Imithetho yokuklama kanye nezinyathelo zokuqapha ze-Rigid Flex PCB

Idizayini ye-PCB eguquguqukayo eqinile iyinkimbinkimbi kakhulu kunokwakheka kwe-PCB yendabuko, futhi kunezindawo eziningi okufanele uzinake.Ikakhulukazi, indawo yoguquko eqinile eguquguqukayo, kanye nezintambo ezihambisanayo, ukuklama kwembobo, konke kudinga ukulandela izidingo zemithetho yokuklama ehambisanayo.

1. Ngokusebenzisa imbobo isikhundla

Endabeni yokusetshenziswa okuguquguqukayo, ikakhulukazi lapho ipuleti elithambile livame ukugoba, izimbobo ezidlula epuleti elithambile kufanele zigwenywe ngangokunokwenzeka, okulula ukulinyazwa nokuqhekeka.Kodwa-ke, izimbobo zingafakwa endaweni yokuqinisa ibhodi elithambile, kodwa umugqa onqenqemeni wendawo yokuqinisa kufanele futhi ugwenywe.Ngakho-ke, ekwakhiweni kwe-PCB eguquguqukayo eqinile, lapho umba, kubalulekile ukugwema ibanga elithile ukusuka endaweni ehlanganisiwe.

2. Idizayini yephedi nange-

Lapho iphedi nangendlela ihlangabezana nezidingo zikagesi, inani eliphezulu lizotholakala.Ukuxhumana phakathi kwephedi ne-conductor kusebenzisa ulayini woshintsho olushelelayo ukuze kugwenywe i-engeli engakwesokudla.Iphedi elizimele kufanele lengezwe ngezinzwane ukuze kuqiniswe umsebenzi wokusekela.

3. Ukwakhiwa kwezintambo

Endaweni eguquguqukayo, uma kunemigqa ezingqimbeni ezihlukene, zama ukugwema umugqa owodwa kungqimba olungaphezulu kanye nomunye umugqa ongaphansi.Ngale ndlela, lapho ibhodi eliguquguqukayo ligobile, ukucindezeleka kwezingqimba ezingenhla nezingezansi zeshidi lethusi akuhambisani, okulula ukubangela ukulimala komshini emgqeni.Esikhundleni salokho, kufanele inyakaziswe futhi izindlela kufanele ziwele.

4. I-Copper laying design

Ngokugoba okuguquguqukayo kwepuleti eliguquguqukayo eliqinisiwe, isakhiwo esihle kakhulu isakhiwo semeshi.Kodwa ngokulawulwa kwe-impedance noma ezinye izinhlelo zokusebenza, ikhwalithi kagesi yesakhiwo senethiwekhi ayigculisi.Ngakho-ke, umklami udinga ukwenza isinqumo esiphusile sokuthi uzosebenzisa ishidi lethusi lenethiwekhi noma ithusi eliqinile ngokuvumelana nezidingo zokuklama.

5. Ibanga phakathi komgodi wokubhoboza neshidi lethusi

Leli banga libhekisela ebangeni eliphakathi kwembobo neshidi lethusi.Siyibiza ngokuthi "ibanga le-hole copper".Izinto eziguquguqukayo ze-PCB zihlukile kulezo ze-PCB eqinile, ukuze kube nzima ukubhekana nebanga lethusi lembobo eqinile.Ngokuvamile, ibanga lethusi lembobo elijwayelekile kufanele libe ngu-10mil.

6. Idizayini yendawo ehlanganisiwe eguquguqukayo eqinile

Endaweni ehlangene eguquguqukayo eqinile, i-PCB eguquguqukayo idizayinelwe kangcono ukuxhuma ne-PCB eqinile phakathi kwesitaki.I-PCB eguquguqukayo ngembobo endaweni ehlangene eguquguqukayo eqinile ithathwa njengembobo engcwatshiwe.
