Kana mukuruX-ray muchinaDambudziko rekushongedza chairo harigone kuongororwa, unogona kushandisa inki tsvuku uye chikamu kuti uwane dambudziko?Asi kana kudziyisa kanareflow ovenwelding, PCBA kugadzirisa mushure mebvunzo uye yapasa, wobva waita inki tsvuku uye chidimbu bvunzo zvichabatsira?Kana mutengi akakumbira kutora bhodhi rakanaka kuti aite zvakare, tinogona kuona here kuti idambudziko rekuita?
Q1: Kazhinji, kana welding yenhema yezvikamu zvisiri zveBGA zvinogona kuonekwa neziso rakashama, nokuti solder yenhema inoputika ichaita hurema huri pachena, hunogona kuonekwa nyore nyore pasi pemamiriro ekugadzirisa.
Kubva pane tsananguro yemubvunzo, tinogona kufungidzira kuti mubvunzi aifanira kunge akasangana neabnormal quality yeBGA kana IC component welding.3DX-Ray scanning imaging inogona kushandiswa kuona welding yenhema muSMT SMT processing.Iyi zvakare ndiyo huru inoshanda midziyo uye nzira yekuongorora welding yeBGA/IC zvikamu, izvo pasina mubvunzo zvinosimbiswa neruzhinji rwevagadziri vePCBA.
Asi kana bhora pacharo rakatyoka kana kunaka kwebhora kusiri kwemaitiro, zvinogona kuongororwa pachishandiswa inki dzvuku uye test test, nekuti inomaly iyi haionekwe neX-ray.
Q2: Kana dambudziko reBGA risina kusimbiswa, solder paste iri reflow oven welding zvakare, iyo inogona kuvhara dambudziko rechokwadi.Mukuwedzera, rimwe dambudziko nderekuti kunobva mapoinzi emhando ichaparadzwa, saka hazvina kuvimbiswa kuti isu tinogona kutarisa chaiyo yakaipa mapoinzi.
BGA kukundikana kunofanira kutanga kubvisa matambudziko emhando yerata pachayo, uye mamwe anofanirwa kusimbiswa sematambudziko ewelding interface kana tembiricha kugadzirisa.Manongedzo akasiyana anoburitsa akasiyana mapoinzi asina kujairika.Uye yakawanda yakaipa BGA welding haisati iri dambudziko rekuita.
Kana isu tichinyatsoda kuongorora, zvinokurudzirwa kutora chidimbu chezvigadzirwa zvakakanganisika kuti zvionekwe kwese-kutenderera, kuona nemhando yeanomalies yeimwe neimwe link, kuratidza kana isu tichinyatso sangana nerudzi urwu rwekukanganisa, tozogadzirisa zvinoenderana.
