Pfuma yebvunzo mune PCB ndeyekufumurwa pasuru iyo inogona kushandiswa kutarisa kuti redunhu riri kushanda kuti riitwe. Munguva yekugadzira, vashandisi vanogona jekista test test vasaini kuburikidza neProbes kuburikidza neyebvunzo mapoinzi kuti uone zvinogoneka nyaya. Iyo bvunzo yemubhadharo inobuda inosarudza kana chiratidzo chakapihwa chakaderera / chakakwira kana uchienzaniswa nemhedzisiro yaunoda uye shanduko dzakakwana dzinogona kuitwa zvakafanana.

The thePCB bvunzo pointinofanira kunge iri panzvimbo yekunze kwebhodhi. Izvi zvinobvumira iyo bvunzo michina probes kushandisa nayo uye kuitisa bvunzo. Iyo bvunzo probe matipi inowanikwa mumhando dzakasiyana siyana kune dzakasiyana dzekuyedza nzvimbo (flat, spherical, conical, etc) iyo yekubvunzurudza yebhodhi kuti ienderane neiyo probe yakanakira iyo. Izvi zvinobvumira vagadziri kuti vatarise iyo iripo gla-gomba mapini uye vias pamabhodhi seyekuedzwa.

Mhando dzeNzvimbo dzebvunzo

Probe Test Point

Rudzi rwekutanga rwebvunzo pane nzvimbo inowanikwa nyore nyore iyo inogona kuwanikwa neiyo nyanzvi uchishandisa mudziyo wakatemerwa kana probe. Idzi pfungwa dzebvunzo dzinogona kuzivikanwa zvakadai se "GNG", "pwr" etc. Iyo probe bvunzo inoitwa yekuita nzvimbo yekutsvaga ie yekupa ruzivo urwu uye idzo idzo idzo.

Otomatiki bvunzo mapoinzi

Iyo yechipiri mhando yeyedzo point inoshandiswa kune otomatiki bvunzo michina. Iyo automated bvunzo mapoinzi pane PCB ndeye vias, gla-gla-gomba mapini, uye madiki ekutora mapuru esimbi akagadzirirwa kuti agare mishonga ye automated test system. Automated bvunzo mapoinzi anotendera automated bvunzo maitiro ayo anoshandisa otomatiki bvunzo probes. Ivo ndevemhando nhatu:

1. Bare Bhodhi Kuedza.

2. In-Circuit Kuedza (ICT):Iyo ct erT inoitwa kuti ive nechokwadi chekuti zvese zvikamu zviripo pane bhodhi zviri kushanda sezvavanofanira. Probes kubva kuKuyedza Kugadziriswa kuchauya kuzosangana neyedzo bvunzo pamabhodhi edunhu kuti aite bvunzo.

3. Kubhururuka Probe kuyedza (FPT):Kubhururuka Probe Kuongororwa (FPT) muedzo automated unoshandiswa kuongorora kushanda kwakakodzera kwezvinhu pane PCB Bhodhi. Muedzo iyi, mapuranga maviri kana anopfuura akarongwa kuti afambe nebhodhi mumhepo uye kuwana chikamu chakasiyana-siyana cheinso kusvika pakuona zvikanganiso, zvipfupi, zvinokatyamadza, tsika dzekudzivirira, uye chikamu chekusangana.

Zvinhu zvekufunga nezvazvo uchiita pikicha yebvunzo pane PCB:

● Test Point Kugoverwa: Pfungwa dzeAyedzo dzinofanirwa kugoverwa zvakaringana muPCB kuti zviongororwe zvakawanda zvinogona kuitwa panguva imwe chete.
● BHUKU REMAKARA: ZVINHU ZVINOGONESA ZVINOGONA KUTI VAVANZWA PAKATI PCB iyo inobatsira mukuchengetedza nguva nemari.
.

Zvakanakira zvekuwedzera bvunzo mapoinzi kune PCB:

● Kuongororwa kuri nyore kukanganisa
● NGUVA YEMADZIMAI
● Zviri nyore kuita

Pfungwa dzekuyedza dzakakosha pakuratidza kutendeka kwePCB. Huwandu hweyedzo pane PCB Bhodhi rinofanirwa kuve rakaganhurirwa sezvo ivo vari nzvimbo yakaburitswa yenzara iyo yaigona kupfupi netsaona kune imwe nzvimbo yekubvunzana muhupedyo uye kukanganisa dunhu.
