Tiyeni tione pcb bolodi kapangidwe ndi pcba
Ndikukhulupirira kuti anthu ambiri aliwodziwika bwinondi pcb bolodi kamangidwe ndipo nthawi zambiri amamva m'moyo watsiku ndi tsiku, koma iwo sangadziwe zambiri za PCBA ndipo ngakhale kusokoneza ndi matabwa kusindikizidwa dera.Kotero kodi pcb board design ndi chiyani?Kodi PCBA yasintha bwanji?Kodi ndizosiyana bwanji ndi PCBA?Tiyeni tione bwinobwino.
*Za pcb board design*

Chifukwa chakuti amapangidwa ndi makina osindikizira amagetsi, amatchedwa bolodi "losindikizidwa".The pcb bolodi ndi yofunika pakompyuta chigawo chimodzi mu makampani amagetsi, thandizo kwa zigawo zikuluzikulu pakompyuta, ndi chonyamulira kwa kugwirizana magetsi zigawo zikuluzikulu pakompyuta.Ma board a PCB akhala akugwiritsidwa ntchito kwambiri popanga ndi kupanga zinthu zamagetsi.Makhalidwe ake apadera akhoza kufotokozedwa mwachidule motere:

1. Kuchuluka kwa mawaya, kukula kochepa ndi kulemera kwake kumapangitsa kuti pakhale miniaturization ya zipangizo zamagetsi.

2. Chifukwa cha kubwereza ndi kusinthasintha kwa zithunzi, zolakwika za wiring ndi msonkhano zimachepetsedwa, ndipo nthawi yokonza zipangizo, kusokoneza ndi kuyang'anitsitsa kumasungidwa.

3. Ndizopindulitsa kupanga makina ndi makina, kukonza zokolola za anthu ogwira ntchito, komanso kuchepetsa mtengo wa zipangizo zamagetsi.

4. Mapangidwewo akhoza kukhazikitsidwa kuti azitha kusinthana mosavuta.

*Za PCBA*

PCBA ndi chidule cha kusindikizidwa dera gulu + msonkhano, ndiko kunena, PCBA ndi ndondomeko yonse ya kulumikiza kumtunda kwa bolodi akusowekapo za bolodi kusindikizidwa dera ndi kuviika.

ZINDIKIRANI: Kukwera pamwamba ndi kufa ndi njira zonse zophatikizira zida pa bolodi losindikizidwa.Kusiyanitsa kwakukulu ndikuti ukadaulo wokwera pamwamba sufuna mabowo obowola mu bolodi losindikizidwa, zikhomo za gawolo ziyenera kulowetsedwa m'mabowo obowola a DIP.

Ukadaulo wokwera pamwamba pa Surface Mount Technology (SMT) makamaka umagwiritsa ntchito makina osankha ndikuyika kuyika tinthu tating'ono pa bolodi losindikizidwa.Kapangidwe kake kumaphatikizapo kuyika kwa PCB, kusindikiza kwa solder paste, kukhazikitsa makina oyika, uvuni wa reflow ndi kuyang'anira kupanga.

Ma DIP ndi “plug-ins”, mwachitsanzo, kuyika magawo pa bolodi losindikizidwa.Zigawozi ndi zazikulu kukula kwake ndipo sizoyenera kuyika teknoloji ndipo zimaphatikizidwa mu mawonekedwe a plug-ins.Njira zazikulu zopangira ndi: zomatira, plug-in, kuyendera, kutenthetsa mafunde, kupaka maburashi ndi kuyang'anira kupanga.

*Kusiyana pakati pa ma PCB ndi ma PCBA*

Kuchokera kuzomwe zili pamwambazi, titha kudziwa kuti PCBA nthawi zambiri imatanthawuza kukonza, komanso kumveka ngati bolodi yomalizidwa.PCBA akhoza kuwerengeredwa pambuyo njira zonse pa bolodi kusindikizidwa dera zatha.Bolodi losindikizidwa ndi bolodi losindikizidwa lopanda kanthu popanda zigawo zake.
