Cost: the process is costly and time consuming. Disadvantages. advantages:: 1. for plinking and speeds less than 1200. But then again, we don't reload more then 3-5 times before we lose the brass for good at competitions. Unalloyed it's as strong as some steels but less dense. Zinc Plating Zinc plated steel products are fasteners wire goods, electric switch boxes and sheet metal parts. 001 10 u 12 pH of Solution *Development document for proposed effluent limitations guidelines and new source performance standards; copper, nickel, chromium, and zinc segment of the electroplating point source category. Advantages, disadvantages and applic ation scen e of different PCB surface treatment technics PCB technology has undergone tremendous changes along with the continuous development of electronic science and technology, and the manufacturing technics needs to be improved. It does add additional masking and stripping operations so it will increase the cost of the circuit slightly. question_answer Answers(2) edit Answer. Anyone involved within the printed circuit board (PCB) industry understand that PCBs have copper finishes on their surface. Nickel steel is used for armour plating. The plating process was done at 140 degree F and the quality of coating was not good. With the development of basic industry and high-tech products, the demand for high quality, high efficiency surface modification and coating technology extends to the depth. • Since most environmental samples contain a large number of organisms, each has to compete with others to grow on the media. An alternative solution is to apply solder paste to the test pads to ensure positive contact.
