Kusanthula Mlandu--Capel wokhala ndi zaka 15 zaukadaulo waukadaulo

Ma board ozungulira osinthika amapereka mayankho otetezeka komanso odalirika amakampani azachipatala.

Kodi ma board ozungulira a Capel apamwamba kwambiri a 2-layer flexible amathandizira bwanji zida zachipatala monga ma probe a B-ultrasound?

M’dziko lopita patsogolo la masiku ano, luso lazopangapanga lili ndi mbali yofunika kwambiri yopititsa patsogolo mafakitale osiyanasiyana, ndipo nkhani zachipatala zili choncho. Pakati pa zipangizo zamakono zamakono, makina a B-ultrasound akhala akukopa chidwi cha anthu. Chipangizochi chimalola akatswiri azachipatala kuti aziwona zithunzi zenizeni zenizeni za ziwalo zamkati, zomwe zimapangitsa kuti zikhale chida chofunikira kwambiri pozindikira ndi kuyang'anira matenda osiyanasiyana.

Chimodzi mwa zigawo zikuluzikulu za kafukufuku wa B-ultrasound ndi 2-layer flexible printed circuit (FPC). FPC, yomwe imadziwikanso kuti PCB yokhala ndi mbali ziwiri (Printed Circuit Board), ndi bolodi yopyapyala komanso yosinthika yomwe imakhala ngati nsanja yolumikizira zida zamagetsi molumikizana bwino komanso moyenera. FPC yomwe imagwiritsidwa ntchito mu kafukufuku wa ultrasound imapangidwa mwapadera kuti ikwaniritse zofunikira zachipatala, kuonetsetsa kuti ntchito yodalirika komanso yogwira ntchito kwambiri.

Tiyeni tiwone mwatsatanetsatane zatsatanetsatane ndi mawonekedwe a 2-wosanjikiza FPC yomwe imagwiritsidwa ntchito mu kafukufuku wa B-ultrasound. Bolodi ndi 0.1 mm wandiweyani, zomwe zimalola kuti ziphatikizidwe mosavuta pamapangidwe a probe. M'lifupi mwake ndi kutalika kwa mizere ndi 0.06 / 0.08mm, kuwonetsetsa kufalikira kwamphamvu komanso kothandiza. Makulidwe amkuwa a 12um amapereka mphamvu zamagetsi zamagetsi ndikusunga kusinthasintha konse kwa bolodi.

Kuonetsetsa chitetezo chapamwamba kwambiri, FPC ya 2-wosanjikiza yomwe imagwiritsidwa ntchito mu kafukufuku wa ultrasound imapangidwa ndi zinthu zosagwira moto zotchedwa 94V0. Zinthuzi zimalimbana ndi moto kwambiri, zimachepetsa chiopsezo cha ngozi ndi kuwonongeka. Komanso, mankhwala pamwamba FPC utenga kumizidwa golide, amene osati kumawonjezera madutsidwe wa bolodi, komanso ali kwambiri kukana dzimbiri.

Chimodzi mwazinthu zodziwika bwino za 2-wosanjikiza FPC yogwiritsidwa ntchito mu kafukufuku wa B-ultrasound ndi njira yake yapadera yotchedwa chala chopanda golide. Izi zimaphatikizapo kuyika zolumikizira za FPC ndi golide wocheperako kuti alimbikitse kulimba kwawo ndikuwonetsetsa kulumikizana kodalirika. Kukana kuwotcherera mtundu wa FPC ndi wachikasu, zomwe sizimangowonjezera kukopa kowoneka, komanso zimathandizira kuzindikira mwachangu panthawi yopanga ndi kusonkhana.

FPC ya 2-wosanjikiza imayikidwa mu kafukufuku wa B-ultrasound ndipo ndi gawo lofunikira kuti muwonetsetse kuti kujambula kolondola komanso kodalirika. Kusinthasintha kwake kumapangitsa kuti igwirizane ndi mawonekedwe opindika a kafukufuku kuti agwire mosavuta poyang'anira. Makhalidwe apamwamba a FPC, monga kutumiza ma siginecha mwachangu komanso kuwongolera bwino kwamagetsi, kumathandizira kuti magwiridwe antchito onse komanso kulondola kwa ma probe a B-ultrasound.

Mwachidule, 2-wosanjikiza kusinthasintha kusindikizidwa mabwalo asintha zachipatala, makamaka pankhani ya ultrasound probes. Kapangidwe kake kophatikizika, kuwongolera kwamagetsi kwabwino kwambiri, komanso kusinthasintha kumapangitsa kuti ikhale yabwino pachida chachipatala chapamwamba ichi. Ndi mawonekedwe ake ambiri ndi mafotokozedwe opangidwa kuti akwaniritse zofunikira zachipatala, ma FPC amitundu iwiri amagwira ntchito yofunika kwambiri pothandiza akatswiri azachipatala kuti apeze matenda olondola komanso kupereka chithandizo chamankhwala chofunikira.
