Ikibaho cyumuzunguruko Ceramic Gukora: Nibihe bikoresho bikoreshwa?

Muri iyi nyandiko ya blog, tuzasesengura ibikoresho byingenzi bikoreshwa mugukora imbaho ​​zumuzunguruko wa ceramic hanyuma tuganire nakamaro kazo kugirango tugere kumikorere myiza.

Mu musaruro wibibaho byumuzunguruko, ibikoresho bitandukanye bigira uruhare runini mugukora neza no kwizerwa. Ikibaho cyumuzunguruko cyitwa Ceramic, kizwi kandi nka ceramic cyacapwe cyumuzunguruko (PCBs), gikoreshwa cyane mubikorwa bitandukanye birimo ibikoresho bya elegitoroniki, icyogajuru hamwe n’imodoka bitewe nubushyuhe bwiza bwumuriro, ubushyuhe bukabije bwo gukora hamwe nubushobozi bwamashanyarazi.

Ikibaho cyumuzunguruko ceramic kigizwe ahanini nuruvange rwibikoresho byubutaka nicyuma, byatoranijwe neza kugirango byuzuze ibisabwa byihariye bya porogaramu zitandukanye.

1. Ceramic substrate:

Urufatiro rwibibaho byumuzunguruko ni ceramic substrate, itanga umusingi kubindi bice byose. Aluminium oxyde (Al2O3) na nitride ya aluminium (AlN) nibikoresho bikoreshwa cyane mubutaka. Alumina ifite imbaraga zubukorikori buhebuje, ubushyuhe bwo hejuru bwumuriro nubushakashatsi bwiza bwamashanyarazi, bigatuma bukoreshwa muburyo butandukanye. Ku rundi ruhande, nitride ya aluminium, itanga uburyo bwiza bwo gukwirakwiza ubushyuhe no kwagura ubushyuhe, bigatuma biba byiza kubisabwa bisaba gusohora neza.

2. Inzira ziyobora:

Inzira ziyobora zishinzwe gutwara ibimenyetso byamashanyarazi hagati yibice bitandukanye kurubaho. Mubibaho byumuzunguruko wububiko, ibyuma byuma nka zahabu, ifeza, cyangwa umuringa bikoreshwa mugukora ibyo bimenyetso. Ibyo byuma byatoranijwe kubera amashanyarazi menshi kandi ahuza na ceramic substrate. Zahabu muri rusange itoneshwa kubera kurwanya kwangirika kwayo hamwe nu mashanyarazi ahamye, cyane cyane mubikorwa byinshi.

3. Igice cya dielectric:

Inzira ya dielectric ningirakamaro mugukingira inzira ziyobora no gukumira ibimenyetso bitavangira hamwe numuyoboro mugufi. Ibikoresho bya dielectric bikunze gukoreshwa mubibaho byumuzunguruko wa ceramic ni ikirahure. Ikirahure gifite ibikoresho byiza byamashanyarazi kandi birashobora kubikwa nkurwego ruto kuri ceramic substrates. Byongeye kandi, ikirahuri kirashobora guhindurwa kugira agaciro ka dielectric gahoraho gahoraho, bigatuma igenzura neza imiterere yamashanyarazi yibibaho.

4. Maskeri yo kugurisha no kuvura hejuru:

Mask ya Solder ishyirwa hejuru yumurongo wogukingira kugirango ubarinde ibintu bidukikije nkumukungugu, ubushuhe, na okiside. Iyi masike mubusanzwe ikozwe muri epoxy cyangwa polyurethane ishingiye kubikoresho bitanga ubwirinzi no kurinda. Koresha uburyo bwo kuvura hejuru nko kwibiza amabati cyangwa zahabu kugirango wongere ubushobozi bwikibaho kandi wirinde okiside yumuringa wagaragaye.

5. Binyuze mu kuzuza ibikoresho:

Vias ni ibyobo bito byacukuwe mu kibaho cyizunguruka cyemerera guhuza amashanyarazi hagati yuburyo butandukanye. Mubibaho byumuzunguruko, hifashishijwe ibikoresho byuzuye byuzuza ibyo byobo no kwemeza amashanyarazi yizewe. Bisanzwe binyuze mu kuzuza ibikoresho birimo paste ziyobora cyangwa kuzuza bikozwe mu ifeza, umuringa cyangwa ibindi byuma, bivanze nikirahure cyangwa ceramic. Ihuriro ritanga amashanyarazi nubukanishi, byemeza isano ikomeye hagati yinzego zitandukanye.

Muri make

Umusaruro wibibaho byumuzunguruko urimo guhuza ibikoresho byubutaka, ibyuma nibindi bintu byihariye. Aluminium oxyde na nitride ya aluminiyumu ikoreshwa nka substrate, naho ibyuma nka zahabu, ifeza n'umuringa bikoreshwa mu gushakisha inzira. Ikirahuri gikora nk'ibikoresho bya dielectric, bitanga amashanyarazi, kandi masike yo kugurisha epoxy cyangwa polyurethane irinda inzira ziyobora. Ihuza hagati yuburyo butandukanye rishyirwaho binyuze mubintu byuzuye bigizwe na paste yuyobora hamwe nuwuzuza.

Gusobanukirwa ibikoresho bikoreshwa mugukora imbaho ​​zumuzunguruko wa ceramic ningirakamaro kubashakashatsi nabashushanya guteza imbere ibikoresho bya elegitoroniki bikora neza kandi byizewe. Guhitamo ibikoresho bikwiye biterwa nibisabwa byihariye nkubushyuhe bwumuriro, ibikoresho byamashanyarazi nibidukikije. Mugukoresha imiterere yihariye ya buri kintu, imbaho ​​zumuzunguruko zikomeza guhinduranya inganda zitandukanye nibikorwa byazo byiza kandi biramba.
