Mipikisano wosanjikiza PCB mawaya mkati ndi kunja pad malumikizidwe

Momwe mungasamalire bwino mikangano pakati pa mawaya amkati ndi maulumikizidwe akunja akunja pama board osindikizira amitundu yambiri?

M'dziko lamagetsi, mapepala osindikizira (PCBs) ndi njira yopulumutsira yomwe imagwirizanitsa zigawo zosiyanasiyana pamodzi, kulola kulankhulana kosasunthika ndi kugwira ntchito. Ma PCB a Multilayer, makamaka, akuchulukirachulukira kutchuka chifukwa cha magwiridwe antchito ake komanso kachulukidwe kagawo kakang'ono. Komabe, zovuta zawo zimapangitsa kuti pakhale vuto loyendetsa mikangano pakati pa mizere yamkati ndi malumikizano akunja a pad.Mu blog iyi, tiwona njira zabwino zothetsera kusamvanaku ndikuwonetsetsa kuti magwiridwe antchito ndi odalirika.

Multilayer PCB

1. Kumvetsetsa kusamvana:

Kuti muthetse bwino vuto lililonse, ndikofunikira kumvetsetsa chifukwa chake. Kusamvana pakati pa mizere yamkati ndi kugwirizana kwa mapepala akunja kumachitika chifukwa cha zofunikira zawo zosiyanasiyana. Kufufuza kwamkati kumafuna m'lifupi mwake ndi malo ocheperako podutsa kachulukidwe, pomwe mapepala akunja amafunikira makulidwe okulirapo kuti azitha kugulitsira zinthu ndi kulumikizana. Kusemphana pakati pa zofunikirazi kungayambitse mavuto osiyanasiyana, monga kutaya kukhulupirika kwa chizindikiro, kutulutsa kutentha kwakukulu, ngakhale akabudula amagetsi. Kuzindikira ndi kumvetsetsa kusamvanaku ndi sitepe yoyamba yopezera yankho.

2. Konzani mapangidwe:

Chinsinsi chothetsera mikangano chagona pakukonza mapangidwe a ma PCB amitundu yambiri. Izi zitha kutheka pogwiritsa ntchito njira izi:

- Kukonzekera mosamalitsa kokwanira:Kusanjikiza koganiziridwa bwino ndikofunikira pakulinganiza zosoweka zamkati ndi mapepala akunja. Kuyika zigawo zamkati zamkati pafupi ndi midplane ya PCB stackup kumapangitsa kuti pakhale kuwongolera komanso kukhulupirika kwazizindikiro. Kumbali inayi, kuyika mapepala akunja pamtunda wakunja kumapereka mwayi wopezeka ku gawolo.

- Njira zoyenera zopangira ma wiring:Gwiritsani ntchito njira zamawaya monga ma microvias ndi ma blinds kuti mulumikize mizere yamkati ndi mapepala akunja. M'mimba mwake yaying'ono ya microvia imapereka kachulukidwe kopitilira muyeso popanda kusokoneza mtundu wa chizindikiro. Akhungu vias kulumikiza zigawo zochepa moyandikana, kupereka kuda mkati njira yachindunji ziyangoyango kunja popanda kudutsa lonse PCB okwana.

- Zolinga zofananira ndi Impedans:Kusagwirizana pakati pa mizere yamkati ndi mapadi akunja kungayambitse kuwunikira komanso kutsika kwa magwiridwe antchito. Gwiritsirani ntchito njira zofananira zofananira monga kuwongolera kwa dielectric, kukhathamiritsa kutsata m'lifupi, ndi kuyimitsa koyenera kuti muwonetsetse kuti ma siginecha amagwirizana pa PCB yonse.

- Kuwongolera kwamafuta:Kuzizira kokwanira ndikofunikira kuti pakhale ntchito yodalirika ya PCB. Kupanga PCBs ndi vias matenthedwe kuti bwino kusamutsa kutentha kwaiye ndi zigawo ili pafupi ziyangoyango kunja kwa zigawo zamkati.

3. Mgwirizano ndi kulumikizana:

Kuwongolera mikangano pamapangidwe a PCB nthawi zambiri kumafuna mgwirizano pakati pa okhudzidwa osiyanasiyana, monga akatswiri opanga mapangidwe, opanga ma PCB, ndi akatswiri apagulu. Kusunga njira zoyankhulirana zogwira mtima ndikofunikira kuti aliyense amvetsetse zopinga ndi zofunikira. Misonkhano yanthawi zonse ndi zokambirana zingathandize kugwirizanitsa ziyembekezo ndi kuthetsa mikangano mwa kugawana mavuto.

4. Kuyerekezera ndi kusanthula:

Gwiritsani ntchito zida zoyezera ndi zowunikira kuti mutsimikizire momwe magetsi amapangidwira, kukhulupirika kwa ma siginecha, ndi mawonekedwe amafuta. Zida zimenezi zimapereka chidziwitso chokwanira cha khalidwe la PCB, kuthandizira kuzindikira mikangano yomwe ingakhalepo ndikukonzekera bwino musanapangidwe. Kuyerekezera kumathandizanso kukhathamiritsa kwa ma siginoloji ndikuwonetsetsa kufananiza kwa mizere yamkati ndi mapepala akunja.

5. Kujambula ndikuyesa:

Prototyping ndi kuyesa ndi njira zofunika kutsimikizira magwiridwe antchito ndikuthetsa mikangano yomwe yatsala. Poyang'anitsitsa PCB panthawi yoyesera, mainjiniya amatha kuzindikira madera omwe mikangano imapitilira ndikukonzanso mapangidwewo. Prototyping imaperekanso mwayi wotsimikizira njira zoyendetsera kutentha ndikuwonetsetsa kudalirika kwathunthu kwa PCB.

Powombetsa mkota

Kuwongolera kusamvana pakati pa kutsata kwamkati ndi kulumikizana kwa pad zakunja mu ma PCB ambiri kumafuna njira yokhazikika yomwe imaphatikiza machitidwe okonzekera bwino, kulumikizana bwino, zida zofananira ndi kusanthula, komanso kuyesa kokwanira. Pomvetsetsa zomwe zimayambitsa mikangano ndikugwiritsa ntchito njira zomwe tafotokozazi, mutha kukwaniritsa mapangidwe oyenera omwe amatsimikizira magwiridwe antchito, kudalirika, ndi magwiridwe antchito a PCB yanu yambiri.
