Niki Rigid Flex PCB Stackup

Muri iki gihe isi yihuta cyane yikoranabuhanga, ibikoresho bya elegitoronike biragenda bitera imbere kandi byoroshye.Kugirango uhuze ibyifuzo byibi bikoresho bigezweho, imbaho ​​zumuzingo zacapwe (PCBs) zikomeza guhinduka no gushiramo tekinike nshya yo gushushanya.Bumwe muri ubwo buryo bwikoranabuhanga ni flex pcb stackup, itanga ibyiza byinshi mubijyanye no guhinduka no kwizerwa.Iyi mfashanyigisho yuzuye izasesengura icyerekezo gikomeye cyumuzunguruko wumuzunguruko icyo aricyo, inyungu zacyo, nubwubatsi bwacyo.

Mbere yo kwibira muburyo burambuye, reka tubanze turebe ibyibanze bya PCB stackup ：

PCB stackup bivuga gahunda yuburyo butandukanye bwumuzunguruko muri PCB imwe.Harimo guhuza ibikoresho bitandukanye kugirango habeho imbaho ​​nyinshi zitanga amashanyarazi.Ubusanzwe, hamwe na PCB ikomeye cyane, ibikoresho bikomeye gusa bikoreshwa kubibaho byose.Ariko, hamwe no kumenyekanisha ibikoresho byoroshye, hagaragaye igitekerezo gishya-gikomeye-flex PCB stackup.

None, ni ubuhe buryo bukomeye laminate ikomeye?

Ikibaho gikomeye cya PCB ni ikibaho cyumuzunguruko uhuza ibikoresho bya PCB byoroshye kandi byoroshye.Igizwe no guhinduranya ibice bigoye kandi byoroshye, byemerera ikibaho kunama cyangwa guhindagurika nkuko bikenewe mugihe gikomeza uburinganire bwimiterere n'imikorere y'amashanyarazi.Uku guhuza kudasanzwe gukora PC-stackups ikomeye cyane ya porogaramu nziza aho ikoreshwa ahantu hagomba gukenerwa cyane kandi hagomba gukenerwa cyane, nk'imyenda ishobora kwambara, ibikoresho byo mu kirere, n'ibikoresho by'ubuvuzi.

Noneho, reka dusuzume ibyiza byo guhitamo PCB igizwe na elegitoroniki yawe.

Ubwa mbere, guhinduka kwayo kwemerera ikibaho guhuza ahantu hafunganye kandi bigahuza nuburyo budasanzwe, bikagabanya umwanya uhari.Ihinduka kandi rigabanya ubunini nuburemere bwibikoresho mugukuraho ibikenerwa guhuza hamwe ninsinga ziyongera.Byongeye kandi, kubura kw'abahuza bigabanya ingingo zishobora gutsindwa, kongera ubwizerwe.Byongeye kandi, kugabanya insinga biteza imbere uburinganire bwikimenyetso kandi bigabanya ibibazo bya electromagnetic (EMI).

Kubaka PCB yibitseho ibintu byinshi byingenzi ：

Mubisanzwe bigizwe nibice byinshi bikomeye byahujwe nuburyo bworoshye.Umubare wibice biterwa nuburyo bugoye bwo gushushanya umuzenguruko n'imikorere wifuza.Ibice bya Rigid mubisanzwe bigizwe na FR-4 isanzwe cyangwa ubushyuhe bwo hejuru cyane, mugihe ibice byoroshye ari polyimide cyangwa ibikoresho bisa byoroshye.Kugirango umenye neza amashanyarazi hagati yuburyo bukomeye kandi bworoshye, hakoreshwa ubwoko bwihariye bwo gufatira hamwe bita anisotropic conductive adhesive (ACA).Iyi miti itanga amashanyarazi hamwe nubukanishi, byemeza imikorere yizewe.

Kugirango usobanukirwe nuburyo bukomeye PCB ikurikirana, dore gusenyuka kwinzego 4 zubuyobozi bwa PCB:

Igice cyo hejuru:
Icyatsi cyo kugurisha icyatsi nicyiciro cyo gukingira gikoreshwa kuri PCB (Icapa ryumuzunguruko)
Igice cya 1 (Ikimenyetso Cyerekana):
Urufatiro rwumuringa hamwe na plaque yumuringa.
Igice cya 2 (Igice cyimbere / dielectric layer):
FR4: Iki nikintu gisanzwe gikoreshwa muri PCBs, gitanga ubufasha bwimashini no kwigunga amashanyarazi.
Igice cya 3 (Icyerekezo cya Flex):
PP: Polipropilene (PP) yometseho irashobora kurinda uburinzi bwumuzunguruko
Igice cya 4 (Icyerekezo cya Flex):
Igipfukisho cya PI: Polyimide (PI) ni ibintu byoroshye kandi birwanya ubushyuhe bikoreshwa nkigice cyo hejuru kirinda igice cya flex ya PCB.
Igipfukisho cya AD: tanga uburinzi kubintu byangirika byangiritse kubidukikije, imiti cyangwa ibishushanyo bifatika
Igice cya 5 (Igice cya Flex):
Urufatiro rwumuringa: Urundi rwego rwumuringa, rusanzwe rukoreshwa mubimenyetso byerekana ibimenyetso cyangwa gukwirakwiza ingufu.
Igice cya 6 (Icyerekezo cya Flex):
PI: Polyimide (PI) ni ibintu byoroshye kandi birwanya ubushyuhe bikoreshwa nkigice fatizo mugice cya PCB.
Igice cya 7 (Flex Layeri):
Urufatiro rwumuringa: Nyamara urundi rwego rwumuringa, rusanzwe rukoreshwa mubimenyetso byerekana ibimenyetso cyangwa gukwirakwiza ingufu.
Igice cya 8 (Icyerekezo cya Flex):
PP: Polypropilene (PP) ni ibintu byoroshye bikoreshwa mugice cya PCB.
Cowerlayer AD: tanga uburinzi kubintu byangirika byangiritse kubidukikije, imiti cyangwa ibishushanyo bifatika
Igipfukisho cya PI: Polyimide (PI) ni ibintu byoroshye kandi birwanya ubushyuhe bikoreshwa nkigice cyo hejuru kirinda igice cya flex ya PCB.
Igice cya 9 (Imbere Imbere):
FR4: Ikindi gice cya FR4 kirimo inkunga yinyongera yubukanishi no kwigunga amashanyarazi.
Igice cya 10 (Hasi Hasi):
Urufatiro rwumuringa hamwe na plaque yumuringa.
Hasi:
Icyatsi kibisi.

Nyamuneka menya ko kugirango usuzume neza kandi ushishoze neza, birasabwa kugisha inama umushinga wa PCB cyangwa uruganda rushobora gutanga isesengura rirambuye hamwe nibyifuzo ukurikije ibyo usabwa n'imbogamizi.

Muri make ：

Rigid flex PCB stackup nigisubizo gishya gihuza ibyiza byibikoresho bya PCB bikomeye kandi byoroshye.Guhinduka kwayo, guhuzagurika no kwizerwa bituma bikwiranye na porogaramu zitandukanye zisaba guhuza umwanya no kugoreka imbaraga.Gusobanukirwa ibyibanze bya rigid-flex stackups nubwubatsi bwabo birashobora kugufasha gufata ibyemezo byuzuye mugihe cyo gukora no gukora ibikoresho bya elegitoroniki.Mugihe ikoranabuhanga rikomeje gutera imbere, icyifuzo cya PCB gikomeye cyane ntikizabura kwiyongera, bigatuma iterambere ryiyongera muriki gice.
