I. Rosin olowa chifukwa ndondomeko zinthu
1. phala la solder likusowa
2. Kusakwanira kuchuluka kwa solder phala ntchito
3. Stencil, kukalamba, kutaya bwino
II.Rosin olowa chifukwa cha PCB zinthu
1. PCB ziyangoyango ndi oxidized ndipo ndi osauka solderability
2. Kudzera mabowo pa ziyangoyango
III.Rosin olowa chifukwa cha zigawo zikuluzikulu
1. Kusintha kwa zikhomo zamagulu
2. Makutidwe ndi okosijeni wa chigawo zikhomo
IV.Rosin olowa chifukwa cha zida zinthu
1. Chokweracho chimayenda mofulumira kwambiri potengera PCB ndikuyika, ndipo kusuntha kwa zigawo zolemera kumayambitsidwa ndi inertia yaikulu.
2. SPI solder paste detector ndi zida zoyezera za AOI sizinazindikire zokutira phala la solder ndi zovuta zoyika munthawi yake.
V. Rosin olowa chifukwa cha mapangidwe zinthu
1. Kukula kwa pad ndi pini ya chigawo sichikugwirizana
2. Rosin olowa chifukwa cha zitsulo mabowo pa pedi
VI.Kulumikizana kwa rosin chifukwa cha zinthu za opareshoni
1. Opaleshoni yachilendo pa PCB kuphika ndi kusamutsa zimayambitsa PCB mapindikidwe
2. Ntchito zosaloledwa pagulu ndi kusamutsa zinthu zomalizidwa
Kwenikweni, izi ndi zifukwa zolumikizirana rosin muzinthu zomalizidwa mu PCB opanga opanga zigamba za SMT.Maulalo osiyanasiyana adzakhala ndi mwayi wosiyanasiyana wa ma rosin.Imakhalaponso mwachiphunzitso, ndipo nthawi zambiri sizimawoneka muzochita.Ngati pali china chake cholakwika kapena cholakwika, chonde titumizireni imelo.
