Chii chinonzi kubhururuka probe bvunzo yedare redunhu? Chii chinoita? Ichi chinyorwa chinokupa tsananguro yakadzama yekubhururuka kuferefeta bvunzo yedunhu redunhu, pamwe nemusimboti weiyo inobhururuka probe bvunzo uye zvikonzero zvinoita kuti gomba rivharwe. Present.
Nheyo yedare redunhu inobhururuka probe bvunzo iri nyore kwazvo. Inongoda maprobe maviri ekufambisa x, y, z kuyedza mapoinzi maviri edunhu rega rega rimwe nerimwe, saka hapana chikonzero chekugadzira zvimwe zvinodhura. Nekudaro, nekuti iri bvunzo yekupedzisira, iyo yekumhanyisa bvunzo inononoka zvakanyanya, ingangoita gumi-40 mapoinzi/sec, saka inonyanya kukodzera masampuli uye diki kugadzirwa kwemazhinji; maererano nehuwandu hwekuyedza, bvunzo yekubhururuka inogona kuiswa kune yakanyanya density board, senge MCM.
Nheyo yeinobhururuka probe tester: Inoshandisa 4 probes kuitisa yakakwira-voltage insulation uye yakaderera-resistance kuenderera bvunzo (kuyedza yakavhurika dunhu uye pfupi dunhu redunhu) pabhodhi redunhu, chero faira rekuyedza rinoumbwa ne iyo mutengi manyoro uye yedu engineering manyoro.
Pane zvikonzero zvina zvedunhu pfupi uye rakavhurika redunhu mushure mebvunzo:
1. Mafaira emutengi: muchina wekuedza unogona kushandiswa chete kuenzanisa, kwete kuongorora
2. Kugadzirwa kwemutsara wekugadzira: PCB board warpage, solder mask, mavara asina kukwana
3. Gadzira shanduko yedata: kambani yedu inotora engineering dhizaini bvunzo, imwe data (kuburikidza) yeinjiniya dhizaini inosiiwa.
4. Equipment factor: software uye hardware matambudziko
Pawakagamuchira bhodhi iro isu takaedza uye tikapasa chigamba, wakasangana nekutadza kwegomba. Handizivi kuti chii chakakonzera kusanzwisisana kwatakaita kuti tirege kuiedza tikaitumira. Muchokwadi, kune zvikonzero zvakawanda zvekutadza kweVia hole.
Pane zvikonzero zvina zveizvi:
1. Kukanganisa kunokonzerwa nekuchera: bhodhi inogadzirwa ne epoxy resin uye girazi fiber. Mushure mokuchera kuburikidza negomba, pachava neguruva rinosara mugomba, risina kucheneswa, uye mhangura haigoni kunyura mushure mekuporesa. Kazhinji, isu tiri kubhururuka netsono kuyedzwa mune ino kesi Iyo link inozoedzwa.
2. Kukanganisa kunokonzerwa nekunyura kwemhangura: nguva yekunyura mhangura ipfupi, gomba remhangura harina kuzara, uye gomba remhangura harina kuzara kana tini yakanyunguduka, zvichiita kuti pave nemamiriro ezvinhu akaipa. (Mukunaya kwekemikari yemhangura, pane matambudziko mukubvisa slag, alkaline degreasing, micro-etching, activation, kukurumidza, uye kunyura kwemhangura, senge budiriro isina kukwana, kuwandisa kwakadzika, uye mvura yakasara mugomba haina kugezwa. yakachena.
3. The redunhu bhodhi vias zvinoda yakawandisa ikozvino, uye kudiwa gobvu gomba mhangura haina kuziviswa pachine. Mushure mekunge simba ravhurwa, ikozvino yakakura zvakanyanya kunyungudutsa gomba mhangura. Dambudziko iri rinowanzoitika. Theoretical current haina kuenzana neazvino chaiwo. Nekuda kweizvozvo, iyo mhangura yegomba yakanyungudutswa yakananga mushure mesimba, izvo zvakakonzera kuti via viavharwe uye zvakakanganisika nekusayedzwa.
4. Kukanganisa kunokonzerwa neSMT tin quality uye teknolojia: Nguva yekugara muchoto chetini yakareba kwazvo panguva yekuputika, izvo zvinoita kuti gomba remhangura rinyunguduke, izvo zvinokonzera kukanganisa. Novice vanobatana, maererano nenguva yekutonga, kutonga kwezvinhu hazvina kunyatsojeka , Pasi pekushisa kwepamusoro, pane kukanganisa pasi pezvinhu, izvo zvinoita kuti gomba remhangura rinyunguduke uye rikundike. Chaizvoizvo, ikozvino bhodhi fekitari inogona kuita inobhururuka kuongorora bvunzo yeiyo prototype, saka kana ndiro inoitwa 100% inobhururuka probe bvunzo, kudzivirira bhodhi kugamuchira ruoko kuti uwane matambudziko. Izvo zviri pamusoro apa kuongororwa kweiyo inobhururuka probe bvunzo yedare redunhu, ndinovimba kubatsira munhu wese.
