Following Samsung, Corsair, Micron's Crucial, and Patriot, Taiwan's memory-equipment maker A-DATA's single 8GB DDR3 memory also officially appeared in the Japanese market. A-DATA's single 8GB memory frequency is also the most popular DDR3-1333 (PC3-10600), using Japan Elpida particles, timing is CL = 9-9-9-24, the default operating voltage is 1.5V. The biggest bright spot is that in the Japanese market where hardware prices are generally high, the price of A-DATA's 8GB DDR3-1333 memory has fallen below 10,000 yen, and the current price is 9,980 yen (about 830 yuan). Although the price/performance ratio is still a lot worse than a single 4GB version, but from the beginning of September when a single 8GB sells down to 26,000 yen to the current level, perhaps after a period of time 8GB will become a high-end standard model.
Do you know what is ENEPIG in PCB?
What is ENEPIG?ENEPIG-Electroless Nickel Electroless Palladium Immersion Gold is a surface finish for Printed Circuit Boards.ENEPIG works well with lead free and conventional eutectic solder alloys.This is the best way for gold wire bonding. Advantages for ENEPIG:
1.[Black Nickel" free – no possibility of grain boundary corrosion of nickel surface by immersion gold
2.Palladium acts as an additional barrier layer to further reduce copper diffusion to surface, thus ensuring good solderability
3.Palladium completely dissolves into solder, without leaving an excessively high P% rich interface, exposing an oxide-free nickel surface allowing reliable formation of Ni/Sn intermetallic
5.Withstands multiple lead-free reflow soldering cycles
6.Demonstrates excellent gold wire bondability
7.Process costs substantially lower than electrolytic nickel gold or electroless nickel electroless gold
