We now produce single sided PCBs based on through hole technology,but we want to go for manufacturing boards with SMD components. Is their any special arrangements or machinery that must be used in megrating to SMD ,i.e special type of silk or flux or inks or any other material. Plz give me any information regarding this question. -- Khaled H.
