1. Kuki ukoresha ibibaho byumuzunguruko
Ubusanzwe PCB isanzwe ikozwe mu muringa no guhuza substrate, kandi ibikoresho bya substrate ahanini ni fibre yibirahure (FR-4), resin fenolike (FR-3) nibindi bikoresho, ibifatika mubisanzwe ni fenolike, epoxy, nibindi. Gutunganya PCB kubera guhangayikishwa nubushyuhe, ibintu bya shimi, inzira yumusaruro udakwiye nizindi mpamvu, cyangwa mugushushanya bitewe nimpande zombi za asimmetrie yumuringa, biroroshye kuganisha mubyiciro bitandukanye byo kurwanira PCB
PCB Twist
Ubundi PCB substrate - ceramic substrate, kubera imikorere yo gukwirakwiza ubushyuhe, ubushobozi bwo gutwara ibintu, insulasiyo, coefficente yo kwagura amashyuza, nibindi, nibyiza cyane kurenza ikibaho gisanzwe cya fibre fibre PCB, kubwibyo ikoreshwa cyane mumashanyarazi akomeye cyane. , ikirere, ibikoresho bya elegitoroniki nibindi bicuruzwa.
Ceramic substrates
Hamwe na PCB isanzwe ukoresheje ifiriti yumuringa hamwe na substrate guhuza, ceramic PCB iri mubushyuhe bwo hejuru, binyuze muburyo bwo guhuza umuringa wumuringa hamwe na ceramic substrate yacometse hamwe, imbaraga zikomeye zo guhuza, umuringa wumuringa ntuzagwa, kwizerwa cyane, imikorere ihamye murwego rwo hejuru ubushyuhe, ibidukikije byinshi
2. Ibikoresho byingenzi bya ceramic substrate
Alumina (Al2O3)
Alumina nigikoresho gikoreshwa cyane muri substrate ceramic, kubera ko mubukanishi, ubushyuhe nubushyuhe bwamashanyarazi ugereranije nibindi byinshi bya ceramique ya okiside, imbaraga nyinshi hamwe n’imiti ihamye, hamwe nisoko ryinshi ryibikoresho fatizo, bikwiranye nuburyo butandukanye bwo gukora ikoranabuhanga nuburyo butandukanye. .Ukurikije ijanisha rya alumina (Al2O3) irashobora kugabanywamo ibice 75, farashi 96, farashi 99.5.Ibikoresho byamashanyarazi ya alumina hafi ya byose ntabwo bigira ingaruka kubintu bitandukanye bya alumina, ariko imiterere yubukanishi hamwe nubushyuhe bwumuriro burahinduka cyane.Substrate ifite isuku nke ifite ibirahuri byinshi nubuso bunini.Iyo hejuru yubuziranenge bwa substrate, niko byoroha, byoroshye, igihombo giciriritse kiri hasi, ariko igiciro nacyo kiri hejuru
Okiside ya Beriliyumu (BeO)
Ifite ubushyuhe burenze ubw'icyuma cya aluminiyumu, kandi ikoreshwa mu bihe bikenewe ubushyuhe bwinshi.Iragabanuka vuba nyuma yubushyuhe burenze 300 but, ariko iterambere ryayo rigarukira kuburozi bwayo.
Nitride ya aluminium (AlN)
Ububiko bwa aluminium nitride nubutaka hamwe nifu ya aluminium nitride nkicyiciro nyamukuru cya kristalline.Ugereranije na alumina ceramic substrate, irwanya insulasiyo, izirinda kwihanganira imbaraga nyinshi, dielectric ihoraho.Ubushyuhe bwumuriro bwikubye inshuro 7 ~ 10 ubwa Al2O3, kandi coefficente yo kwagura amashyuza (CTE) igereranijwe hafi na chip ya silicon, ifite akamaro kanini kumashanyarazi akomeye.Mubikorwa byo kubyaza umusaruro, ubushyuhe bwumuriro wa AlN bugira ingaruka cyane kubirimo imyanda ya ogisijeni isigaye, kandi ubushyuhe bwumuriro burashobora kwiyongera cyane mukugabanya ibirimo ogisijeni.Kugeza ubu, ubushyuhe bwumuriro bwibikorwa
Ukurikije impamvu zavuzwe haruguru, birashobora kumenyekana ko ceramics ya alumina iri mumwanya wambere mubijyanye na micrélectronics, electronics electronique, microelectronics ivanze hamwe na modul yingufu bitewe nibikorwa byabo byiza byuzuye.
Ugereranije nisoko ryubunini bumwe (100mm × 100mm × 1mm), ibikoresho bitandukanye byigiciro cya ceramic substrate: 96% alumina 9.5 yuan, 99% alumina 18 yuan, nitride ya aluminium 150, 150, okiside ya beryllium 650 ikinyuranyo cyibiciro hagati yuburyo butandukanye nabwo ni bunini
3. Ibyiza nibibi bya ceramic PCB
Ibyiza
- Ubushobozi bunini bwo gutwara, 100A ubudahwema binyuze muri 1mm 0.3mm yumuringa wumuringa, ubushyuhe bwazamutse hafi 17 ℃
- Ubushyuhe bwiyongera ni 5 ℃ gusa iyo 100A ikomeza guca muri 2mm 0.3mm yumubiri wumuringa.
- Ibyiza byo gukwirakwiza ubushyuhe bwiza, coefficente yo kwagura ubushyuhe buke, imiterere ihamye, ntabwo byoroshye kurwara.
- Gukingira neza, kurwanya voltage nyinshi, kugirango umutekano wibikoresho byawe.
Ibibi
Gucika intege nimwe mubibi byingenzi, biganisha ku gukora imbaho nto gusa.
Igiciro kirazimvye, ibisabwa mubicuruzwa bya elegitoronike amategeko menshi kandi menshi, ikibaho cyumuzunguruko ceramic cyangwa gikoreshwa muri bimwe mubicuruzwa byo mu rwego rwo hejuru, ibicuruzwa byo hasi ntibizakoreshwa na gato.
4. Ikoreshwa rya ceramic PCB
a.Imbaraga zikomeye za elegitoronike, module yizuba, nibindi
- Umuvuduko mwinshi wo guhinduranya amashanyarazi, reta ikomeye
- Ibikoresho bya elegitoroniki, icyogajuru, ibikoresho bya elegitoroniki
- Amashanyarazi menshi LED yamurika ibicuruzwa
- Antenna y'itumanaho
