PCB Flying Probe Muedzo: Chii? Rinoshanda Sei?

Chii chinonzi PCB Flying Probe Test

Iyo PCB Flying Probe Test inzira yepamberi inoshandiswa muindasitiri yekugadzira zvemagetsi yekuyedza mashandiro emagetsi ePrinted Circuit Boards (PCBs). Yakatumidzwa kushandiswa kwayo kwakasiyana kwemaprobes anofambika ayo 'anobhururuka' pamusoro pePCB kuti abatane neakasiyana mapoinzi, iyi bvunzo ibwe repakona mukuona kunaka uye kuvimbika kwePCBs.

Kuedza kwekuongorora mafambiro emhepo kunonyanya kushanda kana dhizaini yacho ichisiya mambure anowanikwa uye chinangwa chekuedza chakajeka, saka chinofanira kurongwa nezvinodiwa zvekuongorora magetsi ePCB uye, kuti zvishande zvakanaka, nzira yakakodzera yekuyedza PCBA.

Kusiyana nenzira dzechinyakare dzekuyedza dzinoshandisa zvigadziriso zvekuyedza (semubhedha wezvipikiri), bvunzo yekubhururuka ino shandisa akati wandei emaoko marobhoti akashongedzerwa nemaprobe chaiwo. Aya maprobe akarongwa kuti aende kune chaiwo mapoinzi paPCB kuti aite bvunzo.

Iko Kukosha muPCB Kugadzira

• Kuona Kukanganisa Kwekugadzira: Chinangwa chikuru chekubhururuka chekuongorora bvunzo ndechekuona kukanganisa kwekugadzira senge akavhurika maseketi, mapfupi maseketi, uye zvinhu zvechikamu. Inonyanya kushanda kune yakaoma PCBs uko tsika dzekuyedza nzira dzinogona kupfupika.
• Versatility uye Flexibility: Iyi nzira inochinjika zvakanyanya kune akasiyana PCB magadzirirwo pasina kudiwa kwetsika zvigadziriso. Inogona kurongwazve kune akasiyana PCB marongero, ichiita kuti ive yakanakira prototyping uye diki kusvika pakati pekugadzira inomhanya.
• Kuedza Kusina Kuparadza: Iyo yekubhururuka probe bvunzo inzira isingaparadze, zvichireva kuti inoedza PCB pasina kukuvadza. Izvi zvakakosha pakuchengetedza kutendeseka kwebhodhi, kunyanya mumashandisirwo akatetepa kana emhando yepamusoro.

Iyo PCB Flying Probe Test Inoshanda Sei?

Danho 1: Setup uye Kuronga

Pakutanga, iyo chaiyo PCB dhizaini inoiswa muyedzo software. Izvi zvinosanganisira PCB marongerwo uye hunhu hwemagetsi hunotarisirwa pane yega yega test point.
Iyo software inobva yagadzira kutevedzana kwekuyedza, kuronga mafambiro emaprobes kuti aenderane nehurongwa hwePCB.

Danho 2: Bata uye kuyerwa

Panguva yekuyedzwa, maprobes anobata zvinyoro nyoro mapoinzi ebvunzo paPCB. Iwo mapoinzi ebvunzo anogona kusanganisira echikamu mapedhi, vias, kana chero imwe conductive chikamu chePCB.
Iwo maprobes anoyera akasiyana emagetsi zvimiro, sekuenderera mberi, kuramba, capacitance, uye dzimwe nguva zvakanyanya kuoma ma paramita senge frequency mhinduro kana logic kushanda.

Danho rechitatu: Kuongorora uye Kushuma

Mushure mekuunganidza data, sisitimu inoongorora mibairo nekuienzanisa nemhedzisiro inotarisirwa inotsanangurwa muPCB dhizaini.
Chero kusawirirana kana kusawirirana kunoonekwa kunocherechedzwa. Izvi zvinogona kuratidza zvingangoitika senge mapfupi maseketi, akavhurika maseketi, kana akaremara zvikamu.

Flying Probe Test VS Traditional Methods

Yechinyakare PCB kuyedzwa kazhinji inosanganisira nzira dzakaita seye 'Bed of Nails' tester. Iyi sisitimu inoshandisa chigadziriso chine mapini akawanda (zvipikiri) anofambirana nenzvimbo dzekuyedza paPCB. Kana iyo PCB ichidzvanywa ichipikisa mapini aya, bvunzo dzemagetsi dzinoitwa mukati mebhodhi.

Flexibility uye Setup Nguva

Flying Probe Test: Inopa kuchinjika kwakasarudzika, sezvo isingade zvigadziriso zvetsika. Iyo nguva yekumisikidza yakaderedzwa zvakanyanya, sezvo bvunzo chirongwa chakavakirwa paPCB dhizaini mafaera. Izvi zvinoita kuti ive yakanaka kune prototypes uye diki yekugadzira inomhanya uko dhizaini shanduko inowanzoitika.
Nzira dzechinyakare: Iyo yekumisikidza inosanganisira kugadzira chimiro chetsika, chinogona kutora nguva uye chinodhura. Iyi nzira inonyanya kukodzera kugadzirwa kwakakura uko dhizaini inopedzwa uye isingachinji pazvikamu zvakawanda.

Zvinokosha Mutengo

Flying Probe Test: Nepo mutengo wekutanga wekubhururuka probe tester uchigona kunge wakakwira, zvinobvisa kudiwa kwezvigadziriso zvekuyedza, zvichiita kuti zvive zvakanyanya kudhura kune yakaderera-vhoriyamu kana akasiyana zvigadzirwa.
Maitiro echinyakare: Inoda yakakosha kudyara kwepamberi mumagadzirirwo etsika. Zvisinei, pakugadzirwa kwepamusoro-soro, mari iyi inoderedzwa pamusoro pezvikamu zvakawanda, zvichiita kuti zvive nehupfumi munguva refu.

Kuedza Kugona

Flying Probe Test: Inokwanisa kuita yakadzama uye chaiyo bvunzo. Inogona kuchinjika nyore nyore kuyedza maPCB akasiyana, ichiita kuti ive yakasiyana-siyana yekuyedza yakaoma kana kuzara mabhodhi.
Tsika dzechinyakare: Kunyange dzichishanda pakuyedzwa zvakajairika, dzinogona kusaenderana nemazvo evayedzeri vanobhururuka, kunyanya kune maPCB akaomarara kana akaomarara.

Kumhanya uye Kupfuura

Flying Probe Bvunzo: Kazhinji inononoka kupfuura nzira dzechinyakare nekuda kwenguva inotorwa kuti probes ifambe uye kuyedza mapoinzi akasiyana. Yakanyatsokodzera mamiriro ekuti kumhanya kwekuyedza kusinganyanyi kukosha pane kuchinjika.
Nzira dzechinyakare: Ipa kukurumidza kuyedzwa paPCB, zvichiita kuti ive yakanyanya kunaka pakugadzira-vhoriyamu kugadzirwa uko kwakafanana dhizaini inoedzwa kakawanda.

Hunhu uye Kuvimbika

Flying Probe Muedzo: Inopa yemhando yepamusoro kuyedzwa nekuongorora kwakadzama. Kugona kwayo kukurumidza kuchinjika kune dhizaini shanduko inovimbisa kunyatsoyedzwa kune yega yega yakasarudzika PCB.
Nzira dzechinyakare: Kuvimbika pakuyedzwa kunoenderana kwemayunifomu maPCB. Nekudaro, ivo vangasave vanobudirira pakuona mamwe marudzi ehurema pamabhodhi akaoma kana asiri-standard.
