Saizi uye zviyero zveceramic redunhu mabhodhi

Mune ino blog post, isu tichaongorora akajairwa saizi uye zviyero zveceramic redunhu mabhodhi.

Ceramic redunhu mabhodhi ari kuramba achizivikanwa muindasitiri yemagetsi nekuda kwehunhu hwavo hwepamusoro uye mashandiro achienzaniswa neachinyakare PCBs (Akadhindwa Circuit Boards). Iyo inozivikanwawo seceramic PCBs kana ceramic substrates, aya mabhodhi anopa yakanakisa yekupisa manejimendi, yakakwira mechini simba uye kuita kwakanaka kwemagetsi.

1. Mhedziso yemapuranga edunhu receramic:

Ceramic circuit boards inogadzirwa neceramic zvinhu zvakaita sealuminium oxide (Al2O3) kana silicon nitride (Si3N4) pachinzvimbo cheyakajairwa FR4 zvinhu zvinoshandiswa mutsika PCBs. Ceramic zvinhu zvine zviri nani thermal conductivity uye zvinogona kunyatso bvisa kupisa kubva kune zvikamu zvakaiswa pabhodhi. Ceramic PCBs anoshandiswa zvakanyanya mumashandisirwo anoda simba repamusoro uye masaini akakwirira, akadai semagetsi emagetsi, mwenje we LED, aerospace uye kufonera.

2. Zviyero uye zviyero zveceramic circuit board:

Ceramic redunhu bhodhi saizi uye zviyero zvinogona kusiyana zvichienderana nechaiyo mashandisirwo uye dhizaini zvinodiwa. Nekudaro, kune mamwe akajairwa saizi uye zviyero izvo zvinowanzoshandiswa muindasitiri. Ngatinyure muzvikamu izvi:

2.1 Hurefu, upamhi uye ukobvu:
Ceramic circuit boards inouya muhurefu hwakasiyana, hupamhi uye makobvu kuti aenderane nemagadzirirwo akasiyana uye mashandisirwo. Hurefu hwakajairika hunobva pamamirimita mashoma kusvika pamazana akati wandei, nepo hupamhi hunogona kusiyana kubva pamamirimita mashoma kusvika pa250 millimita. Kana iri ukobvu, inowanzoita 0.25 mm kusvika 1.5 mm. Nekudaro, saizi iyi inogona kugadzirwa kuti isangane nezvinodiwa zveprojekiti.

2.2 Nhamba yezvikamu:
Nhamba yezvikamu muceramic circuit board inosarudza kuoma kwayo uye kushanda kwayo. Ceramic PCBs inogona kuve neakawanda akaturikidzana, anowanzo kubva kune imwechete kusvika matanhatu-layer dhizaini. Mamwe mapeji anobvumira kubatanidzwa kwezvimwe zvikamu uye zvinyorwa, izvo zvinoita kuti zvive nepamusoro-density circuit designs.

2.3 Hukuru hwegomba:
Ceramic PCBs inotsigira akasiyana aperture saizi zvichienderana nezvinodiwa zvekushandisa. Makomba anogona kupatsanurwa mumhando mbiri: akaputirwa nemakomba (PTH) uye asina-akaputirwa nemakomba (NPTH). Yakajairika PTH hole saizi inotangira pa 0.25 mm (10 mils) kusvika 1.0 mm (40 mils), nepo NPTH gomba saizi inogona kuita diki se0.15 mm (6 mils).

2.4 Tsanangudzo uye nzvimbo yakafara:
Kuteedzera uye nzvimbo yakafara mumapurani eceramic edunhu anoita basa rakakosha mukuona kwakaringana chiratidzo chekuvimbika uye kushanda kwemagetsi. Yakajairika trace widths inotangira pa 0.10 mm (4 mils) kusvika 0.25 mm (10 mils) uye inosiyana zvichienderana nekugona kutakura ikozvino. Saizvozvo, gap hupamhi hunosiyana pakati pe 0.10 mm (4 ms) uye 0.25 mm (10 mils).

3. Zvakanakira zveceramic redunhu mabhodhi:

Izvo zvakakosha kuti unzwisise akajairwa saizi uye zviyero zveceramic dunhu mabhodhi, asi zvakakosha zvakaenzana kuti unzwisise zvakanakira zvavanopa:

3.1 Thermal manejimendi:
Iyo yakakwira yekupisa conductivity yezvinhu zveceramic inova nechokwadi chekupisa kupisa kwezvikamu zvesimba, nekudaro zvichiwedzera kuvimbika kwehurongwa hwese.

3.2 Mechanical simba:
Ceramic redunhu mabhodhi ane yakanakisa mechani simba, ichiita kuti irambe yakasimba kune akasiyana ekunze zvinhu senge vibration, kuvhunduka uye mamiriro ekunze.

3.3 Kuita kwemagetsi:
Ceramic PCBs ine yakaderera dielectric kurasikirwa uye yakaderera chiratidzo kurasikirwa, ichigonesa yakakwira-frequency kushanda uye kuvandudza chiratidzo chekuvimbika.

3.4 Miniaturization uye yakakwirira-density dhizaini:
Nekuda kwehukuru hwavo hudiki uye zvirinani kupisa zvivakwa, ceramic dhizaini mabhodhi anogonesa miniaturization uye yakakwirira-density dhizaini uku ichichengetedza yakanakisa kushanda kwemagetsi.

4. mukupedzisa:

Saizi yakajairika uye zviyero zveceramic redunhu mabhodhi zvinosiyana zvichienderana nekushandiswa uye dhizaini zvinodiwa. Kureba kwavo uye hupamhi hunobva pamamirimita mashoma kusvika kumazana emazana emamirimita, uye ukobvu hwavo hunobva pa 0.25 mm kusvika 1.5 mm. Huwandu hwematanho, saizi yegomba, uye hupamhi hwekutsvagisa zvakare inoita basa rakakosha pakuona kushanda nekuita kweceramic PCBs. Kunzwisisa zviyero izvi kwakakosha pakugadzira nekushandisa masisitimu emagetsi anoshanda anotora mukana weceramic circuit board.
