Mitundu yosiyanasiyana ya mapangidwe a board a ceramic

Mu positi iyi ya blog, tiwona mitundu yosiyanasiyana ya mapangidwe a board a ceramic ndi mawonekedwe ake apadera.

Ma board a Ceramic akuchulukirachulukira kutchuka chifukwa chaubwino wawo wambiri kuposa zida zama board board monga FR4 kapena polyimide. Ma board a Ceramic akukhala chisankho choyamba pazogwiritsa ntchito zosiyanasiyana chifukwa cha matenthedwe abwino kwambiri, kukana kutentha kwambiri komanso mphamvu zamakina. Kufuna kukuchulukirachulukira, momwemonso mitundu yosiyanasiyana yama board a ceramic omwe amapezeka pamsika.

1. Alumina-based ceramic ceramic circuit board:

Aluminium oxide, yomwe imadziwikanso kuti aluminium oxide, ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri pama board a ceramic circuit. Ili ndi zida zabwino kwambiri zotchinjiriza magetsi ndipo ndiyoyenera kugwiritsa ntchito zomwe zimafunikira mphamvu ya dielectric yayikulu. Ma board ozungulira a alumina ceramic amatha kupirira kutentha kwambiri, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito pamagetsi apamwamba kwambiri monga magetsi amagetsi ndi makina amagalimoto. Kumapeto kwake kosalala komanso kocheperako komwe kumawonjezera kutentha kumapangitsa kuti ikhale yabwino pamagwiritsidwe okhudzana ndi kasamalidwe ka kutentha.

2. Aluminiyamu nitride (AlN) ceramic dera bolodi:

Ma aluminium nitride ceramic circuit board ali ndi matenthedwe apamwamba kwambiri poyerekeza ndi magawo a aluminiyamu. Amagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe amafunikira kutentha koyenera, monga kuyatsa kwa LED, ma module amagetsi, ndi zida za RF/microwave. Aluminium nitride circuit board amapambana kwambiri pama frequency apamwamba chifukwa cha kuchepa kwawo kwa dielectric komanso kukhulupirika kwazizindikiro. Kuphatikiza apo, ma board ozungulira a AlN ndi opepuka komanso okonda zachilengedwe, zomwe zimawapangitsa kukhala oyenera m'mafakitale osiyanasiyana.

3. Silicon nitride (Si3N4) ceramic dera bolodi:

Ma board ozungulira a silicon nitride ceramic amadziwika chifukwa champhamvu zawo zamakina komanso kukana kugwedezeka kwamafuta. Ma mapanelowa nthawi zambiri amagwiritsidwa ntchito m'malo ovuta momwe kutentha kumasinthira, kupanikizika kwambiri, komanso zinthu zowononga. Ma board ozungulira a Si3N4 amapeza ntchito m'mafakitale monga mlengalenga, chitetezo, mafuta ndi gasi, komwe kudalirika ndi kulimba ndikofunikira. Kuphatikiza apo, silicon nitride ili ndi zida zabwino zotchingira magetsi, zomwe zimapangitsa kukhala chisankho chabwino kwambiri pakugwiritsa ntchito mphamvu zambiri.

4. LTCC (kutsika kutentha kowotchedwa ceramic) board board:

Ma board ozungulira a LTCC amapangidwa pogwiritsa ntchito matepi a ceramic multilayer omwe amasindikizidwa ndi ma conductive. Zigawozo zimayikidwamo ndikuwotchedwa pa kutentha kochepa, kupanga gulu lozungulira kwambiri komanso lodalirika. Tekinoloje ya LTCC imalola kuti zinthu zopanda pake monga resistors, capacitors ndi inductors ziphatikizidwe mkati mwa bolodi lokhalokha, zomwe zimapangitsa kuti miniaturization igwire bwino ntchito. Ma board awa ndi oyenera kulumikizana ndi ma waya, zamagetsi zamagalimoto, ndi zida zamankhwala.

5. HTCC (kutentha kwakukulu kowotchedwa ceramic) board board:

Ma board ozungulira a HTCC ndi ofanana ndi ma board a LTCC potengera kupanga. Komabe, matabwa a HTCC amawotchedwa pa kutentha kwakukulu, zomwe zimapangitsa kuti makina azigwira ntchito komanso kutentha kwambiri. Ma matabwawa amagwiritsidwa ntchito kwambiri pazida zotentha kwambiri monga masensa agalimoto, zamagetsi zammlengalenga, ndi zida zoboola pansi. Ma board ozungulira a HTCC ali ndi kukhazikika kwamatenthedwe ndipo amatha kupirira kutentha kwambiri kwa njinga.

Powombetsa mkota

Mitundu yosiyanasiyana ya matabwa a ceramic amapangidwa kuti akwaniritse zosowa zamakampani osiyanasiyana. Kaya ndikugwiritsa ntchito mphamvu zambiri, kutentha kwachangu, kutenthetsa kwachilengedwe kapena zofunikira za miniaturization, mapangidwe a board a ceramic amatha kukwaniritsa izi. Pomwe ukadaulo ukupitilira kupita patsogolo, ma board ozungulira a ceramic akuyembekezeka kutenga gawo lofunikira pakupangitsa kuti zida zamagetsi zodalirika zitheke m'mafakitale onse.
