Yeyiphi imingeni yoyilo eqhelekileyo xa usebenzisa ii-PCB eziguquguqukayo eziqinileyo?

Kule post yebhlog, siza kuphonononga imingeni yoyilo eqhelekileyo esijongene nayo xa sisebenza ngeePCB eziguquguqukayo kwaye sixoxe ngezicwangciso ezisebenzayo zokoyisa le mingeni.

Iibhodi zesekethe eziprintiweyo eziguquguqukayo (iiPCB) ziguqule ishishini le-elektroniki ngokunyusa ukuguquguquka koyilo, ukonga indawo kunye nokuqinisa ukuqina. Ezi PCBs engqongqo-flex zinika iingenelo ezinkulu ngakumbi xa zidityaniswe neendawo engqongqo kwibhodi enye. Nangona kunjalo, ukusebenzisa ii-PCB eziguquguqukayo eziguquguqukayo kwakhona kuza neseti yayo yemingeni yoyilo.

1. Iimfuno zokugoba kunye nokuphambuka:

Omnye wemingeni ephambili ekuyileni ii-PCB eziguquguqukayo kukuqinisekisa ukuba inxalenye eguquguqukayo inokumelana nokugoba okuphindaphindiweyo kunye nokugoba ngaphandle kokuchaphazela ukusebenza kwayo. Ukuhlangabezana nolu celomngeni, abaqulunqi kufuneka bakhethe izinto ezifanelekileyo, njengepolyimide, ezinamandla okugoba nezinokumelana noxinzelelo oluqatha lomatshini. Ukongeza, umgaqo kunye nokubekwa kwecandelo kufuneka kucwangciswe ngononophelo ukuthintela uxinzelelo olunokukhokelela ekungaphumeleli kwexesha.

2. Ukuthembeka konxibelelwano:

Ukuthembeka konxibelelwano kubalulekile kwiiPCB eziguquguqukayo eziguquguqukayo njengoko zifuna uqhagamshelo lombane olungaguqukiyo phakathi kweendawo ezomeleleyo neziguquguqukayo. Ukuqinisekisa ukuthembeka koqhagamshelo kufuna uqwalaselo olucokisekileyo lweendlela kunye nobuchule bokuphelisa. Ukugoba okubukhali, ukolula okugqithisileyo, okanye uxinzelelo ekudibaneni kufuneka kuphetshwe njengoko ezi zinokulwenza buthathaka umdibaniso kwaye zibangele ukusilela kombane. Abaqulunqi banokukhetha ubuchule obunje nge-teardrops, iipads ezinde, okanye imigca enqamlezileyo ukongeza ukomelela koqhakamshelwano.

3. Ulawulo lobushushu:

Ulawulo olufanelekileyo lwe-thermal lubalulekile kwiibhodi ezingqongqo-eziguquguqukayo zokuqinisekisa ukusebenza kakuhle kunye nokuthintela ukushisa. Ukuhlanganiswa kweendawo eziqinileyo kunye neziguquguqukayo kudala imingeni ekhethekileyo yokutshatyalaliswa kobushushu obusebenzayo. Abaqulunqi kufuneka baqwalasele izinto ezifana nokuchithwa kobushushu becandelo, umahluko kwi-coefficients yokwandisa i-thermal phakathi kwezinto eziqinileyo kunye neziguquguqukayo, kunye nesidingo se-thermal vias ukuhambisa ubushushu kude kwiindawo ezibalulekileyo. Ukulinganisa kwe-thermal kunye nokuhlalutya kunokunceda ukuchonga iindawo ezinokuthi zishushu kwaye zisebenzise izisombululo ezifanelekileyo ze-thermal.

4. Ukubekwa kwecandelo kunye nendlela:

Ukubekwa kunye nokuhanjiswa kwamacandelo kwii-PCB eziguquguqukayo ezilukhuni zifuna ukuqwalaselwa ngenyameko ngenxa yokusebenzisana phakathi kweendawo eziqinileyo kunye neziguquguqukayo. Abaqulunqi kufuneka baqwalasele ukugoba koomatshini kunye nokuguquguquka kweebhodi zeesekethe ngexesha lokudibanisa kunye nokusetyenziswa. Amacandelo kufuneka abekwe kwaye ahanjiswe ngendlela yokunciphisa amanqaku oxinzelelo, ukomeleza imfezeko yomqondiso, kunye nokwenza lula inkqubo yokuhlanganisa. Ukulinganisa okuphindiweyo kunye novavanyo kuqinisekisa ukubekwa kwecandelo kunye nendlela yokuphepha ukulahleka komqondiso ngokungeyomfuneko okanye ukusilela koomatshini.

5. Ukwenziwa kweMveliso kunye neNdibano entsonkothileyo:

Iibhodi ezi-Rigid-flex zinemveliso ephezulu kunye nobunzima bendibano kuneebhodi eziqinileyo zendabuko. Ukudityaniswa kweeleya ezininzi kunye nezixhobo kufuna ubuchule obukhethekileyo bokuvelisa kunye nezixhobo. Intsebenziswano phakathi kwabayili kunye nabavelisi ibalulekile ekuguquleleni ngempumelelo injongo yoyilo kwiimveliso ezenziweyo. Ukubonelela ngamaxwebhu acacileyo kunye neenkcukacha zoyilo, kubandakanywa nolwazi oluchanekileyo lokubeka, ukucaciswa kwezinto eziphathekayo kunye nezikhokelo zendibano, ukulungelelanisa inkqubo yokuvelisa kunye nendibano.

6. Umqondiso weMfezeko kunye neeNgqwalasela ze-EMI/EMC:

Ukugcina imfezeko yomqondiso kunye nokunciphisa ukuphazamiseka kwe-electromagnetic / ukuhambelana kombane (EMI/EMC) imingcipheko yingqwalasela ephambili yoyilo lweePCB eziguquguqukayo. Ukusondela kweendawo eziqinileyo kunye neziguquguqukayo zinokuzisa imiba yokudibanisa kunye ne-crosstalk. Ukucwangciswa ngokucokisekileyo kwendlela yomqondiso, ubuchule bokumisa, kunye nokusetyenziswa kokukhusela kunokuncedisa ukunciphisa le mingeni. Ukongeza, kufuneka uqinisekise ukuba ukhetha amacandelo afanelekileyo kunye nokusebenza kakuhle kwe-EMI kwaye uthobele imigangatho yeshishini kunye nezikhokelo.

Isishwankathelo

Ngelixa ii-PCB eziguquguqukayo ezingqongqo zibonelela ngeenzuzo ezininzi malunga nokuguquguquka koyilo kunye nokuqina, zikwabonisa imingeni yoyilo eyodwa. Ngokujongana nemiba enje ngeemfuno eziguquguqukayo, ukuthembeka konxibelelwano, ulawulo lobushushu, ukubekwa kwecandelo kunye nendlela, ubunzima bokuvelisa, kunye nokuthembeka komqondiso, abaqulunqi banokuyoyisa le mingeni kwaye basebenzise ngokupheleleyo amandla obuchwepheshe be-PCB eqinile. Ngokucwangcisa ngononophelo, intsebenziswano, kunye nokubambelela kwezona zenzo zilungileyo, iinjineli zinokwenza iimveliso ezinempumelelo ezithatha ithuba loyilo lwePCB elukhuni.
