Uhlalutyo Lwemeko--I-Capel kunye ne-15 iminyaka yamava obugcisa obuchwephesha

Iibhodi zeesekethe eziguquguqukayo zibonelela ngezisombululo ezikhuselekileyo nezithembekileyo kwishishini lezonyango.

Iibhodi zesekethe eziguquguqukayo zeCapel zibonelela njani ngenkxaso yobugcisa obutsha kwizixhobo zonyango ezifana ne-B-ultrasound probes?

Kweli hlabathi lixakekileyo, ubugcisa bunendima ebalulekileyo ekuphuculeni imizi-mveliso eyahlukahlukeneyo, yaye inkalo yezonyango iyafana. Phakathi kwezixhobo ezininzi zonyango eziphucukileyo, ii-B-ultrasound probes bezisoloko zitsala umdla wabantu. Isixhobo sivumela abaqeqeshi bezonyango ukuba bajonge imifanekiso yexesha langempela yezitho zangaphakathi, okwenza kube sisixhobo esiyimfuneko ekuxilongeni nasekubekeni iliso kwiimeko zonyango ezahlukeneyo.

Enye yezinto eziphambili ze-B-ultrasound probe yi-2-layer flexible printed circuit (FPC). I-FPC, eyaziwa ngokuba yi-PCB enamacala amabini (iBhodi yeSekethe eShicileleyo), ibhodi ebhityileyo neguquguqukayo esebenza njengeqonga lokudibanisa amacandelo e-elektroniki ngendlela edibeneyo nesebenzayo. I-FPC esetyenziswe kwi-ultrasound probe yenzelwe ngokukodwa ukuhlangabezana neemfuno ezifunekayo kwintsimi yezonyango, ukuqinisekisa ukusebenza okuthembekileyo kunye nokusebenza okuphezulu.

Makhe sijonge ngakumbi kwiinkcazo kunye neempawu ze-2-layer FPC ezisetyenziswe kwi-B-ultrasound probe. Ibhodi yi-0.1 mm ubukhulu, evumela ukuba idityaniswe ngokulula kuyilo oludibeneyo lweprobe. Ububanzi bomgca kunye nesithuba somgca yi-0.06 / 0.08mm, iqinisekisa ukuhanjiswa kwesignali ngokukhawuleza nangokufanelekileyo. Ubukhulu bobhedu be-12um bubonelela ngokusebenza kakuhle kombane ngelixa ugcina ukuguquguquka okupheleleyo kwebhodi.

Ukuqinisekisa umgangatho ophezulu wokhuseleko, i-FPC ye-2-layer esetyenziswe kwi-ultrasound probe yenziwe nge-flame-retardant material ebizwa ngokuba yi-94V0. Esi sixhobo sinokumelana nomlilo kakhulu, sinciphisa umngcipheko weengozi kunye nomonakalo. Ukongeza, unyango olungaphezulu lwe-FPC lwamkela igolide yokuntywiliselwa, enganyusi nje kuphela ukuqhutywa kwebhodi, kodwa inokumelana nokugqwesa okugqwesileyo.

Enye yezinto eziphawulekayo ze-2-layer FPC esetyenziswa kwi-B-ultrasound probe yinkqubo yayo ekhethekileyo ebizwa ngokuba ngumnwe wegolide ongenanto. Le nkqubo ibandakanya ukwaleka izihlanganisi ze-FPC kunye nomaleko obhityileyo wegolide ukomeleza ukuqina kwazo kunye nokuqinisekisa uqhagamshelo oluthembekileyo. Umbala ochasayo we-welding we-FPC utyheli, ongongezi nje ukubhenela okubonakalayo, kodwa uququzelela ukuchongwa okukhawulezayo ngexesha lokuvelisa kunye nokuhlanganisa.

I-2-layer FPC isetyenziswe kwi-probe ye-B-ultrasound kwaye iyingxenye ebalulekileyo yokuqinisekisa ukulinganisa okuchanekileyo nokuthembekileyo. Ukuguquguquka kwayo kuvumela ukuba ihambelane nemilo egobileyo yeprobe yokuphatha lula ngexesha lokuhlola. Iimpawu eziphezulu ze-FPC, ezifana nokuhanjiswa kwesignali ekhawulezayo kunye ne-conductivity egqwesileyo yombane, igalelo ekusebenzeni kakuhle kunye nokuchaneka kwe-B-ultrasound probes.

Isishwankathelo, iisekethe eziprintiweyo ezi-2 eziguquguqukayo ziye zaguqula icandelo lezonyango, ngakumbi kwintsimi ye-ultrasound probes. Uyilo lwayo olubambeneyo, ukuhanjiswa kombane okugqwesileyo, kunye nokuguquguquka kuyenza ilunge kwesi sixhobo sonyango siphambili. Ngeempawu zayo ezininzi kunye neenkcukacha ezilungiselelwe ukuhlangabezana neemfuno ezingqongqo zecandelo lezonyango, i-2-layer FPCs idlala indima ebalulekileyo ekuncedeni iingcali zonyango zibonelele ngoxilongo oluchanekileyo kunye nokubonelela ngononophelo lwezonyango oluyimfuneko.
