PCB bolodi kupanga tanthauzo:

Complete interconnect zigawo zamagetsi zosindikizidwa board board kapena PCB. Ili ndi ma circuits osakwatiwa komanso angapo. Mbale izi zimakwaniritsa kufunikira kwa makina amagetsi ndi ma circuits. Bokosi la PCB lili ndi gawo lotetezera pomwe pamakhala gawo lazinthu zoyipa. Zida zamagetsi zamagetsi zimayikidwa pazotetezera (gawo lapansi) la PCB ndipo yolumikizidwa ndi dera lothandizirana kudzera pachikondi ndi zomatira. Zitha kugwiritsidwanso ntchito ngati ma switchboard ovomerezeka.

Opanga akuyembekezeka kufalitsa zolakwika zilizonse zopanda pake mudongosolo lomwe lakonzedwa. Komabe, izi zikuchitika mosemphana ndi zina pamene mabungwe ambiri amapereka zopempha zawo za PCB kwa omwe amapereka kunja.

Type:

PCB imamanga kugwera m’mitundu itatu yayikulu:

Mbali imodzi: Ma PCBSwa amakhala ndi zida zopangira kutentha komanso zophatikizika zamkuwa zophatikizika. Zamagetsi zimalumikizidwa mbali imodzi ya gawo lapansi.

Mbali ziwiri: Mu PCB iyi, zida zina zambiri zitha kukhazikitsidwa pagawo kuposa PCB yokhayo.

Multilayer: Zigawo pa gawo lapansi zimalumikizidwa pobowoleza m’mabowo osanjikizika pamagetsi oyenera. Chiwerengero cha PCBS zama multilayer chimaposa ma PCBS amtundu umodzi komanso amagulu awiri. Zimapangitsa dongosolo la dera kukhala losavuta.

Palinso mitundu iwiri: ma circuits ophatikizidwa (amadziwikanso kuti ics kapena ma microchips) ndi ma hybrid circuits. Njira za IC ndizofanana ndi mitundu ina, koma ndimaseketi ambiri omwe amakhala pamwamba pa tchipisi tating’ono tating’onoting’ono. Kusiyana kokha m’mabwalo a haibridi ndikuti zigawo zake zimakula pamtunda m’malo moikidwa zomatira.

Zopangira:

Pa bolodi la PCB, gawo lamagetsi limakhala pamwamba. Palinso njira zosiyanasiyana, monga:

Kudzera luso dzenje:

Kwa zaka zambiri, ukadaulo wapabowo wakhala ukugwiritsidwa ntchito popanga pafupifupi ma board board onse (PCBS). Gawo lowoloka limakonzedwa ndi ma lead awiri ofananira. Kuti mukhale ndi mphamvu zama makina, zotsogola ndizopindika pa Angle ya 90 degree ndikugulitsidwa kwina. Kuyika-kubowo kumakhala kodalirika kwambiri chifukwa kumapereka kulumikizana kwamphamvu kwamakina; Komabe, kuboola kowonjezeraku kunapangitsa matabwa kukhala okwera mtengo kwambiri kupanga.

Zimaonekera luso phiri:

SMT ndiyotsika poyerekeza ndi mnzake wapabowo. Izi ndichifukwa choti chinthu cha SMT chimakhala ndi mayendedwe ang’onoang’ono kapena sichitsogolera konse. Ndi kotala mpaka kotala kupyola mu bowo. Ma PCBS okhala ndi zida zapamwamba (SMD) safuna kuboola kochuluka, ndipo izi ndizocheperako, kulola kuchuluka kwa madera m’mabwalo ang’onoang’ono.

Kupyolera muzochita zabwino zokha, ndalama zogwirira ntchito zimachepetsedwa ndipo zokolola zimayenda bwino kwambiri.

Kupanga:

Opanga ma board a PCB amagwiritsa ntchito zojambula zothandizidwa ndi makompyuta (CAD) kuti apange masekondi oyenda. Ntchito zapadera zimaperekedwa kuzinthu zina. Bungwe loyang’anira liyenera kugwira ntchito yomwe limasankha. Danga pakati pa dera ndi njira yodutsira ndilopapatiza. Nthawi zambiri imakhala mainchesi 0.04 (1.0 mm) kapena ochepera.

Iwonetsanso kutsogolera kapena kukhudza chinthu pafupi ndi dzenje, ndipo cholembedwachi chidzasandulika malangizo a pobowola laputopu ya CNC kapena ukadaulo wopanga womwe umagwiritsidwa ntchito pamapuloteni otsekemera.

Sindikizani chithunzi cholakwika kapena maski kukula kwake papepala loyera, mwachitsanzo mutangowonetsa zitsanzo za dera. Ngati chithunzicho sichili bwino, dera lomwe silingakhale chidutswa cha dera lidzakhazikitsidwa lakuda ndipo mawonekedwe adzayesedwe momveka bwino.
