6-Layer PCB Dhizaini uye Zvishandiso

Munyika yemagetsi iri kukurumidza, uko zvishandiso zviri kuita zvidiki, nekukurumidza, uye zvine simba, mabhodhi ekudhinda e multilayer Printed Circuit Boards ( ma PCB ) ndiwo musimboti wekugadzirwa kwemazuva ano. Kunyange zvazvo ma PCB ane layer 4 akakwana kune akawanda mashandisirwo, kuwedzera kwekuda kwesimba rakawanda, kumhanya kwesignali nekukurumidza, uye huwandu hwakawanda hwezvikamu zvinowanzoda kuvandudzwa kuenda kuma PCB ane layer 6. Chinyorwa chino chinotarisa zvakadzama mabhenefiti, pfungwa dzekugadzira, uye mashandisirwo epamusoro ema PCB ane layer 6, zvichipa ruzivo rwakakosha kune mainjiniya nevagadziri zvakafanana.

Sei Sarudza 6-Layer PCB?

PCB ine mativi matanhatu inopa mhinduro yepamusoro kupfuura PCB ine mativi mana, ichipa mamwe mativi ekufambisa anogonesa kuvandudzwa kwechiratidzo, kugoverwa kwesimba, uye Electromagnetic Compatibility ( EMC ). Matanda ekuwedzera akakosha kune zvishandiso zvine ma interfaces ekumhanya kwepamusoro kana izvo zvinoshanda munzvimbo umo kuderedza ruzha nekupindira kwakakosha.

Heano mabhenefiti akakosha e6-layer PCBs:

• Kuwedzeredza Chiratidzo Kutendeseka: Nendege dzepasi dzakatsaurirwa dzakaiswa padhuze nezvikamu zvechiratidzo, 6-layer PCB inoderedza ruzha uye crosstalk, kuve nechokwadi kuti masaini ekumhanya-mhanya anochengetedza kuvimbika kwavo.
• Kufambiswa Kwemagetsi kwakavandudzwa: Nekubatanidza simba rakasiyana uye ndege dzepasi, 6-layer PCBs inogovera simba zvakanyanya, kuderedza kushanduka kwemagetsi uye kuve nechokwadi chekuita kwakagadzikana.
• Zvirinani EMI Kudzora: Kuiswa kwehungwaru kwepasi uye ndege dzemagetsi dzinoita senhoo kurwisa kukanganiswa kwemagetsi (Ichimura), kuve nechokwadi chekuti masaini anoramba akachena uye asina kusvibiswa.
• Higher Routing Capacity: Iwo maturu ekuwedzera anopa imwe nzvimbo yekufambisa, zvichiita kuti zvikwanise kugadzira masekete akaomarara ane akakwira chikamu densities pasina kukanganisa kushanda.

6-Layer PCB Stackup: Dhizaina Maitiro Akanakisisa

Paunenge uchigadzira 6-layer PCB, iyo stackup (kurongeka kwezvikamu) inoita basa rakakosha pakuona mashandiro ebhodhi. Iyo yakanyatso kurongwa stackup inoderedza kuratidzwa kwechiratidzo, inova nechokwadi chekuti impedance, uye inobatsira mukudzikisa kukanganiswa kwemagetsi.

Yakakwana 6-Layer PCB Stackup

Iyo yakajairika 6-layer PCB stackup ine inochinjana chiratidzo uye ndege zvidimbu. Yakajairika stackup inoita seizvi:

• Layer 1 (Pamusoro Chiratidzo): Inoshandiswa kune yakakwirira-kumhanya chiratidzo chekufambisa.
• Layer 2 (Ndege Yepasi): Inopa chirevo chekudzoka kwechiratidzo uye EMI kudzivirira.
• Layer 3 (Chiratidzo chemukati 1): Yakachengeterwa kufambisa masaini epamusoro-frequency.
• Layer 4 (Chiratidzo chemukati 2): Inowanzo shandiswa kufambisa magetsi njanji kana mamwe masaini.
• Layer 5 (Ndege Yemagetsi): Inopa simba kune zvikamu uchichengetedza yakaderera impedance.
• Layer 6 (Pazasi Chiratidzo): Inoshandiswa kune yakaderera-kumhanya chiratidzo routing uye kunze kwekubatanidza.

Iyi gadziriso inopa yakanakisa chiratidzo kutendeseka, ine masaini anofambiswa pakati pepasi uye simba ndege, kuderedza njodzi yeruzha uye kupindira. Kushandiswa kweakatetepa dielectrics pakati pemasignal layers anovandudza impedance control, ichiita iyi stackup yakanakira maseketi ekumhanya.

Makiyi Dhizaini Mazano e6-Layer PCBs

1. Shandisa Yakatsaurirwa Ground Planes: Ndege dzepasi dzinofanirwa kuiswa padivi pemasaini akaturikidzana kuderedza ruzha rwepasi uye kugadzirisa nzira dzekudzoka kwechiratidzo.
2. Kudzora Impedance: Kune zvikwangwani zvekumhanya zvakanyanya, zvakakosha kuti uchengetedze kusagadzikana nekunyatso dhizaini yekutevera upamhi uye nzvimbo.
3. Shield High-Speed ​​Signals: Isa zvikwangwani zvekumhanya-mhanya pakati pendege dzepasi kudzivirira EMI uye crosstalk.
4. Optimize Simba uye Ground Layer Kuiswa: Masimba uye pasi pasi anofanira kunge ari pedyo pamwe chete kuderedza loop inductance, kuderedza EMI uye kuve nechokwadi chekugadzika kwemagetsi kugovera.
5. Symmetry ndiyo Kiyi: Chengetedza symmetrical stackup kudzivirira warping panguva yekugadzira uye kusangana.

Kubata Ball Grid Arrays (BGAs) mu6-Layer PCBs

Paunenge uchishandisa Ball Grid Array (BGA) zvinoumba 6-layer PCBs, kungwarira routing kunodiwa kudzivisa kupatsanura pasi ndege ane vias akawandisa.
