Ukuhlaziywa Kwecala--UCapel uneminyaka engu-15 yesipiliyoni sobuchwepheshe

Amabhodi wesifunda aguquguqukayo ahlinzeka ngezixazululo eziphephile nezithembekile embonini yezokwelapha.

Amabhodi esekethe e-Capel anembayo ephezulu anengqimba engu-2 ahlinzeka kanjani ngosekelo olusha lobuchwepheshe lwemishini yezokwelapha efana nama-B-ultrasound probes?

Ezweni lanamuhla elisheshayo, ubuchwepheshe budlala indima ebalulekile ekuthuthukiseni izimboni ezihlukahlukene, futhi umkhakha wezokwelapha uyafana. Phakathi kwemishini eminingi yezokwelapha ethuthukisiwe, ama-B-ultrasound probe abelokhu edonsa ukunaka kwabantu. Idivayisi ivumela ochwepheshe bezokwelapha ukuthi babuke izithombe zesikhathi sangempela zezitho zangaphakathi, okuyenza ibe ithuluzi elibalulekile lokuxilonga nokuqapha izimo zezokwelapha ezihlukahlukene.

Enye yezingxenye ezibalulekile ze-B-ultrasound probe iyisekhethi ephrintiwe enezingqimba ezi-2 (FPC). I-FPC, eyaziwa nangokuthi i-PCB enamacala amabili (Ibhodi Lesekethe Eliphrintiwe), iyibhodi elincanyana neliguquguqukayo elisebenza njengenkundla yokuxhuma izingxenye ze-elekthronikhi ngendlela ehlangene nephumelelayo. I-FPC esetshenziswe ku-ultrasound probe iklanyelwe ngokukhethekile ukuhlangabezana nezidingo ezidingekayo zenkundla yezokwelapha, iqinisekisa ukusebenza okuthembekile nokusebenza okuphezulu.

Ake sihlolisise ukucaciswa kanye nezici ze-FPC enezingqimba ezi-2 ezisetshenziswa kuphenyi lwe-B-ultrasound. Ibhodi liwugqinsi elingu-0.1 mm, elivumela ukuthi lihlanganiswe kalula nomklamo ohlangene we-probe. Ububanzi bomugqa nesikhala somugqa ngu-0.06/0.08mm, okuqinisekisa ukudluliswa kwesignali okusheshayo nangempumelelo. Ugqinsi lwethusi oluyi-12um luhlinzeka ngokusebenza kahle kukagesi ngenkathi kugcinwa ukuguquguquka okuphelele kwebhodi.

Ukuqinisekisa izinga eliphezulu lokuphepha, i-FPC enezingqimba ezi-2 esetshenziswa kuphenyi lwe-ultrasound yakhiwe ngento ebamba ilangabi ebizwa ngokuthi i-94V0. Le nto ikwazi ukumelana nomlilo kakhulu, inciphisa ubungozi bezingozi nomonakalo. Ngaphezu kwalokho, ukwelashwa okungaphezulu kwe-FPC kusebenzisa igolide lokucwiliswa, elingagcini nje ukuthuthukisa ukuqhutshwa kwebhodi, kodwa futhi linokumelana okuhle kakhulu kokugqwala.

Esinye sezici eziphawulekayo ze-FPC enezingqimba ezi-2 ezisetshenziswa kuphenyi lwe-B-ultrasound inqubo yayo ekhethekile ebizwa ngokuthi umunwe wegolide ongenalutho. Le nqubo ibandakanya ukunamathisela izixhumi ze-FPC ngongqimba oluncane lwegolide ukuze kuthuthukiswe ukuqina kwazo nokuqinisekisa ukuxhumana okuthembekile. Umbala we-welding wokumelana we-FPC uphuzi, ongagcini nje ngokungeza ukukhanga okubonakalayo, kodwa futhi kusiza ukuhlonza okusheshayo ngesikhathi sokukhiqiza nokuhlanganisa.

I-FPC enezingqimba ezi-2 isetshenziswa ku-B-ultrasound probe futhi iyingxenye ebalulekile yokuqinisekisa ukuthwebula okunembile nokuthembekile. Ukuguquguquka kwayo kuyivumela ukuthi ihambisane nokuma okugobile kwe-probe ukuze iphatheke kalula ngesikhathi sokuhlolwa. Izici zokusebenza okuphezulu kwe-FPC, njengokudluliswa kwesignali okusheshayo kanye nokuhamba kahle kukagesi, kunomthelela ekusebenzeni kahle okuphelele nokunemba kwama-B-ultrasound probes.

Kafushane, amasekhethi aphrintiwe anezingqimba ezi-2 aguqule insimu yezokwelapha, ikakhulukazi emkhakheni we-ultrasound probes. Idizayini yayo ehlangene, ukuhanjiswa kukagesi okuhle kakhulu, nokuguquguquka kuyenza ilungele le divayisi yezokwelapha ethuthukisiwe. Ngezici zayo eziningi kanye nokucaciswa okuklanyelwe ukuhlangabezana nezidingo eziqinile zenkundla yezokwelapha, ama-FPC anezingqimba ezimbili adlala indima ebalulekile ekusizeni ochwepheshe bezokwelapha ukuba banikeze ukuxilonga okunembile futhi balethe ukunakekelwa kwezokwelapha okudingekayo.
