Ma electrons amatanthawuza zipangizo zamagetsi zomwe zimagwiritsidwa ntchito m'magalimoto, kuphatikizapo ma modules oyendetsa injini, machitidwe osangalatsa a chidziwitso, machitidwe otetezera, masensa, ndi zina zotero. Zidazi ziyenera kugwiritsa ntchito matabwa ozungulira (PCBA) kuti akwaniritse ntchito zawo.
PCBA, yomwe ili yoyenera zamagetsi zamagalimoto, imafunikira izi:
- Kudalirika kwakukulu:Malo ogwiritsira ntchito zamagetsi zamagetsi zamagalimoto ndizovuta, ndipo zovuta zachilengedwe monga kuthamanga kwambiri, kutentha kwambiri, ndi chinyezi chachikulu zimafunikira. Chifukwa chake, PCBA imafunikira kudalirika kwambiri ndipo imatha kuthamanga mokhazikika.
- Mphamvu yolimbana ndi kusokoneza:Galimotoyo ili ndi ma transmitters osiyanasiyana ndi olandila, monga wailesi, radar, GPS, etc. Izi zimakhala ndi kusokoneza kwakukulu, kotero PCBA imayenera kukana kusokoneza kumeneku.
- Kuchepetsa:Danga mkati mwa galimoto ndi laling'ono, kotero PCBA ayenera kukhala ndi makhalidwe a miniaturization, amene angathe kukwaniritsa chofunika dera ntchito mu malo ochepa.
- Kugwiritsa ntchito mphamvu zochepa:Zida zamagetsi zamagalimoto zimafunika kugwira ntchito pagalimoto kwa nthawi yayitali, chifukwa chake ndikofunikira kusunga mphamvu ndikuchepetsa kugwiritsa ntchito ndikusunga mphamvu.
- Kusamalira:Kukonza zida zamagetsi zamagetsi ziyenera kukhala zosavuta komanso zachangu, ndipo PCBA iyenera kukhala ndi mawonekedwe a disassembly yosavuta ndi kukonza.
Malingana ndi zofunikirazi, PCBA, yomwe ili yoyenera zida zamagetsi zamagetsi, iyenera kusankha kudalirika kwakukulu ndi zigawo zabwino za kutentha kwa kutentha, ndikutengera mapangidwe apadera ndi kupanga kupanga kuonetsetsa kuti PCBA ndi yodalirika. Pa nthawi yomweyo, m'pofunika kuganizira masanjidwe PCB ndi kukhathamiritsa mzere kuonetsetsa bata ndi odana-kusokoneza.
Nawa mitundu ina ya PCBA yomwe imagwiritsidwa ntchito kwambiri pamagetsi apagalimoto:
FR-4 Fluoro Zinthu Zofunika PCBA
Ndi muyezo dera bolodi zakuthupi. Ili ndi kukana bwino kwa dzimbiri, mwaukali komanso kutsekereza, ndipo imatha kupirira malo omwe amagwirira ntchito pamagalimoto wamba.
Kutentha kwambiri kwa PCBA
Oyenera malo otentha kwambiri muzinthu zamagetsi zamagalimoto. Mtundu uwu wa PCBA nthawi zambiri umagwiritsa ntchito polyimide ngati gawo lapansi, lomwe lili ndi kukana kutentha kwambiri.
Integrated circuit (IC) PBCA
Ndizoyenera zamagetsi zamagalimoto zomwe zili zoyenera kugwiritsa ntchito makina ophatikizika kwambiri. Ili ndi ntchito yabwino kwambiri ndipo ili ndi ubwino wothamanga kwambiri, kachulukidwe kakang'ono komanso kakang'ono.
Metal gawo lapansi PCBA
Ndizoyenera kumagetsi amagalimoto omwe amafunikira mphamvu zambiri komanso ntchito yochotsa kutentha. PCBA yotereyi imagwiritsa ntchito aluminiyamu ndi zitsulo zamkuwa monga zinthu zapansi panthaka, zomwe zimakhala ndi matenthedwe abwino komanso kutentha kwa kutentha.
PCBA
PCBA yopangidwira ntchito monga makina osangalatsa agalimoto, zojambulira zoyendetsa, makina oyenda, ndi zina zambiri.
Mitundu iyi ya PCBA ili ndi mawonekedwe osiyanasiyana komanso mawonekedwe ogwiritsira ntchito. Iwo akhoza kusankha abwino kwambiri PCBA chitsanzo malinga ndi zofunika galimoto zamagetsi.
