Tsanangura iyo Flying Bvunzo ye circuit board zvakadzama

Nheyo yedunhu redhiza inobhururuka pini bvunzo iri nyore kwazvo. Izvo zvinongoda ma probes maviri kufambisa x, y uye Z kuyedza iwo maviri magumo edunhu rega rimwe nerimwe, saka hapana chikonzero chekugadzira imwe inodhura ficha. Nekudaro, nekuda kwekuyedzwa kwekupedzisira, iyo yekuyera kumhanya inononoka, ingangoita gumi ~ makumi mana mapoinzi / sec, saka inokodzera masampuli uye mashoma mashoma kugadzirwa; Panyaya yehuwandu hweyedzo, kubhururuka kwetsono bvunzo kunogona kuiswa kune akakwirira kwazvo mapodhi, akadai seMMM.

Nhungamiro yekubhururuka tsono tester: ndeye kushandisa mana masekesi kuitisa yakakwira-voltage kuputira uye yakaderera kuramba conduction bvunzo (edza iyo yakavhurika dunhu uye ipfupi dunhu remutsara) kune wedunhu bhodhi, sekureba sekuyedza gwaro rakaumbwa neiyo mutengi wepakutanga uye neyedu enjiniya dhizaini.

Mushure mekuyedzwa, pane zvikonzero zvina zvedunhu pfupi uye rakavhurika redunhu.

1. Faira revatengi: muyedzo unogona chete kuenzanisa, kwete kuongorora

2. Kugadzirwa kwemutsara kugadzirwa: warpage, solder kuramba uye asiri-akajairwa mavara ePBBP bhodhi

3. Maitiro ekushandurwa kwedata: kambani yedu inotora yeinjiniya dhizaini bvunzo, uye imwe data (kuburikidza) yeinjiniya dhizaini yakasiyiwa

4. Zvishandiso zvinhu: software uye Hardware matambudziko

Patakatambira bhodhi rakapasa bvunzo yedu uye tikariisa, takasangana nekuvharika-kwegomba. Handizive chakakonzereswa nei. Isu takakanganisa kufunga kuti kwaive kuyedza kwedu, asi zvakare kwakatumirwa. Muchokwadi, kune zvikonzero zvakawanda zvekuvharika-kwegomba.

Pane zvikonzero zvina zveizvi:

1. Kukanganisa kunokonzerwa nekuchera: iyo ndiro inogadzirwa ne epoxy resin girazi fiber. Mushure mekuchera, pane guruva rakasara mugomba, risina kucheneswa, uye mhangura haigone kuiswa mushure mekurapa. Kazhinji, isu tichazviedza mune inobhururuka tsono bvunzo yekubatanidza.

2. Kukanganisa kunokonzerwa nekuiswa kwemhangura: iyo nguva yekuisa mhangura ipfupi, gomba mhangura haina kuzara, uye gomba mhangura harizare kana tini yaiswa, zvichikonzera mamiriro asina kunaka. (mune chemakemikari dhodhi dhipoziti, pane dambudziko mune imwechete yekubatanidza glue slag kubviswa, alkaline mafuta kubvisa, micro etching, activation, kumhanyisa uye kuisirwa mhangura, kukura kusingaperi, kuwedzeredza kugadzirwa, uye mhinduro yakasara mugomba haina kushambidzwa yakachena. Hakananga maficha akaongororwa zvakadzama)

3. Circuit board vias inoda yakawandisa yazvino uye haina kuziviswa pachine nguva nezve kudiwa kwekukuya gomba mhangura. Dambudziko iri rinowanzoitika kana razvino rakanyanya kukura kuti rinyungudze gomba remhangura mushure memagetsi. Ikozvino kukosha kweyekufungidzira hakuenzane neyazvino, zvichikonzera kunyungudika kwakananga kwegomba remhangura mushure memagetsi, zvichikonzera kusaenderera kweiyo nzira, iyo inofungidzirwa zvisirizvo kuti bvunzo haina kuitwa.

4. Kukanganisa kunokonzerwa nehunhu uye tekinoroji yeSMT tini: iyo yekugara kwenguva refu muvira remoto panguva yekutungidza inotungamira mukunyungudika kwegomba mhangura, zvinotungamira mukuremara. Vabatsiri veNovice havana kunyatsojeka mukutonga izvo zvinhu maererano nenguva yekudzora, uye vanokanganisa pasi pezvinhu patembiricha yakakwira, izvo zvinotungamira mukundikana kwegomba mhangura yakanyungudika. Iyo yazvino ndiro fekitori inogona chaizvo kuita inobhururuka tsono bvunzo pane iwo masampuli, saka kana iyo ndiro inogadzira ichiri kuwana 100% inobhururuka tsono bvunzo kudzivirira matambudziko anowanikwa mumaoko eplate.

Mhedziso: kuburikidza nekudzidza, isu tichazoziva zvakawanda nezve zvidiki diki zvekubhururuka nesero bvunzo uye kuziva kwekuenda mune redu basa.
