Kodi PCBA ndi chiyani?
PCBA imayimira Printed Circuit Board Assembly, imatanthawuza ma board ozungulira omwe amasonkhanitsidwa ndi zida zamagetsi monga diode, transmitter, capacitors, resistors, ndi ICs okhala ndi SMT, DIP, ndiukadaulo wapamsonkhano wa soldering. Zida zonse zamagetsi zili ndi PCBA, ndipo zida zamagetsi zili paliponse. Amachokera ku mafoni a m'manja kupita ku uvuni wa microwave komanso kuchokera ku laputopu kupita kumagalimoto.

Awiri Common PCBA Technologies

Surface-Mount Technology (SMT)
Ndi teknoloji yomwe imayika zida zamagetsi pamtunda wa PCB mwachindunji. SMT ndiyoyenera kuphatikiza tinthu tating'ono komanso tcheru monga ma transistors pa board board. Ukadaulo uwu umathandizira kupulumutsa malo ambiri chifukwa palibe chifukwa chobowola zomwe zimapindulitsanso kufulumizitsa kupita patsogolo. Kuphatikiza apo, pogwiritsa ntchitoukadaulo wapamwamba kwambiri, zida zamagetsi zimatha kusonkhanitsidwa pamwamba kwambiri, kotero kuti mbali zonse za PCB zitha kugwiritsidwa ntchito.

Kupyolera mu Hole Technology (THT)
Njira ina ndi Thru-Hole Technology, yomwe imagwiritsidwa ntchito ndi anthu kale kuposa SMT. THT ndi teknoloji yomwe zida zamagetsi zimalowetsedwa m'mabwalo ozungulira kudzera m'mabowo, ndipo opanga amafunika kugulitsa gawo lowonjezera la waya pa bolodi. Zimatenga nthawi yochulukirapo kuposa SMT, komabe ili ndi zabwino zina. Mwachitsanzo, pogwiritsa ntchito ukadaulo wapabowo, zida zamagetsi zimamangiriridwa ku bolodi mwamphamvu. Chifukwa chake, ukadaulo uwu ndi woyenera pazinthu zazikulu zamagetsi monga ma coils ndi ma capacitors, omwe amatha kupirira mphamvu zambiri, voteji yayikulu, komanso kupsinjika kwamakina.

Kodi RHSMT ingakuchitireni chiyani?
1.Makina opangira ma SMT : Mukafuna kuwonjezera mzere wa SMT, RHSMT ndi chisankho chanu chabwino, timapereka makina oyika atsopano kapena ogwiritsidwa ntchito a SMT. Zoonadi, zida zogwiritsidwa ntchito kale zimasamalidwa, zimakhala ndi maola ochepa ogwira ntchito, ndipo zili bwino.

2.Zigawo za SMT : Mutha kukumana ndi kulephera kwa makina komwe kumapangitsa makinawo kuti asiye kugwira ntchito. Zimatenga nthawi yayitali kuyitanitsa zida zosinthira kuchokera kufakitale yoyambirira, ndipo mtengo wake ndi wokwera mtengo kwambiri. Khalani omasuka kulumikizana nafe. Kwenikweni angapereke mitundu yonse yodziwika bwino (mongaPanasonic,YAMAHA,FUJI,JUKI,KHUMI,ASM,SAMSUNG, etc.) makina opangira zowonjezera.
