Msika wamakono, gwero lodziwika bwino la kuwala kwa PCB laser kudula limaphatikizapo Green laser ndi UV laser. Ma laser awiriwa ali ndi ubwino wawo m'mbali zosiyanasiyana. UV laser ili ndi mphamvu yabwino yokonza koma liwiro lochepa lokonza pomwe Green laser ili ndi liwiro lalikulu lokonza ndipo mphamvu yake yokonza si yabwino ngati UV laser. Ogwiritsa ntchito amatha kusankha gwero la laser la makina odulira laser a PCB laser kutengera zosowa zawo komanso bajeti yawo. Kuphatikiza apo, Inngu UV laser ndi chisankho chabwino cha makina odulira laser a PCB. Pa makina oziziritsira UV laser, ogwiritsa ntchito amatha kusankha S&A Teyu refrigeration water chiller unit.
Ponena za kupanga, S&A Teyu yayika zida zopangira zopitilira yuan miliyoni imodzi, kuonetsetsa kuti njira zosiyanasiyana zikuyenda bwino kuyambira pazigawo zazikulu (condenser) za chiller cha mafakitale mpaka kulumikiza zitsulo; pankhani ya mayendedwe, S&A Teyu yakhazikitsa malo osungiramo katundu m'mizinda ikuluikulu ya China, zomwe zachepetsa kwambiri kuwonongeka komwe kumachitika chifukwa cha mayendedwe ataliatali a katundu, komanso kukonza bwino mayendedwe; pankhani ya ntchito yogulitsa pambuyo pogulitsa, nthawi ya chitsimikizo ndi zaka ziwiri.
