Kukula ndi makulidwe a matabwa ozungulira a ceramic

Mu positi iyi yabulogu, tiwona kukula kwake ndi makulidwe a matabwa a ceramic.

Ma board a Ceramic akuchulukirachulukira m'makampani opanga zamagetsi chifukwa cha mawonekedwe awo apamwamba komanso magwiridwe antchito poyerekeza ndi ma PCB achikhalidwe (Mabodi Osindikizidwa Ozungulira). Amadziwikanso kuti ma PCB a ceramic kapena ma ceramic substrates, ma board awa amapereka kasamalidwe kabwino ka matenthedwe, mphamvu zamakina apamwamba komanso magwiridwe antchito abwino kwambiri amagetsi.

1. Chidule cha matabwa a ceramic:

Ma board a Ceramic amapangidwa ndi zida za ceramic monga aluminium oxide (Al2O3) kapena silicon nitride (Si3N4) m'malo mwazinthu zanthawi zonse za FR4 zomwe zimagwiritsidwa ntchito pama PCB achikhalidwe. Zida za Ceramic zimakhala ndi matenthedwe abwino kwambiri ndipo zimatha kutaya kutentha kuchokera kuzinthu zomwe zimayikidwa pa bolodi. Ma PCB a Ceramic amagwiritsidwa ntchito kwambiri pamapulogalamu omwe amafunikira mphamvu zambiri komanso ma siginoloji apamwamba kwambiri, monga zamagetsi zamagetsi, kuyatsa kwa LED, zakuthambo ndi matelefoni.

2. Makulidwe ndi makulidwe a matabwa a ceramic:

Ceramic circuit board makulidwe ndi makulidwe amatha kusiyanasiyana kutengera ntchito ndi kapangidwe kake. Komabe, palinso miyeso ndi miyeso yomwe imagwiritsidwa ntchito kwambiri m'makampani. Tiyeni tilowe m'mbali izi:

2.1 Utali, m'lifupi ndi makulidwe:
Ma board a Ceramic amabwera muutali, m'lifupi ndi makulidwe osiyanasiyana kuti agwirizane ndi mapangidwe ndi ntchito zosiyanasiyana. Utali wofananira umachokera ku mamilimita angapo mpaka mazana angapo mamilimita, pomwe m'lifupi mwake kumatha kusiyana ndi mamilimita angapo mpaka pafupifupi 250 mamilimita. Ponena za makulidwe, nthawi zambiri ndi 0.25 mm mpaka 1.5 mm. Komabe, makulidwe awa amatha kusinthidwa kuti akwaniritse zosowa za polojekiti.

2.2 Chiwerengero cha zigawo:
Kuchuluka kwa zigawo mu bolodi la dera la ceramic kumatsimikizira zovuta zake ndi magwiridwe antchito. Ma PCB a Ceramic amatha kukhala ndi zigawo zingapo, zomwe zimayambira pamitundu imodzi mpaka isanu ndi umodzi. Zigawo zambiri zimalola kuphatikizika kwa zigawo zowonjezera ndi zotsatizana, zomwe zimathandizira mapangidwe apamwamba a dera.

2.3 Kukula kwa dzenje:
Ma PCB a Ceramic amathandizira kukula kwake kosiyanasiyana kutengera zomwe mukufuna. Mabowo amatha kugawidwa m'magulu awiri: opangidwa ndi mabowo (PTH) ndi osakutidwa ndi mabowo (NPTH). Kukula kwake kwa dzenje la PTH kumachokera ku 0.25 mm (10 mils) mpaka 1.0 mm (40 mils), pomwe kukula kwa dzenje la NPTH kumatha kukhala kocheperako ngati 0.15 mm (6 mils).

2.4 Kutsata ndi kutalika kwa danga:
Kutsata ndi kukula kwa danga m'mabwalo ozungulira a ceramic kumagwira ntchito yofunika kwambiri pakuwonetsetsa kuti ma siginecha akuyenda bwino komanso magwiridwe antchito amagetsi. M'lifupi mwake amayambira 0.10 mm (4 mils) mpaka 0.25 mm (10 mils) ndipo amasiyana malinga ndi momwe amanyamulira. Momwemonso, kusiyana kwapakati kumasiyana pakati pa 0.10 mm (4 mils) ndi 0.25 mm (10 mls).

3. Ubwino wa matabwa a ceramic:

Ndikofunikira kumvetsetsa kukula kwake ndi makulidwe a matabwa a ceramic, koma ndikofunikiranso kumvetsetsa zabwino zomwe amapereka:

3.1 Kuwongolera kutentha:
Kutentha kwapamwamba kwazinthu za ceramic kumatsimikizira kutentha kwamphamvu kwa zigawo za mphamvu, motero kumawonjezera kudalirika kwa dongosolo lonse.

3.2 Mphamvu zamakina:
Ma matabwa a Ceramic ali ndi mphamvu zamakina abwino kwambiri, zomwe zimawapangitsa kukhala osagwirizana kwambiri ndi zinthu zosiyanasiyana zakunja monga kugwedezeka, kugwedezeka komanso chilengedwe.

3.3 Mphamvu zamagetsi:
Ma PCB a Ceramic ali ndi kutayika kwa dielectric pang'ono komanso kutayika kwa ma siginecha otsika, zomwe zimathandizira magwiridwe antchito apamwamba komanso kuwongolera kukhulupirika kwa ma sign.

3.4 Miniaturization ndi mapangidwe apamwamba kwambiri:
Chifukwa cha kukula kwawo kochepa komanso kutentha kwabwinoko, ma board a ceramic amathandizira kuti pakhale mawonekedwe ang'onoang'ono komanso osasunthika kwambiri pomwe akugwira ntchito bwino kwambiri zamagetsi.

4. Pomaliza:

Kukula kwake ndi makulidwe a matabwa a ceramic amasiyana malinga ndi kagwiritsidwe ntchito ndi kapangidwe kake. Kutalika kwawo ndi m'lifupi zimayambira mamilimita angapo mpaka mazana angapo millimeters, ndi makulidwe awo ranges kuchokera 0,25 mm kwa 1.5 mm. Kuchuluka kwa zigawo, kukula kwa dzenje, ndi m'lifupi mwake zimagwiranso ntchito pozindikira magwiridwe antchito ndi magwiridwe antchito a ceramic PCBs. Kumvetsetsa miyeso iyi ndikofunikira pakupanga ndi kukhazikitsa njira zamagetsi zamagetsi zomwe zimatengera mwayi pama board a ceramic.
