Ukuba nokwenzeka kweRigid-flex PCB Prototype ye-Wireless Sensor Networks

Yazisa:

Ngokuvela kweenethiwekhi zenzwa ezingenazintambo (i-WSNs), imfuno yeesekethe ezisebenzayo kunye ne-compact iyaqhubeka ikhula. Ukuphuhliswa kwee-PCB eziguquguqukayo eziguquguqukayo kwakuyinkqubela enkulu kwishishini le-electronics, evumela ukudalwa kweebhodi zeesekethe eziguquguqukayo ezinokudibaniswa kunye neengxenye eziqinileyo.Kwesi sithuba sebhlog, siza kujonga ngakumbi ukuba kuyenzeka na ukwenza i-PCBs eqinile-eguquguqukayo yothungelwano lwesivamvo esingenazingcingo, kwaye siphonononge izibonelelo kunye nemiceli mngeni eyayanyaniswa nobu buchwepheshe butsha.

1. Yintoni ibhodi engqongqo-flex?

I-Rigid-flex PCBs zizakhiwo ezixubileyo ezenziwe ngamacandelo aguquguqukayo kwaye aqinile. Ezi bhodi zakhiwe ukusuka indibanisela substrate imathiriyeli bhetyebhetye, umaleko ancamatheleyo, kunye namacandelo PCB ngqongqo. Xa kuthelekiswa ne-PCB yemveli engqongqo okanye ebhetyebhetye, iibhodi zesekethe zixinene kakhulu, zihlala zihlala ziqinile kwaye zithembekile.

2. Iinzuzo ezinokuthi zibe kho zothungelwano lwesivamvo esingenazingcingo:

a) Ukusebenza kakuhle kwendawo: Iibhodi eziguquguqukayo eziguquguqukayo zineenzuzo ezizodwa ekusebenziseni indawo.Ngokudibanisa iindawo eziqinileyo kunye neziguquguqukayo, ezi bhodi zinokufakelwa kwizixhobo ezincinci kunye nezingaqhelekanga, ezizenza zibe zilungele uthungelwano lwenzwa engenazintambo, apho ukudibanisa kubaluleke kakhulu.

b) Ukuthembeka okuphuculweyo: Ukudibanisa izinto eziqinileyo kunye neziguquguqukayo kwibhodi enye kunciphisa inani lee-solder kunye nezixhumi.Ukuthembeka kunyuswa njengoko kukho iingongoma ezimbalwa zokungaphumeleli, ukunciphisa ithuba lomonakalo wesiphaluka ngenxa ye-vibration okanye ukuguquguquka kweqondo lokushisa.

c) Uphuculo lokuqina: Uthungelwano lwenzwa engenangcingo luhlala lusebenza kwindawo ezirhabaxa kwaye lufuna iisekethe ezirhabaxa.I-Rigid-flex PCBs inika ukuqina okufunekayo ukuqinisekisa ixesha elide le-wireless sensor nodes ngokubonelela ngokhuseleko olubalaseleyo kumswakama, uthuli kunye nezinye izinto zokusingqongileyo.

3. Imingeni ejongene noyilo lweprototype ye-wireless sensor network hardware kunye nebhodi yesoftware:

a) Uyilo oluntsonkothileyo: Inkqubo yoyilo lweebhodi eziguquguqukayo zintsonkothe ​​ngokwendalo kuneePCB zemveli.Ukuqinisekisa ukulungelelaniswa okufanelekileyo phakathi kwamacandelo aqinileyo kunye aguquguqukayo, ukuchaza i-radii ye-bend efanelekileyo, kunye nokulawula ukunyaniseka komqondiso weminye imingeni abaqulunqi kufuneka bajongane nayo.

b) Ukukhethwa kwezinto: Ukukhethwa kwezinto ezisetyenziswa kwiibhodi ezilukhuni-flex zidlala indima ebalulekileyo ekusebenzeni kwazo.Ukukhetha i-substrates efanelekileyo, i-adhesives, kunye ne-laminates ezinokumelana neemeko zokusingqongileyo apho i-wireless sensor network networks ibaluleke kakhulu, kodwa yongeza ubunzima kwinkqubo yeprototyping.

c) Iindleko zokwenziwa kwemveliso: Ngenxa yezinto ezinje ngemathiriyeli eyongezelelweyo, izixhobo ezikhethekileyo, kunye neenkqubo ezintsonkothileyo zokwenziwa, ixabiso lokwenziwa kweprototype ye-PCB eguquguqukayo elukhuni inokuba phezulu kune-PCB yemveli.Ezi ndleko kufuneka ziqwalaselwe kwaye zilinganiswe ngokuchasene nenzuzo yokusebenzisa ubuchule obuqinileyo obuguquguqukayo kuthungelwano lwesivamvo esingenazingcingo.

4. Yoyisa imiceli mngeni:

a) Indlela yokusebenzisana: Iprototyping yePCB eguquguqukayo ye-WSN ifuna intsebenziswano esondeleyo phakathi kwabayili, iinjineli kunye nabavelisi.Ngokubandakanya bonke abachaphazelekayo ukusuka kumanqanaba okuqala, ukuntsonkotha koyilo, ukukhethwa kwezinto eziphathekayo kunye nemingeni yokuvelisa kunokulungiswa ngokulula ngokufanelekileyo.

b) Inkqubo yokuphindaphinda: Ngenxa yobunzima beebhodi ze-rigid-flex, uphindaphindo oluninzi lunokufuneka ukuze kuphunyezwe ukusebenza okufunekayo kunye nokuthembeka.Kubalulekile ukuba ulungiselele iqondo lolingo kunye neempazamo ngexesha lesigaba sokwenza umzobo.

c) IsiKhokelo seeNgcali: Ukubhalisa uncedo lweengcali ezinamava kwintsimi yeprototyping ye-PCB eguquguqukayo (efana noyilo lobuchwephesha kunye neenkonzo zokuvelisa) kunokuba luncedo kakhulu.Ubuchwephesha babo bunokunceda ekusombululeni iingxaki ezintsonkothileyo kunye nokuqinisekisa inkqubo eyimpumelelo yokufaka isicelo se-WSN prototyping.

Ukuququmbela:

IiPCB eziguquguqukayo eziguquguqukayo zinamandla okutshintsha ngokupheleleyo imbonakalo yomhlaba yothungelwano lwenzwa yocingo.Le teknoloji intsha ibonelela ngeenzuzo ezininzi, kubandakanya ukusebenza kakuhle kwendawo, ukuthembeka okuphuculweyo kunye nokuqina. Nangona kunjalo, iprototyping ye-PCB eguquguqukayo yothungelwano lwenzwa engenazingcingo ijongana nemiceli mngeni ethile, enjengobunzima boyilo, ukukhetha izinto kunye neendleko zokuvelisa. Nangona kunjalo, ngokuthatha indlela yokusebenzisana, ukusebenzisa inkqubo ephindaphindwayo, kunye nokufuna isikhokelo seengcali, le mingeni inokoyiswa. Ngokucwangciswa okufanelekileyo kunye nokwenziwa, iprototyping ye-PCB eguquguqukayo yothungelwano lwenzwa engenazingcingo inokuvula indlela yezixhobo eziphucukileyo nezisebenzayo ze-IoT kwixesha elizayo.
