Maitiro ekuvandudza goho rekutengesa kweiyo yakanaka-pitch CSP uye zvimwe zvikamu?Ndezvipi zvakanakira uye zvakaipira zvemhando dzewelding senge hot air welding uye IR welding?Kuwedzera kune wave soldering, pane imwe solder process yePTH zvikamu?Nzira yekusarudza sei tembiricha yepamusoro uye yakaderera tembiricha solder paste?
Welding inzira yakakosha mukusangana kwemabhodhi emagetsi.Kana iyo isinganyatsogadziriswi, kwete kungokundikana kwekanguva kwakawanda kuchaitika, asiwo hupenyu hwemajoini e solder huchabatwa zvakananga.
Reflow soldering tekinoroji haisi nyowani mumunda wekugadzira zvemagetsi.Izvo zvikamu pamabhodhi akasiyana ePCBA anoshandiswa mumafoni edu anotengeswa kubhodhi redunhu kuburikidza nemaitiro aya.SMT reflow soldering inoumbwa nekunyungudusa pre-yakaiswa solder pamusoro Solder majoini, solder nzira isingawedzeri mamwe solder panguva solder process.Kuburikidza nemhepo yekudziya mukati memidziyo, mhepo kana nitrogen inopisa kusvika pakakwirira zvakakwana tembiricha uye yobva yapeperetswa kubhodhi redunhu uko zvikamu zvakanamirwa, kuitira kuti zvikamu zviviri Iyo solder paste solder padivi inonyungudutswa uye inosungirirwa motherboard.Kubatsira kweichi chiitiko ndechekuti tembiricha iri nyore kudzora, oxidation inogona kudziviswa panguva yekushambadzira, uye mutengo wekugadzira zvakare nyore kudzora.
Reflow soldering yave nzira huru yeSMT.Zvizhinji zvezvikamu pamabhodhi edu e-smartphone zvinotengeswa kubhodhi redunhu kuburikidza nemaitiro aya.Kuita kwemuviri pasi pekuyerera kwemhepo kuti uwane SMD welding;chikonzero nei ichinzi "reflow soldering" imhaka yekuti gasi rinotenderera mumushini we welding kuburitsa tembiricha yakanyanya kuzadzisa chinangwa chewelding.
Reflow soldering midziyo ndiyo yakakosha midziyo mumusangano weSMT.Iyo solder yakabatana mhando yePCBA solder inoenderana zvachose nekuita kweiyo reflow solder michina uye kuseta kweiyo tembiricha curve.
Iyo reflow soldering tekinoroji yakasangana nemhando dzakasiyana dzekusimudzira, senge plate radiation kudziyisa, quartz infrared chubhu kudziyisa, infrared inopisa mhepo kupisa, kumanikidzwa kupisa kwemhepo kupisa, kumanikidza kupisa kwemhepo kupisa pamwe nekuchengetedzwa kwenitrogen, nezvimwe.
Kuvandudzwa kwezvinodiwa zvechiito chekutonhora kwereflow soldering zvakare kunosimudzira kuvandudzwa kwenzvimbo yekutonhodza yereflow soldering michina.Nzvimbo yekutonhodza inotonhodzwa pachigadziko tembiricha, mhepo-yakanyoroveswa kune inotonhorera-inotonhorera sisitimu yakagadzirirwa kuchinjika kune lead-isina soldering.
Nekuda kwekuvandudzwa kwemaitiro ekugadzira, iyo reflow soldering midziyo ine yakakwira zvinodiwa pakurongeka kwekudzora tembiricha, kufanana kwetembiricha munzvimbo yekushisa, uye kumhanya kwekutapurirana.Kubva munzvimbo nhatu dzekutanga tembiricha, masisitimu emagetsi akasiyana akadai senzvimbo shanu dzetembiricha, nzvimbo nhanhatu dzetembiricha, nzvimbo nomwe dzetembiricha, nzvimbo sere dzetembiricha, uye gumi tembiricha nzvimbo dzakagadzirwa.
Nekuda kwekuenderera mberi miniaturization yezvigadzirwa zvemagetsi, chip zvikamu zvakaonekwa, uye yechinyakare welding nzira haichakwanise kuzadzisa zvinodiwa.Chekutanga pane zvese, iyo reflow soldering process inoshandiswa mukusangana kwemahybrid akasanganiswa maseketi.Zvizhinji zvezvikamu zvakaunganidzwa uye zvakasungwa chip capacitors, chip inductors, mount transistors uye diode.Nekuvandudzwa kwese tekinoroji yeSMT ichiwedzera uye yakanyanya kukwana, akasiyana siyana chip components (SMC) uye gomo zvishandiso (SMD) anooneka, uye reflow soldering process tekinoroji nemidziyo sechikamu cheiyo inokwirisa tekinoroji yakagadziridzwawo saizvozvo. uye kushandiswa kwayo kuri kuramba kuchiwedzera.Yakaiswa mune dzinenge dzese zvigadzirwa zvemagetsi minda, uye reflow soldering tekinoroji yakapindawo anotevera matanho ebudiriro akatenderedza kuvandudzwa kwemidziyo.
