Zogulitsa
Telecom Cellphone main board kusonkhanitsa kupanga
Iyi ndi pulojekiti ya PCB yopanga mafoni am'manja.Zamagetsi ogula, kuyambira zomvera mpaka zovala, masewera kapena zenizeni zenizeni, zonse zikulumikizana kwambiri.Dziko la digito lomwe tikukhalamo limafuna kulumikizana kwapamwamba komanso zida zamakono komanso luso lapamwamba, ngakhale pazinthu zosavuta, kupatsa mphamvu ogwiritsa ntchito padziko lonse lapansi. engineering, kapangidwe ndi prototyping.

Ndondomeko ya Msonkhano wa SMT
1. Malo (kuchiritsa)
Ntchito yake ndi kusungunula guluu chigamba kuti zigawo pamwamba phiri ndi bolodi PCB zolimba zomangira pamodzi.
Zida zomwe zimagwiritsidwa ntchito ndi uvuni wochiritsira, womwe uli kuseri kwa makina oyika mu mzere wa SMT.
2. Kugulitsanso
Ntchito yake ndi kusungunula phala solder, kuti pamwamba phiri zigawo zikuluzikulu ndi bolodi PCB ndi zolimba omangika pamodzi.Zida zomwe zinagwiritsidwa ntchito zinali uvuni wa reflow, womwe uli kuseri kwa mapepala.
Mounter pamzere wopanga wa SMT.
3. Kuyeretsa msonkhano wa SMT
Zomwe zimachita ndikuchotsa zotsalira za solder monga ux
PCB yosonkhanitsidwa ndi yovulaza thupi la munthu.Zida zomwe zimagwiritsidwa ntchito ndi makina ochapira, malo angakhale
Zosakhazikika, zitha kukhala zapaintaneti kapena zopanda intaneti.
4. Kuyendera msonkhano wa SMT
Ntchito yake ndi kufufuza khalidwe kuwotcherera ndi khalidwe msonkhano
The anasonkhana PCB board.
Zida zomwe zimagwiritsidwa ntchito zikuphatikiza magalasi okulirapo, maikulosikopu, tester in-circuit (ICT), singano tester, automatic Optical inspection (AOI), X-RAY inspector system, functional tester, etc.
5. Kukonzanso msonkhano wa SMT
Ntchito yake ndikukonzanso gulu la PCB lomwe lalephera
Kulakwitsa.Zida zomwe zimagwiritsidwa ntchito ndi soldering iron, rework station, etc.
paliponse pamzere wopanga.Monga mukudziwira, pali zinthu zing'onozing'ono panthawi yopanga, kotero kukonzanso manja ndi njira yabwino kwambiri.
6. Kuyika kwa msonkhano wa SMT
PCBMay imapereka kusonkhanitsa, kuyika makonda, kulemba zilembo, kupanga zipinda zoyeretsa, kasamalidwe ka njira zotsekera ndi njira zina kuti apereke yankho lathunthu pazosowa za kampani yanu.
Pogwiritsa ntchito makina opangira okha kuti asonkhanitse, phukusi ndi kutsimikizira malonda athu, titha kupatsa makasitomala athu njira yodalirika komanso yabwino yopangira.
Wothandizira zamagetsi pagalimoto zamagalimoto, timagwira ntchito zingapo:
> Kamera yamagalimoto yamagalimoto
> Kutentha & chinyezi masensa
> Nyali yakutsogolo
> Kuyatsa kwanzeru
> Ma module amphamvu
> Zowongolera zitseko & zogwirira zitseko
> Ma module owongolera thupi
> Kasamalidwe ka mphamvu
Chachitatu, mitengo ndi yosiyana chifukwa cha zovuta komanso kachulukidwe.
PCB idzakhala yosiyana mtengo ngakhale zipangizo ndi ndondomeko ndi zofanana, koma ndi zovuta zosiyana ndi kachulukidwe.Mwachitsanzo, ngati pali mabowo 1000 pama board onse ozungulira, dzenje la bolodi limodzi ndi lalikulu kuposa 0.6mm ndipo m'mimba mwake la bolodi lina ndi lochepera 0.6mm, zomwe zimapanga ndalama zoboola zosiyanasiyana.Ngati matabwa awiri dera ali ofanana zopempha zina, koma mzere m'lifupi ndi osiyana komanso zimabweretsa mtengo osiyana, monga bolodi m'lifupi ndi lalikulu kuposa 0.2mm, pamene winayo ndi zosakwana 0.2mm.Chifukwa matabwa m'lifupi osakwana 0.2mm ali ndi chiwopsezo chachikulu, zomwe zikutanthauza kuti mtengo wopangira ndi wokwera kuposa wanthawi zonse.
Chachinayi, mitengo ndi yosiyana chifukwa cha zofunika zosiyanasiyana za makasitomala.
Zofuna zamakasitomala zidzakhudza mwachindunji mlingo wosakhala wolakwika pakupanga.Monga gulu limodzi logwirizana ndi IPC-A-600E class1 limafuna 98% kukhoza, pamene mgwirizano wa kalasi3 umangofunika kukhala ndi 90% yokha yopambana, zomwe zimapangitsa kuti fakitale iwonongeke ndipo pamapeto pake imabweretsa kusintha kwamitengo yazinthu.
