Izikhokelo zoyilo loyilo lwebhodi yesekethe engqongqo-flex

Xa uyila ibhodi yesekethe engqongqo-flex, enye yezinto eziphambili ekufuneka ziqwalaselwe kukuhambisa umkhondo. Imikhondo kwibhodi yesekethe idlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokufanelekileyo kwamacandelo e-elektroniki.Kule posi yebhlog, siza kuxubusha izikhokelo zoyilo eziqhelekileyo zomzila kwiibhodi zesekethe eziqinileyo.

1. Landela ububanzi kunye nesithuba:

Ububanzi bomkhondo yinto ebalulekileyo ekunqumeni umthamo wayo wangoku wokuthwala kunye ne-impedance. Kuyacetyiswa ukuba kusetyenziswe imikhondo ebanzi yoqhagamshelo oluphezulu lwangoku ukuthintela ubushushu obugqithisileyo kunye nokusilela okunokwenzeka. Ngokukwanjalo, isithuba phakathi komkhondo kufuneka sanele ukunqanda ukuphazamiseka kwe-crosstalk kunye ne-electromagnetic interference (EMI). Umkhondo wobubanzi kunye nezikhokelo zezithuba zinokwahluka ngokuxhomekeke kwiimfuno ezithile zebhodi kunye namalungu ayo.

2. Umqondiso wemfezeko kunye nolawulo lokuthintela:

Ingqibelelo yomqondiso yingqwalasela ebalulekileyo kuyilo lwebhodi yesekethe. Iibhodi eziguquguqukayo eziqinileyo zihlala ziqulathe amacandelo aneemfuno ezahlukeneyo zokuthintela, ezifana ne-microstrip kunye neentambo zothumelo lwe-stripline. Kubalulekile ukugcina ukuhambelana kwe-impedance kuyo yonke inkqubo yomzila ukunciphisa ukubonakalisa umqondiso kunye nokuqinisekisa ukusebenza kakuhle. Izixhobo ezifana ne-impedance calculators kunye ne-software yokulinganisa inokunceda ukufezekisa ulawulo oluchanekileyo lwe-impedance.

3. Ukupakisha umaleko kunye neendawo ezigobayo:

Iibhodi zesekethe eziguquguqukayo zihlala ziqulunqwe ngamacandelo amaninzi, kubandakanywa iindawo eziqinileyo kunye neendawo eziguquguqukayo. Uyilo kunye nomzila weetrayisi kwiileya ezahlukeneyo kufuneka ziqwalaselwe ngononophelo ukuthintela ukuphazamiseka komqondiso kunye nokugcina ukuguquguquka kwebhodi. Kuyimfuneko ukuchonga iindawo apho ibhodi iya kugoba kwaye igweme ukubeka iimpawu ezibalulekileyo kule mimandla, njengoko ukugoba okugqithisileyo kunokubangela ukuba umkhondo uphuke okanye ungaphumeleli.

4. Iindlela ezimbini ezahlukeneyo:

Kuyilo lwanamhlanje lwe-elektroniki, izibini ezihlukeneyo zihlala zisetyenziselwa imiqondiso enesantya esiphezulu ukuqinisekisa ukuhanjiswa kwedatha ethembekileyo. Xa uhambisa izibini ezihlukeneyo kwiibhodi eziguquguqukayo eziguquguqukayo, kubalulekile ukugcina ubude obuhambelanayo kunye nesithuba phakathi kokulandelela ukugcina ingqibelelo yesignali. Nakuphi na ukungahambi kakuhle kunokubangela iimpazamo zexesha okanye ukuphazamiseka komqondiso, okuchaphazela ukusebenza ngokubanzi kwesekethe.

5. Ngoyilo kunye nokuphuma kwefeni:

Ii-Vias ziyinxalenye ebalulekileyo kuyilo lwebhodi yesekethe kuba zibonelela ngoqhagamshelo lombane phakathi kweeleya ezahlukeneyo. Ngokufanelekileyo ngokucwangcisa kunye neendlela zokukhupha abalandeli zinceda ukugcina imfezeko yomqondiso kunye nokuqinisekisa uqhagamshelwano oluthembekileyo. Kubalulekile ukunqanda ukubeka i-vias kufutshane kakhulu nesantya esiphezulu njengoko inokwazisa imbonakalo okanye ukungahambi kakuhle kokuphazamiseka.

6. I-EMI kunye nokuGrounding:

Ukuphazamiseka kwe-Electromagnetic (EMI) kunokuchaphazela kakubi ukusebenza kwezixhobo zombane. Ukunciphisa i-EMI, qiniseka ukuba unika ingqwalaselo kubuchule bokubeka phantsi komhlaba kwaye ngononophelo i-wiring yeendlela kufutshane nezinto ezinobuthathaka. Inqwelomoya eqinileyo yomhlaba inokusebenza njengekhaka kwaye inciphise i-EMI. Ngokuqinisekisa iindlela ezifanelekileyo zokumisa, ingxolo enokubakho kunye ne-crosstalk inokuncitshiswa, ngaloo ndlela iphucula ukusebenza ngokubanzi.

Isishwankathelo

Ukuyila ibhodi yesekethe ye-rigid-flex idinga ukuqwalaselwa ngokucophelela kwezinto ezahlukeneyo, kwaye ukulandelela umzila kuyinkalo ebalulekileyo echaphazela kakhulu ukusebenza ngokubanzi kunye nokuthembeka kwesekethe. Ngokulandela izikhokelo zoyilo eziqhelekileyo ezixoxwe kule post yebhlog, iinjineli zinokuqinisekisa imfezeko yophawu oluchanekileyo, ulawulo lwe-impedance, kunye nokunciphisa i-EMI, okukhokelela kuyilo oluphezulu kunye noluqilima lwebhodi yesekethe.I-Shenzhen Capel Technology Co.,Ltd.ivelisa engqongqo pcb flex kunye pcb bhetyebhetye ukususela ngo-2009 kwaye uneminyaka eli-15 amava projekthi kushishino pcb.
