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-2-layer FPC esetyenziswe kwiprobe ye-ultrasound 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 wokuchasana 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 ilungele esi 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.
