SMD ndiye chidule cha Surface Mounted Device, chomwe chimayika zida monga makapu a nyale, mabatani, tchipisi, ma lead, ndi utomoni wa epoxy mumitundu yosiyanasiyana ya mikanda ya nyali, kenako ndikupanga ma module owonetsera a LED powagulitsa pa bolodi la PCB mu mawonekedwe a zigamba.

Zowonetsera za SMD nthawi zambiri zimafuna kuti mikanda ya LED iwonetsedwe, zomwe sizimangoyambitsa kulankhulana pakati pa ma pixel, komanso zimapangitsa kuti chitetezo chisamagwire bwino, chomwe chimakhudza kujambula ndi moyo wautumiki.

Chithunzi chojambula cha SMD microstructure

COB, yofupikitsidwa ngati Chip On Board, imatanthawuza ukadaulo wa ma CD wa LED womwe umalimbitsa tchipisi ta LED pama board osindikizidwa (PCBs), m'malo mogulitsa mapaketi amtundu wa LED pa PCB.

Njira yopakirayi ili ndi maubwino ena pakupanga ndi kupanga bwino, mawonekedwe ojambulira, chitetezo, komanso kugwiritsa ntchito kagawo kakang'ono.
