Ukuguquguquka kweeBhodi zeRigid-Flex ekuHlaleni iiMpawu eziPhakamileyo

Yazisa:

Kule bhlog, siza kuphonononga ukuguquguquka kweebhodi eziguquguqukayo kunye nokukwazi kwazo ukuphatha imiqondiso enesantya esiphezulu.

Kwihlabathi lanamhlanje elihamba phambili ngetekhnoloji, apho izixhobo zombane zisiba ncinci, zikhaphukhaphu, kwaye zintsonkothe ​​ngakumbi, imfuno yeebhodi zesekethe eziguquguqukayo kunye nesantya esiphezulu (PCBs) iyaqhubeka nokukhula.Iibhodi ze-Rigid-flex ziye zavela njengesisombululo esisebenzayo esidibanisa iingenelo ze-PCB eziqinileyo kunye neziguquguqukayo, ezenza zibe zilungele ukufumana iimpawu zesantya esiphezulu.

Icandelo 1: Ukuqonda iiBhodi zeRigid-Flex

I-Rigid-flex luhlobo oluxubileyo lwe-PCB edibanisa iileya zezinto eziqinileyo neziguquguqukayo.Ezi bhodi zibandakanya iisekethe eziguquguqukayo ezidityanisiweyo kunye namacandelo aqinileyo, ukubonelela zombini ukuzinza kunye nokuguquguquka.Ukudityaniswa kwamacandelo aqinileyo kunye aguquguqukayo avumela ibhodi ukuba igobe okanye igobe njengoko ifunekayo ngaphandle kokuchaphazela ukusebenza kwayo.

Icandelo lesi-2: Ukuhanjiswa koMqondiso wesantya esiphezulu

Iimpawu zesantya esiphezulu zitshintsha ngokukhawuleza izibonakaliso zombane ezidlula i-frequency threshold ethile.Le miqondiso ifuna ingqalelo ekhethekileyo ngexesha loyilo lwePCB kunye noyilo ukunqanda imiba yemfezeko yomqondiso efana ne-crosstalk, ukungahambelani kwe-impedance, kunye nokuphazamiseka komqondiso.Iibhodi ze-Rigid-flex zineenzuzo ezizodwa ekuqhubeni izibonakaliso zesantya esiphezulu ngenxa yokuguquguquka kwazo kunye nomgama omfutshane wokuhambisa umqondiso.

Icandelo lesi-3: Iingqwalasela zoyilo oluqinileyo-oluguquguqukayo lweempawu zesantya esiphezulu

3.1 Iimpedance elawulwayo:
Ukugcina i-impedance elawulwayo ibalulekile kwimfezeko yomqondiso wesantya esiphezulu.Iibhodi eziguquguqukayo eziqinileyo zivumela ulawulo olungcono lwe-impedance kuba iinxalenye eziguqukayo zinokuyilwa kunye neejometri zomkhondo kunye nobubanzi obuchanekileyo.Oku kuvumela utshintsho oluncinci lwendlela yokulandela umkhondo weempawu, ukuqinisekisa ukungabikho okungaguqukiyo kuyo yonke ibhodi.

3.2 Ukuhanjiswa komqondiso kunye nokupakishwa komgangatho:
Ukuhanjiswa komqondiso okufanelekileyo kunye nokupakishwa kweengqimba kubalulekile ekunciphiseni i-crosstalk yesiginali kunye nokufezekisa ukusebenza kakuhle.Iibhodi eziguquguqukayo eziguquguqukayo zivumela ukubekwa okuguquguqukayo kweempawu zeempawu zesantya esiphezulu, ngaloo ndlela zinciphisa umgama wokuhambisa kunye nokunciphisa intsebenziswano yesignali engafunekiyo.Ukongezelela, ukukwazi ukupakisha iileya ezininzi ngaphakathi kwefom yefom edibeneyo ivumela ukwahlula okusebenzayo kwamandla kunye neenqwelomoya zomhlaba, ukuqinisa ngakumbi ukunyaniseka komqondiso.

3.3 I-EMI kunye nokunciphisa i-crosstalk:
Ukuphazamiseka kwe-Electromagnetic (EMI) kunye ne-crosstalk yimiceli mngeni eqhelekileyo xa uphethe imiqondiso enesantya esiphezulu.Inzuzo yeebhodi ezingqongqo-eziguquguqukayo kukudibaniswa kokukhusela kunye nokulungelelaniswa okufanelekileyo kwendiza yomhlaba, okunciphisa umngcipheko we-EMI kunye ne-crosstalk.Oku kuqinisekisa ukuba umqondiso uhlala uzinzile kwaye ukhululekile ukuphazamiseka, ukuphucula ukusebenza kwenkqubo jikelele.

Icandelo lesi-4: Izibonelelo kunye nokusetyenziswa kweebhodi ze-high-speed signal rigid-flex board

4.1 Uyilo olugcina indawo:
Iiphaneli ze-Rigid-flex zineenzuzo ezibalulekileyo kwizicelo apho indawo iyancipha.Ukukwazi kwabo ukugoba kunye nokuziqhelanisa nendawo ekhoyo kuvumela ukusetyenziswa ngokufanelekileyo kwendawo, kubenza balungele izixhobo zombane ezihlangeneyo.

4.2 Ukuthembeka kunye noKuhlala ixesha elide:
Iibhodi eziguquguqukayo eziguquguqukayo zibonelela ngokuthembeka okukhulu kuneePCB zemveli eziqinileyo ngenxa yokubalwa koqhagamshelo oluncitshisiweyo kunye namanqaku anokusilela.Ukongeza, ukungabikho kweziqhagamshelo kunye neentambo zeribhoni kunciphisa umngcipheko wokuthotywa komqondiso kunye nokuqinisekisa ukuqina kwexesha elide.

4.3 Usetyenziso:
Iibhodi ze-Rigid-flex zisetyenziswa ngokubanzi kumashishini ahlukeneyo, kuquka i-aerospace, izixhobo zonyango, i-electronics yabathengi kunye neemoto.Ziyiyokuqala ukhetho lwezicelo apho ubungakanani, ubunzima kunye nokuthembeka kubaluleke kakhulu kwaye apho kufuneka ukuhanjiswa komqondiso wesantya esiphezulu.

Ukuququmbela:

Njengoko imfuno yokuhanjiswa kwesignali yesantya esiphezulu iqhubeka ikhula, iibhodi eziqinileyo-flex ziye zaba sisisombululo esisebenza ngeendlela ezininzi.Indibaniselwano yabo ekhethekileyo yokuguquguquka, uyilo lokugcina indawo kunye neempawu zengqibelelo yomqondiso zibenza zilungele ukufumana izibonakaliso zesantya esiphezulu.Ngokudibanisa i-impedance elawulwayo, umzila wesignali osebenzayo kunye neendlela ezifanelekileyo zokunciphisa i-EMI / crosstalk, iibhodi ezingqongqo-eziguquguqukayo ziqinisekisa ukusebenza okuthembekileyo kunye nokufanelekileyo kwiintlobo ezahlukeneyo zezicelo.
