Masiku ano zamagetsi zamakono zili ndi kufunikira kokulirapo kwa ma PCB amitundu yambiri

Padziko lamagetsi, Mabodi Osindikizidwa Ozungulira (PCBs) amatenga gawo lofunikira pakulumikiza magawo osiyanasiyana ndikuwonetsetsa kuti zikuyenda bwino.Kufunika kwa zida zing'onozing'ono, zogwira mtima kwambiri, zotsogola zaukadaulo kwadzetsa kukula kwakukulu kwaukadaulo wa PCB pazaka zambiri.Kupita patsogolo kumodzi kotere ndi PCB yamitundu yambiri, yomwe ikukhala yotchuka kwambiri mumagetsi amakono amakono.Blog iyi ikufuna kuwunikira kufunikira ndi ubwino wa ma PCB amitundu yambiri muzochitika zamakono zamakono.

Phunzirani za ma PCB ambiri.
Kuti mumvetsetse kufunikira kwa PCB yamitundu yambiri, munthu ayenera kumvetsetsa kapangidwe kake koyambira.Mosiyana ndi ma PCB amtundu umodzi kapena awiri osanjikiza, ma PCB amitundu yambiri amapangidwa ndi zigawo zingapo zazinthu zosiyanitsidwa ndi zida za dielectric.Zigawozi zimalumikizidwa ndi vias, zomwe zimalola kuti ma sign amagetsi aziyenda mosasunthika kudzera pa bolodi ladera.Chiwerengero cha zigawo chikhoza kuchoka pa zinayi mpaka khumi ndi ziwiri, malingana ndi zovuta za dera komanso zofunikira za chipangizocho.

Ubwino wamultilayer PCB:

1. Mapangidwe ang'onoang'ono: Ma PCB a Multilayer amathandizira opanga kupanga zida zamagetsi zocheperako komanso zazing'ono popanda kusokoneza magwiridwe antchito awo.Kutha kuyika zigawo zingapo molunjika kumathandizira kugwiritsa ntchito bwino malo ndipo ndikwabwino pazinthu monga mafoni am'manja, zovala ndi zida zamankhwala.

2. Kupititsa patsogolo ntchito: Magawo angapo mu PCB yamitundu yambiri amakhala ndi malo owonjezera kuti aphatikize zigawo zambiri ndi mabwalo ovuta.Izi zimathandizira kuphatikizika kwa zinthu zapamwamba monga mphamvu zopanda zingwe, machitidwe owongolera mphamvu, kutumiza mwachangu kwa data, ndi zina zambiri.Kupititsa patsogolo magwiridwe antchito operekedwa ndi ma PCB ambiri kumathandizira opanga kuti akwaniritse zomwe msika ukukula.

3. Kukhulupirika kwa chizindikiro ndi kuchepetsedwa kwa EMI: Pamene liwiro la deta likupitirirabe kuwonjezereka komanso kufalitsa chizindikiro chapamwamba kumafunika, ma PCB amitundu yambiri amapambana pa kuonetsetsa kuti chizindikirochi chikugwirizana ndi kuchepetsa kusokoneza kwa electromagnetic (EMI).Polekanitsa ndege zamphamvu ndi zapansi kuchokera ku ndege zowonetsera, matabwawa amachepetsa crosstalk ndikusunga kukhulupirika kwa zizindikiro zosakhwima.Izi zimawonjezera kusamutsa kwa data ndikuchepetsa mwayi wa zolakwika kapena kusokoneza.

4. Kudalirika kowonjezereka: Poyerekeza ndi PCB yosanjikiza imodzi kapena iwiri, PCB yamitundu yambiri imakhala yodalirika kwambiri.Kugawa ndi kuwongolera zigawo pamagulu angapo kumachepetsa chiopsezo cha kulephera kumodzi.Kuphatikiza apo, kupukutira pamabowo ndi ma vias kumawonjezera kapangidwe kake ndikupangitsa gululo kupirira kupsinjika kwamafuta ndi kugwedezeka, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pamagalimoto, mlengalenga ndi mafakitale.

5. Kusinthasintha kwapangidwe: Kusinthasintha kwa ma PCB amitundu yambiri kumathandizira okonza kuti agwiritse ntchito masanjidwe ovuta, kuphatikiza ma analogi ndi ma digito.Kusinthasintha uku kumapatsa mainjiniya ufulu wochulukirapo kuti apange zatsopano ndikuwongolera njira yopangira.Kuonjezera apo, kusintha kwa mapangidwe a dera ndi kusintha kungapangidwe popanda kukhudza dongosolo lonse la bolodi, kuchepetsa nthawi ya chitukuko ndi ndalama.

Pezani zosowa zamakono zamakono:

Kukula kwakukula kwa zida zazing'ono, zanzeru zamagetsi kumafuna kugwiritsa ntchito ma PCB amitundu yambiri.Kutha kwawo kutengera magwiridwe antchito ambiri, kupereka kukhulupirika kwachizindikiro, kuwongolera kudalirika komanso kupereka kusinthasintha kwamapangidwe kumawapangitsa kukhala chisankho chanzeru kwa opanga omwe akufuna kukhala patsogolo paukadaulo womwe ukupita patsogolo mwachangu.

Multilayer PCBs asintha makampani opanga zamagetsi popereka maubwino ambiri kuposa ma board achikhalidwe.Pomwe kufunikira kwa zida zamagetsi zophatikizika kwambiri, zophatikizika komanso zapamwamba zikupitilira kukwera, kufunikira kwa ma PCB amitundu yambiri kukuwonekera kwambiri.Povomereza ukadaulo uwu, opanga amatha kukwaniritsa zofuna za ogula pazinthu zatsopano pomwe akuwonetsetsa kudalirika, magwiridwe antchito komanso kukhutitsidwa kwamakasitomala.
