Gadzirisa HDI Flex PCB dhizaini uye zvinongedzo kuti uvandudze mhando yechiratidzo uye kuderedza kureba kwekutevera

suma:

Mune ino blog post, isu tichaongorora zvakakosha kufunga uye matekiniki ekutevera kudzikisa kureba uye pakupedzisira kugadzirisa HDI flex PCB chiratidzo chemhando.

High-density interconnect (HDI) flexible printed circuit boards (PCBs) isarudzo iri kuramba ichizivikanwa mumagetsi emazuva ano nekuda kwekubatana uye kuita zvakasiyana-siyana.Nekudaro, kugadzira uye kuita yakakwana chikamu chekuisa uye nzira dzekubatanidza dzeHDI inoshanduka PCB inogona kuve basa rakaoma.

Kukosha kwekuiswa kwechikamu uye nzira dzekubatanidza:

Kurongeka kwechikamu uye nzira dzekubatanidza dzine mhedzisiro yakakura pakuita kwese kweHDI flexible PCBs.Kunyatsokwenenzverwa kwechikamu chekuisa uye nzira dzekufambisa dzinogona kuwedzera kutendeseka kwechiratidzo uye kuderedza kukanganiswa kwechiratidzo.Nekudzikisa kureba kwemutsara, tinogona kuderedza kunonoka kwekutapurirana uye kurasikirwa kwechiratidzo, nekudaro tichivandudza kuvimbika kwehurongwa uye kuita.

Zvinhu zvekufunga nezvazvo pakusarudza chimiro chechikamu:

1. Signal flow analysis:

Usati watanga kuiswa kwechikamu, zvakakosha kuti unzwisise kuyerera kwechiratidzo uye kuona nzira yakakosha.Kuongorora nzira dzechiratidzo kunotibvumira kukwidziridza kuiswa kwezvikamu zvinokanganisa zvakanyanya kutendeseka kwechiratidzo.

2. Kuiswa kwepamusoro-kumhanya zvikamu:

High-speed components, senge microprocessors uye memory chips, zvinoda kunyatsotarisirwa.Kuisa zvinhu izvi padhuze kune mumwe nemumwe kunoderedza kunonoka kupararira kwechiratidzo uye kunoderedza kudiwa kwekutevera.Pamusoro pezvo, kuisa yakakwira-kumhanya zvikamu padyo nemagetsi kunobatsira kuderedza simba rekugovera network (PDN) impedance, kubatsira chiratidzo chekuvimbika.

3. Kubatanidzwa kwezvikamu zvinoenderana:

Kubatanidza zvinhu zvine chekuita nemapoka (zvakadai sedhijitari uye analogi zvikamu) muhurongwa kunodzivirira kupindira uye crosstalk.Inokurudzirwawo kuparadzanisa yakakwirira-yekumhanya yedhijitari uye analog masaini kudzivirira kubatana uye kukanganisa.

4. Decoupling capacitor:

Decoupling capacitors yakakosha kuchengetedza simba rakagadzikana kune akasanganiswa maseketi (ICs).Kuaisa padhuze nepazvinogoneka kune iyo IC's magetsi mapini kunoderedza inductance uye inowedzera kushanda kwemagetsi ekupa decoupling.

Zvinhu zvekucherechedza pakusarudza nzira yekubatanidza:

1. Kusiyana kwepairi nzira:

Mapaya akasiyana anowanzo shandiswa pakumhanyisa data data.Kufambiswa kwakakodzera kwemapeya akasiyana kwakakosha pakuchengetedza kuvimbika kwechiratidzo.Kuchengeta zviteshi zvakaenzana uye kuchengetedza nzvimbo inogara iripo pakati pematanho kunodzivirira chiratidzo skew uye inoderedza kukanganiswa kwemagetsi (EMI).

2. Impedance control:

Kuchengetedza inodzorwa impedance kwakakosha kune yakakwirira-kumhanya chiratidzo chekufambisa.Kushandisa inodzorwa impedance traces yeakakwira-kumhanya masaini anogona kudzikisa kutarisisa uye kukanganiswa kwechiratidzo.Kubatanidza impedance Calculator uye simulation maturusi mune dhizaini maitiro anogona kubatsira zvakanyanya mukuwana yakakwana impedance control.

3. Yakananga nzira:

Kuti uderedze kureba kwenzira, zvinokurudzirwa kusarudza nzira dzakatwasuka pese pazvinogoneka.Kuderedza nhamba vias uye kushandisa mapfupi trace kureba kunogona zvikuru kunatsiridza chiratidzo chiratidzo nokuderedza chiratidzo kurasikirwa.

4. Dzivisa kubhenda uye makona:

Bend uye makona mumutsara anounza imwe impedance uye kusaenderera kwechiratidzo, zvichikonzera kudzikisira kwechiratidzo.Kufambisa mumitsara yakatwasuka kana hombe-radius macurves kunobatsira kuderedza zviratidzo zvechiratidzo uye kuchengetedza chiratidzo chekuvimbika.

Zvibereko uye zvakanakira:

Nekutevera zvinotariswa pamusoro uye matekiniki, vagadziri vanogona kuwana yakagadziridzwa zvizere chikamu chekuisa uye nzira dzekubatanidza dzeHDI inoshanduka PCB.Unogona kuwana zvinotevera zvinobatsira:

1. Kuvandudza chiratidzo chemhando:

Kuderedza kureba kwemutsara kunoderedza kunonoka kutapurirana, kurasikirwa kwechiratidzo, uye kukanganiswa kwechiratidzo.Izvi zvinowedzera chiratidzo chemhando uye inovandudza mashandiro ehurongwa.

2. Deredza kupindirana uye kukanganisa:

Kubatana kwakakodzera kwechikamu uye kupatsanurwa kunogona kuderedza crosstalk uye kukanganisa, nekudaro kunatsiridza kutendeseka kwechiratidzo uye kuderedza ruzha rwehurongwa.

3. Kuvandudza EMI/EMC kuita:

Optimal cabling matekiniki uye impedance control inoderedza kukanganiswa kwemagetsi uye inovandudza kuenderana kwemagetsi eiyo system.

4. Kugovera simba kunoshanda:

Strategic kuiswa kwepamusoro-kumhanya zvikamu uye decoupling capacitors inovandudza simba rekugovera simba, zvichiwedzera kusimbisa chiratidzo chekuvimbika.

Mukupedzisa:

Kuti uvandudze mhando yechiratidzo uye kudzikisa kureba kwekutevera muHDI flex PCBs, vagadziri vanofanirwa kunyatso funga nezve chikamu marongero uye nzira dzekubatanidza.Kuongorora kuyerera kwechiratidzo, kunyatsoisa zvinhu zvinomhanya-mhanya, kushandisa decoupling capacitor, uye kushandisa nzira dzakagadziridzwa dzenzira dzinoita basa rakakosha mukuwana kuvimbika kwechiratidzo.Nekutevera nhungamiro idzi, vagadziri vemagetsi vanogona kuve nechokwadi chekuvandudzwa kwepamusoro-kuita uye yakavimbika HDI inoshanduka PCBs.
