Kubata Yakakwira-Kumhanya Digital Signals HDI PCB Prototyping

suma:

Tikugashirei kuCapel's blog, uko chinangwa chedu ndechekupa gwara rakazara rekuita prototyping HDI PCBs uchishandisa yakakwirira-kumhanya masaini edhijitari. Nemakore gumi nemashanu eruzivo rwekugadzira bhodhi redunhu, timu yedu yakazvitsaurira yenyanzvi inogona kukubatsira kufamba kuomarara kweprototyping nekugadzira. Isu tinopa pre-kutengesa uye mushure-kutengesa tekinoroji masevhisi kuti tive nechokwadi chekugutsikana kwevatengi.Muchinyorwa chino, tichaongorora kuomarara kweHDI PCB prototyping, kuratidza kukosha kweyepamusoro-kumhanya masaini edhijitari, uye nekupa ruzivo rwakakosha kukubatsira iwe kukunda mumunda.

Chikamu 1: Kunzwisisa Zvinorehwa neHDI PCB Prototyping

Kuti uwane kuita kwakaringana uye kushanda, zvakakosha kuti unzwisise kukosha kweHDI PCB prototyping mune yakakwirira-kumhanya yedhijitari application. High-density interconnect (HDI) PCBs akagadzirwa kuti agare akawanda akaturikidzana uye akaomarara wedunhu, nekudaro achiwedzera kutendeseka kwechiratidzo, kuderedza kupindira, nekuvandudza kushanda kwemagetsi. Izvi zvivakwa zvinowedzera kukosha kana uchigadzira yakakwirira-kumhanya masaini edhijitari, uko kunyangwe diki impedance mismatches kana kusarongeka kwechiratidzo kunogona kutungamira kuhuori kana kurasikirwa kwedata.

Chikamu 2: Mafungiro Akakosha ePrototyping HDI PCBs

2.1 Dhizaini Yekugadzira (DfM)
Dhizaini Yekugadzira (DfM) inoita basa rakakosha muHDI PCB prototyping. Kushanda padhuze nevagadziri vebhodhi panguva yekutanga yekufunga kwechikamu kunobvumira kusanganisa kusina musono kwemaitiro ekugadzira uye kugona kugadzira. Nekubatanidza misimboti yeDfM senge kukwenenzvera upamhi, kusarudza zvinhu zvakakodzera, uye kufunga nezvekuiswa kwechikamu, unogona kudzikisira zvinogona kunetsa kugadzira uye kuderedza mitengo yese.

2.2 Kusarudzwa kwezvinhu
Kusarudza zvinhu zvakakodzera zveHDI PCB prototypes kwakakosha kuti uwane yakakwana yemagetsi kuita uye kuvimbika. Zvishandiso zvine yakaderera dielectric inogara, inodzorwa impedance zvivakwa, uye yakanakisa chiratidzo chekuparadzira hunhu zvinofanirwa kutsvakwa. Pamusoro pezvo, funga kushandisa akasarudzika akakwira-kumhanya laminates kudzora zvakasimba kutendeseka kwechiratidzo uye kuderedza kurasikirwa kwechiratidzo.

2.3 Stackup dhizaini uye chiratidzo chekuvimbika
Yakakodzera stackup dhizaini inogona kukanganisa zvakanyanya chiratidzo chekuvimbika uye kuita kwese. Layer kuiswa, ukobvu hwemhangura, uye dielectric ukobvu hunofanirwa kurongeka nekuchenjera kuderedza crosstalk, kurasikirwa kwechiratidzo, uye kukanganiswa kwemagetsi. Kushandisa inodzorwa impedance routing tekinoroji uchiomerera kune indasitiri zviyero zvinobatsira kuchengetedza chiratidzo chekuvimbika uye kuderedza kuratidzwa.

Chikamu 3: HDI PCB Prototyping Technology

3.1 Microhole laser drilling
Microvias yakakosha pakuwana yakakwira-density wedunhu muHDI PCB uye inogona kugadzirwa nemazvo uchishandisa laser drilling tekinoroji. Laser drilling inogonesa kudzora kwakaringana kuburikidza nehukuru, aspect ratio uye pad size, kuve nechokwadi chekubatana kwakavimbika kunyangwe mudiki fomu zvinhu. Kushanda nemugadziri wePCB ane ruzivo seCapel kunovimbisa kunyatsoitwa kweiyo yakaoma maitiro ekuchera laser.
3.2 Sequential lamination
Sequential lamination ndiyo yakakosha tekinoroji inoshandiswa muHDI PCB prototyping process uye inosanganisira laminating akawanda akaturikidzana pamwechete. Izvi zvinobvumira nzira yakasimba, kureba kwekubatanidza, uye kuderedzwa kweparasitics. Nekushandisa tekinoroji yekuvandudza tekinoroji senge Build-Up process (BUP), unogona kuwana yakakwira densities pasina kukanganisa kutendeseka kwechiratidzo.

Chikamu 4: Maitiro Akanakisa ePamusoro-Speed ​​Digital Signal Kutendeseka

4.1 Impedance control uye chiratidzo chekuvimbika kuongororwa
Kuita maitiro ekudzora impedance senge inodzorwa impedance traces uye impedance kuenzanisa kwakakosha kuchengetedza chiratidzo chekutendeseka mune yakakwirira-kumhanya dhizaini dhizaini. Yepamberi yekunyepedzera maturusi anogona kukubatsira kuongorora chiratidzo chekutendeseka nyaya, kuona zvinogona kuchinja impedance, uye kukwidziridza PCB dhizaini zvinoenderana.

4.2 Chiratidzo cheKutendeseka Dhizaini Mirayiridzo
Kutevera indasitiri-yakajairwa dhizaini nhungamiro yeakakwira-kumhanya masaini edhijitari anogona kusimudzira kuita kwese kweHDI PCB prototype yako. Mamwe maitiro ekuchengeta mupfungwa ari kuderedza discontinuities, optimizing kudzoka nzira, uye kuderedza nhamba vias munzvimbo yakakwirira-kumhanya. Kushanda nechikwata chedu chine ruzivo rwehunyanzvi hwekutsvagisa nekusimudzira kunogona kukubatsira kutevedzera izvi zvinongedzo.

Mukupedzisa:

Prototyping HDI PCBs uchishandisa yakakwirira-kumhanya masaini edhijitari inoda kutarisisa kune zvakadzama.Nekusimudzira hunyanzvi hweCapel uye ruzivo, unogona kugadzirisa maitiro, kuderedza njodzi dzekugadzira uye kuwana mhedzisiro yepamusoro. Kunyangwe iwe uchida kukurumidza prototyping kana vhoriyamu kugadzirwa, yedu yedunhu bhodhi kugadzira zvivakwa zvinogona kuzadzisa zvaunoda. Bata timu yedu yehunyanzvi nhasi kuti uwane mukwikwidzi munyika inokurumidza-yepamusoro yedhijitari chiratidzo chedhijitari HDI PCB kugadzira.
