kumurika neza, ni ngombwa gukurikiza amabwiriza amwe. Mbere na mbere, menya neza ko imyenda y'ibirahure ibitswe kandi igakorerwa ahantu hagenzurwa n'ubushyuhe kugirango ugabanye itandukaniro ry'ubushyuhe hagati y'ibintu n'inzira yo kumurika. Iyi ntambwe ifasha kugabanya ibyago byo kurwara bitewe no kwaguka gutunguranye cyangwa kugabanuka.

Byongeye kandi, igipimo cyo gushyushya no gukonjesha mugihe cyo kumurika kirashobora kurushaho kugabanya ibibazo byumuriro. Ikoranabuhanga rituma ibikoresho bigenda bihinduka buhoro buhoro ihindagurika ryubushyuhe, bikagabanya ibyago byo guhindagurika cyangwa guhinduka.

Rimwe na rimwe, birashobora kuba byiza gukoresha uburyo bwo kugabanya ubushyuhe bwumuriro nko gukira nyuma ya lamination. Inzira ikubiyemo guhindura imiterere ya laminated kugirango igenzurwe kandi buhoro buhoro ubushyuhe bwo kugabanya ibibazo byose bisigaye byubushyuhe. Ifasha kugabanya page, yongerera imbaraga urwego kandi ikongerera ubuzima bwibicuruzwa byanduye.

Usibye ibi bitekerezo, ni ngombwa kandi gukoresha ibikoresho byiza no gukurikiza tekinike nziza yo gukora mugihe cyo kumurika. Guhitamo imyenda y'ibirahure yo mu rwego rwohejuru hamwe nibikoresho bihuza byerekana neza imikorere myiza kandi bikagabanya ingaruka ziterwa no guhangayika.

Byongeye kandi, gukoresha tekinoroji yo gupima neza kandi yizewe, nka laser profilometrie cyangwa ibipimo byerekana, birashobora gutanga ubushishozi bwimbaraga zintambara hamwe nurwego rwibibazo byubatswe. Gukurikirana buri gihe ibyo bipimo bituma ihinduka kandi ikosorwa mugihe gikenewe kugirango ubuziranenge bwifuzwa.

Ikintu cyingenzi ugomba gusuzuma muguhitamo ibikoresho bikwiye kubikorwa bitandukanye nubunini nubukomezi bwibikoresho.

Ibi ni ukuri cyane kubibaho bikomeye bigomba kuba bifite umubyimba runaka no gukomera kugirango ukore neza kandi urambe.

Igice cyoroshye cyibibaho bigoye cyane ni gito cyane kandi ntigifite umwenda wikirahure. Ibi bituma byoroha kubidukikije nubushyuhe. Kurundi ruhande, igice gikomeye cyinama giteganijwe kuguma gihamye uhereye kubintu nkibyo byo hanze.

Niba igice gikomeye cyinama kidafite umubyimba runaka cyangwa gukomera, itandukaniro ryuburyo rihinduka ugereranije nigice cyoroshye rishobora kugaragara. Ibi birashobora gutera ubwoba bukabije mugihe cyo gukoresha, bishobora kugira ingaruka mbi muburyo bwo kugurisha hamwe nibikorwa rusange byubuyobozi.

Ariko, iri tandukaniro rishobora kugaragara nkaho ridafite akamaro niba igice gikomeye cyinama gifite urwego runaka rwubugari cyangwa gukomera. Nubwo igice cyoroshye gihinduka, uburinganire bwubuyobozi ntibuzagira ingaruka. Ibi byemeza ko ikibaho gikomeza gushikama kandi cyizewe mugihe cyo kugurisha no gukoresha.

Birakwiye ko tumenya ko mugihe umubyimba nubukomezi ari ngombwa, hariho imipaka yubunini bwiza. Niba ibice bibyibushye cyane, ntabwo ikibaho kizaba kiremereye gusa, ariko nanone kizaba kidasanzwe. Kubona uburinganire bukwiye hagati yubugari, gukomera nuburemere nibyingenzi kugirango habeho gukora neza no gukora neza.

Ubushakashatsi bwagutse bwakozwe kugirango hamenyekane uburebure bwiza kubibaho bikomeye. Ubu bushakashatsi bwerekana ko umubyimba wa mm 0.8 kugeza kuri mm 1.0 ukwiye. Muri uru rwego, ikibaho kigera kurwego rwifuzwa rwubugari no gukomera mugihe ugifite uburemere bwemewe.

Muguhitamo ikibaho gikomeye hamwe nubunini bukwiye nubukomere, ababikora nabakoresha barashobora kwemeza ko ikibaho kizakomeza kuba cyiza kandi gihamye nubwo ibintu bitandukanye. Ibi bitezimbere cyane ubwiza rusange nubwizerwe bwibikorwa byo kugurisha no kuboneka kwinama.

Ibintu bigomba kwitabwaho mugihe cyo gutunganya no guhuza:

Ikibaho gikomeye cyumuzunguruko ni ihuriro ryibintu byoroshye kandi byoroshye. Uku guhuza guhuza ibyiza byombi, bifite byombi guhuza ibikoresho bikomeye kandi bikomeye. Ibikoresho bidasanzwe bisaba tekinoroji yihariye yo gutunganya kugirango yizere imikorere myiza.

Iyo uvuze uburyo bwo kuvura idirishya ryoroshye kuriyi mbaho, gusya ni bumwe muburyo busanzwe. Muri rusange, hari uburyo bubiri bwo gusya: haba gusya mbere, hanyuma gusya byoroshye, cyangwa nyuma yo kurangiza inzira zose zabanjirije iyi no kubumba bwa nyuma, koresha gukata lazeri kugirango ukureho imyanda. Guhitamo uburyo bubiri biterwa nuburyo nubunini bwikibaho cyoroshye kandi gikomeye.

Niba idirishya ryoroshye ryabanje gusya kugirango tumenye neza ko gusya ari ngombwa. Gusya bigomba kuba byuzuye, ariko ntibibe bito cyane kuko ntibigomba kugira ingaruka kubikorwa byo gusudira. Kugirango bigerweho, abashakashatsi barashobora gutegura amakuru yo gusya kandi barashobora kubanza gusya kumadirishya yoroheje. Binyuze muri ibyo, guhindura ibintu birashobora kugenzurwa, kandi inzira yo gusudira ntabwo igira ingaruka.

Kurundi ruhande, niba uhisemo kutasya idirishya ryoroshye, gukata laser bizagira uruhare. Gukata lazeri nuburyo bwiza bwo gukuraho imyanda yoroheje. Ariko, witondere ubujyakuzimu bwo gukata lazeri FR4. Ukeneye kunonosora ibipimo byo guhagarika bikwiye kugirango ugabanye neza Windows yoroheje.

Kugirango uhindure ibipimo byo guhagarika, ibipimo bikoreshwa mukuvuga ibyoroshye byoroshye hamwe nibibaho bikomeye ni ingirakamaro. Iterambere ryuzuye rirashobora kwemeza ko igitutu gikwiye gikoreshwa mugihe cyumuvuduko, bityo bigakora ikibaho cyiza kandi gikomeye.

Ibimaze kuvugwa haruguru nibintu bitatu bikeneye kwitabwaho bidasanzwe mugihe cyo gutunganya no gukanda imbaho ​​zikomeye za flex circuit. Niba ufite ibibazo byinshi kubyerekeye imbaho ​​zumuzunguruko, nyamuneka utugire inama. Capel yakusanyije imyaka 15 yuburambe mu nganda zumuzunguruko, kandi tekinoroji yacu mubijyanye na platifike ya flex irakuze rwose.
