Nzira yekuziva sei zvisingaoneki kukanganisa kwePCBA zvakajeka?
X-RAY Kuongorora Maitiro
1. BGA solder majoini haana offset:
Kutonga kwemitemo: inogamuchirwa kana iyo yakagadziriswa iri pasi pehafu yedenderedzwa ye solder pad; Kana iyo yekubvisa yakakura kupfuura kana kuenzana nehafu yedenderedzwa repadhi rekutengesa, inorambwa.
2. BGA solder majoini haana pfupi redunhu:
Maitiro ekutonga: Kana pasina tin kuwirirana pakati pezvibatanidzwa zvekutengesa, zvinogamuchirwa; Kana pane solder yakabatana pakati pemajoini ekutengesa, inofanira kurambwa.
3. BGA solder majoini pasina voids:
Maitiro ekutonga: Nzvimbo isina chinhu isingasviki 20% yenzvimbo yese yejoint solder inogamuchirwa; Kana nzvimbo isina chinhu yakakura kupfuura kana yakaenzana ne20% yenzvimbo yese yejoint solder, inorambwa.
4. Hapana kushomeka kwetin muBGA solder joints:
Kutonga kwemaitiro: Gamuchira kana mabhora ese erata achiratidza hukuru hwakazara, yunifomu uye hunoenderana; Kana saizi yebhora rerata iri diki zvakanyanya kana ichienzaniswa nemamwe mabhora erata akaripoteredza, inofanira kurambwa.
5. Chiyero chekuongorora chepasi pedhi E-PAD yeQFP/QFN kirasi machipisi ezvimwe zvigadzirwa ndezvokuti nzvimbo yemarata inofanira kuva yakakura kupfuura 60% yenzvimbo yese (magridi mana akasanganiswa anoratidza kusungwa kwakanaka), uye sampling ratio. iri 20%.
1. Chinangwa chekuedza: mabhodhi ePCBA ane BGA / LGA uye pasi pedhi zvikamu;
2. Kuedza kakawanda:
① Mushure meshanduko, vashandi vehunyanzvi vanosimbisa kana yekutanga solder paste board uye BGA pamusoro pegomo ine chero kukanganisa, uye voenderera mberi nekupfuura nemukamuri mushure mekusimbisa kuti hapana matambudziko;
② Vashandi vehunyanzvi vanosimbisa kana paine nyaya neBGA solder yekutanga solder paste board mushure mekupfuura nemukamuri, vozoisa mukugadzira kana pasina matambudziko;
③ Panguva yekugadzirwa kwakajairwa, vashandi vakasarudzwa vane basa rekuyedza, uye kana mirairo ye ≤ 100pcs, 100% kuongororwa zvizere; 101-1000pcs kuti sampuli nokuda 30%, mirairo yakakura kupfuura 1001pcs kuti sampled nokuda 20%;
④ Munguva yeyakajairwa kugadzirwa, IPQC inoitisa sampling bvunzo pazvimedu zvihombe zviviri paawa;
⑤ Zvigadzirwa zvinofanirwa kuve 100% zvakayedzwa zvizere uye mafoto anofanira kuchengetwa 100%.
3. Kana pane kukanganisa, mapikicha anofanira kuchengetwa, uye iyo BOM model, barcode serial nhamba uye miedzo yemigumisiro yechigadzirwa chakaedzwa inofanira kunyorwa mu X-Ray Test Record Form. Wedzera mapikicha ekushongedza eQFP uye QFN yekumisa pads, uye chengetedza zana remifananidzo.
4. Kana paine chero kukanganisa panguva yekuedzwa, ivo vanofanirwa kuudzwa nekukurumidza kune mukuru uye process engineer yekusimbisa.
Industrial X-ray Intelligent Inspection Nyanzvi
Iyo sisitimu yeX-RAY michina inonyanya kuve nezvikamu zvinomwe: micro inotarisa X-ray sosi, yekufungidzira unit, komputa mufananidzo wekugadzirisa system, mechanika system, magetsi ekudzora system, kuchengetedza kuchengetedza uye yambiro system. Inosanganisa kuyedza kusingaparadze, tekinoroji yekombuta, kutora mifananidzo & kugadzirisa tekinoroji uye tekinoroji yekuparadzira tekinoroji, inofukidza mana makuru ehunyanzvi minda yeoptical, mechanic, yemagetsi uye yedhijitari mifananidzo yekugadzirisa. Kuburikidza nekuyamwisa misiyano yeX-rays nezvinhu zvakasiyana, chimiro chemukati chechinhu chinofananidzwa uye kutariswa kwekuremara kwemukati kunoitwa. Iyo yekuona mufananidzo wechigadzirwa inogona kucherechedzwa munguva chaiyo kuona kana paine hurema, hurema mhando uye indasitiri chiyero mazinga mukati mechigadzirwa. Panguva imwecheteyo, kombiyuta yekugadzirisa mifananidzo inoshandiswa kuchengetedza nekugadzirisa mifananidzo kuti ivandudze kujeka kwemifananidzo uye kuve nechokwadi chechokwadi chekuongorora. Inogona kuyera mabubble otomatiki pazvikamu zvemagetsi zvakarongedzwa seBGA neQFN, uye inotsigira zviyero zvejometri senge chinhambwe, kona, dhayamita, uye polygon. Inogona kuwana nyore kuona-mapoinzi ekumisikidza, ichibvumira zvigadzirwa kubva mufekitori zviine zero hurema.
