Ukuhlolwa kwe-Flying probe

Isihloli senaliti esindizayo asincikile kuphethini yephinikhodi ekhwezwe ku-fixture noma kubakaki.Ngokusekelwe kule sistimu, ama-probe amabili noma ngaphezulu afakwe emakhanda amancane, ahamba mahhala endizeni ye-xy, futhi amaphuzu okuhlola alawulwa ngokuqondile yi-CADI. Idatha ye-Gerber.Ama-probe akabili angahamba phakathi kwe-4 mil enye kwenye.Ama-probe angakwazi ukuhamba ngokuzenzekelayo, futhi awukho umkhawulo wangempela wokuthi angasondelana kangakanani.Umhloli onezingalo ezimbili ezinyakazayo usekelwe esilinganisweni somthamo. ibhodi lesifunda libekwe ngokuqinile phezu kongqimba lwe-insulating epuleti yensimbi eyenza njengenye ipuleti yensimbi ye-capacitor.Uma kukhona isifunda esifushane phakathi kwemigqa, i-capacitance izoba nkulu kunephuzu elithile.Uma kukhona ukuphumula, amandla azoba mancane.

Ijubane lokuhlola liwumbandela obalulekile wokukhetha umhloli.Ngenkathi umhloli wenaliti yenaliti engahlola ngokunembile izinkulungwane zamaphoyinti okuhlola ngesikhathi, umhloli wenaliti endizayo angahlola amaphuzu amabili noma amane kuphela ngesikhathi.Ngaphezu kwalokho, ukuhlola okukodwa nge umhloli wenaliti yenaliti angabiza kuphela ama-20-305, kuye ngobunkimbinkimbi bebhodi, kanti umhloli wenaliti endizayo udinga u-Ih noma ngaphezulu ukuqedela ukuhlola okufanayo. U-Shipley (1991) wachaza ukuthi le ndlela iyisinqumo esihle kubakhiqizi bamabhodi esekethe ayinkimbinkimbi anesivuno esiphansi, noma ngabe abakhiqizi bamabhodi esekethe aphrintiwe aphezulu bebheka indlela yokuhlola iphini elindizayo elihambayo njengelihamba kancane.

Ekuhloleni ipuleti elingenalutho, kukhona amathuluzi okuhlola azinikele (Lea, 1990).Indlela engabizi kakhulu kungaba ukusebenzisa ithuluzi elisebenza emhlabeni wonke, nakuba ekuqaleni libiza kakhulu kunethuluzi elizinikele, izindleko zalo zokuqala eziphezulu zizonxeshezelwa ngokuncipha izindleko zokucushwa ngakunye.Ngokwenjongo evamile yamagridi, igridi evamile yamabhodi nezinto zokukhweza ngaphezulu ezinezici zamaphini ngu-2.5 mm.Kuleli qophelo iphedi yokuhlola kufanele ibe nkulu noma ilingane no-1.3mm.

Kugridi ye-Imm, iphedi yokuhlola iklanyelwe ukuba ibe nkulu kuno-0.7mm.Uma igridi incane, iphinikhodi yokuhlola incane, i-brittle, futhi ijwayele ukulimala.Ngakho-ke, kungcono kakhulu ukusebenzisa amagridi amakhulu kuno-2.5mm.Crum (1994b) uthe inhlanganisela yesihloli se-universal (umhloli wegridi ojwayelekile) nesihloli senaliti endizayo singenza ukutholwa kwebhodi lesifunda eliminyana kakhulu kube okunembile futhi ukonga.Enye indlela ayiphakamisayo ukusebenzisa isihloli senjoloba esisebenzayo, esingasetshenziswa ukuthola amaphuzu achezuka kugridi.Nokho, ukuphakama okuhlukene kwamaphedi aphathwa ngokulingana komoya oshisayo kuzovimbela ukuxhunywa kwamaphuzu okuhlola.
Amaleveli amathathu alandelayo okutholwa ngokuvamile ayenziwa:
1) ukutholwa kwepuleti elinqunu;
2) ukutholwa ku-inthanethi;
3) ukutholwa kokusebenza.
Umhloli wohlobo olujwayelekile lungasetshenziswa ukuthola uhlobo lwesitayela nohlobo lwebhodi lesifunda kanye nezinhlelo zokusebenza ezikhethekile.
Izindwangu zensimbi ezivamile yilezi:
Ithusi
Ithini

Ubukhulu ngokuvamile buphakathi kuka-5 no-15 cm
Ingxubevange ye-lead-tin (noma i-tin-copper alloy)
Okusho ukuthi, i-solder, ngokuvamile i-5 kuya ku-25 m ubukhulu, nokuqukethwe kwethini okungaba ngu-63%

igolide: Imvamisa izogqitshwa kuphela kusixhumi esibonakalayo

isiliva:Imvamisa izogqitshwa kuphela kusixhumi esibonakalayo, noma yonke iphinde ibe yingxubevange yesiliva
