Wopanga PCB Wopikisana

SMT ndiye chidule cha Surface Mounted Technology, Tekinoloje yotchuka kwambiri komanso njira zamabizinesi apakompyuta.Electronic circuit Surface Mount Technology (SMT) imatchedwa Surface Mount kapena Surface Mount Technology.Ndi mtundu waukadaulo wamtundu wa Circuit Assembly womwe umayika zida zotsogola zopanda lead kapena zazifupi (SMC/SMD mu Chitchaina) pamwamba pa Printed Circuit Board (PCB) kapena gawo lina laling'ono, kenako amawotcherera ndikuphatikizana pogwiritsa ntchito kuwotcherera kapena kuwotcherera kuwotcherera dip.

Nthawi zambiri, zinthu zamagetsi zomwe timagwiritsa ntchito zimapangidwa ndi PCB kuphatikiza ma capacitor osiyanasiyana, zopinga ndi zida zina zamagetsi molingana ndi chithunzi chozungulira, kotero zida zamagetsi zamitundu yonse zimafunikira ukadaulo wosiyanasiyana wa SMT chip processing.

Zinthu zoyambira za SMT zimaphatikizapo: kusindikiza pazenera (kapena kugawa), kukwera (kuchiritsa), kuwotchereranso, kuyeretsa, kuyesa, kukonza.

1. Screen yosindikiza: Ntchito yosindikiza chophimba ndi kutayikira solder phala kapena chigamba zomatira pa PCB a solder PAD kukonzekera kuwotcherera zigawo zikuluzikulu.Zida zomwe zimagwiritsidwa ntchito ndi makina osindikizira pazenera (makina osindikizira pazenera), omwe ali kumapeto kwa mzere wopanga SMT.

2. Glue kupopera mbewu mankhwalawa: Imagwetsa guluu ku malo okhazikika a bolodi la PCB, ndipo ntchito yake yayikulu ndikukonza zigawo za bolodi la PCB.Zida zomwe zimagwiritsidwa ntchito ndi makina operekera, omwe ali kumapeto kwa mzere wopanga SMT kapena kuseri kwa zida zoyesera.

3. Phiri: Ntchito yake ndikuyika zigawo za msonkhano pamwamba molondola pa malo okhazikika a PCB.Zida zomwe zimagwiritsidwa ntchito ndi makina oyika a SMT, omwe ali kuseri kwa makina osindikizira pazenera mu mzere wopanga wa SMT.

4. Kuchiritsa: Ntchito yake ndi kusungunula zomatira za SMT kuti zigawo za msonkhano wa pamwamba ndi bolodi la PCB zigwirizane molimba.Zida zomwe zimagwiritsidwa ntchito ndikuchiritsa ng'anjo, yomwe ili kumbuyo kwa mzere wopanga wa SMT SMT.

5. Reflow kuwotcherera: ntchito reflow kuwotcherera ndi kusungunula solder phala, kuti zigawo pamwamba msonkhano ndi PCB bolodi mwamphamvu n'kudziphatika pamodzi.Zida zomwe zimagwiritsidwa ntchito ndi ng'anjo yowotcherera, yomwe ili mumzere wopanga ma SMT kuseri kwa makina oyika a SMT.

6. Kuyeretsa: Ntchitoyi ndikuchotsa zotsalira zowotcherera monga flux pa PCB yosonkhanitsidwa yomwe imakhala yovulaza thupi la munthu.Zida zomwe zimagwiritsidwa ntchito ndi makina otsuka, malowo sangathe kukhazikitsidwa, akhoza kukhala pa intaneti, kapena ayi.

7. Kuzindikira: Amagwiritsidwa ntchito kuti azindikire mtundu wa kuwotcherera ndi khalidwe la msonkhano wa PCB yomwe inasonkhana.Zida zomwe zimagwiritsidwa ntchito zikuphatikizapo galasi lokulitsa, maikulosikopu, chida choyezera pa intaneti (ICT), chida choyesera singano chowulukira, kuyezetsa maso (AOI), makina oyesera ma X-ray, chida choyezera ntchito, ndi zina zotero. Malowa akhoza kukhazikitsidwa moyenerera gawo la mzere wopanga molingana ndi zofunikira pakuwunika.

8.Kukonza: imagwiritsidwa ntchito kukonzanso PCB yomwe yadziwika ndi zolakwika.Zida zomwe zimagwiritsidwa ntchito ndizitsulo zopangira zitsulo, kukonza malo ogwirira ntchito, ndi zina zotero. Kukonzekera kuli paliponse pamzere wopangira.
