Kodi Malangizo Pakukonzanso Magetsi Ndi Chiyani?

1. Rework rework maziko: rework rework alibe zikalata kapangidwe ndi malamulo, osavomerezedwa malinga ndi zofunikira, palibe odzipereka rework ndondomeko ndondomeko protocol.

2. Chiwerengero cha rework chololedwa kwa olowa aliyense solder: rework amaloledwa kwa zosalongosoka solder olowa, ndipo chiwerengero cha rework aliyense olowa solder si upambana katatu, mwinamwake solder mbali yawonongeka.

3. Kugwiritsiridwa ntchito kwa zigawo zochotsedwa: zigawo zochotsedwa mwalamulo siziyenera kugwiritsidwanso ntchito, ngati mukufunikira kugwiritsa ntchito, ziyenera kukhala zogwirizana ndi zinthu zoyambirira zamagetsi zamagulu ndi ndondomeko yowunikira ntchito, kukwaniritsa zofunikira musanalole kuyika.

4. Chiwerengero cha desoldering pa padi aliyense: aliyense wosindikizidwa pad ayenera kukhala desoldering ntchito (ndiko kuti, kungolola mmodzi m'malo zigawo zikuluzikulu), woyenerera solder olowa intermetallic pawiri (IMC) makulidwe a 1.5 kuti 3.5µm, makulidwe adzakula Pambuyo pa kusungunula, ngakhale mpaka 50µm, cholumikizira cha solder chimakhala chosalimba, mphamvu yowotcherera imachepa, pali zoopsa zodalirika pansi pamikhalidwe yogwedezeka;ndi remelting IMC amafuna kutentha kwambiri, apo ayi sizotheka kuchotsa IMC.Chosanjikiza chamkuwa chomwe chimatuluka pobowo ndi chocheperako kwambiri, ndipo padyo imatha kusweka kuchokera pano itatha kusungunuka;ndi kuwonjezereka kwa kutentha kwa Z-axis, kusanjika kwa mkuwa kumasokonekera, ndipo pad imachotsedwa chifukwa cha kutsekeka kwa cholumikizira cha lead-tin solder.Mlandu wopanda kutsogolera udzakoka pad yonse: PCB chifukwa cha utomoni wagalasi ndi utomoni wa epoxy wokhala ndi nthunzi wamadzi, pambuyo pa kutentha kwa delamination: kuwotcherera angapo, padiyo ndiyosavuta kumangirira, ndi kupatukana kwa gawo lapansi.

5. pamwamba phiri ndi osakaniza unsembe PCBA msonkhano pambuyo kuwotcherera kugwada ndi kupotoza zofunika: pamwamba phiri ndi osakaniza unsembe PCBA msonkhano pambuyo kuwotcherera kugwada ndi kupotoza zosakwana 0,75% ya zofunika.

6. Chiwerengero chonse cha kukonza msonkhano wa PCB: chiwerengero chonse cha kukonzanso kwa msonkhano wa PCB ndi malire asanu ndi limodzi, kukonzanso kwakukulu ndi kusinthidwa kumakhudza kudalirika.
