Mabodi Osindikizidwa Olimba-Flex: Njira Zitatu Zoyeretsera M'mabowo

M'mabokosi osindikizidwa okhwima, chifukwa cha kusakanizidwa bwino kwa zokutira pa khoma la dzenje (filimu yoyera ya rabara ndi pepala lomangirira), n'zosavuta kuchititsa kuti chophimbacho chilekanike ndi khoma la dzenje pamene chikugwedezeka ndi kutentha. , kumafunanso kupuma kwa pafupifupi 20 μm, kotero kuti mphete yamkati yamkuwa ndi mkuwa wa electroplated ndi odalirika kwambiri kukhudzana ndi mfundo zitatu, zomwe zimathandizira kwambiri kukana kwa kutentha kwazitsulo zazitsulo. Capel yotsatirayi ikufotokozerani mwatsatanetsatane. Masitepe atatu otsuka dzenje mutabowola bolodi lokhazikika.

Kudziwa kuyeretsa mkati mwa dzenje mutabowola ma flex flex circuits:

Popeza polyimide siimagonjetsedwa ndi alkali wamphamvu, desmear yamphamvu yamchere ya potassium permanganate desmear si yoyenera matabwa osinthika komanso okhwima. Nthawi zambiri, dothi lobowola pa bolodi lofewa komanso lolimba liyenera kutsukidwa ndi plasma yoyeretsa, yomwe imagawidwa m'magawo atatu:

(1) Zida zikafika pamlingo wina wa vacuum, nayitrogeni yoyera kwambiri komanso mpweya wabwino kwambiri amabayidwamo molingana, ntchito yayikulu ndikuyeretsa khoma la dzenje, kutenthetsera bolodi losindikizidwa, ndikupanga zinthu za polima. kukhala ndi ntchito inayake, yomwe ili yopindulitsa Pambuyo pokonza. Nthawi zambiri, ndi 80 digiri Celsius ndipo nthawi ndi mphindi 10.

(2) CF4, O2 ndi Nz anachita ndi utomoni monga mpweya choyambirira kukwaniritsa cholinga decontamination ndi etch mmbuyo, zambiri pa 85 digiri Celsius ndi kwa mphindi 35.

(3) O2 amagwiritsidwa ntchito ngati mpweya woyambirira kuchotsa zotsalira kapena "fumbi" lomwe linapangidwa pazigawo ziwiri zoyambirira za chithandizo; yeretsani khoma la dzenje.

Koma ndizofunika kudziwa kuti pamene madzi a m'magazi amagwiritsidwa ntchito kuchotsa dothi lobowola m'mabowo a matabwa amitundu yambiri osinthika komanso okhwima, kuthamanga kwa zipangizo zosiyanasiyana kumakhala kosiyana, ndipo dongosolo laling'ono ndi lalikulu ndi: acrylic film. , epoxy resin , polyimide, fiberglass ndi mkuwa. Mitu ya ulusi wagalasi yotuluka ndi mphete zamkuwa zitha kuwoneka bwino pakhoma la dzenje kuchokera pa maikulosikopu.

Pofuna kuonetsetsa kuti electroless mkuwa plating njira angathe kukhudzana kwathunthu dzenje khoma, kuti wosanjikiza mkuwa si kutulutsa voids ndi voids, zotsalira za plasma anachita, chotuluka galasi CHIKWANGWANI ndi polyimide filimu pa dzenje khoma ayenera kukhala. kuchotsedwa. Njira yochizira imaphatikizapo njira zamakina zamakina ndi makina kapena kuphatikiza ziwirizi. Njira yopangira mankhwala ndikunyowetsa bolodi losindikizidwa ndi yankho la ammonium hydrogen fluoride, ndiyeno gwiritsani ntchito ionic surfactant (KOH solution) kuti musinthe kuchuluka kwa khoma la dzenje.

Njira zamakina zimaphatikizirapo kuphulika kwa mchenga wonyowa kwambiri komanso kutsuka kwamadzi mothamanga kwambiri. Kuphatikiza kwa mankhwala ndi njira zamakina zimakhala ndi zotsatira zabwino kwambiri. Lipoti la metallographic limasonyeza kuti mkhalidwe wa khoma lazitsulo pambuyo pa kuchotsedwa kwa plasma ndi wokhutiritsa.

Zomwe zili pamwambazi ndi njira zitatu zoyeretsera mkati mwa dzenje pambuyo pobowola matabwa okhwima-flex osindikizidwa mosamala ndi Capel. Capel wakhala akuyang'ana pa bolodi losindikizidwa losindikizidwa, bolodi yofewa, bolodi lolimba ndi msonkhano wa SMT kwa zaka 15, ndipo wapeza chidziwitso chochuluka chaukadaulo mumakampani a board board. Ndikukhulupirira kuti kugawana uku ndikothandiza kwa aliyense. Ngati muli ndi mafunso ena a board board, chonde funsani gulu lathu laukadaulo la Capel makeup kuti likupatseni chithandizo chaukadaulo pantchito yanu.
