Hi Scott, Mark Wang just manufactured a 8L(2+4+2) HDI pcb prototypes for me,the PCBs min trace width/space is 2.75/3mil,I worried about the quality very much when I place the pcb job to Mark.but in fact,the 8L(2+4+2) pcb's quality is very nice,I w

Thomas, I know a HDI PCB house from China,They manufactured some high complex HDI jobs for me,some HDI pcbs are 10L(3+4+3),(4+2+4),and 12L(4+4+4),and some HDI pcb jobs are 2/2mil min trace width/space,the quality are very nice,you can make a try.t

How susceptible are the metals used in modern electronics manufacturing to corrosion by common beverages? This is a question of interest, especially to manufacturers, retailers and to a certain extent end customers. In this study the dissolution of aluminum, copper, gold, iron, lead, nickel, SAC305 solder, silver, tin and zinc was examined. Individual foils of these materials were fully immersed in one of sixteen chosen beverages and heated for 3 days at 40°C. The resulting solutions were analyzed using ICP-OES. The data were examined in light of the known pH, conductivity and ionic contents of the beverages, determined in previous work. Conclusions about the relative susceptibility to corrosion of the various metals and the corrosive power of the different beverages are made.
