Pankhani yamagetsi, matabwa osindikizira (PCBs) ndi gawo lofunikira pakupanga ndi kupanga.Mwachidule, PCB ndi bolodi lopangidwa ndi zinthu zopanda ma conductive zomwe zimakhala ndi njira zoyendetsera kapena zolumikizira zomwe zimalumikiza zida zosiyanasiyana zamagetsi monga resistors, capacitors ndi transistors.
Mapangidwe a PCB amaphatikizapo kupanga masanjidwe a maulumikizidwe ndi zigawo pa bolodi yozungulira, zomwe ndizofunikira kuti zitsimikizire kuti chinthucho chimagwira ntchito moyenera komanso chodalirika.Pamene teknoloji ikupita patsogolo, kufunikira kwa mapangidwe abwino ndi apamwamba a PCB akupitiriza kuwonjezeka.
Ubwino wa PCB Design
Mapangidwe a PCB amapereka maubwino angapo kuposa mawaya achikhalidwe komanso njira zomangira zamagetsi zamagetsi.Izi zikuphatikizapo:
1. Kupulumutsa malo: Ma PCB amachotsa kufunikira kwa mawaya akuluakulu, kotero kuti zida zazing'ono, zophatikizika kwambiri zitha kupangidwa.
2. Kukhalitsa: Chifukwa ma PCB amapangidwa ndi zinthu zolimba ndipo ali ndi makina olumikizana mwamphamvu, amatha kupirira kutentha kwambiri, chinyezi, ndi kugwedezeka.
3. Kusasinthasintha: Ma PCB amapangidwa ndikusonkhanitsidwa pansi pa malangizo okhwima owongolera, motero amapereka magwiridwe antchito osasinthika.
4. Kusinthasintha: Mapangidwe a PCB akhoza kusinthidwa kuti akwaniritse zofunikira zenizeni, kuphatikizapo kukula, mawonekedwe ndi chiwerengero cha zigawo.
5. Zosawononga ndalama: Ma PCB amachepetsa mtengo wopangira zida zamagetsi chifukwa zimathamanga komanso zosavuta kupanga kusiyana ndi njira zachikhalidwe zamawaya.
Kodi PCB imapanga chiyani?
Mapangidwe a PCB amaphatikizapo magawo angapo ndipo njirayo imatha kusiyanasiyana kutengera zovuta za polojekitiyo.Komabe, njira zina zomwe zimakhudzidwa ndi izi:
1. Kujambula kwadongosolo: Izi zikuphatikizapo kujambula chithunzi cha dera lamagetsi, kuphatikizapo malumikizidwe ndi makhalidwe a chigawo chilichonse.
2. Mapangidwe a PCB: Apa ndi pamene mapangidwe amasamutsidwa ku bolodi lakuthupi kapena "chinsalu" ndipo zigawo zake ndi zizindikiro zimayikidwa bwino.
3. Kupanga kwa PCB: Kukonzekera kukamalizidwa, gulu lozungulira lidzadutsa njira zingapo zamakina kuphatikizapo etching, kubowola, soldering ndi kuyesa.
4. Msonkhano: Apa ndi pamene zida zamagetsi zimayikidwa pamwamba pa bolodi ndi ndondomeko yotchedwa Surface Mount Technology (SMT).
5. Kuyesa ndi Kutsimikizira: Akasonkhanitsidwa, gululo limayesedwa ndi kutsimikiziridwa kosiyanasiyana kuti zitsimikizire kuti zolumikizira zonse ndi zolondola ndipo kapangidwe kake kakugwira ntchito moyenera.
Pomaliza
Mapangidwe a PCB ndi gawo lofunikira pakupanga zida zamagetsi.Ndi ubwino wawo ambiri, n'zosadabwitsa kuti PCBs ndi kusankha otchuka pakati pa akatswiri zamagetsi ndi opanga padziko lonse.Pomwe ukadaulo ukupitilirabe kusinthika, mapangidwe a PCB adzakhalabe luso lofunikira kwa akatswiri pantchitoyo.Ndi maphunziro oyenera ndi chuma, aliyense akhoza kukhala waluso PCB mlengi amene akhoza kupanga apamwamba mankhwala amagetsi malinga ndi zosowa ndi zofunika.
