Zaka za zana la 21 ndi zaka zaukadaulo. Chifukwa ukadaulo umayamba kuthamanga pakapita nthawi. Kuphatikiza apo, ntchito za msonkhano wa PCB zimachita kufunikira komanso kofunikira mu chitukuko ichi.
M'malo mwake, zida ndi zida zamagetsi zimayamba kusintha. Kugwiritsa ntchito ma PCB m'njira yanu yovuta komanso yosavuta ndiyofunika. Chifukwa chake, pcba (msonkhano wamasitima ozungulira) ntchito ndi msana wa mafakitale amagetsi. Tiyeni tiwerenge ndi kufufuza zambiri za ntchito za PCBA.
Njira zitatu zazikulu za PCB
Kudzera muukadaulo wa hod (tht):
Panthawi imeneyi, wopanga
kutsogolera. Mu msonkhano uno wa PCB, amagwiritsa ntchito PCB yokhala ndi mabowo omata.
Chifukwa chake, ndizosavuta kusonkhanitsa zinthu zomwe zili ndi PCB popeza zotsogolera zimayikidwa m'mabowo omata.
Pamalo a Phiri Lamalo (SMT):
Njirayi imayamba mu 60s. Kuphatikiza apo, idapangidwanso m'ma 80.
Masiku ano, ntchito ya msonkhano ku PCB ili imagwiritsidwa ntchito kwambiri ndi opanga angapo a PCA.
Panthawi imeneyi, opanga amagetsi amaphatikiza magawo onse okhala ndi zitsulo zomwe amatha kuwugulitsa mofatsa ku PCB.
Ili ndi njira yokazinga bwino kwambiri. Kuphatikiza apo, njirayi imaperekanso kachulukidwe kambiri ndipo titha kukhala otetezeka mbali zonse za PCB.
Msonkhano wamagetsi:
Dzina linanso la msonkhano uno ndi msonkhano womanga bokosi. Kuphatikiza apo, njirayi imagwiritsa ntchito zinthu zotsatirazi:
• Loom
• Misonkhano yazingwe
• kukhazikika
• pulasitiki yopangidwa
• Zikondwerero zachikhalidwe.
PCBA Ntchito Titha Kupereka:
• Kupanga limodzi ndi msonkhano umodzi: Njira yothetsera yosinthira kuyambira poyambira zosowa zanu zonse.
• Ntchito zosiyanasiyana za PCB:
• Msonkhano wosinthika wa pamsonkhanowu: prototype, batch yaying'ono, kufalikira kwapamwamba - titha kuchita zonse.
• Magawo omwe akuwopseza: Tili ndi zaka zambiri zokumana nazo komanso zopangidwa ndi opanga magetsi ovomerezeka ndi ogulitsa, kotero nthawi zonse mumapeza zigawo zabwino. Magawo onse ndi abwino 100% oyesedwa musanagwiritse ntchito.
• Chitsimikizo chokwanira: Kuchokera pakuwunikira kwa AOI ndi X-ray kuyendera, timayendetsa bwino kwambiri komanso kuyesa zonse zogwirira ntchito ndi mtundu.
• Kuthamanga kwambiri, mtengo wotsika: Mudzazindikira kufunika kwa ntchito zathu zaulere monga varr dfm / dfa kuyerekeza ndi katswiri wopanga akatswiri.
• APHUNZITSIDWA AUTHEPERIQUISTIONE AWERENGER: Ndife oyenera kwambiri ndipo tikudzipereka pantchito yanu, ndikukulolani kuyamba ndi kapangidwe kotsimikizika ndikukupatsani mwayi wokwaniritsa zomwe zikuchitika.
