PCB board sinks gold and gold plated board
The gold plate and the gold plate are commonly used in the production of pcb (Printed circuit board supplier ). With the integration of IC higher and higher, the more IC feet, the more closely. The pad blowing flat and vertical tin spray process is difficult to be fine, which gives the SMT mount brought difficulty; in addition HASL inactive life is very short. The gold plate just solved these problems. For surface mount technology, especially for the 0603 and 0402 ultra small surface mount pads, because the quality is directly related to the smooth process of solder paste printing, on the back of the reflow welding quality plays a decisive influence, therefore, the whole plate gold in high density and ultra small surface mount technology often see.
PCB (pcb manufacturer in china ) in the trial stage, affected by factors such as the component purchasing tend not to immediately board welding, but often have to wait a few weeks or even months before use, gold plate for life (shelf life) many times longer than tin plate. So we are willing to adopt. So we are willing to adopt. And PCB in the sample stage of gold cost and Pewter plate not much difference.
